EFI manifolds
Hey guys. This is my very first post here on ThirdGen.org!!!
Questions,
1- Which intake manifold setup do you all prefer for a blown application, Accel Super Ram, TPIS Mini Ram, or a single plane carb style intake w/ welded in injector bosses and a 4 barrel throttle body?
2- In reference to question #1, why?
3- Which EFI setup, Electromotive TEC-2, Accel DFI, or Speed Pro SEFI8LO?
4- In reference to question #3, why?
Im asking because Im about to start working on something VERY NASTY and since you guys seem to have experience with these products, I would like to get some insight and comments before I sign a deal with the devil (just kidding) and put myself into MAJOR DEBT (not kidding).
Thanks...

1) I prefer a carb style EFI manifold.
2) I have used all the mentioned manifolds in that order. Super Ram was great for producing torque when I had a mild engine. The Mini Ram kicked butt when my car got faster and blown. I am presently running a Pro Ram. I chose this because I will be higher in the rpm scale and there is a direct path straight down to my heads for air to flow. The Super and Mini have to channel air through a forward-facing throttle body, which means air flows at a 90-degree or so path, which can reduce velocity. Velocity is important in a boosted application...
3) Out of those listed, use the Speed-Pro.
4) It offers a wide-band O2 sensor, ease of setup and WOT tuning. It also can handle low-impedance injectors, i.e. BIG. I would prefer that you wait for the Gen 7.0 DFI to come out this month. It offers Speed-Pro features plus multistage nitrous control, better part-throttle tuning, and a lower price.

i agree with GMI FAST, if you are looking to go fast and use it with boost. use a carb style intake and convert.
also, i would say wait for the new DFI to come out and compare the both speed pro and the DFI. also, there is some pics of the new DFI on accells webpage you can look at.
