I tried the search and didn't find what I was looking for. I want to spray my car on top of the H/C but I found that my injector were at 95% would I be able to spray my car like this. The kit is a wet kit so the nitrous won't pull fuel from the injectors. I also have a walbro fuel pump but I'm kind of worried about putting it in because of having to drill a hole in the fuel bucket. I was wondering if anyone could ease my mind about this?

 

Anybody? I've 15 views no one can leave a post?

 

wow maxing out the injectors already. Eric sprayed a 125 shot (DRY) on his 26# injectors w/o a problem. Are you running really rich?

You probably wont have a problem w/ the walbro. I just like to run my tank really low when racing. Also I dont want to mess up the tank..

Here is the GP sale if you do decide to go w/ the racetronics.

Where are you getting your car tuned at?

 

Well I maybe running a little rich but the O2 voltage is running about 890 for both O2s and thats what I tunned by. I going to borrow a O2 wideband and hook it on Wednesday and find out just how rich or lean its running. When I use Atap at 100% my injector duty cycle was 95%. The weird thing is they weere at 75% duty cycle at 93% throttle. I wan to spray on top of the H/C but I don't want to put in the walbro and screw up my fuel bucket. Would my stocker hold on until I get another fuel pump?

 

i wouldnt run them past 80% duty cycle

 

Like he said. Pick up some FMS 42lb'ers from ebay for 240 plus 10 shipping. I maxxed my 26lb out at 110% on a 100 shot and stock motor.

 

Well I found a good deal on some 36lb injector for $200, that takes care of those but what about my fuel pump?

 

i have a racetronix 255 lph and its a nice unit and you dont have to cut anything up in the gas tank, its a direct replacement

 

I've seen stock motor's with just headers hit duty cycles of 95%.H/C setup's hit 140% and run for years with no problems.
As for spraying on top of that,more than likely the pump won't keep up.Drilling the bucket is no big deal.We've done a ton of them like that

 

I normally run my tank down to "E" have you seen any problem with that or starving the motor?

 

NEVER run your tank to E, although the stock ls1 pump system is designed so you can run low without starving the pump and eventually over heating it and so it wont slosh around and give you pick up problems, BUT you will suck up all the nasty **** in your tank, i wouldnt recommend going under 1/4 tank

 

good info guys!
