i want to know anything i can about window switches and retard boxes

i know the basic on what they do and how they work but i need some refreshment

what are some good systems?
can u get these as one unit or do they come as seperated units and whats the best to get?

after i install my 224/230 i have an n20 kit that i will use 100-125 shot.with the cam tune i want to always have that power when im not using the N20.

thanks guys

Iv'e always had good luck with the MSD brand of electronics... retard boxes, window switchs, timing controls, Ect.....they're sold seperately to splice in to most any ignition......or you could get something like an MSD digital 6 plus box that will give you a better ignition over the factory unit, as well as having a good "spark cutting" revlimiter(not fuel), a single stage adjustable retard for when you spray....and then add the MSD window switch onto that...

 

Can you tell us what harness (part #) is needed with the LT1 for the MSD digital 6?

 

Looks like MSD 8877 for the single connector coil and 8876 for the dual connector coil.

I'm sure on the 8877, as that's what I have on my car.

 

can some one reccomend what window switch and retard box to use, do u need any other MSD ignition components if so.impretty new in the n20 area

 

Been looking for the same thing myself.....I see that some guys also use the Mallory 685 box. It has the window switches and a Retard in the same unit, and I think you can use the msd harness to hook up the Mallory?

 

.. If you don't want to go with the digital 6 plus box with the retard built in.......their "best" seperate MSD window switch(Digital with adjustable degree dials is#8969), and the regular one that uses the (sold seperatly) plug in RPM modules is #8956....... The MSD retard box is #8975 for the 4 stage retard... and #8970 for their 3 stage retard unit........

 

where would i be able to pick up a mallory 685?

i found one

looks like i may end up going with this system

whats everyones opinionon this unit?

 

I think it's not for our engine(s). The PDF says "For applications triggered by points". Unless I don't understand something....

 

it seems like many ppl are going with this unit in asearch ive noticed many lt1s using this system, its a universal system so we already know it will work with out cars

 

Then it is a good find as it's about $50 less than the MSD digital 6 plus.
I went into the Summit Racing store here and talked with three sales people, one of them was the parts manager. It wasn't an enlightening event. I'm on the hunt for information on these modules. I don't need the intensified spark but the ability to control the rev limit by cutting spark, retard timing and have an integrated window switch would be the answer to a customized nitrous system. All that would be necessary to add would be a fpss.

 

The Mallory 685 box is perfectly suited for your application. Get the MSD harness and the install becomes plug and play.

The 685 box has a built in window switch and a single stage of retard that is RPM activated. IMO, it's the perfect all-in-one box for a single stage nitrous setup. The best thing is that there are none of those stupid MSD RPM pills to constantly buy and loose - just a couple pushes of the button and you can control all of the box's features.

thanks guys

one more question

the box will only work when i arm the n20? as thats all i want it to do

 

Thanks Chip! It looks like my 95 will need the 8876 MSD harness and CamaroSS30thAnn will need the 8877 but I will have to take a look for the dual connection on mine.

As for your question CamaroSS30thAnn, it seem that the integrated window switch can be used to enable the n20 arming switch but someone else will have to give an experienced answer. I'm really glad you started this thread btw.
