OK I haven't posted anything lately here is a quick fix for this week this is one of our MB650na based on a 540 ci Dart block Lunati rotating assembly custom cam and ported Brodix heads I used a 9022 holley with a Dart intake for ease of use this engine made from 3000rpm to 5400rpm over 600 ft lbs of torque at 5500 rpm it made 599 ft lbs we are trying another port configuration with our standard camshaft design and were making more torque for a longer period and the engines are idling like taxi cab motors I made 16 pulls on this engine and used 6 gallons of fuel this is due to our new o2 sensor set up in each port with the stager jet set up I have in this engine we've picked up power all up and down in the RPM range . As far as I know this o2 set up is being used only by manufacturers and I can see why it's expansive as hell but it works a blind man can tune with this set up. Hope you guys enjoy.

This O2 sensor set up it's been out for a while but just recently has it come down in price for a working person to be able to afford it I've heard of manufacturers using it and the second it was at my reach I jumped at the opportunity to purchase it for development purpose here in the shop the way it works is there is a O2 sensor in each cylinder pipe so the person can fine tune the carb or specifically the efi set ups . You are able to track it through the rpm range and it works separate to the dyno it runs off the comp in it's own program.

Here is the finished engine at the cabinet shop ready for shipping with all accessories and custom wiring harness installed .

What back4more said. Are those Jesel Sportsman Series rockers? Also what comp. ratio are you running Laz?

Strip Poker 388

iTrader: (6)

Laz I see you said your trying different port configurations.

Are you doing this or Dart?

And are you seeing much difference than there standard CNC port configuration???You must be doing a lot of R&D on getting these #'s

We've been running the Jesels in our Poker run engines since they came out we haven't had any negative experience from them they hold up like everything they build. The port designs we're buying heads with their ports we modify them from there to get the velocity and volumes we're looking for and then send them back and have them digitize the port for our next job . This is expensive and time consuming but it's paying off with good numbers. That's what it's going to take to stay ahead in this game.
