this is my dyno from my h22a engine swap it makes me wonder --- the engine came with a fuel regulaor on it is there such a thing as a 4th gen type s in japan please help explain it ,,,,, I nor the folks that installed can

and YES that is 198.1 whp and 197.5TQ on a N/A h22a engine

specialedition

i meant 167.5 tq sorry

rjr162

the almost 200 hp seems more like the correct amount for reading at the crank.. not sure what to tell you

Kal

very strange.

specialedition

that is whp measured on a dynojet --- 198.1 whp --- they said it could be barometric conditions but it should not matter that much

ALTERED4

did you make the runs with an open header? any other mods?

PreludeRacer023

i got 196 on a dynojet with my stock internal jdm h22..i/h run open/cam gears/and p28..it can be done im sure

specialedition

no the car has an injen intake, dc sports cermaic headers, invidia cat back system which sounds awesome hooked up to the vtec.. vafc, lightweight flywheel, act clutch and this is a n/a jdm motor ---

My friend who imports cars for a living says there is but it was of limited production, 220 at the flywheel and a 11:1CR. i've seen only one ever and that was on the japanese private autcion pages I get sent, never seen one before, never seen one since.

I bet your chuffed with that motor.

The midrange right before VTEC seems pretty strong, seems like the power you make right before VTEC helps your peek numbers. Anyways, does your H22A head have a stamp with either P13 or P5P? Do STD numbers read higher than SAE corrected numbers?

You can say that again!

Yea I'm sure this type of power is possible. My friend dyno'd his bone stock JDM H22 at 181whp 153tq... stock header, custom poorly bent piping exh for 90 prelude, and stock intake pipe with stock filter

Add high performance products and those numbers up there are real ^^

Nice power by the way

Pretty cool to see this motor in that classic 90 Prelude

patastinky

have you opened her up and looked inside!? maybe you have some aftermarket cams in there.. ::Shurgs::

it has a p13 stamp pn it

From our experience with the Dynotjet, any measurement other than SAE corrected will almost always be higher....We would get the Supra "dyno Queen" guys to print sheets with no correction, sometimes adding 15 or more whp. That is why it is good to keep all measurements corrected to the same standard. You could dyno at our facility and go to Houston or Dallas (300-500 miles away) and the numbers would not vary by more than 1 or 2 horsepower....that is as long as the same methods were used.

oh ok tom you are talking with a math genius and I did some fiqures ---
lets first look at torque corrected horsepower which is defined as
hp=Tq*rpm/5252
where tq = torque and rpm = rpm
my std dynojet plot is 167.50 at 5900 rpm give or take 50 rpm so that would correct out to be 186.57 hp to the wheels

next lets look at as you call it cf on a dyno jet which is SAE
the cf = correction factor
cf=1.180[(990/Pd)(Tc+273/298)^.5]-.18
pd= barometric pressure measured from 600-1100mb
tc= tempertature in celius
so it was around 78 degrees F which is 25.55 degrees celius
barometric pressure was around 880 which is an area graph
so that would make the cf(correction factor around 6.5 horsepower)
ok now that would make torque corrected horsepower around 186.57
and the total whp with cf of 6.5 equal to 191 whp

which still kicks in my book

satan_srv

what's the corrected torque figure? the figure posted is ridiculously high...my bullt 12:1 CR motor made 167tq at the wheels...

Daemione

The torque curve before 4,500 rpm's doesn't look like any H22 I've ever seen.

I know I need some help fiquring it out as well they rated std horsepower so I am wondering if there dyno was off or out of adjustment cause I have never seen an h22 dyno over 150 at the wheels before it goes into vtec I took a type s dyno sheet from prelude online dot com and overlayed it it was almost a perfect match looked like the same engine take a look at some pics and tell me what this is I have never seen anything like this before on a jdm or usdm perlude the shop that did the swap said the wiring was different then they have seen on the 40 or 50 swaps they had done on h22s ---

I kinda also thought that it might be a japan circuit race engine (I know they race k series engines and sure they may have raced h series back in the day..) because I tell all you honest I have had eclipse turbos the 210 hp jobs and this thing pulls harder and as strong as the mitsu turbo eclipse I owned
I am not some ricer tring to make a claim on something that did not happen call 501-847-RACE
talk to don he can tell what the numbers where he saved it and can share the info he said he has seen only one other h22a all engine car put those numbers down and it was a Type S ---- anybody offer any info please

Not trying to call you a lier or anything...But it almost looks as if the head has been off the block...look how clean it is...just a thought

OTT

See what compression numbers you come up with. I'm sticking by my type-s guess.
Did the shop say it was from a JDM 4g?

that aint all that clean, Anyway its a swap. They'll have used somthing like brake clean and given ita quick spikNspan. In Business a products' clean apearence is good for keeping post purchase syndrome at bay

EK22snatch

dayum! no matter what this guy has for internals, whether it be oem jdm ****, or aftermarket, i still think he deserves props for some good numbers. how does the head look when the valve cover is off anyways? you should score us a pic or two of that

get the SAE corrected numbers

with numbers like that I aint doing anything with it --- just drivin it I will however but it on the dyno again real soon I need to make sure this was not a fluke ... i may read compression numbers soon though thanks
