VQ35HR Stillen S/C & VQ37VHR Stillen S/C setups

Lucas08'Nismo · 07-29-2015, 01:30 PM

Alright folks, I have a 2008 Nismo 350Z with the VQ35HR Stillen supercharger kit on my car. I am in search of information because My350Z forum does not have a thread on this supercharger.

My question is: Are the VQ35VHR and the VQ35HR serpentine pulley setup the same? If so, is anyone running a vortech 2.87" pulley on their S/C and did you have to change the length of the belt to compensate the .050" between the OEM S/C drive pulley or did the tensioner make up for the difference?

Belt part numbers would help me out a lot if anyone has one.

Any help is appreciated. I have leaned on this group for almost my entire build so far. Thank you very much everyone!

Not sure about the serp sizing.

But im running a 2.70" on my charger and using the same belt setup as it came from stillen

You are using a 2.70 but I think you said you have a 2.70 on jackshaft also. So your ratio is 1:1. The same as it was before changing your sc pulley. You could put the 3.2 ones back on and make rhe same boost.

I am trying to figure out what similarities the two VQ's have with this kit. I do not have anywhere else to go for information and i do not know how reliable the VHR info is to my HR. If i can put the 2.87" pulley on and still keep the same belt, perfect.

Also, does anyone know of alternate serpentine belt configurations? I know the DE's have many setups to reduce belt slippage by adding idler pulleys into different spots and deleting other pulleys.

Any part numbers for this kit would also help, like mentioned above.

Again, thank you for the help.
