I am about to do a turbo upgrade so I got a base line done.

mods:
ej257
stock wrx heads
sti pinks
vf34
up-pipe and txs turbo back.
ecutek.

I am upgrading to a pe1820 clone with pe650 injectors. Hopefully the top end will not fall off so much. I know it's going to be quite a change to loose some of that low end torque.

its those stock WRX heads and cams that make the power fall off like that too.

that drop off sucks, at red line you have such low hp numbers!

makes me sad cause i have something similar (mod wish) never dynoed it.

The power definately falls off early . But then again the power starts about 800 rpms sooner than the setup on a 2.0. 300ft lbs at 3400 rpms makes for a good autocross setup.

scoobyimpreza with your vf22 the power shouldn't drop off as much as mine. I bet your car is a blast to drive.

haha, its alright right now.. well see how it is next week.. i get a RS tranny/rear diff and hopefully new injectors and alky? THEN dyno time

haha anyways hows your car? loving it? also very true on the statement you made about the Hp.

edit. NM. Didnt read the first post carefully.

Start looking for a tranny, and no an rs tranny won, t be good enough. Hopefully will get enought time this weekend to put in my newly aquired 6-speed and r180 diff , so for me now its time for a bigger turbo. my setup is very similar exceot I,m running a vf 39 at 18psi 310whp 318tq. good luck with the mutt motor, their the best. just like dogs

We can compare numbers hopfully sometime in the future. I am in the middle of a EJ257 w/ V7 heads + 6 speed. Should be done in about a week, then tuning!!!! I'm sure i will forgot some small part i need......

I just installed a Deadbolt vf22 and got it tuned at TopSpeed. I am very happy with the turbo and the tune.

The chart is of both my old setup and the new. This is a much better combo.

cannot see the chart

OMG I cant wait to see what mine does

Going into shop May 9
Getting

2,5 block
CP pistons
stock wrx heads
Crower stage 2 cams
my vf22-P&P (for now)
sti pinks (for now)
RA gearset
Clutchmasters clutch (70% higher rated than stock)

I figure with my cams, if you made 313, I should easily be in the 330+range, with boost not falling off as much.
IN about 2 months, I am going 850cc injects and a superzilla 49 (maybe 52)
Looking to make 375-390 range...


What are your duty cycles like on your pinks? WHat peak boost are you running? WHat is is tapering to???

On pump?

On pump?

yup.

I am thinking it should be possible as my setup, without the cams, with a 20G makes around 350 from what I have seen. And what I have seen of the results from doing cams is around 30whp once tuned.

Davenow ,

My vf22 has a wheel ugrade and port and polish. I am now running PE650's and my duty cycles are in the 75 - 80% range at only 17lbs. I imagine the pinks would be very close if not maxed. I think the higher compression and the stock heads are limiting what boost I can run.


I can't wait to play with some c16;)

what does a stock STi or a WRX make on this dyno?

Get the heads P&P. If there off why not..... From what I've heard the stock heads are quite restrictive.

wait. so that graph of 300 + is that with a VF-22 or a pe1820?

It's a Deadbolt-reworked VF22.

getting better numbers, but your low end suffers :( TQ doesnt tapper as much, but seems as if your HP tappers more?

Low end suffers? I am passing my peak torque within 200 rpms and holding it a lot longer. The 34 to that point was a smoother transition where as this turbo hits harder. The car is a lot more fun to drive with this combo.

oops. double post
