Going to the track, got a stupid question

[MEDIK418]

No one mentioned changing your shift point. I dont powershift because i am too broke to fix any broken parts on my daily driver...but shouldnt you start the powershift a lot earlier than a granny shift??

Not really. Most shift points are aimed at shifting before power starts to drop while still not shortchanging yourself. It's often difficult to determine that point without a dyno but usually you can tell when your particular engine quits building power. Pick your shift point accordingly. Done correctly the whole shift takes a split second and the engine shouldn't be allowed to rev too high. This is the key to any powershift. Speed and accuracy. If you find it takes you too long to complete, either practice more without the throttle on the floor or find another way to shift.
All this should be taken with the knowledge that T-5's tend to grenade if powershifted wrong or with a lot of horsepower tugging on them. One point I want to reinforce. . .5.0's have rev limiters built in and I doubt you can rev it too high before that kicks in. It ain't a fun thing to do but it should survive it a few times anyway.
Still. . .your engine, your decision.
