Camaro LT5

Some updates. I’ve never done this but Alex tucked and smithed the rear bumper. Looks great. The car was missing the rear bumper so we purchased a repo and fixed it.

Because the LT5 needs 2 intercooler pumps we needed to sort out the plumbing. The plan was always two 3/4 inch lines teed into a one inch line. To clean up the plumping we hard lined a lot of the one in lines. This required some 3/4 to 1 inch Y fittings. When you can’t find what you want make it.

Because a lot of track events want tow hooks we integrated one into the front bumper bracket.

We put the car on the ground to check tire clearances. Everyone always asks me about wheel widths and backspacing. It takes a lot of work and finesse to get a good tire wheel package. Every car is a little different and they are all tweeted to fit.

Up next week is exhaust. Because Holley make a kit now hopefully it will go quick. But like everything on these car I wanted to modify the “off the shelf” system.

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

Man, everything looks so good. But, that's nothing new here. Once we see you start a new build Mark...we all know we're in for a treat. I like how you're adding a few custom touches on this one.

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

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.

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

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.
