Cool So i am into Nitrous

I am going to start to build onto my car some over the winter here in NY.
I will be adding an MS4, Yank 4000, Fast 92mm, underdrive, injectors, and a NX 100 pill wet shot.
My question is does the MS4 like nitrous?
& i am very new to nitrous, but i think i will be using a window switch which will activate at 100% throttle, how do you stop the nitrous spraying through shifts?
I am hoping to hit a 10.99 with the mods posted above and the mods i already have (see sig.) Yes i know i prob will break the 4L60e and the 10-bolt w/ 3.23s but that just gives me a reason to replace them.

MS4 is a good nitrous cam. Do you DD your car?

You set the window switch about 200 rpms below your shift point, this way it cuts off the spray while you are shifting and wont activate till your WOT and XXXX rpm again

WOT switch is different than window switch, from your post it doesn't sound like you have a WOTS

Most window switches now include a TPS activation switch. This will monitor TPS voltage and only allow the kit to activate at WOT.

Just about any off the shelf cam will respond to a 100 shot. You'll be fine with the MS4.

If you're that worried about breaking ****, get a controller. The Microedge will hook you up with all kinds of gadgets (TPS switch, window switch, and gear lockout) which can save parts. It's fairly inexpensive too.

A WOT switch to activate the window switch.
My window switch has the WOT switch built in so it reads the throttle positon sensor for WOT.. No need for both. Like what Ray said.

I tried having my window switch turn off the spray at a 100 rpms before it shifts, but sometimes it would have an issue up top and didnt like it. I raised it to match my shift points (mine is set at 6600 rpms) and its all good now.

My trans let go after 2 WOT runs after I installed my heads/cam.. Im sure yours will too.

My 10 bolt was good, I put down a 1.45 60' on it and **** loads of low 1.5X's on it. If you can control wheel hope, it can take a descent amount of power. But, one hard wheel hope, it will explode.

I have a WOTS and this





Spark Base: Adjusts the spark advance/retard at all RPMs
Spark WOT: Adjusts the spark advance at RPMs over 3000
RPM: Adjust the minimum RPM to activate the N2O relay
RTD: Adjusts additional spark retard when N2O is activated
MODE: A series of switches to set the N2O activation delay and maximum RPM

I run that in series with the window switch (bought it after I had the WS).. But, I have it unhooked as I was uncertain if it was pulling timing or not. I was going to get on the dyno to prove this other then a red LED that you cant see while under WOT.

Im just going to pull the N20 out and cap the fuel noid and see how much power I loose with 9* (what ever the max RTD can be pulled). If I loose power compared to the base pull then I knmow its working.

EFILIVE cant tell you as the timing tuner tricks out the crank sensor and wont show up.

Anybody want to throw in any tuning advice? I will dyno tune my own car.
The problem i see is that if i do a wet kit i will have to do a nitrous tune because the MAF is not picking up on it so my engine will not be running prime AFR and timing when its just on motor where if i go to a Dry kit my MAF will pick it up and will change the AFR and timing when the nitrous is spraying and when it is not.

with the timing tuner I have, I run an N/A tune. Then the Timing tuner retards the timing when WOT activates it and the pump for my stand alone tank. So I can run all motor or on spray, without sacrificing anything running all motor.
