Ive been looking into getting a supercharger for my Z but theres one problem stopping me, is about the belt slipping because my cousin have a rsx supercharger and sometime his belt slip. Someone at told me that the vortech supercharger belt slips a lot so I was just wondering if its true? Ive been searching it but havent come up with a conclusion so I want to hear some opinion from you guys. Thanks please let me know

 

just get a gtm pully mod and prob solved

 

do a lil searchin on vortech threads but if u have a stock block and plan on runnin less that 10psi u will have nothin to worry about. please dont go procharger...they have the belt problems ....

 

ive ran the 3.12 pulley for about 10k miles now and no belt slip and i dont have the extra gtm pulley mod or anything..proper belt and properly tightened and there is no problems...vortech is the way to go if ur going supercharged

 

How much are you pushing on it and how often do you drive your z? Please let me know thanks

 

During the summer its my daily driver..I drive it everyday to and from work and all over, and track it once in a while too..I see 10psi with my setup and no slip ever to date...U really have nothing to worry about...vortech has a new belt layout that is much better than the older style...

 

GTM mod, just under 12psi and no slip at all.

 

Thanks a lot guys you guys are very helpful and I wonder how much would i make to the wheels with strup headers MREV2 with spacer HKS Exhaust Helix Test Pipe ?

 

^every car is different...

thanks everyone for the tip on GTM's pulley mod.

 

is that the one? http://www.gtmotorsports.com/product...cat=258&page=2

 

Yeah I am aware of that but what I'm talking about is what would I be expecting? I'm not asking for an exact number

 

between 325 and 375 hp

 

guys, is that the one i need to prevent slippage?

thnx

u are not gonna need to gtm pulley mod..u would only need it if u were going for big boost...there are guys here making 15 lbs. plus and not having slipping issues..for just 7,8,9,10 psi u are not gonna need it...give me ur money if u wanna throw it away

 

what pulley do u plan to run? because u do not need it for the stock 3.33 pulley for sure or the 3.12 pulley and really not even for the 2.87 just the proper belt and tension...are u stock block or what?

 

just trying to be safe bro...

i'm gonna run 2.87 on a stock block.

 

I still say u wont need it with the correct belt on, but at least u are saying u are gonna run that pulley and ur not just looking to run the 3.33 or somethin and think u need the pulley mod..Honestly i would run the kit with the 2.87 pulley and see what you got and if you get any slip for some reason then do the pulley mod, just get the right belt size on and tighten it down right...Its not gonna hurt anything to get it but its just not something u need with the given pulley size

 

i know what you mean.. but getting the kit altogether saves me time and money.. those things aren't available next to me, and the earliest they can get shipped to me would be 7 days minimum. and on top of that, that's the only car i've got. so if it slips, that means the car will be parked for a while waiting for the part to reach, and i'll end up renting a car to go back and forth to work..

uhhh.. i totally agree with you on it being a waste of money if not needed, but i'm just trying to play as safe as possible and try to get away without having loads of issues.

thnx tho
