Twin scroll STi 8 turbo on a highcomp. hybride ?

scobbyfouette · 07-08-2008, 12:39 PM

hello there

i was about to use a VF23 on my built just to see what can it do!

But I might give a try with a v.8 twin scroll turbo on my built instead

9,7 @1 ish of compression ration on a 2.5 liter block, using meth

otherwise the rest of the engine is basicly a stock sti v.8

Can i be realistic to expect close to 400 wheel horse power / 400 torque ?

should i expect full boost ( can that thing be reliable at 23-24-25 psi? ) around 2800 rpm ish ?

I remember a 2002 wrx engine with a 2,5 sti short block doing 15 psi by 2600 rpm with a vf 39 an a conservatif tune, no meth ! where doing around 330 HP at the crank

Thanks!

You'll be lucky to get 330whp out of those turbos to be honest.

Just my 2 cents
