A little project update on Chug A Lug

Well of course its pissing down rain since I have a full weekend off (maybe even Monday) So yesterday I did some jet swapping and found a little more power and closer Air Fuel Ratio numbers. We went on a very scenic drive to a small country inn about 14 miles from home I chose a bunch of gravel roads with some steep hills to see how CHUG was running with the new jets. Did very well.

So today I decided to go completely through the tuning steps on the Weber. I found the float was not anywhere near where it should be, fixed that. I dropped down to the next size small Main Jets and dropped a couple sizes on the Air Correction Jets (based on a talk with 52 M38 and his experience with the Weber DGV) I took one very wet test drive and came back to do some fiddling around with the adjustment screws but no Jet changes. It shows its running a big Lean at Idle right now. I want to run it for a while again before I change anything.

If it rains tomorrow (Monday) they are talking about calling off work so I might be able to in between showers get in a couple test runs.

Going to fix the Air Compressor electrical supply line problem I developed while down at Mikes at the Spring Fling. Should just be a matter of making up a new 1" #12 wire with a couple terminal lugs on it. That was where the juice stopped when I tested it on the trail.

I got the leading edge of the Top riveted together Sat morning. But I can't do anything with it cause I would need to reassemble the top on the tub to take the next steps and that would anchor CHUG in place until I take it back off and its a 2 man job.

OH and I learned a valuable lesson at dinner the other night. DO NOT LEAVE TO GO OUT TO TALK TO THE GUYS LOOKING AT YOUR JEEP DURING DINNER. She was not amused LOL. Had to buy her a second glass of wine just to make her smile. And since I was reminded of my mistake as we entered the house at the end of the evening I guess I best take note.

OK the Dyno tune is scheduled and so is my first real car show of the year (who knows maybe my only car show of the year) It will be on the 4th hoping the 15 year old grand daughter can go with (gotta ask DAD) Its about 55 miles away so that should be about right. She's only ever been around town here.

Me and the Mrs. (Ok so selfies are really not my thing)

And the little lunch cooler

Its made from composite sign board (2 layers of .020" aluminum with about a .090 layer of composite) and some .062 x 3/4" aluminum angle and a zillon pop rivets. The hinge is Stainless from my junk pile so of course the paint barely sticks to it. The insulation is 1" thick Owens Corning Pink foam board R5 same as I am using for the hard top. No drain going to try to keep the Ice contained. it gives me a nice place to store the Seatbelt cushion I use to cushion the hood when I open it to help keep down rub marks. Thats the fuzzy black thing. And once I have the wood strips on the floor I will make a more secure way to anchor it against the console.

 Dan J & I put my 1993 22RE Toyota 4x4 on that dyno back in the day. 110hp!, proudly the lowest hp vehicle he had on the dyno to that point. 

OK I downloaded an app called Drag Racer from the Google Play Store free with some ads.

I went out on the arrow straight and almost level Hwy 214 just north of my house and made a first run at 0-60mph Chug was just barely warmed up the air temp was about 60-61 degrees F no wind.

results with 100% GPS accuracy

10mph     0.9sec   @ 9ft

20mph     4.1sec   @89ft

30mph     7.6sec   @223ft

40mph   12.5sec   @480ft

50mph   19.4sec   @937ft

60mph   42.0sec   @2753ft

1/8th mile = 15.4sec  @44mph

1/4 mile    = 24.5sec  @52mph

So those are my base lines to tune against.

A fun comparison the 1968 Wagoneer with the 6cyl 3spd did 0-60 in 14.2sec and the 1/4 mile in 19.9sec at 68 mph

So if anyone wants a way to compare their Willys to CHUG this would be a way.

3,100 seems heavy for a flat fender.

Did you weigh it?

So as I have no time to work on CHUG or the hard top project due to 55hr plus weeks at work I thought I would start buying up materials for finishing the hard top so today I ordered a sheet of 6061 1/8" x 24 x 48 Aluminum that will become the bottom half of the doors. Found some open box grade stuff on eBay for $97 with shipping so that's on its way. Pretty close to the last thing I will need until I order locally the 1/4" scratch resistant Polycarbonate for the windows.

We have a TAP Plastic's place about 40 min North of here that carries it in stock. So I will once the metal of the top is done make some patterns and have them cut it for me. Lot less stress that way. it might not break like glass but it can still be cut the wrong size or scratched so let them worry about that.

If I do get a chance to work on CHUG #1 on the list is to finally figure out the OD not wanting to stay in direct. That should make a huge difference in driving it.

#2 is to work on timing and the timing curve to try to squeeze the horses. I'll also be putting on the big Fresh Air Intake system. That should make a little difference on the hwy.

Not sure if you had seen this. I stumbled across it a while back when searching for an aluminum head. Maybe it gives you something to compare.

A little history on HP measurements.
