My best for my Grand Cherokee is a 15.1 at 89.45mph and that is without exhaust, M1 intake, and Bad O2

I am shooting for a 14.8 with all mods I have now and I am looking for a 13.9 without a new torque converter or opening the valve covers.

 

in the RT...16.11

in the mirada...12.68

in the bottled sebring (not mine but i ran it, with me driving...16.30 (spray aind third gear only)
16.61 (no bottle)
with the owner driving it..15.40 (spraying 2nd gear and up)

 

16.0 at 88mph

My problem is my 60fts suck. Get on it too hard and then I spin through 2 gears. Don't get on it enough and then I'm still slow while I wait for my engine to hit the sweet spot. Hopefully I'll get some tires at least for the front so I can get some better launches in, and knock a few tenths off what I'm doing right now.

 

Coronet ran a 13.34 at 102.74 MPH my first time out. I'm sure it has a 13.0 in it with a little tuning.

 

I wish I knew..My top speed is 40ish, so my math indicates roughly 17 sec 1/4 mile, but from a running start. Standing start would be in the mid 20's. For my go-cart anyway. At some point, we need to take all our vehicles down to sanger 1/8 mile and see what happens.

 

That truck should run in the 15's if it's a Hemi.

 

11.68 at 120.... might a shot at a high 10 be on the horizon?

 

What do you think a supercharger on my 360 would do? Hmmm. Might be interesting.

 

with your compression? i think a supercharger would break internals....

 

I could go with a cam that would bleed the cylinder pressure down enough to run one I think. I'd be better off to just throw better heads and cam at it and not worry anymore about it.
