Tired of the beating, I want to charge my ride!

So in reading the post, obviously the vortech offers more hp but it sounds like the stillen is more reliable. Neither are cheap and as you guys stated they MUST be installed correctly which is a given. So the 6k $ question is vortech vs. Stillen? I still want the reliability, but on the other hand 500hp sounds allot better than the stillen option. Are there or have there been any issues with the drivetrain holding up under the added hp? Or does or will it also need attention as well? On another note, the transgo kit correct me if I'm wrong really does nothing but change the shift points?
 
Interesting thread, except for the bantering. Some people don't know when to give it a break. I think it would be awesome to have a SC'ed FX.

I agree. Most cars dyno low, except for a few exceptions that are under-rated and dyno at the wheels what the manufactor lists as crank horsepower. Example the Chevy Cobalt SS. The true test happens on the track.
 
Just for your information...Stillen occasionally has some sale going on and I have seem the SC selling at 4700 around black friday . I haven't looked at the Vortech ones but believe it should also have some discount if buying at the right place right time.
 
Hey if you can get a Nissan juke with a GT-r engine in it why not an FX right. You can make any car fast regardless of size or weight.

I saw that! Funny thing is that Juke costs about 90K and do not have HID headlights. It basically a Juke with a GT-R engine, no additional luxuries compared to the average Juke. Probably fast as crap though. However, for that kind of money I would just buy the GT-R. Now, I would consider buy it for about 60K however just to see the look on some Jeep SRT-8 drive's face as I dust him at the local track.:rotfl:

Its a modified version of the Stillen kit thats more reliable. You have to ditch the 7th injector, upgrade the six you already have (mine are 440cc), and get a custom dyno tune.

Also, you are wrong about the Transgo kit. It actually doesn't change the shift points, but rather the spring and line pressures which make for faster and firmer shifts. The kit itself is a bunch of valves and springs. No software.

I put down 250 on a Mustang pre MD exhaust stuff, so that's probably 260ish now.

Also, everyone knows it's always important to be the first to the red light. :tongue:

Chuck...How do you like your new ride with all that 350 whp? Could you give us some more details about the joy?

I wish. The supercharger is collecting dust on my workbench until the built motor is finished. I drove it a few times in the summer though and it was awesome. Its not unruly or anything, just gathers speed like a freight train. That was in rwd mode, on dry pavement, with big heavy 22" wheels on big heavy 285 tires. I drove it once in the rain and scared the hell out of myself. After that I immediately parked it for the sc swap onto my awd FX.

Just another data point. I had 425whp at the rear wheels using a turbo setup using 12 pounds of boost. Any more than that and the transmission would start to slip. We went as high as 16psi with slipping. My transmission used the Level 10 rebuild, transgo shift kit, oil cooler and Torque Converter was modified for a higher stall speed. This limit at the transmission translates to about 550whp at the crank. We used torque management features in the Haltech ECU to safe the driveline.

I don't believe there is any data to support the Stillen being more reliable than the Vortech. Neither one of them have very many examples from which to take data.

Using the centrifugal type Vortec Supercharger, boost is delivered more "gently" at lower RPMs and should allow a higher ultimate whp to be reached without slipping the clutch plates in the auto trans. The downside is low-end grunt, which hurts you in a big heavy car like the FX. You will probably not beat your friends off the line but you should reel them in and pass with a Vortech on tap. Tuning is the most important part of the installation - UpRev Osiris or an aftermarket ECU is just as important as the parts you purchase. The Vortech is just inherently safer to the driveline as compared to a Roots style but both still require tuning!

the different between them, just like a 350Z and a Pathfinder.
go get a RWD, if you really like the red light racing.

Say whaaaaaaaat? I have both awd and rwd in my driveway right now. If your 07 is really that much slower then it's got problems.
 
umh, if you ever owned a Pathfinder or QX4, you know what I'm talking about.
Pathfinder or QX4 not a slow vehicle, just totally different driving experience.

or maybe I forgot the driving feel of RWD FX35, I had the FX35 RWD while I had the I-35 at the same time back then.
Now I have the FX35 AWD, and the 335i

again, Fx is the wrong car for redlight race, go get the 300zxTT,, I smoked a 911 with that Fairllady.

The AWD FX is the exact same as RWD. Slightly less power to the wheels because of drivetrain losses and it has a sway bar. Suspension is the same so I'm not sure how it would feel like a QX4. I doubt there would be much difference felt in a straight line. I do agree that the FX is the wrong car to make fast unless you want to spend crazy money.

Between the Vortech and Stillen, go Vortech. Stillen's blower is too small for the VQ so there's only so much you can do. It maxes out at 350whp and takes a lot of additional mods to keep it reliable at that level. Check out the 350Z boards or even G boards, the Stillen just happened to be the first SC option. It's widely considered the worst SC option right now especially at the price they charge. However, if you look, they have terrible resale so you can pick one up for ~$2K if you're lucky.

Vortech will make more power, but it's a different feel. Full boost comes at redline by design so the powerband is more linear. The car won't "feel" as fast because on the low end, not much boost is made. On a previous car, I had a Vortech and it made decent power. But when I swapped to a custom turbo, the car felt so much faster (and was) even though peak power levels were similar. Different between hitting full boost at 3500rpm vs. redline. The Vortech will be easier on the motor than the Stillen, less heat and boost is progressive. If you're going stoplight racing, the Stillen would probably be quicker. If you were making highway runs, the Vortech wins.

Neither one is a terrible option. I considered the Vortech, but have decided to hold off on it since I got a 335. Can't justify dropping $6K+ (Vortech, injectors, management, etc.) to maybe run high 13's when my other car can run low 12's w/ just a piggyback. Maybe I'm getting older, but taking a car and making it something it was never meant to be doesn't appeal to me as much anymore.
