Max RPM for shifting?

[spoulson]

I bought this car not long ago and is now running smooth after fixing up some problems. One day this spring I plan on taking the car out to the track to see what it'll run. So, I was wondering what max RPM you think I can take the engine to before shifting. I know this is a little armchair racing, but I'm just looking out for some definite do's and don't's.

My major mods are in my sig. As far as the valvetrain, all I know is the pushrods are hardened and springs are duals. I don't know the brands or specs of the springs. RRs are FRPP 1.6's. The AFM N-4 cam is pretty lopey and wants to pull hard past 6k rpm if I let it. The oiling is upgraded with a Melling high volume w/ hardened shaft. Rear axles have been upgraded and are 5-lug, but I don't recall the spline count.

Would you guess 6500 is safe? 7000?

im pretty sure the REV limit is around 6200. you pretty much stop making power around 5500. just depends on ur setup

6200-6500 is where that combo will want to be shifted. Better have good valve springs.

factory fuel shutoff is ~6,250 rpm, to get past that you need a chip or find an old rpm extender to use.

I guess I overestimated the RPMs this engine can handle. I've taken it to about 6k and it handled just fine. Sounded mean!

At the risk of stating the obvious, I would suggest first establishing a generally safe max rpm in your mind first, and then test the car out. You may end up hitting a level where anything past it is really not pushing the car optimally anymore and you would do better to get the next gear in.

As was stated, this all depends on many factors, including your tranny and rear end gears.

Experiment with the car without blowing it up. Focussing on higher rpms may not actually get the car going any better at all. Focus on the pull instead.

Get to really know the car in this way and have fun with it. Best of luck!
