i picked up a JRSC for B18B. it came with a double belt alternator pulley so i can run a belt straight from the blower pulley to the alternator instead of one long belt with tensioners. but i cannot find what size belts to run. if anyone has this setup let me know.

thanks

i now know that jackson racing makes the belts i need, but i hear that their belts arent the greatest, especially for more than 6psi, and i plan on putting a 10, or 12 psi pulley on it, so i would like nice belts that will handle it. so if anyone knows the part # for the belts i need in a good quality brand let me know

 

i guess jackson racing makes a belt for this application, hopefully its the right size

 

hold on so if you are running a double alternator pulley you are not gonna run neither the lower or upper tensioners?????????????please explain

 

He doesn't need a tentioner, because the alternator is his tentioner. One belt goes from roots pulley to alternator groove one. One belt goes from alternator groove two to the crank pulley.

 

k then let me ask a question

i purschased a jackson racing supercharger and it didnt come with tensioners so can i just get a double alternator pulley and not get tensioners?????

 

yes. and if you look at the newest b-series JRSC kits on supercharger.com, it looks like they come with double belt alt pulleys now

 

wow so all i need is just the double alt pulley and 2 small belts and i am set???????i have the supercharger,manifold,black bag in the back....i was gonna get the new tensioners which for bgoth is like 450$ its just shocking to me that i dont need them lol sorry i am a noob

 

if im not mistaken i think the belt from the crank to the alt. will remain the same, you just need the belt from the alt to the SC pulley

 

wow anyway i am missing a few brackets on my sc is there any real necasarry brackets i need

 

i just talked to jacksonr racing/moss performance and they told me that this is untrue and that i still need to run tensioners???????if so please dont spread information that you are not sure off.......


anyone else opinion

 

anyone

 

Yes, you still need the tensioners that are part of the B series kits.

 

thx for clearing that up also will i be able to safely tune it on s100 or will i have to go for the s300

 

If the S100 has the boost option, and your tuner is equipped to tune the S100, there is no reason not to use it.

 

Was this a real question? Of course you need the upper and lower tensioners.. How can the alt tighten both belts if SC and Crank pulleys are on opposite ends? Think about it please...
