Here's my dyno sheet from the upgrades I had done yesterday at Powerstation in Tewkesbury. I'm afraid I have no clue about these things so if you guys could give some pointers on what looks good/bad that would be great.
It's a MY06 Subaru Forester 2.5 FXT - engine mods are 3" Milltek turbo back system, VF39 Turbo, 255lph Walbro Fuel Pump and Tek3 remap. Unfortunately I couldn't get the upgraded intercooler on so had to stick with the oem one but plan to upgrade asap.

Cheers
Pete

Max power was measured at 317bhp at the engine. Isn't that what people quote as max power when comparing as opposed to the figure at the wheels.
I think the normalised figure takes into account the conditions on the day or something ?

ie based on this chart my max power would be 317bhp and 310 lb-ft torque..
 
Yep - ok I understand that now, many thanks..

My point is though when generally people say , my car does 400 bhp blah blah they are talking about the estimated engine figure from a rolling road, not the at the wheels ?

some good results there Pete.
The intercooler with remap to take advantage will give you around 10bhp on the road I reckon, on the rollers however something like 5bhp??

What made you choose the VF39 and not something like a TD05 could have been a bit cheaper for similar if not better results...?

Thanks all for the replys - very informative ! :)

I used the VF39 for 2 reasons.
1) It's the turbo used on the Impreza Sti with the 2.5 block as
you know and
2) My mate had bought it brand new and never used it so I got it cheap :D

It is absolutely flying though ! I'm just wary of pushing it too hard at the moment until I can get the Intercooler changed ;)
