Twin turbo impreza type r

[Max M4X WW]

I saw this at Charlie's a few months back, looks/sounds quite mental!

Hadn't seen under the bonnet, which also looks very impressive

[y2blade]

That looks a bit serious

[Killer2005]

Looks fun

[Pumajay]

You sir are nuts!

Love it

Yeah he kindly let me finish it off out the back there

Seen a few pics of this car before, didn't know what was under the bonnet! Very very impressive.

Wow, that looks/sounds great !


Why use the 3.3 engine?, Is it a case of more cylinders, more capacity, more power?...

I take it that the standard engine is unable to produce big (reliable) figures?...


(I'm not knocking your conversion at all, just curious...)

The best setup on the 4 pot gives you nearing the same power I have now but nowhere near the same torque and also takes a fair bit of work with front mounting the turbo on a 2.35litre version of the four pot.
However thats at high boost and more stress on the four pot.
I am currently only running 1.6bar, when I get chance to get used to the current level, I will up the boost further.
Engine should take 2.4bar easy.
So yes spool, power and torque the main reasons really

Any idear what it would run at 2.4 bar ?

950-1000 ?

Well the turbos as a single unit normally do 420bhp on vpower.
I have had 500 from on on vpower with 20% meth mix. That was 1.8bar.
I dont think it is necessarily correct that it would make double at the same boost and fuel.

But racefuel would help lol.
The engine seem very efficent and the gain I have seen at 1.5bar from vpower to racefuel and meth mix wasnt massive so the next engine will be higher compression as it is nearly reaching mbt on vpower.

Mind you the next engine build will include a stroked billet crank to bring it upto 3.6litre
Its always good to have plans lol

Whilst I am in the same boat as everyone else, in that I think this is nuts , I have to ask how much understeer does it suffer from?
With the engine being so far ahead of the front axle line, it's going to be very nose heavy. Have you done anything to offset this?

[marcgti6]

Properly mental - I love it!

I'd probably give a limb to have a spin something like this. Let me know if you fancy a spare leg or something!

[fieldmau5]

Wow, almost seems like you've put in a 911 turbo engine in your Impreza. (Is that actually possible?) Love it!

the only in anger driving I have done was on the run way with it so far.

On the road is doesnt understeer at all and feels like any other impreza.. obviously the cage helps keep the shell ridged. Will see for sure at the sprint I am doing end of May.
I dont think it is going to be difficult to dial any understeer out with geometry settings anyway.

Wow. Fair play, that is one hell of an Impreza.

How many seconds/feet does that 22 litre tank last?

[JollyGrnMonster]

About 5 minutes at full throttle

Noice.
