About 15 rwhp

 

[fastgtfairlane]

thats not bad.

 

[Jrgunn5150]

in SOTP terms, it's very effective.

About 15 rwhp

with tune... mine with out a tune gained like 4 rwhp and lost tq down low but gained like 7 wtq up top

 

[Jrgunn5150]

Mine picked up 15 rwhp without a tune.

Mine picked up 15 rwhp without a tune.

maybe its an anti south east thing. b/c none around here picked up more than 6 rwhp from it on the dyno.

 

[fastgtfairlane]

im sure with more mods its worth more power. what all was done to both of your cars? 7 and 16 rwhp is a big varience for the same intake manifold.

 

[Jrgunn5150]

No air silencer, mid pipe, catback.

 

[voidfinger]

no silencer, mac o/r prochamber, and mac cat back. :dunno:

 

[Jrgunn5150]

Well, I never dyno'd stock, I'm just going off the 175 to 185 everyone else got. Maybe there was something weird with my car. It was supa fly

 

[fastgtfairlane]

what about the plenum and tb too. i would think that would help out too. i dont know much about the 4.6s as i have the 5.0

 

[Jrgunn5150]

They aren't much of a restriction until you get into some serious internal mods, or FI

 

[voidfinger]

after pi head swap it helps out some. But yea, i dynoed stock around 175 rwhp... then after all those mods and the intake... i'm at the numbers listed in my sig... i don't know if it was going bad then but about a month after my drivers side upper o2 went out and the tranny shit out on me... so they might have been the problems too... but after replaceing i don't feel much of a SOTP feel. Maybe the intake would show a lot more with pi cams and a tune... i'm thinking the npi cams don't move enough air up top to use the extra volume.

if i made them, it would be out of aluminum more than likely. i'll have to price out material sometime. im just kinda busy now with school and work. i havent figured out how to make the transition or ramp from npi to pi. i may have to tinker around with a fouth axis(never done that) to get the results i want. it'll take some time to make a program since im a newbie to it. i would think that for 100-150 bucks or so a pair i could make a better quality cnc product. it may be too expensive for me to produce a bunch at once. i'll def. look into pricing stuff. no promises that it will happen.

If you make them in the next couple of months, I would definitly buy a set.

NPI cams are spec'd like lame-o stock normal cams in any motor. PI cams on the other hand, are spec'd like a mild performance cam, almost an "rv" cam if you will.

The real hold back initially is the intake though, as we all know.

well i will post up if i end up making sets, but it will more than likely be a while (prob. around spring if it happens?). all the mills are tied up with work right now, and im to busy with work and school to do much at the moment with it. we are so far behind at work my dad said we may need to work sunday :tickedoff: .
