NA KA24DE motors love to breathe!... My stock motor dyno... PICS!... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Nikeboy355 · 02-12-2008, 06:31 PM

pic below

Took my car to the dyno today... Here are the mods...

Rebuilt S14 KA24DE
eBay intake
Greddy 80mm downpipe
Buddyclub Spec 2 80mm exhaust
80mm testpipe

That's it...

155.0 WHP
155.9 WTQ

Here is a graph comparing this KA24DE with my old SOHC KA24E motor...

and here is graph comparing with the silencer in and with it out...

So it looks like KAs like to breathe... No power losses anywhere!... 11 HP gain and no loss in torque... An improvement on both powerbands...

I think this is consistent with all the NA KA graphs that we have seen recently... These motors aren't bad at all!... A usable powerband from 3500-6000 RPM... Playing with gearing could really yield a lot of improvement at the track...

A while ago I remember a guy, Alex Chang, who moderated on another forum and personally tracked an S13 with a stock KA... He did a similar experiment where he wanted to see if the "loss in torque because the exhaust is too big" theory was real... In his case, he noticed the same thing... The KA likes big exhausts and there was no losses anywhere... Here is his graph from a couple years ago...

His mod list was:
S13 KA24DE
AEM cold air intake
JWT ECU
PDM testpipe 2.25"
5Zigen Pro Racer 80mm exhaust

Alex also competed in Formula D as well as plenty of road course events all over California...

And then there is Derek's graph that I like to compare against... Another heavy breathing NA KA... I like looking at the ITBs versus the Omega intake manifold...

The blue graph is with the ITBs and the red graph is with the Omega Motive intake manifold... Big difference just by changing the manifolds!...

Videos coming...

kamikazekid · 02-12-2008, 06:41 PM

thats not bad at all, I wanna see someone fully build an NA KA.
-lightend flywheel
-aluminum driveline
-Intake
-exhaust
-cams
-valves
-ported and polished
I wanna know what those numbers would be. if it was in the 200hp range, i would seriously consider throwing some cash that way.

wannabe_drifter · 02-12-2008, 06:42 PM

On the last graph which curve represent which intake ???
What were the other mods ?

Is it only me who think its werid that the S14 engine is quite a bit more powerful than the S13 even though the S13 has a JWT ECU. And by 15 hp !!

Could that only be the 2.25 inch test pipe ???

Yea pushing 200 with thoes mods if its true id jump on that too : ) siick

anyotherone · 02-12-2008, 06:50 PM

Your motor is very strong to pull 150whp with just exhaust.

Most people really won't listen when it comes to N/a KA... I posted up some before/after dynos a couple of years ago with some mods and here was my results.

Run 2 = bone stock KA24de 88,000 miles
Run 7 = blitz realize 3" catback exhaust
Run 14 = 3" Catback + crappy pacesetter header

Sorry, they exported weird and the torque got cut off.

Oh, I just noticed that your motor was rebuilt, that would explain some extra power.

*s13 drifta* · 02-12-2008, 07:03 PM

Very nice nikeboy, I can wait to dyno my new s14 swap Im doing with a bunch of bolt ons and tuning, I will post up dyno charts when its done.

Daryl · 02-12-2008, 07:30 PM

Great numbers! Not bad for a first time rebuild!

tschad · 02-12-2008, 07:51 PM

would you do cold air or short ram intake on a kade?

HemiCharger · 02-12-2008, 07:53 PM

not bad for a frontier engine. Put a turbo on it and watch it double.

UsJdmTUner · 02-12-2008, 07:56 PM

thats what im talking about.... KA FTW....

Short ram, better throttle response.

Anyone can throw a snail on and get power, NA power FTW!

What I think I get out of all of this is that we can extract more power out of this motor as well as tune how we want the powerband to what we desire...

Do you have any idea how much trial and error testing went into that car?

long stroke motors just simply aren't power happy up top.

soreballz · 02-12-2008, 08:12 PM

Nikeboy, are you running a cat at all? Or a test pipe?

GREAT numbers, btw. You should swap to the 248/248 setup (with the cam gears drilled to be "adjustable", as well) and see how much more power you'll make then.

KA240SX808 · 02-12-2008, 10:41 PM

155/155 w/ I/H/E is pretty impresive

kandyflip445 · 02-12-2008, 11:01 PM

He didn't say he had a header...did he?

Dutchmalmiss · 02-12-2008, 11:08 PM

Jeeeeesus those are insane numbers for such a near stock setup. I'm curious to know if your SOHC motor was setup the same way (i.e. bolt ons w/ rebuild).

markyboi · 02-12-2008, 11:43 PM

i think one of the reason he is getting such high numbers is because he had a rebuilt engine. The other engine dyno did not say if their engines had a rebuild.

those numbers are nice btw. props to you

DreamN · 02-12-2008, 11:50 PM

ditto, it's a fresh engine so it's pulling the numbers it should rather than an engine that's 10+ years old with 100k+ mileage on it.

Can't wait till I have enough to rebuild mine with some goodies and hopefully put down the same kind of numbers.

Anto · 02-13-2008, 01:24 AM

True, rebuilding a motor isn't TOO expensive & can is a good starting point for turbo as well.

yeah i built mine and had just bolt ons including lightweight flywheel and such and put down 150ish with low comp pistons, Derek Greaser is local to me, and his setup has been gawked over for awhile now on forums, but if you wanted similar results expect on spending over 10+ g's on it all together, he works at a shop that has a flowbench and dyno so he did it all as research and development, so he didn't pay for most of it

The Chad · 02-13-2008, 07:20 AM

Check out PDM-Racing's Track car on their site. They do all their own tuning and claim to have "hacked" the KA24DE ECU and have tuned it to close to 180hp with only their cams and the ECU and i believe basic bolt-ons...i.e.: Exhaust, Intake etc... Pretty sick to me

Neejay · 02-13-2008, 07:48 AM

Niiice numbers.

Yeah, on my stock non-rebuilt KA24DE I/H/stock exhaust + stock cat = 134hp/134tq

There's another dyno day coming up on 2/23 that I'll be attending again since I've installed 3" dual N1s + resonated 3" test pipe.

Would an exhaust leak in the piping cause a noticeable loss in hp or tq?

dragon_x330 · 02-13-2008, 07:48 AM

Brian Crower Fully Counterweighted crank that bad boy and throw on some high compression pistons, JWT cams and ITB's not to mention a port and polish and watch that baby revv up high and make some mean HP numbers N/A.

Btw...anybody hear from the BC Crank steup yet? Still have yet to hear what kind of benefits you'll get from that $3000 crank...

HKSdrift3r · 02-13-2008, 08:26 AM

sick numbers man!! KA-(t is the shiznit also) or go home!

LoL... I called Alex on the phone back in 2002-2003 cause I wanted a exhaust and no one really carried 5zigen. I wanted a 3" but he strongly suggested 2.5" for NA. Then he goes back on it years later after I went from 2.5 to 3"

sigh...
