Re: Reports on Burtz new engines
JayJay,
Weber is a good option but buy some larger jets, mains and idle. The jets are easy to change. With the Weber on the Burtz block you can spin up past 3,000 rpm. I don't know how much rpm is possible. I have arbitrarily set my redline at 3,000 but do most of my cruising at 2,000. I tried the tube header and straight (open) exhaust but the stock exhaust manifold and Ares performance muffler is just as good and not nearly as noisy.

I have a Serr Miller head on mine and 18,500 miles of trouble free service. Great engine!

Re: Reports on Burtz new engines
@Dave in MN - what carb setup are you using?
Thanks! Raaf |

Re: Reports on Burtz new engines
I put the Aries High Performance muffler on my mostly stock A. I did have the cast iron header and the downdraft Holley/Webber carburetor. I noticed a loss of power. Hopefully it will do better on my RiLEY head engine.

Not to mention they could have put that ugly ass weld toward the middle of the car so you couldn't see it. Last edited by Y-Blockhead; 06-04-2023 at 08:01 PM. |

And you're right, that's certainly not the most attractive weld I've ever seen. JayJay

Re: Reports on Burtz new engines
The idea behind stainless isn't for looks. It is so they won't rust out.

Re: Reports on Burtz new engines
Aircraft have been using CRES type tubing since the WWII era. It turns brown over a fairly short period of time. It's certainly too much work to keep polished. The systems also need very good support due to the weight. They erode more than corrode but tend to crack when they get thin.
Model A cars already had issues with the exhaust manifold tending to slump down on the heavy end and a lot of that is due to the weight and arm of the exhaust pipe and muffler. Ford should have supported the pipe in front of the muffler as well as behind but they never considered it and issue. They likely didn't figure that so many of these cars would survive as long as they have, |

Re: Reports on Burtz new engines
I've seen it recommended to use the aftermarket sleeve that mates the tailpipe and the manifold, because supposedly it ensures that the tailpipe is oriented correctly and puts less stress on the joint.

Actually, I bought the stainless muffler because I didn't want it to rust out. I didn't like the polished look so it "buffed" it with a scotch-brite. But I didn't expect it to stain. now it looks terrible. |

Re: Reports on Burtz new engines
I am currently running one Stromberg 97. (Okay power)
I have also tried two Stromberg 81's (Very good power and throttle response...poor fuel economy, there is one throttle position where I cannot tune out a lean condition.) I have tried a Holley Sniper TBI Electronic fuel injection (Pretty good power and throttle response and great fuel efficiency) (SEE PHOTOS BELOW) I am planning a road trip to Alaska this summer and I will be using the Holley Sniper but carrying the single 97 as a backup. The manifold adapter directly below the Holley EFI is removed to install the single Stromberg 97. Good Day! Last edited by Dave in MN; 06-05-2023 at 09:25 PM. |

Re: Reports on Burtz new engines
If you had a Dodge block you could stick a Y head on it. |

Do you mind also telling me which manifold you are using for the single? ...and did you have to modify it to get it to fit since the plates where the bolts go are typically cut in half? (Yours appear to be modified in some way to account for this) I have an unbuilt Burtz and Serr head waiting for me to get my butt into gear but still sorting out some of the final details too. Thank you! Raaf |
