i have been seaching for a long time now and cant find any reason to buy a supercharger. vortech says 411hp but it still runs low 13s with bad trap times. you can do these time in a non FI. so $6K later you did nothing to your car, i just dont get it why do you but it? i really want to go FI but i cant afford a new motor from a turbo setup. i keep looking at the aps ST kit, but iv read if your motor is abused it wont last long. i do maintain it well but i admit i beat the crap out of it every day.

so basicly why do you buy superchargers if it doesnt really make it any faster?

 

a supercharger is a whole different deal from a turbo setup. A supercharger would never really be good on a track unless it was upgraded. A supercharger provides power through out the whole powerband. While a turbo give you a big boost of power and torque. A supercharger would definitely be fun on a highway or anywhere you already have your rpms and speed built up.

Choose which route you want to go by what you plan on doing with your car.

 

411hp is not whp but to the crank at 8psi so u aren't really gaining much (around 330-350 hp to the wheel). If u upgrade to smaller pulleys like the 2.87, u can get the # in the 400 whp range. So how can u say it doesn't really make it any faster?

 

because unless you are a pro racer you are lucky to get 13.0@106 mph on slicks? so where is the added power? and as for what i would like to do with the car, i do like to play alot more then racing but i hate loosing to every thing all ready as it is now. i do have a nother car with a big turbo and i drag race with so im not too concerend with going fast but id still like it to be faster. if i would go with the hks supercharger is it reliable enough to beat on it every day with out motor damage? im not putting down the supercharger i LOVE the way it sounds and would like to have one but dont see where the money spent is.

 

who told you that it doesn't make it any faster?
its fast but not as fast as a turbo setup...
unless its a stillen s/c u won't feel the torque down the curve... maybe that's why u might feel like the car isn't really fast.

 

How can you say it doesn't add any power? From what you are saying it will add over 100hp. I think you would notice that. The reason people do superchargers on Z's is because the torque delivery is less than a turbo and on our stock rods it adds peace of mind. Sure it won't be as fun as a turbo but it still gonna be fast and with a 2.87 pulley and supporting mods you can easily be over 400whp. Trust me, you would notice that and be faster than 13.0 @ 106

 

You should not go FI then. If you plan on beating on the car things will brake not matter what you are using, supercharger or turbo. Don't forget, tuning has more to do with it than type of FI. I went out and got a Haltech for this reason, it cost me more than my entire turbo build.

 

You supercharge a Z because of this..... CARB emissions

 

i ran 13.1 @107 with my stillen supercharger at 7lbs and i ran 14.5 without it so i guess it did something.

 

Plus only 2 people have really gone all out drag racing and those 2 are shop cars at this point. I'm sure this season will see some sick times from the VQ crowd. Lots of people have stepped up a ton in the last few (winter) months.

I have 400whp with my HKS SC and I would say its very noticable from stock...

I am going to twins though since I would like more power, I was very happy with my SC though.

 

So you think Vortechs are slow huh? Check out this thread.

https://my350z.com/forum/drag/405988...e-vortech.html

 

im guessing the OP feels that spending $3-4 should get him in the 11-12s...

 

never said it was slow was just looking for some one to tell me it was worth getting. and you are on stock block and feel safe saying that ur motor is fine and not scared it will blow? and when buying a vortech kit do they all come with same blower or do you have to buy a new one after you allready bought the kit? and those are times worth the money if my car did that i would put out the money no problem.

 

99.5% of people cannot get anywhere near sub 11.8's with a vortech. i'd so turbo if i was you. You'll buy a blower and be pissed its not fast. With linear power and torque, it doesnt put you in the back of your seat like a turbo.

so i am telling you its not worth it based on your original post.

 

im not worried about other parts breaking just rods pistons i have tuned my 98 volvo for over 370whp on stock block tuning my self on street runing 12.6@112mph so i am pretty good with tuning just not sure about what the z can handle. no matter how much searching i do i just cant seem to find that answer "can the car handle it abuse".

 

With my Vortech and other mods I've added nearly 200hp to the rear wheels since my first dyno when I was mostly stock. I'd guess most of us who go with a supercharger do so for many reasons, like cost, no need to build the motor, it's easy to install yourself exc.

It's may not run with the turbo guys, but it's still a lot of fun, the blower whine gets peoples attention. It sounds way cool and has plenty of power for a street car.

 

thank you str8 that was the kinda answer i was looking for

i had a 2008 scion tc befor i got the z and i put the vortech kit on that (trd) and it was the worst $3k i have every spent. had it supercharged for about 2k miles befor i got the z, that is what makes me question it so much. and also on the tc i put a 9psi pully on it and it would go to 9 about 5.8k and drop right to about 3 psi does this happen on the z or does it hold to redline?

 

simple answer...the rods can handle about 400rwhp and 400rwtq SAFELY.

yes some have pushed harder but not for long before they built.

Everything else holds up very well. Not many people just go in and replace rods, they also do pistons, rings, bearings, connecting hardware, etc....why leave an unknown weak link when you are already in there?

Heads and cams flow very well....some of us making north of 800bhp with them...big reason to do cams will be to get more revs (and its a little easier on the motor).

thank you another very good answer i was looking for about 370whp for daily driving, and tuning is 1st thing on the list been there done that with my volvo on bad tuning.

was allso woundering if a 370whp+ supercharger is alot more noticalbe then a 330+whp. and i see the vortech mph are better then the hks 1/4 mile wise, why is that? dirver error or the vortech just better? i wanted to go hks cause id like to work the fcon it comes with.

and to dhwang80 money dont really matter i perfer fun over money, but i cant put out the 10k+ on a twin turbo kit just for my volvo that maybe has 4k of upgrades in it to blow it away
