Naners makes a good point.

Up in the air if this is a good idea or not.

Yikes.

I would place the same liability warning on this parts as well.

 

FOR OFF ROAD-RACING USE ONLY

I can make those but have to get the correct tooling. 700$ approximate tool investment.

not much that I can tell. :D

 

I have been trying to put any money I can back into tooling and fixtures since I struck out on my own again.

don't try to be the first with something new. If it works on a john deere what would make a man with a sensible mind think it could work on a datsun.

Because it already exists for a L motor.

yeah i'm with Flatcat. This is not about inventing a new thing. Its about offering existing tech at a much lower price.

I'm confused as to why one would bag on innovation...

 

 

If you are refering to me giving my many,, many years of working in and around many sizes of roller chain type, bearing chain sprocket idler pulleys of every size conceivable ,, i'm not talking manure spreaders............ Well i ask you this,.... Why has no major auto manufacturer ( with their trillions of dollars in R&D and zillions of test miles)  use a bearing chain sprockets on their major timimg chains and opt for rubbing blocks??? Or even most motorcycles ever ,, on their main drive chain ,???

 

  Answer ,,, i already stated it in my earlier post.

 

 

Bagging would be me saying i don't like it with no prior experiance to back my statement up,,,,,,,,,,,, i was stating fact that i have seen in person and re-engineered stress points to alieve stress and slightly improve bearing life.   and just labeling something "off road only"  that is going to be a detriment to the running of a car if it suddenly fails,,,,,,,,,,,,, does not change the fact that I still think it is a bad idea to use one in your engine in my OPINION.

 

 

If your not talking about me,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, well there you go.

:rofl:

 

If Mattendew didn't want opinions he should have just made them,,  labeled them off road only,  and sold them,,  but he put this in discussions,,, so i gave my .03 cents      Do what you want .


So somehow while i was driving back from Eaglerock swap meet i somehow caused YOU to post this,,,, do really think members on this site are that stupid to believe i caused it??

http://community.rat...un-for-a-while/

Yeah i guess you do,,

 

BTW ,,,, the first person to call you a pussy,,,, ya might wanna check out his ethnicity ,, cuz i don't think it's what you think it is there snowflakeboy

 


..........................I shall call it, narclops.

Perhaps modify it with a friction bearing and an oil passage. *

I will say that bearing grades have a huge to do with failure

 

I agree with you Nanners, but some items are not meant for daily grind. Just because it is labeled for race use only doesn't mean its intent is to skirt quality or lack of proper engineering. It just means more attention to the motor on a daily or per engine use is needed. 

 

your assessment of the roller system being not in use may be a little off base. Most modern motors on the road now actually employ a roller or idler pulley for the Kevlar belts or chains for a timing system. Majority is a HTD Kevlar belt. But in those systems is a bearing or bearings that have the ability to withstand 40,000 RPM on a daily basis.

 

Can this be added to an L motor. By all means yes and would have durability to boot.

Usually friction slides have to be added due to angle tension and economics. far easier to produce a friction slide than a roller system. 

 

The bottom image is a motor that employs both a friction slide and a roller.

Here is  OS Giken with a an all bearings roller gear setup.

Not you man, sorry, I kinda wondered if I came across wierd. Cruznude seems to think being the first guy with a new idea is a bad thing. I thought that was odd.

So work is going to start on the 51mm ITB's this coming Monday. All fixtures have been designed and start milling them today. They have the provisions for the idle control valve. 

 

Any Investors?
