how high can i spin it to ?
ima be running alot of nitrous about 300ish and just wondering how hig can i spin it ..

 

I'd spin that to 6800k all day and never look back at least thats what I do with mine.......

 

6500 easy
7+ if you have big huge man *****

 

My rev limiter is at 7200. Shift light at 6800. Stock crank, rods and pistons with Katech rod bolts.

 

How cares how far you can spin it, strap it down to a chassis dyno and see where peak power is, then make a determination from there on how far past peak you want to shift it at. 300 past is ideal.

 

True it could fall off on the power whats the point of hanging it out if you don't need to

 

You spin it only as high as it needs.
Meaning you shift at a point where you keep the maximum average Hp between shifts, no more no less, all other methods are futile.

 

I thought he was asking what is a safe rpm limit to not exceed or go boom.

 

yes to both ..

looking at how much rpm i can play with .. but i will be shifting at the best rpm to end up in the powerband for the next gear ... 7+ k too much ?

 

Whats the cam look like?

 

What size cam do you have?

 

ms4
fast 90/90
PRC stage 2.5...

and well everything else too .. i knw the camm willpull up high .,.. just looking for hom much rpm its capable of .. im coming from a high hp rpm rotary .. so going form 9.5k to 6.5k is a lil wierd ... lol
