KA ha always been set up for handling foremost.
If you can provide the test conditions and and efficiency index for these conditions I will conduct the same tests on my IC's. It will be back on the engine dyno in December. From what I have seen to date, I believe the genie is out of the bottle.
Even if we are wrong, the gains from this process are staggering.
Let's stop rah rahing for a certain team or manufacturer and strive to find the actual truth based on some sort of a quantitive test. I really have no problem is saying I'm wrong. I do know we have taken a very good set of IC's and made them much better by applying a heat dispersant coating. This is a fact. I dare say that if you applied this same coating to your existing IC's you would very much notice the difference.

Plenty of hp? Maybe, I'll tell you after the GT40R turbo's have been tested. Actually, I have a little problem. Purely power, the GT40R's look like the way to go followed by the GT35R's. Obviously, these wouldn't work well on the track. The GT30R's have great response but they run out of poop just as the cams are starting to really come alive (around 6700 rpm's).
Do you have any suggestions?

Best of both buddy... Too bad our ECUs/set ups don't allow for that. The RX7 was interesting like that.

That will be like flipping the switch when the boost comes on. Way cool project man when you get it done I will come to San fran just to check it out

Actually, the power is rather linear. Yes, the turbo's start to spool at about 4400 rpm's and really take off around 6400 rpm's. But the jolt is disguised because the nitrous activates at 2600 rpm's under WOT. It is programmed to start with a 10 hp shot and adds an additional 10 hp shot every tenth of a second. It continues to add nitrous until it attains a 200 shot (two seconds) where it levels off until WOT is released.
In other words the turbo's feather in and then they add power.
Their is no violent kick when either the nitrous or the turbo's activate. The two systems compliment each other.

This was the reason many extra steps were taken that otherwise could have been bypassed. Steps like Inconnel valves and coated combustion chambers, exhaust ports, piston tops, valves and valve springs to control the heat.
To allow the motor to live ...... things like three index oil pump, stronger case, made to order pistons, rods, tappets, valve springs and larger diameter valve stems just to mention a few.
To allow for less friction and internal windage .............. things like coating valve stems, piston skirts, berings and oil pump gears. The crank was knife edged and the case boat tailed. These little things really pick up small amounts of hidden hp as a bonus.
When we started this project our dream was to design and build a motor with the power somewhat like the old Porsche Can Am monsters.
The nitrous is not essencial to this motor. The motor does not depend on it for power. It is was to assist the turbo's.

how is it going to be possible to deliver all that power to the ground?

Alot will have to do with what gear it's in and what rpm it's at when you open her up.

CJV-
In my 996 turbo, when I hit the NOS I get instant boost and the car hits hyper space!! How did you get linear controll?????

Chad, I just want to say....i still love seeing this project, I remember when you first started it and have been following closely since. keep up the good work mad man!
