I've built trannies for over 30 years and run N20 since the early 80's. I've never had a problem using the N20 all the way down the track and through the shifts. I use a 4L75E with 200HP and planning on more this year. It is no difference than having a motor at the horsepower that the nitrous increases the power to. If you cut the system, it would be like Torque Management with the ignition cut out between shifts. And yes you would be losing ET! There would be more trans problems if you pulse on and off the N20 between the shifts as the pressures would fluxuate and probably smoke the trans. I would not use over 100HP of N20 on a stock trans and stock motor, (400-450HP). It would be time to get the right tool for the job, (getting a BUILT trans). Good luck.

Anyway like I said before, w/ a good nitrous controller (window switch, wot switch, etc) spraying through the shift on the T56 is completely unnecessary.
For the automatic guys though I can definitely see how it would benefit you, especially if you want your best ET.

Kinda what I was getting at w/ the whole
thing. I would never try to spray through the shift on the T56. With nitrous and/or fuel still spraying the split second between shifts through the rpm drop, I can't see how you wouldn't at least blow apart your intake the second you get back on the throttle. Unless of course you're power shifting w/o even lifting off the gas....that's a whole different argument right there.

I did until my trans took a ****.
I sprayed 125 and bang the rev limiter on its last pass, engine still in good condition.
But mine did 135k on it and 5 bottles through it.

I do in the Nova![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
When I ran a supercharged stick car we never lifted the foot off the throttle.
That was a TKO 600 that was Face Plate or Pro Shifted. The RPM would spike to the limiter for a moment but you could barely hear it.
I would suggest a window switch set up about 500 RPM below your rev limiter.
If you miss a shift the only problem you will have is one of the mechnical mass spinning to the moon from being unloaded![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)

Cam72aro and Robin L(even though yours is better suited for the abuse), you guys are just braver than me I guess
A very good point. However I think you're missing mine. This is why I keep stressing the importance of a good nitrous controller...I'll use my setup for example...I'm running HSW's MicroEdge which has a 'Pedal Delay' feature for the exact reason you stated above. If I let off the gas due to wheel spin and then get back on it, it allows my car to gain momentum/load the suspension before the nitrous is activated. A progressive controller could also be used in that situation to help keep your *** off the wall

Also, its can be way dangerous on a higher powered car. Every time you shift, and disengage, then rengage the nitrous, the possibility of breaking the tires loose is greater, along with loading and unloading the suspension more and less.

I spay thru shifts now @ 150 hp worth of nitrous, and sooner or later when I'm trying to put 450 worth of nitrous thru it guess what.. I'm still spraying thru the shifts.
Nitrous is on @ WOT as soon as the tbrake disengages, and it stays that way until I take my foot off the floor, something else that doesn't happen until the end of a pass LOL.
