Well had a chance to drive the Midi A-arm car I have been working on.
Testing was amazing. Seriously everything went very well.
I had a bit of a problem with the electric fuel pump regulator not stopping the fuel flow enough and so I was flooding bad enough to have fuel actually run out the carburator. So I could not open it up and see what she could really do. Probably a good thing as she is not fully done.
I have a list of things still to do but was at the point where I wanted to test her and make sure she was good to go before I finished everything including the front arms, installed the skid plate, bolted and wired up everything etc.
All the last minute things I didn't want to do if I was still going to be working and still welding on her.
Everything went really well.
Even though I was only able to get about 1/4 to maybe 1/2 throttle or she would flood like I said but that was good enough to run through all the gears and test.
I ran the shocks straight off the shelf so once I can finish everything I can go do some shock valving/testing at speeds and set those up.
The front is incredible! Seriously no bumpsteer and I can drive with one hand on the wheel and the other shifting through the roughest terrain.
The car does not have power steering or even a steering dampner and it steers and handles so awesome you don't need it.
The wheel no matter what you hit does not turn in your hand and you can actually let go of the wheel and it tracks straight. Super happy with this.
I have driven in other a arm cars and they wander and turn etc. sheesh. Just does not leave you feeling secure.
I am happy to say I will use this set up on my mini race car and be totally safe and happy as it steers perfect and easy.
Plus I have heavy truck rims with bead locks on 30 inch mud terrains and it turned easily and you feel no impacts from the heavy rims and tires.
Some details.. The front ended up with over 20 inches of wheel travel and rear just at 20. Front is 82 inches wide to outside of tires and rear is 86 inches wide to outside of tires. With a 103 inch wheel base.
During the testing I used up about 70% of the front wheel travel and about 50% of the rear. Weight not sure yet.. but I know I could feel the difference towing it compared tot he race car.
The motor has so much power that even at half throttle it can seriously light up the 30 inch tires in just about every gear. Just after the first test run on dirt there was no more kitty hairs left on the brand new tires. Stepping up to the 33s will be in the future plans.
Without any adjustments to the shocks the car road very smooth and soaked up everything. The back comes up a bit quick but nothing to bad and again will adjust everything later. Nothing we hit was hard at all.
We went to Barstow and tested on a section of the race course at a pretty rough road crossing. I took the road crossing faster and faster each time.
I was soon taking it 2nd gear easily and 3rd on a last run wide open!
(well as fast as I could with the carb flooding.. ha ha.)
Its so smooth you feel no hard bumps or hits at all as she just soaked up everything and went accross the race course actually very easily.
I have some video from my first pass (its from a camera phone.. mostly just to show its driving. ha ha.) but here is the car crossing it in I think second gear.. You can not even tell the crossing is rough at all.
Plus once I dial in the shocks.. wow. YouTube - 1st test in Midi A-arm Buggy
When I go back for testing and have all skid plates, arms braced etc. I will get new video.
Here are some pics of it also.
I have to say I am very impressed with how well the car did for a first dry run. I have more to do so gremlins could have easily caused troubles and as for the fuel they did a little but over all as far as fabrication, design, size, angles, set up and build of the car I can not be happier with the results.
One of the best feelings was when a friend of mine who has raced in a trophy truck with Travis Pastrana road in it and we hit some of the course and the road crossing in 3rd gear, I saw him hold on. After we went across it so smooth he told me that this was the second best car he has ever been in compared to the trophy truck this little buggy really impressed him.
Thanks for looking
