    Cobra Jet on the dyno

    A friend of mine just bought a 2012 SCJ with the 4.0 liter Whipple. It's supposed to get delivered to my shop in an hour or two. I can't wait to check it out. I'll be sure to get some pictures, dyno sheets and video of it at the track.

    Lambo Aventador sold out 18 mos production

    It'll be interesting to see if this remains to be the case once they start arriving. I remember when the Superleggera came out. Lamborghini said that they were all pre sold but some of them were still sitting on showroom floors two years later.

    GT 200MPH Speed Day/Mojave Mile Update Thread

    That's pretty much how I interpreted it.

    GT 200MPH Speed Day/Mojave Mile Update Thread

    I think you misread that, Soroush. It says special race only engine.

    Ford GT Forum 200 mph Club & Standing Mile Results

    Congratulations to everyone who participated. It sounds like everyone enjoyed themselves thoroughly and drove away with memories, and friendships, that will last a lifetime. This is absolutely what it is all about.

    GT 200MPH Speed Day/Mojave Mile Update Thread

    I would urge you to re read the thread because you have clearly overlooked a few key statements. We certainly did not go directly from celebrating the GT speed day to a vendor telling a member that he’s trying to “justify his set-up to himself or others”. As I see it we went from celebrating the...

    GT 200MPH Speed Day/Mojave Mile Update Thread

    Ed, I'm not sure what to think of this. I am also having a hard time figuring out how you might have gathered the information to substantiate such a statement. TT's don't work as well on road race tracks? A Whippled car will not go for more than a few laps on most road courses without going...

    Heffner TT - On Steroids!

    Kendall, Thank you again for your post and for all of the effort that you have put into putting the GT 's that much more ahead of the competition. It's hard to imagine that over the last few days there were so many Twin Turbo GT owners (and their wives!) driving their cars at over 220 mph and...

    Heffner Twin Turbo V10 R8

    For the past several months we have been working on the development of our bolt on V10 R8 Twin Turbo system. This system employs twin Garrett GT35R turbos pumping out 6 psi of boost which produces an ear to ear grin inducing 725 wheel horsepower which brings it up 225 wheel horsepower from...

    Gauge Issues, new information, please read and respond

    I'll be surprised if the new alternator fixes this issue. At the Texas Rally, Ray's matte black car had a similar charging issue. There was a really nice guy that had an extra GT, (some dentist from Texas), who offered to loan us his alternator but it didn't solve the issue. It ended up being a...

    Honda U3-X

    I just wonder if it will be able to support the lazy 400 pound persons that will likely be riding it.

    Hmm. 100 octane Heffner program didn't add power.. any ideas?

    I'd love to assist you in any way that I can or at the very least answer any questions that you have. If you'd like, give me a call or pm me your contact info and I'll give you a call. As Shelby said, when you are changing the tune in this type of application the primary difference is ignition...

    John Mihovetz [ ACCUFAB ] Modifying my crankshaft

    I know that this is a bit off topic but I have noticed a few people wondering about the possibility of removing the factory balancer with the engine in the car. I have removed at least a half dozen Ford GT balancers with the engine in the car and have never had any trouble whatsoever. I just...

    One of the proudest moments of my life!

    Thanks guys. I would have given anything to have been able to do something like this when I was young but aside from the fact that I don't believe things like this existed, we just didn't have the money. I feel incredibly fortunate to be able to do this with my son. The memories of this will be...

    One of the proudest moments of my life!

    A few months ago I started my four year old son in go kart racing. Since you are supposed to be five years old I figured that we would get almost a year of practice in before we had him compete. The problem was that after a few thousand laps by himself he began to get bored with it. We found a...

    Stasis Supercharger for R8

    Our installed turbo system comes in at 32,000 and produces 90 more horsepower than the supercharger system. Aside from this, the installation has a much more factory appearance though it does void your warranty. Either way though, you'll still have a great car.
