Re: Reports on Burtz new engines
 

Thank you Dave - this is very helpful.

Do you have an idea of how much horsepower you're making with the Serr + 97?

Re: Reports on Burtz new engines
 

95hp at 2800 rpm.

Jim Brierley ground a cam for me that provided greater torque at a lower rpm.
I designed the car to pull a small camper and keeping the rpm in check was my goal.
Good Day!

Re: Reports on Burtz new engines
 

I’m building a 5 cam bearing Burtz and am considering a Serr head as well.. two things give me pause, one is the cost of horsepower, roughly 150 bucks per horse..the other is at the end of the day you’ve built a Pinto or Iron Duke for a whole lot more than you could buy one..

But hey the kids will be too busy spending my money to waste time lining my casket with it..

Re: Reports on Burtz new engines
 

I can't see how most tube headers are going to work as most are not turned length pipes to create the suction of having even flow pulses. Also, the low compression means there is not much energy available to do much. Low compression needs low restriction in the muffler. Too wide an exhaust pipe could lead to drain where exhaust doesn't flow fast enough. This seems to be forgotten in modern post turbo times.

It’s difficult to achieve extraction with a modified model A flathead engine exhaust system. Header doesn’t provide intake manifold heat beneficial to performance.

A header is sexy and the sound is unique..

The best combination is a stainless steel muffler that is ceramic coated. They offer many colors. Black would be good. I used the titanium color on my headers 3yrs. ago and
they still look great. If you get oil or some other stain on it you can brake clean and
scotch brite it off.

Dodge- who do you use for ceramic coating?

Re: Reports on Burtz new engines
 

I used a bake-on ceramic from a rattle can that I picked up in my local NAPA store, and it's holding up fine. It went from gray to a sort of gray-gold during curing in the oven (don't tell my co-pilot!) but has held steady color in use. Sorry I don't recall the name of it. I also got another can from one of the vendors, might have been from Snyders, and that's working fine as well.
