Camaro LT5

Mark, I was looking at the Dorman clutch master cylinder CM350014 on Summit's web page and they state that it is plastic, on page 11 yours is aluminum. Am I looking up the wrong one? Thanks

I’m excited about this should be very cool!

Cool is an understatement, but I don’t have a word to describe what I’m seeing with this build.

What size did you go with? I was wondering what type of gains should come from a 2.5 to 3” exhaust

Holley did some one off mufflers to knock down the sound pressure.

Manufacturers change their suppliers all the time. When I ordered it was aluminum. Maybe they changed it or the description is wrong. Dorman is most likely concerned with function.

This car is full 3 inch exhaust. Supercharger cars are less sensitive to exhaust back pressure than a N/A or turbo car. On Charlie’s Riv we did full 2.5. Not exactly sure how much power we lost if any when we did that. I have not had a chance to dyno a direct 2.5 vs 3. I do know these engine move around 1600 CFM of air at full power! My cars will put so much heat into the exhaust the pipes are almost purple to the tips. So it gets very hot and grows 3/4 of an inch.

I’m doing a 3 inch so the system will live on track.

The reason I’m going to bigger mufflers that the system on Gunner with a stock LT4 it would not meet the sound requirements at our local track Waterford. So bumping the power from 700ish to 900ish I’m sure I’ll need more sound control.

I’ll bet this car will not meet sound also. But they do not measure on practice days!

On a side note my neighbor could hear Jackass 2.0 on the highway at WOT 3 miles away. LOL. These cars are loud at WOT.

When I first built my car i wanted the noise. Now I want to quiet it down yet feed it more power. Debating on upgrading to a 3” if I can add more power but it has to be quiet. Another big problem of mine is how low my car is and I’m just thinking if I want to deal with the head ache for some small gains. On a sbe ls3 heartbeat setup my car made 707rwhp and 606tq using a stage 2 na cam.

Awesome. I love the small attention to detail that you're doing. It's the little things that add up and really make the car stand out.

Bumper looks great, far better fitment than stock for sure!

Love the slick integration of the front tow hook. Looks like it's a threaded boss and you can just remove it when not tracking it?

As always, thanks for sharing!

I saw the same thing on the Summit site when I was looking for my new master cylinder.

I looked it up on Amazon and it was described as having an aluminum body. Like Mark says, I think it is an error in the Summit description. However, I ordered mine from Amazon just in case.

Also, I had trouble finding 5/16" OD tubing here locally. I wound up ordering a piece of 316 stainless, 0.065" wall tubing 1' long from McMaster- Carr (PN 89495K405)

I've got all my parts on hand. Will swap out the pedals and master cylinder next week since we are in Covid 19 time out.

Hope this helps.

Thanks for the info Wes, I am calling the tech line at Dorman tomorrow to find out what they are now using for material on the master cylinder.

I purchased to Dorman part several months ago and it is aluminum.

The Wagner replacement part is made by AP, so in either case they are pretty good parts. Rockauto had both.

The Camaro has a 3" system exiting at a 45* angle backward just behind the rear tires. 17" Magnaflow mufflers is like stuffing 11# in a 10# hole. During idle and cruise it's quite nice but at WOT it makes all kinds of noise. With the Magnaflow being an absorbsion type it tends to get louder over time as the supercharger is tough on them.
