Small restrictor, in a truck, 10 should be no problem. Im running the 5.6mm on my P5 and come at 10-10:30 with time to spare... Buggy, may be close. May have to add an exhaust cooler and run a longer feed line.

The difference between the Clio and P5XLT are the cooling head and carb. So if the carb is supposed to be that much better, you got even more time to spare..

I hear Murnan does good work. Get in contact with him and find out what he is seeing from his motors. Straight from the horses mouth is always a good thing. Its the back side you have to worry about.
