no need for a driver!

From the logs I've looked at on my car, if I shift at 7000 the RPMs will fall to 5500 before the clutch re-engages. If EVOlutionary shifts like I do (poor guy!), then it seems like shifting at 7200 would be better for the posted HP curve as the RPMs would "bracket" the bump in HP. Is there more to the story?

Ok,,, thanks for the data-- that sheds some light on the topic..

Glad to see how light your car is-- That's awesome, but if you can find another 100lbs to take out the car would be so much happier.

Your driving technique is spot on!!! And 100mph to the 1/8th on a green is just right.

Your problem is that from the 1/8th to the 1320, you are only picking up 22mph. This is a red flag!!! Something in your combo is loosing power and/or your power is not getting to the ground correctly in 4th (slipping clutch, pulling timing etc).

You aren't going to find much more in the driver seat,,, the key to running 10's at 125-129 is either under the hood or in the ecu.


Hope this helps!!

The graphs posted from dynosheets are usually 3rd or 4th gear pulls. On NA cars the graphs are more consistent gear to gear, but turbo cars are affected more based on load per gear.

The op should try different shift points to find the 'sweet spot', but the 1-2 shift can benefit from the added torque 'hit' that the green will give him with a 7k shift.

Ultimately we are talking about a 200rpm variance, so the speed that he shifts is more important than the rpm he begins the process. He seems like a pretty decent driver from the slip breakdown, but 22mph on the second half is more of an impact than the driver's ability. Stock turbo cars pick up more than 22mph on the back half. I love that 1/8th mph though!!
