P1000 White Lightning Build

That's exactly what would be expected from 72 to 94.

If you're at 94 hp and 55% IPW, fuel is definitely not an issue. Even E85 would be under 95% IPW at 120hp with boost referenced fuel pressure.

All I have is the base timing, 15° BTDC at idle, and can add or subtract from whatever stock advance it adds. The dyno liked about 5 degrees up top added on a stock machine with the PCV. Still need to verify the 55% but pretty sure thats close. The fuel pump free flows, per the book, a minimum of 33.75 GPH. I believe 120hp calls for around 17 but would like to have 3 times that when possible.

What did the stock machine make stock timing and plus 5?

I believe it was 9 total at .9 and 2-5 degrees added through the rpm range. Think timing was good for 3 hp. @joeymt33 might remember exacts. Too many beers since then.

9 degrees of total timing? AFR probe before or after the catalyst?

9hp total and 3 of that was timing. O2 in the stock location before the cat.

 

[snuffnwhisky]

That was my machine stock to joeys with the pcv and autotune. Think theres info on all of it in joeys build thread way back. Didnt make any pulls with no fuel and only timing.

Yall sure do know motors. All that stuff is over my head. lol

Yep bla bla flux capacitor

 

[ohanacreek]

If @snuffnwhisky makes instructions for a flux capacitor I'm using them.

I need a Mr. Fusion. We average 2-3 bags of garbage a day. Ill never run out of fuel lol

Looks like we have a cylinder head upgrade from the Talon! Possibly a cam upgrade too.

Injector and throttle body also. Fuel pump is probably bigger too. Looks like they were prepping it for a turbo or SC.

I forgot about those and came back here to edit. You beat me to it.

Retaining 10:1 compression definitely looks like they plan on forced induction.

Yep. And piston oil squirters. Dont know if the pioneer had those.

Yes, exactly. There is a list of things that they did that are NOT NA build optimum. Adding piston squirters to an off-road, DRY SUMP engine is definitely anti-NA.

"intake lift is increased by 2.5mm, with 25 degrees longer duration, while exhaust lift is increased by 2.2mm, with duration a full 45 degrees longer." Is that the difference between the pioneer and African Twin cam? If not, this is a Talon specific cam. I don't think it's possible to add 45 degrees exhaust timing to the African so it must be a reference to the Pioneer cam.

Yea i saw that just a while ago and was looking for my specs on the africa cam. Got a shop manual for it at work. Trying to see if i have it here at home. Thats a lot of exhaust duration to add unless your planning a turbo also.

An early EVO is hard as hell on valvetrain parts with forced induction/high specific output, so I would wager that most of that extra duration is later EVC compared to the Pioneer that probably has a very early EVC to reduce exhaust reversion/noise. I would also speculate that the extra intake duration is mostly IVO and the IVC is virtually identical to the African cam.

Emissions are probably a big factor for the relatively low output of the Pioneer and the huge jump in exhaust duration between the two cams. My thinking is based on the "carbon tax" they impose on us via manufacturers for gross emission output (or, more simply, stupid bulls*** breathing tax.) Manufacturers do a lot of things that don't appear to make sense, but do when you look at the big picture.

Africa:
Intake
opens at 1 mm (0.04 in) lift 5° BTDC
closes at 1 mm (0.04 in) lift 40° ABDC
Exhaust
opens at 1 mm (0.04 in) lift 40° BBDC
closes at 1 mm (0.04 in) lift 5° ATDC

Cam lobe height
IN 41.240 – 41.480
EX 41.531 – 41.771

I believe I measure 1.7 rocker ratio.

Pioneer

Intake valve opens at 1 mm (0.04 in) lift 5° BTDC
Intake valve closes at 1 mm (0.04 in) lift 25° ABDC
Exhaust valve opens at 1 mm (0.04 in) lift 20° BBDC
Exhaust valve closes at 1 mm (0.04 in) lift -10° ATDC

Cam lobe height
IN 39.340 - 39.580
EX 39. 798 - 40.038

 

[snuffnwhisky]

Should be +35 deg on exhaust and +15 on intake at 1mm difference. Would have to get the events of the new cam to really see. Might be 45 and 25 at advertised duration. Think I might have a little more lift.

So it has to be a Talon specific cam.

Awesome info!
