Hey guys, I'm building a blown 460 for my 29 Sedan, and need some help with the Blower pulleys. I want to run a 3 inch wide Gilmer setup and maybe a 2 grove V belt setup for the water pump and alternator and fan. This is my first blower motor and I'm not real sure what I should be looking for. I'm thinking I need a V belt pulley to bolt to the balancer, and the Gilmer pulley will fit inside the V belt pulley and they will all bolt down together ? Does anyone run such a setup I can get some pictures of ? I plan on running the mechanical fan, Thanks for the help, as always ....
All kinds here http://www.ebay.com/sch/i.html?_fro...ercharger+accesory+drive+&ghostText=&_sacat=0 You want a blower crank hub, it's free of the balance mechanism. The v belt pulley has a male and female register to align the blower hub to the 3" blower belt thru the v belt drive. 6 holes and bolts together like a sandwich
That's how it's usually done these days, you just stack the hub, V pulley(s), spacers, and Gilmer pulley so they all end up in the right place. You can buy spacers in different thicknesses as needed. I went to 2" belt after years of 3" belt, both to make it more oldy, and to save space for the fan.
Also running a 2 inch belt. Did not have enough room for the 3 inch. DYERS has what ever you need, great service, and great products and advise.
Hey guys, thanks very much for the help, So Im thinking that since the V belt runs behind the blower pulley, how does it drive the fan ?
Thanks squirrel, I want to run a mechanical fan too. Do you by any chance have a better picture of how your pulley and belts run ?
Thanks squirrel, thats exactly what i wanted to see. Think Ill be thinking about running a 2 inch belt also, it does give you the room needed for the fan. Guess youve had no issues with the 2 inch belt ? Ive never ran a blower, and I was wondering if theres ever any issues with breaking belts ?
If alignment is good, then belts last a long time. I've never broke one, over 100k miles. I have worn out a couple sets of pulleys. If you plan to put a lot of miles on it, get them hard anodized.
Are your top and bottom pulleys the same size ? And how much boost are you running ? I plan on driving it alot, I drive my 50F1 or my 29 Roadster every day, but my wife and kids cry alot couse they cant ride with me all at the same time, lol ... Hey damn, are all them cars and pickups on your website yours ?
They're all mine, except the ones I don't have any more. Right now, I have the 55, 57 suburban, 59 orange pickup, 62 Chevy II, 55 Bread truck, and my wife has her Dart, Prowler, and a couple other late models. I'm running around 8-10 lbs boost right now, several more teeth on the lower pulley. Most of the miles I put on the 454 I had in the truck, then the 55, were with it 3% over, about 6 psi
lol, your as bad if not worse than me,, Ive got a 29 roadster a 29 tudor sedan, im putting the blown 472 in, got a 30 pickup, and a 48 and 50 pickup.. So Im putting a 871 on a 60 over 460, in a 29 sedan, how much boost do you think it would make running both pulleys the same size ?
