This is my Winter project, I found a Holley Pro Dominator W2 Tunnel Ram from a member here earlier this year. I recently just sent it off to 417Motorsports in Springfield MO to get it changed over for Port EFI. I am hoping to find some power from the tunnel ram and the additional CFM.

It is going on the W2 R1 416 that my Dad and I built for Drag week. It has shady dell ported W2s and a comp solid roller with 10:1 compression. It has been a best of 10.83@124@3600lbs. It is still pulling some vacuum on the 1000CFM 4150 throttle body so I am hoping for some improvement just from the CFM addition alone, we will see. Jess Sias another drag weaker was pulling similar vacuum(4-6KPA) on a 4150 throttle body, he switched to a 4500 throttle body and picked up 30 horsepower on a 650 horsepower combo-that would be a nice gain we will see.

I hope to gain some power from the tunnel ram, some ET from losing the heavy bondo filled stock hood, and some more power from drawing fresh air. It sounds great on paper!

Sorry about the sideways pictures seems to happen randomly.
