Furtive cazy brain thinking!  Shades of FJ24 horniness going on!

Ahem,,,,,,, can that crank be destroked to 79 mm???

Group Sc!
Oh, and nbased on the offsets on the counterweights, and less stress to block, and, a block girdle, 9500 rpm could be achieved,,,, yes,,???
Im allowed roller rocker assy, apparently, as others are using them!!!

Single TB smallest d is 56 mm, with tapered intake prior to smallest id, at the "correct" included angle!



mmm the crank is 85 mm from Nissan can it be destroked that far don't know ,,, as for the stress on the block we run 94 mm cranks in RBs to 8500 with 30psi making 1000hp ,so i dont think the block will be to strest at 350hp  it would be better with a builet crank with f c w 

the hardest thing to control is the valve at rpm ,the springs have a very hard time with 620lift and 8000 ,its not so bad with titanium valves but 47mm ss is very heavy and hard to control 

the f wheel was made by les and is 4.5kg and the AP twin plate race unit is just over 2kg
  with 89 stroke and 90 mm bore it will have mad responce  ,,,11.1 comp  and light rods and pistons i think it will be fast

So Pete this last engine this is the last engine for a customer right? You are still going to slowly work on the NC26 hybrid thing for yourself right?

Some "overnight parts from Japan".

Kameari 50mm big port manifold and an original Tomei vernier cam gear still in original box and plastic from the 80's.

Hey Pete.

Sorry to hear you're giving it up for a living, but them's the breaks. Let me know if you want to have a go at working on locomotive engines....plenty of work at our place.

Cheers

Jamo

you were telling me when you came around there wasnt enough money in it. Shame, cos you obviously have massive amounts of knowledge and skill in what you do! Im sure the TAFE in traralgon would be great for you to teach at :).

I'm sad i don't get to see it all in bits before it gets assembled  :(

That and the fact that I read all the zed forums and all the  L series engine building books and i still cant provide any worthwhile input after years of research :-X

I'm with you on that one Jake. I'm no newbie to Datto's or engineering.
Which is why I laugh so much when these "text book mechanics", argue with or try and discredit builders like Peter.  ::)
