intake

[cbarr300]

OK guys, here's the combo.

forged 306
vortech s-trim about to have a 2.95 pulley w/ stock crank
meth/water injection
powerpipe
windsor jr. heads (180 cc runners) w/ slight port and polish
cobra upper/lower with a slight port and polish
custom ground blower cam (.536 lift..I'm not sure of the other specs)
1.6 RR
3.73 gears
11.5 a/f before meth injection and 10.6 after (comes full on at 5 psi)
running 22* of total timing (I could run a good bit more)
supporting mods/extra things


My car feels like it has a LOT of torque down low...but it just doesn't rev up very fast (dyno day on saturday so I'll actually see what my curve looks like.

Up top (past 3500) the thing pulls like a raped ape...but could definitely be faster

I know my heads are kinda killing me..but how bad do you think the intake is hurting me?

what would be your opinions on a trackheat intake with the current setup? Also, what intake would you recommend. It's a daily driver and sees the track every once in a while....so I'm thinking that maybe the street heat would be better for my app.


thanks for the time

Subscribing. Be sure to post up your dyno sheet when you get it.

Tmoss could probably tell you a good deal about what your intake is or isn't doing for you.

Oh you know it...I've been waiting forever to get this thing on the dyno.

It's still gonna have the 3.33 blower pulley and will be ran on a conservative tune.

I'm shooting for ~350 with nice curves...any more is icing for me.

Generally speaking a shorter runner would be better IMHO

Now ... considering you force things

I would have to believe that is all the more true

I'd look at no less than TFS track heat
or
Edel rpm/rpmII

As for the shortest runner offerings .....................
I'd not tell you to run out and buy one
but
I'd be looking for combos like yours that had them for some data
before
Making my final decision with this matter

Hey ... Considering don't cost cash

I'd say the Cobra is choking you at the big end
and
With a greater degree since you move so much air up there being forced

I have a Street Heat intake on my setup, (see sig) and I still managed to squeak off 497rwhp on the dyno. That was with a 3.33" pulley on the vortech making about 10 PSI.
I would imagine something like the Track Heat or like Grady said the RPM/RPMII would perform even better for you. .

ok guys, another quick question...does wal-mart sell that HEET gas line stuff?

When I get on the dyno this saturday I wanna up the meth content a bit and run a bit higher timing. I'm currently using a windshield wiper fluid that's about 20/80 meth to water content...which isn't all too great but the best I could find.

If wal-mart doesn't sell it, any other places that might...I'd imagine any local car place would have it and I'm gonna pick it up tomorrow.

I was just doing a little surfing around, and I found this article that compared 11 different intakes on the Anderson Ford Motorsports dynojet.

I don't see how that test is all that valid for us here as it is na
and we are talking about a blown combo in this discussion.

I'm thinking that a trackheat will really help.

I also think that, for my combo, the effective rpm range for that intake will be moved down somewhat (since I'm forcing more air in). I'm also changing the blower pulley in the next month from a 3.33 to a 2.95. I think this will move the rpm range down even further.

That is why I asked if a cobra intake (slight port and polish) is holding me back. It would seem that with extra airflow, the intake would be maxed out sooner than it would be if n/a.

I can feel my power kinda drop at 4800 and up....Boost is still slowly going up.

also...DYNO DAY TOMORROW!!!!!

now I'll finally know what this thing is putting out I'll also be using the dyno pulls to try and tune for my meth injection a bit better.

i don't know man, the holley intake is simply better than the rest
