Texas ProKart Challenge TaG Senior and TaG Master racers please note the following tech bulletin from John Motley the SKUSA National Technical Director

IAME X30 Engine

April 2nd, 2014

We have been evaluating this engine for some time. In addition to conducting our own independent research,   we have been following the experience of other series.

Here are our findings – as well as our current plans – for this engine in SKUSA competition, as of today April 2, 2014:

  • While it is similar in performance to the existing Leopard and Leopard 09, its characteristics do favor some track configurations.
  • The crankshaft redesign and balancer shaft significantly improve reliability.
  • Lower rev limiter adds to improved reliability and lengthens rebuild time.

This engine has been approved for SKUSA competition effective June 1, 2014, for the TaG Senior and TaG Master classes only.At this time it is our intent to have the TaG Junior class remain a Leopard-only class through 2015. This helps provide a market to sell existing Leopard engines for Senior or Master drivers who want to switch to the X30. Initially the X30 engine will have a minimum weight 20 lbs. above the Leopard weights – thus the X30 will be at 375 lbs for TaG Senior and  405 lbs for TaG Master.

Please keep in mind that the SKUSA rules allow us to adjust weights at any time to balance competition.

Complete technical specifications will posted on the SKUSA website soon.
