obviously you can check the current stuff on vortech's website. All the new ones for the VQ are V3 SCi impellers. Thats superior to all the older V2 SC trim stuff.
There are 3 differnt blower in the legacy line
V1,V2, and the new V3. V1 only has the T-trim. Its has straight cut gears and is a bigger blower than the SC trims.
V2 is the normal SC trim. You could get a Si impeller upgrade for that. Also the 928M impeller fit that model as well.
V1 and V2 use the engines oil system.
V3s are internally lubricated. Older models came with the regular impeller, but could be upgraded to Si impeller. Moot point now, as all new ones come with an update SCi impeller.
Finally there's the YSI. its huge, makes huge HP, and would need some body work on the car to make it fit. No one has put it on a G/Z yet. Pulley'd down, it would made deep into 600s maybe more.
As for power, its all over the place depending on pulleys and cars. Everyone says that the 928M impeller is so much better, but there hasnt been one car making more power than similarly setup stock impellers. That maybe due to the cars they were installed on, but nonetheless, there's no max hp data.
In basic terms they lines would fall like this (assuming same pulley)
V2 SC ~ V3 SC < V2 SI ~V3 Si < V3 SCi < V1 T trim < Ysi

I think the real strength of the 928 impeller isn't necessarily that it flows that much more at a certain rpm (although it does to a certain degree) than the Sc, SI, or T trim, but to me it's more to the fact that you can spin the blower up to 60k rpm without any worries of damaging the blower...the T trim and Si trim V1 have a max rpm rating of 55k rpm while the Sc trim V2 has a max rating of 53k rpm, so just by the fact that you can spin the blower more with the 928 impeller you can generate more cfm and pulley down more that way without any fear of impeller damage...
There are dyno's in this forum showing the 928 impeller gives a decent amount more power just by swamping it out without any other change. 350z006 got 570whp out of his 928 impeller. Granted it's on a dynapack, but how much lower could a dynojet read? 100whp less? It would still be higher than just about any SC trim I've seen.

Update to the TTrim update-
I got lucky and found a brand new OEM engine. So the dipstick being blown out of the crank issue should be gone. That motor, although damage and cost me 400 bucks, put down 410RWHP and 326TQ, the same dyno with an APS twin turbo put down 399 and 375. Custom TT kit put down 403rwhp and 330TQ. That motor also had a stair case dyno chart, not like typical dynos of a nice linear curve going up through the RPM band. So it is safe to say the motor had serious issues. Since I had no boost gauge we couldnt tell too much. I am anti gauges in my car. lol
So even with a jacked up motor the the T Trim (on my REVUP with the 2.87 pulley, headers, test pipes and full true dual 2.5 exhaust) is out performing twin turbos on stock blocks anyways.
This new motor is just waiting on the Boost Gauge to get in (today) so they all expect big numbers from the zero mile hand-built Japanese engine. Also my last engine was not grounded, yet didnt burn up my coil packs...lol
I think the dyno is thursday October 21st-ish

hey guys,
i just ordered a v3 sci tuner kit which i will install myself this winter on my european 2003 track..
these parts are on my to buy list:
dw 600cc injectors
walbro 255
aem ecu (a friend of mine is aem certified tuner/mapper)
oil temp, oil press, water temp & boost gauges
afr wideband gauge (any recommendations?)
is there any essential/important stuff that i'm overlooking? maybe fuel related parts?
things i might need (but not for certain) like cooling mods will come later if needed as i'm not sure i will need those in the moderate dutch climate and with my driving style.. i don't track and i don't do high speed runs.
i will start with the stock pulley and maybe upgrade to the 3.12 pulley at a later stage. i want to take things one step at a time. i don't see myself running the 2.87 pulley on the stock block.
i do have plans to go build somewhere in the future hence the 600cc injectors and aem ecu but like i said before i'm taking things step by step and right now i'm focussing on the essentials for the stock pulley.
thnx.

I also bought a Vortech, but I would go Turbo if I knew that I was going to build the engine later on.. 4-500WHP is the limits of the Vortech anyways..
the difference is the Torque..
I would also say go with 3.12 pulley to begin with.. but your friend as a Tuner maybe makes it a lot cheaper for you.. so no problem there maybe..

hehe i knew i shouldn't have said anything about building later on (:
and yeah i get a discount from my pal so getting multiple tunes is not really an issue and i just ordered some books on the subject because i want to learn it myself.

The 3.12 stock makes 8psi if I am not mistaken and with the 03 it makes 9psi.
again not sure, but I think its the other way around?

Hey all quick question; is there an appropriate, easily obtainable substitute oil for the V3 blower? We don't have a lot of outlets that sell Vortech in Oz and it would be easier if I could use engine or gear oil instead of having to track down Vortech V3 Oil.

I'm thinking of doing the follow build:
stage 1: V3 SCi w/ only modfication a 3.12 pulley on a stock engine.
stage 2: (~9 months later) upgrade impeller (928), fuel pump, injectors, fluel return lines, 2.87 pulley, and probably short block.
I'm choosing above since jumping straight to stage 2 will prob cost at least twice as stage 1. I'll have the cash in 9 months for the stage 2, but not the patience to wait, hence why i'm considering above.
question is w/ my above stage 1, stock V3 vortech w/ 3.12 pulley (custom tune), you guys think the fuel system will suffice?

i've heard quite a few in person. v1's are common on v8 applicatinos. They aren't that much louder. Unless you're standing outside of the car while it's idling you can't hear the gears. When you're driving you hear exhaust or the intake bypass valve blowing air and when you're wot you don't hear any of that.
