i didntt really think his intake is choking me at first either. but i didnt think the camshaft advance would have such a great affect. and know people have great luck with thumper and tmoss stuff. so i got confused.
i still cant figure out why the car didnt trap more than it did before with the stock engine.
with a bone stock 140k longblock, CAI, pullies, 1.7 RRs, exhaust and gears with a DR i managed 14.1@99 with a 2.0 60' and 13.9@ 97 with a 1.9 60' were my best with the stock engine.
on me new combo. i added
thumper e7s
tmoss lower
port matched my own upper and opened to 70mm TB
B-cam which i advanced 4 degress
70 MM TB
73MM MAF
190lph with aj regulator ( doesnt affect power but i can tinker with stuff)
all on top of a fresh rebuilt shortblock and a smoother shifting trans i just got rebuilt
granted i was just on street tires this past weekend and managed the 14.2, but it didnt want to mph at all, with a good tire i bet i would have seen 13.7 or so. but i always thought the mph will decrease a tad bit when you hook better.
all in all i would have guessed i would gain at least some mph in the 1/4 mile even if i was on street tires. i didnt gain anything.
just a reminder my car made 225HP and 270 TQ on a mustang dyno.like i said before, nothing is mechanically wrong. AFR was dead on on the dyno, consistant 13:1 pretty much, checked compression and got b/w 140-145 on all 8 cyls.
and another thing, i have a friend with a 97 GT mustang, SOHC 4.6 with a
K&N filter and hpipe and flows on the same dyno made 207 HP and 270 TQ
i figured everything i have done to my engine and having it being new, that it would make more than just 17-20 Hp more than a sohc 4.6 with over 100k miles and he managed to make the same TQ number
heres the dyno sheet of my best run. maybe u guys can see something....
i really dont feel like tearing it down and upgrading, the engine runs good. i would be very willing to go back in and mess with the came timing for sure. but i dont really have the funds to really upgrade stuff. i dont know if mine is running bad or what. maybe its fine and i am crazy, but it still gained no mph, maybe i just need a tire to hook good. because i was pretty much launching off idle. anything more would spin the tires hard.
