I think you're probably mis-reading the torque on your CL-S dyno. The peak numbers were probably reading off of the hump from the torque converter at the low-end if you ran it in SS mode from low revs. If so, that's just the torque converter and not the engine.

The more and more dynos I see for auto and 6spd V6 Accords, the more convinced that the engines do put out different power numbers...not the generic 240hp. I think the autos may be 240hp (crank), but I think that the 6spds are more along the lines of 260 crank (with premium gas). The premium gas and variable intake seem to boost the numbers of 6spds quite a bit.

I think member 'stoner' did a dyno of his bone stock 6spd and with a 15% drivetrain loss he came out with roughly 259 crank hp.

15% loss is what you'd expect on a RWD live-axle setup, like a Mustang GT or a Camaro. FWD and RWD independent suspensioned setups have more complex final drives and a little bit more parasitic loss. around 17% for a manual in most cases. Add about 5% to that for most automatics, although some are a lot worse (like the mazda 6s automatic, and some chryslers).

Another common error people make is that they take the highest and most optimistic dyno ever and then claim that to be the gold standard. in reality you should take the lowest and the highest and throw them out, and then average the rest to get the clear picture. And then there are different types of dynos... It goes on and on.

I think 250-255 is what the 6spd is putting out.

Well, maybe so. As I mentioned, 'stoner' did a dyno and used a more conservative 15% loss for his 6spd to come up with 259 crank. So 17% would make it somewhere between 260-265 crank...impressive.

Well I'm not stock anymore. I'm going to be dynoing again soon with I/E (aem v2 cai and greddy evo 2).

Tonight's track runs were VERY disappointing with these new tires. I'll post it up in the 1/4 thread.

Hey guys, i had my car dynod awhile back, and I got 225Whp/200Wtq, the only mod i had installed at the time was the AEMv2.

adding 17% to that would = 263.25 hp @ the crank, and 234 TQatC.


So, with UR dropping soon and a comptech SC, im hoping for almost 400hp!!

then i'll be hunting for some sti's, evo's, and M3's!!

Please post a dyno chart, I'd like to see where specifically the gains are at. Another member has a AEM CAI and Greedy Evo...he got 223 and 198, so yours is quite a bit higher for some reason.

Well the AEM V2 adds more power than the normal CAI and the Evo exhaust isn't going to do much if not lose a little power so that's about right...

From what SteVTEC said a while back, the variable intake does not increase the peak power of the motor..... it just fattens up the curve a little bit at lower rpms. At higher rpms (where peak power occurs), the intake manifolds are basically the same..... only at lower revs is the variable part of it affecting things. At least that's how I understand it works.

I had A stock dyno done awhile back and I put down 212.1whp and 194.6wtq on 91oct. So 250-255 Flywheel hp would be an apropriate claim.

My thoughts exactly. I mean aftermarket exhausts sound nice and all but I'm unconvicned as to the fact of their performance gains.
