Looking good. With the bottle mounting right behind your seat and within reach, who needs a stinking remote opener. :D

On a wet kit (in regard to this post), it doesn't matter on the injector size because the nitrous system will add its' own fuel through a second solenoid. And the injectors will be injecting the same amount of fuel regardless of how big of a shot you are running.
So if there is anything that needed to be upgraded first, it would be the fuel pump before the injectors.

What good does it do with bigger fuel injectors when you are not getting enough fuel flow and pressure from the tank? :confused: (Provided that you have already max out your stock fuel pump, which is approximate ~550RWHP).
Running a big hp-shot on a wet system, if you are not getting enough fuel flow and pressure from the line, IT WILL RUN LEAN no matter how big your fuel injectors are. The fuel injectors are control by the PCM so it will not know when you are running nitrous and when you are not, let alone knowing how big of a shot you're running.

I threw out the blowdown tube that came with the kit. It wouldn't work with the bottle in that spot. I have a really big braided line that runs out below the car. You can see it in the pic.

It dosent matter what size the injectors are or if a MAFT is used, HE NEEDS A BETTER PUMP than the stock one to run the TNT 150 shot or there will be big problems:cry on the wet kit the extre fuel for the n20 is not coming through the injectors anyway, BTW i have 42 lb injectors and was lean with a TNT 150 shot.

I really questions whether the issue is with fuel pressure or with the size of the injectors and the air/fuel ratio.
In my experience I would say the injector size is the biggest limiting factor to not running a 150hp shot. In the earlier C5's, 97-98, the injectors where larger, as was the case with the F-bodies. On my 98 WS6 I ran a 150hp shot only because I felt safer with the larger injectors. I monitored my fuel pressure always, and utilized a Fuel Pressure Safety Switch.
I believe if you want to run a 150hp TNT kit, you should consider changing your injectors and use a MAFT to tune this set up properly. Getting a MAFT will allow you to trick the computer and allow more fuel into the system when running nitrous. The bigger injectors just allow you to maximize the amount you inject. The nice thing about a MAFT is it will let you recalibrate this system at the times in which you are not running nitrous so that you do not experience a rich condition at these times.
The high flow fuel pump is nice, but it is not going to do much for you unless your injectors meet the amount of added fuel being pumped to them. And the regulators are only available for the earlier model C5's anyway.
My last suggestion would be to pick up AutoTap or go get your air/fuel monitored by a local dyno shop so that you cantune the MAFt accordingly. The little autometer air/fuel gauge like I run is cool looking, but I don't trust it for it's accuracy.

LS1 fuel pump and injectors will handle 150 RWHP shot of N20:)
What I have read on other forums. Problem with TNT kits are, TNT underates RWHP numbers, for marketing purposes:( Underating RWHP numbers makes TNT kits look like they are producing more RWHP from their kits, but in fact TNT is just jetting more N20 into their kits.
So if you buy a 150 RWHP from TNT, you may dyno 180 RWHP, as TNT kit is adding more N20 to produce the extra RWHP number:(

Why did you have your solenoids mounted right in the middle of all your engine heat :confused:
Solenoid failure is your major concern with any N20 system.
Heating and cooling of solenoids over time will cause failure on a steet car.
Mounted my solenoids on front frame member, away from engine heat :cheers:

I did the same as you, mounted the solenoids right on top of the fan cover. From the several nitrous cars I've seen, including well known ones, they all mounted their solenoids on top of the motor right next to the intake manifold.
I'm not sure how much heat these solenoids can take, but one thing for sure....I wouldn't want to test it on my car. :D

I'm much more concerned about what shot size I can run safely with a stock fuel pump.
Besides when the engine does go, either from mileage or from NO2, then it's just a nice excuse to get a 427 C5R block! :lol: :lol:

Hell, just do it now! Why waste the money on modding this engine, when you can put it into the other engine. I wish I could this year. Hopefully next year if all goes well. Eric

Besides, I can always just leave the TNT stuff on and hook it up to the 427 :D

Re: TNT NITROUS INSTALL IS DONE! ... FINALLY! :) (Tuan Le)
By no means will the factory fuel pump max out on ANY of these aftermarket N20 kits, TNT or any other. That fact that you believe it will seems to me that you have been lead to believe this by someone who is trying to sell you a bogus "high-flo" fuel pump, or your trying to justify your own purchase.
The larger injectors are proven to run fine under normal operating conditions (ie, factory fuel pumps, and fuel regulators) as long as the computer is tuned accordingly. I ran 36# injectors, a MAFT, and a 150hp TNT power ring system on my '98 WS6. I never upgraded my fuel pump, nor did I make any changes to the regulation of my fuel pressure in some 25,000 miles. The car still runs strong today at over 75,000 total miles (with the exception of modifying the transmission and a couple sets of tires). I doubt seriously the fuel pump in it was any different if not less than what is run in my Z06 from the factory.
Also, the assumption that the TNT 150hp kit pulls close to 180rwhp is a little far fetched. It seems the Crank and Chrome episode has done more than wet our tongues. In my experience the other kits are under rated, but to say the TNT kit is over rated is going to far. I have no dyno numbers to suggest that the TNT kits push anything else than pretty close to exactly what they claim. Don't let the graphics fool you, this is my second TNT 150hp kit.... I think I have some experience with them.

So you've ran the TNT 150shot on two cars for over 25k miles with no problems?
Hmmm.. I want to run the 150, I want make sure it's safe, but I also don't want to get ripped off for a new fuel pump if I don't need it. :confused:

Unless you'll be going over 550 RWHP on the spray, you will not need a bigger fuel pump. If you had H/C and sprayed 150 shot, then you would need a bigger fuel pump ;)

Where did you get that blue fitting that connects to where the blow down tube would be? Is that a NPT to 6AN fitting?
