so who is spinning their procharger with a smaller pulley set up and venting out extra boost to make max boost earlier? Whats the easiest way to do this? Is there a inline WG that can be added or is the boost controller trick the way its done? Im up in the air about turbo and procharging and max boost at max rpm is one of the main downfalls against procharger for me.

What size pro you looking at ? With mine I'm glad the boost ramps up with slick i still over power the tires I would do a waste gate to vent out the over boost it's what I'm going to do if I setup to the next size blower

I dont want anything too radical, I was thinking if I pulley a D1SC to run like 16-17psi of boost but have a wg vented out at around 8 psi I would hit 8 psi at around 3-4k rpm and hold it to redline instead of hitting 8 psi max boost at 6k rpm. So it would act very similar to a turbo. Then later once I get my block built I could do the same thing, overspin the blower to around 20psi then vent it to around 15-17.

would there be any downfall to doing this?

I was thinking about something along the same theory as this earlier this week...well, sort of. If you wanted to make 10 psi at 6,000rpms, would there be a way to pulley the blower to acheive, say, 12 psi at 6500rpm and then just short shift it? That way you're making more boost earlier?

the only down fall I can see is for people who are up higher in the power levels who would have to overspin their blower to achieve said effect. In which case they should just go to the next blower size up.

yea but this way you can have 10psi at 3-4k and keep it till 6k rpm. In theory this should create more power under the curve, leading to faster et's...

The down fall is the fact that the blower will be heating the air more for you to accomplish this and it will take more HP to drive the blower. There are a few articles on using wastegates to have adj boost with a supercharger, but not the normal issue as I just use my right foot to limit the power. It isn't as consistent probably, but pretty repeatable with a little practice if you understand what I am talking about. GL with that project it can work though.

yea true, I can see more heat as a result. Would the big EPP front mount suffice to cover this heat gain? And Im not really trying to limit power as much as I am trying to limit boost lol I dont want to blow the stock block just yet plus I am hoping to be able to increase usable boost at the same time.

Meth?

Limiting boost or limiting HP is basicly the same thing as one helps or hurts the other.

Restrictor Plate

I understand regulating boost takes away from potential HP. But regulating power with your foot is completely different than what Im getting at. I want to be at full power, which I want to be only at 8psi. But I want to get there earlier in the powerband than at redline. I want to mash the gas build 8 psi at 3-4k rpm and let the wg vent out the rest keeping me at 8 psi throughout the rpm. I know somebody has to have this done already. I was just trying to find out if there is an easier way to accomplish this than running wg and boost controller together.

no, doesnt help increase under the curve power. Just helps to keep engine from detonating. That could help from blowing the engine though but I believe with a proper set up you shouldnt need meth.

restrictor plate? a throttle restrictor? wouldnt I still reach max rpm and hit max boost? That would be bad if I pullied for 17psi. Or are you talking about a restrictor thats in the intake that limits airflow? If thats the case then would that work if I was pullied for that much boost?
