I am running a dry 100 shot on H/C setup. I just recently dynoed and show only a 50 hp jump from my NA numbers. The torque did get come up to 505. It is kinda got me stumped???? Before I did any real mods to the car I came in at 420/535 on the same setup. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
I do monitor the car often and see no evidence of a problem....It runs strong NA or on the gas.
The obvious things have been looked at....It has to be a port matching problem or something....I know the TR224 is not the optimum cam for gas...but 55% eff. is way off the expected 75% on a dry system.
Any help here is appreciated!

 

Forgot to mention the tank pressure is optimum at 1050-1100 lbs....

 

I had the system installed...where is the filter?
Thanks.

 

Dump that dry kit and get a TNT wet kit. Or convert yours over it's easy.

 

what size fuel injectors do you have?

 

Welp...tore apart all the fittings and checked the filter screen. Nothing there. This is kinda weird...it must be cam related.. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
I am only showing a max 75% injector duty. Something is holding it back...maybe change to a 230/238 grind <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" />
I may also go to a ATI setup <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />
Decisions..decisions.

 

Try a 900-950 bottle pressure.....I picked up 45 rwtq by lowering mine.....

 

Check and make sure you didnt get a bad bottle refill.Check your micro switch and see if the kit is comming on and off due to bad contact.Good luck.

Can you provide some logs of the O2 sensors or AFR while spraying? That would help figure out what's going on. What's you're fuel system like? What system are you running and what jet sizes? Where are you're nozzles? How are the feed lines routed.

Just went and checked the switch connections and seemed good. I did not install the FPSS because I have heard that they can kill your power <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> ..I did not have this problem until I installed the TR224. I may go back to the stock timing curve and try that out....but there can't be that much hp to gain in timing...

 

Weigh the bottle. You must have 3 to four pounds of nitrous at the min. At 3 pounds and below performance can drop off greatly. It is NOT your cam....
