who cares? it was 4th and 6th overall at the 25 hours of Thunderhill, that is impressive.

high 14's is what the new Si is capable of doing. then again, there's many people i've seen that can't even break out of 15's in their ITR's... drivers, not to mention motors all vary in their performance. Obviously this guy didn't know how to drive.

You seen any in the high 14's yet?

I was reading the motorweek article about the 2006 SI versus a few cars. I think it was against the Cobalt and the Ion. It beat the cobalt but it got owned by the Saturn Supercharged Ion. The Ion ran 14 something when the civic si did a best time of 15.1......Even though it's published in an article that the SI ran 15.1 I still would not believe it ran that until I see it for myself at the track this coming spring.

Again, any proof of this? And since when does Hondata have a flash for the 06 Si?

Go to VTEC.net. There car is doing it. And Hondata is in the works on the Si on a reflash. They reflashed TOV's Si.
This is off of TOV
The 2006 Si's ECU, unfortunately, is not like the earlier K-series units. As far as we know, it is completely new. Even worse, the engine management system now incorporates both a MAP (manifold absolute pressure) and MAF (mass air flow) sensor - most likely in an effort to better control emissions. This meant that Hondata needed to not only crack the new ECU (something they seem to get quicker and quicker at), but they needed to figure out Honda's control scheme for fueling using both the MAP and MAF sensors. So far, they have been successful on one of these two tasks. Fueling has not been cracked to date, but Hondata can now control everything else - cam timing, ignition timing, rev limiters, VTEC, etc.
On our Si, Hondata managed to increase hp from 224 hub hp on our Dynapack 4000 to 231 hub hp just using a rough cam timing map and adding some ignition timing. Fuel was not altered, because at this point, it can't be. Also keep in mind that this was not a full tune as it takes quite awhile to reflash the computer at present. This 231 hub hp on our Dynapack equated to 213 whp on Sport Compact Car's Dynojet 248c (a little lower than we expected, but they had virtually nothing in the way of cooling airflow in their test center, so we'll cut them a break). We did have a little drivability issue at low rpms, but this was present before Hondata got ahold of the car, so it may have something to do with our mods and the MAF sensor. The rev limiter also was a bit harsher than stock. The good news is that Hondata now has a totally stock production Si to work with, so we expect development to proceed apace from this point onward. NOTE: Check back soon for dyno plots. ed
After our visit to the racetrack, Doug from Hondata did a little more fine tuning on the car. In particular, he played with the ignition timing a bit and found 2-3 more hp across the board. He also fixed our rev limiter issue (the rev limiter is actually encoded in several locations in the ECU maps, and you have to change them all to get the desired effect). Given what other K20s with our camshafts have made in the past, we feel that another 5-7 hp is available with full tuning (whenever that occurs). We also feel that our DC race header, while great for a basically stock car, is a little too small for our big cam setup. We hope to find another 5-8 hp with a more appropriate header.

High 13's might be a little tough for the Si right now with those mods... The reason why someone said it above was bc the 05-06 type-s can run high 13's with the same mods (I/H/E/reflash). The motors are very similar, so if they can crack that ECU then its very possible... The k20 is an awsome motor
