Alberto's got it right - compare the torque curves - don't look at peak #s. str8dum1's 405 trq at 17 psi on the same engine where turbos got him 550 at 17 psi weren't at the same rpm and temperature - those would be the primary differences affecting power output for the same boost level on the same engine (relating to VE and air density respectively).

Above numbers are very rough ideas, my car can definitely put different numbers... I'm just using what I could gather from other posts.

I know Turbo can provide both, but I'm focusing on SC at the moment.
In this specific case I would you go for the Vortech. If you can still afford to spend the addl $3k then get cams (JWT 272's????....) & fuel management system a-la CJM stage2 + dbl pumps. Just a suggestion

if ur just looking at superchargers then go with the vortech..much more room to grow over other kits and its a good quality kit, easy to just get the complete kit and run the 3.12 pulley on stock block and stock internals with a re-tune of the ss box..very simple setup that works well for some decent power...and ur numbers are very off..i made 420whp/355ft. lbs. on the 3.12 pulley at 9.5 psi on a dynojet...u cant go by numbers that u have seen...

Just get a temporary address or a buddy in AZ or NV, and get a licence plate in that state. Cops won't be able to bother you when your car is registered in that state.

if torque is such the thing, then why dont more people use nitrous set ups?

Seriously, just curious.. I dont ever see spending 20k more on a car that was on 28 k new.. so turbos will always be out of the question for me.. but 2500 bucks on a good progessive ute'd and window switched nitrous set up seems pretty do able.. and i hear its almost "ALL torque".

After 6 months of steady N20 use, you will realize if you had saved for 6 months you could have been close to going FI and had it all the time.

Most all people with nitrous that USE it, always regret doing it and not waiting and saving for FI.

that's why you get huge turbos and 250shot it out of the hole and have the turbos carry you the rest of the way. 6-700ft-lbs at 3000 rpms while still making 1000whp at the big end.

best of both worlds.

Thats all fantasy talk, most guys with big numbers cant even drive.

The proof is in the drag forum!

LOL, for sure. Bri's recent 10.9x pass really puts the trap to the ET in perspective.

To some extent less HP cars are easier to drive. I need to find a way to remove 400+lbs from my G to match Bri's curb weight. If the G35s were 3250lbs, there'd be alot more with faster times.

Well for some of us there is a problem of getting more than 1 pass in before getting the boot

hmm, interesting. i wonder how that works if your license is cali.
so if you get pulled over w/ cali license and NV plate, they'll let you go? i thought they forced you to get registered at the state you were at (or maybe i'm thinking about insurance wanting you to be registered in the state you live)
food for thought, love to hear more about this

i'm surprised your same track lets you keep coming back. i can run whatever i want at our 1/8th mile test and tunes. Thats perfect cuz I can practice my launch all I want. I didnt take my vortech to the 1/4 til I could cut 1.8s pretty consistently, then I broke on my 2nd pass because they actually prepped the track...

dont you have a 1/8th mile TnT night? That will give you seat time. mid 130s is moving, mid 10s should be there. What rpm are you 2 stepping at?

bump...

Everyone is saying torque, and I agree, it feels much better.. I have been driving many Diesel cars with high trq numbers.. and it "feels" very fast.. but in the end of the day.. the hp cars win?

am I wrong guys?

Higher HP does tend to win because low end torque is useless when you are constantly at high rpms. BUT, the initial pull when you go WOT is what makes it feel faster. Also coming off the line.

torque is good for a low end grunt when driving around, but when u are gonna race someone or run the quarter or something along those lines u are always up in the rpm's and that is where your horsepower is...Running the quarter in the z i was never under 4-5k rpm so torque was really doing nothing for me...also if driven properly a car with a lack of torque and good horsepower can just be downshifted and be up in the rpm's where the horsepower is at...

and torque is not entirely going to get you off the line faster..torque will cause more wheelspin for one, but if u have sticky tires and are launching at 5k and never under that then like i said before the torque is not really doing anything for u at that point..

came to revisit this threat. just ordered vortech, will run w/ 3.33 for a bit to get used to it, and will upgrade the pulley and retune the ss box and go from there! thanks all
