That seems like a pretty large range between the two stats?
Thanks...Swifty

Been awhile since I looked at the KB site,I see what you are talking about...those numbers are of course FlyWheel #'s. But also just because a kit is capable of making numbers on a "completely stock engine" doesn't mean the engine and driveline will last. The range is because you can change pullies and change the boost...ie run a big pulley make lower boost therefore less power....or run a smaller pulley,make more boost and more power.
Read all the way through on the site...nothing against KB but their site can get a little confusing for some when they start reading the ramble.
At 16psi they bent all 8 rods...even at 14psi they were running C16...again regardless of the big print I still say you won't make even 1000 FWHP(~850RWHP) reliably by just bolting on a KB kit...you can probalby make it ...but I doubt it will last. Also when they say stock with a KB kit even they are including add ons...their 115mm TB,2 BAPS ect...those are add ons to their kits..but that still doesn't help the piston,rods or the driveline live. If you want to make that kind of power reliably you need a purpose built short block with lower comp and at a min forged pistons and forged or billet rods..and that still doesn't adress the rest of the driveline. For instance I doubt the stock clutch will live long behind that power...if you are actually using it...then there is the rear axles..and everything in between...it goes on and on...and gets very expensive very quick to make big useable power..now if all you want it a big dyno number doing it "all stock" might be fine.

HP POTENTIAL Twin Screw superchargers MUST RELY ON LARGE FREE FLOWING INLET SYSTEM TO PRODUCE MAXIMUM PERFORMANCE. The 2.8, 3.6LC and 4.2LC Kits all use a huge air guzzling 4.5” filter, 4.5” MAF meter and 4.5”x4’ long Ram Air Pipe feeding the MAMMOTH™ inlet manifold (accepts up to 115mm throttle body). Compare that to the competition. Kenne Bell “0” restriction - short runner discharge manifold, intercooler and heat exchanger are designed to support 1000+HP on a 100% stock motor. Forged pistons and rods are necessary at some point but the kit components including the 2.8L will support it, so there’s no upgrading of basic components necessary with the 2.8, 3.6 or 4.2 kits. Just upgrade the stock 90mm throttle body to our 115mm. See Tech Tips for dyno tests. It fits the oversized Kenne Bell MAMMOTH™ inlet manifold and 4.5” inlet system
