Tonight there will be Rotorheads all over the world reading a new bed time story to their children...

 

Done some calcs (how typical!)

How is a VE% of 118% @ 6000rpm....

PP's rock !, Very low specific fuel consumption too

 

thats not bad. koby was very proud of how much longer it could have gone. he said it could have gone another 24hours. .004mm of wear on the seals

hehehe,, I came accross this yesterday...

 

when does the far trailing plug fire? it seems that they'd have to fire all 3 plugs together or sequentially w/ a very close split in order to fire the ft plug before the squish is generated.

 

All three are fired together, NO SPLIT.

none of the race engines either from the factory or customer teams using three plug set up run ANY other way, even two plug engines run no split.

The resons have been documented many times before, but basically no split = more power, more efficiency, better faster burn. To people who say it cannot be done on turbo RE's, I have been running no split at highish boost (20psi) for a long time with no problems.

 

Looks like the 'ole SAE paper...

rice,
do can you post some of that documentation proving why no split has more power, i'm interested in seeing it. does no split have more power throughout the whole powerband, at all rpm ranges, off and on boost, part throttle and wot? or does it just have more power at certain parameters? which would allow for a more complete combustion, split or no split?

 

I found that the other day too. I want one of those motors bad. but I am sure I can't afford it. So I found a site where a guy basily bolted two 13Bs together. I was thinking about that for my 87 n/a drag car

 

When dyno tuning my car on big boost and C16, we lost 10kw to the back wheels by running zero lead/trail split and the car sounded very unhappy.

 

hmm, interesting. where are these documents you speak of, rice?

look at the icky duration

 

also makes me wish for TDR rotors,.. :-(

 

 

so how effective is a sideport ex. vs. a pp ex. when a turbo is thrown into the equation?
