I have 430 Gears that were installed way before I put on my Vortech SQ and was wondering if I am hurting my cars performance with that gear now that I have a S/C. It seems to be but then again I tear out of the hole like a rapped ape so maybe its just that I need to get use to it? Its mostly a street car and have yet taken it to the track since the SC was installed 2 months ago. I loved the feel of the 430's while I was NA. Now I'm not to sure its the best gear for the street. I thought that I would loose alot on the higway but it seems as if I really didnt and pulled past my friends Pullied 03 Term 4 times from a 40 -50 roll. Yes he can drive so its not that he sucks as a driver or even missed gears. Anyways anyone know if I can just get taller rear tires to make up for the gear or should I drop down to 410's and be done with it?And if so what size tire should I get. Another Q.. Do you really loose HP when you step up in gear? I dynoed my car before the 430s and again after I had them installed and to my surprize I lost about 9 RWHP and matching TQ. My Tunner said this is normal. Is it? I just want to make sure that my car is running at full potentional with the right gearing. With that said I do plan on going to the track this year as I did while I was NA. Just have not made it there yet Thanks for any help you guys can provide
Drop to to 4.10's. What did your car run. My 96 ran 12.50's at 114-116 with 1.8-1.9 60 footers. Check sig.
4.10's are perfect for your car. I also trap in the mid-high teens right around 66-6800 rpms. 4.30's will make you shift to 5th or may tempt you to bump the rev limiter and cut off fuel in the 1/4.
