high rpm's

Bush18 · October 10th, 2009, 02:33 PM

whats the max rpm's the factory rotating assembly should be safe at. looking into building a high revving n/a setup. heads, cams, intake, lt's, valvetrain. lighten up the drivetrain a bit too.

Bush18 · October 10th, 2009, 02:36 PM

its a 00' gt

limited · October 10th, 2009, 03:04 PM

I would not go over 6300,that could be pushing the limit too imo

Boostang · October 10th, 2009, 07:07 PM

well itd be hard to get a intake to flow past 6k.. but ive heard the stock rotatig assembly can take whatever rpm u spin it

Willy Mo · October 10th, 2009, 08:09 PM

i have seen cars hp curve still climbing at 6000 rpm.. so i would think you could dpin it past that...

DickH · October 11th, 2009, 12:23 AM

What are you doing to it to make it clear a higher rpm? You might be best off redoing internals as well, or keeping it at 6k

Boostang · October 11th, 2009, 12:42 AM

this is what youll need.. lighter rotating assembly (optional) head work/porting/polishing and cams with ALOT of lift

my tuner spun mine all the way to 6500 on the dyno @ 10 psi. didn't hurt it but it stopped making power at 5700.. it stayed even till about 6100 and dropped about 10 hp between 61-6500. i wouldn't rev it like that routinely, but on an NA setup i'd say you should be able to rev it to 6500.

Boostang · October 11th, 2009, 01:33 AM

6500 will be fine.. but if u wannamake steady hp/tq then you need head work!

limited · October 11th, 2009, 12:47 PM

you are pushing the limits of the rods at 6500(mainly the bolts). if you plan on reving that high get a built balanced shortblock and good valve springs in head

You might look into swapping in a 4v bottom end (non-Termie). They're designed to spin 6800+ out of the box, and the weight savings certainly won't hurt.
