Ive had nitrous on built motors and never went crazy with it and never had any negative effects. The LS is a stock motor and just needs a little more HP at times (and a rear end/gears lol) but i was wondering if a small dose of laughing gas would be alright on this motor/tranny. No more than 100hp DRY shot. I figure the transmissions are the weak point in the drive train and would prefer to not replace that anytime soon. I have 84k miles and it runs great as is but just sluggish compared to what im used to in my cars.
75-100 Dry Shot??

Spray Use
In expectation of finally installing the 'toughened' AJ 27 engine I'm slowly putting together, I've put in, and used, a 400 wet shot NX system including a stand-alone methanol fuel package. (See 'Land Speed LS' in the HP section). Although I've experimented with as much as a '150'/gasoline combo, I've only used 100 of N2O with the methanol.
You'll need to use an SCT tuner to boost line pressure and firm-up shifts. And I strongly suggest the use of a wet system.

most stock fuel systems only have <25% range within their self-management - so they are not suited for dry systems. when you look at the stock bolt-ons from Holley, NX, ...etc they all recommend wet systems for modern EFI cars. The fuel pump can push it, just the returnless fuel system is not idea for a sharp spike in demand. It doesn't add much cost since you usually splice into the fuel line near the rail anyway.
I have experience with N20 in small block EFI Fords (fox mustangs), we sprayed big DRY shot but we also had big FPs and Injectors. I figured for just like a 75 shot that it would work alright on this thing. I will research WET spray more though.
go wet for sure. i think you'd be pressing your luck with a 50 dry shot on a car with any kind of mileage since injectors might not even be able to handle 25% overhead.
stock fuel pump should handle 100 just fine- mine did. use an xcal to look at the fuel pump duty cycle (double the reading... 45 would be 90% usage)
i would consider a progressive controller a necessity along with a new fuel filter.

dry wont work . you need the wet for the fuel. the ls will not compensate additional fuel on its on unless you have a custom tune for that purpose. i did this 8 years ago on my ls, its nothing new. wet works great, dry does nothing at all. run a colder plug with smaller gap and you can run up to 100 safely. ive done it on my v6. ran 80 shot for 5 years and more bottles than you can imagine
