My local diesel shop,Imler diesel had dyno day Saturday. I was able to get a feel for my Ramifier numbers. I made three runs,one stock,one with Ramifier,and one 1/4 mile simulation. The stock California S. O. made 183/352. Then with the Ramifier 275/612 for an increase of 93/261. The 1/4 mile was 16. 3. This was on a mustang dyno,about 2:30 in the afternoon,about 83 degrees,i think i would see a bit higher numbers if i ran early a. m. (cooler air). All in all i am happy. I also saw a '03 run with the Banks six gun-speed loader and he was not a happy camper.
