Homer's 1990 240 redblock exorcism

Just because. I've always wanted to use them on my own projects. I can, and I will.

You go Homer! Cool clamps BTW.

Sometimes one just wants to use the parts he wants to. Nothing wrong with that.

I am surprised you haven't painted them flat black though.;-)
 
Why buy it when you can make it yourself for cheaper?
Just some size mockups. I think the 6" is a winner, maybe 5"

How much is making them costing?
 
Kinda cool your making your own muffler! Can you tune it for drone free cruising?
 
You should make an adjustable muffler that's works like a slide whistle. How fun would that be pulling up? WHOOOOOOOOOOOOOOoooooooooooooooooooP!

I should be able to adjust the length pretty easily to do that.

Using two straight through/fiberglass packed mufflers will help also. I used 2 MagnaFlows, one in OEM resonator location, and OEM muffler location. Worked pretty well on my n/a.

Make the full exhaust all muffler so it will emit negative sound.

Maybe. I'm not going to "budget" for that right now though.

One muffler should be fine. It's going to have a metal core cat, a 5 cylinder, aluminum tubing and a turbo soooo pretty much nothing like your setup:-P

So got a chance to lay up the muffler housing this weekend. Also helped crank out some carbon parts for the formula team.
Quick rundown of the process
Prepreg cut. 4 layers.
Cytec 977-3 5 Harness

1 layer in. Used a scrap carbon tube lying around to roll it in. This is where it pays to take your time.

4th layer in.

Same goes for the air filter heat shield idea. Not sure if it will pan out.

Perf applied.

Bag in a bag, inception. It was a bit tricky but no leaks the first try.

Loaded into the autoclave, 6 hr cure with 1 hr ramp up and 1 hr ramp down. 350 F and 100 psi in the clave.

Got up early this morning and took the parts out. The thermal stresses broke all the tack welds but didnt spread the tube apart. Popped the seam apart and the tube slid right out as planned.
