"... I added a custom crank scraper fitted specifically to my crank/rod setup (I made the template and Kevin Johnson at crank-scrapers.com made one to my template) the DL1 data showed a 3-5 hp improvement at the wheels and 2-3 mph gain on the top end at Road Atlanta's back straight, with no other changes. And that was with WORSE air conditions (ambient temperature was higher, humidity was higher, and density was lower) when I went back to Road Atlanta after fitting the scraper. (March national vs. June national). This is on a full prep G-Production 1.5L Scirocco, making about 120 WHP at the time.

"I'm convinced.  If my competitors are dubious and not convinced, that's even better! I wish I had known about them when I raced ITC!"

[Mark was previously using the ABA windage tray alone --  seen here -- the gains he reported are above and beyond the use of that tray.]
