JRSC belts & pulleys: please discuss it here

I know a lot of us JRSC guys having or had problems with our belts and pulleys and a lot of time we hijacking other threads because of it, so I thought it was a good idea to start up on a thread just about jrsc belts and pulleys. The thread is not only for current jrsc peeps but also for the newbies as well so they won't get us frustrated asking the same question over and over again.

I'll start off with one question, I read around and found a member who is using a goodyear 070775 belt which is 7 rib and 77.5 inches long. I tried a dayco belt that was 77.5 long and it wasn't even anywhere close to fitting onto the 3.4 pulley. The dayco 78.9 belt fit extremely well for the purpose. What I want to know is that anyone else tried the goodyear 77.5 long on a 3.4 pulley or is it because different makers make belt a little bit different in length.

I just called MD where my car is at with JR. They said they did find some problems and they are currently taking a look them one at a time. I believe i VieTEC is currently there so he should be able to give better updates. Unfortunately I had to work so I cannot be there.

I get about 290 mi/tank.
Wonder what kind of problems they found. I don't think it was the installation. I mean between the 3 of us we did a pretty good job, I think. Sorry about all of the trouble you have been having.
Hey Sonny, dont even sweat it! I appriciate all your help! I seriously have no doubt in the job we did! none what so ever!

I just got back from MD Automotive. I was there since 7AM in the morning til about 1:30PM in the afternoon. Mark Wilson drove down with the official Jackson Racing RSX Type S. Mark Dibella is the shop owner who bought the shop from Oscar Jackson when he retired. Keith came soon after. They put Brock's car, JR's car, and my car on 3 consecutive lifts. They examined the similarities and differences of the three cars. They went to work on my car right away. They took numerous measurements of all the pulleys in relation to each other. They determined that my pulleys were misaligned very bad. I had all my pulleys swapped out for brand new pulleys and scissor brackets. I now have new custom machined blower pulleys, brand new metal customed machined idler pulleys, and new washers and spacers to align everything as much as possible. They customed the metal idlers so that the width of the pulleys are wider and higher sidewall to keep the belt from jumping over. The plastic pulleys from before were very narrow to guide the belt. Now the idle pulleys are wide enough to allow the belt to find its own home. They put on custom washers and spacers to move the P/S pump over to the passenger side and other things in opposite ways. Mark Dibella also fixed my Throttle Position Sensor on my TB which was malfunctioning and I had a CEL/MIL of "TPS Low Voltage". I reset my ECU, and loaded my calibration again because my green immobolizer key was flashing for no reason. Once everything was secured as possible they put back on the 7 rib belt and put my car on the dynojet to do an open hood gear run to see how my belt holds up. My belt looked like it was riding on rails. There are other alignment issues with my car but there wasn't enough time and equipment available at the presence to address all the issues. The belt was kinda loose and I guess it was slipping at high rpm. I was instructed to go out for a drive and come back so they can tighten down the belt. My car is a custom prototype deal therefore all the modifications had to be done. It is a base RSX after all. They did the best they could and sent me on my way. Then I went home while they continue working on Brock's car.

Brock's car has alot of the same problems that I was experiencing with my pulleys. If you look very carefully our P/S pump is slightly tilted. They are trying their best to fix his problem. A lot of notes were taken to bring back to JR for future plans and improvements.

JR's own car is a beast. It is in flawless show car condition. Everything on this car is perfectly aligned. The car has been abused on road tracks and strip tracks and you can't get this belt to jump. This car is perfectly tuned and everything works to perfection.

Mark Dibella owner of MD Automotive formerly Oscar Jackson's research & developement center. He is a very knowledgable mechanic who has worked many years with Oscar Jackson. He can do all the install for future JRSC RSX owners.

There is talk of just having a raw engine out of the car with the JRSC kit on it to test the alignment issue and everything else. This is the best way to see all the pulleys working without anything blocking your view or measurements.

Special thanks go out to all the people at Jackson Racing who were there on hot and very humid over 100 degrees weather to help fix my problems. They are still working on Brock's car to find a cure for the Type S.

I have plenty of pictures and a video of today will be posted later

Well I can’t go into detail like Vietech did cause I wasn’t there so I just share what I was told by Mark. He said that my alternator is actually in a different location then theirs is on their 2002 Type-S. It was just enough to make the belt ride too far to the driver side, causing my belt to jump and shred. He told me they put on all new pulleys. The idler pulleys are now deeper and wider, but I don’t know what changes they made to the blower and power steering pulleys. He told me with the adjustments they made I shouldn’t have anymore problems with the belt. He wants me to drive it hard for a couple days and report back to him. I told him that wasn’t going to be a problem :). Their entire team is going to brainstorm on how they are going to fix this issue as well as contact Honda to see what changes have been made from the 2002 model to the 2004 model. They are also looking at pulling the engine out and taking a look that way. I let him know that they are welcome to my car whenever they need it. I hope this will get all of us on the right track. Thanks guys.

P.S. My brain isn’t quit working today so if my sentences don’t make sense I am sorry. I will fix it tomorrow.

There is a good chance they gave you the metal idle pulleys also. I heard them talk about it. It takes awhile to machined the pulley to specs. My problems were very similar to yours. Almost identical but not exactly.
Hey Sonny, I forgot to mention that Mark from JR said the install was rock solid. He said that after they got everything fixed my car was running solid. So NOTHING was wrong with my install.
huh... so the alternator has moved from 2003 to 2004... well that would explain why mine (2002) isnt having the issue. Also, Sonny's is a 2003....

Gee... i'm happy it was that simple. I wonder if they'll change the kit and have one for 2002-03 and another fitment for 2004+. I'm sure they will...

good job guys!
sweet pics!!! i saw that JR car in boost magazine... have it on my desk here... w00t!!!

That is not certain. They have to call Honda to make sure. Just a theory for now.

My datalog...check out the speed

how come my rear bumper is different?
what kind of digital camera do you have?
Yeah. I knew the install was done right. But if the alternator moved, then why is it that I am not having problems. Your car is 2004? My is 2003. I don't see how it could be different. I am going to buy the K24 crank pulley and go steal a laptop to tune my car for 9psi or higher. Tired of 288WHP. Must have more power!!!

we have oem rear kit
i'm thinking of getting that OEM kit for the car... its expensive though.

i need a new clutch first!! :)
Here is a video of a simple gear run on the dyno with my hood open for the engineers to observe the alignment of the belt and flexing of the engine parts...wasn't a full on number run because they didn't even put any sort of fan in front of my car.

As you can see my engine is rock solid with no rocking and the belt is on there very securely.

That big husky gentleman is Keith Tabet of JR, next to him is Mark Wilson of Moss, and Mark Dibella of MD is behind the wheel.
Is there anyone having problems still? It almost seems like this thread died. My problems have dissappered I wonder if all others have also.
