Judson???
I suggest you listen to Mike, Lester. He's
BTDT with an 8.3-1 stock 948.
Otherwise....
Hope you have a supplier of 100+RON (today's racing) gas available at
reasonable price.
These older vane-type blowers worked but they are real heat producers in the
process.
Without the higher octane gasolines of yesteryear they were designed to run on,
or an alcohol/water delivery system to take the place of yesterday's readily
available leaded, more "manly" higher octanes (at reasonable prices) to cool
things off, you'll have the normal problems associated with this application in
terms of overheating.
Only one guy I personally know of that made it work on today's garbage octane
unleaded premiums and he had the entire blower/motor "heat treated" with
ceramics which he could easily afford to do since he worked for the company
involved in the process. He also upgraded the vane material as well.
IMHO, better off upgrading to a 1275, maybe "tuned", with an alum. head with
10.0-1CR. Hook it up to a Datsun 5 speed, select your diff. ratio depending on
your type of driving, turn the key and drive away on today's more reasonably
priced unleaded pump premiums with no overheating problems assciated with
pre-ignition/detonation.

Subject: [Spridgets] Piston source?
Hello all, in preparation of my upcoming engine build I wanted to get
the groups notes on piston suppliers.
For background, this will be a 948, I am leaning towards a
performance upgrade, with a little head porting, mild street cam,
maybe a little Judson for fun.. at present the bore is at 65mm
Thanks,
Lester
