how much can a stock ls1 block handle out of a 2000 camaro. about how much horse power and torque can it hadle before i would need to worie about something letting go?

 

Every motor is gonna be different. I have a stock bottom end, stock heads LS1 that makes about 600 at the flywheel on a 150 shot. I spin it to 7500 rpm's, and have been through about 30 10 lb bottles of nitrous. Run's like a champ, but it's on borrowed time.

 

The fuse is lit on that bomb...especially with those stock rod bolts ...

 

most people would agree that 550 rwhp is the limit, and Id say your probably pushing it at that point.

 

I pretty much agree. I make 515 to the wheels through a stalled TH400 and 12-bolt. The metal shavings on the oil plug are getting bigger.

 

thanx. im going to keep doing resreach befor i bolt on anything. anybody know how a stock motor holds up against a vortec charger. the 50 state legal bolt on kit?

 

Keep it under 8 lbs of boost and you'll be fine with a good tune.

 

The bottom end is as strong as its connecting members and how they are or where taken car off before you got it or you did any upgrades. There are some engines pushing 700 hp with a stock rotating assembly but I would not suggest it. About 475 rwhp is the best if you want to have any type of life on the stock internals (ie 150K miles plus) But by that time most have already done one of two things, either a stroke or an engine swap.

 

I have 96k on my stock bottom and make 527rwhp 530rwtq I have run prob 35 bottles through it on 150 shot and just steped up to a 200shot, no issues yet but only reving to 6700. A good tune plays a big part.

 

Keep the RPM's normal and keep boost to no more then 8lbs and you should be fine. This is also assuming you'll be at or under 550rwhp.

 

recently I made 2 dyno pulls on nitrous putting 600/591 to the wheels through my stalled auto with the stock bottom end. (made 452 N/A)

I took it to the track this past weekend and made 3 N/A passes then started spraying, it made 3 passes the fourth sent a rod through the side of the block. I would say the 550rwhp limit people are saying is a good idea. My last SS made probably 20+ passes on N2O at about a 560rwhp before i got rid of it. im guessing I was probably looking at close to 620rwhp had it been in a stick car.
