Thread: Gear Drive, Gear Misalignment

Tweet

One of the car rags did a test with the thumper cams and lost massive tq on the dyno,...exactly what comp says will not happen,I think the average was 60 ftlbs loss

Had a look at the site the names for those three cams is a bit tongue in cheek though....... thumper,,,,mutha thumper,,,,,,big mutha thumper. seem to sound mean but as shawnlee said, do they go as good as they sound ?

wow, you guys really got worked up over this one. I have had no problems with geardrives, but have had problems with "high quality" chains.

I have used Cloyes True roller chains with billet gears in any engine build that the engine would see over 6,000 rpms with ZERO FAILURE rate over the past 20 years.
I also have had a ZERO FAILURE rate when I have used the double roller set in "stocker type" rebuilds.
If you are breaking a chain that has a .250 pin along with the billet gears you are doing something wrong.
You do know that some of us do this for a living.
Some guys on this forum have been building engines for 40 years.

Haven't even worked in a machine shop since the late 70's, but when the good gears and chains came out the gear drives became just more leftover parts laying on a shelf in the parts room. I doubt anything has improved on gear drives other then there's a whole generation who now think the whine is kewl and harmful harmonics in an engine is just some geezer dream. For me, gear drives are a case of been there, done that, ain't goin' back. If you want your engine to whine like it has a blower then BUY A DANG BLOWER!!!!!!

Garlic? Wolfbane? A cross? Silver bullet? Will any of those resolve another thread-that-will-not-die?

Now where did I put my can of BS spray.
It has been a while since I have used it.
Did I ever tell you guys about the "72" Winter Nationals??

No, that was the year my "trike" ran 9.40's.
Of couse I was only four at the time.
I was also the jr. crew chief for Donny Garlits that year.

The gov. is trying to control the manufacturing of BS spray.

Hey, now there's a new marketing pattern!!!!! Start selling blowers for "the same sound as a gear drive"!!!!!! The "whiney sound" guys should just jump all over that thing!!!!!!

How do I make sure the drive-in crowd hears my lumpy cam over the sound of my gear drive whine? Is there some sort of adjustable muffler available?
