I just saw this...that blower will not be happy until it's making a ton of boost/power. lol Ask me how I know! lol
In all seriousness, I would HIGHLY recommend putting a crank support on sooner than later. There is no slippage on a cog set-up and the tension is greater than serpentine deal (In my experience with mine and my buddy's BBC blow-thru serpentine set-up). IMO, the issue isn't really the amount of boost made, it's how much "pedaling" happens on a pass or if you're going to be driving it on the street. I replaced two crank snouts before I learned my lesson and it cost me far more money than if I would've done this in the first place!
Here's the link to the crank support I have for sale. It has all of the details...If you are interested let me know. I am tired of it being in the way and moving it around my shop. lol So the price is negotiable.
If you have any questions about it, please feel free to ask or shoot me a PM with your number and I'll give you a call. Thanks!
PS. Nice looking car man!
