LSD will help some because of the power difference though. The other thing that was brought up was the new method of representing the HP/TQ numbers. So many manufacturers were bloating their HP numbers that they introduced a new method. Honda has used these "new methods" as their way to report HP/TQ #'s more realistically. I only know of honda/lexus and a few other manufacturers that have used this for their 06 cars so far. #'s are going to look lower because of this new rating, but I still know what you mean. With other turbo cars out there, why not try to run the race? But you and I both know that a turbo on the SI would blow the doors off the SRT 4, especially with the LSD.

The question is why not? There will be so much aftermarket support that it doesn't matter. The Civic has traditionally sold well enough, so it might be more profitable to not install more parts (increasing cost) and have more sales.

I found the release info

"*For 2006, Honda is complying with the new SAE standard for measuring horsepower and torque, SAE net (Rev 8/04). This new method slightly reduces a vehicle's horsepower rating and torque due to more stringent testing procedures. Many manufacturers are still using the older standard of measurement. Horsepower and torque can only be fairly compared if both vehicles were calculated using the same SAE standard."

vtec.net just reported that a broken in SI (3,500 miles) just got 208 hp at the hubs on a dynopack fully stock and 218 at the hubs with the airbox removed!!! Great numbers

UPDATE (21:35, 14.Sept.05): I just got a call from Shawn and today another 2006 Civic Si (preproduction, of course) was tested on his dyno. This one had 3500 miles because it had been driven cross country from Michigan. Obviously, the break-in mileage paid off because this car put down 209hp, in a fully stock configuration. With the airbox cover removed, the number jumped to 218hp. Shawn is not near a computer at the moment, so we don't have the dyno plots, and the car isn't ours, so we may not even be able to post the plots, but it's clear that our car isn't a fluke, at least amongst pre-production Civic Si's. jp

Here it is:

The K-series Strikes Again

The 2006 Civic Si's K20Z3 engine is one more member of the highly exalted K-series lineup. Combining elements from a variety of other K-series engines (K20A2 style head, Euro-R RBC intake manifold, K20A3 style balance shaft, K20Z1 style camshafts, etc.), it exhibits a smooth, refined demeanor along with a typical Honda high rpm rush of power, and a typical Honda VTEC dip as well.

While nothing leads us to believe that the K20Z3 won't be just as capable in the aftermarket as other K-series engines, it does face the hurdle of a completely new ECU and drivebywire, so modifications may be a little more difficult (we'll be the first to tell you in our project car chronicles).

In the case of our particular example, the gains may be even tougher still. Take a look at the dyno results.


The lowest curve, 197.9 hub hp, was recorded in completely stock trim after a few runs. We think this is more representative of what our car will do. The next run, 204 hub hp, was recorded with a little cool down. Note that the biggest difference occurs from 7500 rpm on up. The final run of 209 hp was recorded with the airbox cover off (note the bottom end losses). While the car gets much noisier and loses the refined growl of the stock intake system, the 5+ hp gain indicates that an intake system will probably be able to pick up some noticeable power (do not drive with the cover off, with the hood closed, you'll kill power by ingesting hot air from the engine bay).

Now take a look at the AF ratios. Note how smooth they are. Also note that they are relatively close to the optimal range of 12.5-13:1. Finally, note that on most runs, with the exception of our stock 204 hp run, that the AFR goes very rich after 7000-7500 rpm.


We think there are a couple factors at play here. First of all, either Honda has underrated the new K20Z3, or our hand-built preproduction motor has benefitted from the exacting specifications used during the build process. On the same dyno, a stock 05 RSX (rated at 210 hp on the old system) will put down around 185 hub hp. The best one we ever did (another preproduction car) put down 190 hub hp. Given how strict the new ratings systems are, we suspect our Si is extra healthy, but we'll wait to see what other gains we get, and what production cars do. If you live in SoCal, we'll do free dynos for the first 3 production Si's that come in (310-518-4966).

The fact that the AF ratio goes rich at high rpm on virtually all runs tells us that the K20Z3 is either very temp sensitive, very knock sensitive, or both. The very flat AF curve is also unusual for a factory car (Honda or otherwise), which is one reason why we suspect a little tweaking.

Stay tuned as we begin pulling the car apart and looking for more power.

HP definatly underrated

Being under rated on hp is ok, it will keep those insurance rates down, I heard if the car has a rating of over 200hp insurance rates are higher be higher. The Si really has more than 200hp. This under rating is to benifit us the consumer.
