Default For those curious as to what a k24a4 can handle (Work in progress - dyno sheet up)

Well here is what i have done

stock k24a4 (accord)
type s oil pump
arp head studs
rbc mani

thats pretty much it... i have done tons of searching and found a lot of people asking what a k24a4 can handle stock... to many none of these got answered... even myself i was kinda curious..

the k24 in the car (em2) is just to get by for now while the other one on the side is getting built.. its about 20% done...

so went to the dyno last night... spent 4 hours on the dyno.. sorry no graphs cause we werent done with the tuning but have a number printout and it was almost midnite when we got done.. and i had to work the next morning..


keep in mind that we set the redline to 6000 rpm
and the clutch started slipping the last 3 runs of the night...
all runs were a pull in 5th

345.6 hp @ 6143 rpm and speed reading of 111.1mph
350.1 tq @3590 rpm and speed reading of 65.5mph

all at 10.8 lbs of boost on a custom made turbo.


so next week the (partially sponsored) twin disc goes in .. i still need axles ... and back for a retune


PS:.... this was all done on a MUSTANG DYNO.... thinking about going on a dynojey and dynapak just to make my numbers look higher.. hahaha

the WCF wasnt inputted on this one so i dont know what it would be with the correction. This was the final numbers for that nite before the clutch finally started slipping



The second sheet with the curves is NOT the graph of the final run. The graph was taken right before the clutch started slipping. It was the cleanest graph so i had him just print it. I think this graph we were only pushing about 7-8lbs of boost. we did probably about 5 more pulls with the slipping clutch after this graph



Heres the VIDEO LINK

Where it all began







Stage 1








Stage 2










Stage 3 - All Done and painted.. and boosted.. singel cam D17












Later it came to my conclusion that i wanted to lower the car to give the rims and tires a more fitted look... but in doing so would make the car sit to low to the ground.. so instead i upgraded my rims to some 18in rims covered in 205/40/18 toyo proxies









Soon afterward... she went into hibernation




to resurface with a new heart transplant








This is how she sat a 2 year ago...
















Finally... UNDER THE HOOD



And here is a closer look in case the other one is a little too far for ya







At first we were going to use my friends camera but since here camera died i ended up using my cmaera phone on my cell
















Well the next day we got a fresh set of batteries going.. heres some pics







Last but not least.. one of my favorite pics





Then we topped the night off with a view






Not with the bodykit off... just a plain old type-r lip on there









And this is how she sits now sort of.... i have a different lip and rims on there now





this is how it sits now with the new lip and new rims




Thanks for looking and have a nice day...






i'll have pics of the engine bay in about an hour or so of the setup


before


after











Heres the car running with some 24.5in slicks









i was kinda bored so heres some new pics















hers vids to go along with the car as well

me against the ITB powered fit

not bad. i have an 03 accord and on 9psi i hit 291whp/272wtq. mind you this was on a small turbo. im going with a new setup and was hoping to get to around those numbers. RAA rods look very weak so ive been kinda weary of going that high.

also, you might make more power by ditching the RBC manifold. a stock k24a4 dosent rev high enough to make use of it. someone already tried it and actually lost power up untill 6k on a k24a4. id try the RBB (TSX) manifold instead

actually we did that with my friends k24a4 in his rsx... and we actually gained more torque thorughout the mid section... it was in the same day.. we tunedin the morning with the tsx mani... then later in the afternoon after swapping to the rbc gained more without tuning... but thats just one car.. everyone will yield different results

so after you tuned for the RBB and then swapped to the RBC you picked up power across the whole powerband? im still debating on what IM i want go with for my new build. i have an RBB sitting on the shelf

I have to ask... What size turbo?
I'm running 10psi on my k24a4, with an rbb manifold. Sorry, no Dyno yet. I have to upgrade the fuel supply system and downpipe first.

custom trimmed turbo... i guess one could best describe it as a 50trim on the exhaust side with a 60trim on the blower side.. its like taking a 50-1 and mating it with a 60-1

3inch downpipe with 3 inch exhaust all the way through

Nice work!
You made 345 @ 6143 with the redline at 6000??

yes you read this right.. it was set to 6000 but when it was held up there it revved past it a little.. not by much. i assume its the sturbo still wanting to rev the motor more..

dyno sheet up... check first post up top.....the WCF wasnt inputted on the first one so i dont know what it would be with the correction. This was the final numbers for that nite before the clutch finally started slipping


The second sheet with the curves is NOT the graph of the final run. The graph was taken right before the clutch started slipping. It was the cleanest graph so i had him just print it. I think this graph we were only pushing about 8lbs of boost. we did probably about 5 more pulls with the slipping clutch after this graph
