The fuel injection unit which the Granatellis utilized on their “R5” Bonneville engine was borrowed from ……?…… 1) A Corvette…..2) A Mercedes….3) An Indy Race Car…. or…..4) A Cessna Airplane

“In the trunk”….I like that!! Yes, the Studebaker engines and superchargers were no doubt expendable to the Granatellis! I’ll bet when they finished the impeller blades in the Paxton blowers they used had seen better days!!

Yes… I see that now…. It does seem that there would not be enough room for any type of meaningful filter… Possibly only room for a screen… Thsnks.

Did Paxton install any type of air filtration ahead of the superchargers on the ‘DueCento’ Avanti? Not really a trivia question… I don’t know the answer here, and wondered if anyone out there did know?)

Crude but effective!….Really not so different from the method Avanti Motors used on the ‘84-‘85 models. (and perhaps later?)

As an aside…. I don’t believe the Due Cento R5 Avanti had air cleaners fitted onto its twin Paxton’s… Am I wrong about that?

Hmmm!… I’m a bit confused by the question (what’s new!!)…. I think we are speaking of which was the first pre- production (EX) Stude Avanti fitted at Paxton with an R3 (probably 299CI) engine?… I believe 63R1025 had the air cleaner assy up in front of the radiator, however, of course, that Avanti wasn’t a EX car. Anyway, my guess is there was no air filter, other than possibly a screen to keep the rocks out?

I think Avanti Corp. got it right on the ‘84-‘85 ‘performance’ versions, with twin 4” flex hoses leading from grille covered holes in the lower front valance, on each side of radiator air scoop, with the other ends of those hoses connected directly into the sides of the air cleaner assy.

I figure the ahead of radiator ‘factory’ R3 location started on day one….. Although the factory air filter location, as found in a stock Avanti R2 engine compartment, looks nice, It could not be in a worse location…. right over the exhaust manifold …. as far as performance is concerned…... The main problem with the ‘ahead of radiator’ R3 location… in my humble opinion… is difficult access for routine maintenance…. and also water/snow contamination if an R3 Avanti is/was actually used in everyday driving.

Ha… Good one!

Is there anyone local that you think would treat you fairly on the exhaust/ rear cross install?…..Pretty straightforward jobs for someone with a lift.

That’s it!… The spring pressure

The inch pound force necessary to rotate the drive pulley of a Paxton supercharger is in direct relation to the……?……. on the drive ball assembly.

Your ‘91 is probably the most perfected of the GM chassis Avantis… Truly gorgeous vehicle!

Good question for Lew, the forum administrator.

Good old Massachusetts has always insisted on passenger side lower corner Dwight.

God bless.

Wow!… Very interesting!

Yes a ‘name’ blower rebuilder said 5 lbs……using stock tension spring on arm.

Seven is a tad high!

With a factory ‘top mount’ Paxton Supercharger installation (ala R2 Hawk), belt slippage usually begins to occur at a blower pressure of …?… psi. 1) three….2) five …..3) seven….or….4) nine

That’s where Studebaker put it… but you may have an issue putting it there if your State requires a vehicle inspection sticker be placed at that location!

Wow! you went through heck on that lower shock mount…. but kept swinging until you resolved the issue… Well done!!

I use a really thin oil or a bit of ATF on the moving parts

I run the plastic headlamp covers on my ‘63 for general use, and save a set of NOS glass for?? The plastic covers are the same diameter as the glass… although the original glass covers may be thicker. The gasket should fit around the circumference of the cover. With the four holes in the gasket lined up with the four slots in the plastic (or the glass) covers. The gasket should not be on the outside of the chrome retaining ring.
