This weekend I decided to strap the car down and make a few pulls on the dnyo as I wanted to obtain a base line power number for my car.

The dynometer used is a Dyno Jet. It was a hot day @ 30 degrees Celsius. I use Sunoco pump 94 octane at all times and changed my motor oil as soon as the car reached 1000kms. Motor oil used was Motul.

She’s a freak!



Cheers,

 

Kinda on the high side for a stock k20 but nice.

 

that is 7hp over wat its rated at the flywheel? that dyno is reading a little high

 

ya lets hear what other stock si's put down. I went to two different dyno jets on the same setup and had a 10% variance

 

I'm not doubting that the dyno might be reading high, but even if its 10% higher than others it still a good number.

Cheers,

 

94 octane, must be nice, we have chitty 91 here... Could account for some of the higher dyno #s?

 

you put out 13 more ft/lb of torque than the stock rated at flywheel?? not possible. it cant be stock.

 

thats crazy!

you do hear about freak motors though.

 

from 197 to @ 244 huh?

Wut'd you pay for that sum-b!tch?

 

the numbers are kinda high. where are you located and do u have the factory airbox fully intaked and the exhaust fully bolted up?

 

Yeah, shitty dyno ftl. No way your car makes more power than it's rated for.

 

nice output for a stock si

 

the whole graph seems off. but good for you if you believe it.

You do realize that the motor oil used in a brand new car is a special break-in oil right? Its not supposed to be changed out so soon.

And i hate to break it to you...but your car isn't making that kind of power stock. Its not a freak car. The dyno you used is either screwed up or you're not stock. Most dynos I've seen on here using a dyno jet are reading low to mid 180s stock.

Cheers

 

wow.

 

Totally seems quite odd for a stock engine. Cause this is mine w/mods.

RICO_: hate to call you out. but.........
the oil is honda genuine 5w30 from the factory, there are NO special additives and it is NOT special oil. that is a myth.

 

I posted results to share and appreciate the comments, but I don’t have time to alter the dyno for higher numbers. Also, I use a Dyno Jet and they have no way to alter, or modify the setting for higher numbers. Yes, the car is 100% stock. If you think the oil Honda uses from factory is good oil then good for you. FYI when I changed the oil @ 1100kms it was black as tar....pretty good break in oil eh? I've had numerous new cars and race engines and never had any issues with break in.

Next we will make a cat back exhaust, CAI and test pipe for this car. Check in for the results.

Cheers,

Not true...

There isn't a need for a break in additive oil because Molybdenum (Mo) lube is used during the manufacturing process of the engine. The Mo is mixed in when the initial oil is added and then circulated. The oil will contain between 350-400ppm, so there is an additive. GM and other manufacturers use a similar process.

Thank you sir!

 

look at the dip stick on most new cars. the oil will have a green tint because of the additives

 

Just curious, sorry for OT:

After reading the mototune webpage about breaking in, is it wise to replace the current engine oil after 1K with say, Torco (or whatever equivalent) break-in oil? The aim is to get rid of whatever metal that might be recirculated while breaking in. Thanks

Anyone else catch that the smoothing factor was 0 and not 5?

Adding higher octane fuel won't add more power. Actually, adding a higher octane fuel to a car that doesn't need it can actually reduce power due to the fuels higher flash point. From a performance aspect you want to use the lowest octane fuel you can that won't cause detonation.

the (Mo) is used for assembly and just happens to be in there when the engine is filled with HG 5w30.

i wouldnt consider this an additive for the purpose of breaking in the engine. and again, the oil is not a "special" oil. its regular oil.

i guess im right, and wrong. there is a alien substance in the motor from the factory. but, the oil used from the factory is still HG 5w30

adding a higher octane fuel then recommended will burn out your sensors faster to. im not sure how the numbers are high but whatever. stock for stock its a drivers race no matter if one is a freak motor or not!! take your car somwhere else and have it dynoed and see what numbers it makes.

edit: who else noticd that his cars power feel dramatically @7700 rpm's. i kno that the car stops making power at 7700 but damn he fell like 10whp. my graph didnt look like that.
