What is the main difference in the DD1 and the RV275 injectors. Also cost difference.

 

Horsepower rating DD I = 50hp 275=40hp<br><br>Cost DD I = $400 275 = $250 to $300<br><br>The DD I's will be closer in flow then the Bosch 275's

 

Personally I wouldn't get anything smaller then DD2's. Both 275's and DD1's are only a slight increase in HP. If I remember correctly Lawrence told me that the 2's were his coolest (egt) running injector. I know that this wasn't what you ask but I thought I would pass it along.<br><br>Good luck with your decision.<br><br>Doug

 

DDII's, 80hp and $460.00 or so. They work extremely well with an EZ which is what I believe your signature shows. I tow an 8500# 5ver occasionally with mine. Your signature, unless I missed it doesn't show whether or not you have an automatic. Stick or auto, doesn't matter, you will have to upgrade that portion of your drivetrain and even if you continue to use the 275's and EZ you will eventually have to anyhow. When you move up from the EZ to the Comp, and you probably will, still an excellent option with the DDII's and Comp on 1x1 which is how I prefer to run when towing.<br><br>Roger
