MY03 STI PPP Rolling road results.....
Had my car dyno'd twice recently after problems with ECU, its still never made anywere near the quoted prodrive figures....
Anyone ever got anywere near the quoted figures....???
examples of the same model would be helpfull, as i still think there is something not quit right with this car....
My best so far is below

Think that the standard response from Prodrive is this is down to "heat soak". The PPP ecu closes down full power when the temps rises on the rolling road.
Think you'll struggle to get the full power on a rolling road for the above reason.... but might it not be worth a call to Prodrive?
Have you had any other mods done since the PPP?

Makes you wonder about buying a PPP. My sti 7 made 278 bhp with a decat centre and backbox only. My 8 just has a backbox.
I'm sure I've seen people on here claiming 307 bhp from a PPP

Ive seen a standard STI PPP one do 304bhp and just under 300 torq figure at well lane, the dyno bloke recons mine isnt smooth on the dyno...
Ive had conversations with Prodrive on this which resulted in a replacement ECU as my preveouse figures were less than standard STI, they then swapped ECU and it made the 289...

Need to remember that one man's dyno is another mans dinner (sort of!) - my point being that comparing dyno figures is almost pointless. The only way you know what your car is doing is to dyno it at a fairly even temperature, make the modifications there and then, then dyno it again, hoping the temp change is not too much. Given your car was standard at the start, and you know the difference on a chart, you can work that out as a percentage and get a fairly accurate figure. Otherwise, you may as well guess....

Good 'ol heat soak.
Best my PPP ever did was 289 on the rollers. Worst is 261 (less than standard).
Contacted Prodrive, told it was heaksoak.
Anyhow, Tek3 and bigger turbo coming soon

IIRC Traditionally a 'Dyno' the engine is removed are bolted on it and a fluid flywheel arrangement puts the adjustable load onto the Engine. A rolling road Test a whole Car
Hope this helps

I was at G force beginning of year and got 317 bhp from my ppp MY03 Sti
Then again it was running with Decat and filter.... rolling road operator struggled initially due to high inlets...
Still happy with figures I got!

So what's so different about the WR1 that allows it to not be affected by "heatsoak"

Its all very odd....which dyno was the wr1 shootout....?
Think maybe prodrive have tweeked up the cars to make them achive the correct figures.
Were they run up in 4th or 5th gear..?

All the figures depend very strongly on which RR you go to. I know someone who got 302bhp with an STi7 at G-force, and only 290 at Power Engineering. Would probably barely make 270 at power station. Which is right? Who knows, who cares? Look for a comparison between PPP and no PPP on the same rollers to give some idea, but the real thing is how it drives.
