Once again our engine platform has proven itself on the biggest stage in dirt car racing . Tyler qualified 6 th Friday night at the Dome in Group A . Started outside front row of the 3rd heat and finished a close 2 to one of the best in the business Johnathon Davenport locking us into the feature Friday night . Having to change transmission after the heat race we thought it was fixed and the other transmission we couldnt get it to stay in Direct without holding it in gear . Tyler started in 9 th but only run a couple laps then had to pull in the infield for a DNF . That put us behind the 8 ball for starting deep in our heat race Saturday and try to race our way into the big show Saturday . Started 5th in the 6th heat and Tyler drove the wheels off and finished in a transfer spot and made the race without even using a provisional . Started deep in the big show with the best in the country and he drove his way all the way up to 7 th and was coming fast when we broke the panardbar and tore out the driveshaft ending our night with about 12 laps to go . I think we had a solid top 3 car if it wasn’t for all our bad luck continuing this weekend .

Good ole number 7 made its 3rd time out a couple weeks ago at Eldora Speedway for the Steel block Class at the DTWC . The best steel blocks in the country was there and we finished a close 2 nd to Josh Rice in the Grand Finale . We won this race last year and our Engines are as good as any other big names out there . This car lapped up to 3 place a couple months ago at Skyline Speedway against the supers that weekend . So to sum it up it’s been out 3 times with two wins and a close second place finish . My phone rings all the time wondering about our very own 13 degree head that will be in production very soon . We got over 2 yrs working on them and feel they will be the best 13 degree head on the market with improved water cooling around the Sparkplug area and the very well designed raised port configuration on the market . The Jesel stands and valve cover rails were raised over .300 thousands to accommodate the super high intake port location . With over 410cfm of air flow these heads will stand strong against any other head on the market .

Isner Racing Engines dominates the hills of West Virginia as we won the Grand Reopening of WVMS this Saturday evening . Over 70 late models on hand for this awesome event as the thunder in the hills makes a major mark on racing history . Tyler Carpenter showed the way with his Isner Powered Kryptonite Racecar and took home the big check of the evening . So proud of this team who showed that this complete car including the engine was completely built within 20 miles of this racing facility . Our engine program is a family tradition which was started by my late father and racer the late Bob or to some Bobby Isner . His legacy will always be the trademark of Isner Racing Engines where his drive to built some of the best local engines on the market today and prove you don’t have to be the biggest to be the best . As my Dad and his best friend the late Bud Doll always told me growing up keep your head screwed on straight bud and you can compete with the best . This one is for both my Dad and Bud Doll for all their inspiration and words of pure wisdom .
