I dyno'd my 1990 SPG at the SOC and got 232 WHP! That's 50HP more than at Carlisle in May (181WHP).

I did it by tracking down any vacuum leaks, which included some non-working check valves (I wondered why my HVAC valves would whistle under boost) and scrapping my crappy, badly leaking, EGR system the SPGs had. After that, I could easily hold tons of boost!

There was another C900 that got more than 250 WHP.

After seeing some of the shining engine bays at SoC, I am determined to break out the polish myself now!

I have the carlisle dyno sheet at home (at work now). At SoC, they had trouble with the computer getting interference from the car, so I only got a printout of the 232 WHP. No Tq figures, unfortunately.

For Carlise it was 10.5. At SOC, they didn't do A/F, which is a real bummer since I was thinking of changing my 3bar FPR back to a 2.5 bar... but with the massive increase in HP, I worry that the 2.5 might be to low.

Not long enough! Seriously though, I just got all of the vacuum leaks sorted out about a month ago.

I have attached the dyno run sheet from the Carlisle run in May, and the printed sheet from SOC, but SOC run only has the HP numbers, no graph. You can see at Carlise the car had one good pull only. I think that was due to the vacuum issues.
