There is a DEFINITE difference from Stage II to III..... I could not go the strip Wednesday night b/c of rain, but tonight I am gonna race a guy who use to kik my butt and see if I can take him now! He has no idea I have more boost now........

 

I'm going to the dyno this week to do a baseline with stage 2 and then switch out to the 8.3lb pulley. I can't wait to see what it does.

 

It should have had a bracket on the bottom already. Mine did, secured by 2 mounting screws on the bottom, and one on top.

 

Me too (ie can't wait to see ....)

 

BLN350Z,

Sooo... how was your drag event with stage 3? Details if you have them bro.

thanks
Sukhi

 

It was raining at my house so I didn't go, but I am planning on going this Wednesday if I don't work again...... I'll be sure to let yall know the results.........

BLN - R U running @ No Problems Raceway or is State Capital still open? I need to make a pilgrimage to either one before my Vortech goes on. I'd like to see how my runs N/A then on the bottle.

 

State Capitol is just a piece of CRAP in my mind so NPR is where I go!

 

So what's the verdict on stage 2 vs. stage 3. Do you have the comparison #'s yet (HP/TQ/1/4mile)? I've had a stage 2 for about 3-4 months and am also thinking about upgrading to the 7 lb pulley. My only problem is I bought the warranty when the Stillen was installed and of course the warranty is voided the minute i go to Stage 3. I wanted to confirm that there will be a noticeable difference before I do.

 

is this just not enough power? Does the stillen add too much weight so that the power added isnt really a transformation?

 

bump

 

There is plenty more power with the stillen, it's just that boost is addictive. If you have a great power increase but can get more with a $100 pulley switch, why wouldn't you?

When I first bought the Z I thought it was pretty fast. A few months later I was a little dissapointed and craving more. I put the stillen stage II on and was thrilled. A few months later I was craving more. Now I have a custom 8lb pulley, and I still want more.

Maybe it's just me, maybe some of us are never satified. I think I may need an 600hp viper to be truly happy. Until then, I have a pretty damn nice car right now.

 

Yes, driving the Viper is like hitting the crack pipe, the torque is highly addictive, but after 3 months you'll probably want a juicy turbo on it.

 

Actually, I was thinking the Roe supercharger with methanol injection

 

Good thing is, if you can tune the car right, custom pulley can truly bring out the beast . However, I'd probably stop at 8-9psi w/ stock rods. I currently have same setup as AdamDC, but my car is riddled with belt issues so I cannot claim any numbers. Nevertheless, once the belts are resolved I expect about 340whp, which is when the ATS clutch comes in for another 15whp (or so) in drivetrain loss removal. Then, RT cats come back on and a slighlty smaller pulley to alleviate loss of boost with new cats. Maybe that lightweight stock-sized crank pulley I've been hearing about. Then some nice LW wheels. Ultimately, I think this kit can go 360-380whp in relative safety, and around 8-9psi of boost.

To compare to stock Z (I've forgotten how the stock feels, so forgive if I'm off a bit): Imagine if you had another 50% more on the throttle at any given RPM. Currently, at about 300whp, that is how the car feels for me. I generally cruise on the road at 35mph in 6th, at about 1300rpm and its comfortable, there is enough juice still to keep up. Try that in stock Z . Or, for that matter, in any turbo/ATI/Vortech. I can get 18-20mpg in city, while low-rev driving around (keeping car around 1500rpm). My stock got about 17mpg, and had to be driven closer to 2000rpm, even while babied. I can crawl up hil with ease (MT) in both first and second gear (my parking garage gate is uphill, this makes a real easy drive now). I can start in 2nd with relative ease (stock needs a bit of throttle). Blah, blah... my opinion is subjective, not everyone drives like that . So, take with grain of salt and listen to others as well to find the golden middle.

 

I'm am wondering how 1/4 mile times compare between cars equipped with the Stillen with the lower peak numbers but flatter torque curve and cars equipped with centrifugal superchargers like the Vortech, ATI, and HKS with higher peak numbers but not as much torque in the lower range of the power band.

Does anyone have any data, any 1/4 mile times for comparison purposes? I don't think the SPEED Magazine article is accurate as it seems like their driver didn't know how to drive the cars.

 

Best I did was 13.6 at Carlsbad CA.
It was over 90F and my intercooler wasn't working.
I spun hard through 1st & 2nd.

I wish I had the n2o hooked up then.

 

I did 12.87 with M/T Et streets, stage 3, hollow cats and running lean. Was about at 320hp with hollow cats on.

 

Sport Z magazine Spring '04 did a shootout of the ATI @7lbs, Stillen stage III, and Vortech @8lbs:

ATI- 13.62 @107.82 mph, 60 ft 2.44
Stillen-13.605@106.32 mph, 60 ft 2.33
Vortech-13.47@106.73 mph, 60 ft 2.19

My take is that there isn't enough difference among them to say one is significantly faster than the other, at least more than can be made up by a competent driver. If you correct for the same 60 ft times the quarter mile times aren't significantly different. I'd go with the one with the best driveability/reliability. They said if it weren't for having to get a new hood then "crowning it [Stillen] the outright winner would be easily possible." The other two had detonation on the dyno which they commented should "not be overlooked" and for the Vortech 8lbs the detonation they saw on the dyno "might be too much for this kit to handle safely." You can get the magazine on backorder.
