I do wonder how the valve springs will handle high rpm with the stock cams. Of course, I have no idea how aggressive the ramp angles are. But generally speaking a 500rpm bump in rpm is safe on most engines. Of course, this is engineered this way by OEMs to help save the engine from new drivers that make mistakes shifting. This is purely a safety margin, but by utilizing the extra rpm at a "workable" range of RPM you are using up your cushion.

I remember reading here many months ago that people were being brave taking this car up to 9000rpm? How high was Visconti able to take this engine without catastrophe?

Is it possible to get a list of all known issues or install tips in the OP? It would be greatly appreciated for those interested in obtaining this kit. Thanks.

I can do that. So far no problems, just install notes on oil cooler reservoir and inter cooler piping clearances.

Excellent thanks so much. I think it will be very useful information. I'm really liking this kit. The stand alone belt drive and cleaner routing are big sellers.

I think the Rev limit had to stay at 7400 due to the rpm limit of the Rotrex at 100k. If you go to a smaller pulley you will be at that rpm limit even sooner ...

Good insight. Judging by the graph above there's little point in being above 7k.

I think the Stage 3 AVO fuel upgrade might be a nice addition with the higher boost pulley.
