Madrolla68 Dyno Run

[untubbed_20]

My block was o-ringed, fine to around 140rwkw and 20psi,

and use a graphite head gasket, I asked what dyno it was

because there is no way in the world it would make that on a DD dyno.

It would have to make at least 130-140hp(around90-100rwkw) at the wheels without nitrous.,

and it also does this at only 6000rpm, makes no sense, it would have to rev to 8500-9000rpm just to do this!

considering the people i know with money no object 4K motors,

that only make that at the flywheel (135hp)(around 65rwkw),and will happily spend another couple of

$1000 for another 5hp, 300cc will not do it, and they spin them to 8500rpm.

G200 gemini motor, escort pinto 2L and L20's Nissans struggle to make 100rwkw naturally aspirated with big bucks

and all the shit.

I wish you the best of luck and can't wait to see it sorted with more gas, just doesn't add up?

cheers

They certainly do make Iridiums for 5K's Nickos...I have them in mine

I'm not following what youre trying to imply here,the dyno was a std 4WD dyno setup used to dyno rexs etc.All they do is slide the front half forward and use the back wheel setup.Are you saying that this engine cannot make 205HP because it didn't turn harder than 6000.

 

I'm very confused at why you doubt the outcome of this engine,ive got the o'ring tool and the copper head gasket so i will be back into it soon.Billet conrods are ordered and mark my words there is more too come regardless of whether it adds up or not.

:P ;)

what type of dyno was it on? a Dyno dynamics or a hub style dyno, it

would make perfect sense on a hub dyno. If i work out the math,

the motor would have to make 180-200hp at the flywheel at only 6000rpm,

without the gas on a DD dyno. You need revs to make power in a naturally aspirated motor,and they would be massive revs, 8500rpm-9000rpm.

I doubt it because the K motors are the biggest pile of crap aswell, compared

to even a A series, let alone a big 2.0 crossflow OHC cam style of motor.

And even one of those will only make 130hp-140hp at the flywheel at 6000rpm with big comp(12.1), and a nice head, carby's, but baby cam.

Don't get upset mate, you are doing thing different to everyone else

and should be applauded for that, i can't wait to see how you go when

everything sorted, i just like details and hate it when stuff doesn't make sense.

cheers

Now i see how you have become confused mate,the ENGINE made 204HP like i said in my first post,not 204HP at the wheels.

 

Mate i would be over the moon if it made 204 at the tyres at only 6000,that is why i am saying that there is a lot more too come from this engine.I have another 2000 RPM to play with and with this new camshaft should see some really good N/A numbers.

 

Yes it is a different setup and its all trial and error (not too many i hope) but at the end of the day its all research and hope that someone will benefit from all the time and money i have and will pour into this project.

 

Cheers

Ha,ha, I can stop :)

I reckon the conrods have another 100hp in them yet then! I made that power on 12psi.

Yep the o-ringing at that level "should" hold the head down, i had it lifting at the

300-310hp mark. When i got to 260 it started to get harder to make the power.

 

Change the cam and put the biggest jet in the gas system :) , and the power

will be well up there.

cheers

Yep picking up the cam today and will be into it over the weekend ,new cam specs are 50/86 with .440" lift so we will see how that goes.

 

I'm at 75HP shot now so ill ramp it up to about 110HP and see what happens with the bigger cam and more RPM. ;)

Ok block's all o'ringed cleaning the head up now and putting it on tonight.

 

Cams in ,the BIG mongrel one 50/86.

 

So with any luck ill have it going tomorrow.

 

 

Oh by the way what a prick of a job o'ringing the block in the car.

[madrolla68]

Why such a big cam?

 

You won't come on power till 4500-5000 RPM and make peak power until like... 8500 rpm

 

The overlap would also be a bit wasteful with a boosted engine, you'll be shooting half of your fuel and nitrous straight out the exhaust stroke

 

Nick things you gotta do to make more power mate,i have a few selections of cams now and will try them all.I'm not looking for an engine that is nice to drive or fuel efficient mate i want HP and plenty of it.

 

This cam works from 3300 to 7800 so i am happy with that.

[madrolla68]

Sorry, wasn't criticising you

 

I used to have a 42/88 cam in my old KE70 and it a crazy amount of overlap. Now that I know what I know about boosted engines, just curious as to why you went for the big cam with so much overlap?

 

For a heavily worked K engine, I would have expected that going to something like a 30/70 would be about the biggest you would want to go

 

I tried the 32/72 Camtech 609 and it nosed over at 6000,ive just got the car going and it is a heap stronger up top and revs better,obviously down low is lacking but thats ok.

 

Just remember it is still essentially a N/A engine it still has to draw in as much charge as possible and get rid of it just as quick.

[Taz_Rx]

so do you still wanna sell the 32/72??

 

been waiting for a PM. :D

Yeah man got it out,looks like brand new.

[madrolla68]

Yeah you'll find much bigger revs with bigger duration. I loved that cam, as wasteful as it was fuel wise. Wouldn't go back though. Doesn't rev like a twincam... thats for sure.

 

What head work have you had done again? I had a quick peek back through your posts but couldn't find anything too detailed.

 

 

Essentially the head has the same port size as the old 3K large port heads.All i did was put in on a radial drill lined up the port then drilled it out with the correct drill size,can't remember what the size is maybe 33mm or something then matched up the bowl area of the intake valve,exhaust has been ported to enlarge the bowl area and the runner.

 

It started life as a 5K head but doesn't look like one now.

cool. you happy if i get it in a couple off weeks?

 

just got a couple of cars that are out of rego at the mo.

 

btw, think you need to change your sig now! :D

Yeah thats fine mate when your ready.

 

Change my sig to what???.
