Z elim, I might be wrong but I'm under the impression that you are also running a higher rear gear ratio, is that correct? If so, aren't you concerned that adding an SC will not be overkill? I wonder in general, if you run 4.08's and later add an SC or TT, even with the GTM TC won't the car be almost undriveable? I foresee major traction problems on anything short of drag radials. I'm not talking about the increase in frequency in shifting that such a combination would cause, just the overall driveability.

This would be my primary concern, even given sufficient traction. Even in bone-stock form, 1st gear on the 7AT goes by very quickly at full throttle. It goes so quickly that it's very hard to get the timing right for the 1-2 upshift without clicking too early or bumping the rev limiter (keep in mind the shift isn't instant anyways, there's a factional second of input and engagement lag).

4.08 gears alone would make that situation even more difficult, and then adding SC...

Maybe some have far better reaction ability than I do, but I think first gear would basically be a waste at that point. You'd just click through to 2nd early to avoid bumping the limiter before you can blink.

there is no real power abouve 7400 rpm,
My tack is also out by 200 rpm at the top end so 8100 = 8300 rpm.

Thanks, I'll aim for 7400 rpm next time :tup:

Z eliminator: Props to you for taking the time to chronicle your trials and try to make sense out of a complicated product. That it does not make immediate gains on the strip doesn't surprise me. That it is consistent in it's delivery makes good sense. It's a good product.

How well I know how difficult it is to get better ET's through any product. There always appears to be outside influences that affect.

I wish you continued success. More power = quicker reflexes. Go for it!

Your car is MOVING! Congrats!

On the track I still have to launch the car, modulate accelerator to keep wheelspin down, shift as fast and smoothly as possible manually all while making sure I'm still going straight.

Don't get sassy. I was just commenting that this is, as he said, becoming a question of how much you can remove driver error and how efficient you can make the car at putting all its power down. Some might argue that's taking the fun or skill out of it too.

A lot of Formula 1 drivers were very happy when they got rid of TC a few years ago even though they knew they would lap slower.

All that being said, I am also very much looking forward to Z Elim giving jnaut some heat. Only way to keep making cars faster.

Im glad this dude is GONE :happydance:
