Our Racepak computer automatically gives us a Engine/Drive Shaft RPM Ratio reading all the way down the track.

We know our current converted is way too tight for the Nitrous HP we were using and have just added another 200 HP to the new fogger system.

I was wondering that other successful TD cars have for a E/DS ratio in the lights.

Thanks...

Non successful but mine can be as loose as 9% or as tights as 3% depending on the tune up. 6% is my normally reading.

Mine is just a little over 1 % at stripe

4% for me - However I'm not successful.....yet
