I have both kinds of kits and I have and old NOS dry kit from my '82 with a TPI swap (5115), and was just thinking about how it was able to be fired right off the line and I also have a NOS wet kit I had on my '92 (5151) that could put back on as a sort of "2nd stage" above like 3000 rpm to avoid that off the line wet flow TPI problem. what do you guys think?

 

what is the "off the line wet flow problem?"

 

What are you waiting for, put it on!

 

well I have run carburated style NOS systems (super power shot) and carburated intake converted to EFI with the same NOS system (super power shot with 5151 jet sizes), and the 5115 dry system and I could always hit the juice right out of the hole with those systems. when I put the 5151 on the TPI it hit like crap off the line (sputtering) but worked fine when hit at higher RPM. I tried different fuel pressures and could not clean it up. before it became a problem I pulled the engine for a major project. later while chatting here I got several people telling me to not to hit it below 2500 - 3000 rpm, not because the nitrous companies dont recommend it but because of the fuel distribution at the lower RPM sucks and that sputtering happens.

 

my 5151 system must be different.

 

the spraying below 3000 on a wet setup is because you will get intake puddling.. intake puddling of the GAS and nitrous == boom.
