It's been a while since I last posted. Well my 1.5 L whipple started making a rumbling noise. It is shot as far as bearings and case ,and rear bearing support. I really havn't driven it all that much. Replacement brand new 1.5 is $1850 a 2.2 litre is $2400 new. They are getting rare to find these compressors, kennebell doesn't carry them anymore ,they are onto a larger series compressor. PSE is the only one i have been able to find. Started watching E-Bay came across a polished 2.4 Liter , for $1000 bucks with 12,000 miles on it. So I picked that up and going to install onto my 454SS that has a 2.2 liter. The 2.2 is now going to go on the Tahoe ,I think it will be way to much blower , so I'm going to pulley it down to 12 pounds. I have a smaller crankshaft pulley coming 25% underdrive and fairly large blower pulley, and see were she boosts at. I should see a decent HP gain just in pulley ratio and a compressor that is more effciant that won't heat the discharge air as much . Hope to get everything swapped on Saturday.
