powerdyne project help ive picked up a powerdyne bd-11a and rebuilt it with new bearings and belt but need some help figuring a few things out.
1. What size injectors do i need to run up to 10 psi not planing on running that mutch right now.
2. What cam would work best with the blower?
3. what valve springs are the best for boost?
4. How mutch lift on rocker arms are best .5 or .6?
5. Which head gasket is best for boost?
Ive got on way a walbro 400lph for fuel andjust got done gasket matching porting the heads and intake manifold and slaped a 58mm Tb which is portmatched on the intake mainfold.\
Let me know what you think but dont be a bung hole pleazz

I am no expert so take my advise as such. but I had looked into doing the same set up a few years back.
I went with a baby cam 227 and 918 springs from Crane with 1.7rr, headers, CAI, mildly ported heads and intake. The 227 is more a tq cam then a high rev hp cam. The powerdyne is said to work well with this cam. The set up I was going for was 375hp crank n/a and another 100 crank with the powerdyne. BTW 10psi will be very difficult with that unit. I ended up doing the engine mods then going spray.

Getting a custom cam made specifically for your setup will always be the best bet. Lloyd Elliot and advanced inductions are the best hands down and they will also set you up with the proper valvetrain to support your cam. Although, an off the shelf cam would work as well, hope this helps.
