Can 450+ rwhp be done N/A on a 4.6L 3V????

[*JZ*]

Discuss.....

NO STROKER
STOCK INTAKE MANIFOLD
4.6L 3V
.020 over
heads
cams
bolt-on's
longtubes
etc....

Compression obviously is a must...

 

[classix_stang289]

i have no clue lol. is this trying to be had with stock compression?

figure i say something at least lol

I was expecting a dyno sheet and information on a car you just built or something.. Hah.

 

[05yellowgt]

Are the only requirements stock displacement with 3v heads and staying n/a? Sure it can be done with enough compression, octane, and the right set of heads cams and intake.

Any Compression
All Motor...

 

[05yellowgt]

Stock intake manifold will make it harder. I'm wondering if you put that as a requirement for a reason, as in you have a car somewhere that has done it......

 

[AJ]

keeping it streetable and the stock intake manifold on a mustang dyno.... no

I say it is possible, but very expensive vs. the power adder quick fix.

Maybe

I say no with the stock intake and pump fuel.

VP Street Blaze 103 or C-16

10.5:1or 11:1 compression, max ported heads, bigger valves, full acessory delete, stage 3 or better cams, pullies, electric water pump, full 3" exhaust, .020 overbore, on 116 octane. if its not 450 its getting damn close.

We shall see

116 octane on said motor above and you're going to lose hp.

10.5 or even 11:1 compression doesn't require much octane on an n/a motor. You could probably run that on 91, or atleast with a gallon or two of 100 mixed in. I'd think it'll take somewhere north of 13:1 or 14:1 compression to reach the 450 rwh mark with the components listed.

As for the question, I'd say it's possible, but probably not real street friendly.

Definitely not street friendly. This would be for drag purpose only.

 

[rojizostang]

here's what i was looking for....what kind of hp is this guy making?

Then yes, IMO.

With enough compression, killer heads, killer cams, lots of RPM, and the right supporting components, yes.

 

[irishpwr46]

when you say it like that i say push 14:1. ^

 

[stkjock]

ok, so say its doable... WTF is the point?

the cost and lack of street use makes it worthless IMHO. Blower @ 10-12 psi 450-500 whp, simple, easy and street/strip friendly....

K.I.S.S.

 

[Bingo]

Probably gotta spin it to 8000 RPM.
