Type-S pistons, Crower stg. 2a cams, no balance shafts. The yellow graph is the best with the stock cams.
The header is a stock prelude upper with a accord bottom half (it's in an EF, and this fit to get the car on the road.)



The car runs so smooth, idles like a champ and sounds great.
Gotta thank the Neptune for exemplary part-throttle behavior, and Jei @ Blacktrax for the great tune. After 24 runs (part and full throttle) the plugs came out of the engine looking like they were fresh out of the box.

 

must feel good driving that thing around

 

It's in an EF...man you can never tell what the next man has under the hood now lol.

Good stuff man

 

graph says 204 at th flywheel, is that correct or is that actually at the wheels like you say?

It's at the wheels, the reason that it says "flywheel hp" is though HP reads the same on the normal ("horsepower") display, the "flywheel torque" display takes into account torque multiplication from the gears and final drive, where the raw number ("torque") shows the actual measured torque, which in the case of this car was 925 lb-ft. Not exactly a useful number!

And that's why I used the "flywheel" HP and TQ display.

 

looking good Jesse

 

Thanks, feels good when I hit the loud pedal too. :D

 

It needs more torque.

What's the stock cammed setup? Is it 11:1CR too or it is before most of the upgrades? Does it use IABs? I am just curious becasue you managed to make a bunch more torque on the low-end using cams that supposedly have the stock idle lobes.

That's still pretty dang good for stock header. The DC is a wad better than OEM I can only imagine what a nice cutom unit would do. I made over 20whp from upgrading from the stock header to a custom one.

Thanks for sharing the plot.

It was 11:1 before too. The IAB open at roughly 4300 RPM.
The head was hot-tanked when the cams went in. I put the cams in because the head was off while the block was re-ringed due to some oil burning issues (great compression, but it drank a quart of oil per week.) You can imagine what the exhaust ports looked like before the fix because of that.

 

So do you think the gains on the low cam are from cleaning up the head? Or maybe the crower cams have JDM "stock" low cam lobes or something?

Anyway, nice graph. Time for a header!

 

do you happen to have a graph of when it was stock? I'm interested in seeing what all changed on the graph.

Well it was a JDM motor, so I already had JDM stock low-cams.

I'm sure that it was the head being cleaned.

I have a graph of when it was untuned and still had the stock cams.

Never dynoed with stock pistons. I had the Type-S put in and the balance shafts pulled out before the engine was ever put in the car.

 

do you mind posting that graph?

 

This is the engine, fresh, running a JDM P13. Stock cams versus tuned with the Crowers.

 

I need to get some cams hot damn :s
