Running My Gtr On Better Fuel

[7heavn]

Heading back out to WSID next wednesday armed with a decent wheel/tyre combo . On paper from the previous runs the car has a 10 in it with current power (just under 350kwaw on CRD's dyno) . I wouldn't mind having just a little bit more power to make the job easier . The thing is I'm running gt-ss turbos at 1.4bar so I haven't really got any head room here as this amount of boost is pretty much it for these turbo's . I was thinking about getting the car tuned on some better fuel I don't really have a big understanding on the race fuels what should I look at using and what type of gains can be had?? . I'd be happy with a 20kw gain at the wheels just to make my job a tiny bit easier .

C16 and maybe some more ignition advance ? Just taking a wild guess here ...tuner may be able to suggest a few things I imagine

Simply adding C16 won't do the trick. You'd be better off buying one of the many racing unleadeds and having the car tuned to suit. It's not all about the octane rating of the fuel though as some race fuels will burn quicker than pump and require a richer setting on your fuel maps. Only then will they be able to take the added timing and make some more power.

Out of interest, C16 has its place but IMHO it's sure as shit not in a street-driven RB26 like yours. It's a leaded fuel which has implications for O2 sensors, catalytic converters and the EPA, the last of which comes with a free multi-thousand-dollar fine if you're busted running it on the street.

yeh C16 is out of the question . Spoke to Jim at CRD yesterday about maybe tuning the car on vp109 or something similiar for next wednesday but he wasn't too interested in doing it .

I never knew C16 was leaded.... I think Elf makes a decent high octane

yeh c16 is leaded, Martini racing 1400turbo is the highest octane unleaded atm

Find another tuner?

Who do you recommend?.

i definitely wouldnt look for another tuner - im sure the likes of ppl that have been around for quite some time such as paul (dirtgarage) will agree with me that jim @ crd is the beez kneez of tuning

the problem you will also have is that your power fc will be locked by jim which means that if another was to retune they would need to initialise.

run a nos shot that will give that edge you're looking!

seriously though, you want to run a 10 on pump fuel so that you can tell your mates that it is a street car with street tune. thats my angle anyway

100 octane fuel? Shell Issit?
