ls vtec motor redline

[REDEVO777]

what should a ls bottom end with a gsr head redline at?

[Tech5]

use arp rod bolts I wouldnt go past 7800 thats me...I hear an seen some people rev to 8000k with arp rod bolts........Remember the ls rods/bolts are weak they are design to rev too 7200 rpms not 8200 ...use your best judgement an get some rod bolts!

No higher than LS Stock redline.

What if your built ?... IE rods pistons arps....ect

[scttydb411]

stock 7.2k
rods w/ arp bolts 8k
rods w/ arp bolts, headwork, valvetrain we've reved to 9.9k.

only rev it as far as it makes power and can handle...otherwise it's a waste.

Eagles are good for 9500-10,000 rpms

I have three concerns 1) I had plans to run modest boost 2) I have already tapped to the oil pressure sensor for the oil feed to the head now can I tap from the same place for the turbo feed or is it better to get a sandwich plate 3) I have several cars I can put it in and they all have running motors I have two hatchs eg one is pretty much gutted and the third option is my 2000 Si w/51k

1) with a stock bottom end you need to keep a conservative redlike (7200rpm) even with boost.

2)vtec and turbos use very little oil volume so youd be fine using that same source for both.

3) power to weight ratio is your friend

thanks every one for the input

8k all day...lol

listen to scotty. dyno and just dont rev past what you stop making power at.

[highspeed]

even at the ls stock 7.2k rev limiter pple have problem so be conservative and smart

[shinobi]

thats true wat scttydb411 is saying if go past all the power points there is no point and u will blow ur head if u keep on doing it 2 and then ur going 2 b back at square one
