Any users of NOS on board?

Postby ykf7b0 » Sun Dec 22, 2019 5:00 pm

I am thinking of installing a 50 hp shot on my newly built d16a6 and I would like to hear from all who now use it. I have experience with plate systems on my Mopar but none with a wet or dry systems on an efi system. Let me know what you have and how you like it please!

Really depends on what you're tuning the car with and its capabilities in my opinion. For EFI, if you're still on a stock ECU, then wet is probably the best setup. Most of the people I know who have done it have gone with Piranha Nozzle setups at the factory injector location on the manifold flange, and have a stand alone ECU tuned to up the fuel tables and hit the nitrous at WOT, so not your typical 'wet' setup.
I've never used it. My brother has, and we both know a lot of people who had it in the past. Honestly, with how far ECU tech and tuning has progressed, it's likely very safe now if you are willing to spend the money on tuning. I've been thinking about going with a decently sized dry shot on my cars recently just for the extra easy HP, but I've got stand alone ECUs already that fully support a lot of nitrous features/options.

The most ideal way on EFI something like below, but most people don't want to go through the work of setting it up, and just T off a line to four jets into a piranha nozzle at the flange like I mentioned above.

Car is still obd0 and with the d16a6 and I don't think I will convert to obd1. Engine is fresh with CP 9 to 1 pistons .020 oversize, head was cut .010, y8 head gasket, long ram cold air intake with K and N filter, AEM adjustable fuel pressure regulator, OBX 4-1 header, 2 1/4 exhaust with Magnaflow straight through muffler, and a 11.7 lb flywheel are the only deviations from stock. From what I've read so far, the argument is whether to use a wet or dry kit. Depending on the posting, some will claim a dry is safer and some claim wet will be more effective than dry. More recommendations and thoughts from you guys are welcome. Thanks!

So you are staying obd0 and limited to tuning.. so my suggestion is small shot and wet.

I have a new Dynotune wet kit on the way and I can't wait to get it installed. I think I will start with the 35hp jets.

I need recommendations for a new fuel pump as my oem is on the fritz and, also to support my new wet kit. Again, she is an 89 si with a newly built d16a6 and I am jetting the wet kit for 50 hp for now. Thanks!!!

Walboro 255 should be more than enough.

I found this cool shifter ball with switch on ebay and wired the purge to it.

I found this to be the best place for me to mount the arming switch.

The NOS bottle doesn't fit my bottle mounts and I use it in my 69 roadrunner.

It pulls hard with the 50 hp jet set and I am impressed but this is addicting for sure! I just now installed the 75 hp jets and I will spray it tomorrow. I know I will be pushing the boundaries so I really doubt I will ever install the 100 hp jets.

Good stuff man. I don't recall what the D-series motors put out, but a 50 shot I'm sure makes a world of difference. Before you up the jet, I'd hit a dyno with o2 reading and see how much power it's making off/on the NOS, and verify that you're not running too rich or lean. What RPM range are you using it in?

I believe the factory rating for the A6 in an si was 108. I have been spraying anywhere over 3k rpm's. The nearest dyno for me is almost 2 hours away and it might be awhile before I get the chance to get real numbers and readings.

I should have stayed with the 50 shot. I now have the transmission out and looking for a no shift problem. Dang! :cry:

I found and installed another si transmission and all was well until...........
I stayed in the 50 shot just a little too long.

A bottle pressure gauge and bottle warmer are critical to maximum performance. I really can feel the difference between 750 psi and 950 psi.
