Money Hello, sound like you have a nice combo already. Can you post some 60ft and 1/4 mile times and MPH. That way we can see what you are doing during the run. Have you tried shifting at different RPM ranges to see if you pick up or slow down? Say 2 runs at 6500,then 2 runs at 6800, then 2 runs at 7000, and then 2 runs at 7200. Kept the tire pressure , timing,jets the same just do round after round. Kept a record of each run. I don't know your complete set-up, Could you tell us what mods you have made to the car? Tony
You still need to think about your exhaust as you can't get in what you can't get out. Bigger is not always better
