Taing it to the next level- 3.6 engine build

I understand a dyno is used to tune the engine on a controlled environment , and that it won't show some of the engine attributes like acceleration, driveability etc... But it sure helps

Btw no need for aggressiveness I have no idea what asking for dyno numbers has anything to do with anybody getting beat or beating themselves.
Tell me if dynos don't tell all why would you own 3

The dyno has its place. The issue is most people have no idea how to read, or comprehend a dyno plot. When I hand a graph to someone and I watch their eyes go straight to peak power output, I shake my head and generally become disgusted immediately.

When my wife was Land Speed Racing her 996 the dyno kept her away from 3 records on two different occasions. I made changes to the car that I knew made it faster from the way it drove, and responded. The car LOST 6 HP at peak with these settings, but she smashed all those records in one weekend after that was done. They all still stand today.

I make more average power as an overall goal. Its really easy to make peak numbers, but increasing power at every RPM point is not a simple task.

Retaining drivability, longevity, reliability, and fuel economy while making more power is the big challenge. Rick will find that his MPG has increased by at least 3-4 MPG as long as he can keep his foot out of it, I have had some of these increase more than that.

When Jake and I first started talking about engine builds he was very up front that the engine would make great power but would be very drivable. This car is not my daily driver however I want it to be civil enough to be so if need be. I did not want to sacrifice daily driving comfort for peak horsepower just for bragging rights. To be honest I am just as curious to see the dyno figures as anyone else but I'm more curious to see the torque figures and at what rpm's . My butt dyno tells me the torque curve will have a nice linear curve because it is very strong from idle right up to 7000 rpm's that's as high as I have spun her being new. I'm also not planning on spinning her much past 7k anyway there just is no reason to do so. When I say she's a beast that is not to imply hard to drive or finicky she's a beast because of the power curve idle on up. Plus that exhaust sound ! In regards to Jakes comment about mpg's I don't see how I'll be able to keep my foot out of it

....Yes, this battery is a direct replacement for the OEM battery.

Plug and play.

Easy as pie.

I bought it from the factory directly from this web page:

NSB-AGM94R (L4) Battery****| NorthStar Battery

Highly recommended.

You are experiencing the all around higher average HP and Torque that I spoke about earlier in this thread.

To gain this takes more than bolting parts on, we have to machine them into submission, and set things up in a particular fashion. I can easily dial the lobe separation of those cams in differently, and radically effect the power band and torque curve without changing the first part.

Thats the difference between something thats truly developed, and "built", rather than something thats just bolted together.

I prefer "built" over "bought" any day.

I love this thread....keep it coming. It is almost better than sex. Jake, I think you are about to get a new build client.

The line gets longer every week.... Added two more builds to the list this week :-)
