How fast is a Heffner TT?

[dbk]

Just for kicks, I thought I'd post this. A stock GT will go 0-150 in somewhere around 17-18 seconds. If you've got great weather and a beautiful launch you might see a 16.8 or 16.9.

Now what will a 2.7 pulley/tune/exhaust car that makes 602rwhp do the same 0-150 test in? With a very good launch and three nice shifts, it will go 15.1 seconds. (as tested by a Vbox in, uh, fantasy land).

Now let's compare :biggrin

In the Car and Driver test they did last year of the first Heffner TT which made 800rwhp (quite a bit improved at this point), they got a less than optimal quarter mile and still ran 0-150 in 12.6 seconds :eek . That is just freaking insane for such a streetable, stock-like car. I've driven that car exact copy and it is just as docile as the factory version. The S7TT they tested took 13.6!

With the current Heffner TT's out there and a great run, I think sub 12 is easily possible.

Am I missing something here? Joes GT ran a 10.4@140+ with the stock blower and a small nitrous shot, correct?

That was on drag tires at a drag strip. I don't know if you've ever seen magazine testing, but it ain't kind, it's on a horrid surface, and done by people that aren't great drivers, on stock tires. The 11.1@139 the C&D rag turned would be a whole bunch faster at a real track!

P.S, all GT speed records are going to be obliterated in a couple weeks. Results won't be public for awhile, but they are going down. Hard.

Are you making a reference to californiacuda?

Nope, though I'm sure he's up to something...

Great thread and Cobra now I know why everything thing I run gives up:thumbsup

Also I am guessing that Joes GT is up to something......I have seen all the posts for several months wondering what ever happened to Joe..(myself included) and none ever replies.

Hmmmmm I am thinking Joe attracted some sponsor type help and that usally means "the sky is the limit"......I bet the 5.4 is somewhere near 6.0 by now.:willy

For reference purposes only, a lucky son of a b*&*& friend of mine has both a Hefner TT Gallardo w/ mid 700 HP to the wheels and a Carrera GT and he said the CGT feels slow compare to the TT Gallardo. Those Hefner TT's are awesome, whether it is the Ford GT TT, Gallardo TT, or the Viper TT. I wonder if they are add TT to my Infiniti FX45 SUV???
