been on loadsa different rollers before my high comp build and got
anything from 154bhp-169bhp:shocked:
that was on a b16a2

even on same rollers..same mods..diff day....7bhp difference :angry2:

was at "henry roys" place in scotland at w`end to get car set up via crome on
a p28 ecu
all i can say is that this guy is a honda wizard :bow:

totally transformed my car....185.5bhp and 122.8 torque
and this guy just aint just dream up the results!!!

this was on a b16a2 high comp build....oversize b16b pistons...98 spec
teg cams etc etc

all in all if your car feels good then thats good enough :D

What dyno does HR use? just out of interest?

What makes you think a Dyno Dynamics cannot give an accurate result?

Do you even KNOW how different manufactures get factory hp results??

HP results are calculated figures. but do you KNOW how different dyno manufactures even calculate the CALCULATED hp figures??

dc-sports mani - buddyclub cat back - decat - j's racing induction kit and many more - and the list will continue very shortly - and the horsepower will rise. if i went back to the dyno after spending £££££ on my car and i made 170 out of a b16b conversion i would not be happy

You may have spent a lot of money, but nothing special there in parts.

As for manufacturers and their power ratings:
Horsepower - Wikipedia, the free encyclopedia

They also used a rolling road which in all effects has been proven to be not as accurate as an engine dyno or one that is driven off the hubs of the car.

:angry:
 
Did i say there was anything special in the parts i bought? - but in all honesty its the first thing anyone changes when starting to get power from a car! i just said they were not cheap ebay parts.

If you read what i said again - "it is a form of dynamometer and has to be accurate." i.e. engine dyno! then the power to the fly and the wheels are calculated!

I just cant see the point in going to a dyno that is going to give you incorrect results - ok who cares that the point of it is tuning, the dyno is clearly giving incorrect figures!

Ok alot of parts are horsepower rated - imagine your dyno run said your car has 380whp and you bought 400hp rated shafts but in reality your car has over 400whp cos it was run on an inaccurate dyno?

If yous didnt care about increasing the power of your cars (whether its HP or Torque Gains you are after) yous wouldnt even have bothered buying all those parts for your car that yous do! This world is full of hypacrits!

....and bad spellers.

I don't understand the part of where you state the type of dyno has to be accurate...especially when you finish your statement with how it has to be an engine dyno.

So are we supposed to remove the engine from the car now to dyno it accurately? If you read that link I posted on SAE/bhp calculation, you'd discover that manufacturers test on a rolling road where this type of dyno has been proven to be rather inaccurate to begin with based factors such as tire pressure, alignment and even strap tension.

Yeah I'm beating a dead horse here because clearly it's not getting through where the dyno is used as a tuning tool PARTICULARLY WHEN YOU COMPARE DIFFERENT TYPES OF DYNOS ON DIFFERENT DAYS.

Per your rated horsepower readings, it would be prudent to contact the manufacturer of the part to discuss with them just what kind of dyno they used to substantiate their 400whp axles or 500ft/lb clutch...if you're worried about the variances of 20-30whp.
 
Im sorry that hypocrite is probably the only word i cannot spell (had to use google), and the spell checker doesnt recognise it!

You are just contradicting every little thing that i say.

My point is that dyno's should be accurate, a biologist can calculate the level of red blood cells you have in your body accurately but you cant get a dyno to tell you how powerful your car is accurately???

Its not that what you are saying is not getting through - i understand that a dyno is thee best tuning tool, but what 'my point' is that it should be able to read your cars horse power accurately.

And the two dyno results for the ek9 b16b to have 170bhp and the b18c to get 172bhp is pathetic. Most innacurate dyno results i have ever seen. Or there is actually something going on with the cars

Or is my point not getting through to you?

Steve iv'e sent you a pm for a price for a power fc supplyed fitted and tuned ,thanks

oh put your handbags down you 2 lol, bhp goes for nothing anywayz the way i see it is its used to brag to your mates "oh i`ve got 180bhp" so what, you can have 500bhp but if you can`t drive then it don`t matter:D if the car feels good to you and you can drive it well then who gives a toss bout bhp........ although my aim is 200 hahaha jk.
 
i have a power fc , but not tunned , i have it disconnected from the car , there is a online manual or something , because here in my country they are no tunners for this.
Dunno if u guys can help me with a manual because mine doesnt have it.
regards.
 
I understood your point long ago Barryl85.

MY POINT was that all dynos will read differently due to calibration differences and variances in set up and even the car itself.

How do you know the car doesn't have 2 degrees of toe out that can sap up to 10whp on a rolling road that would otherwise not show up on a dynapack? A biologist has an easy job in this sense.

This is just the beginning...pathetic or not, these cars are still showing gains indicative of their overall health to begin with.
 
Barryl85: The only way to get an accurate measurement of engine power is to use an engine dyno, which basically means taking your engine out of your car. When manufacturers quote Fly or Crank power, they generally mean engine power.

The next closest thing is a hub dyno, as this reduces the number of variables involved in determining the results.

Most dyno's, however, are the roller dyno's (e.g Dastek, Dyno Dynamics, Dynojet etc) as they are relatively inexpensive. Tuning companies don't buy these types of dynos to get accurate engine power results (as that is fruitless). They buy these as a tuning tool i.e to compare before and after results.

If setup properly (and a lot are not believe it or not), roller dyno's can be very accurate and do their job as stated above (i.e before & after comparisons, for the same car on the same day). If, however, you are wanting an accurate engine power result, your best bet is to go to a Tuner with a hub dyno (most popular is Dynapack).

If you are really wanting to boast about your bhp gains, then take your car for a run on a Dynapack and if it really does make 172bhp, I will be the first to congratulate you. Otherwise, its just pub talk ;)
 
well said.

the ek9 that this thread is about is mint as well.get up a few pics
 
geez, why does this 1890345781934whp figure seems to be so important some? There was so much good points and info made in previous posts, but no one seems bothered enough to register those facts?

Like Mfactory said, the most accurate form of measurement would have to be off a DYNAPACK dyno, providing you have a baseline to begin with. But, since they are off the hub, your wheel weight and tyre selection will affect on road whp. Lighter wheels, more power whp.

And as said, roller dynos have lots of variations to list and list just goes on. Try doing a run and example you get 160whp. After that, try pulling on the strap another 3 times and see what you get on that run. But if you set it up correctly each time, then its quite accurate for measuring your baseline power. AND THATS WHAT ITS FOR!!!!!

In AUS, majority use Dyno Dynamics.

Anyone want to drag my cars?
123whp ek9
133whp dc2R
143whp dc5R

Obviously referring to me there!

oh my car is more powerful than yours! you think thats what im posting for???

NO - im trying to prove a point that the dyno should be accurate.

Wouldnt you assume that there is something wrong with your car if you dont make stock power and your car isnt stock???
 
A dyno is as accurate as the person who sets up the car and dyno.

A car will age, and as it ages, it will lose power. Aren't you the one saying that's a load of BS though, and then add in your pub talk to back up your claim?
