Zl1 supercharger
Look up LSA supercharger there are some that sell cheaper than that, They used to sell for 5-6 hundred but that was when GM was in the middle of replacing them and the market was flooded with them. I paid $1100 for a brand new one and $379 a new lid. The price has almost doubled on both in the last year.

Just picked one up in person this past weekend from a main supplier of LSA superchargers and that's what he told me at least.

Brand New LSA from the dealer....at least my dealer.....is only $2,100. That along with another $1,000-$1500 worth of stuff....not bad for about 700 RWHP.

my ls7 cracked and piston so I’m doing a forged ERL 6 bolt 1/2 inch stud 427 block with lsa heads for now (cheap) and a lsa zl1 lid blower trying to hit 800whp on e85 blower only.
i was told my ls7 accessory would work same as a ls3 vette but would need some machining on the pulley to make it fit. You guys think 800whp is achievable
I wouldn't go with the LSA supercharger or heads with that engine, You'd be much better off with the LS9 supercharger and aftermarket or ported LSA/LS9 heads.

I don't think you'll hit your goal of 800whp with a stock LSA supercharger and stock LSA heads. Stock LSA supercharger and good heads would put you in the 650-700rwhp range from what I've read, Add another 40-50hp if you have the blower/snout ported.

was as told by my tuner a 427lsa could hit 800whp pretty easy I’m kinda doing the steps in intervals porting and all will come later

I would be really surprised if you hit 800rw with an lsa blower. There is only so much power you can get out of a 1.9L . If I were you I would do some research and go with a blower that is capable of reaching your goals.
800 to the tire with those heads and smallish blower is going to be tough. Your heads will hold you back quite a bit. I would study some other builds and see what they made and what it took to get there.

725 crank hp
is about 640ish wheel not bad for a stock non cam lsa with that stuff a 427 a blower cam ported lsa heads ported blower and snout cold air intake and e85 should easily see 700whp I’ll be happy with that how bad is the heat soak problem?
