Smog pump supercharger

Why not use an old valve with a weak spring? Or just the weight of the valve...add washers to adjust your boost?

I thought about that but a bag of springs the ball valve etc..

I thought about shaving the fins and tapping the block on the intake side and screwing the regulator pictured above directly into the side of the intake port so all the load is dumped right before the valve.

Basically a prototype of a 14 year old prototype. So I’m not sure what I’m gonna do yet.

The pump is good. Stripped it and parts come out looking like picture #1 everything Is so filthy. They appear to clean up well as shown in picture #2 and #3

 

[Thepaetsguy]

Bad lighting best picture I can get the rotors cleaned up better then I hoped so that’s a major plus

 

[Thepaetsguy]

Pump cleaned up well I’ll use it or try..

 

[Thepaetsguy]

Pump is back together and no abnormal noises spins free greased etc.. Inlet and a pwk 26mm kit with the double clamp boot will fit perfectly! I was worried about the pump intake port being to big for the boot. Not the case! This pump moves a lot of air just spinning it up lightly.

It’s looking a lot like I have to cut/move one tab drill a new hole and it’s bolted on a mount.

I have SBC generator tensioner arms I can use I think it would be perfect! I might need a 3hp flywheel good thing I have two billet ones! Even better both the I/C 5hp’s have a pulley already bolted to the starter clutch!

There is no welds on this bracket did they epoxy it together?? It will not separate.

 

[sparkwizard]

Mine had 2 spot welds that I drilled out. Pain in the rear end.

The person at the factory needs a raise cause that spot weld was amazingly tuff...

I got it

 

[Thepaetsguy]

Dang it! Close but no cigar i’m making my own bracket out of plate steel. the pulleys almost line up as is... Well the flywheel doesn’t hit so that’s good!

 

[Thepaetsguy]

I wonder if I can use this bracket and space the pulley out more? Again only time has that answer..

My idea above worked out dang flawless! No new brackets just some washers..

 

[sparkwizard]

Don't you have any offset belts about that size?

 

[Mr. Pink]

Don't you have any offset belts about that size?

First glance thought you said offset bolts.

 

[Thepaetsguy]

Heck ya I don’t want to say stuff is to predictable but that sbc generator tensioner worked a treat!

You do know that with a draw through system, and pressure relief, or blow off gas is explosive and should be safely routed to the exhaust system, right?

I had this crazy scenario In my head of the pressure relief popping open and going full combustible sprinkler but Absolutely I will try to find a route or way to route the wastegate safely.

 

[sparkwizard]

I was serious about routing it to exhaust where it could burn up safely.

Before I go starting this little 5hp I am going to iron out every detail I can. I’m working on a belt. And will absolutely route any wastegate pressure to the exhaust pipe. It’s very nicely mounted in my opinion but I still have much to do.
