NHRS kits
Which would, in your humble opinions, be the better of the two 1250 kits?
The Axtell Cast Iron Cylinders or the Iron Lined Aluminum Cylinders? |

The cast iron Axtell cylinders are extremely stiff and will not distort. This is a much better option.

Neither is a bad choice but if have a heavy hand on the throttle my vote is for Axtell ..

How would the Axtell hold up in Florida heat? I know that the current setup on my Evo engine has it over 300 degrees right now. Would I run into heat issues with the cast irons?

That's what is being reported from the ECU on a Dakota Digital. I'm not sure where it picks it up from, but it's not from the oil tank. |
Your heads and juggs can easily hit 350º+ during normal operating temps.
The aluminum juggs would be fine for Florida. |
Call the guys at NHRS and tell them how you ride. If you ride your bike hard like most sportster owners do then they will tell you to go with the Axtell. How you ride is much more of a factor than you living Florida.

Aluminum: 5lbs (each) lighter with better cooling. Iron: more rigid (less flexing/warping) with better ring seal. 1200/1250 Use the aluminum 88" or 90" may want to consider iron. When you bore the cases for the larger cyls, it gets quite thin. So having a solid cylinder gives it a little more strength. Here is a quote from Dan @ NRHS: Our new NRHS iron lined 1250 cylinder have an incredibly thick liner which is almost as stiff as a full cast iron cylinder yet saves about 5 lbs each cylinder and has better heat dissipation. The liners on these are as thick as a stock 883 cylinder to give you an idea. These are what I recommend for a street ridden bike now. |
