Yeah I know I looked at a '83 Camaro today for SCCA A-Sedan. Still a $1000 pile needs $20K to win anything, plus I have to spend $5K more on driving school. Done some but not enough to be happy with it. Then I just end up racing a 305 with stock heads and 380hp, what fun is that?

Why is racing so dam expensive?

Aftermarket Con Rod

Car racing products firm offers powder-forged (P/F) connecting rods next year.

Howards Cams & Racing Components (HCR), Oshkosh, WI, will sell high-performance P/F con rods made by GKN Sinter Metals, Auburn Hills, MI. The rods should be available for aftermarket sales by the end of the first quarter of 2004. The first design will be a small-block Chevrolet 6.0-inch rod, which can be expanded to other applications. HCR sells to enthusiasts in oval racing, drag racing, and tractor pulling, as well as to owners of street rods and off-road vehicles. GKN is also eyeing marine, industrial, and endurance applications. HCR expects to market the rods in a set, retailing for about $600.
Not bad I suppose, especially considering the weight of the rods... but Pro Mods sound like a better option at this stage of the game (cost wise). If the cost's a bit lower and the weight looks real good I may pick up a a set next year in the engine build... but as it is they need to produce some big numbers if they want more support. It's not a question of "if it works as well", but whether "it works better" for the same price. No point in going with an equal product if others have the same claims AND a track record to back it up. Just personal risk-analysis really.

As I said "Problem is customer acceptance."


Actually leads to this.....


As a customer do you care how well the motor performs and lasts or do you really give a rats *** about every little part in the thing? I'm betting that Sonny Lenord and Jon Kaase don't tell you dick about the motor that goes in the IHRA Pro Stock cars that run them other than Yeah it's a Chevy/Ford and it's 810 cubes.

Bret,
Is GM running the PP rods in the C5R yet?

If you bring your checkbook when you talk to John to pick up your engine,he will tell you all about it.

yeah, what they need to do is start some name-dropping by cut-rate supplies to tuners that can get their stuff in mainstream media like Car&Driver and such. Wouldn't hurt to sponser the Engine Master's Challenge or some sprint-car teams.

They'd get some crazy attention if they earned some "street cred" right out of the gate.

Of course this comes down to finding racers and engine builders open to such a new technology (or at least new in a high-performance application ).

Probably a Carrillo, Arrow or Oliver rod would be my guess since it's a low volume race motor. That's the key most likely is the volume of something like that. Howard's can only afford to do this in the 6.0" size and not all the other bastard sizes.

Pretty true.

Even then look at beehive springs, Comp has more articles on those things and what do you get, nothing but people questioning those things. Believe me I hear it all the time.

yeah I suppose that's the case. Depends if your a prefessional team, how open the builder is in about the parts used, etc...

Only problem is, until someone uses them openly, the stigma will remain that "forged is second only to billet" (and that's debatable as well).

True because the best case is a vacuum forging that is fully machined (over 1/8inch taken off everywhere) al la a Arrow.

Aren't Con Rods FUN!

What still impresses me is the busted rod table at Oliver during PRI. Those things look like abstract art, and you wonder how guys break them, or bend them.

When the General puts them in their showpiece race cars and proves them I will probably take another look.
Just to much money involved in a good build these days to go with other than what you know will get the job done.

I'm wondering if they are able to do this with the compressed graphite blocks that I've heard about?

"Compressed graphite"

Ever broke a pencil lead? Hell, I have to resort to a Big Chief just to keep them alive.

Dunno, but I think graphite would be a little too brittle to make a good connecting rod. I aint no materials guy though.

WRT Customer acceptance, time will tell. They have thier cash cow with the OEM, so they have plenty of time to get their product in the hands of performance engine builders. I have been very content to sit back and watch people try new things. Just a hobby for me so I have that luxury.

On that note... has anyone else noticed that Howards is actually advertising now? I think those boys finally woke up and smelled the money cause they are actually putting advertisements in the magazines now.
You mention Howards to anyone two years ago and they'd just ask, "Who's that?". Good for them, they have a great line of products... secret's gonna be out of the bag now.

The other thing that is really impressive about the design on the PPF rods is the Finite Element Analysis. Only rods that I know of that have this are $1200 Oliver Billets. One reason why the rods are so strong for the mass is the design. I’ve seen some studies on H beams vs. I beams like Oliver’s and the shape is one reason they are so dam good.
Lunati/Holley uses Pro-Engineer along with Pro-E's ad-in Pro-Mechanical for FEA. Pro-E is one of the largest, if not the most widely used CAD software manufacturer out there. I would actually be very surprised to find that Manley, Pauter and other rod manufacturers aren't using a CAD system for rod design, along with the ad-in FEA tools that come with them.

Everyone's going to 3d CAD modeling these days. Just streamlines the manufacturing process, especially when you can keep it all under one roof.

Bret said he thought it'd be a good idea to use the cracked cap technique on the main journals, and I was wondering if that might be done on the blocks made of compressed graphite. For a part that doesn't move and just holds bearings, it might work very well. I wasn't talking about making rods out of that stuff.

That's not going to happen, because you can't just make a custom PM rod, it's like making a custom plastic intake like a LS1 intake, it's done for high quality, high volume production not for 10 motors a year. To me a 450rwhp-500rwhp LS1 that turns 6700-6800rpm is pretty good proof of the OEM PM rod straight of the assembly line. The aftermarket PM rods are a better quality material and better quality piece.

I suspsect that Howard's has put a ton of money into this project so I would expect that they did it the right way or it's going to be a big bust financially.
