I just swapped the cobra intake for a track heat intake, 1" spacer, 30# injectors, and a new pro-m 75mm MAF. I haven't really driven it too much but I know I still need to work out some of the tuning bugs but it seems slower now. I haven't really gone past 4500 rpms yet though, is this going to be one of those high rpm only intakes. I was expecting it to be a high rpm intake but I really didn't think it would hurt my low rpm power/torque too much. Do you think it is just a tuning problem or is that just the way this intake is? Any suggestions would be appreciated, thanks.

I think the the problem is the #30s. They r way to big for a na engine. Try stock or #24s max.

Please try and have somewhat of a clue before posting an answer. If you don't know what you're talking about, don't post answers. :rolleyes:



Erik, the Track Heat is definitely going to be stronger above 4500 rpm. You shouldn't lose a noticable amount below that IMO. I ran a Track Heat before I got my Holley and it felt fine at lower rpm. I'd drive it for a while and really get on it. Once you feel the stronger pull above 4500 you won't worry about low rpm torque.

LOL, yeah that wasn't too good of an answer, I think the 30#'s should work pretty well, I swapped the 24#'s for them in fact.

I sure hope you're right, I guess I'll find out today cause I'm gonna drive the sh*t out of it to try and get it running as best as possible, I think with a little tuning I can get it as strong as the cobra down low and much stronger in the upper range. Thanks for the response.

My combination last year was almost exactly part for part what you have except for 2 things - it was a 306 and I had Flowtech longtubes. It had decent low end (IMO) and pushed my fat vert to mid 12s at 109 mph in Phoenix (DA=2000+). Your extra cubes should help you build more low end than I did. Then again I tend to not notice how the car performs below 3000 rpm or so since I'm more concerned with getting down the track as fast as possible. :)
