Well, nothing has happened for quite some time due to lack of resources and motivation. The redheaded Italian mistress has been taking all the former and leaving me none of the latter.
Then just the other day Scotturnot contacted me about teaming up to finish both our projects at the same time and dyno them back to back, and it may just be the motivating factor that we both need to get things back on track. So this project and thread may be coming alive again soon.
Couple things I'm changing to get the engine on the dyno:
1. I've scrapped my original harness concept with all the exposed leads encased in silicone tubing and the double conduits on the manifold. It really was turning out quite ugly rather than purposeful, which had been my original intent. I'm now going to go for a minimal approach and appearance, and will try for a better balance of form as well as function, which is something I've learned from the Ferrari side. The way the old harness was turning out was probably the single largest factor that demotivated me. It really was a disappointment, so everyone feel free to jump in and tell me you told me so!
2. In order to get the engine dynoed, I'm not going to wait until a new harness is designed, built & installed. Rather, I'll just reuse my old temporary dyno harness, which has served me well for 3 dyno runs in the past and should get us past this last important milestone. Then, following the dyno session (assuming the engine survives and makes the power that I expect), I'll then transport the engine to my harness builder and he'll build a bespoke harness for it while it's sitting there in his shop.
3. I'm also going to change the COP's from the Tundra coils, with their tops exposed and poking out the cam covers, along with the exposed wiring, to bike coils, which will be hidden under the cam covers, with concealed wiring as well.
4. I may also return to the original stubby injectors (Siemens Deka's @ 44mm long) that I'd planned to use, in lieu of the longer Deka's @ 75mm which I needed in order to avoid the fuel rails fouling those big electrical conduits. With a more conventional and smaller flexible harness setup on top, it'll now fit around other obstacles, instead of vice versa. Again, I want to try to keep things tucked away and not so visible, if possible.
The cogged drive for the supercharger & all the accessories will remain - I think it's one of the highlights of this setup, and I'm really looking forward to seeing how it runs.
The only technical issue at the moment is the packaging of the two boost control solenoids and their plumbing in a visually pleasing manner. As some may recall, I'm using a dual port actuator on my supercharger bypass valve, so with the right input from the ECU it can either be used as a conventional bypass valve, or as a boost controller. I'd prefer to test this on the dyno under controlled conditions, however it's not critical to getting the overall engine on/off the dyno, so I may defer it.
So that's the long winded version of what's happened
