280zedx Posted December 26, 2006 Share Posted December 26, 2006 Without a doubt, ditch the v-belt idea. I am having belt slipping issues at the 10psi level (i might be in the 15psi once i figure out how to stop it from slipping) I'm using a 5$ 6 groove pulley that i pulled off some old minivan or something and just centered, drilled and bolted it onto the existing pulley. So far no problems. I also went down the road road you're talking about with the SC on the passenger side. It took alot of bracket fabricating and rewiring (including moving the PS pump down to where the alternator was. The compromise is not having easy access to the spark plugs but i have designed it so that it takes under 20minutes to completely access/change them. If you decide to go M90 look at additional modifications as this will put you in an area of extreme airflow - not a bad thing! good luck. p.s. I hope to have mine back together very shortly and will post info and pics soon. It includes a smaller SC pulley, 440cc injectors, 60mm TB, bigger intercooler and piping, better water injection, custom fuel rail and a complete "facelift" for the intake manifold. -If you want more info on the passenger side supercharger mount, let me know.

OlderThanMe Posted December 26, 2006 Share Posted December 26, 2006 280zdex: you have the coolest supercharged 280zx with an L6 motor I have seen!! It looks an OE supercharged L6 from your open hood shot!! Very clean!!! Quote Link to comment Share on other sites More sharing options...

Do you have more pictures as i still ' plan' (mad idea in my head) on twin charging .. this will be the only way ! How did you fab up the tank you seem to have the same SC ( Pontiac one) .. do you have sound clip s? Just when i figured i did not want to twin charge I LOVE IT !! It seems feasible again So more pics would be helpful .. i only have to feed the turbo into SC .. Sorry for the semi hijack mario!! but i bet you love some pics aswel !

frank280zx Posted December 27, 2006 Share Posted December 27, 2006 ooh and how did you hook up the bypass and all ..any pictures would help tremendously! Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted December 27, 2006 Share Posted December 27, 2006 So how could we hook a SC up to the tranny without too much fab work? You could cut and weld your bellhousing and use the gear off of your old broken starter and hook a belt to the gear (which connects to the flywheel) so that you could change pully sizes. maybe a new thread on twin charging is in order... Mario: what if you mount your SC on the tranny to the input shaft or to the flywheel? That would be Uber cool... *edit* check out this web page about twincharging Quote Link to comment Share on other sites More sharing options...
frank280zx Posted December 27, 2006 Share Posted December 27, 2006 OTM no i want to drive it like the conventional ones .. basically i want exactly the same as mario.. So no need for a new tread if it is up to me. My air filter will only consist of a turbo and some extra piping. The picture looks awkward but it is gear driven on the delta s4 i think .. but back on topic. So Mario correct me if i am wrong .. you want to see sc set ups right ? if you like a new thread let me know .. but i think we want the same info .. i want to see them aswel and love 280zedx his set up .

280zedx Posted December 29, 2006 Share Posted December 29, 2006 Here's a couple pics of the supercharger install for the passenger side. I made a steel bracket to hold the plenum and SC which bolt down to studs welded in place. I made 3 braces along the head side of the bracket that extend down and bolt to the block plus a main brace that bolts under the 2 engine mount bolts. Its solid. The alluminum plenum was simple enough and nothing fancy with a 2 1/2inch outlet. The smaller round hole is for the SC bypass chamber. The supercharger sandwiches the intake plenum and both can be removed easily in order to get at the spark plugs. In the front view pic you can see the changes to the power steering pump and alternator as well as the pulleys. For those that attempt this fiasco, prepare for lots of fabricating. The battery, fuel filter, vacuum bottle, power steering pump, alternator, and part of the wiring harness have to be relocated as well as mods to the fan system, spark plug wires, pulleys and fuel management. I hope this helps. Cheers, Quote Link to comment Share on other sites More sharing options...
z-ya Posted December 29, 2006 Share Posted December 29, 2006 280ZEDX, I really like your setup, nice job on the fabrication. I almost want to mount my JCR SC on that side, just so I can run an air to air intercooler. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted January 5, 2007 Author Share Posted January 5, 2007 Frank no need for another thread as I do want to see people's setups! Everyone thanks for the replies, I just got back from out of town so I won't be able to install it before getting back to college (but I hope I will have shop and welding access there...) so I'm going to try to get MSnS running on my 280z (copying my ZXT setup, already bought the dizzy). OTM, though that idea sounds good, however have you ever heard a bad starter in which the bendix sticks? The non lubricated metal to metal contact of the gear teeth is insanely noisy! 280zedx, your setup is amazing and I've gotten a lot of ideas from it. Right now what I'm thinking is that I want to run the SC in place of the alternator, and put the alternator where the PS pump is on a ZX. One of the difficult things is the size of the M90, it seems a lot bigger then yours based on the pics. It does look like I will have to switch to electric fans to clear the pulley if I do bolt on a serpentine pulley. Any links to mods I can do to the supercharger? Also if possible could you post dimensions of your mount? If I can't fit the SC where the alternator goes I will be mounting it similarly. Other ideas that I've had include running the piping behind the engine, or using a v-belt to serpentine belt adapter, kind of like a v-belt idler with a serpentine pulley bolted to it. I wonder what happened to AZ Zcar's serpentine pulley set... Only ZRaceProducts seems to be offering a serpentine damper but it's like $700!!! I've been wondering if I can find OEM pulleys that I can redrill to switch everything to a serpentine belt... How do you search for OEM serpentine pulleys? Is JY recon the only way? Also, this SC came with the TB (which is huge!) and the MAF sensor is built into it. I think I might just run MSnS-E with MAF support and not run a MAP sensor since most MAF have altitude compensation handled internally. This is kind of important since I will be going from Tucson to Flagstaff a lot, which is almost 5k ft of elevation change. MS is still a little buggy in altitude compensation without adding another MAP sensor. What's nice about the M90 is according to the specs I've seen I just have to spin it 2k rpm less then the M62 and it flows a lot! Also, my SC came with what seems like an electronic valve that seems to control the bypass. So I think I'm going to have a SC switch Kjones and Z-ya, I had plans for a home made JCR type kit, but it would require a custom extension as well as a custom intake. First things first is to install MS to pretty much gut the passenger side of the bay, and switch the fusible links to a fuse box mounted out of the way.

linluv84 Posted January 5, 2007 Share Posted January 5, 2007 I sketched out an idea almost exactly like 280zedx's setup, but simply mounting the supercharger directly where the ps pump would be on a ZX. Running only 8psi I figured I would be able to get away with a v-belt. No fancy pulleys or tensioners required, just a bracket/plenum for the supercharger...

z-ya Posted January 5, 2007 Share Posted January 5, 2007 I'm running 8psi, and like I said, even my 6 groove serpentine belt slips at high RPM when just slightly loose. Find a 6 groove pulley in the junkyard and save yourself some hassles later on. Quote Link to comment Share on other sites More sharing options...
linluv84 Posted January 5, 2007 Share Posted January 5, 2007 No worries now, that was just a thought a while back. Turbocharging seems more feasible now... Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted January 5, 2007 Share Posted January 5, 2007 Mario!!! You MUST put a big red push/pull switch on your shifter for the SC bypass!!! Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted January 18, 2007 Share Posted January 18, 2007 Mario...can't wait to see your setup!!! check this out... some dude's setup I found on zdriver.com (my old Z home before I knew about hybrid) Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted January 18, 2007 Author Share Posted January 18, 2007 Thats awesome but there's so much heat on that side of the engine. I wonder if that would affect the S/c being so close to the headers. Someone posted a link to a ~$75 damper with only one groove and holes drilled and tapped for a custom pulley. I think I might buy one of those and make a pulley that sits in there. Also, preventing slippage is all about tensioner placement. I was looking at a kit for a 06 mustang s/c and the belt almost went all the way around the pulley! From ROUSH I need to make the pulley first to figure out the mounting, and if I can prove to my dad that I can make it without a/c here in Tucson I'll be riping all of that out. I just need to find a place to work... Mario Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted January 18, 2007 Share Posted January 18, 2007 cool...I can't wait to see how your setup turns out Mario!! You can deliver pizza and make around $10-12 an hour but you put miles on your car. I delivered in my Z for a while but then I started brea..er..upgrading stuff.

(goldfish) Posted January 19, 2007 Share Posted January 19, 2007 Just as everyone says read Maximum Boost for turbos, Read Supercharged!, also by Corky Bell, and gives good ideas on how much power is going to be use by the blower, and... well everything else really.

ww Posted February 5, 2007 Share Posted February 5, 2007 That's an impressive fabrication job 280zedx. Has anyone considered using a centrifugal supercharger rather than a roots style? Mounted on the passenger side, I would think the mounting and plumbing would be a little easier to pull off than the roots install. The intake charge would come from the front and the output could be directed out through the passenger side of the radiator mount, into an intercooler and then in through the stock intake hole on the driver's side into the (AFM/MAF/MAP) TB. You could use a "waste-gate" in front of the supercharger intake to act as a turbo-boost bypass valve on the supercharger. You'd still have to figure out how to fit an electric fan in front of all that plumbing though... Quote Link to comment Share on other sites More sharing options...
