Pull the trigger on 12psi, injectors, and EMS. You'll be happy you did. If you really want 10psi I have an extra pulley & belt if interested.

 

Or Just Call ASP, Order a 3.0' (14psi) Pulley

 

^ Remember, the OP has a Vortech. Those pulley sizes you mentioned will make way way more than 12 or 14psi.

 

No no problems yet. I I do have the head gasket and waiting when I decide to go with 14 psi..I think you will be more than happy with 12 psi

 

Ohhh My Bad, i though its was a Novi1000 we were talking about!

My Bad! jejej Novi1000 owner here So i dont Know Shit bout Vortech! lol

 

to all ... Not to highjack your thread 5power.But on a comptech
blower how small of a pulley could one run safely.With the aid of ems,injectors,
good tune and stock internals?


Thanks

 

Boom Chicka wah wah....haha I just order rc750 injectors, 12psi seems to be the consensus. Is going from 10psi to 12psi a huge noticeable difference? I wanna go 12psi but not knowing any well known tuners in Northeast Ohio is making me nervous without the headgasket... But seems like everyone is running awesome over 10psi without it.

Now I need a map sensor...GM or AEM Map Sensor? I also need to get plugs thinking about NGK 7173? Other than that I should be ready to go right?


sazukabluz highjack away

 

I'm running 3.5" pulley on my comptech, it gives about 10.5 psi at 9200.

A couple more psi would be nice but its running 100% now so I'll leave it alone, plus the tuner only comes to the UK about 2-3 times a year.

 

you don't need a map sensor. the factory one is good up to 13psi

 

Actually, the stock MAP sensor is good up to 10.94psi per EMS. I ran 10.5psi on the stock map sensor with no problems.
