Off the Line - GTM's TT Vs SC Kits

GUTCH · 08-10-2010, 03:34 PM

OK I know you petrol-heads are going to hate this question but I'm going to ask it anyway seeing as this is what I care about the most. So I need to know.

What's going to get me off the line to 100kpm (62mph) faster, GTM's TT kit or their SC kit?

I know I need to compare their torque and RPM's etc, but I'm a relative noob. So hopefully you guys can help me out.

Cheers.

Let me call JB-370z and we will tell you.

GUTCH · 08-10-2010, 03:43 PM

Why? Does he have two 370Z's, one with a TT and one with an SC?

theDreamer · 08-10-2010, 03:44 PM

No, he has a GTM TT 370z and I have a GTM SC 370z.

GUTCH · 08-10-2010, 03:49 PM

In all seriousness when comparing their dynos, it appears as though the TT kit has more torque lower down in the RPMs than the SC.

Yet I constantly read here that SC's are meant to have more torque down low.

Unless I've misread the graphs.

Well going off dreamers dyno it says he has like 33% more tq hp than other GTM stage one kits. He needs to go get another dyno done but on a diff dyno this time.

Guaranteeing it would be neck-and-neck unless the turbo car had some 355's in the back or at least some drag radials.

You can add all the power in the world, your 0-60 time usually doesn't change more than 0.5-1.0 sec without major traction mods.

That is one thing, I am running 305s in the rear and JB is still on stock tires currently.
I think with equal PSI (8 or less) the kits are fairly equal overall, more of a drivers race, but with a TT build you can throw in a boost controller and dial up to 10 for a bit and have some room for error. SC setup you are set at the PSI and cannot go up or down with changes.

simple change in the pulleys would allow for more no? referencing the sc.

It is one of the things, also need to tune the car, make sure the unit is within its efficiency range with the newer pulley, etc.

true, thanks for the quick reply!

TT 10 PSI slamming the engine at once and gradual boost from 1psi to 8psi with a S/C is a huge difference maker in long term reliability of a motor, a stock motor for comparison's sake. The internals of the TT engine will take more of a beating possibly lowering the life of that motor. Again, all based on a stock motor. S/C gradually get to their top end boost.

lol you BASTARD hahaha ok my 450zTT > TT > SC *hehehehe*

GUTCH · 08-11-2010, 10:01 AM

OK so we basically need a stage 2 GTM SC kit installed to see how that goes up against the TT kit.

Any volunteers?
