Hondata's peak numbers are a bit inflated relative to others because he ran his car on Church Automotive's Dynapack dyno (load-based) which reads about 10% higher than a Dynojet (inertia-based), typically a more consistent dyno type than others. In addition, he was running a velocity stack (i.e. no filter) which I bet netted him another 3-5whp. As a result, Doug's 338whp on the Dynapack would translate to only about 304whp on a Dynojet. I mentioned this in one of Doug's thread and he confirmed it. When comparing peak dyno numbers, you have to compare apples to apples because all dynos can be calibrated differently (though less so with Dynojets). Ultimately, the main comparison should be between baseline and modded numbers to determine overall gains.

Based on his (and my) experience, I believe that the max output with S/C + bolt-ons is around the 310-320whp range as the M62 is already at it's peak efficiency at 9-10psi. I'm currently at 310whp (on a Dynojet), but my water/meth injection is on the conservative side. If my car was tuned more aggressively, I'm sure I could extract another 8-10whp, but I don't think I'm willing to risk a blown motor in the event of a pump failure for such a relatively small gain.

Never say never

Yeah ) Never say never, raise your CR , use race gas or meth and youll get more than 320 ..

I'm already running water/meth (only TSX that I know of so far), but there are other options I'm considering besides raising compression...

What about cams made for the SC setup, and a higher redline? Nitrous is a consideration?

These are just questions in regards to power with the supercharger setup.

thanks guys i apprciate the help, so they make hondata for edm's do they?

And on comptech website it states you send of your ecu for a reflash and they give you a piggyback?
would this not be the route to go and if not why not?

I wanted hondata but i really dont wanna travel some serious miles to get a tune....

Oh and cams wise and redline wise what are our engine good for standard? as its only the extra stroke on the block that makes the extra .400cc the pistons are the same size as the 2.0 correct??

u mean meth injection, i mean pure alcohol run ) instead of gasoline ) octan number let to use crazy CR and power can be up to 380whp on NA engine, imagine what can be on SC.

Listen here my edm bro. The only way to use CT SC on your car is hondata dual ecu setup or aem piggyback. Check hondatas edm dealers on their website , i saw some from uk, theyll help u to tune and so on . Please no any other question like i saw something there and ive listen something here is it true or not ?

Its not recommended to push the k24 past 7500.

if u were to look at their dyno, they also used a massive velocity stack instead of Icebox or CAI. That also has an effect.

This one I am not sure I totally agree with. In stock trim, yes I agree, however there are multiple engine builds where the motor resides in a civic or older crx, and they spin the motor higher. This all entails massaging of the crank, and blueprinting of the motor and correct cam/valvetrain, but it is possible.

Read closely, DAYTA mentions that in his post.

Building it yes. But you won't be able to rev as high as the other motors. There are F20C's revving up to 11000 rpm and K20A's revving up to 10000 rpm. If you do as much work to the K24A. You will only be able to rev it up to 9000 rpm. The K24A is not meant for high revs. To get it to rev to 8000 rpm you'll need to completely build your bottom end. You can get away stock at 7500 rpm. But how long will the engine last?

no one mentions a turbo at all, wouldn't it be more efiecient then the supercharger. wouldn't it be able to make more power with the same amount of boost

OP wants turbo.

Long stroke engines isnt designed for a high rev, even honda. U can try but price is too high for that.
