hi everybody, i am very concerned about my ek9, at the moment i have a custom exaust and a mugen air box. i thought id take my car down to the rolling road and see what bhp i have got. they did 3 runs and the power was 164bhp which is crap. i dont know why my car has lost horsepower there are no lights on or anything.

does anybody know what could be wrong with my car or what problems it might have....??

thanks Jordan
 
very few ek9 make the claimed 185, your figure does sound low especially with mugen airbox, exhaust shouldnt cause them losses but dynos can be inaccurate, whats mileage on your car, condition (compression test), how do you look after it etc etc ?
 
Is it measured at the flywheel or wheels?
On the wheels that would be about right... a stock EK9 makes late 150 to early 160 horsepowers at the wheels.

Despite what the dyno says, how does your car performs on the road?? Have you raced against other EK9s and you were slower? Did you make time measurement to see if you are loosing time indeed?? If not, then don't make rushed conclusions by relying on the inaccurate dynos just because it says 164 bhp. I would not give a **** if the dyno was saying 100 bhp but the car was hell fast!! :nice:
 
hi the car is ok it is in good condition, im not to sure about the compression tho because i dont really know much about that. my car still feels quick because my mate has a intergra dc2 jdm and he had his dyno'd and it came out as 192bhp but when we race there is not that much in it.
it is a 164bhp at the fly wheel which i think is low considering it should be 185bhp. I had a problem which my distrubutor cap and rotar arm so i took the whole thing off and replaced it but when i put it back on it might not be in the right postion so the timing could be out..? i have also had my catalsyt convertor taking out do u think it could be running to rich, because some told me that i will need a apexi afc or something like that and that will sort the problem. is this true or not..?

thanks

the rolling road could easily have been out of order . i wouldnt worry bout it. i ogt mine done back in dec and it only got 159bhp hahaha. after a while we knew it was out of order cos a guy with a teg who knew his was 215 or so only got 196bhp. get it done again that figure is wayyyyyyyyyyyyyyyy off
 
Don't get hung up on figures, too many people seem to do that. Whether its the age old 0-60 crap or top speed crap or bhp crap. Just enjoy your car mate, nothing else should matter. Figures are for pub talk.
 
There are soo many things that will affect what your HP is on the dyno. Most importantly what kind of dyno it its, and how it works and goes about taking measurements. Some dyno's are more accurate than others, while some work completely differentlly. You should call the shop and have them tell you how their dyno works and takes its measurments VS. other dynos. Then get back to us.
A mugen intake isnt going to be any better than any short ram on the dyno because its cold air feature is for daily driving. If the hood was open while making the run a cold air intake doesnt matter so much.
Adding an exhaust thats supposed to make 8 hp over stock plus a de-cat thats supposed to make 5 hp then a CAI thats claims another 10 hp should get you 23 hp right?? Thats a common misconception. Some mods cause you to lose power on an ek9 while others would be lucky to gain you half of what they claim. And then dyno figures can be affected by air temperature, engine temperature, engine conditon, even the condition of the oil.
You also have to keep in mind that most all stock cars will not make their claimed HP to the wheels when put on a dyno. (except for maybe the GTR R34 skyline) I would say your dyno #'s are definitely whithin normal spec.
 
hmmm, check compression... the dc2 r and ek9 shouldn't be any diff, thats for my run anyway...
 
164 bhp = wheel hp ?

bhp(brake horse power) is the actual engine horsepower. As soon as your car stars moving, 10-15% of your bhp is lost due to friction in order to be conveyed to the wheels :(. I'm not sure whats the conversion for turbocharged cars though :nice:

Thanks!

So your HP is correct, 164 bhp is like 180 - 190 HP!
 
during the test did you take your wheels off the car? or did they stay on the car? if you kept the wheels ON the car, then those numbers are whp and they are correct.

No rvm, I think you are a bit confused mate, he said 164 bhp(engine horsepower) which means, the whp(power transmitted to the wheels) is even less(minus 10-15% of bhp). Hp and whp is the same meaning wheel power, but bhp is engine power.
For example B16B: 185 bhp(brake horse power), ~165 whp(wheel horse power) :nice:
So if the dyno read well, he lost 20 bhp from nowhere!! :nerv:
 
Mine was on the rollers a couple of months ago and managed 184hp, 136.7hp at the wheels I think it was.

Just an RS*R exhaust and spoon drop-in.

Sorry ! my mistake!

In what kind of dyno did you test your car? :)

What I say in this thread has nothing to do with my car, also I haven't dynoed my EK9 yet, is for mate goolash786 who started this section, I have my doubts if he got confused and instead of reading bhp he read whp. So I believe the 164 bhp he says may actually be 164 whp which is the correct for the EK9 :nice:

Thats correct, the whp also depends for the dyno, at last there's a dyno in my country! :bow: a friend of mine went to the dyno with a stock ITR and he made 155 whp! I thin it is a little low, but a lot of people are getting like 10 whp less from the El Salvador dyno, maybe its the brand of the dyno :nice:

Whatever it is called the dyno either El Salvador or El Mandador **** it!!! Why to get upset for a dizzy dyno and think that your car is problematic whereas the opposite happens!! You already know how your car performs :woot: I would never paid $200+ to get inaccurate dyno measurement and start making assumptions :blabla:
