What low gear you have in the C4?

Chris1529 · 11-03-2011, 07:37 AM

What RPM are you leaving at when foot braking?

Aa Greg says Low gear in the C4 2.92 or 2.75 is the common low gear sets for these. If you are at a stock ratio you can inprove a bunch. My Fox body mustang stoker is simular in wieght and rear gear mine is 4.88 and I run the 2.92 first gear in the c4 has had the best 60' of 1.52 et are 11.97. Do you use a 2 step also?

Any nitrous? Mine is a stock c4, 4.10 gear, 3120 lbs. with me, no nitrous. Usually 1.50 - 1.52 with 2 step at Bandimere runs 11.20's. San Antonio Nitro Jam last spring consistant 1.42's no 2 step. Footbraking at about 2000 rpm and stab the throttle. Ran high 10.50's -60's. Best 60' Saurday morning 1.405. Lots of fun.

I forgot to add with mine I never saw 126 mph. Best was 125.77 mph. I think 132 mph is a lot for that et.

You know, I keep hearing about the 60" improvements multiply. I must be doing something very wrong. Mine picks up in the 1/4 mile the same as the 60' improves.
Never more. When I first started trying to play with mine, after being away over 30 years (no 60' or other incremental times back then) I noticed that when I first tried to bracket race a little. So, I asked my old friend Mike Edwards about that, He knows more about things like that than anybody I know. He asked me "How could ETs improve more than 60' times?". I told him "I don't know, I just keep seeing guys talk about that on the internet." His reply was I needed to stay off the internet. LOL!

A car with enough power to run 132 MPH should at least 60" in the low 1.30s even foot braking it. 10.29 ETs for a normally aspirated 132 MPH car is a bit off. Should be very low tens at least. Fixing the 60' times would take care of that.
