Hi there,
Just had my STI V2 555 run on a rolling road. The results were a disapointment althought i was infomed that the figures were normal:

Here they are:

Wheel power - Pwheel: 169 BHP
Engine power: Pengine: 240.8 BHP
Max Torque at 5890 RPM 153.4Kmh

These figures are well down on Subaru's spec of 275 BHP.

It even more disapointing as the car came with a sports exhaust and and new HKS triple layer dry filter. I was (maybe stupidly) expecting more than 275BHP.

Ultimately i would like to bring her upto 320BHP and was hoping to do this for about 1000 pounds. Is this achievable??

This is the first time i have owned a scooby and the first time i have delved into the world of tuning.

Am i justifed in being disapointed

Your advice will be greatlly appreciated.

Regards

where was it rolling roaded ?
what was the torque figure ?
what petrol do you use ?

remember the BHP figure quoted was on 100 RON fuel and when the car was new
it's 13 years old now.

to get it up to 320 bhp you'd need a full decat(unless it already has 1 , check down-pipe) and simtek ecu , turbo, intercooler,gearbox and injectors, if in good condition, are good for 320 bhp. also consider an organic clutch,like exedy.

 

Thanks for your reply an sorry for delay.

Torque was 275.3 nm. I relaise to in standard spec to achieve the full 275BHP would be unrealistic from a 13 year old car, but is 240BHP accepable ? I was hoping someone out there could tell me what their figures were llike so i could compare them.

 

Torque is well down, my near stock Foz (UK model) made 320Nm, yours should be nearer that in lbft!
