Gotta love the whole talk about "sensible" right after detailing absurd stats 😄
its always nice catching someone you fangirl over in the wild =)
I’m currently building an e36 GTR silhouette with double wishbone suspension. Should make some decent footage for hillclimb monsters in 2025 .
I plan to have it in thunder saloons and possibly Quick 60 if all goes to plan. ( similar to James clays / Georg Plasa) .
Man, those are mind blowing numbers! When you stated the target weight, performance and rpms, I had a feeling it was going to be a motorcycle based V8 turbo.
I own a sportsbike, and have ridden the S1000RR. I still feel grateful that we are able to buy a essentially 1:1 hp:kg vehicle that is affordable, road legal, reliable enough to be ridden everyday and has reasonable enough maintenance intervals and costs.
Using the Motec software with Assetto Corsa is such a great tool! I'm currently trying to build my proficiency in AiM's RaceStudio software, but both Motec and AiM software can work with AC, and do essentially the same thing. I'm pretty sure you need to use mods to work with the Motec software, but AiM will work "out of the box". For anybody interested in learning how to do race engineering, this is one of the easiest ways to get into it and build some valuable skills. And using it as a driver-in-the-loop simulator is cool, I'm glad to hear that it correlates pretty well. I guess I need to start learning how to input my designs into assetto corsa.
Also, this build just keeps getting crazier while being one of the most grounded and thought out series I've seen in a long time.
I was about to go to bed. Now I'm not. Wtf
This has gotta be my favorite upcoming build. The ideas and reasoning are simple and brilliant
I really hope to see the details of the build! Really exciting stuff
Love the series and I’m really excited about the engine choice coming from motorcycle racing. Looking forward to follow along on the journey!
Glad to see synergy getting some more mainstream love.
Oh man, was hoping for a rotary :)
Hope one day that Assetto Corsa mod can be released. Would be awesome to drive this car in a sim
The K48 twin turbo by Neutron Engines was what I was hoping for. But I don’t know when that will actually exist.
I was thinking about that one too, but I think it'd be way too heavy. Even a single K24 is already at his target weight.
A friend of mine works at Prototipo and I have toured their factory. I will hit him up to see what I can help with on yours, if anything, or at least see it in person before it ships :-) neat.
Thank you! You are very generous with your knowledge and experience. Even though the scope of what you're doing is far beyond what I hope to do, I learn a lot just following your journey with your new build.
I would love a video on building custom models in AC.
Or if you know of existing sources for that info.
But I’m interested in the nuances of building models for the purpose of Driver-in-the-loop type sim testing, which is probably not a common topic in AC car model building tutorials elsewhere.
There are drifters that spray nitrous the whole time, but their runtime is also limited.
one of one- hope it works- wish you the best
Been waiting for this video, hell yeah!!!
ha, I was right! Great to hear you are using Prototipo's S1000rr based Synergy v8. Def the engine I would use. I dream of making a 3L V12 engine based off these heads.
I would just go full GMA Cosworth at that point. Heavy, but probably takes boost no problem. That engine is rated for well over 50k miles
@@Shadowboost I'd be doing it just for the love of make my own thing.
Robin I really appreciate the thinking that is going into this project and your willingness to share your insights. And in my own small way I would like to support the project. Are you going to sell Merch (I liked the T shirt you wore in part one ) or start a Patreon?
Good lad, man after my own heart. Struggles I’ve had with managers wanting plans to the Nth degree when you just need to get on with it!! I also do appreciate a bit of analogue, conceptual design. I, personally, hate computers. A necessary evil!
Engine choice, spot on.
Keep up the good work.
Thanks for another great vid. I'm already looking forward to the next one!
Love these insights into how you built the race car.
Love these videos. Keep going
you should 100% share the wolf's assetto build one day
thank you a lot for answering my question, I definitely related to what you said and still think its very helpful to atleast know im not alone or terrible at managing my projects🤣🤣I feel slow when i dont hit my target deadlines but you're right, I just need to be hard on myself with a healthy mindset!
rev-x oil supplement to prevent corrosion when running methanol
Steve Morris swears by revX
looking forward to this
Exciting! Watching!
I’m curious if you looked at the Italtecnica 3.0L Pre Chamber V6. It would probably have been out of the price range but it did also seem to have been a engine that fit your criteria (light, high power, reliable) as it was intended for Le Mans Hypercar when they still planned for over 1000hp in those cars.
Revs too low, requiring a much bigger gearbox. Also, but sure if they ever designed it for a true 1000 hp. Hypercar class is 650 right now and with their extra headroom, it was designed for 750ish with quite high complexity/exotic cost
@@Shadowboost The original Hypercar ruleset had higher power levels and higher weights around 850hp.
Mike Patey comes to mind regarding high altitudes and NOS.
Sid you consider an alloy in line 6 cylinder like BMW’s S58 with a larger turbo and dry sump? Must weigh more than 100kg but bot much and well good for 1,000hp. More reliable than a 2.6litre bike based V8. Perfect primary and secondary balance. You could even use nitrous on the top of the mountain to keep the power up.
great vid. Have you chatted with Alan Millyard yet?
Accessible and sensible technology: AWA composites ❤
Should have hit up AER in the UK....
Have you considered charge cooling via water/meth injection in addition to intercoolers, as I understand it it's relatively light for the intake cooling it provides
Ryan Falconer sells old Indycar v8s from the 90s. Chevy branded but I think Ilmor built them.
Imagine using an unrestricted super formula or super gt engine, or even better combining 2 super GT engines together.
billet 13b semi PP would hit the targets for weight and power.. if you can afford it
The Synergy V8 has been in Reg Cooke's land speed cars.
He was also selling a Judd V10.
Would this car be a good place to use Subaru’s rocket anti-lag system?
I'm guessing that hypercar manufacturer is Czinger
Curious your opinions about unsprung aerodynamics? Considering how bumpy the mountain is it seems worthwhile.
I can't say I know his opinion, but generally the problem seems to be that significant unsprung aero leads to excessive unsprung mass.
Additionally, you can get a lot of the advantages of unsprung aero with slightly more sophisticated suspension. Particularly what I believe is called mode decoupling. Witch works that all four tires being pushed down equally are affected by a different spring rate than any one or two tires.
Or maybe I'm completely wrong and his next car will be a torpedo with giant wings where the control arms should be
your thoughts on "rocket" anti lag ?
Bike stuff is just mega though... But can't dismiss aer and there experience in designing turbo endurance engines...
The "Mazda" based Daytona prototype does like 950 unrestricted....sub 20 psi ...
Curious if you ever considered any turbine engines, eg a turboshaft out of a helicopter. From some quick googling they don't seem to sit too far off 1000hp 100kg, and be quite reliable, although it seems like throttle response and varying speed in general would be very problematic.
As always, loved the video, I've already learnt so much from what you have shared :)
Throttle response would be horrible. In theory, a racing CVT might just make it work. But I don't think anyone has made a racing CVT since Williams F1 team.
Just curious are you familiar with Elmer Racing and their Thor engine?
the synergy 2k is 92kg NA, no? with boost it should be at least 150??
Would nitromethane be an option? Or at least why not run a blend to reduce oxygen requirements?
So many factors to consider, literally thousands of variables. Apart from 2D cad drawings for laser cut parts all my designs are in my head and physical
Mockup/ prototypes .
Kinda old school but works for me in a fashion. 😵💫.
Integration is the key for lightweight, along with simplicity and a dash of thinking out the box .
Nice video and all interesting stuff. 👍🇬🇧
What about a very large spring
Glorified wind up car
I gotta ask.....wouldn't a 4-rotor rotary engine also match these requirements? I suppose the time required to build and prove out such an engine would be a problem for the program, but it would be cool to see and hear!
Rob Dahm collab incoming....? ; )
Nope. Rotary is VERY heavy in comparison. Think double the weight
@@Shadowboost Oh... I thought rotarys are light weight compared to a lot of car engines? But I don't know the actual weight. I guess he is talking a lot about motorcyle derived engines....
@@fredygump5578 rotaries are heavy for car engines, comparatively. The 787B 4 rotor is 400 pounds and that's naturally aspirated without forced induction. For comparison, the Porsche 962 engine that it was competing against weighed 385 pounds and that was with turbos, more power under the curve and still lighter
Exstreamly unefficient you'll have to replace the weight in fuel.
How would a cotswold or judd v8 or maybe a super gt gt500 or Super Formula engine but tuned
I wonder is that 4 cylinder Elmer racing engine could have worked
Next step is 1kw per pound
Go kiwi
Get a 3000GT VR4 motor change it from twins to quad turbocharged.
a 3000gt vr4 motor is way heavier than 100 kg, and more turbos doesnt make more power
Robin have you ever considered a turboed nascar v8? The dodge r5/p7s are cheaper and rev to 9k 358cui 800-900hp n/a 550ft/lbs of torque
What would that weigh?
@@cameratool so i asked this with out knowing myself. After a quick google search they weigh fully dressed besides the dry sump pump 435lbs. A touch too heavy whoopsy
@@Moneygrip not too mention the size. The Ford open wheel guys already run engines like NASCAR. He covered it in the discussion about N/A
Might be because I'm American but when I hear 1-1 I'm thinking horsepower and pounds which is a little harder lol
1:1 hp/lb is precisely what Robin is shooting for.
@@phillglasson6357 yep, I kind of figured that's where he was going with it and I have since seen.
Didn't articulate my point well, I've always been confused as to why people would say 1-1 hp to kg because that feels like a really unnecessary way to mix units, that mostly exists for marketing claims on supercars.
How about 1hp/1lb at the top of the mountain ? Aim big 😂
how was the k20 only a 300 mile engine at 650? turbo k20s make 1000 hp in street cars
You can’t compare a street car that will do a few pulls on the highway to an engine that will go at full tilt all 300 miles of it. Put that engine in a hillclimb car and it will grenade itself in no time.
That’s the difference between hobbyist/enthusiast and professional motorsports grade.
Nitromethane?
1:20 next year the car is going to have a megawatt per gram
Hear me out, instead of a V8 from bike engines get a v12 from the i6 honda bike.
Will it meet the weight and power targets? Unlikely
Will it be affordable and manageable
Definitely not
BUUUUT
Will you be the coolest team on the mountain?
Absolutely
