Re: Supercharging a Model A
jeepguy1948,
The sniper setup requires a return line from the injector to the gas tank. Some have suggested just putting a tee in the feed to the fuel pump instead of going back to the tank. It seems like that would work but I was worried it would mess up the feed and return pressures for the fuel pump and injector. I am still tempted. As far as the Weber, most people running them, love them. I was never happy with its performance but it could be me and not the carb. |

Re: Supercharging a Model A
When you were running the Stromberg did you have some type of heat on the intake (I assume that you were also running a header and couldn’t bolt the 2 manifolds together as in the stock configuration)? It stands to reason that heat for the intake would be beneficial since Ford provided for it. I have heard of fuel puddling issues in the intake when the Stromberg is used without heat. I have also seen pictures of a device that was installed between the carb and the manifold which uses coolant hot water for heat. Thoughts? PS; I actually have a Webber and intake but tuning the darn things appears intimidating to me, I would think one would need to plumb in a air/fuel sensor in the exhaust to determine exactly what is going on with it.

Re: Supercharging a Model A
It would be interesting to see what could be done with adapting a supercharger on a Burtz engine. This engine design has many of the negatives of the stock A engine removed, i.e. 5mains, balanced weighted crank, pressurized lubrication, etc,. It seems this design would be a much better starting point when compared to the stock engine.

Re: Supercharging a Model A
Gene, try a Murray Horn harmonic balancer, all steel design. Works as it should, reduces the reason pulleys break in the first place.
Flathead compression above 7 to one begins to reduce air flow, turbocharging has no parasitic load like a supercharger does..Kubota compact construction uses turbos that almost perfectly match the A engine. The model A 3 main bearings have adequate area to handle the increased load, babbit issues with compression is an old wives tale.. you can have head gasket issues, running a hig aggregate compression by boost and head design can exceed the gaskets ability for a long life. |

She’s a hoot to drive, you get to roll on that model a torque from 5 to 50 mph splitting second. Use a modern style head gasket..it take the joy of driving a stock A and doubles it.. |

Re: Supercharging a Model A
Does the Murray Horn harmonic balancer differ from the one made in New Zeeland?

Re: Supercharging a Model A
That is the one from NZ. Nice pulleys.

Re: Supercharging a Model A
Thanks, good to know. I have been seriously considering one but haven’t pulled the trigger yet. See a like a lot of money for something so simple but a lot of people like them so they must be worth it.

Re: Supercharging a Model A
Jack Backer,
Murry seems to have stopped listing on EBAY and did not reply to an email that I sent. This was a couple months ago if you have any newer information, please let me know. I would ideally like to run a serpentine with the harmonic. I just got 3 serpentine pulleys from Cling's in Arizona (2 small pulleys and 1 crank pulley). My intention is to remount the supercharger with the serpentine setup with the idea that it will require less belt tension to run the supercharger. I intend to use a tensioner instead of tightening the heck out of the belt. Depending where I mount the tensioner, it will provide more wrap around the alternator and supercharger pulleys to reduce slip without high preloads (or so I hope). The serpentine belt will also reduce the mass of the belt and the whipping that goes along with it. If this doesn't do it, I am going to a V8. |

I originally intended to do exactly that. Since I already have a rebuilt original engine, I had to go with it. At the time, the date for the Burtz kept moving out. I think it would be a great combo but I can't just throw money at my ideal setup. Besides, as fantastic as the Burtz engine coming to market is, it is still made in China. As my son said, would you rather go to a Chevy V8 or a Chinese made engine? I think I will eventually go with a Ford V8. |

Re: Supercharging a Model A
Sometimes I think a small block Ford would be a H**L of a lot easier than the extremes we go to to get a little more power. Also, I have a feeling that before too long we may not be getting imports from China, there is no question they are not nice people and I have to believe that sooner or later the US will catch on. I know that Burtz tried for years to get a domestic foundry to work with him but no go so he really had no choice

Re: Supercharging a Model A
I bought mine from Murray a few years ago, great guy to do business with. A harmonic balancer pays for itself if you run a stock A crank, harmonic distortion is what takes out the center main bearing..the balancer dissipates the vibration some.
One nice thing about the serpentine is it handles a lot more load than a V belt..they transmit power better too, dont run as hot. clings is another first class outfit to deal with.. word is their doors are closing too |

Re: Supercharging a Model A
The Chinese are fine properly funded.. it’s when someone tries to squeeze every dime out of working with them that the quality suffers. It’s your car, do as you wish..I prefer 200 cuin L head.. it’s a stumpy little motor..

Re: Supercharging a Model A
You freaked me out, man. I called Cling's first thing this morning. He is not closing his doors, but he says he would sell the business to someone who met his asking price.

Re: Supercharging a Model A
I’ll see if I can’t get ahold of Dave Gerold but his motor with the OHV will probably flow a lot more air and a lot more HP then my stock-ish banger so will push it into the range in which the Sniper was designed for.
