enjoy the car!

Only dyno'd on the race fuel.

I ended up with 4 maps:

-6: ??octane we get in Malaysia or Thailand. This could by 89-94 pump octane

0: Singapore 98 octane (or VPower from Shell in Singapore)

+4: 98 octane (Singapore) + HKS DHOB additive.

?? HKS Drag Race Fuel - Can only be set by HKS tuner on the day.

I probably should try a 98 octane run to see what we get.

I'm curious to see how much additional power race gas adds... or rather the amount of extra power you can tune for with race gas.

We may run a dyno on 98 octane pump fuel after next oil change. Sorry not in a hurry since the car has been in the shop or rev limited soo much since mid-December and I am just enjoying the drive for a change.

Did anyone see a dyno report on the SCC car?

Seems their link is no longer up and it is not on the Cosworth site either.

Is not going to teach Eric Hsu about engines. Or, maybe you're just dumbing it down for the forum and you're really a top race engineer in disguise. Either way, top form

Ummm...no, unlikely.

LOL, "(will the) the gains from a rear end mainly present only at the low end?" Yeah, the final drive magically changes ratio on the fly.

Very nice work, I missed this thread first time through.
