Hi,

I was up at Powerstation on Sat and done a power run with my New Toy. I decided to upgrade from a Cavalier Turbo to a Impreza WRX.

However when i run the impreza it only run a very low 206Bhp at the Flywheel and 99Bhp at the wheels with 107bhp drag. 161lbf-ft torque. with a top speed of 121Mph

Obviously their is a big problem. as the Model code GC8C47D should have 260bhp.

They told me i needed to get it into them for a diagnostic and it would be 2-3hrs @ 75+vat per hour. + what ever parts are required.

I have only had the car 2 weeks and bought a Scorpion Full System inc cat replacement. (as this was developed for the pro drive rally cars i took it, must be good).
Blitz Induction Kit & Blitz Atmospheric BOV.

It has cost me about 1K for all these bits and although i do not mind spending out more. i have been told by them i will probably need the equal length headders to sort out my power problems. but this is not a cheap mod.

If it is essential is their anywhere i can buy one from for a little less £.
I have spent a fortune on the car since getting it as on top of the mods my insurance insisted on a Cat 1 Alarm and a Tracker. so in the two weeks i have had this beast it has already cost me 2K in bits.

I am sure their are a lot of you out their who know a lot about these and might be able to help me.

On another Note i Must add, Every car to run with the exception of a newer uk Scooby. had a masive reduction in performance, even cars that had run on rollers quite recently had seen a masive drop in performance.

 

no offense but if you have only got that much power then "headers" aren't going to solve anything.......................take it to another specialist and have it looked at properly, what were other peeps power figures in relation to their models??

the 107bhp transmission loss looks well odd!!

all i can say is when you get your ra running as it should you will be a happy bunny

does sound like you have another fault like actuater not working etc as above the headers would be a waste of time untill you get it fixed

did they leave the handbrake on when they took your power run ??

 

Put the car back to standard, then try again.
It could be one or more of the modifications you have done to the car that has caused the problem, also what fuel are you running the car on?
Best starting point is at the beginning, work out if the fault was there before you added everything and work off that.

Would probs be worth doing an ECU reset as well. even a standard RA should go like stink.

£75 + VAT sounds a little heavy too

 

pm me where are you based..

 

They quoted me £580 for a service+cambelt!!

 

I have Spoken to Interpro. and will be booking it in with them for a diagnostics, once my baby is here which should be in the next couple of weeks.

I thought the transmission loss seemed rather high too. tbh i was told by someone else that the transmission loss figure is put in by the engineers to calculate the Bhp at the Flywheel, as the rollers measure power at the wheels.



I hope i will be.
I do not believe it has an actuator problem as it boosts and holds 1Bar. Not sure what std is but the fitted guage in my car only goes to a maximum of 1bar. so i guess the boost that i am running is good maybee even higher than std.
I am use to Psi figures and do not know what boost i should be running, i am about to buy a 30psi boost gauge as this is what i am use to.



I did not notice any loss or gain in power from adding these modifications so i do not believe returning the car to standard will make any difference.



I have done a Ecu reset or i believe i have. I was told to connect the green plug under the steering column and start the car then switch it back off, and the ecu should be reset. The engine management light came on when i fitted the filter, i was told to perform this action to reset the ecu, so it would then learn the new air flow intake.

Yes the £75+ VAT is high, Interpro charge £65 + Vat for the First hour and £50 +VAT for each hour there after.



Pm Sent Mate.



Yeh they gave me a service schedule with prices, and they aint cheap.


I have spoke to a local garage that Rallies the WRX-RA, they tell me that the rolling road seems dodgy, and recomend i get another run else where, They have offered to do all my servicing much cheaper. So i have agreed and will be getting them to do any work needed.

Anyone recomend any RR in the South West Area?

Many Thanks

I wouldnt go for there headers ive been caught that way. My car was runnung 272bhp/260lb/ft torque Fitted the headers from the supplier mentioned and lost 20bhp at top end lost 90lb/ft torque at 3000rpm and over the whole rev rang lost an average of 30lb/ft torque. Even tried to get it mapped for them by 2 different mappers. Both said headers are rubbish take them off. Removed them and got all my power back.

 

i wont be using those headers then!
anyone know of anyone else to do a cambelt change around here? chelt/worc's?

 

Sounds as if their rollers were producing artificially low readings : might be worth getting recommendations for other RRs /tuners in your area.

 

It is not unknown for rollers to produce poor readings before spending lots of dosh with the same company for upgrades which produce a magical improvement.

What boost did it actually acheive on the rollers?

It got 204 BHP.
However i have just been told today that their rolling road is out of action due to a software issue.

Maybee they had a genuine problem that they were unaware of.

But i still wont be taking my chances with them.
