AG-R3, is that photo you posted the Prestolite R3 that Booth owns?

That appears to be a 63/64 GT Hawk R2 air cleaner. It is the same as R3 Avanti. The difference is the size of the air hose. Naturally it is larger on the R3. The crankcase ventilation hose would be correct in New York and California even on R3.

I think the photos in the article we all thought was the R3 Avanti were actually the R2 or R1?

I always thought that R3 Avanti was red with a black interior and it turned out to be turquoise with a matching interior.

Back on 1969 $6k was a ton for an Avanti.

Wouldn’t that be great!!!!

Remember, I did say I wouldn’t bet my life on it. However, what do you think a dry sump would look like on the R5. It would need a sump of some sort to accumulate oil that leaks past clearances in moving parts? I imagine that bung in the pan is for oil temperature sensor but could be a pan drain, it does look pretty big? Usually a dry sump is used where hood or ground clearance is a problem and the pan is flat or nearly flat with the pan rails. Also oil in the pan can can eat HP and can produce foam just by whipping through the oil. A dry sump on the R5 would make sense for eating HP but not for too deep a pan causing drag. I’m glad I didn’t commit 100% to that answer. Still not 100% standard oiling system but definitely leaning in that direction.

I remember reading the same thing just don’t remember where. Maybe Andy’s book?

Reginalbob. If the oiling system from the tank via a electric pump supplied oil under pressure directly to the pickup inside the supercharger, would that be considered a dry sump oil system even if the drain back was configured to maintain factory dipstick level?

I’m going from foggy memory but I’m pretty certain the R5 was a dry sump. Though I wouldn’t bet my life. As for dry sump blowers I’ve never heard of it on Paxtons of that era. I do know the Bonneville blowers had an external reservoir of about one gallon. Fluid was pumped,via electron pump, out of the reservoir and into the blower where it overflowed to a 3/4 hose at the full level and gravitated back to the storage tank. It’s been awhile since I had the Bonneville blower apart and I can’t remember if oil was pumped through the blower’s own pickup or just into the case. Either way, they tried to maintain the original oil level judging from the position of the drain.

Yes, I believe the R5 was a dry sump.

Ed. I was going to pose another trivia question which would have been “where was the air cleaner located on the R3 Bonneville record cars”. The answer was going to be “in the trunk” as they didnt run air cleaners at Bonneville at least on the R3’s. I guess they didn’t care if they wore out rings as they simply wanted all the HP they could possibly get.

Geoff has it right. I should have said the HR road test R3 Avanti as there were others. So, 1016’s air cleaner was in the cavity between the inner and outer fender. The air to the air cleaner came from the front grill opening and yes there was a screen over that opening. 1016 was not assigned an EX #.

Where was the air cleaner located on the first R3 prototype Avanti? This is a rerun p/continuation of the question I posed in another/incorrect section of the forum. Sorry.

I guess I put this question in the wrong place. I intended to put it in Avanti trivia. So far, nobody has it right. Moved to Avanti trivia.
