I have a 68 Camaro with a LS2, holly terminator X with a speed density tune. Its a street car but i want to take it to the track a couple time a year and spray a 150 shot. Ive had both wet and dry but the dry kit i had was the old NOS dry kit that screwed into the airlid 22 years ago lol. I think i have 42 lb injectors but id have to double check. Im just gonna use the tune thats in it now and retard timing and control nitrous with the terminator X. Anybody have any experience with a Dry shot with a speed density tune?

 

you could do a simple NX proton wet kit with single shark nozzle for pretty cheap, and just get your fuel from the rail. very easy set up and it works. i never really got why people liked dry systems so much, its easier to set up a wet system and not worry if you have enough injector.

 

Just use the Holley to trigger the N20/add fuel and pull timing (if needed). As long as your duty cycle isn't maxed NA, you should be fine. You'll have no fuel distribution issues using your injectors for enrichment. I usually set it up rich. Test, and slowly lean out the fuel watching MPH. With E85 having it rich cost me no MPH and I didn't pull any timing. Was 13.5 AFR NA and 11.0 with N20 active. Didn't pick up any MPH leaning it out.
