i have the 2.7" powerdyne pulley ready do go in along with begger injectors. this pulley is said to make 9psi, does anyone see any problems with this set-up, i think i should be fine. thanks

 

You should be just fine with that. What size injectors are you going with? I would go with 43lb's and ditch the FMU. Just make sure you get the belt good and tight.

 

the bypass valve that came with the kit is only good for about 6 psi, it wont last long at 9,
so start hunting for a better BOV.
42 lbs injectors will work just fine at 9 psi.
find a local shop and do a dyno tune, after it is all done go hunting for a hemi and have some fun.

 

What type of BOV do you have Pappydan? For some reason, I don't think mine is working right.

 

If it is "supposed" to have 9 psi then it will prob be around 6, at least that has been my experience with Powerdyne. Get the boost up around 8 or 9 psi, get the tune right, and I think you will be happy with the results-the Powerdyne heats the air far less than some other blowers and it is capable of making some good power.

 

Thats exactly my problem also. I got the 9psi pulley and only see 6psi. Whats the problem?

 

i am going to run 36lb pontiac gtp injectors, thats what the guy told me to use that is going to tune my car. which BOV are you using at this PSI, and are they hard to swap out, do they perform better? thanks

 

Mine is the original one that came with the kit. I never here it blowing off any pressure. I'm wondering if it is bad already.

 

anybody have thoughts? ttt..

 

you will be ok, but an injector upgrade is definately needed. 36's would be fine for what you are doing, just don't try to run the truck without tuning for the new injectors.
