Just got my issue in the mail today, and they test the new "Track Heat" intake on a bone stock GT.
Interesting results:
At 1900, there's only 3.2HP gain but 158.12 TQ (max tq gain)
At 5300, 20.06HP gain but -1.42 TQ (max HP was at 6k, +22.06)
Discuss....
Maybe I'm reading it wrong but that info seems contradicting.
In the listing, 5300 shows this..
rpm---base----base-----trick-----trick------diff-----diff
---------hp-------tq-------flow-----flow-------hp-----tq
5300 228.93 226.86 248.99 246.74 20.06 19.88
Seems the gain on hp is correct but the torque is not. Which maybe was a typo of some sort so, forgive me on that part. Either way, I still remain skeptical. The runner length does not appear to be any where near the same as the stock intake. Which their runner design promotes good low end torque without too much drop off at high end. Although the stock long runner design makes for poor hp capacity in the high rpm's. So it almost seems like they managed to merge the two.
What this magazine test is claiming is that a design similar to the bullitt intake manifold was not only able to produce positive hp and tq gains over stock but sufficiently surpass it. If the numbers are true, then we should all rejoice but, you have to be a tad skeptical. It hardly loses any low end torque and manages to maintain a steady increase on top of still producing a stale yet consistent hp increase until 4800 rpms. Where at 4900 rpm's it starts to seem like it's making it's moneys worth.
Don't get me wrong, kudos to Trick Flow if they just pulled off the practically improbable to the 2V crowd. I'll look forward to having one on my car some day. If the gains are real.
