Dry Dyno Run Here's a dyno sheet, on an absoulutly bone stock LS6, except CAI and self tuned. A quick run down, jetted for about 135rwhp, dual stage dry. You can see where 2nd stg comes on 4100rpm, then slippage on the roller? 2nd hits like a Bull on Crack. I plan on adding a third stage and it will be coming on about 5000rpm, and then I'll have a more linear torque curve. I am also running a fuel curve that is leaner to start then hits the richest point at torque peak, then leans out more as it goes to 6500rpm. So, 11.8 tapers upward to 11.5, then tapers down to 11.7. This will slightly change with 3rd stage. 480 peak HP and 505 peak Torque. This was done on a Dynojet using the new Federal Guidlines/Software. You can add about 10hp to this to compare to old software (new cars are rated this way).
Any comments, suggestions or insight are welcomed.
Oh, the n2o run in my sig was done on a smaller jetted hit than this, maybe tens tomorrow, if weather holds?

Well because the system is designed for a 200/250 shot and that's what I have right now. You don't see the potential of the dry here, an absouletly bone stock, no headers, long block running in the 10's on a little over a 100shot (most think dry is weak-dummies). It seems to me that it's working pretty good set-up this way, and 1.53 on drag radials. There is much more, I had showed up at dyno day to just hang out and got talked into putting my car on dyno, I allready new it was around 500hp by my times. I have some mondo jets coming, and just picked up a mondo set of injectors from a fellow Z06 bud today. I drive my car hard and each step up the power ladder is made carefully because my motor is going to live. 550/600hp is my current goal on stock long block.

Great dyno day man!

I do realize the potential of a dry setup and I know ur #'s are awsome for what u've got done. what I really wanted to know was would u get the same hp on a single shot that u got on a dual?

Robert very nice results. I am trying to figure out when I can hook my adj window switch to activate the 2nd stage on my dual dry setup now. And of course why stop there right? Need to get some more parts...looking for another 5177 kit, and convert over to a -6 mainline, the -4 aint going to work much longer

Nice numbers. I was a dry hater for awhile until I realized that with any setup, it is imperative that you have to tune it correctly for it to work to it max. With this current setup you have, do you have the same tune for N/A and what is the AFR? I know that you can retain the same tune for separate timing, but was somewhat unsure about the AFR. Does the MAF table need to be altered for the AFR on spray to compensate for the fuel.

Currently I have have the same tune that got both times in sig, basic a/f is majority of time at 11.7 and timing is currently at 22*. With this said, when going big, the benifits of dry is you can have truly 2-tunes in one. later models in HP Tuner have a IAT vs Fuel Adder table, and it comes zeroed out. What you do is log temps n/a and on the spray. You will see temps much lower than anything n/a. So, in these areas you can add a fuel multiplier to richen things up. What this does is add to your existing multiper in your WOT Power Enrichment. Conclusion, you only richen things up when spraying and have optimum a/f for n/a. I have just started playing with this and looks promising. The dual tunes for timing can be found in my Web under links, a write up how-to. With dry, you can truly have two tunes in one. I have altered my MAF freqs, but for my Vararam, not the spray. The guys having issues with a/f on dry usually are rich and this is a nozzle placement issue, imo?
Cat, thanks for pointing out the torque split thing. On the vettes our rears are less than ideal, and a all in one torque blast in first gear can shorten the life considerably. Also, a nitrous car with the torque spread through out the run will in fact beat the all in one off the line car.

Yeah Robert it took me long enough to join up eh? Now that rainy season is here I will spend alot of time indoors. Just for fun I made a graph using the power curve for stock Z06, your NOS pull, and the STS combined. I can post if you wanna see it. Here's what I'm thinking... Add a kit to run about 6psi by STS or TTi, get it dialed in, then spray it.

Here is a combination of dyno sheets. Alot of numbers are estimate from graphs found on the web. I took out the spike in yours to make a smoother curve.
Tell me if this page works or not. It should have tabs at bottom left to view HP, TQ, and the Data.
