Nitrous

How did the old NOS kit work? I assume they had some failsafes in place.

This $785 kit from ZEX is for the LT5 powered ZR-1 Vettes. Its a dry 75-1254 hp kit.

Heck N.O.S. even used to have a specific kit for the old Crossfire dual TBI engines. Dom S is mentioned as having a Crossfire Vette that ran a 13.3 in the 1/4 running Extrudehoned runners in an old 2006 post.

Now this just got interesting.

I said 100 to be super safe and never have any issues hitting the nitrous all night long! The motor is stout enough to take a harder shot of nitrous and still be o.k.

No doubt. Gas has always been the most economical way to add power. And lots of it. For those of us that are modded even a quick little 75 shot just to be extra safe would be a real blast.

Nice.

Been thinking about nitrous oxide and methanol injection.

The 75 - 125 hp with a small shot of methanol should work fine for a easy 11 second car.

Got a wet nitrous kit need:

*Window Switch
*Prom setup or way to retard timing

purchases an MSD window switch http://www.summitracing.com/parts/msd-8969/overview/

just need to address timing

[Billy Mild]

Can't you create 2 tunes with using the power key function? I would make it normal power would be Full timing, then when you click the key over to full power it would retard the timing.

No, because I presume you'd want to still have access to full power operation when off the bottle.

What I'd recommend is wire the window switch into an open input on the ECM and apply a spark retard when active. Alternatively, you could have the PT Open spark tables active when the window switch is closed (versus when the secondary bit is set). This becomes a lot easier if you don't have secondary throttles.

Note: the later calibrations have exactly this feature, although the tables are zeroed. The EBTCM sends a binary signal to the ECM, which then retards timing by a specified table amount. That was the secondary form of traction control (spark retard), the first being mechanical throttle modulation.

I meant have both settings be "full power" where they would always open the secondaries, but one of the two power settings had retarded timing.
