Im thinking about changing impellors to one thatll absorb more hp and was curious if im in the ballpark on my own guess.

runnin a lm7 with common mods,bolts,rings,studs,ls7lifters
cam is a 545 219/228 114 installed straight up
twin on3 70mm .81ar turbos blowing into a lake water cooled(70-80* constanly) a2w ic with 2 5gph pure meth nozzles on ic outlet tank blowing into a csu hat down a qft 750. im thinking 950-1000 hp at the crank at 18-20lbs around 6500-6600 what do you guys think.martin said he liked the cam.turbs have a short dump on each.

same engine last couple seasons had a single s480 83mm logstyle hotside system i fabbed up and by impellor chart it made 850-900hp at 6800. Same cam carb etc i just converted it to twins and intercooled along with meth plus changed hotside to up and forwards with twin 60mm gates.wanted to free up hotside alot and lower iats alot more.pumpgas 93. Am i way off on expectations at the crank?

Shoot me yalls email ill send yall sum i was hope'n for quicker spool from the twins as well as lower iat's now that ive added the a2w as well.my log system ran great but its wasnt the high rpm breather i needed so i made the switch.

log system (pic n avitar) with 60mm gate and small turbine s480 1.1ar with meth injection ----> now up and forwards with twin 60mm gates,twin 70mm .81ar on3's,with meth injection and a2w(lake cooled). hope'n for a grand, im sure ill bend rods at some point but ill build a forged bottom end 5.7 iron ls1 before too long.

Our impellor charts are pretty accurate, usually within 50hp or so as long as pump is loading right.was hoping for another 100hp n 200ftlbs from the change up.am i batshit or within reason? 93 pumpgas on both setups, ran single deal at 20psi and new deal as well.my boost gauge maxes out at 20 or id run more hehe matches my boat so dont wanna change it lol

Omg that thing hauls the mail lmao. I would sell my car to build that. My buddy's does 65 to 70 mph I would say in a 5.3 just cam and intake. That is a whole different animal you have. And that is jet powered! I would say the twins should spool quicker thus being quicker to get to mph.
