well folks, i humbly tuck my tail. i was wrong. the gt intake may be the best on paper, but the boss intake pulled it off this weekend.
to recap, i blew my gt motor and replaced it with a boss motor. i had dyno tuning done with the gt and boss intakes. the gt made 429rwhp/413rwtq. the boss made 441rwhp/387rwtq. on paper, the gt intake gives up only 12hp to gain 26tq. actually, the torque gains were as high as +33 along the curve, but none of that matters any more...i have seen the light!
so, 2 days before SVTSuperfest, my 5th gear synchro died. I decided to go anyhow and just work on my line and play miata for a weekend (corner carver with no straight line speed). on friday, i ran my gt intake, as i normally would on any given day. i was stuck in the 2:18/lap range with top speed of around 120. i tried to get the engine to rpm as much as possible in 4th, but couldn't get more than 115mph@7200rpm (and it was a struggle to get it there) and then dumping to 6th only allowed 5 more mph. saturday, i waffled back and forth, whether to try out the boss intake or leave well enough alone. my friend sean said to just go for it, so i did. WOW, what a difference!
the power curve of the boss intake is almost flat as a board from 6.5k to 8k. with 430rwhp at 6.5k, peaking at 441 at 7.4k and holding that peak to 7.7k, then falling back to 430 at 8k. thats just a lot of high rpm range to work with and it showed. i was able to easily reach 132mph@8000rpm in 4th gear and then dump to 6th to bog its way to 140mph climbing the back straight. with this and a bit more familiarity with the track, i clicked off consistant 2:11's with a best of 2:10.29.
so, while the gt intake torque curve is very desireable over the boss' for wheel to wheel racing, where you find yourself out of the optimum rpm range quite often, the boss intake offers max effort for "qualifying laps", which i have found out is exactly what time trials has been like.
i am a convert! rpm is king! can't wait to see what personal best i can come up with once 5th gear is restored!
just a note: if i was stuck with 7500rpm, as a lot of you hold to (whether by stock tune limits or mental barrier), the results would not have been as glorious. the magic is at 8000rpm, my friends!
