What's the verdict on the most reliable/cool kit for road course endurance ?
I think a modest amount of additional power is ok if it can be sustained.

I can't comment on Kraftwerks kits since there are none on track in Southern California that I know of, to test and collect data for. Jackson Racing, Vortech, and Innovate kits are abundant on track and are the only FI kits that are CARB legal right now. Vortech and Innovate had belt issues early on, but very few occurrences are found now due to proper revision of the system. JR has had no track failures thus far since its release. There was one occurrence in which the Rotrex SC blower failed, but Rotrex deemed it a manufacturing issue and has issued a warrantied blower free of charge.
For any FI system, you will need an engine oil cooler. Jackson Racing provides the one of the largest (if not largest), by volume, plug-and-play oil cooler kit on the market which has shown to maintain oil temperatures to a good level. Radiators are not absolutely necessary with SC, but fans are recommended with SC. With the Jackson Racing SC kit + Oil Cooler kit, we have found that the system maintains power even with 16 consecutive pulls on the dyno with the dyno fans on, hood closed, zero cooldown, zero ramping, etc. The back-to-back pulls
without the oil cooler kit showed massive drops in power with each pull. The turbo setup showed significant power loss after 3 pulls (% same as 11 pulls on the SC w/o oil cooler) with good cooling setup.
The Vortech guys are using oil cooler kits + aftermarket radiators + our recommended fan setup to keep things cool. It also helps to have a good vented hood to help draw out the heat.
With any FI kit, the proper preventative measures should be taken. @
King Tut has been able to provide information on how to develop a very reliable and powerful turbo setup. We have also made the Greddy Turbo Kit a success without overheating issues after some extensive cooling modifications. It's all in how much prep you put into the car as opposed to the absolute power gain you're looking for.
Hope all this information helps you out!
