I want to gather a compilation of people's printouts from rolling road days and their basic spec (head, turbo, chamber vol, boost psi, etc).
Also if you have any drive-ability comments that'd be good.
My current setup is giving me about 25mpg (or 35 if i drive conservatively, but it's so hard to stay away from boost.)

I'm looking for my next improvement on the 998 turbo and want to see some proven results. I thought it'd be useful for others if they were all in one nice place.

So mine...
Standard engine with a R5 T2 and 9psi of boost running through an intercooler. Head has slightly enlarged chambers over standard.

This is my results from the last RR day. Figures at the wheels as the coast down run was not carried out.

998 +0.040", 12g295 standard head, 9:1 CR, cam, 12 psi boost (true), intercooler, R5 T2, Fuel Injection.



Ignore run 3 as it was taken in 3rd gear.

Originally estmated at 122hp at the flywheel, but now believed to be 118hp.

Cheers Paul,
You've missed out the cam type (or is it still a secret?)

998 (Std) SC12 7-9.5 PSI evil suck through 8.71CR 12g295 (33mm/27mm - Turbo Phil ported) Megajolt, no mech fan. Tyres at 30psi. HP measured ATW. Intake temp probably hotter than the sun looking at my exhaust glowing...

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

Can't make head nor tail of that. seems it was taken in 2ng gear.

I've posted all my graphs and specs lots of times, feel free to search them out and move them here. Search for TT at a guess.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Yep is 78 ATW I have no idea about the chart except its measures ATW no cost down.
