greg g Posted October 13, 2010 Report Share Posted October 13, 2010 (edited) Graham, and Kaiser used them so why not. Probably wouldn't go much more than 6 or 8 lbs of boost. On a stock motor it would have the effect similar to raising the compression ratio from 6 to 7 to 1 to 8 + to 1. The numbers on the Grahams a 218 L6 went from 87 hp to 125. The Continental engine in the Kaiser (226 cu in) went from 118 hp to 140. The Graham Paige used a in house or made for them cetrifigul oil cooled super charger with a draw through carb set up, and the kaiser used a paxton unit and a blow through carb mounten in a pressure vessel similar to what was used on Avantis. the problem witht he draw through system is that it reached a deminishing return situation in that the more you compress the intake charge the hotter it gets and the less effective it is. But its been done . Edited October 13, 2010 by greg g Quote Link to comment Share on other sites More sharing options...
John Mathias Posted October 13, 2010 Report Share Posted October 13, 2010 Of course I think it's cool! Mainly due to the fact I'm putting one on mine. Going to be running a Fenton dual intake with the 2bbl carbs, Fenton alum head with the Mcculluch SN60 supercharger. Going to have a cr of 8.5 prior to the S.C. so that ought to raise to 10:1 give or take. Been told by some old racers in the area, they used to run up to 13:1 cr on the track w/o a supercharger, but they did have to re-ring every month. Will get into the math later after I get the mounting brackets and pulleys. Long way to go yet, block has yet to be machined. Quote Link to comment Share on other sites More sharing options...
HotRodTractor Posted October 13, 2010 Report Share Posted October 13, 2010 Long term plans for my 265 engine include an SN60 blower - talked with John Erb about it a few weeks ago - but that is going to have to come later since I am doing so much with the engine at the moment that I want it running and dialed in before I add another variable. I figure a 265 Chrysler Industrial with triple Stromberg 81s on my own custom intake setup for good distribution to run them in a progressive setup is as much as I want to get into for this winter with the engine considering I am building a full chassis for the truck to sit on to get all the features that I want. (IFS, disc brakes, lower ride height, etc....). I know its not as original as some would like to see - but I plan on using this truck as a fair weather daily driver with the flathead engine - and I put over 600 miles a week on a vehicle just for work if I don't go anywhere...
