Hello guys, I'm actually a subaru owner but i recognize there is a lot of nitrous knowledge on this board.

my car is a 5 speed auto 2.0 liter with a good sized turbo. For drag racing It can't be launched like a manual and has to "Brake torque boost" to launch it, by planting both brake and accelerator to build some torque before catapulling it off.

I'm thinking of building the bottom end and adding a small 20 shot of nitrous (2500rpm) to get the RPMs up (3200rpm) where the turbo spools then i release the nitrous activation.

currently it takes 8 seconds to brake boost to a usable RPM, and i've seen a DSM guy do the same thing and got his down 2 like 2 seconds.

I'm thinking a 20 shot wet should be safe enough and strong enough to get the RPM up over what the torque converter is resisting.

I'm thinking these conditions to activate the solenoid:

1. A WOT switch - only activates when throttle is wide open
2. A pressure switch - only activates UNDER a certain psi
3. RPM window - only activates over a certain RPM, and off after an upper limit has been reached

Any thoughts?
