You don't have to raise the RPM limit to experience a failure. we have redesigned the gear tooth to increase performance and strength as well as changed the contact points with the crank to prevent microwelding. This will give you a bulletproof product under stock conditions and is rated up to 10k rpms. All gears are certified and come with their own blueprint documentation.

Surprising that there have been so many failing pumps at stock revs and so few miles, but no one seems to be posting about them. I know not everyone who owns a Z is on here but you'd think the people that autocross regularly or track would have posted issues with the stock limiter. The only posts on here with failures have been those with up'd rev limiters.

As you stated not everyone posts about their failures. the unit we posted with a broken pump is a forum member here, but chose not to post for whatever reason. In respect to his privacy we will not disclose his username unless he feels comfortable chiming in. A lot of people dont see it as a problem until the gears break on them and then its like how the hell did this happen? not all the posts here of broken gears are of raised RPM limits...

Again micro-welding can and has happened under stock normal loads, this is a fact.

We have seen it first hand and so have several other shops. Several shops have seen it as a great product and will be carrying these items here in the next few weeks for their customers.
