I dynoed my car for the first time today. My only HP mods are a M2 aluminum intake and a pettit DP. I also have all of the reliability mods. I did these runs with a wideband. So tell me what you think. I am pretty impressed with the torque curve. It is much flatter than I had expected.

 

Your dyno curve matches mine almost exactly, I have a downpipe and RB dual-tip. You get more of a spike at transition due to your open intake, but other than that, looks almost identical. Nice #s. Throw on a cat-back (watch your boost levels) and you'll gain 15 more rwhp.

 

doubt he'll get that much rwhp w/ just a cb and no boost increase. stock cat is still the bottleneck.

 

He hit 240 rwhp with open intake and downpipe. I hit 240 rwhp with a downpipe, RB cat-back, and stock intake. I would expect a gain of at least 10 rwhp from an aftermarket exhaust, even at 10 psi.

 

I hit 242.6hp on the dyno jet with Apex'i intake, DP and Racing Beat dual tip CB. And our curves match almost perfectly Rated. Nice numbers bro. Laterz.

see what i mean.

 

I hit 260 with the mods listed in my signature. My peak HP came right at 7500 RPM with the streetport.

I am wondering...Are you running a modified ECU because man your AFR is beautiful? I need a wideband in order to get mine tuned a bit better. Also Rated R1 what kind of wideband do you have and how did you integrate it into the PFC(assuming you have one)?

 

Look very stock ECU-ish

 

wow, look how rich the stock ecu is at high rpms. From what I can see, it looks like it barely hits 11:0 to 1 at the very end of the run. Backs up Wade's runs with the wideband and the 3 mod myth being bogus is you control the boost to 11 or less psi.

Although I won't say that the "three-mod rule" is completely bogus, I can say that I ran with a CB, DP, Efini Y-pipe, and modded stock airbox with the stock ECU for six months without any problems. Car is still running strong with modified ECU 5K miles later.

 

Also makes me wonder if upper 11s is pushing it AF wise???

 

I forgot to mention that with my rebuild I got it streetported. Although I'm running so damned rich off of the stock ECU that I'm losing some serious power I'm quite sure. It's rich enough that I've had high rpm breakup a couple of times. The PFC is on the way VERY shortly!

Your graph is very simular to mine, but mine have a heavier dip after the boost spike. I hit 278.9, I had dp, mp, cat-back, F-Con and RE air filter. It wasn't running that good at that time, but I haven't dyno it ever since.
The car was running rich all the way shown on the A/F gauge and the boost spike went abit over 15psi and ever so slowly goes back to 14psi

 

I am on the stock ECU. For now, I am going to go with the 2 mod rule since it is more conservative. I have an AEM but I am still trying to learn the thing. When I install the AEM I will integrate it with a OZ DIY wideband. Thanks for the comments fellas keep them coming.

 

Rated R1, be careful with that AEM EMS unit. I have friends that own a very reputable shop specializing in Hondas, and they had all kinds of trouble trying to tune an S2K with the AEM. Hopefully it will work good for you though. Best of luck.

i was going to say the same thing...

 

so you're saying even w/ a streetported motor you were running rich w/ the stock ecu?

 

I definately can't say anything bad about the AEM ecu's because my friend is using one on his Supra and putting down 705 RWHP. His AFR is wonderful and the only problem that he has had with the ecu is the latest version of their software made the car hard to start for some reason. All he had to do was to uninstall that version and bam he was running at 2.1 Bar again. Man they are wonderful cars and I don't care what anybody says.

 

Nice #'s. I'm wondering what mine will hit.. she's stock..

 

Let me know what you get with your stock car. Do you have any mod plans for it? Where are you in NC? I have got a good friend with a black '94 touring in Raleigh.
