brobradh77 Posted November 12, 2007 Report Share Posted November 12, 2007 what r u putting down with ur setup brobradh , what pulley size ? I'm running a 3" right now and will be switching to a 2.8 with 60# here shortly I already have everything just waiting to do it. The walbro 255 fuel pump is more than enough.

For DR's they put all others to shame. As a matter of fact you probably wont be able to obtain any for a while due to the end of the season. they knocked .5 seconds off my 1/8. With my current set up i only ranmy truck one weekend. I was running 5 lbs. of boost and over 1/2 tank of gas with belt slippage and pulled 13.4's all day. My set up is a mid 12 set up I just need to get the bugs worked out. Quote Link to comment Share on other sites More sharing options...

No problem on the help. I went froma 3.2 to a 3 and used the same belt. The tensioner couldnt pull the slack out so I hasd to change out belts that monday when i got home. I should be 8-8.1 1/8 and 12.5 ish in the 1/4 with my mods. I'll get there. Quote Link to comment Share on other sites More sharing options...

04CHASE Posted November 13, 2007 Report Share Posted November 13, 2007 idc injector duty cycle. if your fuel press is 59 at your highest boost level at wot then your ok. when i had a single walbro and magnavolt i was seeing 50 psi at wot. so i had to upgrade to dual pumps. the 04+ guys have more work to do when upgrading the fuel system . but i am running a different blower so its not exactly the same.
