"After years of working on Z-Car engines trying to beat the F/GT record at Bonneville, I needed some rods for another attempt at putting an engine together. I was searching on the web for parts and came across the Rebello Racing page. I navigated around the site for about 15 minutes and then decided to call. I did get Dave on the phone and I think we talked for about 45 minutes. It was clear to me in that 45 minutes Dave was the guy that could make the Bonneville record a reality. I gave him my credit card number before we hung up and started planning to get him the intake manifold and carbs he agreed to use. THIS WAS THE BEST PHONE CALL I MADE! Dave and the guys at Rebello Racing really know what they are doing. I have found if you want to succeed in Racing, you need to rely on some experts in different areas. Rebello Racing is your source for the engines, hands down.

The first attempt came at the World Finals in 2009 where we came within .8MPH of breaking the record. We were really just learning what to do and if we had not had some fuel system problems we would have broken the record on our next run. June of 2010 we unloaded the car at East Coast Timing association and made 7 passes. Each one a new record. September 16-17 2010 at the World of Speed at the Bonneville Salt Flats the car Qualified and backed up the run to average 172.9 MPH. This broke a 25 year old Ferrari record. Quite a few people have tried to break this record over the years…….apparently none of them talked to Dave."

After much discussion with several possible engine builders, we decided to use Dave for three reasons: First, his currency with the latest technologies and approaches. Dave is not set in his ways and is constantly pushing himself to find new ways to make more power. Secondly, his use of computer modeling to “get us close” and many years of intuition to know when the model wasn't “getting it right” on something. Thirdly, his personality and general ability to work with others. He communicates well and is willing to explain and listen to ideas from non-experts and give them due consideration.

In the end our project was a huge success – a reliable engine that made target horsepower on the first attempt! We immediately caught up with everyone else in the class who were on their 4th and 5th engines and had done years of development. Dave immediately got it right on without trial and error.

Since this first engine has been completed, we have purchased 4 more engines from Dave and several cylinder heads to retrofit our older motors. In the classes we race in, no one has more power than our Rebello powered cars; we now have no excuses except the drivers…”

“I have been using Rebello race motors since 1994 starting with my 240z. Dave is truly one of the top experts on Zcar race preparation. When it comes to BMWs, he has had a lot of experience with the world challenge guys. He can build an in-line six engine like no one else. For me Dave has done some awesome work on my race motors. He does every thing I have asked for and more. He has always been a really fair guy to work with. He doesn’t hide anything and will tell you everything that is needed. He will usually tell you how much horsepower it will make and he works hard to get that result. Working with Dave is kind of like working with my dad. He is someone who will question me and help me achieve my ideas through his experience.” SIAS Tuning

“I started racing in 1992 with a Datsun 510 and Rebello built motors. We did fifteen to twenty races per year and I had a lot of GT4 wins. We pretty much dominated the class so the others had to race for second place. Dave always came through with a beautiful motor that had the most power. I never blew or holed a motor in all that time. One year I ran sixteen races on one engine before I took it apart and it looked like new. Dave truly made my racing years fun, we had a ball and it was some of the best times I had in my life.”
