2011 GT Finally in 11s

Finally got my 2011 5.0 to see an 11.98 @ 119.49 after some work and a new set of tires. Back in January, tried to use the nitrous, but it failed to engage. Swapped out the 26" ET Street Radials for 28" Radial Pros and thought I had the nitrous fixed, so went back. Still don't have the bottle heater installed, but I thought I would still get some decent numbers. Didn't have my camera charged (decided to go to the track mid day), so no video. I'll just have to go back.

With the new tires at 20psi, the NA times dropped from 12.2 to 12.6 and the 60' is bogging badly down from 1.8 to 2.1-2.2 launching near 1500 rpms (automatic). They have incredible grip, too much for a mild car.

Quickly discovered the RPM window switch is getting a bad tach signal. The coil doesn't seem to be a good place to get a signal. Bypassed the RPM switch at the track and ran the nitrous manually.

Firing nitrous in 2nd gear brought the ET down to a 12.2 at 118 mph. Last pass of the night, I fired in 1st almost off the line and pulled a 11.98 @ 119.49 mph with a 1.96 60'. Horrible 60' for a car that has 0 tire spin. Oh well, yet another excuse to get more practice. :laughlitt

I'm hoping Bama has a version of the race-hybrid tune for nitrous I can use. The race tune optimizes top end and street optimizes low end. Their "hybrid" optimizes the entire RPM range. Between getting a bit more low end and installing the bottle heater, I hope to get more in the mid-11s before summer hits. Will I be able to stop at mid 11s? Probably not. I already see front runners in my future once the 100+ degree summer passes.

I'd find a dyno shop and have two tunes for the car...one for street and one for NOS...Houston has some good shops, ask around
Also you might want to try a progressive NOS controller, that way you can get off the line better

Thanks, I had talked to them on Monday, no hybrid tune for nitrous. Just last night finished wiring up the bottle heater and an Autometer tach adapter which fixed my RPM window switch. Yesterday I remembered I had put my lower control arms somewhat low on the relocation brackets. I'm thinking if I raise the LCA to a more level state, it'll reduce drag and I can get the 60' back down. Only one way to find out.

Okay, I'm glad to hear you've already been in touch with the Bama team. I'm sorry we can't offer you a Hybrid tune, since you're running nitrous. I'll touch base with them, to see if we will be offering that option in the future or anything along those lines!

I bet if you raise the LCA's up a little bit, that will definitely help with Drag. You should be able to drop your 60' down!

Let us know how that works out for you! Please let me know if you have any questions or need some assistance in the future.
