I'm using a 4 inch.

What kinda of car is this in? My set-up is similar with the 2.5 DP flared to 3" all the way thru & CL W/G by the turbo . Has anyone gotten higher numbers with a set-up similar to this?

good thread! Im also working on something
f22 block(stock sleeves )
95mm crank
h22 head
GE intake manifold
gt35r
precision intercooler
44mm tial WG
50mm tial BOV
it will be done by march
still need: engine management, h22 rods, custom cp pistons,injectors and intercooler piping. looking for atleast 400whp

Drkaccrd

You know I'm looking at your complete set-up - you have the gt35, skunk2 IM, built & sleeved, CL W/G and still only made 350 at 16-17psi!! Dammit thats the set-up I was looking to get, but only I have the built block sleeved an all with a precision sc5027, CL W/G 2.5 D/P tapered to 3" and made 305 with a small *** turbo at 15psi. I was looking to upgrade to the SC61 and touch 400hp but by the looks of it it doesnt look like I cant with that set-up........................ The seems to be in our cases the CL W/G that is holding us back.

MY f made over 300 whp and torque at 15 psi w/ a 38mm wg recirced....... If you have only a 2.5" dp (as i had also)...just make sure you dont recirc (at an angle)till you are into the 3" part of your exhuast...

Originally mine dumped into the down pipe by (before) the oil pan... I picked up a shitload of power by changing this ALONE... With the sc61, you WILL see 400 prob about 15-17 psi ish.... Its just got to breathe

heck yeah man..!! i made the mistake of dumping mine RIGHT AT THE 2.5 inch bend flaring into the 3inch piping.. big mistake.. hopefully fixing that will land me 400 or more whp currently at 360whp... what a waste of time and money making that crappy dp.. LOL steel isnt cheap anymore!!

looking good I have seen this thread a while back.

All these preludes are coming after steve and myself I guess its time for us both to turn it up bigtime this year.

ludesleep

the car itself is no were near being completed to run down a track. I was kinda looking for a local with a car already setup to drop this thing in for next season.

md23vtec

There really isnt much needed to do to the car itself to get it ready to go down the track. You'd be surprised . Goodluck its great to see more H builds hopefully in another prelude lol I wanna see more tanks stiring up **** at events this year

Drkaccrd

thats a nice set-up with the D/P & recirc D/t!! Is that still a 2.5 D/P? Either way that looks freakin sweet.... were & who made it?

Drkaccrd

Drkaccrd

Nice correction factor

trickeng

What is wrong with his correction factor??? It looks reasonable.
