Finally...some nitrous dyno #s with the NX Max II Basically just testsd the sytem out. The Maximizer II with wideband, the stand alone fuel system and the alltronics EGT setup. Its all working but will take some getting used to on the best way to extract and use the info. Tha maximizerII is very user freindly and was easy to use and make changes.
The motor is making about the same power it was on motor as last time except this time it was on 28 inch ET drags with 25 psi in them. It made a best of like 545 rwhp. I made the first run on juice with the setup starting at 0% at 3200 rpm and ramping with rpm to 50% by 6800 rpm. It made like 700 rwhp. Last pull was same start point but rapming to 100% (of the 200 shot jets) by 6800 rpm. On that setup it made 755 rwhp or so. Tq was very controlled...which is exactly what i wanted. It was a mild 669 rwtq or so. As a matter of fact the 755 rwhp was done with about 2 gallons of 100 octane and about 7 gallons of 93 in the main tank...and C16 on the front fuel system....FULL TIMING of about 27 degrees. No knock or detonation. That really because the mild TQ numbers along with the C16 accounting for roughly 25% of the HP being made. When I up the shot I will be retarding timing some and adding 110 to the main tank. AF will need to come down to 11.5 as well.
Overall I am very pleased with the initial runs. The next graphs I post on this combo should look significantly different, especially when FJO releases the multi point ramps. Tq will come on sooner and be more flat. And it will carry out to 7000 rpm without dropping off. Goal is 750 rwtq at 7000 rpm (999 rwhp).
Here is a graph from today.
The Max II is SEAMLESS in the RPM mode. I cant wait to hit it with the 450 shot.
BTW...I drove the STREET car 25 miles in rush hour to get to the dyno

a friend of mine was lifting the heads on only a 300 shot, how do you plan on keeping those heads down on 450?
time to take that to the track!
ready for willie?

most of the time heads lift due to detonation. If you notice the TQ on these runs was much less than the HP. Tq is a direct measure of cylinder pressure (overall). By contr0olling the Tq you can make things live alot longer. I have no doubt the engine could handle around over 850 ft/lbs of rwtq. To get 999 rwhp I will only be seeing around 750 ft.lbs. Thats not excessive. But it will have the TQ where is counts...later in the rpm range.

I agree, his motor should have held that shot no problem. he did manage to go 9.13 before things let loose though.
i'll say it again, do you think you're ready for Willie? (turbo stang)

Very nice numbers! Once you start to hit it with a bigger shot, how long do you think the motor will last before it needs to be "freshened up"? For example, over the course of a year, do you need to do anything to your motor other than change the oil and other little things?
