Jager Rods back in production...

Post  Straubtech on November 29th 2016, 12:11 pm

Jager will be back in production on aluminum connecting rods. Details:
Production will be 20 sets a month
First production run will be 6.535, 6.700, and 6.800 x 2.200 Journal and .990" pin
These will be ready to ship late January.

This is the rod the NHRA and IHRA outlawed. Can run engine just like you set clearances for steel rod engine.

Why were they outlawed in the first place?

Because one very well known engine builder and OEM sponsored team though a fit when they were discovered in the engine of who would end up being the 2004 NHRA Pro Stock Champion.

What i gathered from reading between the lines is Jager refused to pay to play with the brass of both NHRA and IHRA

Kirk is a racer. When he gives the community a better product that will outlast anything on the market, basically an aluminum rod with the life of a steel rod, he felt he was giving back to the racing community. When you can run all season on 1 set of rods at the level of Pro Stock, you have just saved that team 1000's of 1000's of dollars.

Chris,
I'm a little confused . NHRA doesn't have a restriction on what brands of rods can be used . For a rod to be banned it must not have met the material criteria in some way. I have heard great things about the rods and am glad to see they are going to be available again. NHRA did a similar ban on "metal matrix" pistons years ago citing expense and hazards involved in machining the material. It's OK to spend piles of money on a cylinder head lease program , but not on exotic material pistons/rods/etc. Go figure . Best of luck to Jager !

Kirk's rods were too light after they modified the rules

Kirk's rods were too light after they modified the rules

The rules were modified after they tore down a ProStock team's engine at Memphis after half a year of total dominance. What was found was green rods, confirmed, and a green crank, unconfirmed. The previous year I was present when we were introduced to every pro team in NHRA at the Bristol event. Only 1 team was responsive to the rods and they ordered and ran them for 2004.

Wonder what a 22Lb crank and 380 gram rods do to the acceleration of a 500CID prostock engine? I know in a 706CID BBF IHRA engine that when you replace a Ti rod with an aluminum rod that is 100 gms per rod lighter it shows about 30 average HP gain over the power curve but a significant ET drop.

For the crank? I have no idea really how much it would cost.

The return of the Jager rod is the stuff of Legend. It's been talked about for years, I hope it actually happens. Some were developed to run without a bearing

If you want to set the crank up not to run a bearing you can. The NHRA deal was needle bearing mains and rod on crank with an oil clearance of around .0004 to .0005". He is committed now with a renewed hope in this country. All of these will be manufactured on 100% USA made Haas CNC's.

I'm interested in learning about the engineering properties of this material,
unless it is proprietary and top secret.

Chris, does the material or alloy mix have a common name which can be researched ?

Kinda like how they made the factory big block Ford bore space illegal for some of the pro classes or how they outlawed the McGee quad cam head after guys were already using it etc etc etc.

He uses a Kaiser aluminum alloy made to his specs. The alloy is machined then transformed. He refers to the rod as Alumi

Probably near the same type aerospace material from which Wilfred at W.W. makes his rocker arms.

Don't know. Kirk's education is from the University of MI in Nuclear Propulsion.

Thanks Chris,
I was curious as to why NHRA implemented the weight rule on the rods but thought it was to combat titanium rods. No wonder the locals call Kirk a rocket scientist. It's true.

Kirk is no where near politically correct. Never will be. Those that know NHRA well know that it is a political game. Kirk looked at it like this....if a team spent $100K on rods a year now they would spend $10K for 3 sets. Saving the teams 10's of thousands. Why does he need to pay to have the part accepted.

It was also stated they were super secret squirrel stuff and nobody but 1 team had access to them. Well again I was at Bristol when we went to all the teams and introduced the rods to everyone. Only 1 team listened.

Could a lifter or lifter wheel be made out of it?

You're thinking what I'm thinking. Is the material hard enough to handle the abuse if machined into a lifter or a roller wheel?
