let's talk about G

Yesterday I measured lateral G and braking G with Dynolicious on my iPhone. My max lateral was 1.08G when hardly accelerating on a ramp... On a 62mph-0 braking, it was 0.99G. Does these numbers seems realistic?
My 1/4 mile was 15.61, a little slower than my official track time 15.40

Those with BBK, how many G are you reaching? And how many lateral G our cars are capable to reach?

i question the accuracy of a iphone dyno.... maybe they are spot on, i don't know. heard lots of things about them not being accurate.

Your lateral G is fairly meaningless, considering the conditions. You need a proper, flat skidpad to get a meaningful measurement... And just FYI, a 997 GT3 (one of the best handling production cars in the world) with Michelin Sport Cup tires can only do 0.98G.

That is why I asked!! Also, I was not pushing it to the limit, It's why I thought those numbers were very High...

About Braking, Someone with BBK can compare with me???
