Sounds like its time for either an Edelbrock Pro-Flow or Holley Hi-Ram!!!

In any case, it sucks to hear you're having such problems with the FAST unit being as expensive they are.

 

nah im going to probably do a TBSS/NNBS 90MM setup you loose a ton of low end grunt with the Edelbrock pro-flow dosent start to make power until 3500 to 4000 grand i dont really know to much about the Holley most likely same results since they look identical.

 

Did you have trouble lining up the 10 mounting holes? Mine where a little off.

 

only one of them gave me a problem but it was doing it even with my stock truck intake

 

Well I put a evap smoke machine on the truck last night and my NW92 TB is leaking at the throttle shaft

Also the intake is not leaking around we're the two halves meet or anywhere else so I can rule that out.

 

Good to hear that. So what's your next plan.

 

I feel your pain bro. I was almost at the same point as you back in April. After weeks on trouble shooting, logging, swapping gaskets, injector o-rings, redecking the port surface on the intake,........I was at wits end and then I by passed the factory PCV system. Instead of pulling vacuum from the drivers side of the manifold to the drivers side valve cover rear port, I installed two catch cans and pulled vacuum from the valley cover front port and moved the brake booster hose from the rear of the manifold to the drivers side. This cured all the gremilings that I had been so upset about.

 

Post some pics, always better with a visual. Lol

 

Yes please do that would help out a lot

 

That is interesting.
