TT GT350???

[G-FORCE]

I realize these are designed to be fun streetcars or track cars. I also get the weight balance issue but I can't resist wondering how they would respond to moderate (>12lbs) boost levels via a couple twins. In fact a little bird told me one of Hellions dealers might be working on using the standard GT kit and believes it is a direct fit. Anyone else curious?

I'm sure as hell curious. Turbo isn't for me due to the hassle but would love to see the numbers it makes.

I'm very interested, but probably wouldn't buy. Too much money and I wouldn't want to be one of the first. I need to get used to the current power levels and get bored with them before spending a bunch of money to up the power. I would also probably do rear gears before a power adder.

It would be interesting to see how the motor would respond to adding some. I would probably be too scared to try it given the already high compression in stock form.

A couple of twins?! What's a car going to do with 4 turbos?!

Just kidding.

I'd like to see what the turbo route would do on the 5.2L. I think it would respond pretty well. We have found out that the motor handles nitrous pretty well and will find out how it acts with a 2.9L Whipple here shortly. Turbo is the next logical test.

"Couple of twins" DUH on my part. But now that we mention it........

Probably would have face ripping throttle response. I know everyone gets all worked up about the high compression ratio but from my understanding, that higher compression ratio keeps the turbos spooled up with the correct application. And just because compression is high doesn't mean the engine can't handle it. There's more to compression tolerance than just a number. I have no interest in forced induction on my car but I also want to keep it real and a turbo would be interesting for sure.

Couple of Twin...Scrolls ;)

The Lethal GT350 makes 819 rwhp with a 2.9 Whipple.

Turbos are going to be sick.

Well...even sicker than the already sick 2.9 Whipple...

A twin turbo setup would be the flu!

Would be interesting to see. I prefer turbo if it's OEM but aftermarket cars always seem to be broken. I'd DD a whipple WAY before I'd DD an add-on turbo kit.

What lethal has done with their whipple set up is off all hooks amazing. A turbo set up set up could be even more so. But, and I don't feel good about saying this, I'm not sure if that much more power would serve the balanced feel of this car.

While there's not a lot of grunt down low in the GT350, those not afraid of down shifting can easily overwhelm the tires whenever the desire hits. The handling and precision of the car don't, in my opinion, require a massive infusion of power.

Then again, I wouldn't mind another fully warrantied 50 or so ponies and # of torque. Doesn't need it, but I wouldn't mind it .

It's that high compression that don't mix well with boost and to make it worst, add the high RPM to it. A bad tank of gas or a detonation can easily send that motor to graveyard.

High compression isn't always a bad thing in boosted motors anymore. Tune it right, back of a degree or so in timing, it's all good. With turbo setups especially, higher compression gets the turbos spinning faster and gives better response. This is practiced very heavily on GTR's.

Its always about the tune believe me! I had a stock 4.6 engine and internals Mustang 2010 with a D1SC procharger upgraded to 8rib system, i was around 8psi, GT500 fuel pump, Diablo Mafia, and it was my daily drive for two years I drove over 100,000km with the procharger and never had a single issue ( keep in mind average temperature in summer time which is about 9months every year is around 50c). Another thing is that with a supercharger there is always a limit of how much you can spin the supercharger before it maxes out and I'm sure it wont be able to handle 8250 rpm it would max out way before that, but with the turbos they'll never max out as the turbo will keep spooling across the whole range and with the high compression that will help with eliminating the turbo lag as it will always make the turbo spool faster and easier. I would really consider a Turbo system on my GT350 but definitely wont be doing it until someone else keep experimenting on their car first lol

Wellllll... Turbo's do max out, so to speak. The peak flow across a inducer is based on the flow map of the turbo, so once you go over that sweet spot of the Turbo you create a lot more heat and the efficiency goes down.

You size the turbo for the peak power and flow you want (i.e. bigger turbo, higher HP but also more Lag because it takes more flow across inducer to get the turbo up to speed.)

Higher compression does have higher exhaust energy but that is also determined by how much air you are moving through the motor, which is determined by your Cam timing, duration and lift. Its fun to design a turbo to meet a motors specs, but you look at a lot of flow maps to get it matched up to deliver peak performance with maximum efficiency.
