I have a set of Lucas/Delphi 42lbers from Racetronix.

I want to keep my dry N20 setup ( NOS5176) but have never tried it with hte new injectors and 383 stroker.

Does anyone know if these disc type injectors would not operate at the 80+ PSI the NOS kit send the fuel pressure to when spraying ?

 

I've operated mine upwards of 70 psi. Hadn't gone any higher though.

 

I was told by Jack not to run these at high pressure but I would be interested if anybody had went ahead and tried them at 90+PSI.

I don't think ANY hi-z injector should be run at 90PSI !!!

 

so do you think my injectors would be ok at 75-80 PSI when i spray N20 ? or should i jsut get a wet kit

 

Get a wet kit.
They are easier to tune.
Less potential problems.
The N2O jet helps atomize the fuel.

 

i understand it would be easier to tune, however the dry system is already installed and ready to go. I have the correct jets in already for the proper amount of fuel through the 42 lbers. i just want to make sure the disc type injectors would be ok at 75 PSI.

after the dyno if im unhappy then ill go to a wet kit. I just would rather spend the $1000 on something else than another N20 kit

 

Chances are you would be OK at 75PSI BUT ALWAYS keep an eye on the FP and A/F when tuning. Start with a small shot to make sure everything is OK before stepping it up.

 

All you would need for the wet kit is a fuel Noid and lines and a different nozzle. You already have the rest. Wouldn't be anywhere close to $1K
