300c 6.1(Stock block) + Magnuson Supercharger + HP Tuners = 600WHP Am I at the limit?

Thats about where my car was before a 2.85 pulley on the magnuson, but i did put a hellcat block in to take the increase in boost.

but i never had such good air. always around 2000 DA.

Yeah the DA and prep were amazing last few times we went. Were you using a stock lower pulley? I'm currently running a 2.90 upper with the stock 6.125 lower. Good for 7-8 psi depending on the weather. Do you have headers? stock 3.06 gearing?

shorties, different lower pulley, upper was 3.2. now 2.85 with about 10 lbs, never did i use my race tune and race gas running on 93 street tune, best in a da of 2200 10.85 with a 1.47 60'. Current builder says that with the race tune and a few other tweeks it could be a 10.5. But i did retire from drag racing last year due to health and age issues.
Oh head and cam package from Arrington, true cold air intake, built trans and drive shaft, 3.06 srt pumpkin, exhaust .

That's an awesome 60'...I couldn't shoot out of the hole any harder than 1.62. Most runs were 1.66-1.70 60'.

Hellcat block gives you more CI with the bigger 4.090" bore which is great. I plan to increase the bore, and do heads/cam when I eventually will have to build the engine.

with -1500 DA like we get up here in the late fall, you'd hit way better times for sure of course.
