Also, Fwiw an LS3 and 5.0 will make in the same area for power with the same blower/psi.

What would be more interesting is seeing how a built N/A 5.0 would stack up to a similarly modded N/A LS3. My $ on the LS3.

Has a meth kit though...and I guess higher octane from reading a bit further down (91 plus some additive).

Boss engine would make more than a Coyote.

Some random facts:

2. People have made 740+rwhp on the stock LS6 short block and it has lasted for years. Some have had theirs blow up at 500rwhp in months. It's all a gamble and based on how they drive it and the tuner (BIG factor).

3. You could say size the blower to the motor, but sizing it for your power goals is a better idea. Its about efficiency. What's the sense in over spinning a little Vortech Si-Trim with a ridiculous 18lbs of boost when you could run a big YSi at much lower boost for the same power?

The debate isn't about if the LS6 can make 800whp with 16-18#, but wether can it do it with a 2.3L blower and stock long block. The answer is No.

A few things to consider though. The 6.2L LSA uses the 1.9L blower at 9lbs, GT500 the larger 2.3 Eaton @ a whopping 15lbs. Huge difference.

My motor is also 11:1 and makes a good bit of power without boost. With the exception of the ls7... i dont think any stock longblock would make that power on 10lbs. Unless its turbo...but i too would make more with a turbo setup.

I was ask you ....

Do you think GM would've used the same blower if they had intended it to run at the boost levels of the 13 GT500?

I never said the same blower......I don't care about that. Read above

Old modular no....new 5.0/5.8 maybe a bit more. After the updated LT1 comes out to match or exceed the updated modulars and your back to sucking hind tit.

This......now your gettin warm

DING ...DING....DING...DING looks like we may have a winner.

No one cares about your boss in every thread. Maybe we'll get a chance to get together so I can smoke that thing for ya.


Winner!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The problem is it would need a larger blower to stay in it's efficiency zone then because it would be well over 700hp. I'll go back to this question.....Do you think GM would've used the same blower if they had intended it to run at the boost levels of the 13 GT500?

With said it would probably need a bigger blower.....probably a 2.6 because it will be moving more air.

Just as the 4.6 vs ls6 originally got all blowed up on here. So now it's either Heater's blower is to big and not operating in it's efficiency zone or the ls6 will make the same or more power on less boost....But at the same boost levels it would and should require a larger blower.

To all who bashed be in this thread.......I'll take your apologies now.

I think the LS3 dominates in that category.



Or rather, FTL!



I dont know about that. Whatever motor GM has planned for the upcoming Z06 and ZR1 should be more than enough to match what Ford puts out.
