sorry to hear that ad.ax

well JR sent me a belt and I have it on since last saturday. My conclusion for why the original belt that came with kit shred on me was because it was loose and jumped over and shredded. I just had the kit for a few days back then so I didn't know how tight is tight.

From personaly experiences with those belt, I found a way to check if the belt is tight enough and it works for me so for those who have hardtime knowing if the belt is tight or not can try this out.

Whenever I put on a new belt, before I really tighten it, I turn the pulley with my hand to make sure the belt get stretch out from every part of its length and not only by the pulley. Now it sits tight on the pulleys, do the "tighten up and idle" routine for a few minutes. Repeat that routine for a few times, gotta be patient on this issue or u gonna regret for not doing it lol. Now to make sure the belt isn't slipping is very easy, turn your AC on(yes you must turn it on during this or u won't notice the belt slipping) and give your steering wheel a full u-turn either to the left or right. Now step on the gas, don't do it lightly, give it a push. If you hear the belt making that squealing noise then stop and get out and give the tensioner bolt about half a turn. Keep doing so until you won't hear the squealing. Once you can't hear the noise anymore, the belt is definely isn't loose or over tighten either. You can do u-turn routine every so often to make sure your belt isn't loose from stretching overtime. It's the easiest way to tell if a belt is loose IMO.

Seams like a good idea, I will try that when I get another new belt...

 

[tt061880]

also, take your car out for a drive after the belt is broke in, if you floor it on 1st or 2nd gear and your boost gauge isn't climbing but dropping down instead then that means your belt is slipping

 

[jsfwds2k]

So does everyones boost gauge keep climbing until 8800 rpms? I thought we should hit max boost at like 6000 or so? I am not so worried if this is the case. Can someone please confirm that the K24 crank pulley is indeed suppose to bump you up to 9 PSI? It seems kind of high to me. I am thinking that if you decrease the size of the blower pulley by a little over .5 inch and get a 2 PSI gain, then I would think if you increase the crank pulley by a little less than .5 inch you should see about the same gain. Add the two together and see about 4 PSI or 9 PSI total. Use the 3 inch blower pulley instead of the 3.4" and see about 11 PSI. Is this theory way off? I am sure there is more to this than I am thinking of. It probably has something to do with the ratios, more than the actual size right? If my theory is correct than I should be around 7 PSI which I am. Which makes me happy!!! If not then there is something wrong with my car and I don't know what it is.?.?.? ARe you people with the 7 PSI pulley hitting max boost earlier than 7500 RPM? Please help. Thanks agian guys.

[uchiha]

mine hit max boost 7psi @ 6000 RPM in 2nd & 3rd gear. haven't tried 4th, 5th.

 

[tt061880]

my car hit very close to 7psi when I am about to hit vtec on 3rd and 6th gear, haven't pay attention to the other gears

 

[jsfwds2k]

I wonder why mine takes so long? I don't think the belt is slipping because the boost keeps going up. Do you guys think I might have a boost leak somewhere?

 

[tt061880]

if you have a leak, your idle would be erratic. Just take your car to a dyno and see what going on with it or get the k-pro and log the data

 

[jsfwds2k]

I have the K-pro but don't know what to look for. Maybe I should just take it to someone who knows what they are doing.

:drool: I wish I had the k-pro

To those JRSC owners with K-Pro.

Have you ever tried to set the "Launch Rev Limiter" to 2500rpm ( just an example).

When you're racing at a track.

Launching at FULL THROTTLE!!!

With the car in 1st gear, clutch fully depressed, full throttle. Rev should stay at 2500rpm and you don't have to hold the rev manually right? Just let go of the clutch to launch the car? Is this an acceptable thing to do or would it harm the car?

I know that the rpm doesn't stay put and actually bounce a lil...it fluctuates a few hundred rpm. This can also be bad for our belt condition.

I plan on testing things like this once I know my belt is good to go. I wonder if Chris ever got any dyno pulls with just the K24 crank? If so, Chris, what did you see boost wise? I was also thinking about this: the Type-r crank pulley is about 5.1 inches and the K24 is about 5.9 inches, therefore the Type-r would see more benefit from the K24 crank than my type-s right? Herts62 is at 11 PSI I believe and he is on the K24 crank and 3.4 inch blower pulley. So I'll probably be around 7 PSI now and when I get the 3.4 inch blower pulley I should be at 9 correct? Anyone help me out here. Am I missing something that is throwing me off or what. I am really running rich and I would love to lean it out with the 3.4 inch blower pulley but I won't if there is something wrong here. I am trying to not mess with the K-pro until I get the pulley and belt situation taken care of. I am just running the 9 PSI 550cc flash and my car isn't seeing 9 PSI and is really rich at the lower end of the tach.

 

[tt061880]

okie folks, I went to the track tonight and got one run. On the second run, I was just heating up the tires and bam I lost my power steering, at this point I know the belt isn't there anymore. I then open up the hood and found the belt wasn't in its place. After a couple seconds, I noticed the bolt that goes in the middle of the longer scissor hand wasn't tight on. I took it out and guess what? That bolt was strip out of the shorter scissor hand. I tried to screw it back on but it was useless since there isn't any thread left on the shorter scissor hand. I went and look for a smaller nut & bolt then tight the scissors back together and made it home. Out of all the parts could go bad, I never thought the thread on the shorter scissor hand would be gone like at. I'm so glad I had a 6 rib belt with me in the car because the bolt was sticking out too far that it would hit the belt if I had a 7 rib on. Now I gotta speak to Keith tomorow about it lol.

 

[i VieTEC]

when I started reading and saw "I went to the track tonight" I was expecting to read 13 seconds time. Sorry to hear about that TT

 

[jsfwds2k]

Join the club! Me and chris are two others that I know of that had the hole strip out. That sucks, I was also expecting 13 sec times.

 

[tt061880]

it's okay guy, at least I got it fix right on the spot and able to drive home lol

 

[i VieTEC]

it must be frustrasting...i know you have hit the track a few times with your new azenis but something always goes wrong...like rain and such

 

[tt061880]

yeah I did get to try it once, the azenis ST115 isn't much better than the stockies, don't get it folks

 

[tt061880]

jamie did JR send u another scissor hand?

 

[Acuraivtec]

T hows the belt man ? is that bolt holding up ?
