As a licensed PE Electrical Engineer crimp/compression connectors are the weakest type of connection and should be avoided when used in conditions where vibrations are present.

BUT a good crimp, which the installer should be able to do, in a tank with little to no air is pretty safe and no cause for concern.

I'm contemplating following suit !

Have you installed it yet ?

Yes i have. Haven't started it up yet though

Be careful filling! Haha. With the decreased size even with the little 1/8th vent tube still on there, if you fill with a can and not a normal fuel pump, the vent cant breath and it'll overflow! You have to have something get down far enough inside there. Everything else went smooth! No leaks seen! And with only 4.8 gallons in the tank my gauge reads 8 dots or half full!

Solder connection are the preferred way to go, No moister or vibration issues. Never had an issue with vibration on the track or on the water. What weakens the wire is when you strip away the insulation, No support. Shrink wrap will take care of that issue.

Car got dropped off at Moore Speed Performance who did my gas tank. Side exit exhaust to come!!

Did you ever finish the rear brake ducts and air jacks?

synolimit 11-17-2015 10:12 PM

Rear brake ducts are now mounted to the rear diff cooler. Everyone agreed cooling that was more important, even Doran. Im also thinking of doing two front 2" cooling ducts to keep them colder.

As for the air jacks ill be finishing soon. First the new exhaust. Once thats done we can do a flat bottem and rear diffusor. Once thats done i can mark and drill holes in the flat bottom where the legs will come through for the air jacks.

Coming along. Still need to box the frame in and finish.

Put a thin piece of polished stainless steel sheet metal over the area with the the exhaust sticking out about 1/8". Measuring from the exhaust pipe. 2" above, 2" in front, 2" below, and all the way to the edge of the fender. Think that would look good, plus it will keep the exhaust heat off of the paint, and be easier to clean. ;)

Ok all done!

So what we did was cut a 4" hole through the frame rail. As this will weaken the frame what Jon did was take a thick thick thick piece of SS sheet steel and roll it into a perfect tube and weld the seam. Then he remeved the wide body and side skirt and welded the 4" tube to both sides of the frame rail all around. On the inside he then used some plate steel to solidly strengthen that even more.

Next he built the CBE. First i used the Motordyne XYZ pipe that ends in 3". We used his V band clamp and welded that to the XYZ pipe and to a 18" long inline res. then it has 90ish degree bend to another inline res but this one instead of a bottle type is Vibrants ultra quiet straight through res. its really just a bigger oval res vs a smaller perfect circle res. then he used another flex coupler. Now i know the xyz pipe has 2 flex already but the reason he used a 3" flex right before it goes through the frame is because that section is solidly bolted to the frame rail. Reason he did that is we didnt want a 3" pipe banging inside a 4" pipe. The last bit of 3" pipe going through the frame through the 4" pipe has a 600 degree silicone coupler around it and DEI titanium wrap around it filling the 1/2" gap solidly. The exhaust tip if you will is solid and going no where!! Now to remove he used a band strap on the ultra quiet res to the flex coulper and of course remove the v band up front.

Thoughts?? Its amazing!! The craftsmanship is A+!! The sound is 100% different than what i had but its good! Loud loud loud on start up but quiet during idle. Highway sounded good with little to zero drone and rasp is zero! Its very very deep and throaty! On start up it reminded me of a exhaust cutout but not while driving.

Cant wait to be tuned!! Car had a lot deleted and all new cai, new injectors, fuel etc so no WOT yet! Tune to come!!

Looks seriously business from the outside, I like it. Hard to tell exactly what's going on underneath.. Could use some shots from further away. But I get the idea. Very cool. What fender flares are those?

I can jack it up and take some later. Its a moonbeam i bought used here.

That's what I was talking about with the polish sheet metal. Looks good. :tup:
