I live only an hour or so away from the Olthoff shop, and am able to drive up and visit often. Dennis is a very, very busy man. He is immensely knowledgable about all things SPF, and has experience with powerplants from many sources. Just be sure that when you call for advice, you have your questions and thoughts concise and specific, because he doesn't have much time for long casual conversations and discussions. I have the utmost respect for the service and and advice i have gotten from Olthoff Racing over the past 8 years.

all the best....
