240Z_Master Posted June 29, 2005 Share Posted June 29, 2005 Sorry to bring a post up from the dead, but I just got my ATI Dampener today for way below retail! Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted June 29, 2005 Author Share Posted June 29, 2005 Yea, I've got mine on the way since last post. BTW, which unit did you buy? as there are two models, the reg and a race version. The later comes with a alum W/P pully that requires a smaller belt, due to its larger dia. I belive its rated for 600+ hp. Do you (or anyone else for that matter) have a pic of theirs? and with it installed too..... thanks for the update joel Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted June 29, 2005 Share Posted June 29, 2005 This particular one I bought was for the R32. I think the differences between the R32 and the R33/R34 is the offset in the powersteering pulley from what I remember. NOTE: I bought this crank dampener for my ECR33/RB25DET. There are a couple differences. I'll just list a few that I could remember. You can also remove the P/S pulley on the crank dampener which I will do since I have no use for P/S. #1) The P/S pump has like three ribs on the RB25 compared to the RB26 which has like four. #2) Water pump pulley on the 25 is about an inch smaller in diameter than the RB26. [Cavitation issues here maybe?] #3) Alternator pulley is also a tad bit smaller than the RB26. #4) Crank pulley is totally different between the 25 and 26, it's like night and day [but the belts run in the same location and should work fine]. All in all, it's a great upgrade for the 26 guys, and if you're a 25 guy, it won't hurt either unless you run power steering. Does this help anyone!?

AKWIKZ Posted June 29, 2005 Share Posted June 29, 2005 Actually, you don't need to buy their off the shelf one if you don't want to. I had them make a single pulley one as I only need one groove for the water pump and alternator. They did not have a production one like this at the time (almost a year ago) but they made one using a Chevy outer housing. It uses the same style of belt with only a minor difference in the number of grooves. The Nissan one is four groove and the Chevy is six. I ran a similiar set up when I installed the SR20det into my old Roadster. The stock SR alternator was too big so I used one from a Diahatsu of all things. It was from the same maker but about 1/3 smaller. Unfortunately the pulleys were not interchangeable so I had to use the six groove one with the four groove belt. I had no problems at all. Even when I spun it to 9K, ....twice. (when I broke the rear end). Anyhow, the space and weight savings with the single pulley style will be very nice, needless to say the overall cleanliness it gives. I have a couple of pics, but I don't know how to post them here. Someone want to give me some tips on this? Just for reference, my pulley is rated to 800hp with a suggested rebuild every five years. I paid $460 shipped to my door.

AKWIKZ Posted June 29, 2005 Share Posted June 29, 2005 Let's see of this works http://album.hybridz.org/showphoto.php?photo=3099&cat=500&page=1 http://album.hybridz.org/showphoto.php?photo=3100&size=medium&cat=500&page=1 Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted June 29, 2005 Author Share Posted June 29, 2005 thanks for the photos 240z master, it looks to be a well built peice.... I will post a couple when mine arrives. I have another issue I will have to deal with on mine. I run a TEC2 ecu with a 8" (I think) trigger wheel. I will have to figure out a way to mount it to the new damper. This is how I have it set up on the oem RB26 damper, so I should be able to do something close to this. I just hate adding anything onto the ATI to "un ballance" it.... we'll see what happens....

Guest JAMIE T Posted June 29, 2005 Share Posted June 29, 2005 Joel, I'm gonna do the same thing with my SDS. I need to make the magnet trigger wheel. Bolt it to the front where the PS pump pulley bolts to. I'm using the off the shelf damper. It has the pulley for the AC and Alternator plus comes with the pulley for PS.

RB26powered74zcar Posted June 29, 2005 Author Share Posted June 29, 2005 I just spent all the time my body would allow me to this a.m. removing all the intake and exhaust manifolds, and parts that were temporarly put on the motor for the return trip back to me. James did a nice job on fabbing it all up for me, then installed it all temporarly. I will reinstall it all back sooner or later, but with all the Tomei metal gaskets. I also did this work today so that I could mark the area on my air con comp bracket, that needs a hole drilled thru it to allow the external oil pick up fitting. Its going to be fairly easy from what I see. Then I still have to remove the new reg oem oil pump on it now, to replace it with the Greddy oil pump... After I bore the hole in the bracket, I will snap a pic for the archives, in case others may want to do this later down the line.... As far as the ATI damper, mines a off the shelf one now also, its just the race version rated a bit higher rpm than the one below it. I would have just bought that one, cause I'm not planing on using this motor to its potintial. I can't see needing this version dampner, its just James got them at a fair price since he bought in bulk, so I got it for the price of the lower rated damper. I may be able to do as you are with the trigger wheel, since I will not need the outer pully. I hope to mount it there, its just the ballance part that worries me with adding the wheel to a ballanced damper.... Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted June 29, 2005 Share Posted June 29, 2005 I think the weight is so minor that it souldn't make any differance. I mean, my stock balancer had been drilled and had the magnets installed for the SDS. I don't suppose Matt would have done that if it would have upset the balance. Adding a wheel to the front of the balancer doesn't effect the balance unless all the weight is offset. If the wheel is round and the holes are all center properly, then it should't be an issue.

240Z_Master Posted June 30, 2005 Share Posted June 30, 2005 Well weight i'm sure is minimal, I think it was like 2 lbs from stock [on the RB25]. I noticed the 26 pulley was a lot bigger and heavier than the RB25. So on the RB26 it could make minimal differences but for us 25 guys it could be a lot? Not sure. 2 Lbs whilst it may not seem like a lot, but maybe with the lightened flywheel i'm adding could make a difference. But I haven't really ran stock to figure out what it feels like, but what the heck, out with the old in with the new. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted June 30, 2005 Author Share Posted June 30, 2005 the weight I've been refering to is not the weight of damper, but what adding a trigger wheel to a perfectly ballanced part will cause as far as ballance goes....

240Z_Master Posted June 30, 2005 Share Posted June 30, 2005 Ooh oh oh, sorry, didn't understand, thanks for clearning that up. Quote Link to comment Share on other sites More sharing options...
ZXRockie Posted June 30, 2005 Share Posted June 30, 2005 So could either one post the P/N of both ATI's damper:confused2 and where to get it from at the best price. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted June 30, 2005 Author Share Posted June 30, 2005 I just had this hand delivered from James. Its the 800hp version, which has a smaller rear pully, to go with the W/P pully thats provided. The only gripe I noticed after the purchase, is that this damper has no timming marks etched into the part.... other than that minor issue, it looks to be a kick a$$ part.

Schlasken Posted July 1, 2005 Share Posted July 1, 2005 maybe i`m stupid but what does this thing do? is it just a ballanced crank pully or does it do something? Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted July 1, 2005 Share Posted July 1, 2005 It is a balanced crank pulley/balancer. But it's bolted together so it can fail at high rpm like bonded balancers. If you you are unfamiliar, the RB motors have a crank pulley/balncer combo. It's one unit. This unit is SFI approved. and rated to over 9K rpm. The race units are rated to 800 HP, and the regular one is rated to 600 hp. You can go over that, just can't blame the balancer if the motor lets go, LOL.
