Im really thinking about buying a V2 S/C for my car but I have a few questions

1) With having a Variable intake will I still be able to have a raised rev limiter for the car or no ??

2) Is the V2 kit a reliable kit ?? compaired to Turbo setup

3) Is a V1 blower a better setup in the end than a V2 setup ??

1) VI and raised rev limit are made for each other. The combination of a centrifugal SC, VI and raised rev limit results in fabulous high end performance. Low-midrange power is lackluster compared to what you can get with a turbo setup, but far superior to NA. Driveability is superb with a supercharger kit, with instantaneous throttle response.

2) My experience with the Stillen V1 kit is that it is super-reliable. I have had absolutely no problems with it in the past year/20k miles since installing it. I have no experience with turbo kits, so I can't compare. The reliability issues with the V2 kit are related to the plastic idler pulley, and at least one person has had a blower bracket break. The V2 kit comes with an aluminum bracket, V1 came with a steel bracket.

3) The V2 blower is quieter and develops about 1 psi more pressure at a given belt speed, due to a slightly higher internal gear ratio. The V2 kit had certain reliability issues that the V1 kit did not have (mentioned above).

 

So you can have a JWT-ECU with raised Rev limiter and not spin the Blower out ?? maybe I should wait and have the ECU programed with injectors rev limiter

What about the hole mounting braket not as strong ?? is that a big concern..

Im really considering buying a S/C cause I want that extra little bit...I just dont want to make the wrong decision when maybe I should get a V1...I do like the sound of the V1..never heard the V2

It is possible to overspin the blower with a small enough pulley. If you have a 7200 rpm rev limit, a 3" pulley on a V1 will spin the blower at just over 51 krpm. That is more than what Vortech recommends, but only by about 1 krpm. There's a bit of headroom, according to what Vortech told Mardigrasmax.

If you have the rev limit raised, it's cheaper in the long run to have the ecu programmed for 370 cc/min injectors and do it all at once.

 

So If I get the V2 with the stock Pulley will I need to retard timing running stock Boost 9psi ??
You have to give me a break cause I am really new all this boosted stuff and I want to do it right
Now all I have to do is decide If Im going to buy this V2 or not

Anyone ever have a Blower rebuilt by Vortec ?? How did it come out ??

-matt

 

Boost with the stock pulley is 7 psi for the V2, but to answer your question, no you don't need to worry about timing until you start groping around above about 10 psi.

Iansw had his V1 rebuilt and upgraded to a V2, he's really happy with how it turned out, I believe. He regained 3-4 psi of boost he was losing through leakage.

 

You need to get one step colder platinum plugs. My stock plugs looked ok after I took them out but the one steps help reduce engine knock. I don't know if you mentioned your transmission or not but if you have an autotragic you need a tranny cooler and the VB mod for the tranny. If you've a 5 speed you just need the tranny cooler.

Rebuilds by Vortech are good. Just annoyingly slow to get back.

I've seen 9 psi boost with the 3.25" pulley and I need to do a dyno again.

If you want to break the 300 hp barrier you should talk to Iansw. He's the man!

 

From what I have read on here, it seems that someone using a 2.87 pulley should be using 2 steps colder plugs. I guess it depends on the gap used? I may be getting my facts out of wack.

It appears this is not the case, people using the 2.87 are using 1 step colder and appears to work fine.

Why cannot one simply just use copper instead of platinum?

 

With the stock 3.60 pulley you can get by with the stock plugs but its best to go with one step colder. Frome what I've read here it all depends on what pulley you have that determines whether to go 1 or 2 step colder.
Copper is fine as long as you're aware that you have to replace them more frequently.

 

I am using the one step laser ngk platinums and its working pretty good...no compaints.
matty!!...get that v2 set up + VI+ 370cc+ JWT ECU= a piece of mind. believe me it is awesome to harness such power. take advantage of our 95-96 year for the raised limiter. and yeah Iansw is the ishnit..take his advise as he is one of our maxima tech gurus along with some of these guys here...they will show u the way

 

Wow. I'm touched.

Here is my setup:

V1 SC Bracket
V2 Polished Blower
2.87" Pulley
Copper NGK BKRG6E-11 (ONE step colder) plugs.
JWT ECU with raised limiter
300zx Injectors
A32 MAF (soon to change)
MEVI (set at 5200 because I'm 5spd)
5spd Conversion

No complaints or issues except that I am running out of airflow on the A32 MAF at the moment. Need to get a Z32 MAF installed and the EEPROM reprogrammed on the JWT.

 

I htink JWT NA Programs do it as well.

But yes, the Boosted program is VERY different (retards timing)

In addition, I got my V2 from Vortech within 7 days.

 

iansw,
you got a beautiful car

 

Thanks!

As with pretty much everyone's car on this board, it's a "work in progress".

 

How much does the JWT Boosted program cost with rev limit raised and 370cc Injectors ??

So I will need one step colder plugs, and a tranny cooler ??

-matt

 

About $700 I think - I bought mine used from brodaiga.

and the answer to the second part is yes.

 

Tranny cooler...where do I get that ?? how much ??

Lucky me gets the see this car in person a lot...and I tell you it really shows Ian's pride and joy.

My JWT ECU is at JWT right now.

Ben told me not to go over 7000 RPM limit.

THe ECU currently has a 7200rpm limit running stock inj NA program.
any feedback on this limiter?

I am having it programmed for z32 maf, 370 inj, and boost program. It cost me like $100 per trip to JWT.

I currently have 6 factory sealed brand new 370 injectors. I am really tempted to trade these up for 555s, any opinions on this? I could have jwt then use the 555 program. Would I be able to run NA on 555s?

My current project is to get my 5th gen v2 kit to work with my 4th gen max and a z32 maf. Maybe I will start a new thread for advice,etc on this. Jay25 has been very awesome with his knowledge on this. Thanks man!

 

That's where I bought mine.

 

Hell, it's your pride and joy too man - you work on it as much as I do.

I just get to make payments on it.

 

how does it install....??

-matt

 

Uses an install kit (that comes with it).

You run the tranny lines that exist already to the in/out port on the cooler.

Pretty simple - uses a zip-tie type of thing to stick it to the front of the radiator.

Heh - I still have mine installed on my car - It's not hooked up to anything since I went 5spd. Need to remove that one of these days.

 

NO...I have a 5spd ????

Im confused now

You don't use a tranny cooler with a 5spd.
(Well, in theory you could, but why would you?)

Bad BlackCat!

 

Why are you getting 555's? what kind of setup are you going to have, and at what hp levels? what would you sell your 370s for?

 

I guess I do not need 555s currently, I just thought I might plan for the future.

I would not sell them, I would trade towards 555 hehe, but that won't happen.

 

ok I stand corrected!

 

Now with the V2, I have been hearing horror stories about belts sredding to crap...the guy I am buying the blower from 190hpkilla has a metal lexus pulley i guess in place of the stock plastic one...I am very conserned with shredding pulleys becuase I am..

Do I have to worry ??

-matt

 

I cant' speak to that. I have a V1 bracket and have never even jumped a rib much less shredded a belt.

 

can anyone ??

-matt

 

It's all a matter of proper installation. The installer has to be sure all the pulleys are lined up nicely. With a V1 that was never a problem, the bracket was made so that everything was lined up perfectly. With the V2 kit, some people have had to use washers to adjust alignment to keep from shredding belts.

 

I've shreaded a few belts between a combo of inproper tension and alignment. For a while its a trial-and-error kind of thing.

Its not really that big of a deal. The stock belt can go on without changing anything, so you can drive the car. Changing the belt takes 2 hours tops once you've gotten the routine done.

 

I've had my V2 since Oct 2000. Up to now I've had 2 incidents of belt shredding. First one was my fault because I placed the washers in the wrong places. Second one was when I stomped on the gas when the engine wasn't warmed up enough. No biggie as Ejj has said. Just annoying and inconvenient when it happens.

As for pulleys they don't shred. They just wear down. That's why there's a Lexus pulley in that kit you're looking at.

 

matty
be very careful when installin the S/C, u need to allign the belt the best u can. u hear all the horror stories about belt shreddin is cuz the alignment wasn't right. i aligned it propperly after i shredded mine due to installation flaws. be aware of that and u should be fine. fogettaboutit

 

I might have a V1 kit for sale soon.. :-/

 

Any reason why?

 

I was going to get a new car... but now i think im back to modding the max.
