Introducing ULTRA STROKER pistons from Wiseco designed by engine builders with 20 plus years in the industry
One of the definitive ways to get more power from your Banshee is by increasing the stroke of the engine.
This is a pair of BRAND NEW Wiseco forged ULTRA STROKER pistons.
These pistons are custom made by Wiseco (part number 11882)
They allow you to run a 4mm stroke long rod crank (58mm stroke 115mm rod) ?
The stock banshee head will require a .060? base gasket to work properly. We also offer the .060? base gasket as well.
Availability is 64.00, 64.50, 65.00, 65.50, and 66.00mm sizes for your cylinders
These are Wiseco forged pistons that takes all the good features to make much more power than Blaster pistons:
- The piston domes are 13 degrees - so you can run a stock banshee head (must use the .060 base gasket)
- a Blaster 573 piston has 9 degrees, so the squish is not optimal when using a stock Banshee head.
- 6mm pin offset location - compensated for the increased stroke and rod length
1. The raised intake windows allow the piston windows to be fully open at BDC. (Unlike the blaster piston, in which they are mostly closed at BDC) - Please see the last auction photo for a visual between an ULTRA piston (left) and a BLASTER piston (right)
Why use ULTRA STROKER PISTONS?
You have a stock bore banshee, and you don't want to bore it .080?over to the last bore just to run Blaster pistons (Blasters are 66.00mm or larger)
You don'thave to re-cut 9 degree Blaster dome for your Cool Head or re-cut your stock head (we also sell 13 degree ultra stroker domes that are bolt on - the only modification with a Pro Design Cool Head is our custom CNC cut dome and using a .020? base gasket instead)
You don't want to run a spacer plate, the transfer timing will be out of specifications, above 135 crank angle degree.
