What super charger do you run and did you buy a kit or make it yourself?

[Talkwrench]

The kit is basically the CRS one using the SC14 Aisin off the Toyota supra. I was going to make up the mounts myself however was lucky enough to find someone selling them so saved me a heap of time and trouble. The kit from CRS is now overpriced and does not even include the supercharger anymore, others now on Ebay.

hey mate nice lokking car... how dose the pro-comp ignition go??? i was thinkg of putting one in my car

cheers

To date I haven't had a problem with it, tis a little noisy though. Putting the HEI dissy on a red motor is a big boost, adding the MSD is only slightly better if anything. Take the trouble to get your dissy graphed you wont look back.

Where are you running your PCV to? I was thinking of plugging mine into the Holley inlet before the blower!

Thanks

Scott I dont run a PCV. if you have a look the breather comes out of the rocker cover via the catch can and then out underneath the car, just like the old "walking stick". I had such a problem with the oil passing past the PCV into the motor after fitting roller rockers [pre supercharger] I just we back to the old fashion way.. works fine.

did you have to lower the compression at all?

Talkwrench,

I have a few questions on BOV's and pulleys. I saw on Oldholden you said you are running a BOV. I have a BOV here, but it has me stuffed how to fit it. Any tips?

I am also looking into running the blower with the clutched pulley. I have pictures of it in my shed on OH. I may never use the clutch but figure the 7 rib pulley will be better than the V belt. Have you found a new drive belt set up yet?

Thanks mate
