I need to ask a really silly question, please...

[MagikDraggin]

I have not had a lot of success in figuring out just what the designations R1, R2, R3 and R4 mean and what their significance is, relative to what model and year Studebakers.

Could, would, someone please help me out here?

Thanks in advance

R series engines were a option on 63/64 Studebaker Larks and Hawks. They are basically the same engines offered in the Avanti. I'll let someone else cut and paste all the differences, several hundred R1 and R2's were sold in Lark's/Hawk's. only one each of the R3 and R4.

Allright, I'll give it a try...

The R series engines came out in '63, for the new Avanti.
R1 was a 'hopped up' 289. -235hp
R2 was the same with a Paxton SN60 blower -289hp
R3 was a 289 bored to 304 with a Paxton SN60 -335hp
R4 was a 304 with dual 4 barrels. -289hp
R5 (experimental) was an R4 with two Paxtons. (Or was that one fuel injected?) -hp is still a mystery.[?]


They were named numerically in the order they were developed. Anyone know what the "R" stands for?

That's pretty much the basics. [:I]

Here's an excellent thread on the R3-4's over on Sonny's site.

I'm no expert, but...

R1 and R2 engines were 289 cubic inches.

R1's were normally aspirated, single 4 barrel, high compression (>10/1), special cam. Made about 240 HP.

R2's were supercharged, lower compression that R1's, made about 290 HP.

R3's and R4's were VERY limited production and 304.5 cubic inches. They had special cast iron headers. Horsepower guesses are all over the board for these engines, but they were substantially more powerful than the R1's and R2's.

The R3 was supercharged with a "pressure box" system rather than the R2's blow through system.

R4's were normally aspirated with 2 four barrels.

Karl a pre 63 supercharged Stude would be a Golden Hawk 1957 &1958 if original, if not original it could be a 41 Champion

You got it. The R series engines were only available (from the factory) in '63-64. Paxton Products sold 'kits' for years afterwards, until they ran out. I know of a couple R3 cars around that the engine's came from Paxton.

Matthew,
Your question on what the "R" stands for: I talked to Andy Granatelli several years ago and asked him that very same question. His answer was that the "R" stood for "race".
