my car is making right at 420 RWHP on motor and I am running a 125 dry shot I was wondering if the 30lb SVO's I have are to small for my set up and I should get some 36lb injectors ?

 

Good question for the guys in the N20 section.

 

30 lbs should be good for your horsepower level. Because of the higher fuel pressure found on an LS1 your actually running a much higher level thru the 30 pounders...think like 36-38lbs. How is your air/fuel ratio? That is one way to make sure your engine is getting the right amount of fuel.

 

I have a setup similar to Street Racer, but I am running stock 98 injectors. These are 28.6 lbs. from what I've read and heard. My o2 numbers at the track have all been acceptable with a 125 hp shot. Does anyone know if I would need to change the programming if I went to 30 lb SVO's. Did you Street Racer? Thanks for any info.

 

Hey you actually need a 34.3 lb injector but i would just go with a 36lb one so you don't have to run such a high duty cycle...

I didnt have a MAFT or anything for a bout a month and my 02's were at about 930 if I remember correctly , but I did use a MAFT for a while with the HPP3 I leaned the idle at 6% and it put my 02's at almost -0 at idle and leaned it out 8% on the WOT and my o2's were at 900.

 

With 420 on motor and wanting to add some N2O, I'd do 36s w/ custom tuning to be on the safe side. You don't really think 125 is all you'll want do you? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
