I've got some stupid-big injectors and need more air. Specifically way-down low in the engine RPM. The heap is currently NOT driver friendly when it comes to controlling no to low boost smoke (this is NOT an AFC thing
![Wink ;)](./images/smilies/icon_wink.gif)
Currently, the heap's Charge-Air circuit amounts to:
- Custom oiled-gause air filter in a 100% true cold air intake.
- 4" tube from the filter to the primary turbo.
- PDR HT3B primary with the 23" exhaust housing (I think it's 23).
- 3" tube from primary turbo to secondary turbo.
- PDR custom S362 secondary with a 14" exhaust housing with the dual puck internal WG.
- 3" tubing from secondary turbo to IC.
- Custom Hellman after-cooler (no more than 3psig pressure drop from secondary to head, at full song).
- 3" tubing from IC to Twin-Ram type intake feedhorn.
- PDR ported head (195cfm IN / 220 EX)
- Hamilton 188/220 cam, etc . .
- Early ATP 3-piece exhaust manifold.
- "Cobra-Head" hot-pipe.
- 4" down-pipe to just past the transfer-case and 5" on back.
Looking for suggestions as to how to make it spool MUCH quicker off idle. Different secondary such as a ball-bearing unit? Small(er) exhaust housing with an external WG on the manifold? Ball-bearing primary? All three?
A little more air on the top-end would help keeping the EGTs down as well.

Basic low-buck options all the way up to Drool caliber . . . .. what would you suggest?

BTW: Honestly, I know squat about the A/Rs and all the different compressor/turbine wheel sizes. I read many of the threads here and there. Most are suited to the higher RPM fueled engines, not VE stuff. I do understand how the mess works, but when it comes to, by design, dialing-in the right component selection, I'm lost at this point. I'd rather spend the money once (again
