Oh, that reminds me.....did the engine run backwards during the spin Duncan?

what a very interesting question.....there were 2 spins both at the same place and for the same reason, both were full 360 and the engine kept running both times. But now you mention it the knock started straight after the 2nd spin. I wonder how many g i pulled, wish I had data logging. Its also possible (but unlikely since I didn't notice) that I gave it an overrev when I got going again.

but frankly given the newness of the engine and the skills of the builder I suspect an assembly problem.

Bearing clearances? yep although I was surprised to hear that standard bearings were OK on a 100k engine. All according to the engine shop I didn't check their measurements.

Ring clearances are a bit looser than nissan spec we have to run standard piston and bore and after a hone it was a little looser, I didn't keep the exact figures.

Will next time tho :D

Ah huh, lotsa G, and then you gave it plenty in first gear to get going. It didn't hit the rev limiter by any chance?

:D cheers :D

lol I would prefer to leave it to the experts and stick to driving :O sadly life has not given me that choice I know far more than I ever wanted to about the inside of these engines ;)

If in fact it is dead that would be 3 RB engines killed by me in 5 years..... :idea: now there is a poll lol

    • I hope it's actually possible. This is a write off in insurance world.
    • Yup. 2-way with shallow ramp angles. Still works.
    • That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together
    • I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain. 
    • OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
