Brett, is it worth the risk on a run that might not work?
I am pulling for you to make this work, but it is not worth dying over.
Trying to do this in one shot with so many new and unproven things going on with the car is putting a lot of trust in "Hope".
We never did find out if you are running a independent fuel system for the N2O, are you?
It sounded like from a previous post you were not.
Regardless, I do hope it works out for you and you stay safe.

Is it worth the risk.....hmmmm....interesting question...
My answer is, well SOMEONE has to try it
Why not me, at least I have driven Top Fuel cars at way over 200 mph and sometimes they went bang...
I do not personally think it a huge risk, at least not compared to some other things I have done in my life.
So why not
All the best Brett

How do most high HP dynos work? Are they all a big drum with some sort of friction load on the drum?
When Brett's doing the high speed attempt, the main engine load will be working against air friction and the partial amount to accelerating the 3600lbs of mass.
On a dyno, all that power will be pushing against the drum/roller system. Not sure if that will be harder or softer than air friction.
Just hoping if the engine should cease to keep rotating that the transmission will decouple and freewheel at high speed.

Good luck, my 928 brother.

So it's not a progressively controlled system?
I thought the multiple solenoids were so you could slowly add more and more NOS...
If you are going to dump it all in there at once, and without testing the fuel system capacity, then I will have to join the others saying that it probably won't hold together. All the people I know who run high horsepower nitrous systems, or who have turbos, all do it progressively. So that as they go down the drag strip, it adds an extra 200 horsepower at the launch, to control wheelspin, then as it gets part way down the track, another bank of solenoids fire, adding another 200 horsepower on top of the 200 that is already running, putting it at 400 extra horsepower. Then as they get to the last 3/4 of the track, the last set of solenoids fire, giving them a total of 600 extra horsepower. But the strain on the drivetrain is much less, with the boost or nitrous coming on progressively, rather than all at once... Even if you get the car up to 80mph before hitting the nitrous, it's still a huge load of power hitting the engine all at once. Better to slowly fire more and more solenoids as you go down the runway.
Anyhow, depending on how much time you have before the run, I would seriously consider just replacing the stock fuel pump with an electric, high capacity race pump.

Yes it IS a progressive system lol
Its just years in advance of American systems.....that MAXX EXTREME race controller controls all 8 solenoids at once and ELECTRONICALLY controls the percentages that they all fire at once...

brett, i was thinking about the dyno from the frame of reference of looking closely at fuel supply and seeing at what horsepower it starts to run out.. if my reading here on this forum is correct then the guys running 500 rwhp have uprated there pumps and im guessing this wasnt just for kicks. i want to see the car go over 200 and then drive home! thats what a 928 should do

theoretically you wouldnt even need the nitrous til you got above 160...stock your car will push that. by then the gearing would be low enough that id say the car could survive

Yeah, maybe that could be a good idea.
Run it up to 130 or 140, then hit the nitrous.
So it will give it that final burst of speed over the finish line...
I'm with Nick, in that I want you to succeed.
I think it would be awesome.
I'm just worried that if you don't do proper testing before the run, to check if the car runs lean due to fuel starvation, that it's more likely to just blow up, and then you will be building a new engine. When all you really needed to do was add a new fuel pump. The time and cost involved in getting the system set-up right, and running right, will be way cheaper than having to rebuild a new engine, and then maybe having that one blow up too... If you are going to blow an engine, have it be due to extreme power bending the rods, not by blowing up because you did not upgrade the fuel pump... A dyno will tell you your air/fuel ratio, if it's a good dyno.

Yes, obviously. Perhaps you missed the tongue and cheek intentions of my post. That's why I added the "Of course, that's easy for me to say thousands of miles away where I'm safe from the explosion."

From what I've heard, Green Bay Packer refers to a meat packing company somewhere in Wiscunsen. You'd be better served with a Seattle Sonics patch, since you may create a sonic boom if your gas pedal sticks...
