Is CAM 2 100 octane gas okay to use on a heavely modded 911 turbo, Or do i need to look into something els. Does anyone trust thoughs over the counter octane boosters.
I have looked into VP gas and I'm alittle confused. I see that they offer many different octane levels. Can anyone tell me which would work well in porsches? I was thinking o f geting some motorsport 109 which is unleaded and 109 octane. Any help would be great.

 

Don't use octane boosters!!

MS109 would be good if you have catalytic converters. C16 would be good if you don't have catalytic converters.

 

109 is the best you can get from what i was told, big difference also.

 

also depends on the mods. 109 is unleaded and the c16 is leaded some cars cant use the leaded.

 

will the c16 screw up any of the o2 sensers

 

Leaded fuel will cause SERIOUS issues if you have cats. They can catch the car on fire, from what I was told... Stick with unleaded fuel unless your car has been modified (both hardware and software) to use it.

VP is your best bet for buying barrels of the stuff. I looked into getting some 100 octane unleaded for my car, but decided I didn't want to deal with storing it at the time...

VP - MS109 is very popular fuel and responds well to boost. MANY tuners use it. C16 is a little better, but comes with a some penalties, such as cost and being leaded, which will quickly kill your O2 sensors.

 

Isn't there any good octane boosters out there?
i thought Lucas was good?

 

Octane booster = Band-Aid.

You have nice car with exceptional performance, spend a couple bucks and make sure it gets the right fuel.

 

Does anyone know any local vp gas dealers near queens new york?

 

Go to VP website and call them on Monday, they can help you.
Also Sunoco GT260 PLUS (unleaded) works well for high boost applications.

 

In Las Vegas we have Rebel stations which sell 100 octane "competition" fuel for $5.99. When I got my GT2 I began to use the stuff exclusively. An interesting thing happened. I have the GMG exhaust with the flared tips. After each outing I would take a damp cloth an clean out the tips so everything stayed shiny. At first, there was a decent amount of black soot with some heavier black deposits. Over time, as the 100 took hold through the engine, the deposits have gotten less and less noticeable. Also, my engine noticebly ran smoother. I don't know how to explain it, but as it stands now my GT2 runs flawlessly and my flared tips stay clean for a really long time compared to when I first got the car. I'm sure the previous owner, who luckly only put 1800 miles on the car, used crap gas. But I can attest that 100 octane does make a very noticable difference.

 

+1 the sunco gtplus stuff is good for UL... i am running sunoco supreme 112 on a catless setup at $7.30 a gal delivered it a good deal.... o yeah i tried the octane booster thing.. not good i now have a built bottom end

My car only has an ECU reflash set for 93 octane. Is there any advantage for me to put 100 or 110 in my car at the track?

 

ONLY if your pump gas tune is too aggressive and it is retarding timing. Most people "mix" a little fuel in with their pump gas just eliminate the POSSIBILTY of detonation on maybe a hot day or a heat soaked engine.
