The Revelation Posted December 21, 2005 Share Posted December 21, 2005 im wondering the same as texasz, how come you are using an sx tranny? im really curious to see if those perform better (im using the term "better" loosely). Quote Link to comment Share on other sites More sharing options...
slownrusty Posted December 21, 2005 Share Posted December 21, 2005 Very sweet motor....looking forward to seeing the numbers as well. Quote Link to comment Share on other sites More sharing options...
twistex Posted December 30, 2005 Share Posted December 30, 2005 yeh i wana see some numbers .. still i havnt found anyone who runs the ld28 block and crank combo like i did! you can run the longer rod and its safer to bore. im running 45mm sk racing carbs on mine. mine sees 8k no problem. i need to make it down to the dyno! these motors love to rev when you have a light flywheel, balanced and knife edged crank. one of the fastest reving engines i have ever seen.

v8dats Posted December 30, 2005 Share Posted December 30, 2005 that looks awesome! great job! Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted December 31, 2005 Share Posted December 31, 2005 What gas you running to cope with the 11.8:1 CR? Also are what head do you have? Thanks, it is awesome btw. Quote Link to comment Share on other sites More sharing options...
4everDATSUN Posted January 3, 2006 Share Posted January 3, 2006 looks like a p90a, shaved down quite a bit. its also got some massive ports and valves. im sure once you put that 510 cam in you hit 8k no prob. i would never trust a fram filter after seeing it opened up. a wix filter is leagues away from a fram in everyway. cut them both open sometime. what piston and bore did you end up using?

pimp1911 Posted January 3, 2006 Share Posted January 3, 2006 What gas you running to cope with the 11.8:1 CR? Also are what head do you have? Thanks, it is awesome btw. +1. I am curious as well. Race or Pump? Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted January 3, 2006 Share Posted January 3, 2006 Where's the turbo? j/k Quote Link to comment Share on other sites More sharing options...
Mack Posted January 3, 2006 Share Posted January 3, 2006 well, Ill answer for him, since Ive ridden in it and even driven it! it runs on pump gas. no additives, no BS. I think he has his total advance set to 34*, which is just about right for a fast-burn, high quench head. which, is what you would get when you shave a P90 down QUITE a bit, lol!~ Quote Link to comment Share on other sites More sharing options...
1 fast z Posted January 4, 2006 Author Share Posted January 4, 2006 PUMP 91 octane, ~34 deg Full, P90 shaved .1", DIRECT flatop with .015 Neg Deck Height. NO detonation! Wait, can that be? Well, yes IF and Only if everything is setup correctly. STOCK dia valves BTW, PORT velocity. Quote Link to comment Share on other sites More sharing options...
1 fast z Posted January 4, 2006 Author Share Posted January 4, 2006 Heres the info on the pistons from the other thread, BTW this was comparing against a stock DISHED pistons, as if I was comparing against a flat top stock piston, (P79) It comes out to 2.75 lbs total out of the recipicating mass! Ok, so I wasnt totally sattisfied by the amount of mass I had scavanged out of the 3.1 forged pistons, so I took them back to the bridgeport, and started some more work on them, there still not as light as they could be, but frankly I am just running out of time, and it takes ALOT of time to do these procedures correctly to 7 pistons. But yea got them all finished and balenced within a half a gram . Should finally be assembling this weekend! Ok, for the numbers, they are 320 grams, the pistons by them selves. Combining the pistons and pins I am right at about 150 grams lighter than a stock dished piston. thats what about 2.0 LBS out of the recipicating mass, WHOOOO HOOOOOO!!!.
