Ricky, This is Vinnie, I have the Blown small block in the Dunntech Midengine. I was wondering if you remembered what my fourth gear ratio was. My GPS hit 143 MPH last weekend and we were wondering if the 4th gear ratio with my HP alow such a number. It felt really fast, and the pleminary calculations look like its very possible, but I wanted your opinion, and the actual 4th gear ratio for my S4s. I know your busy, and probably out enjoying the new ride, so get back to me when it convienant. Thanks
I dont think thats possible unless you ran that motor up to 9000 rpm in 4th. The gps must have been off. by the way no i dont have the blower motor any more sorry.
I did a gear ratio calculator online, and with a 4.63 R&P (which Vinnie says he has), and a 1.12 4th and 33" tires, 7600RPM is 142MPH! He said he was close to redline (8000), and did not know for sure how close. It appers to be possible, huh?!
