would you be happy with 329.5 bhp and 305 lb/ft from a 93 wrx?
I've spent a long year moding my standard 1993 wrx which has cost a lot of money. I was hoping for a 350bhp car. I had the car on the rollers last week and it's putting out 329.5bhp and 305 lb/ft torque. The guy at the rollers said the car usually runs 0.1 bar under on the rollers so on the road it's probably putting out about 340bhp. He also said it's a very high torque figure for a Subaru.
Would you be happy with this figure? I know it's sad, but I really wanted 350bhp!
I've put a lot of mods into it to get this figure and thinking about it I would have been better starting with an STi.
The mods fitted to the car are:
Walbro 255 Fuel Pump
Nismo 550cc Injectors
Custom Exhaust From Turbo Back, Titanium Back Box
XS Power Stainless Headers & Up Pipe
Hybrid Front Mount Intercooler
Blitz Induction Kit
TD05 18g With Samco 90 degree hose
Apexi Power FC
Apexi AVCR
Datalogit Kit
4 New Coil packs
4 Nre NGK PFR7B Plugs
SX Fuel Regulator
Helix Catch Can
Just looking for thoughts really?

Very similar to my mods (just different makes) on the same year of car. Only real difference is you have the 18g, whereas mine is the standard 90 degree 16g (gearbox preservation 
)
mine has only been mapped to 1.2 bar as the clutch was slipping during mapping. No idea what eventual bhp and more importantly torque will be.
Anyway, to the point. That sort of power on a car that age that weighs just 1200 kg, after spending that sort of money is IMO perfectly acceptable.
I'd be happy with mine at 310/300 (240/225 standard) without the 18g, so for the extra for the turbo, your figures are what I'd hope for.
You haven't mentioned if your gearbox is standard? If you have much more power than your figures, you need at least an sti4 (I think) gearbox at £700+ and your's will be on its limits at the moment.
Being disappointed with your car at 340 bhp, when you wanted 350 is just mad I think
Ah the old sti starting point. I regret that too, but I've left my old WRX sticker on to fool those not in the know

hoping for a power figure is a bad idea as when you put your car on the rollers and it doesnt make it, you spend more wedge trying to make it quicker. different rolling roads and days will have different power figures. !!! if your happy with the car and it drives sweet ignore the bhp figure

nice motor m8,
imo if you think you have 340 would you be able to feel the difference if it was 350? after all its only another 10bhp which equates to about 3% of your cars current output, if it drives well and your happy with that then i'd leave it be unless you are after something extreme,
I guess it is still quite rapid? as has been said, its only a 1235 ish KG car so you will have about 275bhp per ton which is only 10 less than a Ferrari 355! (286/ton) 4 more than a 1999 Porsche GT3 and more than any road going M3 variant
you cant grumble at that mate

Your car looks mint, especially the tidy bonnet; you're running well over 300bhp in a 4wd road car, what's not to like. It's a slippery slope chasing a particular power figure tbh. If it feels right to you then be happy with it! Of course, if it feels gutless, then that's another matter.

Nice Car,
Could your disappointing rolling road figures be related to the intake temps during the Rolling Road run? With no bonnet scoop, what precautions have you taken to keep the induction temperatures low?
Just a thought

Wow that's a really great looking car bud...
It's so easy to build an image or aspiration in your mind..but you really shouldn't be disappointed.
Yes of course if you were to do things again then perhaps you would begin with a different base -sti-
BUT what you have done is create a superb example of WHAT can be achieved. Perhaps its the same as any owner maintaining an older style car money is spent improving its appearence, interor or performance and in reality the money could just be spent on a NEWER car...but is that what car ownership is about...??
I similar to you have 'only' got the WRX yet am ploughing money into the car to 'improve' it...
Have fun and enjoy.....

Ian,
I realise he is running a fmic........ but if the blitz induction kit is mounted within the engine bay and there is no means of feeding cold air he could be seeing induction temps while on the rollers of 30-40 degrees above ambient.
In those situations the FMIC will be hard pushed to cope and charge temps will be higher than ideal.
Heat management is very important
Just my opinion of course

if i recall correct,Andyf used to run his scoop backwards when he had the front mount on his car last year.... i presume to allow the engine heat built up in the engine bay a route out? with no scoop the heat generated might well affect the performance,air flow through the engine bay is worth looking at.

...tbh the induction side of things didn't occur to me, what with the ever increasing number of inner wing mounted kits now available.surely removing the scoop shouldn't make any difference to air flow across the engine because its not designed for that purpose?

On the road, then yes, I would of thought it could be an issue, Subaru put the scoop their for a reason, That wasn't just to feed the top mount intercooler but also to keep the turbo cool because
of it's position.

The problems with Rolling Roads are that we all make sure that are cars a upto normal operating temperatures and then let them stand whilst the cars are strapped down, During that time, underbonnet temps are rising all the time.
Unless specific measures are taken to combat the high intake temps, i.e. cold air feed, CAIK or heat shield for the induction kit, cars will not fulfill their potential on the rollers.
All IMHO

To answer a few questions...
When the car was rolling road'd they had the bonnet up. They also had two 80 mph fans blowing onto the car. They also put something in place to separate the induction kit from the heat of the engine bay.
On the road with the bonnet down, the car does get a little hot underneath. The rubber trim from the bonnet that closes on top of the light has been removed, so I get a thin flow of air in there. There is also a big hole in the wing where the FMIC pipes come through.
Saying that I could do with sorting something for more cold air. I was thinking about getting a vent of some sort in the wing. I've not really worried about it much as the car does run really well and Andy has been happy with it on the two times he's mapped it.
Below are a few more pictures of the car. Someone PM asking for some.
Cheers

I am open to comments on how I can get more out of the car. I really would like more torque rather than bhp.
