kamikazez Posted May 2, 2009 Share Posted May 2, 2009 so im moving forward with my supercharged z project and was wondering if anyone could tell me if this looks ok. i realize it needs new teflon strips and i managed to locate a set. im really just concerned particularly about the rotor and what you can see of the casing. thanks in advance to any replies.

G-rib-73-240z Posted May 2, 2009 Share Posted May 2, 2009 what kinda supercharger is it? looks like some type of variation of a whipple but we dont use teflon strips as a sealer. Is it a roots style or a twin screw? i honostly cant see much from your pics, im not a "master" about it or nothign or wanna come off as one, but id say have a certified person rebuild it, new bearing teflon strips, and gears, but you prolly already know that much. while its appart you could probably get it polished or powdercoated whatever your poisen is. edit; does it say b&m on there? and looks like a roots style to me Quote Link to comment Share on other sites More sharing options...
kamikazez Posted May 2, 2009 Author Share Posted May 2, 2009 its a b&m 144 and i believe it is the vein type supercharger. its the same as the holley and weiand 144 Quote Link to comment Share on other sites More sharing options...
kamikazez Posted May 2, 2009 Author Share Posted May 2, 2009 ya it says b&m 144 on the case. im having a hard time find out what drive type it is but it doesnt look angled enough to be a twin screw. Quote Link to comment Share on other sites More sharing options...
G-rib-73-240z Posted May 2, 2009 Share Posted May 2, 2009 doesnt look twisted enogh to be a twin screw so im thinking its a roots should be 3 blades or w/e on each side if it was twin screw itd be like 5 on 3 if i remember right or some wierd set up. i hurd roots have a tendency for the manifold presure to get to high and it starts leaking backwards threw the blower, but i think if it uses that teflon strips it doesnt let the manifold pressure back out of the blower when it becomes to great but im not sure. I not a genious and such, just going off random stuff i learn from my work and internet reading, ya know? should stll be a good fun to run set up. I was personaly thinking about doing a set up similar but i didnt want to owe my boss money for a blower and all that jazz and knowing my luck id end up wraping my 240 around a light pole or something.

kamikazez Posted May 2, 2009 Author Share Posted May 2, 2009 lol i hear ya on that. so far my setup is a sbc 355 8.5:1 compression. i just wanna make sure the rotors look ok for normal wear and tear and that im not buying a door stop, that and im buildin this from scratch and dont wanna grenade it the first time i fire it up Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted May 2, 2009 Share Posted May 2, 2009 I would call RBS Superchargers and talk to JR. They probably rebuild them and the website can give you an estimate on how much it would cost. http://www.rbssuperchargers.com Complete Blower Restrip: Prices starting at $350.00 Includes 4 seals, teflon and nylatron, inspected and clean blower, check timing and all surfaces of supercharger. I have used them twice and now I use Littlefield. John Quote Link to comment Share on other sites More sharing options...
jt1 Posted May 2, 2009 Share Posted May 2, 2009 From what can be seen in the pics, it looks fine. However, only a teardown and complete inspection will tell for sure. jt Quote Link to comment Share on other sites More sharing options...
kamikazez Posted May 2, 2009 Author Share Posted May 2, 2009 cool guys thanks, this guy has a really good rep selling race stuff, and from what hes told me the unit came off a running motor that lost a lower bearing (overboost on a stock 10:1 motor). he says it turns by hand with no binding and looks like it was taken care of. the front shaft doesnt has play and the rotors dont clank when its turned. i think im gonna go for it, im getting a holley double pumper, the blower, the intake manifold and a full stackf fuel chiller, and ill have to find a lower pulley somewhere (holley has em but man 200 bucks for a pulley?????). anything else you guys can think ill need for this setup?i was reading something about guys venting the crank case into the exhaust, but i would think the exhaust would have more pressure than the motor would Quote Link to comment Share on other sites More sharing options...
jt1 Posted May 2, 2009 Share Posted May 2, 2009 I would suggest some more research to figure out exactly what you're going to need before buying an incomplete setup. Then you won't have any ugly surprises. By the time you buy all the missing pieces, it may not be much of a good deal. jt Quote Link to comment Share on other sites More sharing options...

kamikazez Posted May 3, 2009 Author Share Posted May 3, 2009 thus far the block is at the machine shop. its being reslugged 30 over with dished hyper pistons (sealed power) and chrome molly rings. i picked up a set of edelbrock 202 575 lift heads that have been ported and polished and flowbenched. These are the same heads that edelbrock sells on thier supercharged crate motor. crank has just had a fresh turn to 10/10. picked up a true double roller timing set. got a head stud set in the 190k psi range. im currently looking for a set of roller tip arms but havent decided on 1.5 or 1.6 and im not gonna buy the cheap ass ones. ive got a street chiller intercooler and a holley double pumper carb. im still deciding on which ignition box i want but im leaning towards the msd, the mallory just seems outrageous. cam grind is still up in the air, but ill need it soon to start checking valve/piston clearances. thus far my compression comes out to 8.5:1 and i can mod that a little by throwing in a thicker or thinner gasket. im planning on running 6-8psi boost. from what ive heard the 144 is good up to 10, is that correct?

jt1 Posted May 3, 2009 Share Posted May 3, 2009 A set of forged pistons would be better for a blown motor. The hypers won't tolerate much detonation. jt Quote Link to comment Share on other sites More sharing options...
kamikazez Posted May 4, 2009 Author Share Posted May 4, 2009 ya i know on the pistons, but as long as you run good gas, keep the mix rich and retard the timing a degree or 2 every few pounds of boost everything should fly right. i do agree that the forged would be better, but i just cant dish that kinda cash out yet.
