I was wondering how many rpms your cars are dropping during shifts....
Does anyone have direct scan and could look to see what their rpms drop to???
I am slowly dialing my car in, and looking at my aftermarket tach during a 2-3 shift my car revs to 5000 and shifts, but only drops to about 4300-4400 and goes back up to 5000.
I feel that the motor is spending too much time at high rpm, and i want to lock the convertor next time and see how much more it comes back down to..
It has a 3200-3500 9/11 convertor in it, and this was when it was not locked.....
My daily has the stock cam in it, and feels like the valves are floating because it doesnt really make much power past 4400....well, it does make power, but it feels like it makes alot more power from 3300-4400 then it does from 4400-5000....
valve springs are 3-4 years old, 7,500 miles, 6,500 in the past 1 year......but i think i need to replace them again.
When i was racing a 440 charger this summer, at the top of every gear, my car would feel like it was nosing over, shift, then take right off again...
Again, convertor unlocked....
I wished my convertor lockup switch was easier to get to, and i wished i wasnt raining all the time, gonna snow tomorrow now....
So, i think it has 2 issues, worn valve springs, and not taking advantage of my lockup convertor on the street to lower the rpm range...
So, a 3200-3500 stall, what should it drop down to between gears unlocked...
