Nitro Dave's Stock TB plate Dyno and ET comparison.
These results are my own and I have not spoken to anyone at Nitro Dave's about them. I put this information out here for everyone to read and draw your own conclusions from. They have not been influenced in any way or by any one. All passes and dyno pulls were made under VERY similar weather conditions with the pulls and passes on the plate actually being 3 and 5 degrees warmer which may or may not have hurt the output of the plate just a touch. So without any further ramblings here are the results for the RWHP/TQ dyno numbers with my combo which includes a stock LS1 intake, TB and heads. A camshaft that is 221/221@.050 .558/.558. TCI SSF that has been tightened up to 3500, 3.42 gears. All dyno runs were made with 125 shot in a single NX fogger nozzle and 125 shot on the plate.
Dyno results.
Single NX nozzle 125-shot.
402-RWHP
398-RWTQ
Dave's plate 125-shot.
420-RWHP
418-RWTQ
Track Results.
Single NX nozzle 125-shot.
7.22@97.39 11.30@122.89
Dave's plate 125-shot.
7.15@98.34 11.15@124.39
I know there has been some back and forth about Dave's plate but I know for a fact that it does work better over a fogger for my car and that is not conjecture, just facts. I am NOT in any way taking anything away from NX's products as they make great quality stuff. It just so happens that the rest of my kit is all their products but the plate just so happens to work better over a single nozzle as it would appear to me. I would like to thank Dave, Courtney and Chris for their products and speedy service. Thanks again and I hope this information is able to help some out there who may be wondering what system to get for their ride. Take care.

Dave, no problem and sorry for not including them earlier. The readings on the O2 counts were as follows -
Single NX nozzle - 12.7:1
Plate - 12.5:1
The plate was a little richer because I was mixing jets so I am sure there is a little more to be had if I wanted to lean on it some but I chose to err on the side of caution right now with the stock bottom end. Hope this helps.

Neither because I always add a few gallons of 112 to the mix due to having a stock fuel pump still. Both got into the 12.9 (plate) and 13.1 (nozzle) range but that was just for a split second when the system was actually activated. I personally would NOT call that lean but I believe the end user would have to justify that for him/herself. I believe that the Racetronix pump is going to help even this slight bump. Now keep in mind I am NOT a dyno queen I am very old school about some things so on the last of the three pulls on each system the car was cut off and the ALL the plugs were pulled, inspected and changed between the two systems to keep any confusion to a minimum. I have to say that from what I could tell the plugs from the plate system were a little rich but again that is because I was monkeying with the jetting due to it being a fairly new product. I believe that if I had leaned the plate out a touch more, maybe a jet or two down on the fuel it would have picked up even more but I needed to get going plus I was tired. Hope this helps.

Very good info!!!!
I am impressed you actually took the time to pull the plugs to check them. I think between your information, the post of the video of the plate spraying and BeardWS6's post I am sold on this plate setup

I would like to see your spreadsheet just because I'm curious. Could you email it to me? Badhabitbird@hotmail.com
Thanks again for doing such a great report on your findings.

You want the LS1 single nozzle vs. Dave's plate correct? I will clip and shoot you the columns either this evening or in the AM if that is OK with you. They will be in a standard excel format. You are welcome and hope this helps.

I just look at different things on a dyno sheet, not just the peak numbers. I was curious if the power came on quicker with the plate and how long the power lasted before it droped off compaired to a nozzle.

Thanks for taking the time to do the test. I had wanted to see what the difference between the two would be. I have a NX shark nozzle and am on the fence over whether or not to do the plate.
Some say there is a small difference N/A; Did you see any?
