Building a 2000hp GTR

[Mook]

I'll try and keep this thread updated as the NAGTROC gets updated.

GT1R Shop GTR Rebuild, shooting for the moon! - R35 GT-R - GT-R Life

We've been a little quiet and a lot busy here at the shop. Finally have things coming together enough to share. I'll keep this thread updated with progress pictures between now and TX2K, which the goal is to be finished for. We will have lots of new things and no testing time, so I don't expect to set the world on fire at TX2K, but I do expect to make some noise for 2015. addleshift:

The build is based around our GT1R 4 liter engine with some additional block stiffening that we hope will hold us over until our billet block is ready.

The turbos are from Forced Performance, they are HTZ4505's with a couple special touches. As you can see in the pics we will have turbo shaft speed monitored along with exhaust backpressure and in the near future wastegate position on the TiAL 60mm wastegates. We'll have a very good idea of what's going on and why, and where improvements can be made. These turbos are good for a comfortable 1200+hp a piece, so running the car around 2000hp will have the system in a very comfortable area with plenty of room to go as engine development catches up.

The intercoolers are built in house using Garrett air/water cores.

The headers are built in house using 321 16 gauge stainless tubing and Burns Stainless double slip fit collectors. The downpipes and dumptubes will both come up through the hood for TX2K and the exhaust will run back under the car for Texas Invitational. We've got an AMS carbon hood (beautiful piece) for the drag stuff with the downpipes coming through it and will use the stock hood for other events where we have to run an exhaust system.

The dry sump oiling system is a kit that Magnus Motorsports has been working on and will be available for the public very soon. There are many advantages to a proper dry sump system and at this level it's almost a necessity.

Race Spec is building a nice mil spec engine harness for the car, will have a firewall disconnect in the center of the firewall and then all tefzel wire and Raychem shrink and boots from there out.

Anyways, a few pics for now and i'll keep info and pics coming as things progress.

Shiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiit. I want that.

 

[Spivitz]

So bad ass

 

[OffshoreDrilling]

looks stock

Shiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiit. I want that.

Me too. But someone else needs to fund it

id kill myself.

 

[blck10th]

id kill myself.

But what a way to go!

The thing I don't understand is, why can't a grand prix make that kind of HP? I mean, it's 3.8ltrs...

 

[Primalzer]

How many maxed out 3800's would it take to match this 2000HP? 3?

 

[10sec]

Yea, like 2.7-ish of them. But in all fairness, I'll bet you could get all 3 motors for less than a set of pistons cost in the OP motor

 

[YoushallgoFo]

how many 700hp 3800s could you make for the price of 1 stock vr38dett

 

[Turbocharged400sbc]

personally...we're figuring on not needing more than two....

 

[10sec]

Well...

~$400 for the motor
~$600 upgrades to handle the power (cam, head gaskets, head studs, springs, etc.)

$1000/motor+turbo kit capable of the power = ~$5000

Surely you could do it cheaper though.

So 2 or 3?

 

[Turbocharged400sbc]

Could build 3 442s for what that thing costs
I wonder what its final weight will be

Some comments -

The block is filled with magic pixie dust and hundred dollar bills. Hope it works.

Yes, I will be running methanol on this. Primarily because the radiator has to be undersized to put the turbos where they are and you can get away with that on methanol.

This will never become a package so that point is moot.

Methanol has lots of advantages in a race car, but the main one here being the small radiator requirement when running methanol.

Going to a lesser fuel and adding a bigger radiator only has disadvantages. With a build like this the goal is the best option in every department and for a 6 cylinder engine making over 2000hp, there's no question you want the best fuel you can use. In my opinion that is methanol.

Yes, I believe AMS is using an ethanol blend.

Methanol has a huge fuel demand and requires a lot of maintenance, but i've got that covered. I'll be using 12 ID2000's at 130psi differential pressure, so a total of ~7400cc/min of injector PER CYLINDER! haha

I have a big mechanical fuel pump from Kinsler, a -16 in/out pre filter from Peterson Fluid Systems and a 10 micron post filter from Moran.

thats.....thats a lot of fucking fuel

That is going on the wall. Awesome Picture!

 

[SinisterSHO]

Dem welds

 

[IDAFC21]

Now that is what you would call a functional work of art.

 

[Mook]

2160hp

 

[99PONTIACGP]

Boner. ACHIEVED.

 

[Thirdgen89GTA]

53psi damn.

But that dyno is just RWD. I see the half shaft in one of the pics, so I assume they kept the AWD.
