H22a Dyno results

[Luke Accord]

Hi all,
Just wondering what people have been getting out of their H22a engines?
Recently had mine tuned and wasn't happy with the results?
111kw's atw it's auto by the way.
Thanks.

[MRH-22A]

hey man,
had mine dynoed twice... first time at powertune and got 126fwkw. second time was somewhere near penrith and got 106fwkw.

[gReY-oNe]

^^ wtf 20kw diff??
WHOA!!!

i think mine dynoed at 110kw soemthing like that anyway
at bel garage

[MRH-22A]

this may be a bit off topic... when on the dyno, would the speed limiter still kick in?

[aaronng]

Each dyno reads differently.

Is your ECU a JDM ecu? If it is, then it should cut at 180km/h.

Thats not a bad figure, ditch the auto you will get somewhere in the 120kw area. Not only do those auto boxes slow you down but they are pretty heavy!

what does the weight of the gearbox have to do with this? :confused:

Yeh the ECU is JDM. But the dyno graph from HiComp shows it went up to 190+... wierd huh?

[aaronng]

So did it cut out or not? If it didn't then your ECU might have the speed limiter already defeated.

[MRH-22A]

I dunno if it cut out or not when it was being dynoed... but what i do know is i have the speed limiter. I cant get past 180km/hr.

Could the dyno be dodgy? 106fwkw and a graph that shows 196km/hr.

[aaronng]

Maybe the rolling diameter of your tyres is larger than stock, giving it a higher top speed eventhough the VSS sees only 180km/h.

I can guarantee you the dyno isn't dodgy. And the power figures are correct. :)

BTW, the EG made just over 130kw the same day.

I had my stockies on back then.

Look man. I've got a dyno sheet from HiComp saying my car was doin over 190km/hr. I paid for the dyno run so give an explanation.

[aaronng]

What was the tyre size on your stockies?

[grumpy rooster]

They have never had any problems with any other cars and there are cars on there all the time. The dyno shows true power figures, not some of the happy figures that show up on other dynos. Apart from that the ET's and MPH that the drag car runs proves the dyno figures.

And just to prove it another way 2 VL Commodores with exactly the same setup made the same power and run the same times, 1 from Hi-Comp, the other from another workshop. 2 different dynos out exactly the same amount, I don't think so.

I'm not saying your making it up, I'm just saying the dyno isn't out.

[MRH-22A]

cant remember... but i think it was 195/55/15

Ok. If the dyno isnt stuffed then why does the dyno graph show that my car went past 190km/hr when it shouldve cut out at 180km/hr?

[grumpy rooster]

I have no idea.

[Luke Accord]

Grumpy Rooster what mods have you done to get 130kw?

[grumpy rooster]

It has a standard H22A with a ported and shaved head (comp around 10.5:1). Everything else is standard including the headers and inlet manifold. The only other mods are a cold are feed with bellmouth from the front of the car and a 2.5" exhaust with no cat and 1 muffler. It is run by an EMS computer and datalogger.

Other little things are machining down the balance shafts, and locking them up, no ancillary drives like air, steer, alternator.

In the near future it will be getting some 50mm TWM throttle bodies and new headers.

[94vtirozguy]

a typical stock manual H22 is about 105kw give or take a few. Auto version usually have a bit less power.

These are stock figures variance +/-5kw. This is with everything stock

[h22a accord]

I dynoed mine, JDM prelude ecu, stock engine with CAI , 2.25" catback and got 113kw atw.


mr h22a, you have an accord jdm ecu yeah? as you got an accord front cut is this right? JDM accord engine & ecu combo is 190hp vs prelude 200hp version.

I have seen my speedo go to 190 kph before cut out too.

No. I never bought a half cut. It's a JDM Prelude Engine and a JDM Prelude P13 ECU (200hp). I've never been able to go faster than 180km/hr.

[lilhaulerz]

my 5th gen h22z pulls 108.5kw.. auto with just CAI

[h22a accord]

ahh ok. sorry mr h22a. what gear box u got? m2b4?


i once had my car on a hoist and the speed limiter didnt cut in.

[sugz]

hes got accord gearbox

[MRH-22A]

Yeah its just the stock vti accord box.

I just checked the dyno sheet again... looks like it cut out at 194km/h. It just doesnt seem right. Might just have to dyno it again one day.

[Brash22]

My stock H22 (auto) was run up on a Dyno Dynamics (Shootout Mode) and ran 102kW.

[BaNaNaMaN]

First run was with stock d16a exhaust
Mates H22 EG made 124.7fwkw

Stock engine with 2.5" exhaust and short ram intake setup.

He is a happy man.

Head work, cams, hondata, I/H/E mods

[grumpy rooster]

So on a Dyno Dynamics dyno it would be about 170kw. Thats not bad.

Surely the bottom end is not standard? And what compression ratio? It must be fairly high....

:thumbsup:

[z3lda]

any pictures of the h2b h22a?

sounds interesting

IF its stock bottom end, thats a pretty good figure.

Can you shed more info on setup i.e cams, headers, intake and etc.

200kw is pretty darn good :thumbsup:

Thats hectic.
Hows the fuel consumption?

Bottem end is completely stock. He lost the cam belt on friday going to the track :(

Will update when I know more about that. The head has crower stage 2 cams, ported intake manifold with secondaries removed. Fully port / polish. Uprated valve springs and retainers (don't know make etc) and a hondata tuning it all.

H2B FTW!

[koj]

wowzer, how much would this all cost? :O

[z3lda]

new zealand car right

thats 200 on a hub dyno though

[BaNaNaMaN]

Yup, NZ car. I am part of the NZHondas club over here.

[sr3]

Very good !! well done !
but I would look into changing your intake piping

[grumpy rooster]

I've been trying to reconcile the power figure and the mods and I just can't see how it can make that much power with such simple mods. By those figures it is making more power than the Alcorns K20 with similar mods. As much as I love the H22 I can't see that being correct.

The only way I can see it making the power is with some huge cams and big compression. Modproject's H22 in their EG isn't even making that power with a fully built engine and decent JUN cams.

Is there any chance that it was 200hp at the wheels? That would make sense.

I am happy to be proven wrong. In fact I hope you can prove me wrong. :D

[BaNaNaMaN]

I have talked to kane a little more about the setup and it is stage 3 crower cams not stage 2 as I listed earlier. The head has had some work done on it to fit everything in and would more than likely (not saying I know for sure or anything) have been planed before fitting
And it has an Import Builder intake manifold, SMSP headers. And a good S300 hondata tune.

Have to remember that it is mated to a B series gear box which will make a difference getting the power onto the dyno compared to a K.

I am trying to get a complete list of mods from kane but have not been too successful as yet.

Here is a little more about the car if you want to take a look. (btw it munched the valves last friday going to the track when the auto tensioner failed and the cam belt came loose, RIP H22. New engine build has already started)

Be interesting to see what times this car does on the 1/4 mile...

[grumpy rooster]

Correction. it would have been good to see what times the car did down the qurater. That would have told the power story. But we will never know now. :(

[BaNaNaMaN]

There is already another engine in the build for the car with the same top end specs and a forged bottom end.

So I will let you guys know the outcome :)

[94vtirozguy]

the power figures are way off.

some guys with built bottom ends don't get 200kw (260 hp).

There is a car with more power, but that car had a heavily modified bottom end and the angles of the sleeves were changed to get this power.

Well we will just have to see how the next engine build goes. But I assure you the dyno is not some back yard special and the plot speaks for itself.

[ATSE]

Opps... correction noted... would.

As you stated the times would of proved the power statement of that motor. Even Bao's car with worked internals didn't make that power...

But netherless interesting to see what power the new engine makes. Record a video maybe....

[grumpy rooster]

A logical explanation is that the power was really hp at the wheels which would calculate to be ~150kw at the wheels. That is the sort of figure that makes more sense.

Then the fresh rebuild with decent bottom end I'd expect in the region of ~165kw+ dependant upon bore, compression etc.

[aus91integra]

does 1300 nm seem right?

[grumpy rooster]

That does seem very high too.

[94vtirozguy]

also another thing would be to see what SAE correction they used.. which is not stated on the dyno sheet

[EUR003act]

does 1300 nm seem right?

i think it'd be impossible for a 4cylinder to get 1300nm of torgue! not even 6litre v8s crack 1000 and they have a shit load more grunt

[grumpy rooster]

Its not torque, its tractive effort which is a multiplication of the torque through the gearbox, final drive etc.

Tractive effort will be higher than the engines torque.
