Reply With QuoteVery good for a seb2!! If i did make 155bhp on 13psi what ya think rought estimates would be at 20psi?
183hp with 20psi i think, maybe 21. TTS1 though, not VL7.

WHo knows, its not mathmatical. I would say 170hp would be on the cards.
Over the years at least half a dozen close mates have had GTs and 4 of them had 170hp Seb2s all at ~20psi. Couple old, one brand new built buy a local motorsport engine builders... Its a pretty fixed range of power on Seb2.
youd think a 15bhp gain would be possible with boost gain of 7 psi. Still i need to stop yapping about it and actually get it booked in at hayes engineering.
i reckon it should be feasable.
The higher the power the lesser the effective of a boost increase on the outcome.
On Seb2 with the VL7, you could probably boost it to 25psi and it not make much difference to 170hp. Abit more torque, but not more power.
The rollers i ran Seb2 at there were alot of stock cars on that day, Fiesta ST made bang on 150hp. DC2s making bang on stock power so you could assume it is an accurate result.
If you have ran on those rollers before they'd be the best ones to get a fresh result on.
that is one hell of a turbo
Corsa c20let is definately on the cards for a next car, along with a civic ek9, and integra dc2. Swaying more towards the Honda's though.
