Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

BELT SLIP, a thing of the past now people.



I was privileged to be one of the few at the Branson meet to see this thing up close and personal. It is friggin sweet. Wish I had the money to do that to mine just to say that I have that setup in my car. Jason, once again you well beyond what I think you are capable of doing to a car!!!
 
Thanks Jimmy! (and all others)

More to come, more toooo come my man. :cool:

I was amazed myself after we made it worked. I figured we would have many problems right away, and we did have a few with getting the belt tension right. But I have that corrected now, now its onto getting the belt tracking correctly and more-more testing to insure and prove its durability. Then, it will be released.

Here is the first teaser video of the first start up with the camera rolling, so you can her the sound it makes.

YouTube - Prototype GR8racingfool Cogged belt, The first start up

Keep an eye on the tach. on the dash, no imagine what it sounds like at 3,000 to 6,500 RPM's The trip to, during, and leaving Branson this year was very enjoyable with the sound output from the system. ;) At the end of the video, you can hear a POP sound, that was the tensioner throwing off the belt. Which has been corrected obviously.

Yes more videos to come:th_thumb-up:...once the roads dry out here. Damn IKE and all the major local flooding. :th_thumb-down:

~F~
 


Very nice setup you did there!! I'd consider abandoning my 10-rib setup for a cogged one. Looks great! Congrats on getting it made, keep it up.:th_thumbsup-wink:
 
omg! that is a sweeet setup! cant wait to see a final price! i think my car may have just started to have a slippage problem :-D
 
That is one sweet setup Farns! I didnt get much of a chance to talk to you about it at the Branson meet but looked at it on your car for a while. I too thought of doing this a long time ago but as with all of my other stuff was a back burner project that I just dont have time to play with. It is awesome to see that you got this made and I like how you have the balancer pulley arranged! Congrats for getting it finished and on the car for the meet and was definately sweet to see in person and glad you posted up the pics you did! I know how expensive stuff like that can get and the machine shop I use made some custom pullies for the Saleen mustangs with the M112 and was a prototype pulley with holes drilled in 10 positions I believe all the way around in every one of the 10 rib grooves. IIRC 5 or 10 pullies were made and the price was very steep on it but prototype parts always cost more as it takes time to write the program and set everything up. Congrats again and definately a sweet setup!
 
Thanks Dave!

Very few in the community actually knows what stuff like this costs to get produced. I think we did a very good job for our first one. It at least worked the first time we started it. More than I expected for our first prototype.

I was talking with another company who makes these for Mustangs and Lightnings, and was asking for advice with some of the small issues I was having, and he said something like, "so, you made this from nothing, and got it to actually work the first time?" I said yes, he said, "You suck..."(I laughed) he goes on to say "we spent months to get ours to work, and well over a year to get it to work perfect, you got it damn near right the very first time, we should of been calling you." LOL

He was very cool, and helpful sharing his experiences of their kit and all that was wrong about it to help me develop mine. I figured he wouldn't want to give out his secrets, but he was very open about everything. He helped a lot, to further more answer my questions I had about my design.

This project was kinda my apprenticeship in a machine shop, standing next to the owner working together. I had the eagerness to learn and work for free, and he didn't mind teaching me the tricks of the traits. He told me when we were done that he really enjoyed this project. He said this was the first time in a long time he actually got to create and build something from nothing. Because most of his work always involves fixing or rebuilding from scratch a part that broke, that already existed for many of the local aircraft manufacturers, or the side company's who do outside contract work for the aircraft plants.

He is so cool, he called me later in the week after I had been back from Branson to see how it preformed on the open road. A follow up call to see how things were going, thats just awesome right there.

I'm going to have him help me revamp my nitrous spacer plate I made some 3 years ago for a GenV set up this time, and change a few other things on that. So with luck, by next Branson, I will be more direct port nitrous induction than I ever was. LOL

will this be for sale soon?!?!

Once everything is in perfect working order, they will be offered for sale yes.

You can buy one now if you like unchanged with no updates done to it, but you will have some belt dust to deal with because were working on the belt tracking right now.

~F~
 
that belt wrap thingie that I have seen on here, I know its not going to be a necessity bout would it be a good idea to help with some vibration and some of the tracking issues you speak of?
 
Could help, but I don't like the design of that belt wrap system. I designed one years ago, that used that boat anchor of a coil bracket as its mounting point. Thats more or less to give you more of a wrap around the supercharger pulley.

The tracking I am having issues with is keeping the belt from shifting side to side on the cog pulleys. With a serpentine belt, it just rides in its grooves on track all the time. Well, I have removed those grooves, and now it can float from side to side easily. The only two that keep the belt in track at this time are the tensioner and the large idler below it just above the crank. Those two pulleys have sides on them to help keep the belt in line. They do a good job, but need some more help.

The pulley thats out all by its self that bolts to the coil bracket is currently being redesigned. I started machining on it yesterday as a matter of fact. When finished, it will look something a lot like these:
(not my pictures, just found them to use as an example - mine will be much tricker looking)

I think the main problem is with the actual belt tensioner pulley, as the Timken bearing I used in it is the exact same as the rest of them, same as stock on the I.D. of it, but when the nut is tight, the pulley has play in it still. The post on the tensioner that sticks up is under sized, which is fine for a stock pulley, but I need zero play, so I am going to machine down the stock tensioner's nub, and then make me a shin/sleeve that can go over it, to make it a good solid snug fit. Thats the current plan of attack though.

Thats why this is a prototype. :th_winking: Working out the bugs so others dont have to.

And helps that belts are only $32.00 each shipped to my door. But the guy is starting to hook me up with a cheaper price if I continue to buy more from him. LOL

The cog belt replacements for the Mustang/Lightning kits are around $150.00 a belt. So ya...I did my home work on suppliers for my set up to save money. That...and I get Kevlar reinforced belts at that too. :D
