Hi EK9.org peeps.
Had another EK9 on the rollers today, It was Jimbob's with a B18c
SPEC
Had a few issues in preparation in the morning, nothing alot of well place elbow grease couldnt sort out
Damn you white oil filter! ).gif ":)) :))")
lol
Anyway, heres the results, and some comparisons for you guys. I'll edit the thread at a later date and add pics of Jimbobs EK9 into the thread. We'll be doing some more work on the map at some-point to smooth certain parts out with a little more time...
This is wheel hp. Modifications list to come later.
This is comparing before the VTEC poing was lowered after part throttle vs the final passes. Notice the 50hp jump in HP. heh, it'd be a bit TOO wild like that for the street. JB decided upon a fairly smooth transition for now.
JBs vs. a well tuned EK9 with cams IHE.
JBs vs. a totally stock EK9
Im sure thisll give you a good idea of the power diffeences a B18'd EK9 can have compared to the B16b. Im sure JB will post up his thoughts and feelings on the tune or the B18c engine setup in general. Later peeps.

ADDED 04/03/09 - Rundown Losses. And smoothed vs. non smoothed.
Theres always much confusion on this and many different opinions of how accurate bhp dyno reading are.
Fact is its very rare to lose 40hp in the drivetrain of a FWD all-motor car. generally you'll see losses of 10-30hp dependand on a few things from health of the box, oil being used, driveshafts/front bearings being fine and alignment being good. All of this can increase drag on the drivetrain.
Theres a few ways the BHP figure is calculated. DD dynos for example used to just use a database of losses and use these to add the BHP, they do now have a run-down test too which is 'better'
How does it work?... well, on a dynojet for example, it knows how long the rollers take to slow down on their own, then it looks at the drag on the gearbox and calculates the negative HP then adds this on to the whp measurement. Tracking etc can throw this reading waay out, or if the operator isnt holding the wheel straight then this can throw the reading waay off. Unscrupulous operators may use that to mislead their customers. When you, thats why most good tuners concentrate on WHP. The best thing about the run-down tests and negative HP is that I could test different gearbox oils and compare the difference in losses. The Dynojets also have a resolution of one hundredth of 1hp. and during runs its repeatable within half a horse-power! Thats how accurate the DJs are!
I didnt do a rundown test on the final run of JBs car but heres a run that made 2-3hp less than the final run but shows the horse-power at the engine! There is a loss of 12-14hp. on JBs gearbox. This loss will be the same on his final dynorun of 198whp. = 212bhp.

Rite guyâs sorry for the late reply, I have been out playing all day!
I cant explain to you guyâs how different my 9 feels now, it feels like a totally different car!
The only way I can explain is my 9 before hand was quite a jerky car to drive both on & off the throttle & now it jus feels like im driving a sheet of silk!
The difference in power is f***ing awesome, no matter what gear im in I just put my foot down & it starts to pull like a train right through the rev range!
It feels so much faster & smother now, im just loving it!
If anyone ask's the question is the B18 worth it or not then i welcome anyone to come drive my car, because it will defo answer there question for them! LOL
I have to say a massive thanks to WILL for tuning my car!
Watching him tuning my car I renamed him the MAD SCEINTIST, he just knows too much! LOL
If anyone wants there Honda tuning I would advice everyone to go see WILL, the guy is a legend!
All in all I just cant believe the power WILL got out of my 9 & I just cant stress enough how different my car drives now!
Once agen a MASSIVE THANKS to Will
