The GTM Supercar @ Summit Point

Would mapping the mixture to lean at 0 throttle position stop the backfiring during braking?

Make less use of the shifter, choose a higher gear. ie, when entering turn one, enter in 3rd so you aren't shifting 2-3 in mid corner. Apex's on 1-4 are a bit off, but the rest of the track looks ok. Shorten your braking zones, stop coasting

You know you have yourself a real car when it doesn't have those bitch ass paddle shifters.

I thought a real car had an engine and 4 wheels etc.. Thanks for enlightening me that a real car only shifts your way...

You've got to work on your braking and not coast into corners bro. Heel toe...You'll spin that thing if you don't.

My Brother inlaw bought a Cobra Kit from Factory Five, everthing fit like a glove.
He used a 429 Ford? all I know is I feel safer in a plane..its FAST!
He has built a few others with his friends
he said its easy.

The GTM's are much more difficult though. I've heard they take up to three times as long as a cobra.

whats the top speed on that???

Nice ride. Anyone who has ever raced a car knows that a short / uncorked header exhaust produces popping under deceleration. It's merely unspent fuel igniting in the collector or mufflers, which ever the case may be. Better to pop on deceleration than run lean and bake a piston.

Could it be running rich?
