Just curious to compare the manufacturers specs as compared to actual figures.
I know that some of the figures coming out of Japan can be considered dodgy at times (EvoVII).
Anybody?

 

I think JGriff did at the last PE rolling road day......

 

Ok thanks.
JGriff, care to comment?
(or anyone else for that matter)

 

Popped into PE yesterday, and saw some dyno plots of a couple of STI 7's with PE exhaust system. They didnt have the before plots, but with the mods the STI's were putting out 300bhp and 275lbft.

We also overlayed my old STI 5 with same mods except for no cat (PE system still has a cat in the downpipe). My STI 5 came in little earlier, but the STI 7 really hangs onto the power where the old shape took a nose dive. Peak power in the 7 seemed very close to the red line.

My STI7 (UK) went on the PE road when it was very young. Had 264 bhp and 248lbft. The interesting thing is the torque. It peaks at about 4000 rpm and then falls right off, which you can tell when you drive it. There was a japanese import the same day and the tester was surprised by the difference when he tested the cars as he thought mine was an import as well (it's debadged) so it's obviously noticeable.

 

Chins any idea what the Sti7 was boosting to as decatted ones have been spiking to 1.7 bar.

 

Whoops just reread your thread the PE exhaust still has a cat in it.

 

Thanks for the replies guys.
Any others with a run-in Sti?

 

Sorry guys mine has been nowhere near a rolling road. Jonathon are you saying that you have modified your and been on a rolling road?

 

Sorry JG, must have been someone else @ PE.....

 

300bhp & 284 lbft with PE T75 system only mod. (incl. sports cat)

Was dyno'd @ 311bhp & 293-ish lbft prior to restrictor being fitted

Like Chins says, peak power @ 7450rpm.

No major overboost problems like some STI UK owners. Peaking @ 1.3bar, then level at just over 1 bar.

Mines not modified. I was probably looking at Pauls Plots. I had modified my STI V, and was comparing the STI 7 against it.
