New engine build

Wouldn't fooling the engine that it was colder than actual make the mixture richer? In any case, I've found that this cam likes to idle a bit higher before it cleans up. I found this when trying to get through DEQ that if I set the idle to about ~1300rpm the emissions went to almost nothing whereas when it was set to the correct ~1000 it was stinky rich and wouldn't pass. This was all before setting the mixture with the LM1 one also so that could have been a factor.

Sounds wild:)

It was designed and built by Chris Foley of Tangerine Racing for Jake to sell in his store.

You need to back the wiper towards lean and possibly release the black cog a few teeth. That will keep your 1,300 sufficient, and give you a cleaner idle.

I seen'd the muffler with my own eyes the other day. It is a bit loud, like some sort of military transport. We could hear ya comin on the freeway. Also, it does stick out towards the back too far, you gotta watch that some drunken stumpy camp trip (which is what did in my previous bumper, a stump in the Coast Range, Turk was there believe it or not before he signed up to the Galactic Empire)
But I'll bet it breathes really well for that very special (Church Lady) engine ya got back there.
So are you finally dialed in and happy? Hopefully it will be a very productive camp season this year since you an yer gal have settled in somewhat.

Yeah, it does stick out further than I'd like. Really wish it tucked up under the bumper better but to get those pipes the right length they have to go somewhere. It's not the first time I've had a muffler that hangs out in the open so I've become very aware of where I'm backing up or into. First one I had a few years ago took on some logs and rocks on more than one occasion.

I kind of like the sound personally. The reason you heard me coming is because I was on the throttle up that hill. When I'm just cruising it's not bad at all. In any case it's made enough of a positive difference in drivability that I'll accept all of the negatives.

I took some driving videos last night for people that are interested in it to get a sense of the tone and volume of the header. Inside the bus it's really not too bad.

I like it, the pic you took at first was at an angle. In person I think it looks fine. How often do you oogle yer muffler anywho?

The sound is awesome, very throaty.

I think it sounds great. Aggressive, throaty, authoratative.

there are factory bus engines with a hole in the plate. i can provide the part number if you like, so no throttle plates are harmed.

For whatever it's worth, when I was replacing the throttle body seal this morning, I noticed that the throttle plate I've got has the hole in it. TB came from a California-spec '81 Vanagon .. if it matters. The junker TB out in the garage came from a '76 and has no hole.

(yes, junker. Shaft is bent at the cable arm)

Ah!@ I was just talking to Scott about this but he didn't have any in stock. He said he thought the hole was 3/32 but didn't recall exactly where the hole was other than it was on the leading edge of the plate. Did you happen to notice?

Didn't exactly notice, other than on the rearwards side of the butterfly (front is front). 3/32 seems a bit smaller than what I remember seeing too...

I'll check it out tomorrow afternoon, need to replace the barrel clamp for the throttle cable. The threads are stripped and it's not holding tight, cable kept slipping when I was out running errands this evening.

Didn't get a picture, but it looks to be about halfway between the shaft and edge of the butterfly in that direction, and slightly off-center towards the top of the TB bore. My 3/32 drill bit fit through but 1/8 didn't so .. that's about the right size.

I've got a spare un-drilled butterfly in the junker TB if you wind up needing it...

Thanks, I've got a spare throttle body that I can try this on.

Haven't tried it yet. Just been driving it.
