I finally bought myself a TNT nitrous kit, and have read quite a bit on this. I went ahead and got a MSD window switch and wanted to know what is a good rpm to activate and shutoff? I did a dynorun so I have an idea of where my NA power is at, and also did a/f ratio along with the dyno. Anything I should look at more carefuly. Thanks.

I ran 3k and 6500 with a 6600rpm rev limiter and 6400rpm shiftlight.

 

I'd go with a 3,000 RPM pill on the low side, and 6200 on the high side, if you've got the stock rev-limiter. You could go with a 3200 on the low side if you wanted to be extra safe.

For what's it worth, I've got a buddy with a 98 Z28 that sprays a wet 100 shot right off the line, with a stock convertor. The juice hits his motor at about 2,000. No problems as of "yet."

 

Ive got a 300o on chip and 6000 off chip with the stock rev limiter. Anything above 6k is cutting it too close on a stock limiter.

 

i have mine set at 3k and 6k. are you going to run a 150 tnt? if so, get a fuel pump in there!

have fun, you will love it!

 

I sprayed off the line at like 2k RPM, so I dont think you have to worry about the low end, I was spraying 150shot, btw

 

When you shift at 6600rpm from first to second/ second to third... what RPM is it? I'll bet it is above 2K <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
