The results are a bit confusing. Unfortunately I didn't dyno it before I put the Stillen CAI and UT Z-tube on. With this combo I got 278,5 crank, which is almost what stock should be and is not bad but the rwhp is a bit puzzling - 207rwhp. This would mean 26% power loss on drivetrain - a LOT!. As far as I know this should be around 20%. What do you think?

 

That seems really low. What kind of dyno were they using?

 

How exactly did they measure crank HP? Did they pull your motor out and strap it to an engine dyno? If not, then they are probably just basing your crank HP on your RWHP (using a multiplication factor probably).

 

The dyno was maha LS300. I don't if it's known in the US.

The crank is measured with the factors you gather adjusting the dyno to the car. In Europe however the bhp is the number that is commonly used and measured as opposed to rwhp in the US, so the rwhp on a dyno here is rarely shown. In this case it was and it wonders me why it is so low.

 

Sound like a diff setup, things get wierd in Europe.............Not too bad, ive seen worse.

 

What do you mean by diff setup?

Seems rather low. Did they do the dyno run in 5th gear? I recall most people getting in the 220's stock. With a manual, the drivetrain loss should be around ~18%.
