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…

John (outfront) posted on the dead forum about a walker brake he retrofitted in a Funco. I’m looking for that same setup or better. What’s the best steering/walker brake currently on the market? (pic for fun🤩 )

Has anyone ever thought about doing front turning brakes or played around with the idea? What do you think?

I’ve always wanted a water pumper and couldn’t pass this one up! It’s got a 90” wheel base! I’m a VW/Subaru guy, so can any old school duners tell me what I’ve got… engine plate (Chevy/Ford?) Rear End? (welded to the frame!) Steering box (spins smoooth!) I added some extra pics, any other tips/pointers are welcome! Power plant wise I’m thinking a 327 Chevy or maybe an old school aluminum block 215 Oldsmobile? Also, this babies getting a 12 foot Buggy Whip and big American Flag! Oh, and I figure it’s gonna be a wheelie machine with the short WB. I was hoping to be able to drag out busted up SXSs and sand cars with it since it’ll end up with a…

Since switching to E85 a couple years ago I have been running stainless fuel filters. The 100 micron is easy to tell if it is clean. The 10 micron is tough. How are you guys cleaning stainless filters. Ultra sonic, hand cleaning with a solvent, blow out with compressed air, ???

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.

Looking at buying a 2014 S&S 4 seater with an LS2 and a 2D. The car has been sitting for 2 years and something is up with the clutch. The engine fires and runs fine. Can put the car in gear when the car is off and when the car is fired in gear the car wants to take off. Guessing it's a simple as pull the engine and clean up the clutch/flywheel. The slave cylinder seems to move freely. Any pointers? Also looking for suggestions on what clutch setup to go with if it needs replacing. Thanks!

Sure, you gotta wind them up a little, but they were made for it. Promotor Engines is selling Nascar engines to the public due to a recent rule change.

Cant find much info online, but I see a ton of people run them. Noticed they are on pretty pricey vs running a simple pre filter. What is the benefit, lifespan and is it worth it overall to spring for one? FWIW, it would be installed on a Honda 3.5.

Heated subject! What does the future hold for my special construction sandcar w/ boosted performance engine? Will the EPA or CARB seize my vehicle at a check point in Glamis someday soon? Will they go after vendor that supplied me the components and the tune? Numerous street performance shops have been fined and customer records have been seized by the EPA. I’m not finding the level of concern in the off-road community found in the street, drag, drift communities. What are your thoughts on this subject?

Where can I take my Fox shocks to get cleaned and painted? I would also want my coils painted or powder coated. They would have to disassemble and reassemble since I don’t know how. I would need a new sticker also. Who near Whittier/ Los Angeles do you recommend?

I remember there used to be a couple good threads on here about bead sealers…. I used the alumaseal/antifreeze on my last set with some success, but not perfect. Just getting ready to mount new 35.5s and 12.50s and wondering what everyone is using to seal them up? And what mix of antifreeze/alumaseal if using that method. Thanks! -Dave

Lots of different opinions and lots of happy users. Seems one brand doesn't fit for everyone. Curious what the numbers will be here and may help gauge what everyone is happy with or what might show to be the best! Lets Poll

I'm in the middle of rebuilding my fox coilovers all 2.5 with 2.0 piggybacks. Fronts are ibp's but I haven't gotten that far yet. I've looked all over to find a spec for the ifp height but keep coming up empty. When I pulled the first one apart it was only 4 inches down from the top. I knew that wasn't enough but have no idea when the last time they were rebuilt was. I found a rebuild sheet for 2.0 shocks from Fox stating for an 11 inch res to install the ifp 8 inches. So for assembly I filled the res first and let it fill into the main body enough that when I installed the ifp it would push oil into the main body and not have any air in it. I installed the ifp to 8 inche…

Hey everyone I'm sure someone with knowledge on this will chime in but basically I've been told to basically keep my factory intake and that the after market ones are not worth the money for the little Gaines. Can anyone agree to this or show me the difference between the ls3 and say a fast or the high rise ones. Thanks

Ok so I’m about to set up the axles. I remember that ther should be a quarter inch of play at level. Before I make the cut anyone tell me if I’m right?

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 …

The fire system thread got me to thinking and that got me to looking which got me to planning... (name that movie. LOL) My skid plates do not have any holes in them and I was thinking couple of seasons ago I should do that because the sand gets trapped in them, especially where the bars meet the plates. And I guess I never gave much thought to it, but I suppose there is a "skid plate" & a "floor". I was talking generically about the entire bottom of the buggy. the flat aluminum surface where fuel/oil/flammable liquid could be contained inside the car. If sand gets trapped, then spilled fuel would also get trapped, especially if it's got a bunch of san…

So the season is officially over. I started to work out the little bugs of a new car. First thing was a spring change a little valving adjustment. I need to wait awhile to see how we did on the shocks. Next I added an oil cooler. I went with Mocal heat exchanger which should drop oil a decent amount without a significant drop in oil pressure. Finally is the E85 tuning. We had some hiccups at the higher boost levels on E85 where the spark would get blown out with even with a low .016” gap. I am going to upgrade to the smart Holley coils to see if I can fix that. But of course like everything, they are on backorder! Also got a nice set of firecore50 plug wires to…

Looking for the best gear oil for an MD5 and 2D tranny. Weddle and Kartek list the Maxima full synthetic oil, 75W-140, which is the weight that Weddle recommended. I have used the LAT in the past, it says it is a semi synthetic. Torco is also another listed on both sites, full synthetic. And if I remember right, the 2D is 4 qts and the MD5 is 5 qts? thanks Edit to say my buddy says he is using Amsoil 250W severe gear oil full synthetic. He said he runs quieter now? May try it.

So working on my boat project and it's come time to anti up for this hosing..... I did a quick build on anfittings.com and it was over $800. Then went to redhorseperformance and it was $450 It's not really about the price, but I need two systems Oil and Fuel so I'm doing different colors and hose so it looks good and different.

Sorry if this is way long - but I think its important .... Those who have duned with me know I am a freak for fire safety. If you go fast in uncontrolled conditions stuff happens. I have seen first hand what fire can do, and some GD members (LRS comes to mind) have been in off road fires and its not fun. Most Sand cars don't have fuel cells and firewalls, many have windshields, padded interiors and lots of Horsepower. The same is true for a lot of SxS with big power hungry lights and stereos and way more plastic than a sand car. I started over 10 years ago putting fire systems on all my cars and many of my Buddies cars, not because I think a systems c…

If not time, it’s getting close to time to rebuild my FOX 2.0’s I watched some youtube videos so I’m pretty much an expert now .. OK I just watched one video. I’ll need: snapping players or a pick Something to grab the Schrader valve to pull the reservoir caps out, IFP removal tool oil rebuild kit nitrogen bottle and filler gauges thingy probably some more youtube. What else and I missing? I need to figure out what torque setting to crank the shaft retaining nut to and I need the specification for how deep to set the IFP when I fill the shock with oil. Seems the tools, oil and seals …

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.
