st170 poor dyno run
Hi, just had my st170 on a dyno and results were crap!! 155bhp. I've heard some engines were down on power but this is dire. I've fitted a k&n typhoon kit and a peco exhaust and that's it.
I've also had ttv racing flywheel fitted, but the dyno shows a massive 41bhp in losses. Are there any issues with the typhoon/peco set-up on standard engines, and do the power losses look similar to other dyno sheets ?? Any comments appreciated. Cheers

could be a fault like the imrc playing up which is very common fault with the st170's
could have a sensor down etc worth having a look at.
they also suffer from cat and lambda sensor faults also check maf unit
might also be worth running it on super unleaded
the kn systems are very good and should of seen some gains above std power
as for the peco unit is full system in stainless steel or mild or just a back box ?
the mongoose/blueflame +miltek systems seem to give good gains of power
if not happy with the car get it looked and set up properly (chipped) etc
each dyno is different to others tho so will vary in results

Typical ST170 I am afraid mate, poor quality control on the heads meant that they weren't being made to proper standard. You can check everything with a fine tooth comb though make sure everything is up to scratch before you start doing anything drastic so just get the car on diagnostics check all sensors are working and everything is performing properly.

I can't figure where you get 41 horses lost, it doesn't matter where the power is measured, if it is on a decent rolling road that can measure run down/trans losses, but have to say they are not usually 170, only seen a couple they were from memory 163, 158.
You should be able to see from the printout if they are massive issues fuelling wise, what did the RR operator say ?
