ok, thanks for the info. sorry op for derailing your thread a bit.

 

Ok as promised I will discuss a little bit of custom piping I did in my setup...here's what my setup looks like:



All my piping has the stock diameter until the pipe that leads to the MAF tube, which is a 3"-3.5" reducer pipe...



...THAT WAS ORIGINALLY PART OF THE INJEN INTAKE FOR THE 350z



Here are some comparisons of the oem pipe and the Injen pipe:

 

SO, after that pipe is the Threadstone 3.5" maf tube, them I needed a reducer silicone hose from 3.5" to 3" to fit the 3.5" maf tube with the stock vortech 3" tube that leads to the throttle body, so for the silicone reducer I used...



...THE SILICONE HOSE FROM THE INJEN INTAKE KIT AGAIN! This time I cut out the reducer part at the end of the hose...

 

i just cut the tabs off the stock maf tube and put a silicone couple right on the stock maf tube. free and no messing with all those transitions.

 

Stock MAF tube was too small to use the uprev MAF GT (maxing out MAF), which why I switched to the Threadstone 3.5" MAF tube...stock is 2.75"...

I wouldn't have had to this if I kept using the HPX MAF...

 

I have one pipe throttle body to just vehind blower.

Fmic also 3 inch inlet/exit

Intake ironically...
Also 3 inch Injen based.

 

nice ive never seen the bov welded to the fmic!!!

 

holy crap, how did you fit a 3" pipe behind the blower coming up from the intercooler? I barely could fit that smashed version vortech supplies and i think it was like 2" or something.

 

Looks rubber!?? :dunno

 

Couple questions

1. Do you have a built block?

2. Do yo u have any head work like cams porting?

3. What pulley size and cog belt did you use with your 928 impeller to get 500whp?

I have v2 with cosworth manifold, cosworth fuel rail, 600cc injectors. Walbro 255, 2.87 pulley with stock maf. I own a uprev maf gt but didn't need with my setup. I dynoed 355whp and 343wtq on an wad mustang dyno

I just wondering what your did to make 500whp cuz that is my goal on a mustang dyno.

But anyways congrats on those numbers.....

 

Now that is a great achievement! Well done buddy, never thought our V2 is capable of reaching those levels

Just blew my blower and I guess it's time for a proper rebuild with an upgrade

 

1. Yes

2. Yes, head porting, 3 angle valve job and S7R cams (I have a revup)

3. My 500whp dynojet setup had:

2.75 Jackshaft, 30/34 cog setup, and 6.125 Crank pulley (Fluidampr), spinning the 928 impeller up to about ~63k rpm

 

Was this done on a v3 blower?

Is this the most power anyone has made from a VQ block and that particular blower?

 

It was done on a modified V2 blower (impeller was changed to a 928 Motorsports Impeller)

 

I think so, if not #1, #2. Another guy hit 600 too!

Those blowers, with the 928 impeller, are a beast!

 

Must. Get. 928 impeller!

 

Stock v3 blowers are making simliar if not more power per psi. Looks as if Vortech is finally the affordable FI kit for VQs!


I love options...

 

OP, how is this car running?

 

Blew a headgasket due to some issues with my meth; I rebuilt the heads this time with Cosworth HR headgaskets (my original build had oem HR headgaskets)...still breaking in the engine...

I also changed to an even bigger crank pulley, from a Fluidampr to an ATI dampener; hence I'm also going to be changing the blower; although the 928 Impeller is rated to 60krpm (and I had been running it up to +70krpm to hit +600whp) the real limiting factor of the blower are the bearings, which are still rated to oem Vortech specs of 53krpm om the v2 SC trim...while I feel confident the Vortech v2 Sc trim upgraded with a 928 Impeller can handle +500whp @ 60krpm, I can't say the same for sustained runs at +600 whp @ +70krpm...

 

What blower you upgrading to? You going for the V2 TTrim or are you fixing up that YSI?
