That's what I've got on my car.
Please understand, the plate will flow more then 150, but I seriously wouldn't try to puch it much more then that, this type of setup relies on teh intake to evenly distribute the nitrous, and I promise, going more then 150 is putting more to #7 then the rest.
At 150, the distribution is good, and the plate hits good, power gains are there, takes my 3350 lb car to 9.5x, and it ran 10.5 n/a last year at 3500, run that thru a calculator and you'll see the #'s are right on, 9.5x @ 142.5+ consistantly.
3350 and 142.5 mph, run that in a calculator, not too bad of a power gain for a setup that made 470 rwhp n/a

Go ahead and make up your answers, but that's what it would take to be able to make claims like that. I know right now you didn't do it, and that's why your post holds no technical merit.

Didn't someone from HSW previously post that in the plate conversion that it is a different plate than what you get in the complete plate kit? That it doesn't support as much hp. If that is the case I would look to the N2O Outlet plate .

The Brute Force plate is different than the Sudden Impact plate. The BF is good to 200 and the SI is good to 150. Like stated above, it gets a little sketchy going more than 150 from any plate. These plates hit incredibley hard. Best situation (or cheapest which is a huge + in my book) would be to go dual stage with a nozzle about 4-6 inches in front of the TB as a second stage if you want to start throwing big shots at it.

What variables do you want, Here is the layout. Exact same car, same day, 2 passes with each plate, with each companys recomended jetting and bottle pressure, made 2 passes with the HSW swapped the plates at the track, took about 40 mins, then made 2 more passes with the N20 Daves plate, A/F on both passes were 11.6, I do not think a whole lot changed in DA in 1 hr, 60's were between 1.39/1.41 Nothing else was changed on the car. Same F/P for all 4 passes 58psi. Not that big of a deal, just my experiance and testing to prove to my self. Now both plates are being sold and going direct port. Yes I have had issues with HSW in the past, Not saying there product does not work!!! Just N20 Dave's worked best for me in my test.

how is this any different than running it all through the plate....all of the nitrous mixture is still coming from the front of the intake...
The issue with running large shots on a plate is distribution....the issue is you are relying on the flow characteristics of the intake to pull the mixture where it is needed.

I have very little experience with HSW as we have only installed a few of their kits supplied by customers .... As far as Nitrous Outlet, we have problably installed close to 35 of their kits over the past two years and they have never given us a problem.
As far as flow... we are running a Nitrous Outlet Plate on a customers 427 C5 and have been spraying a 200 shot with NO problems for about 25 or 30 bottles now.... Today we decided to see what a 300 shot would do on the dyno.... Car made 540/510 on motor and 495/490 on the nitrous tune.... First pull netted 849/1000 backed up by 847/996... This all happened at 4700rpm as the car went sub 10.0 and we had to shut it down... I have more jets coming for tuning in the Air Fuel this week.
Read ALL of the plugs after both pulls and they are all burning perfectly... #7 runs lean under any condition.....a big plate hit isnt going to change that. Read your plugs and get your tune spot on and hose it !!!!!!!!!!!

Don't worry Ray, if the military assignment cards fall right, this time next year I'll be back in TX. I'll show ya how well my plate works

My reason for running dual stage is that the second stage will soften the hit instead of pushing it all through the plate. I ran this whole year this way and every plug was perfect. 100 on the plate, 100 on the nozzles.
