https://weddleindustries.com/gear-calculator https://weddleindustries.com/sites/weddleindustries.com/files/downloads/Current Gear Availability 4-1-21.pdf There are a few ways to sort out what gear ratio will work for your specific application. Most trans builders tend to work with a "common" set of ratio's that they know most people are happy with when using common engines and power numbers, but you the individual can make some determinations on what might work for you car the way that you drive it and where it is mostly used. Most typical sand cars will never see more than 100 MPH. If you want the most performance from your engine, you can start by figurin…

My car is almost done at Funco and I think I’d like to have it painted. Has a wrap on it now. All the usual Funco Painters are booked into next year. Anyone know of someone else?

So KarTek and McKenzie's are out of the ProAm 934HD hubs. KarTek said Timken stopped making it and they are looking for a new source. I'm on a list with I don't know how many folks over here in limbo. To add to the frustration there is not a part number anywhere on these and of course you never get a box. I have the parts off the car and a few leads, so tomorrow I'm off to O'Reilly's to ruin some poor guys day. Any suggestions would be appreciated and I would be happy to track it down. Just don't tell me to go to Midboards, that will happen hopefully after the season and not during. Thanks!

I have one CV (934) that some how bonds itself to the CV cup. I can beat on it with a 3 lbs sledge until my arms get tired and it doesn't budge. I have deployed chemicals and thought while I wait for them to work I'd ask what's you method of removing one? I would really like to know how to prevent this before I switch to midboards and can't expose the inside of the CV body.

The official thread for all transaxle related FAQ's and basic information. There is lots of mis-information floating around on the internet, hopefully this one thread will be able to inform all readers and give the correct information. I'll start it off with some basic info on each Weddle Industries produced transaxle. A phone call or e-mail will always be the best way to get the proper and accurate information you need for your specific application. This thread is not limited to Weddle units only, but I will not be able to answer any questions on non-Weddle units. Hopefully some of the other reps can jump in and answer questions on their units. All infor…

Finally got the flex fuel tune all dialed in! The car was setup for flex fuel but originally just tuned on 91. But I had a couple issues getting the e85 tune dialed. First flex fuel sensor issues. Then the O2 sensor failed. The final issue was blown out spark. The stock LS coils “round ones” didn’t have enough juice to keep the spark going at high boost and rpm. I upgraded to the Holley Smart Coil kit with the big wire kit. It solved the issue and I was even able to increase spark plug gap. Here are the 91 numbers to the wheels at 10psi before e85 tune. Holley Smart Coil upgrade E85 dyno run IMG_5204.MP4 Any guess what…

I think it would be nice to have a thread dedicated to all the members running Honda engines. One place to discuss all things Honda. I will kick it off with my current build. Brand new short block and brand new heads. Installed the heads yesterday and now am working on the timing components but having an issue with the timing belt cogs matching up to the drivers side cam gear. any tips on how to align them? They are all at TDC.

Hey guys, So I know the "small, smooth, groove to outboard" guidance: Small [cage]: Small (non-beveled) side of cage goes outboard Smooth [star]: Smooth (flat) side of star goes outboard Groove [housing]: Groove of housing goes outboard However, none of the EMPI 5098-B CV's I have ordered in the past have a groove on the housing. The only visible marking is the printing of the part number on the housing. On my last set of 4, as assembled from the factory, I swear this writing was right-side-up when viewed from outboard side, so I wrote that down in my notes and ran a set that way with no apparent issues (the corners of the stars are chi…

Seems the tools, oil and seals …

Question: Just installed a air to air intercooler to my freshly built 2.5 DOH subaru motor, I installed 3 small puller spal fans and unfortunately my computer does not have a source to tell the fans to come on & off I could wire them with relays and install a dash on & off switch but would rather use a automatic fan switch. Do you guys know of a good quality controller that could handle the 3 fans ?. the fans pull about 5 amps each. I would prefer a probe type because I don't have a bung installed. Thanks in advance Johnny

Okay GD.COM peeps, I have a Subaru 2.5 460HP tuned on race gas and want to convert it to E85. I roughly burn 4 gallons of fuel per run now on race gas. How much additional fuel consumption should I figure on after converting to E85? Also, can I expect a increase in power after a new tune or will the engine remain at the 460HP level? Thanks

Alright guys like most things there is a shortage of parts. I'm trying to get some new 934, 35 spline CV Stars. Does anyone have a connection? I've tried McKenzie's, Kartek, and i even called fortin and no one has any in stock. All are on back order. I might have to just go buy all new cv's just to get the stars but i'm trying to avoid that. Any help is appreciated

I have another thread going on searching for buggy’s for sale. A few have popped up and I’ve seen a few elsewhere that have a PBS transmission. Now I know back in the day that wasn’t a bad deal but now I’ve read a lot about PBS not being good for repairs? Something like you can’t get replacement cases or parts for them? Does this only pertain to certain ones or is it across the board? Thanks

Ok so getting this started. Back in 2007 I got the idea in my head to build a sand car. This was after only camping in tents and riding my quad. Over the years to come I bought several cars and have learned what I wanted and what will work for me. This tread is to document the journey.

Apologize if this has already been discussed, are there other of brand master cylinders that is compatible (plug and play) with CNC hanging pedals? (or is that mounting pattern a universal fit?) Also, has anyone had any luck replacing CNC hanging pedals with another brand that has similar mounting pattern? i.e minimal fab to convert On another note, the Tilton stuff looks pretty nice, with vertical and horizontal adjustments for the pedal, and dual masters for the brake with balance bar. Anyone have an experience with Tilton? https://www.mckenzies.com/products/tilton-800-series-overhung-pedal-assembly?_pos=54&_sid=7fb53a08f&_ss=r Thx!

So I have 934s that have about 8 days of total use (over two years) here at Silver Lake in Michigan. I ripped a CV boot last trip and am cleaning/regreasing them for the first time now. I noticed that the cages have some witness marks in them from the balls. Is this normal, and if not what causes this? I had a shop put these ones in when I bought the car, and so far as I can tell everything was installed correctly. They weren’t clocked inner versus outer exactly, but otherwise appeared fine. Balls/Stars/Bodies look fine, so wear. Figured I’d ask you guys for opinions…. Car is a Desert Dynamics with an NA LS7/S4S and Pro Am stubs in case that matters. Thanks! …

The old site had some good references for batteries. The motor will be a stock J35. Not a huge radio guy. See myself with final upgrades of lights up front and rear chasers, couple whips, maybe radio. So nothing too extreme. I seem to remember the Odyssey PC680 was a good option. Thoughts?

I have a mid travel manx and have been running a 2.5 turbo motor for years without a intercooler and have had no issues, I had a new motor built and now would like to run a intercooler and am looking for some pictures and ideas on where the best placement would be, I know it needs to be in front of the radiator for best performance , With a manx and a windshield I know I am limited , Some pictures would help . If any of you subaru/manx guys out there running intercoolers i could use some pictures & ideas .

Anyone car to school me on drive axles (with u-joints) like the truggy's run. Are they a good idea for lower power cars? In my case, a mid-travel manx with only 300hp? Would be nice to get away from CV maintenance, but not sure about the cost/benefit ratio. Anyhow have a suggested vendor to talk to? Thx!
