Performer VS. Performer RPM

[IMPULSERACING]

I was wondering which upper intake do you guys think will be better for my application. The Edelbrock Performer or the Performer RPM. I know they say the RPM is for upper RPM over 5000 but it also says for Nitrous applications. I will be spraying a 150 shot with the possibility of 200-225. What do you guys think. Thanks in advance
P.S. I shift at 6000-6100.

Performer is made for running from idle to 5500, RPM is 1500 to 6500. If you're shifting at 6000 or 6100 then I'd say get the RPM.

I have the RPM and it's great. I don't know the difference between it and a Performer because I've never ran a Performer. Oh yeah, but there's a slight difference between our engines, mine's carbed. So I can't tell you which one is better for you, but I'd guess the RPM for your application and driving habits.

I can't say anything about which would be better for your setup, but I can tell you that I know a couple of guys who bought RPM's for nearly stock vehicles and did not lose any considerably low end torque.

Thanks Guys, I wanted to switch to the RPM and now I will. It always makes me feel better when other racers agree with me.

By the way I meant a B-CAM with 1.7's
(I think I've been around to much N20)

your shifting to high. have u tried shifting at around 5k? I dont think you will lose any time on your ET, but you will save engine wear.

To my opinion... Perf. RPM worth 15-20 more
HP (naturally asp.) with 6300-6500 RPM
shifting. It souds really free flow to me
, maybe too much for 302CI but enough
for nitro(150 hp)
