Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / August 2007Paxton SN60 supercharger
Any info on why a Paxton SN60 rebuild would need to be put in us within 6 months? I have less than 1000 miles on the rebuild from Craig at Paradis Wheels and am being told that another one is needed $$$ because i sat before being used. The unit is from a 1965 Excalibur roadster as a factory option Tks / Scott S On Aug 14, 11:34 am, maximo...@charter-dot-net.no-spam.invalid > Any info on why a Paxton SN60 rebuild would need to be put in use > within 6 months?

However, I would pose the question to both Paxton and the rebuilder directly. Ask if there are any precautions that should be taken before using the unit you described. Be sure to note that it was stored after use. > On Aug 14, 11:34 am, maximo...@charter-dot-net.no-spam.invalid > [quoted text clipped - 12 lines] > before using the unit you described.

I assume that they *are* the rebuilder. you might want to check over at alt.autos.studebaker and check with some of the hi-po gurus over there like Ted Harbit or Fairborn Studebaker. good luck nate > maximosca wrote > Any info on why a Paxton SN60 rebuild would need to be put in us within 6 months? > I have less than 1000 miles on the rebuild from Craig at Paradis Wheels and am being told that another one is needed $$$ because i sat before being used. > The unit is from a 1965 Excalibur roadster as a factory option > Tks / Scott S Great, thanks for the leads We'll see how things go with Paradise Wheels....according to Craig Paxton only had a 6 month warranty on their blowers because of th flat spots that would develop from inactivity He admits that it is unusual, other people I am speaking to have neve heard of such a thing Scott S On Aug 15, 12:28 am, maximo...@charter-dot-net.no-spam.invalid > > Any info on why a Paxton SN60 rebuild would need to be put in use > within 6 months?

I have not heard that, is it the balls or the races that they say go flat? Again, I'd ask someone else... in addition to the names I mentioned in my previous post, Jon Myer and John Erb (if he is still in business) might be good people to talk to. at least some of these should be found on studebakervendors.com > He admits that it is unusual, other people I am speaking to have never > heard of such a thing. > Scott S. Just curious, does a '65 Excalibur have a Studebaker engine, or something else? I just ASSumed Studebaker since you are talking about a Paxton. If so, it is probably pretty much the same as an R2 Avanti engine. If not, Studebaker guys are still a good source of info. on the care and feeding of SN series Paxtons, as they were factory options in '63 and '64. nate On Aug 15, 12:28 am, maximo...@charter-dot-net.no-spam.invalid > > Any info on why a Paxton SN60 rebuild would need to be put in use > within 6 months?

Since a supercharger is really little more than an air compressor I'm concerned about that statement. The only things I can think of that could flatten out would be the rotors or the bearings in which they run. Considering the stress and speed that a supercharger has to run under I would think that simply sitting still should have no effect. Seals I suppose could dry out, but over 6 months? Something is really strange about his answer. Or it could be that he just wants to sell you another rebuild job. > He admits that it is unusual, other people I am speaking to have never > heard of such a thing. > Scott S. > On Aug 15, 12:28 am, maximo...@charter-dot-net.no-spam.invalid > [quoted text clipped - 21 lines] > Something is really strange about his answer.

I am assuming that he is talking about the drive system - it uses a ball and race system to step up the speed of the impeller at about a 5:1 ratio and is highly dependent on friction provided by spring preload. Both parts are steel, though, so it does sound a little odd to me. Just as an aside, regular fluid changes are a must and I've been told that Type F transmission fluid provides a little more grip for the ball drive system than Dexron. I would bet, but have no experience, that a synthetic Type F like Red Line would provide the best performance and durability. I have an Avanti engine in my '55 Stude coupe, but the unblown version (would like to convert it someday after I become independently wealthy though) nate > maximosca wrote > Any info on why a Paxton SN60 rebuild would need to be put in us within 6 months? > I have less than 1000 miles on the rebuild from Craig at Paradis Wheels and am being told that another one is needed $$$ because i sat before being used. > The unit is from a 1965 Excalibur roadster as a factory option > Tks / Scott S Nate - thanks again, will chase those The 1964 Excalibur prototype had a Studebaker engine with the Paxto blower using a modified Lark chassis. This was because Studebake had commissioned Brooks Stevens to design the car. Studebaker pulle their support just before the 1964 Worlds Fair in NY but the car wa displayed anyway. When orders came in, one was from the Chevy deale in Manhattan who asked if it could be powered by Chevy. When the car first went into production in 1965, they had 327 Corvette engine an drivetrain The same Paxton supercharger and Studebaker 4 bbl carburetor were use for the optional supercharger only on the roadster model. There wer about 11 cars built with this option. An unusual combination, bu what performance ! About 400hp on 1900lbs Later the models got bigger and different Chevy engines were used.

[quoted text clipped - 19 lines] > Later the models got bigger and different Chevy engines were used. > Scott S. That's gotta be incredible.... I once drove a '71 Avanti II with the same engine with an aftermarket Paxton kit added (that one had a Holley carb mounted in a Studebaker "R3" pressure box.) Even with a 3.08 rear it was scary fast. I never tried a full effort acceleration run in it but when driving it home for a friend I was driving his "normal" car and he was driving the Avanti, and he passed me at about 80 MPH, downshifted to third, and just pulled away like I was standing still. That's got to be rediculous fun in something like an Excalibur... I thought there was more than one Excalibur built with an R-2 again, or am I simply smoking the crack and thinking of the prototype that you refer to? nate > maximosca wrote > Any info on why a Paxton SN60 rebuild would need to be put in us within 6 months? > I have less than 1000 miles on the rebuild from Craig at Paradis Wheels and am being told that another one is needed $$$ because i sat before being used. > The unit is from a 1965 Excalibur roadster as a factory option > Tks / Scott S Nate - only one prototype was built using Studebaker engine. All production cars used Chevy engine / G drivetrains. In fact, Excalibur is the only outside automobil company to be licensed to use these parts by GM Type F fluid is recommended and was used. Again, there were only few hundred miles on the blower when I removed it to send it back The supercharger / engine combo is quick indeed. Lots of fu eventhough I am still breaking in the engine. Keeping it belo 4500rpm but the power is still really impressive Tks again for your help / Scot On Aug 17, 12:05 pm, maximo...@charter-dot-net.no-spam.invalid > > Any info on why a Paxton SN60 rebuild would need to be put in use > within 6 months? [quoted text clipped - 17 lines] > > Tks again for your help / Scott I beg to differ - there *was* at least one other, namely Studebaker itself! they used McKinnon (Chevy) engines in '65 and '66. Also the Newman/Altman Avanti II used 'vette motors but with the same Borg-Warner transmissions that the original Studebaker version used (remember, they had separate bellhousings, and also were used in the 65-66 Studebaker cars.) Not sure how they procured them though, if they "officially" bought them from GM or just bought them through the same channels that you or I would use to get a replacement GM engine. your automotive trivia for the day... nate |
