I have an 02 z24 with the auto trans and was wondering what round about horsepower number i was looking at with the gm performance parts supercharger, rksport header and highflow exhaust.

.... i put down 205 at the wheels with ice on the blower, RK headder, full 2.5" headder back exhaust and a supertubo muffler.


but people have told me that thats freakish.. idn maby the dyno was off.

Have you done anything else other than that. Right now i have a short ram intake, royal purple oil, and a 2 1/2 inch exhaust. I just saw this one guys car on here that had lots of things done to his motor and turbocharged it and it ran something like a 13.6. just wondering.

In the summer I registered 178.6 WHP with just the S/Cer & 7000 miles old GM filter with zero mods. On the next run I let it cool a little I put in a K&N and lost a pony (1.?). I have not done a new run with little mods I put on not to long ago.
Remember mine is a manual.

ied say expect 180-200 at the wheels with the GM kit...

depending on mods and the dyno ur using.

With the GM kit and no other mods you shold be in the 175ish whp range.

Good enough to get you a 14.6-14.8 @ 93-94mph

Just FYI thats a good second faster then stock and 5-6mph higher trap. And thats only with the stock pulley and no mods. With i/e/h you can see low 14s or at least close to it Im sure.

Doe they offer another replacement pulley to turn up the boost a bit, and speaking of that, will my stock bottom end handle it. I can build it stronger, but for a couple of months. Should it hold together at least that long. I also plan to put a small hit of nitrous.

^ Yes they offer different pulley sizes...www.pulleyboys.com they have the pulleys and a quickchange hub for easy installation.....



Car is for Sale!Supercharger kit is for sale!

thanks for the info

www.bluetonguemotorsports.com

also sells pulleys for our S/C....i've got their 2.7 and have the 2.6 on the way and they too have the pulley and hub....and it's a 5 rib...at the time was lookin for a smaller pulley..pulleyboys only had the GTP pulleys with the 6 rib...i dunno now tho..check it out and make your choice...either way...you'll be happy....

the bottom end will hold up....but once you start gettin smaller pulleys....the S/C will generate more heat....need a way of cooling either small shot of nitrous or water injection

I would say go with pulley boys over bluetonge... for one i found pulley boys to be much cheaper.. and they do have M45 pulleys now.. .they had my stock on to copy every thing out and sent me the first ones they made and they work fine... and from what i have seen of the bluetonge, they look like they use big bolts to hold the pulley on and every thing just looks funny on it..

I have run as low as a 2.6" pulley with and with out alcohol and the engine holds up fine.... but you wont see any power gain from the 2.7" -2.6" pulley with out water, alcohol, or some kind of cooling... its been said 100's of times now though...

youll get more power from a turbo for the same price.

12.7@110MPH with 10PSI.

^^ I don't know about same price, but usually more power @ same psi.

Comparing blower gains to turbo gains at the same psi is apples to oranges. A turbo car making 10 psi could lose to the same car on a blower running 7 psi. It just depends.

Very very true... soo much more to psi then most people understand... even engine flows diferently (like Cavalier comparied to say a civic...) actualy as a good example... My buddy has a turboed 2.4L Grand Am (same engine as us 2.4L jbodys) and he is putting out same hp numbers at the same psi as a guy here with the GM supercharger on his Cavalier...

Turbo Grand Am - 5.5psi ..... 200hp
GM s/c'ed Cavalier - 6psi ... 202hp...

HP isn't exactly universal. It's a function. And people don't often realize that.

i thought since my car is an auto, it was not a good idea to run a turbo

that dyno pull was on a 98 degree day.... ice was a nessesity.

and it was with the stock pulley.

Rolando I think you should do some more reading on here and you will have more of an understanding of turbos, superchargers, HP, auto vs 5 speed, etc..

There's absolutely nothing wrong with it. However you have to understand that you will still be limited by the extra weight of the automatic transmission and it's @!#$ty gear ratios. If you installed the exact same mods on the exact same mileage and condition motors, one with a manual and one with an auto, especially boosted, the auto would be about a second slower in all honesty. I'd make sure you run a tranny cooler as well if you intend on boosting the automatic. Boosting automatics have their advantages too! They are much easier to launch, especially if boost is almost instant. And in between gears, the engine is still under a load and boost is not lost.

You should stick around the boost forum for a little while, Rolando. You'll learn alot, and that's the most important part of boost (and modding in general). Before you buy a charger ask alot of questions, almost everyone here would be happy to answer them. And don't forget to use the search option since the GM charger has been deeply covered in this forum.




Blown.

I know how they work, i was just asking what the best combo would be and to no make mistakes. My cousin and some of his friends have turboed civics aith manuels. I just want to be able to beat them, if i can with the car ive choosen. They tell me to sell my car and of course by a honda,but i tell them no cause i want to be original cuz theres not very many modified cavaliers around and its easy to take a fast car and make it faster, but to make an automatic cavalier faster than a turbo civic, THEN YOU ACCOMPLISHED SOMETHING! thanks for all the info

... well if you want a balls out mentality,

o86 head, no balance shafts, T-4 turbo, HO intake, little bit of giggle gas to get rolling, GM T480E tranny,....... so on and so fourth, you need to ask your self what you want. and then move on from there.

i was happy with a mid to high 13 sec. cavalier Z-24.

that IS balls-out lol. If you start looking at basically turbo HO with a T4 turbo, lots of internal work (and some beefy axles) you could quite possibly break into the 12s on DR's or slicks. But say good bye to street car.
