What is the reasoning behind running the R32 head?

[b5s4tt]

looking good!

[bernB5]

dude.... 45r? is time attack no longer a priority?
insane, but so sick

[onemoremile]

Seems like the perfect engine to do an equal length twin scroll. It would have been relatively easy given that half the runners are shorter than the others.

Also wondering why you guys didn't use the R32 block and R36 crank to make a 3.4 liter. Even Shimmel and the boys take the old block to 3.0. Quicker spool, lower boost threshold, and better throttle response.


Anyway, it sure looks like a monster.

[MultiAudis]

oh god yes!!!

[coleA4]

I think I can fit my head in the 45r

[mike-2ptzero]

I wonder if they are going to get someone that has more drag racing experiance to drive it this time if thats what they built it for.


BTW its about time you guys put CF fenders on that car.

Well to do a twin scroll manifold on a 6 cylinder they would need to have 3 runners on the front part of the flange and 3 on the back side. They would run into issue with room plus the T4 flange is much longer then it is taller, which is why they have 3 on top and 3 on bottom.

[ILoveT]

I sure hope they are going to get someone that can actually drive that thing if they built it for drag racing.

It's obviously built to be a grocery getter, I mean look at that turbo. Teeeny.

[20vpower]

wowza cant wait for some vids

Thanks for the compliments, glad you like it

Just to address your questions, we are under a severely tight timeline on this project, basically everything you see there, including the motor internals and build, have been done in under 4 weeks, and the car needs to be running in the next 2 weeks, all while running 034, doing tons of service and having a full customer fab schedule. We would have loved to play more with runner length and tuning of the header but the time is not permitting, this is something we hope to do in the future, but I'm more than confident this current design will have NO problem delivering a lot of reliable HP.

We stayed with the 24v block as it offers much more cylinder wall thickness than the 84mm bore of the R32, this motor will not only be heavily boosted, but heavily loaded in full race conditions, it is worth the extra strengh and reliability to sacrifice 10% displacement. This motor will make its power with boost and revs which its very well suited to do.

Thanks again for the interest

Nice to see you on here Javad, hopefully youll stick around for a bit... Btw, this project makes my dads B6 you will be building soon look a little less impressive haha

[034Motorsport]

Awesome, but I dunno, that is still one of the most favorite cars we've helped build

[317ssayzarc]

Doing air to water? Think your going to need a bolted compressor outlet :D

[Wizard-of-OD]

Larger intake ports

3.2 blocks produce hair line cracks @ the bottom of the bore when under alot of stress.A 2.8 block is much better suited for the job and no need for stroke....we have enough displacement.

sell your supra and skyline.There is a new big boy in town

that may be a hint

[A4Rob]

Nice work guys. That car was a monster, now I am lost of words to describe it.

[Nebone]

I hope this performance surprises people even more than the old setup. 034 should be the new overhauling TV crew.

[djwimbo]

Holy mother of god.

That's exactly what I said.

... Then I added, "It's about damn time they put a 24V on that thing!". That's what I wanted in the first place.

Twin 044 pumps, 630 + 1000cc injectors, BAMFT, only the best SEM, ... you guys better strap this thing down tight on that dyno.

Curious, what's the 90* AN fitting going in the back of the trans for? Cooler w/ an external pump?

EDIT: What #'s did you end up w/ on the 12V? I remember a 600+whp dyno pull on YouTube, did you end up making anything more than that one?

[chris164935]

So, the turbo fits without any modifications to the hood and/or frame rail? How big is the down pipe and does it clear between the body and the transmission without any modifications as well? I am also dying to see some pictures of how you guys are routing the intercooler piping and if you're going air-to-air or air-to-water...

[big_greasy_taco]

Good lord... that is a monster. That turbo is bigger than my head!

[Bic-Ball]

lol is the turbo being lowered in on a winch? thats awesome

[034Motorsport]

That's exactly what I said.

... Then I added, "It's about damn time they put a 24V on that thing!". That's what I wanted in the first place.

Us too, but sometimes you have to strategize with the budget you have, AAA VR6 motors are practically free, the 24v took some penny saving

Yep, tranny cooler, our trans has a pump built in.

648whp at the Eurotuner GP 2007, 42psi boost, but the 12v is such a limited tuning platform for real big power, with almost twice the flow in this head, we're looking forward to some significant power increases as well as a much broader power band **rubs hands together, pining for the moment he can tune this beast**

[034Motorsport]

Yup, weights almost 60lbs, it gets tiring with one person!

Pretty much "fits", yes. DP is full 4", it touches in places but the engine is solid mounted, not a ton of room down there though. Intercooler is a massive air-to-air, see:

[djwimbo]

This is probably one of the bigger displacement big turbo cars you guys have built(to my knowledge), I'm glad you guys are stoked about it, not afraid of it.

Any reason for not running a tangential?
and is that a stock radiator? Are they good enough for a 800+hp car?

[034Motorsport]

We're not really afraid of tuning cars, its what we do for a living With a # of engines in the 4-500HP/L range, this one will be par for the course.

Turbine housing? We are...

and is that a stock radiator? Are they good enough for a 800+hp car?

Yes, for now, we'll likely upgrade to an S4 front core support and custom radiator at some point, but for time attack duties, the smaller A4 radiator has been fine for 3-5 laps max.

that's still pretty amazing considering it was engineered for 150-190HP engines that usualy dosent see past 4.5K rpms , are you even still running some off the shelf coolant?

[ricebeater]

that turbo is big enough to eat a baby!

How much would this thing cost to replicate?

[034Motorsport]

Yes, they certainly have plenty more capacity than is needed, we commonly run them on heavily tracked 400HP A4's no problem. We run water and water wetter only, no coolant.

[034Motorsport]

No 1kHP+ capable car is cheap to build, hard to say but its a good chunk of change, the labor alone will be the biggest thing in a build like this, to do the work and install yourself would save a lot of the expense.

[Kyle H]

Are you guys still running the stock transmission (minus clutch), driveshafts, axles and diffs?

I'm just curious if the stock drivetrain can really handle all of that power.

[biketsai]

I was looking on their site earlier, and I think they are running stock a4 axles, and an s4 driveshaft

We were up until the Long Beach Grand Prix, we are now running B5 S4 front axles and front uprights, B5 S4 drive shaft with Stasis 01E short ratio trans. An 01A would not hold up to these power levels on track, in our experience, over 350whp seems to strip teeth off gears (not drag racing, but where uneven surfaces and turning are involved). Stock 2001 A4 rear axles.

That bolded part made me laugh, nothing like good ol' drag racing stereotype coming true.

Is this new car still going to have the low end for a time attack car with the gt45 (i'm assuming no)? What direction are you guys planning this car to head with the new setup?

Can't wait for the dyno video!

[deadleavesdie]

dear god that is a massive snail

[034Motorsport]

Like many of the cars we build, it will be dual purpose, with two or 3 different turbo setups for different use, a GT45R would be a poor choice for Time Attack or road course work, so a 35R setup will be used for those sort of events

C'mon now, I heard it was nothing but hammocks and Coronas in that shop. Something about a massive delivery of limes...


I totally understand the budget and time crunches. Real life has a nasty habit of getting in the way. It looks like you guys built one hell of a car there.

The 24v head is a major upgrade from the 12v. So much so that it hardly needs any head work at all other than proper cams. I can't remember for sure but I think it was Schimmel that put a ton of work into a head and only got 8% more flow.

I'm sure you guys have a ton of connections but if you ever need anything VR6 specific Chris Collier at C2 Motorsports in Louisville is a great guy and has some deep roots.

Now I've just got to convince the wife that buying a 2002 S6 and sending it to California for a big turbo VR6 is a good family decision. She'll come around eventually...
