fast 102 vs btr equalizer?
fast 102 vs btr equalizer? Does anybody have a dyno graph of a comparison between these 2 intakes? Also the combination that I'm looking at possibly putting this on would be TFS 215 heads and 235/239 cam shifting at a max of 7400.
Those are two drastically difference intakes and the power bands are going to be completely different.

I would think with that cam and high rpm desire, the MSD Atomic would provide better overall power than BTR which is more for 5k up power band. Just my 2 cents

I remember watching this video at one point, thought it was interesting, Don't know if this is a fluke or what but I imagine a LS1 with HCI would show similar results. I would talk to Tony Mamo and see if one of his offerings would be a good fit, he's a straight shooter and won't sell you something you don't need.

For cathedral port heads, I'm pretty sure the Fast 102 doesn't have adjustable runner length. This setup might be better off with the MSD intake. I think the BTR is either all high end or needs forced induction.

You're right. I keep forgetting for rectangle port yes, but not for cathedral. Thank you. Edited and corrected.

Interesting fact......Of ALL the composite intakes on the market that I port (FAST and MSD), I remove the most plastic from an MSD cathedral intake. It needs major surgery to be at its best
Without doing so it just doesnt have the proper cross section to be as effective up top and having a shorter runner than the FAST its already compromised in what it can produce in the low and midrange.
This dyno test thread is older but nothing has changed and it clearly shows the difference between the FAST and the MSD (both ported and optimized by Mamo Motorsports).

If the BTR Equalizer was in this test it would lose even more down low and start working even later.....that intake has a very short runners and its only about high RPM power and it will hurt midrange torque production a great deal.
If your not turning 8K dont even think about it......if your building a 7500 RPM piece you could consider the ported MSD but understand you give up power below 6500 when compared to the FAST (not as big a loss as the BTR piece however).
Shorter runner intakes are ALWAYS a compromise......the shorter the runners the larger the compromise you make and you do give up a lot for that extra bit of power in a narrow RPM band up top
BUT....for a race car that maybe always see that narrow RPM band, a shorter runner manifold may be the best choice.
Not so much in your typical 7000 RPM ish street /strip Hydraulic roller set-up.....in that application the ported FAST 102 is still KING!!
BTW....we are discussing a cathedral application ONLY. (In an LS7 application the ported MSD actually trounces the ported FAST across the entire curve by a significant margin)
Hope this helps

Equalizer is a little short for all but the most radical NA cars. Works better for boosted cars. If your limited with the f body packaging, I would look into an ls3 top end with the high hp fast runners ported by someone like Tony mamo or ws6store.
If you are not limited with fitment, the fabricated sniper intake would be worth looking into.
If your set on a cathedral setup and limited to f body fitment constraints, it becomes much more difficult to build a car that breathes well from 6500+. I would use a mamo ported MSD in this case.
