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…

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…

I know they say run the adjuster all the way closed and then count how many turns out ,but where is the limit of how far out you can go and still be in the adjustment range ? How many full 360 degree turns out from the fully closed position? Hope this makes sense.

Well, things are going in the right direction... I’m putting things back on the car. This is about as stripped as it got: I got the transmission and new CV’s back from the builder a few weeks ago and installed the trans and new CVs and bought new axels because there was some question as to if they had been turned around... and for good measure, I stopped at Kartek for some washers and stub axel bearings and they sold me a new set of one piece chromoly stub axles. One piece stub axles Great big fan for my 14” X 14” setrab oil cooler We did the math and used a calculator …

Hi guys, As the title says, I am upgrading my ECU to AEM and have a couple questions concerning the wires that are attached in the far left plug location and are hot glued into place. I assume I will need to use these wires in the new ECU but is there a cleaner way? does anyone sell that harness plug? I can try to remove the hot glue but do we know which pins are being used? Thanks in advance

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.

@lincster brought in some centerboard hubs for rebuild for a friend of his earlier this week. These hubs definitely had some miles on them but if they are properly maintained they will last a long time. After tearing apart and inspecting, everything was in pretty good shape. Just knocked down some sharp edges on the hubs and CV joints then re assembled with fresh grease and seals.

This summer I decided to swap my Turbo Honda for an LS1. The engine came out of a running sand car before it was pulled out. I have two thoughts and I am looking for direction before I start to replace a bunch of stuff. After filling the radiator and expansion tank, I fired up the engine and let it warm up. The needle on the gauge hovers just under 210* at idle sitting in the garage with an ambient temp of 100*-105*. If I let it sit for 15-20 minutes, the gauge temp will slowly start to increase, and the engine will get hot (it goes to the line between 210 and 250) and then I shut it down. If I take it out on the road, the engine starts to get hot even while cruising at 2…

HI All, Water pump on my car is starting to squeel so i am going to replace it but it has the fan temp switch in one of the heater core ports and the other port is just plugged. Does anyone make a pump that has these threaded already or am i better off buying one and tapping myself. Can only find one that has the heater core nipples prethreaded but the reviews dont look good. talked to the original owner and he said CBM did the water pump last so i was going to call them and find out Monday but thought that i would ask here as well.

I need to shorten my tierods by 1.5” on each one. Switched the type of spindle I’m using. Not sure if just cutting off 3/4” on each side will hurt the integrity. If so should I replace with aluminum or steel? thoughts and opinions…

Wife has a 2017 Colorado ZR2 with 25000 mile on it and one of the rear shocks blew. Tore it off and figured I'd rebuild it, but can't find seals. The main seal was cracked and brittle. Can't believe the seal is only 4 or 5 years old. Anyway I can send them in and have them rebuilt for over 3800 a set exchange, ripoff. Anyone know where to buy seals for these things. If not switching to King.

The other day I was contemplating comp cutting my 14.50 STU Dune Sports. Shedding some rotating weight would be nice and the thought of "lighting up the rear" quicker in turns sounds nice. I started to wonder though if by thinning the tire, it would change the way it slides. I have a Gen 3 Funco and obviously sliding is key to the way this car performs. Anyone have any experience comp cutting Dune sports? Question 2) In General, How many of you are fans of Comp cut tires? also Why or Why not?

I got a weird situation happening and was hoping maybe someone has experienced this or dealt with this before. When I had my car tuned, the tuner told me the coolant temp sensor was not working. He was able to bypass this and still tune the car. Fast forward, I replaced the sensor and now the car is still having showing a coolant temp fault. Here is where it gets weird, if I plug in my OEM ECU it reads just fine, showing ambient temp and will raise or lower as needed. I have tested 3 different sensors and they all have the same fault. I sent the ECU to AEM and they replaced a burnt resistor and said everything is functional. Plugged it in today after …

Ok, I don't normally have a saggy shaft but... I've finally found a way to get my e-steeeing in, and in the course of 3 different u-joint points it has a sag in the middle area where it bottoms to the frame. How can I get it up? LOL trying to avoid the heim mount as it would need to slide in before final weld on shaft ends and then how are they screwed to a base etc. Why am I struggling here. This is baffling me. I had charlynn on my last car and don't want to run it anymore. For sale charlynn LS1 setup too.

I'm considering putting an Eaton M90 blower on my J32a2. The blowers come off of Pontiacs and other GM cars and are abundant and inexpensive. I'm running an AEM computer so the tuning is possible. Prank sells an adapter kit to mount the blower which looks pretty straight forward. Anybody have experience with this type of thing? Im looking for any suggestions other than the standard, "swap in an LS" 🙂

Any tricks to cleaning the inside of an aluminum radiator? On the car we bought, the guy that put it together used carbon steel tubing for the coolant lines. I pulled those and flushed the engine and radiator best I could so far. I'm switching to use Stainless tubing for the coolant lines, but I want to clean out the radiator and engine best I can.

I recently purchased a project build that was never finished. I am working on the rear drivetrain and have a question. my rear diff has a flange on each side with part number 16-2303-7 on them and the flanges on the hub measure to be the same. My question is what kind of axles do I order? What make and model vehicle would these be a match to for axles. Thank you for any help

When I was at the dyno shop last week, they stripped a wheel stud out of the hub when removing the wheels. All the knurling is gone. Is there any way to repair it and get the stud back in? Or am I going to have to purchase new hubs? Thanks

Hey peeps, need some ideas. Funco Gen 4 Turbo Honda 3.5. I bought this car 5 years ago or so, and I have never liked how all the hot wires are attached. I have 4 wires coming off the hot Starter post (powering computer, and maybe fans, hard to tell they are all in a loom headed to ECU and Relays), I also have 3 more hot wires off the battery (I think running radio, and something else). My question, maybe Funco specific, where are people putting bus bars, I would like to clean up this all up if possible. I currently have tranny and engine out, so much easier to do now. There is no room under rear seat (fuel tank). So where is everyone putting these bus bars? An…

I installed the Jamar pro x micro stub kit on my car 3 years ago. So after three seasons with the car jacked up there is a tiny bit of play on one side. At what point do you look at pulling them apart and replacing? Or how much play until they completely fail?
