Where to start.... well the good news is that the motor finally ran today, and Mitch got the maps dialed in. John Brady stopped by this evening, just in time to watch some of the runs and help us pull the plugs. It was good to finally meet him.
The bad news is that the used 550cc injectors I had procured awhile back and had cleaned and flow tested were not working, nor were the new set that the injector cleaner/tester sold me, and in fact the new injectors were nowhere near 550cc, and were probably more like 450-470cc/min. Mitch had to add 30% more fuel to that bank of injectors just to get them to balance out with the others, and even then we found one injector that never would fire correctly. Complete junk and a waste of money is about the nicest thing I can say about them.
Bruce Holt of Five-o-Motorsports, true to his word, shipped me (4) pristine looking 460cc/min injectors yesterday which arrived this morning at 0900, plus I had another set of eBay specials which have not been cleaned or tested, so we swapped out the whole batch of junk 550cc/min injectors, and replaced them with the 460's and the engine ran fine. The only problem is that the whole da*n supercharger assembly had to come off, and apart, in order to get at the fuel rail on the right bank of cylinders.
So after a complete disassembly of the supercharger & intake system, a changeout of all the injectors, and a reassembly of the supercharger and intake, we fired it up, Mitch got the maps setup and we made a few pulls.
Here's a couple of videos - we didn't make any printouts just yet, but IIRC, we're running around 360-370 lb-ft of torque and we saw around 350 BHP at 5200 and 15psi of boost, and only 13 degrees of very retarded timing (to avoid detonation). No methanol/water injection just yet. Tomorrow, we hope to get the M/W injection setup, and crank in some more timing to see what sort of power we can get out of it. Then we'll put the new cams in and see what they do for the motor.
So without further adieu, here's what a 2.2l Opcon/Autorotor supercharged 1UZ motor running from an AEM looks & sounds like. This is with Tundra COP's, fully crank triggered ignition (running in waste spark mode), and fully sequential (single cam sync trigger signal from the left engine bank) EFI with 460cc/min injectors.
Internal mods to the motor are SS valves, new seats & guides, heads are mildly ported, Wiseco forged pistons, running around 9.5:1 compression on stock rods. Everything balanced, and heat shield coatings on piston crowns, with oil cling coatings on the bearings, etc.:
