L99 guys, where y'at?

[2PitbullSS]

Great info ya'll! Keep it coming! Some input from Mast on their cam packages would kick @SS.

Another L99 guy that's interested in watching this thread.

no its really only for shifts.. it feels a little better, but not like a night and day difference. I did not mess with any shift pressures at all. But burn outs, no doesn't make it do one.. lol

I actually haven't tried, but I think it would just spin like 1 time... hahaa

Question,

Does turning off TM let this car break lose with just turning off traction control and stomping on the gas?

Right now the only way to spin them is power breaking and I am not a real fan of that.

Turning off or reducing Torque Management will allow for more power to go to the rear wheels, especially on shifts (like 1-2, 3-4, etc, shifts). Torque managment pulls power on the shifts to reduce wear and tear on the transmission.
I've seen automatic GTO's drop .2 -.3 tenths in a 1/4 mile by having the car tuned and turning off the Torque Managment.

Torque Managment and Traction Control are two different things, but without TM you can get yourself in trouble if your not careful. Why? Because the shifts are so hard and crisp, you can get out of shape really easy if the roads are wet or even in cold dry weather.


And also be careful what you wish for. I had the same issues with my stock A4 GTO. It would not break the tires loose at all when it was new. The stock tuning + new sticky tires+ warm weather = great traction off the line. Which is actually a good thing at the track or on the street.
Spinning = not winning a race.

But after getting a few bolt ons (long tube headers, high flow cats, catback, intake, and a tune -no torque management) I couldn't get any traction at all at the track in cooler weather. All I would do is spin my tires. It was ridiculous. So having traction leaving the line is a good thing and you will wish you still have it, once your car gets a little modded and tuned.

Then you'll be shopping for drag radials to keep from spinning.

as for mods, I dyno'd it stock was only like 323rwhp, I already deleted TM and tuned some timing etc.

I will only have a chance to redyno when I get "everything" on, so should be a couple weeks.

man that seems low, shouldn't it be between 340-350 rwhp?

mustang dyno and 400hp in an automatic minus the 18-20% drivetrain loss.. no its correct..

It does seem a little low, but

Automatic GTOs (also rated at 400hp) usually dyno around 310 - 330 rwhp range.

The M6 (6 speed stick) GTO's usually dyno around 330 - 350 rwhp (on average).


These are just averages. Some guys dyno higher, and some dyno lower. I've seen Automatic 05/06 GTO's dyno as low as 300 rwhp. But the guys 05 GTO that dynoed 300 rwhp ran 13.3 @ 106 mph at the track. So dyno numbers can be deceiving, especially when dealing with automatics.

Picking my car up at Corsa exhaust tonite it is a L99, should be the last time they will need it. Will let you know how it sounds. Maybe even post a clip if I can.

You better! lol

I deciced to beat the AFM thing by going all out and droping in a built-up LS3-427 with all the good SStuff. I start photo documenting tomorrow AM at my engine builders shop.

No you need a stall converter for that ... VIG 2800

Stay tuned I will have numbers and dyno video of the Mast cam next friday ...

which one? stage I or II? You tuning with HPT beta or live?

[mlee]

I should have Corsa Exhaust on my L99 next weekend... plus tune and CAI from Hennessey. Will let you all know how it turns out....
