Quincy Welding Speed Secrets Revealed
How many of you know that the very first Quincy stacks were made from my mom's brand new vacuum cleaner attachments?
Mom still tells me the story of how in the 1950's she finally saved up enough money to buy a brand new Kirby vacuum cleaner with all sorts of attachments, and dad came home at lunch with pipes on his mind. He saw mom's brand new chrome vacuum extension "pipes" and persuaded her to hand over the attachments so he could try them on his motor as tune pipes.
Well, she never got them back. Somebody out there may have the original Quincy Racing - Kirby pipes. I came across this picture of a Hurricane motor owned by Bob Dunlap, and this could very possibly be those 1st original Quincy pipes. That motor has got to be worth a fortune now if it is indeed the original one.
Now tell the truth, how many of you out there stole your mom's vacuum attachments to experiment with on your motors?
thanks,

More Quincy Welding Speed Secrets Revealed
Sometimes some of the best racing innovations come about by accident. 2 major Quincy Welding racing advances started out as flukes.
The 1st was water injection. We had an extremely porous aluminum cylinder casting on a Looper that significantly leaked water in the exhaust port area. It had phenomenal torque down low but couldn't seem to rev up. After discovering the leak by pressure testing the block, we knew we were on to something and started the process of developing water injection on the Loopers in the mid 1960s. Jerry Waldman won many championships using Quincy Welding's water injection systems.
The 2nd fluke was loose sleeve liners. We had 3 A engines that were dimensionally exactly alike. However, 1 consistently pulled significantly more horsepower on the dyno. That drove my father crazy for 2 or 3 years. We finally found out one day, when dad pressed the sleeves out, that the sleeves were barely making contact around the exhaust area or a major part of the cylinder. We then intentionally designed an experimental A with loose sleeves & it pulled more power. Quincy Welding then tried tighter sleeves on that engine and it then slowed down. This was quite a discovery. We're talking 3 to 5% difference in horsepower.
I might add, yes you can have sleeves that are too loose. Ideally, for our use, we ended up using a sleeve with 1/2 thousands interference and a large shoulder to secure it's stability. This area, I feel, has much yet to be discovered.
More coming, stay tuned.
