thanks i called whipple today and was told the same thing. dont know what im gonna do now. i guess crank over drive pulley it is... ill PM you if i come up whit anything.

 

Make sure you pin the new crank when you do the pulley swap. Magnacharger makes the pinning kit.

 

iv been wanting to pin my crank for a while. good think i didnt if the only way for more boost is to change the crank !

 

You can actually re-use the pins and redrill with the jig on the new crank....if your good haha. But yeah I suggest just doing it to the new crank. And don't ever pulling it off. Lining up the pinholes again in extremely difficult. But guys say it can be done

 

Matt! Whats going on? I don't know if this is a dumb question or not, but are the cobra pulleys the same? Here's a link i found after some searching.

whi-pulley - Whipple 8 Rib Supercharger Pullies for Whippled Cobras and Mustangs - Pulleys - Mustang Performance Parts

Seems to be an 8 rib. The depth of the pulley might be different considering the differences in accessories. Worth a shot if there are no other options.

 

It will not work. The dept is different

 

i am using that exact kit on my truck. only drove about 1000 miles or so but it works great. the pump was my main concern but it works great even with some coolant in the system. i have made a few 16 psi pulls through it with no drama.

thats awesome man thanks for the info. how much coolant are u running with it ? 50/50 or less ?

i talked to a friend in town that runs CNC machines all day and he can make the pulley if i can sell them. hes going to crunch some numbers and see how much the first one with the time for programing and setup and what not will be. so i may just have some custom made when i get some prices ill let you know if your interested.

 

[QUOTE=4.8whipple;4815179]I'd be very interested in buying a couple different sizes as long as they are priced reasonably. And I know multiple people on here would buy them also. GOOD LUCK AND LET ME KNOW!!

 

Id say its less then 50/50. It doesn't freeze but a few times a year in texas
