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.

 

Ah, mine is set up differently

 

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.

 

My car is on the road one month of the year, then the other 4 months its at the track. the other 7 months is winter...

A WOT switch to activate the window switch.

 

yes that is how I have mine set up.
That sucks that you cant race for that long because of winter. I'm in FL so we race all year round unless ur ride broken

 

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.

 

whats the brand of your window switch??

 

waterbug, are you using a plate?

 

Yea, its the Nitro Daves plate I bought last year.

 

I have this one....



Which I also bought from Nitro Daves.

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.

 

i would also add a fuel pressure safety switch. it just saved me as my fuel pump went out a couple of weeks ago.

 

let me know the testing results

 

is that window switch pretty easy to hook up and get going??
i have all my switches for me to manually spray the car. you can see how thats pretty damn dangerous try to hold the car straight with one hand so i am looking at getting a window switch.

 

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.

 

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.
