mo balls than $cents$
i know it made it to a dyno and i know what it was doin barely opened up, now let's hear it or see it putting the hurt on the dyno!devil
We dyno'ed the motor again today and it ran great but the dyno load cell had some problem and stopped reading at 3300 rpm.
It is all brand new equipment but something is not working right.
I re-adjusted the boost controller so it holds the gates closed better and the torque went way up.
It made 1346 ft # of torque at 3300 rpm.
That was with 15# of boost.
In the boat it is never loaded at that low of rpm so I had no idea it would make that much torque at that low of rpm.
It was building approximately 100 ft # of torque per 100 rpm.
I have a video and I'll upload that later.
The sparks on the first video came from the flex plate ticking the starter gear. In the boat there is an adapter plate that bolts on the flexplate to drive the transmission so it is held solid.
It'll probably be next saturday before we can hammer on it again.
Of course......I'm going run it at the boost that it did in the boat all summer..... at least !! :|err Whatever it takes to show 1800+ hp on the page. I don't have the cojones to top out the boat with this engine in it so the dyno sheet is all I have to show. devil)eek))eek) wholllllly shit! devilgrngrn
mark, are you goin all out when the dyno is fixed? devil
billy's wantin to drop his cam down some now. same train of thought was you, less wear and tear on the valvetrain. i like small cams too, my lil 5.3 cam is only 548 lift.Of course......I'm going run it at the boost that it did in the boat all summer..... at least !! :|err Whatever it takes to show 1800+ hp on the page.

A slight advantage I have on the dyno is that we're running well water through the intercooler at 55 degrees. The IAT never got over 84 degrees during the pull.
Speaking of cheap ass, this is the Lexus air conditioner evaporator core that I'm using as an intercooler core. Cost me $ 108.00 brand new. bulb
The dyno operator can't believe I'm still using the same spark plugs for the last 3 years. Same valve springs for 4 years. The cam is only .630 lift minus .025 lash, Not much there. Never even used a stud girdle. Heads are out of the box Dart 345, no money wasted on port work here either.
This LS2 COP ignition setup is something else. A guy had a scope on it while it was on the dyno to watch the spark event.
There's so much scuttlebutt on COP that the dyno operator didn't have much confidence in it over CD ignition. Now he's convinced. Still firing .035 gap at 27# boost @ 7500+ rpm.
That is the beauty of turbo systems is that trying to optimize cams, valve train and porting is of little benefit.billy's wantin to drop his cam down some now. same train of thought was you, less wear and tear on the valvetrain. i like small cams too, my lil 5.3 cam is only 548 lift.
