Goddamn. Tampa needs to get out of the 1990s and find out about KA motors and the research thats been done in the past year.
The pistons are good to 400hp. Ivan blew 3 motors at just over 400hp (ringlangs), so 7psi, 250hp, all bunk internet myth bullshit. 15psi.. maybe think about building up. But even TY has run that for 2 years, all stock. Then the rods. Ivan bent a rod at 30psi (25psi was 511rwhp). So that seems to be the limit for those.
Ivan, Daywalker, and Enjuku are all building for a 600+hp KA-T. There are numerous 300+ stock block KA-turbo motors running around, and more than a handful of built 400hp KA-Ts. For SR motors.. there are numerous 400+rwhp SR-powered 240s.
You all need to get with the times, if only to stop spreading rediculous internet myths and misinformation.
