15" wheels have less rolling resistance over 13" for the same overall diameter. When doing camber adjustments, remember to check your toe. Outside front gets hot when there's aggressive toe in. Good to hear the adjustable sways are getting adjusted!
100% agree. Bet if you go check your tracking the toe will have changed with the camber changes. Also great if you can get someone to help with the tyre temp readings. Even better get a tyre pyrometer that you push beneath the tread to take more accurate tyre temps. Normally I would mess with anti roll bar, damper settings etc. but I would only change camber between visits to the track to avoid the knock on impact to caster / toe.
Our series one RX7 we had 4.5 degrees camber on the front with between 1 and 1.5 mm tow out and our spring weight was 275lbs this is in Australia with Yokohama Ao50
With the new rims & tyres on, it transforms this machine into an aggressive monster and definately it looks better than before, performance wise & outlook wise ...........good choice .....I must also mention that your video recording is super and professionally done ....... Cheers buddy....
Totally agree with the choice on wheels. I never like it when I see an old Ford on big wheels and rubber band tyres but never say anything because I do not feel it my place to criticise other peoples car choices. One thing to consider is that drag increases to the square of speed so even if you had 400BHP you would not necessarily go any faster, rather like the Super Sevens. The great Jim Clark always liked an understeery set up on the grounds that it is easier to make an understeery car oversteer than it was to make an oversteery car understeer. That really is a terrific car you have built there!
Small wheels forever. Stumbled across your channel earlier today, and I'm excited to work my way through all your content. Love to see people that just 'get it'!
I like the smaller wheels and tires. Definitely agree with it's the proper look for that car. You are definitely hitting an aerodynamic wall on your top end. Have done the same with my superkart and no amount of ratio changing did any good. Well I could step up to a twin, but I'm going to stick with my single and try to work my cornering speeds as hard as I can.
Wow, another top vid! The mushy-pea is looking fantastic & with the new wheels, the stance is spot on. Great overview of the data-logger, really gonna help refine the lines & just so good to see you on the track after all the work! Crack on butty! 😁✌
That was very interesting Matt, amazing the information you can get from those details for your car / driving, it makes me understand more the amount of information they must get in F1 and what they do with it. Brilliant video and I love the stance the mongrel has on the right size wheels!! Wow!
Revolution Wheels who doesn’t love them on old fords or anything come to that ,Matt you must be proud of your achievements to take two cars and to turn them into a track slayer fanbloodytastic thanks Matt for the entertainment 👍👨🏻🏭
Very interesting, ratios sound absolutely on the money with that wheel size, plus they look perfect. It looks quick. The data collection is very powerful, fantastic to think you could fairly quickly find over half a second by changing your lines to optimise your own best lines, gotta be the cheapest half second you’ll ever gain.
The Mongrel is really becoming a real Trackday weapon. It really in its element on track. The only way your'e going to get much quicker would be to supercharge it but iI love the sound on the bodies. Perhaps leave the bodies and supercharge it and have a home made carbon fibre/ Aluminium inlet plenum. That would take the Mongrel and content to a new level!!!
@@Urchfab It looks to me like you have that chassis very close to the edge of its performance. We reach a point where more power becomes very difficult to keep up with the lower powered chassis of same configuration and spec. Only you can feel if there is more speed available in that chassis Matt. With those 13's it seems to be really stable under brakes , through corners at speed and you don't have any chirping or locking on that rubber either. It would be cool to get another 25 mph at the top end though.
Ever so slight under-steer is definitely better from a pure speed perspective. Even though it feels shite when the front end tries to push off line, you lose less momentum than when the back gets loose
Matt, I highly recommend nankang ar1 tyres over the toyos and this is from personal experience with both tyres especially if you notice the same de-lamination that I did. Either way the wheels look great and will handle far better without the stretch!
The Mongrel is soo good-locking on those wheels, Urch- English, classic and stylish! Street Machine cover car, if you remember the magazine. Not mind me asking, but I think it could take a taller gearing in the rear aksle. It revs pretty high, me thinks.
Outstanding footage of your untamed animal....as for all those graph's and squiggles, well that's all Greek to me but I do love this car and your work..... Thank you very much for sharing this with us all.
That joker in front of you was going like a dude in a computer game. I was gobsmacked that he just kept opening the gap. You have great traction on the smaller tyre.
Wheels look really good on it, your just like me Keanu g your head etc into the corners, I struggled like crazy to change that lol. Awesome stay safe bud.
Inspired choice on those wheels dude! Totally get what you mean with how it looks now. Gotta say, that’s a pretty rapid little mx100e you got there 👍🏼👍🏼
When using lap time analysis, always include the next straight. I.e. Time from corner entry (or mid corner) to the end of the next straight, as a compromise on corner time to achieve a faster exit will gain time along the next straight. The fastest time through a corner many be resulting in a slow exit time. The theoretical lap times can never be achieved due to the compromise of lines to achieve the real fastest lap time. Personally they should not be part of analysis software, and should be regarded as bling only. Remember the stopwatch never lies; the only number that matters is the lap time. I was astonished at the gain in speed when I first started to use lap time data logging, a very useful tool. Good luck.
Looks great on 13" wheels. I agree with the older cars huge diameter rings look awful and don't really serve a purpose the cars weren't designed for wagon wheels back in day. Looking good on the track there mate........ LAG
Definitely check out our monthly webinars with James Colborn, he'll help with understanding all of your acquired data and how to get the most out of it and Race Studio 3! Great video as always!
Awesome vid, loved this car from the start. Binged watched a bunch to follow the whole build. No experience whatsoever with track data tools but the graph seemed like it could be a shift point, acceleration, braking graph. The closest I've ever gotten is Gran Turismo. A .... lot......of......Gran.....Turismo. ; ) Well, and maybe a few high speed stints on some country roads. Regards and thank you for sharing.
This “perfect line” data is fascinating. I once lost a final when I “thought” if I took a wider line on the last corner I would maintain/ achieve a faster exit. That was 30 plus years ago and I remember it vividly as my challenger zipped under me and took the trophy. 😬
Yeah I'm old school, and like the 13inch on old classic car's, my escort had 13 with 215 /50/13 and 235/50/13 Bridgestone tyres, with 7 inch wide on the front and 8 inch wide rims on the back , looked great 👍🏽👍🏻 but getting them now cost way more now in New Zealand 😞 but worth it for the look 👍🏽 cool
Hi Matt, when doing tyre temps you really need to be doing via a temp probe to get the temp within the tyre, not just the surface temp. Surface temp can be quite different, especially by the time you have pulled off the track. 13" wheels look much better.
Yea Urch the smaller wheels look sweet, completes the look and the telemetry data looks like it'd rival that of an F1 team. Nice laps btw, would changing the gear ratios help?
Commented long ago that this car should be on 4 Spoke revolution wheels. All you need to do now to make it perfect is respray it in Gulf racing colours . And a turbo will make it pull 6th 🤣
The theoretical optimal lap time calculated by lap analysis software is often not possible in reality. The reason is that the optimal speed/position required for linked corners doesn’t coincide. For example optimal exit position for corner A may be off from optimal entry line for corner B and so on. I’ve never seen any software than can do smart chaining of lines to find a best overall optimized lap. Mostly, they just sum up best times for each segment without consideration for how one turn affects the next (and the next and the next…).
I missed something...You went from "Can't record lap times on track days" to "Here's all my lap times from all my sessions; let's compare lines." What's the distinction? You can't watch them in real time, but you can review them after the fact? I don't really understand why they would have the rule in the first place. Yup...I'm missing something. Likely several somethings. Regardless, these track day videos are entertaining and informative. Great to see all that hard work you put into fabrication result in fun times out on the track.
A lot of people don’t like 4 spike Revolutions but they’re one of my favourite wheels. They look perfect.
Love the data logging and camera. Know what I want for my birthday.
Also, im old enough to remember these way back.....I can't imagine what you could do with this car. Your knowledge and a time machine......
15" wheels have less rolling resistance over 13" for the same overall diameter. When doing camber adjustments, remember to check your toe. Outside front gets hot when there's aggressive toe in. Good to hear the adjustable sways are getting adjusted!

Probably not even quantifiable. Unless you're including deformation, which you want anyway, assuming you have enough tire for the load.
Thanks for the update. The Mongrel is looking good.
Cheers Brian
That is a sweet looking ride. At first I wasn't taken by the color, pea soup green, but it has grown on me and now I quite like it.
With the new rims & tyres on, it transforms this machine into an aggressive monster and definately it looks better than before, performance wise & outlook wise ...........good choice .....I must also mention that your video recording is super and professionally done ....... Cheers buddy....
New stance on those 13's looks awesome 👍
I agree 100%.....13's look so much better on the older English cars. Great choice.

Cheers Chuck, That's my plan too for now.
Pretty sure caterham super sevens hit a wall at some speed over a hundred and you have to remove the windscreen to go any faster 🤣🤣🤣
Mate you Superkart racers have big balls! Regardless if they are an 80cc, 125 or 250 single. You're mental! But the racing is great!
Definitely better
@@glensgraphix Thanks Glen, I have a 250 single and have some videos up on my channel.
That wheel and tire combo is PERFECT!!
Love the Revolution wheels, might be my imagination but the car looks like it is less twitchy now, plenty to be proud of, well done.
Wow, another top vid! The mushy-pea is looking fantastic & with the new wheels, the stance is spot on. Great overview of the data-logger, really gonna help refine the lines & just so good to see you on the track after all the work! Crack on butty! 😁✌

Wheels look good. The race data from the software package looks super useful.
Loving the Revolutions. I always thought they were the best looking wheel when I was messing around with Formula Fords in the SCCA.
I love the look there’s nothing like a modified classic
they look fantastic, great stance too. looking forward to seeing the mini done & on the track
Matt, I highly recommend nankang ar1 tyres over the toyos and this is from personal experience with both tyres especially if you notice the same de-lamination that I did. Either way the wheels look great and will handle far better without the stretch!
Ar1 are way better, never really thought the toyos were anything special
The Mongrel is soo good-locking on those wheels, Urch- English, classic and stylish! Street Machine cover car, if you remember the magazine. Not mind me asking, but I think it could take a taller gearing in the rear aksle. It revs pretty high, me thinks.
G'day,
Great video. Definitely the right move with the smaller wheels.
✌️ Peace from Australia.
100% agree. looks stunning
The car looks really, really nice.

Brilliant video Matt, that is one Awsome old lady you have built and it just gets better and better ❤
love the mongrel so slick looking and a very sweet ride Matt, cheers KC Cradle Mountain Tasmania Australia 🇦🇺🤝🇬🇧😎🙂👊👍
Cheers mate.
Hey you have build a solid race car watching from you pulled the mx 5 from the bush..... Cant wait for the mini
That joker in front of you was going like a dude in a computer game. I was gobsmacked that he just kept opening the gap. You have great traction on the smaller tyre.
It just sounds so awesome!
If you're doing track days and not racing, you just "race" yourself to improve your times so who cares. And they look spot on! Thumbs up
Indeed. Cheers
Wheels look really good on it, your just like me Keanu g your head etc into the corners, I struggled like crazy to change that lol. Awesome stay safe bud.

Like the look. The software is fascinating.
Looks fantastic on 13's
looks stunning
I must say I prefer these wheels to the other ones, amazing what data you get with that AIM tech. :)
it looks outstanding!

Definite improvement with the 13" wheels!
Exactly as it should look!!!!!
Yip now that is right. Looks great, proper looking old Ford.
Little ripper. Good work Matt
It looks perfect.
That software looks good. Will be nice comparing different vehicles.
Nice colour wheels! Love them!
Looks great on 13" wheels. I agree with the older cars huge diameter rings look awful and don't really serve a purpose the cars weren't designed for wagon wheels back in day. Looking good on the track there mate........ LAG
Looks much better matt :)
wonderful work, great car!
Die Revos sehen wirklich sehr gut aus👍
That looks really cool
Fab and retropower all on a Sunday top content 😎👍👍👍
Very good balance of wheel size and body volume. It’s cool 👍
Thanks! 👍

I will. Cheers
It definitely looks better with the 13" Revo's on Matt ;-)

love that little car ! it reminds me of my grandmother.......but looks like a scary little beast. lol
Revolution wheels certainly takes me back to my youth, that looks much better. 👍
That look really nice 👍
We need to fight all those big rim guys!
looks amazing
Back in the 60s my uncle had one of those old boxes ticked along just fine until you came along and buggered it up😎🤪 seriously bad asss ✌️
Cheers
Looks mint on 13👍
Looks great 👍🏾
Good choice on the tires.
That's the right size!
Yeah I'm old school, and like the 13inch on old classic car's, my escort had 13 with 215 /50/13 and 235/50/13 Bridgestone tyres, with 7 inch wide on the front and 8 inch wide rims on the back , looked great 👍🏽👍🏻 but getting them now cost way more now in New Zealand 😞 but worth it for the look 👍🏽 cool
Souns cool mate, love an Escort!
Looks much better and always loved revolutions. Just needs a turbo now to overcome the 100mph limit 😜
Looks great mate
Thanks 👍
If they don't get it, F them. It's your car, you are the only one who needs to be happy with it. BTW it looks great with the new wheels.
Cheers
Sweet.
I said a few months ago it'd suit white 13 inch Revolution 4 spokes better.
Great minds, etc.
Love the Mongrel.
Hi Matt, when doing tyre temps you really need to be doing via a temp probe to get the temp within the tyre, not just the surface temp. Surface temp can be quite different, especially by the time you have pulled off the track. 13" wheels look much better.
I will get hold of one. Cheers
New wheels and tyers are look great. 2x👍
I do really enjoy this style of video. Would love to see the Mushy Pea on track myself one day!
Come out to the track and I'll take you for a spin.
@@Urchfab I'll hold you to that for sure! Heading to Cadwell again anytime soon?
It would make an killer street car👍👍😁🇦🇺
Perfect
That beast has fun written all over it!
if aero/power wall is limiting your lap times, it's going to be all about corner speed.
centralised mass is the go.
The next step looks like supercharging or turbo to improve performance
Maybe.
Was thinking its time for a supercharger
Yea Urch the smaller wheels look sweet, completes the look and the telemetry data looks like it'd rival that of an F1 team. Nice laps btw, would changing the gear ratios help?
Don't think so mate. Cheers
Looks boss 😎👌
Awesome with a capital AWESOME!
Best way to get passed that 100 mph brick wall.....Boost🤘
Could be!
Maybe some diffusers are needed to reduce the effects of all that frontal surface area. The Mongrel just keeps getting better!
Looks loads better , the black steels looked good, shame they didn’t work
Most interesting -
Ford on Revo’s 💪♥️
Does the smaller diameter wheel make the steering a little more lively?
Looks amazing btw :)
That looks way better bud
Commented long ago that this car should be on 4 Spoke revolution wheels. All you need to do now to make it perfect is respray it in Gulf racing colours . And a turbo will make it pull 6th 🤣
Was the mx5 an import? Looks like the Japanese speed restriction the way it bounces at the same speed every time
Its on a standalone ecu so wont have any limiter on it.
