Jon Holders turbo car

Well I have to admit I'm jealous. If I had 100K to blow on a club racecar I would build one too. If I had 200K I would just buy a used Porsche Cup car but thats a different story. Look at his handwork and how akward it is due to his brain sensing the opposite lock he is going to add after the apex. I dunno, it is sort of unbalanced from the looks inside the car, not my thing. Rather would have 400HP of NA then 600HP of boosted power.

Oh and addition to that you figure a guy that races amoung the top 3-4 best prepared BMWs in BMWCCA would know how to heal/toe. I'm not going to make fun as one of my best friends has a CM car and doesn't heal/toe either but CMON NOW!

M Coupe Developments

Wow, moving has thrown a huge monkey wrench into suspension developement but I guess May isn't too late to get things going. For the last couple weekends I have been working on repairing my rear subframe from the removal of my previous eccentric bushing kit from Ireland Engineering and pressing in solid aluminum bushings. Also I have customized my rear trailing arms with the addition of a 5/8 heim joint replacing one of the bushing arms. This will allow me to adjust toe without changing the rear sweep angle. Due to my lack of data as far as loadings on this area I decided on using the PRM line of bearings from Aurora which are rated 10%-15% higher than the normal allow bearings. They actually turned out really well. 7 hours of welding, grinding, painting, and working on the lathe later, I was done. I have to admit it turned out nicer than I had thought when starting. Next week I'm putting everything back in addition to a delrin diff bushing and then working on the front control arms. I'll be doing more lathe work making aluminum bearing cups and spindle spacers. I'll be using 5/8 spherical bearings to replace the out ball joing. My design is a copy of other popular designs that puts the bolt into sheer. I've seen another design that uses the spacer to transfer the sheer forces and a tension bolt to hold everything together but the spacer could fatigue and fail too. So you are better off just replacing the bolt every 2 years or so. For mock and testing I'll be using Grade 8 bolts but after I figure out the final length I'll be ordering AN bolts aka. mil spec hardware. This would be a good idea as I would like the bolt to be stronger than the bearing so we are looking at minimum sheer loadings of 18000 lbs or so.
