Procharger and 4 bolt heads Ok guys I've seen a lot of turbo 4 bolt heads putting down 11xxwhp or even more, running mid to low 8's. I can't seem to find many doing the same with a procharger? I know cylinder pressure caused by torque will lift the heads and making power in higher rpm helps a bunch.
So what's your guys thought on a procharger setup to survive on 4 bolt heads over 1000whp? Would it be wise to run a f1x over a f1a94 to soften the low/mid range some to help?? Or is it time I give up and go turbo... An aftermarket block isn't in the budget. A 370 is or even an aluminum 5.3 is. Will be reusing my prc 225heads, e85, have the alky dual nozzles kit still if would benefit any, 6" chisled intercooler, etc. Will stay t56 magnum for at least a year (if I stay procharger) and possibly go auto after a season. This is a fun street car but I'm looking to knock out a good et. Once I'd swap to an auto I'd like under 8.5's. Thanks

Lost dyno sheet but i thing i was 550 tor by 3k 900 at tor curve.
It is slightly harder with a procharger because to make the same power as say a turbo set up, you have to make probably 100-200 HP more at the engine to overcome the parasitic drag of turning the centri via the belt. But all in all you can absolutely do it and there are quite a few people out there doing it with centri blowers. They're just not as visible as all the turbo stuff, but that doesn't mean they aren't out there. You can definitely make as much power as you want with a big procharger and 4 bolt heads. It's all in the tune.

I have seen a couple on youtube that were running low 8's, even high 7's but they don't give all the details besides the CI. Talked to 3 shops and 2 were on opposite sides and one was right in the middle for what they thought about it lol.
