I was a little dissapointed until I saw this

Tires spinning on dyno :eek:

And what the crap is with the propane?!? never heard of such a thing

I just looked at the dyno with the base and two N20 runs, whats with the A/F ratio dropping off so soon along with the TQ and HP curves?

I'm stil learning about this whole propane injection set up.
So far the only cars I have heard of doing it are vipers.
They juice it w/ a propane kit supplying the fuel?!?!?!
Dunno

Ok, bit of researching done:
Why propane?
Cleanest burning, safest, cheapest, highest octane fuel additive available. No need to starve your injectors or add another fuel system

What you don't like the idea of a tank of compressed propane, a tank of compressed nitrous, and a tank of gasoline back there?? :D
You are correct

I thought propane was only for diesel, but I guess not... sounds like a good use for the grill in the winter ;-P

Yeah you can through some T-bones on the motor, do a 1/4 mile pass and then youve got some food! :D .
If I had a viper, I would not do that too it. But hey, if you own a viper, I guess you can afford a new one if something goes wrong!

Looks like this Viper needs some slicks or something better to launch on, that's a heck of a mph for only a 10.1, also a lot of hp to only be running that.

I'm basing this all on a certain Vette I know of that has heads, cam and 150shot running 10.5 @137mph with only 590hp.

Here's the site for the Vette: http://www.jperacing.com/corvette.htm

Here's a few posts from him:

The viper spun the tires on the dyno!!!
It still spun with et streets on the dyno.
It has a serious traction problem

Kendall, Jason's vette also has never had a great pass as far as bottle pressure goes. If you look at his dyno graph, it falls off at the top end from dying bottle pressure at the end of the pull.

That's the thing about nitrous, you gotta have ALL the liquid in there warm. Some people see their gauge get to 1100psi, and think it's good...by the end of a run, only 850psi. Why you ask? Because only the outside of the bottle is that warm. It's best to "cycle" a bottle in the heat, get it warm, cool and mix a bit, warm some more, so on until it's all warm. People would probably piss their pants if they did that real good, and then looked at their trap speeds, it makes a huge difference when you have 1100psi ALL the way down the track.

they'll need 2 set the suspension up as best they can for drag racing. I can see why the tires spun on dyno, too much tq and not enough give in the rear suspension. maybe drag radials on the dyno would work ;)

[Dirty8-un-Dreds]

I remeber when I saw this on www.norcal-ls1.net , started a big discussion on propane. Some guy down here, who if I remeber correctly was running a ws7, either that or a lt2 wanted to try to do it. Oh and yes juiced vipers are the shiznit.

Dunno<hr></blockquote>I think GodfatherZ28 from CZ28.com has a propane injection system in his Viper. You could always ask him.

Very true, bottle psi must be maintained, not just met off the line.
