I have a Vortech V3 on a 04 350z, tuned with Orsiris and with DW 600cc injectors.
Everytime I start the car I need to give a little gas or else it would die, but this morning I forgot to give a little gas and it die, and won't let me start at all after that, any suggestion plz, thanks!

Hi! Let me start off by saying very informative, I've only read about 1/3 of the post, I plan on once I have the time finishing reading the rest. But let me get to the meat and patotoes of it, I'm picking up a used vortech for a non rev up in a few days. It doesn't come with injectors, and I opted to not get the black box with it as I plan on going with Osiris, but if I'm using the stock pulley will I need to upgrade my injectors and fuel pump? I'm not planning on swapping out the pulley till I build the engine. Also what should I check for for wear and tear? I'm not in a rush to put it on and I plan on getting the air fuel gauge, oil temp, and boost gauge and using the greddy oil pan for the return lines and oil temp gauge. I have the kinetix intake manifold, z1 test pipes, motordyne y pipe, and nismo cat...err y back exhaust, I plan on Crawford headers, and the motordyne art pipes when I get the headers and a over bored throttle body. But will the injectors and fuel pump be able to handle low 300hp or is it better to just upgrade now? The only thing I plan on after the headers, art pipes, and throttle body is a electronic 3 inch cut out after the y pipe, and possibly switching the piping diameter too 80mm.

this is the proper order for building
1.fuel system
2.gauges
3.FI
4.anything else
do not spend a dollar on exhaust headers etc until you have fuel pump and injectors.

My pride has taken a hit for the question that I'm about to ask, so I apologize up front! However, I'm about to order the 928 impeller and for the life of me I cant recall the rotation of the impeller! I want to say it's spins clockwise, but I'm not sure and car is not with me right now.

Threads is correct CCW... Seems a bit counter intuitive as you watch the belt it seems to turn CW but here is a pic to put your mind at ease from 928's site.
Compare the volute in pic w/ yours... Have to turn it upside down in your mind with the way it sits in the car: http://www.928motorsports.com/parts/...h_impeller.php

While I agree with getting a larger crank pulley first for more belt wrap, I wouldn't necessarily say that all the 2.62 pulley does is slip. FWIW, I've used the 2.62 pulley, and my boost graph was still linear until redline. Now, was there belt slip? I'm sure there was, but the vehicle still made more boost than with a larger pulley.

I finally fixed the belt squeal/slip and accellerated belt wear issue
If we didn't ALL fight this issue, I'd consider this a shameless self plug. However, since everyone with a non-revup Vortech kit WILL experience slip, squeal, and belt problems due to improper tension and a crappy stock design, it's more to help than it is to self promote.

A serpentine belt is designed to slip so it doesn't damage the drive components. That is the whole point behind it. The stock design isn't crappy because it's only designed for around 400hp. Anything more then vortech uses thicker belts like they do on the kits for domestics. 8 or 10 rib belts are for higher hp application. I personally think they designed it quite well for what the supercharger was made to do.

This was fix by TimRod's Vortech Belt Slip/ Noise Solution in 2004
