i hate you.. i think im gonna wait till i move Brian and get my car up there so you and KDR can hook me up.. even if i have to sell my soul

Project86... I deserve the hate... :)

There is still really no good update here, except that the new motor has about 12 dyno miles on it and we have done runs first with the old setup and then with the new plenum. That showed a 28 whp gain at peak power over the same run done immediately beforehand with the old setup. Again, these are runs done on a newly rebuilt motor and the seals have not bedded in yet. So, the absolute numbers are not valid, but the differences are. I hope that's clearly said? Here's a quick video of the motor with the new plenum, but not the new headers. Sounds pretty good to me.

The NEW HEADERS ARE INSTALLED and we are going to run it again this afternoon and see what difference the new headers make. Logan thinks 20 ft pounds, which would be awesome. I will post up something tonight or tomorrow.

That is all.

chibikougan... Walking around with one for months now. :)

They still haven't gotten it back on the dyno, but its scheduled for tomorrow afternoon.

What are you running for apex seals and injectors?? if you dont mind me asking :) and also... im gonna need one of those uim when i do my 20B build haha.

diabolical1 03-18-2011 07:25 PM

a 28 hp increase over stock? Gordon, my hat goes off to you and your fabricator-guy. that is awesome. how did the torque curves compare?

i can only imagine when the motor is fully broken in and the seals are bedded. do you plan to take the Defined header back off just to compare bedded versus non-bedded, or will you simply compare the differences with the Defined header?

not to speak out of turn, but i believe he's running a single set of Injector Dynamics 1000s (i.e. no secondaries). i have no idea what apex seals though.

Set of ID 1000's, and the idle L are rock solid, no wandering... I love those injectors so much.

and it's not a torque curve so much as a torque plateau. Carries all the way, I was impressed when I saw it.

project86 03-19-2011 11:05 AM

so hes only running 3 injectors then? geez maybe i should think about doing it that way... i dunno... convince me. :)

TitaniumTT 03-19-2011 11:53 AM

There is no better injector than ID. You can't go wrong. Tuning would be easier, no staging to woory about. Simpler installation, one fuel rail..... why double your chance of leaksl injectors failing etc etc? ID or nothing for me from now on

project86 03-19-2011 06:57 PM

im convinced. also... i love you?

gmonsen 03-21-2011 02:02 AM

Cheeesh... You guys need to get a room. I'm not doing more runs taking things on or off until after Deals Gap. I love the Injector Dynamics injectors. (Paul Yaw/Yawpower) I can't remember if I made the main point, which is that instead of a single pinhole squirting fuel, that single point branches into 6, like the ribs of an open umbrella, so for X amount of fuel coming out, that is divided by 6 at the chamber and so it atomizes way more efficiently. And Brian is right, the single injectors, whether 1000, 1600 or 2000cc are far easier to tune and my moto has been to go fir simplicity of everything about the motor.

I hope to have something to add tomorrow.

^^this is helpful

helghast7 03-23-2011 08:07 PM

yea i need to pick me up some ID's when i redo my fuel setup, but ill worry about that when i get there

gmonsen 03-24-2011 04:31 PM

I'll tell you, they make a difference. Very easy to tune.
