Got my dyno graph today on email so thought I would stick it on here and gauge some opinions... i'm alittle disappointed



The cars a '97 WRX with a rebuilt fully forged 2ltr with the following spec:

Standard VF22 Turbo
3" turbo back exhaust (decat)
Ported headers and matched uppipe
FMIC and induction kit
550cc Injectors, walbro pump and FPR
Apex'i ECU Mapped by Bob Rawle

Comments welcome

 

i had a vf22 fmic 700cc injectors oil catch tanks things rotated top headers full3" systam
boost controler andy carr mapt it and i got 378bhp and 331lbs torque

 

Shocking results. I would be asking questions in the direction of the mapper?

 

that what i got when i had my old vf22 a few years back now but the vf22 was 11 years old as i supsect a new vf22 would make closer to the 340 mark so i would be to disapointed just save some pennys and get a new turbo or a good nick second hand one maybe a vf 35, out of interest what gear box do you have i.e code as my old 97/98 gear box took a 360bhp with 340ft for a long time it was only when i put the 20g that it decided to play up p.s what boost is it running now put the other part of the graph up

 

was your vf 22 a modded vf 22 as my mate gad a modded one which made that sort of power but not a standard one

 

Is that not a run in map, or have you gone through all the run in, and had it mapped again after run in?

 

What boost pressure you running ??

 

This wasn't for a remap, it was just a RR day.

I'm running 1.5bar with std 5 speed box (unsure of code)

I'd disagree the results are "shocking"... I was hoping to achieve around 340bhp but understand its probs a tired turbo.

This was the only part of the graph I was emailed???

 

I would think that is about right. its a 310-330 turbo. and as you said age plays a part.

 

New turbo time by the sounds of it buddy. VF28 would see the power your after.
I made 346 bhp on my VF28 before upgrading to a 20G. It's sat in my garage collecting dust if your interested.

i have heard how the day was run - i wouldnt read anything into the figures tbh

 

I had 320 with a similar spec type r it isn't that bad to be Frank it is a vf22 after all

 

Need data... what gear ?

Why did they not rev the thing ?

What's the fueling doing ?

Where's the boost ?

dunx

P.S. Sounds like someone as rushing the job ?

 

Tbho on a WRX motor peak power is usually seen around the 6-6.5k mark so it wouldn't have done any more power if revved harder.
Does sound around the right mark for a 22 if abit tired as well.
