Maybe 3lbs? But what's the point of that.

Probably I'll just do headers (maybe gucci rockers and lifters) and a retune. This would take me to 430WHP on an N/A 346ci and pump gas still passing smog. That's probably about as good as it's going to get. and in a car that is 3,100lbs full wet, plenty of of power for the street. My clutch and trans would still handle it, and as long as I don't get too sticky of street tires, the diff would still handle that. If I went with a boost engine, I'm not going to dick around, but decompress and go for an intercooled one atmosphere tuned for pump gas. that's going to be more like 550whp and then clutch would be "underpowered" and trans and diff would be ticking time bombs.

First you would make way more then 550 with one bar. And why do you need so much Octane in a mostly stock LS1? People run 7 psi on stock stuff all day long with only 91. Hell I only run 91 with 10.5:1 and 5.5 psi

It's only if it gets hotter in the summer and I push, it pings a little. The 93~ is just for a safety margin and to maintain timing, it's not strictly necessary. And in many parts of the country 93 out of the pump is still very common, it's not really exotic.

The 550WHP on one bar intercooled on a H&C 346 is conservative/safe, but it wouldn't be a lot more. Who knows for sure unless it was done and dynoed.

I know for a fact with my exact current setup that I made 391 on a Mutang dyno. Getting it to breath on the back side would help a lot.

Guy, lol.

Ben, lol.

Blackax: His LS is about as stock as Sharon Stone is a virgin. Its H&C. And 15 lbs is a lot of boost on a street V8, even for a centri blower.

Also Ben, nitrous is no different than anything else. Its just a chemical supercharger. Cylinder pressure is cylinder pressure. If I ever run the Vette as a drag car, Id seriously consider nitrous for 3rd and 4th gear.

Also, its not like the movies. The car I drove with nitrous had a WOT setup, so you leave the switch on and it injects only at WOT.

I'm not doing nitrous in a street car setup. I'm not maintaining shit with refills, etc., and not going ot have something that can run out independently of fuel. Car+fuel = done.

When nitrous runs out, the condition is overly rich. Safe for the engine. I <3 nitrous

Does a blower run out?

Listen, ain't hat'n on nitrous, just ain't gonna do it. Frankly, more inclined to really refining the NA motor than even FI. That's the gentlemen's game and I'm nothing if not a fucking gentlemen.
