Marine EZ-EFI / Edelbrock Pro-Flo XT Tunnel Ram installation

Saturday, September 25th, 2010

MR Marine in Spring Lake, MI uses our EZ-EFI tunnel ram kits to convert twin big block chevy mercruiser engines to fuel injection.  According to Mark, the install was straightfoward and trouble free.  (it looks to me as if you’d have to stand on your head for a few hours, but Mark doesn’t seem to mind) Setup and tuning was straightforward and very effective. Start up was immediate. Our kits use Edelbrock Pro-Flow tunnel rams and throttle bodies, and FAST EZ-EFI controllers and electronics for excellent power and reliabilty.

The boat owner has been very pleased, fuel economy has significantly improved over the Mercruiser carb setup,  and throttle response and mid range torque are much improved as well. Definitely a plus when getting a big boat moving.  In fact, the owner of the boat originally ordered a single system to compare the fuel consumption and power for an entire season before purchasing the second kit. He was so pleased with the result, he ordered the second kit in about a month!!  Congrats to MR Marine on a super clean install and a happy customer. Great job guys.

Steve Webb’s 8 Second Turbo Mustang.

Tuesday, September 7th, 2010

We have been working with Steve Webb for a while. We first did a small roller cam for his Naturally Aspirated 347 Ford that eventually went 10 teens at 128MPH.  When Steve decited to switch to a turbo combination, he called Competition Components.  Scott Brown spec’d the Ross pistons to fit the new Dart Block, as well as the cam and other valvetrain items. It’s first weekend out, Steve’s new combo went  9.40’s at 145 on  pump gas with only 7 PSI of boost. For the NMRA Race in Columbus this past weekend, Steve decided to step on it a bit and run some VP Fuels C-12 in it and give it some more boost. First pass off the trailer, he was rewarded with an 8.90 @ 157 with 14psi Boost. Steve kept leaning it out over the weekend, and by the time the weekend was over, he had run an 8.70 at over 159MPH. Congrats Steve! Keep in mind, this was only the second weekend out with the car at only 14psi. Lots more to come! If you get a chance, you should check out Steve’s Website here.

Here’s is a rundown of Steve’s set up:

  • Engine: SBF 364
  • Heads: AFR 205’s
  • Camshaft: Custom Scott Brown (Competition Components) Solid Roller Grind
