I took my M7 non Z51 and no npp option, to MIR today

Bone stock on stock tires:

11.95@119.62


Stock on 315/35/18 mt et street II:

11.72@119.52




This is a very hard car to drive fast at a drag strip, it definately needs TQ management tuned out!

Good job Kyle!
For those that don't know, Kyle holds the ZR1 stock/stock tire record. He is one of the fast guys you want driving the M7.

How bad is it compared to a C6Z or a ZR1?

Kyle Lemish

It is much more intrusive, i made about 40 passes today, trying all kinds of launchs. Its very hard to drive around it. You really cant, you just try to keep it minimal. In my ZR1 i can slip the clutch and get around it pretty good. I want to take a shot at a Z51 car with npp, but my car has neither.

Good way to spend the day

If you don't mind telling me how does the clutch feel since its stock... Mine when my car was stock I couldn't get consistent passes after 5 runs till it cooled down...on stock clutch and tires...In your opinion will the stock clutch last for racing applications and road race.....

RamAir972003

on my Z I would slip the clutch also but couldnt do it for long period of times but again the zr1 clutch was better than ls7s....

Kyle, how many miles on the car?

Mr.Chevy

ِI'm sure you will get the car soon in the 11.6X at least with stock tires. because A6 is already in the 11.4x in stock tires. I don't see anything may prevent the M7 to be better than A6 in the 1/4 mile.

This is not good news for the upcoming hi-po model...

I HOPE they put an AUTO in all future variants of the C7. GT500's are the same way w/torque management issues. Its a pain in the ***.

Snorman ran faster w/auto and stock tires.

I would go auto all the way.

I was concerned about this from the beginning

As much torque as the current Z06 + Heavier + 30% smaller tires = Torque Management

Snorman

And you watched me fighting that all through the late-summer and fall last year at OSW with my GT500. Once I figured it out, the car ran pretty well. I'm wondering if some variant of PTM in a Z51 car would mitigate the TM to a degree (as it does when using LC in mode 6 in the GT500's).

Absolutely!

Not to try and change this to a GT500/C7 thread, but watch what happens just after I launched the car on this pass...

You can clearly see the car nose over about 30'-40' out. The "electronic powertrain feature" that Ford put into those cars just kills throttle angle and power. Once it detects no clutch slip, it ramps throttle angle back in again. I'm guessing this is exactly what GM did with the C7's. I would guess with a tune to remove this feature they'll run VERY strong numbers.
It can be very frustrating.

Maybe we need a fast list for tune only cars as well, so the M7s stand a chance?

RamAir972003

Can you tune that out. Also if I'm correct on the Zs you hit the button 3 times it turns everything I mean everything Car is in your hands no control or nothing.

Snorman

Yes, with the GT500's it can be tuned out by the aftermarket. In fact, I saw a car at a rental a few weeks ago that was having huge bog issues out of the hole...and this was a ~700 rwhp car. The tuner was at the track and removed clutch protection from the factory programming and the car came out of the hole very hard the rest of the day.
I would imagine the same thing can be done with the C7. I would also be surprised if one of the PTM modes in the Z51 cars doesn't turn off, or greatly reduce this.

ZR1 clutch is much better than Z06, but you can still over heat a ZR1 clutch pretty easy. The C7 clutch never had an issue at all, no matter how much i slipped it. But we will have to ask the modded car guys later to see how it really is because 450 hp isnt 638
