What is the better transmission for tuning zl1 auto zl1 manual ?
Thank in advances,

Both...

manual has more rwhp due to less drive train loss.

Auto will be more consistent and lighting quick with a transmission shift tune.

If your looking for just raw dyno #'s then manual.

If your looking for quicker 1/4 #'s then auto.

Do you (or anyone) have any actual side by side dyno numbers that show what the difference in RWHP is between the two transmissions on bone stock cars?

I'm just curious how substantial the difference really is.

This has come up on this board before and it has been done before but unless you have a lot of modifications to your car already, you would be much better off selling the car with the auto and buying a car with the manual. The ZL1 auto and manual transmissions are unique to the Camaro ZL1 and the Cadillac CTS-V. They are more robust than anything in any other GM car. The auto and manual transmissions are different lengths so the you have to change driveshafts and the rearend is different in the auto and manual car.

If you have an auto and want a manual, sell your car and buy one with the manual.... you will come out ahead that way.

We have an LSA dyno thread on this board, if you look you can find all of the answers for yourself.

Since I know many of the cars on here and some of the owners do not say up front if the car is auto or manual I will help out.

Post 5, is a stock manual. Post 6, the stock manual graph is the blue one. Post 12 is a stock manual graph with an intake only.

Post 9 is a stock auto with an intake , post 20 is a stock auto trans with and without an intake, bold is stock intake.

On page 2 there are 2 nickey stage 2 cars, similar upgrades from the same tuner on the same dyno...post 30 is the manual and post 34 is the auto.

Kboom is correct the manual transmission puts more horsepower to the ground if the type of racing you are doing is not as dependent on the speed of the shift.

stock manual cars are 495-500rwhp and stock auto cars are 470-475 rwhp

Thanks for the link but I did look through there. What would be nice to see (to ensure it is the most accurate info) would be using a 100% stock auto and a 100% stock manual on the SAME dyno the SAME day. I did not see a comparison like that unless I mistead something?

No doubt there is a difference with the manual having more HP to the ground but there are too many variables comparing two different pulls on different cars on different days.

No worries, it's all good. I am just curious (I have a manual).

Buy what you would prefer to drive, there both fast and a bunch of fun.

Absolutely! I own a manual but drove both and BOTH are incredible cars.

But you should drive both and then decide. Don't 'settle' regardless!

These are really close...this is honestly what one could expect from these cars...Mine made 476 stock and 496 with a CAI and a Tune.

I would say stock there is a easy 30rwhp difference. The numbers will range from 440-500rwhp stock depending on the dyno, the weather, elevation, etc. I have an auto an trap the same mph as the manuals with 30hp more.

Figure 15% drivetrain loss on a manual and 20% loss on a automatic. You can do the math yourself.

[EvilZL1]

Sometimes some of us are not in a position to trade and have to take the long and hard way to have a manual

[geforce]

When it comes to tuning your ZL1 is there any benefit that you would get from a tune on a Auto transmission vs manual, I think there was on the

LS3

L99


Thanks again !!

Really nice of you to take the time to post that info.
