305 TPI 5speed manual! time too shift between gears

I think that there is something wrong with my camaro :/!I dont think it should be like that, but you never know.. I need opinions from people..

How fast do you have too go to shift two second,third,fourth, and fifth gear, like saying your racing with friends just for fun.. I always have too shift from first-second like around 15/20mph..second-third 30mph... Third-fourth at 40...fourth-fifth around 50/60.. cuz if I dont shift at that certain speed, the rpms will go all the way to the red numbers like at 60rmps... I don't think its supposed to be like that..

The car is all stock!!

Who knows , too many variables.
How many miles on your engine , how good is the tune?
Maybe he is a better driver?
Maybe he has a NOS button under the dash ................

Re: 305 TPI 5speed manual! time too shift between gears

You also have to consider the rear end ratio.... same rpm, different rear end will mean different speeds....

I have the same engine/tranny combo and I would say your shift points are about where I shift....I also find the car is a little slow than my 85z with a T5 since that car had a 3.23 rear end and it rev'd up faster.....

I don't trust factory instruments too well any more. Jim is right just feel it out, I suggest doing it alone for a while first. I can get up to around 40 in first gear before needing to shift with my t5

Re: 305 TPI 5speed manual! time too shift between gears

Thanks for everyone, thats what I'm going to try to do, feel the car, but in case I don't notice any difference, what should it be the the speed to switch between 1-2? Around 30-40mph?

You guys are going about it all wrong. Its a TPI Stock car. Your max HP is at 48-4900rpms. Thats where you shift at. 5000 is the max. Don't go by speed. Think people think!

So why are you posting now? He had a concern and posted in the appropriate section to get the answer he needed. That's why this forum is here.
