Trick Flow intake manifold flow numbers
Thanks for the input...I've seen that test from back in 96 (I think it's called "Intake Overload" its got really good info. The 245 cfm does seem high (considering the Performer is 228 cfm peak) until you look at the port size for the Trick flow its a whopping 2.4 in2 compared to the Edelbrok Performers 1.94 in2. Thus...There is also a big difference between the cfm/in2 ratio (translates to air velocity). The Performer has smaller ports, but manages lots of flow, this means better air velocity. If you just look at this, the Performer has a huge edge (114cfm/in2 (Perf) vs. 102cfm/in2 (TF)), which I would for sure think would improve low end torque.....BUT the Trick flow uses 15" runners, compared to the Performers 12", which again swings the torque back to the Trick flow, by changing the sound pulse reverberation timing.......You are definetly right a Dyno test would be great to see. I have a funny feeling the Performer would slightly come out on top, but the price of the Trick flow is very attractive. I read the article on the Performer RPM also, I'm not sure I like the manifold for the application I'm doing (its more high RPM based), It doesn't have really anymore low range grunt than the original RPM, and the original RPM has a tendency to make mild combos feel slushy until about 3 grand. Now if only Edelbrock could redesign the Performer to use the same "Y" concept as the RPM II, than I think we'd have a winner.....I wonder if any Edelbrock exec's read this forum??[img]/phpBB/images/smiles/icon_razz.gif[/img]
