NEED CRANK PULLEY!!! for s/c

[SinCity328]

Does anyone know or have a larger diameter crank pulley for a e36 ??? I built my supercharger kit from scratch using a powerdyne bd-11a unit and with the stock tiny 5" crank pulley i am only getting 6 psi, i need a 6" or larger crank pulley, any suggestions would be great!!!

Also does anyone have a used LSD for sale??? This may sound stupid but does a e30 lsd bolt up???

Thanks,
Maurice

Hey Guys... A good guy (ScCab) I sold a crank pulley to, just emailed me, and said you guys were looking for 6" crank pulleys. I have them available...one can ship Monday and another on Th or F. The price is $350 shipped in the 48 and includes a free spacer for the sc pulley. The pulleys are custom made from 6061 and can be made ANY diameter that you wish to mess with!!!

You can pay by paypal to buldogge@sbcglobal.net or snail mail to:

why not just get a smaller pulley made for the SC and not mess with everything else attatched to the crank pulley?

& i thought the gearing in e36 trannies was different- 1:1 5th, no? dunno if you'd wanna run that with a 3.73 on the street...

Is belt slippage. Larger pulleys on both ends help limit belt slippage AND promote better belt wrap. using the larger crank pulley allows you to still adjust boost but then you generally need a larger sc pulley to step down a bit...afain decreasing belt slippage issues. As far as 3.73...it's a lot of fun...but I would run the 6-speed (which I have) for the street. BTW, I have seince switched to a 3.46 with the supercharger set-up.

question im not a pro but my car is gna get 6-8 psi with the current pulley i want to set it up for 10psi what pulley do i need and what size do i need to reach this psi. my current pulley is the stock one from dinan.

also with that pulley you were mentioning that you can change the diameter, does that mean you can make it bigger and bigger to get to the psi that i want to get?

will it work in my dinan s/c kit?
anything else to make it work?

[buldogge]

You will use the 6" crank pulley along with a 3.33 sc pulley most likely...this will yield about 9.5-10psi...If you end up needing a bit more you can go to a 3.2x sc pulley or if you end up a little over you can go to a 3.43 sc pulley (you probably already have this size...so you will probably end up at 3.33).

I explained the misunderstanding about there being no "adjustable size" pulley in my pm.

So...You need to add the 6" crank pullet I sell...=+3psi!

Paypal away...

how your fast haha just wrote on this thread do you have aim so we can talk more my aim is bgynite, im realy intreasted could buy today. mine is the stock set up so do i need to get a 3.33 pulley too. or what does my kit have now ist just the stock dinan kit.

[@bgynite@]

my paypall is already to go i need to know besides the belt what else might i need will it just bolt on no extra things needed?

do i need that 3.33 pulley you were talking about?

how much is shipping?

is it $350 straight up or does the 350 include shipping?

my shipping adress will be on the paypall note section.

[buldogge]

I include the spacer that MIGHT be needed...

You have either a 3.33 or 3.43 sc pulley depending on year of dinan manufacture.

Supercharger pulleys can be found for reasonable money at:

Actually, he's got a Powerdyne, so only Jeebus knows for sure what size blower pulley he has.

[SinCity328]

Just wanted to say thanks to -buldogge- he made me a BADASS 6.5 " pulley i went from 6psi to 12+ on my powerdyne bd-11a!

He even got it shipped out in 2 days!

Thanks,
Maurice
