Previous Update

Since I was still waiting for the new master cylinder to arrive I concentrated on getting the body panels done.

Before bolting in the drivers side floor I added another support bar close to the transmission to keep the floor from flexing too much.

Next up was getting all the remaining vent lines hooked up and terminated. The transfer case and transmission vent lines run to a pair of valves, then to a filter.  If I roll I plan on closing the valves to prevent fluid loss during recovery. The engine vent line just runs to a filter while the fuel cell vent line has an inline tip over valve then terminates at a filter. 

My new master cylinder arrived on Thursday and I had the rear brakes bled in about 15 minutes so the problem definitely was the old master cylinder which I suspect never worked correctly even when new.

I spent Friday evening bolting on the last minute stuff like the skid plate and securing a few tools.  The test run was Saturday morning at 6am out at Table Mesa.

Right off the bat I noticed the buggy was running really hot when driving in high range on the roads.  Not sure if this is a new problem because I haven't really driven the buggy much during hot weather with the new V6.   Another issue is the rear suspension feels too stiff and the rig sits a bit high in the back. Some lighter springs will be needed to address both issues, I plan on swapping out the 250lb lower springs for some 200lb springs.  I am hoping it is not a valving issue as the new coilovers I bought were supposed to be valved from the factory the same as the old 16" travel coilovers.

As far as performance goes I am happy to say the rig performed the same or better than before.  I was able to crawl the big waterfall on Collateral Damage with no water in the front tires which was not possible with the old setup so that was an improvement.  The second real test was crawling the two big obstacles on Annihilator which the rig did with ease.


Lastly I am not real impressed with the PRP seats I installed in place of my old Beard seats.  They are just plain uncomfortable on the bumpy stuff. My best guess as to why they felt uncomfortable: I think the headrest is angled to far back, preventing you from resting your head on it while driving. In addition I felt like the cutouts for the shoulder belts was too low (I am 5' 10" tall), whenever I hit a bump it felt like my back was getting compressed which resulted in back pain after a few minutes of driving.  To fix the headrest issue I took the seat cover off and bent the frame to angle the headrest forward about 10 degrees.  The only thing I can do for the shoulder belt issue is route the shoulder belts beside the headrest. We'll see if they band-aid fixes will work, if not I'll be putting my old Beards back in and selling these to someone shorter than me.
