K1 rods are back in stock, and all back orders are being fulfilled. Anyone else who needs a set, I recommend getting them now because supply is limited.

Also our pistons are back in stock too!!!

 

Would be a great belated Christmas gift! Or even a great way to kick off 2008!

 

 

Any chance of listing the specs on the rods and pistons. Like what RPMs can they withstand, HP, tQ, etc... How are they in comparison to other rods/pistons?

 

hp/tq is just a guess... it all depends on the rest of the setup... I believe etsnet has them and ScionGT35R has them, and 35R hit close to 500 before the nut on the oil pump fell off and got sucked up into the pickup tube... I am sure they can withstand plenty of abuse...

You can not put a rating to pistons and rods because tuning and use of the car will dictate the strength and longevity of the rods and such.

 

Just put an outragous number behind them. He'll buy them then

 

lmao syldrin ^^

 

When inquiring about other Pistons, the manufactures have given rough estimates of their max reving potential. I was also more or less seeking information on the thickness of the rods compared to others. Materials differences, etc..

 

Not true. Please show me one manufacturer that lists power rating for their rods!

It is a steel billet connecting rod in a H-beam format, which can clearly be seen from the picture I posted above.

 

So, you mean to tell me that manufactures don't test their own products? Example, if you ask, they will give you an example of a car that is using their products and the specs/conditions they are using them in.....(i.e. A Supra reving to 10krpm's using their specific set of rods/pistons/bearings...whatever, that you were inquiring about).

 

E-dubb is correct. I have NEVER seen one rod manufacturer: Eagle, Crower, Oilver, Carrillo, GReddy, K1 etc EVER put a HP rating on a connecting rod. These K1s have been put into several builds and have yielded some excellent results including ScionGT35R in PR.

 

Do you have other examples? ScionGT35R I understand is having motor issues, so he is not running presently. Are there any cars running right now using these rods/pistons?

 

I think they do, but with something like a connecting rod, there are soooo many external factors that could destroy the composition of the rods quickly. Including and not limited to: track abuse, fuel used, tuning etc...

Here are some crucial quotes from K1's site directly, which should eliminate any other questions:

"Billet 4340 Steel H Beam connecting rods. Closely monitored material mechanical properties for optimum performance. Designed and finish honed in the USA. Sizes held to some of the tightest tolerances in the industry, +/- .0001” and +/- 1 gram per end. Shot peened for improved fatigue life. Bronze wrist pin bushings. Exclusively using ARP 2000 fasteners."

"It is nearly impossible to put a power rating on a connecting rod. Power is
produced from the expanding gasses in the combustion chamber pushing
down on the piston which in turn pushes down on the connecting rods.
While there are certain situations that could lead to failed rods due to compressive
loads, rods generally don’t fail because of power loads. If rods broke
due to power, they would experience severe bending to the point of permanent
deformation prior to breaking. When you see a broken connecting rod
where there is no seizure of the bearing or failure of the piston/pin/cylinder
wall, look closely and you will see that the rod was actually pulled in two.
This high tension pulling load on the rod takes place at TDC on the exhaust
stroke and is caused by the piston trying to continue up the cylinder walls
and through the cylinder head and the crankshaft trying to pull it back
down. The heavier the piston, longer the stroke and the higher the RPM, the
more pulling load is placed on the rod. When you look at a dyno sheet, you
will see that as the RPM is taken past peak power the power falls off. However,
most of us have seen engines that have had rods break when over revved.
If power broke rods, they would never break due to being over revved."

 

Jeff's car ran our pistons, and so have several other people. However, Jeff did not run these rods because they came out after his build was done.

 

I've only ever really seen pistons rated not rods.

 

I haz t3h pictorzzzzz

 

oh schnaps! The stock tC rod and piston off the wall of shame.

 

Double-u Tee Eff,. That r0d got pwn3d
