Here is a dyno plot I found from Circuit Concepts:

It appears they are quoting a 58 horsepower gain. I am very interested in seeing that.

ya i'll believe 58hp when i see it. im callin bs on cams bringing a 58hp gain

Even if it's 1/3rd that, it's still sick gains for a NA car.

One thing we need to look at is the fact that the graphs are 2 years apart. Meaning the first graph was probably the stock form of the car and the second graph is probably will full bolt ons, tune, and the cams.

I honestly think with full bolt ons, a tune, vvel unlocked, and cams we could POSSIBLY get an extra 50-60 whp combined.

I don't see it being completely out of the question.

It's also with their high compression pistons and upgraded rods . I asked jun about these gains.

So some really funny things to point out.
As I'm reading the numbers up top it looks like there stock factory car was putting down numbers our full bolton cars do 312 I don't think is right and it looked like the TQ was 229 damn that's low. And then the new numbers holly ****. 373hp and 272 TQ huge gains for just cams. Look at there air fuel% aka stock it was 14.9 then after it was -9.1 something is off. I duno I don't read Japanese but my friend does and I'm gonna get to the bottom of this. Lol.

no i'm not splicing together the original image. deal with it :p

Bear in mind that chart is in metric hp (.986 hp per ps), and also looks to read high.


Gains in percentages are far more telling than raw gain numbers.


I would also generally discredit any comparison that looks at runs that far apart.

Also, trollolololololol at vastly different air pressures.

the % error column still makes no sense to me, but that's the literal translation of it. i dunno.

also funny: the "rated" on the 2012 run is up to 300? wtf :p somebody has a typo!

Torque is in Nm not lbft in that chart -- also thats some sort of error margin not AFR.
