Comptech Dynos up
http://solar.innercite.com/comptech/tsxdyno.html
there is a dyno for headers, icebox, and catback and also alltogether
gains arent as good as i expected them to be

Weak? No. Pathetic? Yes! Was hoping it would respond to bolt on's a little better. Guess you cant win them all.....

Re: Comptech Dynos up (uncivical)
Guys, this means one thing, and I was suspecting it, this engine is already a very hot NA engine, and though gains can be made, they will not be very significant, because Honda has already built it with very sharp specs.
It says that the K24A2 is a very well-born engine.

Let's see what some Hytech cams will do to that sucker.
Shawn Church from TOV said the K motors were hella tunable, the RSX-S being the prime example.

Re: (MAFA)
Wow, there might not be any real gains down low, but check out what the peak HP is at 7,000 versus what the baseline was. Thats sure to make it worthwhile to go passed 6,500. Im impressed with the peak numbers, and the torque isnt that bad. Also, I wonder what it would do with a lower VTEC crossover point.

But the price that Comptech charges for their products...I do not believe it is worth it. Perhaps if they reprogrammed the ECU with all the new improvements, they could capitalize on their gains.
It's not like the impressive 10-15 header gains Comptech made on the J motors.

Re: Comptech Dynos up (Inspires)
Yea, your right that its not worth it at that price, but for just an intake, header and exhuast (especially on the new K-series that have awesome headers to begin with) those are some good numbers. 191whp is nothing to sneeze at. Dont S2000's dyno at around 200whp? But judging by the dyno, it looks like the primary lobe is running out of steam and losing power by the time the secondary lobe kicks in.

Don't compare apples with oranges. The J series had more potential for tuning than the K24A2 does. The TSX engine is already more tuned than the TL-S engine, so it is not surprising the gains are lower. Also, you are talking about gains on a 6 cylinder compared to a 4 cylinder. If both systems were to yield the exact same gains, that would mean the 4 cylinder system would be close to 33% more efficient than that of the V6.

Re: (MAFA)
Maybe if I had not seen John of Hytech flagrantly insult all Honda owners on Honda-tech I'd be interested 
Still, I have to admit they make good stuff.

Re: Comptech Dynos up (TurbothisLS)
Waiting for Hytech's products. Hytech took the RSX-S engine and built a screamer. Don't give me any of this "the K24 is already heavily tuned BS"

Re: Comptech Dynos up (MAFA)
Whatever, MAFA, but it's a lot easier to build the RSX engine because it's a near-square engine, so it's a lot easier to get revs out of it. IT IS NOT THE CASE WITH THE K24. You cannot safely rev this engine past 7500rpm. At 7400rpm, the piston speeds are already at least as fast as that of an S2000.

Re: Comptech Dynos up (sauceman)
What is the rod/stroke on this engine? What is the length of the stroke? The bigger the stroke, the lower the redline, but most people dont realize that R/S doesnt directly affect how high you can rev, only where peak power is determined. Im sure im preaching to the choir on this one, though.

Re: Comptech Dynos up (notstock93)
Bore: 87mm
Stroke: 99mm
Name me an engine with a 99mm stroke that can rev over 7500rpm day in day out while retaining a decent durability and reliability.

Nevertheless, their RSX finished pretty far back in the pack in a recent national magazine comparison, right?
Perhaps some of the competition they were up against really wasn't a fair comparison.

I think the ECU is the key, as you've said.
Even if we are not going to be able to rev the 2.4 TSX motor like the 2.0 RSX motor, a Hondata will maximise the performance of all the bolt ons.
I don't think there's going to be a cheap way to go too much over 200 HP in the 2.4 K motor.

Ok. Now we know that a gain of hp with bolt-ons usually occurs by moving the peak hp up higher in the revs. You can't do this well with the TSX, so you are pretty much limited to gaining power by increasing torque which will in turn increase your hp figures at the same given rpm.
This is one factor that limits your hp gains, because for every pound foot of torque gained, there is a lower hp increase at 7500rpm than if it were, say at 8500 rpm.
Now the K24A2 already has high compression, and a very good, free-flowing head to it, plus headers that seem to be pretty serious also. This means quite frankly that you just cannot expect much bigger gains than Comptech, it 's justthat way.
Like George Knighton said, the best gains should come through ECU tuning, but even then, since the engine is not safe over 7500rpm, do not expect even to reach a 20 hp gain through the ECU. Like he said, there will not be any cheap power made with this engine.
You want a good bang, your only choice is FI.
