N15 GTi Track Car

LOL you impatient lot! i`ve been away for a few days to recover!

First off i went to Greg @ PROTUNER. He`s a cool guy, and obviously very knowledgeable with sr20s.

He did a compression test which resulted in 210 psi across the board, so i`m now throwing my own compression tester in the bin which told me it was 150psi !

The base run with no mapping gave 185hp

40 odd runs later the best peak was 196.5hp / approx 165whp / 162 lbs torque.

I`ve obviously lost some low down power, but 5k+ is insane. He did one run with the limiter set to 8200rpm and it was still holding its power. We settled for a safer 8000rpm limit in the end.

Take a look at this graph. For some reason the true rpm wasn`t being read, as this was the 8200rpm run.
Greg and i were both impressed with the power ouput and the way it was holding it.

I would have liked a bigger catback before the tuning but i`m still happy..........driving the beast is insane! The extra in gear speeds with the higher limiter is nice to have.

Previous in gear speeds: 31.8mph 54.3mph 82.5mph 108.8mph 140.3mph

New ones: 34.9mph 59.5mph 90.4mph 119.2mph 153.8mph

Incredibly close to mine and dales runs – the 200bhp DE still beckons. With I think:

Joe
mongo_tuned *Andy
Patchie
Eddie
and Sam to go.

All strong SR20’s which the forum should be proud of.
 
Are those previous max in gear speeds from a gti box? Im going to put a GTI box in mine as 3rd goes to 105 which is too long a ratio, is 90 about the limit in 3rd on a standard gti box with standard rev limit?
 
Well done Ian, a very strong set of numbers there, and your compression test results are very good too considering the cams in it, (my comp figures are around 170psi across all 4)

I almost died in anticipation here. I started to wonder if you'd make me wait to find out at HLM.:sweatdrop:

Well done.

8000rpm must be nice!
