That was my car, with 93+meth. It got " detuned" to about 675 due to my longevity concerns. Power delivery is incredibly linear. Dyno sheet compared to non meth race fuel one. Noticeably better. This set up has significantly smoother lines, you can feel it on the road.
imo, a must have.
enjoy

 

Great results and feedback thanks!

I'm going to take a little longer and wait for Tom to send me a Champion Tubi exhaust first. I'll do the exhaust switch, meth and R888 tires at the same time.

Should be a blast!

 

I'm assuming my car is the car with the Dyno graph with the race fuel turbo upgrade no meth.

If you're using the car for things other than just driving events 675 wheel HP sounds like a much safer power level than 711.

 

i don't know who's car it is. The risk vs performance equation i currently have is the one I'm comfortable with. We all know how expensive somewhat marginal increases in power can get. It's a personal choice issue for me.

 

Here is my Dyno graph on pump and race gas. Is this the one you saw?

I too could have had the car tuned higher than it is but instructed them not to do that to keep myself well within the margin of safety. I'm not adding any more power.

 

Yes! that is it.
Here is mine.

 

I think you'll love it!
I launched the car on the street by just flooring it moving at about 10mph without traction control coming right out of a turn. I was going sideways and had to lift. I will not disengage it again or make sure the weight is evenly distributed. Caught me by surpriseDid it a few more time expecting it, it was controlable.
Mine reached 711hp with 85% meth + 93. I wonder 100% meth + race fuel will do in terms of power and longevity.

 

Thx for the heads up. I'm pretty good at optimizing the launch on the car. I've got a few thousand launches using LC on my 997.2 Turbo S with R888s on all 4 wheels. I pedal through the launch it's now second nature for me. It's a bit more difficult to launch the 991 with the crap PZero tires but I have fun getting it sideways (on purpose) in first gear.


For airstrip events, the PZero's just wont cut it even with a lot of work on my part. Once the meth system is installed it will be that much worse. So the R888's are a logical choice.


There were four 991's with centerlocks at the airstrip event I went to this weekend and three of them had R888's. They all launched really well.

 

Great! I wish you lots of success

 

Thanks
