Blown 346 Posted December 13, 2012 Report Share Posted December 13, 2012 I myself would go with 42 LB injectors. Then you wont run out of fuel and the injectors wont be close to being at there maximum duty cycle. Quote Link to comment Share on other sites More sharing options...
Blazerdave2000 Posted December 13, 2012 Author Report Share Posted December 13, 2012 Gotcha thanks. So would u still use the boost a pump control? I'm new to the fuel injection world so I'm trying to learn and figure out everything lol. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted December 13, 2012 Report Share Posted December 13, 2012 I would, Its not going to hurt anything. it will actually help your existing fuel pump not work so hard. Quote Link to comment Share on other sites More sharing options...
chpspecial Posted December 13, 2012 Report Share Posted December 13, 2012 I would, Its not going to hurt anything. it will actually help your existing fuel pump not work so hard. A BAP will make a fuel pump work harder. And will likely shorten the life of the pump, however, I have yet to see a fuel pump fail due to the BAP. I wouldn't just run a BAP though, I would at least do a drop in Walbro, or the inline Walbro. As for injectors, that depends on your HP goals and boost #'s. for >8 I'd do the 8.1l marine injectors, anything more I would bump up to the ford green tops (~52#) or the simmens dekka 60 Quote Link to comment Share on other sites More sharing options...

thomp62301 Posted December 14, 2012 Report Share Posted December 14, 2012 (edited) What boost levels are ran with the wipple? The reason I ask is I maxed out my 42lb injectors with my procharger at 12psi. I installed 60's Edited December 14, 2012 by thomp62301 (see edit history) Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted December 14, 2012 Report Share Posted December 14, 2012 Procharger at 12 PSI is making huge power. I had the a D1 with 12 LBS and I had to go from my 42LB ers to 60. The whipple like most systems come with 6 to 8PSI unless you ask for a upgraded pulley. Quote Link to comment Share on other sites More sharing options...
Blazerdave2000 Posted December 14, 2012 Author Report Share Posted December 14, 2012 You got it. I'm buying the whipple used from a good friend of mine. It comes with a 4.25 pulley I called whipple yesterday and they said that should be about 6 to 7 psi. So I should be good with the 42 lb injectors. I think I'm going with the deatschwerks injectors and the walbro pump. Can't wait lol. Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted December 14, 2012 Report Share Posted December 14, 2012 If your going to replace the pump i would use the racetronix replacement fuel module. Its a brand new drop in replacement, take out the old and put in the new. This is what i run on my truck. But also remember the stock pump can take more then the forum bandwagon will have you believe, i ran my stock pump up to 504 rwhp and at 7000 rpm before i finally saw it start to drop pressure. Fuel module, gm SUV, high perf. type 007. The reason the marine 42 pound injectors were recommended is because they are direct fit with no rail shims or pig tail connectors, and just about every tuner has the correct files for them. When picking injectors its very important to buy injectors that your tuner has the correct info for. There are a lot of tables in the tune that have to be calibrated so the truck knows exactly what that injector is doing. Buying injectors with out proper tuning info....is a crap shoot for your tuner. The green top injectors also have proper info for them, but will require shims, pigtails, and i think different o-rings...i think. Quote Link to comment Share on other sites More sharing options...
KrausMotorSports Posted December 14, 2012 Report Share Posted December 14, 2012 Good info Brad! On my truck this same whipple I saw up to 10lbs on cooler nights. Any reason why mine would see that much boost while the whipple rep claimed 6-7 psi with the 4.250" pulley? I was also running whippletronixs(junk).
