For what it is worth
Certainly the associated cost plays a role when considering either project however the focus IMO should be driving style and the desired outcome.
The supercharger whether OEM or Whipple will produce the low end grunt; now in the case of the Whipple the grunt becomes extreme and enjoyed by most however by design they will not play as well on the big end
The TT will feel IMO softer and not as strong on the low end however once you past the 3500-4000 RPM she feel as if the afterburner just kicked in.
If you enjoy having stump pulling torque from down low and spend most of your time in the lower to mid RPM range then the Whipple IMO is the only way to go however if you want the big end power and speed then the TT is the ticket for you.
I like them both however remain in the supercharger camp because I enjoy the instant low end.
Now having shared this for some the combination of the supercharger and the TT will become the best of both worlds.

100% it all completely comes down to the end goal of what the customer wants the vehicle to do. Not all combinations are for all GT owners.
That is exactly why all of us are out here trying out different stuff :biggrin

Bragging rights?
And not to rain on anyones parade, and it took me a while before I decided to write this - None of this matters because our options for aftermarket tires SUCK!!! Power without traction is not much fun at all. - AND dangerous if you are not careful.......
For me personally, it comes down to this; I absolutely love the added power the Whipple gives me at freeway speeds, but I really miss first gear shifting into second gear with the stock SC. I think the engineers at Ford dialed the car pretty well when it left the factory. Now I have to retrain my foot:willy:willy:willy
Can you say driver selectable boost control.....

Why yes I can, as a matter of fact! Check out the dyno video I just posted in the vids section. Matted to the floor on the street in 1st and 2nd.
Whipple guys, help is hopefully on the way. You can run an R6 if you're a sunny day only guy and get good traction, but there's a good chance Goodyear will produce the GT size tire in the GT500KR r-compound for us soon. Not a huge difference, but it will definitely be better than stock. Bony runs the non-stock sized PS2's and has nothing but good things to say about them.
Just watched it again Dave. Do you run a separate boost gauge? The stock gauge was hitting approx 15 from what I could tell.

It's not going to go any higher then that regardless of the actual pressure.
Dave you need a DashDaq I have mine set up with a 3 bar map so you can watch pressure in the car up to 30 psi if you want.
Not yet. I'll probably buy the freeflyer one eventually. We plugged in a real boost gauge, not a dummy, today and it was around 23 I think. When we monitored it in Florida it was doing around 837 @ 18.
Does anyone have any experience with these?

AEM makes pretty good stuff as a general rule, though mostly imports use it. I had been scoping that as well because I think a digital gauge is a nice touch, even if it doesn't match. I'd just run it somewhere inconspicuous.

I find looking at the boost gauge which driving of little value. When the boost values become of interest, I am looking at where I am going not at gauges. I think Torrie is on the right track, use a datalogger so that you can log boost as well as other parameters to view when you are more relaxed. Most everyone that upped the boost on a GT will have a SCT or Diablo turner that can be used for datalogging. I don't know about Diablo, but the SCT has 2 analog channels of 0-5 volts that can be used to log data along with more than 100 other numbers. I have one of the channels setup to read wide band O2 from a Innovate LC-1. That works great.
Torrie has got me thinking that I have to add a Boost sensor as well. Torrie do you have a part number for a Boost sensor and datasheet for it?

Agreed. When your runing around at 25 or so PSI like I do sometimes its real nice to be able to have a needle reference point within eye shot. At least for me. But yes being able to log it with a device is great too the Dash daq can do that, the SCT X3, Xcal 2, and livewire all can do that too.
Ill PM you the info

I went with the Hoosiers R6 tires when I did the upgrade. The car has better traction now with 700HP then it did with stock HP and the factory Goodyears. I got mine here with the "dry intermediate" grooves: http://www.rogerkraustires.com/RKR/groove.shtml
I have no affiliation with this company. They shipped them fairly quickly and the price seemed fair. I am very happy with the results.
Appreciate the link. I was told that Hoosiers will pickup quite a bit of road debris that eventually will start eroding your paint. Can you comment?
Thanks

Any soft compund tire will pick up debris. I have gone thru a handful of sets of R6's out back and its not that bad.

my car makes 730 ft tq almost all of it at about 3400 rpm and i have the stock tires, in second gear at about 2600 rpm i can floor it and i have no problems with traction, almost to the point that makes it feel boring to drive(It would feel faster if the car was all over the place, which usually is the case with most other cars that make anywhere over 500 ft tq). so its a testament to the chassis of the gt to be able to transfer all that torque to the ground with no problem. anyone can loose tranction in first gear with almost anycar that makes any sort of power sans a traction control, so i think the gt has tremendous grip, so much in fact that Im going to up the power, and let see how much it can handle.
on another note I saw the dyno sheet of dave's car and it seems the turbos come on very strong at about four thousand rpm, so almost like an on off swich this is the reason why traction becomes an issue; one second there is nothing and the next wam you get hit with a rush of power, I think this is where the supercharger has an advantage the area under the curve of a supercharger is more consistant and it make power and continues to make power accross the rpm band,(without any spikes) this is easier to control and more fun to drive to me at least , however the lack of power on the top end is the disadvangate of the sc, but like shadowman said combining the two should make for an ideal set up. very broad power across the rpm curve and more on the top end, that must be a dream to drive. Im currently considering this setup myself, but havent decided which turbo kit im going with. this is real interesting stuff and i cant wait to see how the results turn out, thats why im eagrly waiting for torrie to post some numbers,.. torrrie where are you?
