hey all,
im about to order a TNT F2 wet kit, along with all the misc parts ill need (WOT switch, FPSS, window switch). im going with the F2 because im planning on running a 100 shot now, then later on stepping to a 150 (after a few other mods). my question: is it ok to run a 100 wet shot on the stock tune, or is the stock timing too high for that size shot? i checked the a/f ratio and the car is running a little rich after headers. cars and mod in the sig. thanks!

 

i ran a nx 100 shot on my bolt on car with stock tuning and it was fine. the tnt kit is jetted a little different, but you should probably be ok.

dont know if i would try a 150 unless you got a fuel pump.

 

If you take your car and actually dyno it, using the A/F sniffer, you'll see that most header cars are running a lot leaner than you would want to on nitrous.

One of the ways and the way I solved this is by using the MAFT. With it you will be able to lean it out on engine runs, and richen it up on your nitrous runs. Could you run it on the stock tuning? Yes. Would it be safe? That would be a roll of the dice. Why would you want to take a risk when for say $150 you can use an MAFT and get a better run and a safer one? Of course LS1Edit is the best solution.

ok, so if i get a dynotune, and make sure my a/f is ok with a MAFT, i should be ok as far as tuning goes? stock timing is ok?

 

stock timing is pretty conservative due to the car being able to run on lower octane gas.

 

Donate52. I ran my 100 shot set-up on stock tuning, with the aid of the MAFT.

I ran a TNT wet 100 shot on my bolt-on car for a year with zero tuning. The kit hit hard and I never had an issue...

 

You should be fine with stock tuning, TNT kits run very rich anyway (mine was 11.0 AFR, N/A was 12.8). Best bet is to dyno it using the nitrous and see for sure. BTW, I would not tune your motor to a wet shot, I would tune your motor N/A then tune your N20 to your motor. Timing may be the only thing, and I would use a timing tuner for that.

what is the diff.

a wet or a dry kit?

what is better?

 

The difference being, a wet kit feeds the fuel via a solenoid (just like the N20) and depending on the fuel jet size determines how rich or lean you can be. So you would not want to tune your N/A AFR to compensate for a rich/lean condition while running the N20, you would want to change the jet size. Now on a dry kit, you have no AFR adjustabilty except with a MAFT or LS1edit, so your options are limited to that. I prefer the wet kit for that reason, I don't like adjusting my N/A AFR...
