Re: 393W not running up to expectations
Here is a timeslip from last year for my combo. My car is a 4 speed manual so it is a little slower than a comparable combo with a good working auto trans (at least with me shifting). It is very similar for the first half but my combo is much faster (mph) through the second half. I am running vic jr cylinder heads and a camshaft with similar intake duration but more exhaust duration,lift and a wider lobe separation. I run a 4.11 gear with 26 inch tall tires. Is it possible that you are running out of fuel on the top end?
