A single Precision 8385 turbo pushing out 33 PSI and Nitrous force-feeds the H6 that has been bored out to 3.6L. In-house AFP cams & ported heads, an Arrow crank plus Mahle forged pistons are all vital pieces of the 1200 HP puzzle along with an EcuTek tuned GT-R GR6 transaxle dual-clutch gearbox that lives forward of the rear axle with a chain-driven Escort Cosworth diff driving the front wheels. This packaging gives the car a balanced 51/49 weight split with the aid of a causal 600 - 700mm engine relocation towards the rear.
Alcon brake calipers help pull the car up for the corners and Andrew Brilliants aero input helps keep traction and control at high speed. A Life Racing PDU keypad and AiM displays allow Andy to make and monitor adjustments on the fly. One interesting future addition in the same vein will be the ability to adjust the ride height on the go via one of Andys own numerous engineering experiments.

Im loving the fact that the driver of the car actually knows his car and clearly works on it too 👍
Eetu Kopsala 2 right the drive built the car with his own hands, he’s a Scottish genius
Hes basically a Legend in British motorsport and among British car enthusiasts.
Andy is a legend
Bro that’s Andy forest Scottish rally / motorsport/ tuning legend if he don’t know it it ain’t worth knowing
He doesn't just work on it he built it himself
Wow, what a great interview, this guy really is engineering the shit out of this car. Very cool to see, much better than most of the other stupid interviews I see around.
Cheers and thanks for your discussion mate! - Taz.
Both accents were great the car is awesome!
I wish I could give 2 thumbs up
I really enjoy your work, its satistifiying to listen to since you have intelligent questions that picks up all the interesting points.
It's easy with someone like Andy who has a lot of really interesting ideas and the skills to explain and implement them as well :) - Taz.
High Performance Academy He always ask the questions i would have asked myself, its magic :) (im an oem engine developer and hobby racer ). Im new to this channel, surprised it hasn't more subs, top quality content!
Automotive content at its best.
Nothing dumbed down, informed questions asked of someone who is at the cutting edge.
Great stuff. More of this please.
By far the most refreshingly creative example of a tuner car built for WTAC competition! Reading through various articles written on the build of this car don’t quite do it justice at all, in contrast listening to Andy himself reflect on a brief technical appraisal during this interview has been so much more rewarding from an enthusiast’s perspective. A truly clever approach which tethers on the edge of what’s practically possible when bending what’s theoretically known the only gives a glimmer to the shadow of the treasures this car holds as a complete project! Many thanks as always for this interview!
Refreshing video to watch...
Two smart chaps at their element!
Yesssss! Been hanging out for this! I love this Scottish genius!
Yes he's always got some really interesting ideas and solutions on the go! - Taz.
Greatest inventors in history were Scots, this man is a genius ok!
First time hearing of a chain driven time attack car
It's something a bit different eh! - Taz.
It's not a car it's really a go-kart in disguise :-):-):-)
Genius system because of lightweight
Well technically only the front end is. But yeah it’s nuts!
Jesus, this guy has more than half a clue of what is going on. Very good job HP Academy. And props to this scots man
It's always refreshing to see a RUclips channel responding to questions and comments on a video almost a year old!
We do our best! Even at a year old or older so many of these videos still hold 100% relevant, useful and interesting (if you love learning about anything automotive) knowledge 😎 - Taz.
please take this to goodwood and go up the hill
This man, Mr Forrest is a genius on many levels, and its exciting to see him push the limit!
Nice 49/51 for a wrx is pretty damn good. So awesome to hear how this car works, super cool.
7.7s car that can turn?? that's very un-American! What an awesome machine. This is real engineering, not just slap a bigger engine and turbo on a car to go fast in a straightline. And goddamn the interview, I love how the host gives background to each question before actually asking the question to help viewers understand and appreciate why he's asking the question! That's university stuff.
I love these tech tours man, so much information!
This is probably the first time I've ever watched an interview this long, and I'm really glad I did. This guy/car is freaking amazing!! Well done with that chain drive system!! That's insaine!! And I bet that listening to the passenger never gets old 😉😉🤘
Who gave this a dislike??? The interviews with Andy are always very detailed and are very well presented! Some great mechanical knowledge to be gained here. Keep up the good work guys!
_"Who gave this a dislike???"_
Charlie Shaw. :D
that in-car footage...that thing is a rocket!
That turbo spool --- all the sounds are just right!!!
Oh man !! The sti i have sounds and performance like this machine!! Its a 2011
The Aussies are on another level with Subaru... I know he's a Scott but he's racing in Australia.
brilliant vid, amazing discussion of the new car... some incredible changes from the old car...
chain driven offset front drive shafts, r35 transaxle, turbo eating into the passenger footwell. amazing build and total defiance of limitations with such innovation - Andy is just inspiring - oh and his aero guy is something else too!
Andre gives yet another great interview with Andy. Thank you Andre, I just love these interviews. (y)
Awesome bloke and awesome car for sure! We've got an interview with the aero guy, Andrew Brilliant, coming up soon too ;) - Taz.
I love that after u guys chat about the Tec of the car and we as viewers build a picture up of spec and the passion that go into them it's then for me brought together in the car doing a lap, genuinely the best motor car/Tec video's FULL STOP. 4 years late to this vid but loved it fellas. ✌🖒👊
I'm back for the third time taking this car in due to what I thought was an unrelated search lol. What an incredible piece of engineering using relatively novel solutions. Thanks for all you do Andre
Wow, what an awesome machine! Hearing all the ideas and reasons for doing different things with the car was suuuuuuper interesting, I love it!
Very impressive. The torque must be insain
6;05 Andre got a little thrill there knowing that this guy not only "identified it" but "said it" for us all to hear Dre knows hes interviewing a genuine guru (That's Gold) Top job TOP CHANNEL
This is a perfect balance, insight on the mechanics (main focus) and then those mechanics in action. Not sure If you guys recall my comment in a past video, I know you get quite a few. Not wanting a “Full race” channel, just a little more action showing how all those items work in motion.
GREAT AS ALWAYS GUYS!!
need pictures of it on hoist :D
This car is simply amazing.
I am so glad I watched to the end😋
Listening to Andy answering on Andres questions is one of the most relaxing things about cars on youtube apart from documentaries. So much knowledge, beautiful attitude, mindblowing details, calm and respectful pesonalities with no drama, only facts. Thank you HPE! :)
The worlds first awd subaru 7.7sec in the quater mile. Fastest euro car at wtac also fastest subaru at wtac. I have watched the progression of andys car from drag car to superlap scotland to doing both all the time and now in wtac he is one of a kind scotlands proud of ya big man🏴
Remember to Subaru frame not engine transmission really anything else in that car but it's a WRX right
@@jacobjordan7644 yup mate still a wrx at its core.
@AYE OK SURE dude shut the f****** up look at the comment again
What a great interview! The interviewer is very articulate and knows his stuff and knows great questions to ask! And the Scottish Lad is an engineering wizard and did amazing in the interview and didn't blapper on. 10/10

This is frigging genius some of the features on this car.
There needs to be more guys like this gent pushing boundaries and making it work.
Great stuff . Hats to the interviewer for the well researched questions . Top job
Wow... This man is SMART!
Really enjoyed the questions and format! I love the engineering on this car, it's my favorite of 2019 thus far. Will be keeping an eye on this especially for the 3rd spring tech, incredible.
Edit: Boy am i late to the party! Lmao
It's still awesome! - Taz.
Absolutely gutted that Andy sold this car, Really wanted to see the car evolve even more.
Do you have any info on where it is now? - Taz.
@@hpa101 the German chap who bought it is not on social media but I believe he will be competing in European time attack masters and German time attack, I can't find the guy's name though.
Cheers for that info anyway, I'll try keep an eye out for it. Shame we won't see Andy's new built at WTAC but I try and catch what I can about that too in passing =D - Taz.
Damn that looks so planted even with the boost kicking in at corner exit.
That is really one hell of a car. He's one of the true genius Mr Craniums of the motorsports world! I love that car, especially compared to the 2015 rendition. I'm starstruck really.
Wish that was my grandpa!!!!
I love your interviews with this guy, great questions as always, but actually great indepth and open answers as well
Thanks Tony! Glad you are enjoying them and thanks for the feedback =) - Taz.
Far out Andre, that thing is a piece of engineering art.
Prolly the third time Ive watch this video. Love the car and high level discussions, I love cars!
Haha you guys are surfing on the Cutting edge, and pushing the envelope of interviews. ;-)
I love this!!!! Milliseconds make seconds - add x amounts of laps = win!!! Amazing 'video/interview'
OMG that sound at the intro uffff
Fantastic on both sides of the mic
Seen this car at ten of the best in the UK, it goes off the line like superman kicked it up the ass.
This is one of my favorite cars js
This was a Fantastic video with great questions that really get at the interesting points of this build. 👌 Amazing work on both sides of the interview.
those are some crazy fast shifts. wow!
What a dynamite fella and an absolute genius. Good on ya mate 🍻👍
That’s him! That’s the guy that invented golf! I didn’t know he wrenched too. Fine work, damn fine.
Monstrous. Great build.
Awesome car hats off to Andy
He basically has “active suspension “ like Williams had in the 80s and 90s. In the front of the car. This car is just CRAZYYYY i love it.
Wow André! Wat a fascinating and excellent interview! Since 2015 always keen to check the evolution of Andy's 'Rex'. Fantastic ideas and solutions. I hope Racecar Engineering ( or similar )do an I depth article on the car ( with drawings 🤓 ) Cheers David
I think we could probably do an hour-long interview and still have plenty to talk about haha - Taz.
The leader in the sport in my opinion
My favorite video I've watched so far. It was nice to see the car up close and on the track in action. Subd
Andy is a very nice guy!
Chain driven...genious
What an accent ! It was intense for us, spanish speakers hahah
Great interview. Very interesting. Really enjoyed that.
Such an amazing channel! So underrated!
Cheers Brad! We still have HEAPS of videos to come from this years WTAC as well that you'll love - Taz.
I could listen to the Scottish guy all day!! What a legend!!
Turbo is the official copilot
Andre is in love with the scotsman haha
ruclips.net/video/iFx-5PGLgb4/видео.html - Taz.
This is the most crazy car ive seen in a long time
I’d love to see the mechanics of how the 3rd spring is able to control ride height. Is it somehow pivoting between the chassis and strut tops?
It’s a work of art and Andy is a mad scientist!
Huh. That sound took me by surprise. More like a very angry 930 or 964 Turbo.
Wow, what am amazing machine! Great engineering also!
Monster
I notice a lot of DTM and Formula 2 influences with this build! This is truly a custom racecar with a Subaru body shell. Im sure he would have built a scratch made racecar if rules permitted!
Has a ez30d. Owner this makes me smile 😎
It's not an EZ series engine, it's actually an EG33. It's from a Subaru SVX. Twin-cam (with single cam sprocket, they're linked internally with gears), 24v, 3.3L (though this one is stroked I believe). Basically an EJ22 with two more cylinders. Shares literally nothing with the EZ engines. Check out SubiPerformance, they have a video comparing the two engines internally. The EG has much thicker cylinder walls making it a better candidate for very high boost builds like this. Also, runs a timing belt instead of a chain like the EZ series, which although requires more maintenance, is much more efficient.
Love this car
that rack n pinion location is crazy
What a beast!
And the car is amazing, too!
Great interview! Makes me wish I was a car engineer! Loved it!
This.
Is.
InSANE.
So much info, what a fantastic build!
That man is my idol. If I was rich, I'd pay him do build a duplicate...
These are so good
I would have put this sideways into the sign at 15:59, which is why I drive a Kia now...
woah that car sounds amazing
Genius!
I remember this guy from Crail years ago.
This gentleman knows his shit!
Id love to take a look at this beast while its up on a lift. A gtr rear transaxle with the front diff behind the engine that chain drives the front tires in front of the engine. What an amazing engineering feat. I love the unconventional setup & thinking outside the box. Like the guy says, it justs has to last 1-2 laps at WOT, but I think he's on to something.
Edit: Damn, third spring suspension setups and a in the works pneumatic ride hight system to keep the ride hight constant, regardless of downforce loads (low/high speed). These little niches is what makes racing so interesting to me. Thinking outside the box. Id love to have a beer with this dude and pick his brain
holy shit wrx transmission with 1200hp damn what did they expect, thats the one thats made of glass.
Im guessing they had a beefed up sti 6 speed with stronger gear sets, the wrx 5 speed isn't any good past 350-400 tq
Maybe a beef up wrx trans ?? They did say wrx, the Sti trans handles pretty good a little over 1000hp, but then again they’re racing it so... yeah maybe
Damn that thing is cool!
Amazing!
That gives me an idea for Nissan Skyline GT-R tuning and chain drive AWD-why not use the chain that is used on a certain custom 900+ horsepower Suzuki Hayabusa Turbo I found (or rather 2 of them, one for each front axle) and have them run from the front differential to the front axles, similar to the Opel Calibra DTM car and this Impreza. Specifically this would allow the RB26 to be mounted upright (as opposed to tilted, and also similar to the 2000-early 2002 JGTC Skyline) and super low in the chassis for better weight distribution (so low that the standard front differential mounting would not be possible). It would also be more conducive to moving the gearbox to the back of the car (again for better weight distribution), and moving the engine so that up to 2 cylinders are INSIDE the shifter tunnel and the ENTIRE ENGINE is behind the front tire centerlines. This is doable because while a very long engine block, the RB26 (being an inline 6) is also very narrow, the block being NARROWER than most gearboxes.
Pure Tech Car Porn !
I've watched this one before
I"ll no doubt watch it again ;-)
Its a classic.
Shifts like a video game car
I wonder how many non Brits can hear the mother tongue of Kiwis- Scottish English.
70% of the Brits who went to NZ in the 1800s were Scottish. If you listen to certain words between these two , you can hear it.
'Giving' 'Request' 'Unit' 'Head' 'Sitting' 'Head'
If you liste
just a question. how does the R35 transmission handle 1000TQ but is claim to break doing launches?? is it the first gear problem, clutch??
Dude....I know I'm late on the uptake on this one (popped into suggested), but I just wanted to congratulate you for a superbly put together video (if you see this) and also express my adoration to the engineering genius of the owner.
Does anybody know how the car did? What circuit and comparable times for an F1 or anything?
Yes Andy is one clever man, and also a nice guy to boot as a bonus :D
Will be a bit off an open seater, I think he came 4th in his class at WTAC, could be wrong there, but the car has had a lot of Time Attack success back home in Scotland - Taz.
@@hpa101
Many thanks... I've actually searched/found some later information to look through...
The sound of the thing, the level of engineering talent....wowsa
