Dyno Power Curve for Bone Stock FD

Hi!

Does someone have or know where to find a power curve for a bone stock FD?
I would be very intrested in having a look at it. Preferably a power curve for an automatic but I suspect that is asking for too much. (And I'm guessing they are quite alike...)

Thanks!

I have seen them posted in the 3rd gen section from when people have dyno tuned but rarely is it a bone stock car. You might want to use the Search functionality if you wish to research.

Here are a set of my car with only the stock downpipe replaced. (One might argue this makes it nearly equal to the JDM cars without a ternary catalyst). It is a manual transmission. I believe an auto will transition at lower RPM.

You can see how intake manifold heat soak caused power loss from one run to the next.

dgeesaman: Thanks! It will do. The runs were in 4th gear, right?
Did you have any fans blowing air at the car during the runs? If not the heat soak is understandable.
And yes, the Auto revs lower. The reason for its lower power output I guess.

Yes the heat soak was due to inadequate fans blowing into the engine bay.

Yeah, very few people dyno a bone stock car. Most people use the dyno to tune a modified car.

Very few people have a bone stock car with a precat that isn't half melted shut.

I have a precat with under 1k miles on it and I have never seen anyone who has a use for it. Maybe with the move of the FD to A stock in autocross I can find someone to use it(?)
