OK guys, I decided to get Hondata and I just got my car dynoed yesterday at Zero Factory in Torrence. Right next building from Erick's Racing. I ran before and after dyno and I did see differences between two setup. There has been a lot of mixed review about it but here is my personal feeling about Hondata.

First off, for those of you guys with I/H/E worried about gaining more power with Hondata, it's working. I don't have header in my car yet but I was able to make 161WHP with ebay intake and custom 2.25" crush bent pipe with SPW NI style muffler.

And then the owner of Zero Factory "Oshimo" just wanted to play with Iceman intake. So we decided to remove my ebay intake and install Iceman intake in verticle position. Then we went for quick run and My jaw just dropped to the floor. Because I saw additional 4 ~ 5 HP from the begining of the RPM to the MAX. I couldn't believe how much more gain I got from Iceman intake.

With Iceman intake my best HP was at around 167.2. BTW this chart only shows "Speed vs. HP" only and no torque curve. I might go to different dyno place later to make sure that what I have with current setup.

I called Iceman and talking to Andy to findout whether they have intake system for our car or not but they don't have one for our car yet. But he offered me to come by and make something out of their part bin to see if he can build one. When I have find my self a free time later I'll definitely visit Iceman for testing my Si.

Also, Oshimo made a comment about the intake pipe which he thinks tappered pipe works best with Honda engines. He said it's very important to have that kind of piping. I don't think AEM or DC has that shape on their pipe I think.

Oh I almost forgot about the real driveability with Hondata. I got 0 ~ 60mph in 6.9 second with terrible wheel hop. I was using Gtechpro and I used to get 7.5 sec without Hondata. Most of the gains are coming from having extra 1000rpm. Some how my limiter kicked in around 8100rpm but according to Hondata it's around 7700rpm.

On my butt dyno, I didn't see any significant gain up to 5000rpm. I noticed little bit of power surge after 5000rpm. I was hoping to see some more lowend torque but I wasn't too impressed with their overall performance of the Hondata. I also didn't see better throttle response like others either. It could be just me or my car is little different than other Hondat Si in this forum.



All the number that show on this dyno is not SAE corected number so you have to multiply by 1.15 to get the right HP.

I thought I just wanted to share this dyno with all the members in this forum. Here is blown up version of my dyno. Thanks
