OK, it's been nearly a year since I started this post. I'm a patient man. Is there any progress?
NOBODY has broke into the 13's with an NA car, (on just the motor alone) that I'm aware of.
The Crossfire has been around for a dozen years now. There have been all kinds of H.P. #'s tossed out there, what with CAI's, tunes, injectors, pulley's, headers, things that you would think (in the right combination) should be enough to put the XF thru the 13 sec. barrier, yet nobody has laid claim to the bragging rights. Oh sure I've read a few post's over the years where some people claim their cars are "capable" of running 13 sec. 1/4 miles, but unfortunately, talk is cheap, and calibrating a butt dyno is not something many people want to do. Time slips, and (better yet) video speaks volumes.
I know, lot's of people are going to say, why bother? The NA's aren't drag cars, let it be. If you want to race, get a 6. Well to those people I say, car enthusiast don't want to hear that. Every car can be made to accelerate faster and that's the name of the game. Besides that, anything that makes an NA perform better, would make a 6 perform better. Right?
From day one after purchasing my Crossfire new in 2005, my intentions was to install a lower gear ratio. I soon found out there was no easy, inexpensive way to do it, but I figured surely in time somebody would come up with the right formula. I've always said it's going to take a much better gear to see the 13's. How much longer is it going to take.?
