Right now I am making 368whp/311wtq on a DD dyno @ function:tuned. On a dynojet I am at 418whp/344wtq on a local dyno. My goal is 450whp on a dynojet, roughly 400whp on a DD dyno. My question is what is my best route to gain it? I am on an '06 revup 350z. First I'll list my current mods: Vortech w/2.87 pulley, Utec, 650cc injectors, ngk plugs, mrev2 & 5/16" spacer, test pipes, Injen ses exhaust, 3.9 final drive, custom larger fmic. I am getting a fuel return and jwt clutch installed as well in the near future before I pursue 450whp.

So the routes that Im thinking of going are either: 28 tooth s/c cog pulley to run more boost (however I wonder if the motor will handle anything above the 11psi that I am running now without headlift or any other harm?)

Or: Headers of some sort, and some head mods?

Im unsure what is the best way to gain 450whp on my setup. I would really like to do the pulley but just unsure if it will hold.

 

I'm at 393 on ForgedPerformance dyno with the 3.12 pulley non-revup. I have Nismo cams and DC Headers. I would suggest the BC Cams & DC Headers, you should see 450whp on a dynojet! I heard the 2.87 snaps belts, have you experienced that yet?

 

how about the si trim wheel for your compressor.

 

I have seen different stories, I say with the non-revup belt routing it will snap belts, but with the correct idler pulley system on the rev-up you should be fine.

 

What kind of EM are you running?? Utec?? If so ditch that and go for a stand alone for a better fine tune and more power!

 

I'm at 396 at 6500 rpms on Forged's DD with the Si blower, 2.87, Utec, injen ses, test pipes, meth, stage 2 RFS. If i ran my dyno out to 7000 rpms like so many of the graphs on here, it would be much over 400.

It would appear that cams are a good upgrade for power, if TSG-Z is making that much power with a 3.12.

So my vote would be cams or a EvoTT exhaust as you are already over spinning your blower at redline as it is.

 

Isnt the UTEC the best piggyback?

 

it is... eagle is used to the best and forgot what entry level is all about lol.... the UTEC is fine for those power levels... of course even with all that tis not that super smooth like a full standalone...but....still for those power levels the utec is fine.
I am not sure on what you need to get your vortech to be at 450whp.

 

You make it sound like I am rich? I dont see you guys selling Oranges and peanuts on the Highway off Ramps to support your Mod habit??

 

LOL Luie, you crack me up!

 

 

I thought you sell all your stuff to me! I want you FCON next, since were talking about EM.

 

go to the shop installs section. one of those jersey cats had MRC tune his vortech to a nice saucy number. heres the link.

zero snapage when i had mine. with the tight belt and gtm pulley mod, i was seeing up to 14psi at 6800rpm+, definately need cams and headers to hit 450

 

I hear that guy has some sick Volk SF Challenges in RMC finish too

 

headers would help....but u do need "some" backpressure....ohh wait that small injen exhaust will give that to ya.....maybe a methanol kit would help ya out.....

 

Never heard of the guy! hope to see you this summer homey!

 

i agree, my car felt faster with nismo exhaust than with my evott.

 

cams, headers, meth injection

 

nitrous?
