Could my converter be slipping like mad?????????
Re: Could my converter be slipping like mad?????????
Wait a minute...
The converter is supposed to slip. For example if there were no slip, then on the 1-2 upshift your car would drop back to around 3500 rpms. That is clearly out of the powerband and your car would fall on its face. My converter holds 5500 on the upshifts. I'm getting some torque multiplication and feeding much higher HP into the converter than if I had a low stall converter. The last thing I want is to get rid of the slip below 5500. On my converter, eliminating slip above 5500 would put more power to the rear wheels, by about 13 HP.
If your converter is holding above your peak HP, you have too much slip. Likewise a more efficent design might save you some HP on the top end. Don't trade the converter in if it is doing its job.

The example I was talking about where it happened to me the converter would only slip on gas. It was a 4k stall in a th350. On motor the rpms dropped to about 5k on shifts. As soon as I sprayed it the launch felt soft and the car stayed around 6600 all the way down the track. Even when I shifted.

Re: Could my converter be slipping like mad????????? I don't know anyone with the same set-up as me. I'll have to have a friend drive it who has allot of experience with auto's, fast ones to.
I guess I have no use for a 3600 stall for a street car. If a 3200 will give me better mid and top end pulling, thats what I should get it restalled to.
But what about the str thing, I have no clue what that is or what to have it set for?

Re: Could my converter be slipping like mad????????? Quickin,
Give PI a call and tell them the info I told you they would need. PI can restall your converter or TCI would restall your converter. Stop beating yourself up
and let PI or TCI do the work for you.

Re: Could my converter be slipping like mad????????? You're a mess Lyle. 
I bet your PI3600 is stalling to like 4500 behind your 436ci motor.
I bet the rpms go to like 3000 before the car starts moving from a light. I'm guessing you see a lot of rpms if you wack it from a roll.
You really cannot have it all.
I'd go PI3200 if you never race at the track and you think that your current converter is too loose from a roll.
