WOW defintly some major problems....what A/F are you tuning it to on the wideband?

 

[cfisher]

What did you run against?

 

[jasonlee]

a/f is showing in the range of 11.3 to 12.2 or so it varies.... i also forgot to add that i have a 3" intake pipe, and a 3" gm maf with the translator in the "blow thru" setup

i ran against an old ss nova that lifted its wheels off the ground when it launched.. it was pretty interesting to say the least.

seems to be a tuning / driving issue. Your 60 foot should be in the 1.7 range so you are already loosing .3 s right there. Timing for some more tuning and some launching practice?

I wouldn't say it's a driving problem. Even with a 2.0, he should have trapped closer to 110 and at LEAST a high 13. He only picked up 21 mph from 1/8 -1/4. Unless you weren't WOT for some reason, the power isn't getting to the ground. How's your compression? How's your clutch holding up? I'd look at the clutch, that's my main concern. Any problems besides low numbers?

Clutch seems to be pretty good, doesn't feel like its slipping but I am afraid to launch to hard cause I've already broke a 2nd gear, and a center diff.

It does start kinda hard, and idle surges till warmed up and there's a touch of lag but that's the 20g talking.

One thing I do not have is an EGT gauge and almost every time I drive my manifold is at least slightly glowing if its dark out. So I know I need to get an EGT asap.
