This may be a dumb question but I am going to ask :cool1: Can switching trannys actually hurt your time? I went from a T5 to a TKO 600 and I am running about .3 higher than what I did with the T5 AFTER redoing the entire suspension. I also did 4 wheel disc cobra brakes. Not sure if I Just lost the driving touch or if it is a possibility?

It can slightly for your switch...t5 is slighly more efficent than a tko..but not .3 worth. Are your 60' times the same or better with the new suspension stuff?

I'm thinking driver error, and the clutch not being properly adjusted.

Also going from drums to discs will slow a car down

Why's that? A disc rotor doesn't weigh any more than a loaded drum.

Gear ratio makes a big difference. The T-5 have very little mass to the gears. It is probably a combination of a couple things including weather and track conditions.

Very true, didn't think of that. So T-5's gears are lighter than a tko-600's? Makes sense.

Thats why my t-5's were 4spds who needs overdrive!

t-5's are lighter and generally shift faster than a TKO. Could be weather or track related more than anything. Take a hard look at your slips and compare increments and notes you took at the track....you did take notes didnt you?

Sorry didn't see this reply...yeah it has nothing to do with the weight. On the drums the spring pulls the pad back completely away from the drums while there is constant friction on the rotor with discs.

Kinda but most drum systems have a residual pressure valve to keep a little pressure on the shoe so it stays close to the drum. If it didnt you would have a crap pedal.

I agree, but the shoe does not touch the drum. The residual pressure valve just keeps it close. The shoe does not run on the drum the entire time, while the pad is in contact with the rotor due to the pressure from the caliper.
