The bee hits the roller
I finally got the bee to the dyno today. After overcoming some serious headaches, we finally got a descent tune on the car. I still think we left a little on the plate, but I am happy with the results.
A little breakdown of the car....
1992 Sunburst Yellow A package (2050lbs before FFS)
2000 1.8 Engine
440cc RC Engineering Injectors
Megasquirt PNP
AEM Water Injection
I set the cam gears back to 0 deg before the dyno. I'd like to head back and play with them and see if I can get the torque up a little.
We tuned it to 11.8 on 93 octane. It was much happier into the 12s, but being that it will get abused on the track, we took the conservative route. I stopped the pulls at 7100ish rpms. I have the rev limit set for 7500 and have been known to bounce of it in the past. So running the current plot into the 7500 range should have put me in the 225-230 range.
The first plot is the final run today. The 2nd plot is an overlay of my last trip to this dyno along with today's plot. Just a little change.

I still have something going on under high vacuum, but I haven't really taken much time to find it. I will figure it out eventually. It's not causing any performance issues. It's just an annoying tick.
I am running the 115mm crank pulley with the 65mm blower pulley.

Looking good! I cant wait to see some track footage with your extra power. When does your season start up there?
Also, how do you have your WI set up? Is the AEM unit a progressive controller? What size nozzle, when do you start spraying and when do you hit full pressure? i may have to follow your setup to keep things under control on track.

Our autocross season starts next month. I am heading to VIR in two weeks. I can't wait to see how it does. The camera will be rolling!
I have the tanks and pump mounted in the trunk and the nozzle mounted where the 5th injector would normally be. I am using the smallest nozzle in the kit. I think it's 175cc.
I have the WI coming in at 3psi and is at full power at 9psi. It appears to be working really well on the dyno. Let's see how it holds together in the real world.

Did you make a plug for the 5th injector hole and drill and tap the plug for the nozzle?
Can you post up your on track WI usage when you get back from VIR? Just curious how large of a tank is required for a 20-30 session.
Thanks!

I have 2-one gallon tanks installed right now. I have the 2nd tank plumbed and ready to go but not connected. Based on my time on the dyno, I should only need one tank, but I will be ready with the 2nd if need be.
Brain...I like complication and headaches. That's as far as I am going with that statement.
