    Nice looking stuff! Can't wait to see air boxes and plumbing.

    Hmmmm....
    Even at 380 HP we get (x-Rifledriver) swizzle sticks.
    Yeah...
    dump more hp into it. Dump more money in it. Might be able to coax 600hp out of it.
    Yeah...
    Make swizzle sticks...

    or maybe just buy a vette and thrash the living *** out of it. No swizzle sticks.

    That said however - I have full appreciation for your workmanship!

    A few years ago, didn't one of our valued members from Australian have some special "quill shafts" made out of spring steel, that would twist (in torsion) up to something like 270 degrees and return to their original shape? Seems like that would absorb shock loads and prevent damage...etc...

    Much rather have a 750hp Tr than a Zr1. Been there on both cars. Ferrari holds the cool edge

    Yes one cam position sensor, converting the engine to coil on plug ignition so I need a sync pulse. I also blocked the oil which would normally feed the vacuum pump.

    My cousin 3D printed these covers to replace the distributor caps and wires now that the engine is coil near plug. Will post video of it running soon once I figure out how to get it on YouTube.

    Thx James, We also made little adapters to twist the cover so the text was level. Now we'll make real pieces in Al.

    For around 80-100k investment you get North of 1000hp. I am currently trying to to do it one more time but it may not happen.
    Love the TR with 750-1000 hp. It is what belongs in such a radical looking car.

    Just built a new ECU (GEN4) to run 12 cylinders, when I Dyno'd it before with turbos I used two of our GEN3 ECUs, one per bank. Just wanted to see if it would run on the new box w/o the turbos. Next I'm gonna change the belts and retard the intake cam 6 degrees, the turbos will like that. Then to Newmans to put his billet diff in then I'll put it all into the car. Having the turbo stuff painted now.

    Finally got cams degree'd, and new belts and water pump seal installed. Highly recommend the Hill Engineering belt tensioners, pieces of art and a 1/2 pound lighter, haha.... Fired the engine up with my new BigStuff3 GEN4 ECU which can handle 12 cylinders now. ECU also uses 2 Bosch LSU4.9 WBO2s for closed loop operation on each bank. In the process in swapping in a Newman diff and new Modena mainshaft and gears. Changed the gear ratios slightly to give a better gear drop ratio for 60-120 mph blasts. Gears are stronger 28 degree and mainshaft is now fine spline. More on this later...

    Hi Turbo Joe,
    Hope you are well. Yes it is, but the actual plumbing for the car won't fit on the Dyno. In the car plumbing, the turbos are mounted to a chrome moly tube frame that bolts to the gear housing, this would all interfere with the Dyno bell hosing. My primary reason to run the engine on a Dyno cart was to make sure it still ran after I degree'd the cams and changed belts. Once the diff and new gears are put in, it'll all go into the car. I kept the original engine/trans all intact so my plan is to make the new engine/gear housing/trans a separate module to just plug in. The fuel pumps and fans will use solid state relays mounted to the new engine.

    don´t move the relays to the engine, too much vibrations, better left or right from the engine

    and yes john, I´m fine, until now no covid and in 11 days again going to thailand - if I will have a negative covid test

    Safe travels, the relays are solid state so the vibration won't bother them...
