Highest whp

[hayato kazami]

Hey guys!

What is the highest hp you think can KA24DE produce? The highest SR22DET i ever see is about 750hp - 795hp running T88

I think KA can produce more than that! maybe up to 850hp

[GELLIS2586]

Who knows no one has done it yet. The most ive seen is 565 with a t66. It could always be more

[Charlie240sxt]

I think that if someone really wanted to push the Ka thay could pull 850whp maybe more but it would be running really hard and probly wouldnt last vary long

[klattr1]

duy produced alot. I believe over 500 with nitrous.chris may made 439 at the wheels at 22 psi.Jay (psi240sx) produced over 400 at 29 psi or so.Mike Lee is pushing over 500 at the wheels without nitrous.Watch out for Pornflakes. I bet he'll be the next highest. He made 411 at the wheels at 17.5 psi. Imagine this car over 22 lbs of boost.Rick(95_240sx) will be making some monster power with his new setup.Supposedly some guy with a turbo ka in a datsun 510 made some ridiculous amount like over 600.

Real Nissan guys with their 10 second KA24E powered cars. Thats single cam in the 10s.

[hayato kazami]

I really think that we should make up a ranking chat for the highest HP KA!

sounds like the KA still have a lot to come!

I am wondering how many PSI it will be IF i want to make my KA up to 800hp...... ^-^

I can't image how is it feel like to drive a 800hp KA

[dareo]

Someone with lots of money, go build a serious KA24 and feed it Toluene and maybe some alchohol on a standalone and see what kind of max WHP it'll churn out, minutes before blowing up. Don't forget nitrous and a turbo that wont spool till at least 5k.

With all the work done i bet you could push 1000hp before blowing it, but who cares? Dyno whores shouldnt be meddling with a 240sx imo. Spend that time learning how to drift a 240sx and if you want rediculous power go build a turbo Hayabusa or a turbo Corvette.

there is alot of guys out there that are not on the forums(FA or NICO). They keep to themselves and dont feed off of internet global attention. I know I can name two of them but they stay hidden because they dont need to be recognized by forum members.One of the guys is in Chicago and the other is in San Diego.I think the point of horsepower kings is valid. Some Supra guys like saying they have 800 rwhp and that's all they want. But when they go to the track, they'll run a 12 sec quarter mile at like 130 sumptin mph. My personal glory would be for having the highest horsepower figure but having a solid track time with that.I respect people that can run 11 sec quarter miles with not a hell alot of power. They know how to prep their cars for the track, how to properly launch, and know exactly what suspension setup will be relative to that 11 sec timeslip.I know its all what intent the owner has with their car(show car, dyno king, all drag, street car) but I dont like what braggin rights those Supra dyno kings have when they cant back it up with a decent time slip.

[dareo]

To each his own i suppose. Power kings are just better suited on a motorcycle or a boosted V8. There is no replacement for displacement. Why fiddle with a 2.4l when you can get something with over 500 cubic inches and boost that for your bragging numbers.

[Projex240]

Its all in the challenge that dyno kings feed off of. Its not the numbers themsleves...its" I made 565 on a 2.4l solid bucket valve train without hydrolic lifters" or " I made 950 with a stock bottom end" Its all about the game---kinda like classes in a show event for drag event. Its about what you made power with as much as the power made itself. I dont think 900 hp on a boosted 500ci block is as impressive as 550 on a 2.0 sr20det, or 560 is on a 2.4L ka. Busa? highest ive ever seen on a street bike is 360, and thats turbocharged on a 460 lb bike-----faaaaaaast.

[illspace]

ive seen damn near 500whp busa...

[Bill]

With enough money you can do anything.

The biggest limiting factor with the KA is rpm's, not many people have fully built the head due to the lack of aftermarket products. I think it is wise to keep it under 7k. If the KA rev'd to 9k then 800hp would not be that far fetched.

[WDRacing]

I'd say 1200 is probably close to max. I figure 800 can be done pretty easy. Over that and things get really hairy.

[d240t2]

Any reason for those numbers, WD?

Last I checked, I have the highest stock bottom end hp at 350rwhp.

Dennis

[GELLIS2586]

hey d240t2 sorry man but i have seen 390 on a stock bottome end. But 350 is a very respectable number. I wish i had that much. Someday i will

[d240t2]

Who has 390whp on a stock bottom end? Maybe I should rephrase...I have the highest substantiated hp claim (as in other members of the online community were there for the dyno session, and many people on the forums have ridden in, driven, and seen my car). Also...my car has been running for 30K miles and 2 years of turbocharged abuse.

[SingleCamSam]

I bet you could turn up the boost even more if you wanted to. If an SR can make 500whp on the stock block i'll wager the KA can too. Both motors seem like they'd take power just as well. The only difference i'd say is the SR with it's thicker ring lands and lower compression can better withstand detonation.

[nolaws4evr]

hey d240t2, i havent gotten a chance to drive your car yet?? when do I get my turn man? nah, just messin with ya man, but seriously tho if youl let me id gladly do it.

I decided I had to post on this one about highest WHP... maybe some of you guys know I work at a motorcycle dealership as a test rider, well, the other day this guy thats been talking bout his crazy setup on his busa, but everone says hes full of s***. well, saturday he comes ridin up, and some guys round me are like, that bike doesnt sound right??? i knew it was him and im like, dont worry about it, its turbo. well, hes got a gt40 w/.47 trim compressor matched to a tial 50mm. he only built it for two reasons, 1 to drive it around everyday if he so chooses, 2 to win the dyno match in daytona beach for bike week. he dynoed it last week in atl at 386hp to the wheel at 9 lbs of boost. oh yeah, it was also fully ported everywhere and polished of course, and bored to 1400cc, new pistons, basically worked over. he plans to run about 36 lbs on the dyno for somwhere over 700whp. the sound this thing creates is absolutely phenominal, has a 1ft long 3in pipe running straight off the turbo exiting through the fairing. I will post up some pics as soon as I get them taken.

[andrave]

does it ever spool?

[kettnerc]

I'm working on building up a FWD KA24 over the winter with a TEC3 standalone. The shop doing the work ran some numbers and they gave me an estimate of around 500hp on pump gas and almost 900hp on race gas if I so chose to do. They're building 9.0:1 replacing everything and doing a full ferrea valvetrain and pushing the rev limit to 8-8.5k.

I'm not saying that they'll hit those numbers, I'm just saying that I'll let you know what happens.

[WDRacing]

Any reason for those numbers, WD?

Last I checked, I have the highest stock bottom end hp at 350rwhp.

Dennis

I was trying to take into account that I don't know how far we'll be able to rev the KA until I get the rotating assembly takin care as well as the valvetrain completely redone. The intake will have to go of course and the head will have to be completely ported. The turbo will have to be extremely large. There wouldn't be much KA left except for the block. I simply guessed at 1200 using similar sized motors.

Thats why I said 800 could be done pretty easy, note I said easy and not the word cheap. It'll be interesting to see how far I can get one to go. Or anyone for that matter. I think the intake is a big weak point. I'm going to use one simlar to the 2.4 Mopar that Sean Carlson races. Or as close as I can come to one doing it myself...heh.

Another thing will be to see who can crank out the most with a stock bottom end. Thats actually more fun then huge boost on forged goodies. Since you can just swap out the busted block for a couple hundred bucks. When are you gonna push yours up??

WD

[d240t2]

I'm not sure if I am going to push mine at all anymore. I'm kind of ready for a new project...and very much out of cash.

Those numbers were pulled on pump gas with plug and play JWT ECU. I'll need bigger injectors to do anything (72 or 75lb/hr). I'm pretty sure that with some slight tuning (AFC), this .82A/R housing I have sitting on my desk, and race gas, I can make 400rwhp easy. I think I can make 400 on pump gas with that housing and some tuning. If I had some cash for a nice equal length tubular manifold, tuning, the .82 housing, and race gas...well...

Really...I have the motivation, just not the cash...and if I had the cash and time, I'd really like to do some body work before I try and really go after crazy hp numbers.

I don't know why there aren't more 300+rwhp KA's out there since I made 350rwhp 2 years ago...I mean, I don't have anything special. That dyno was on a RevHard manifold, plug and play JWT ECU w/50lb injectors, GT Spec exhaust, cams, MSD ignition box, and 2 S13 exhaust cams. I really didn't do anything special or custom to make that hp.

Dennis

[nolaws4evr]

what would be the best size exhaust to run with a setup like yours WD or d24?? and d24, how much money do you think you dropped into your project when you hit those number??

Josh

[WDRacing]

The best AR for what?? To make the most hp out of a Stock KA, or to make the most HP possible with a built KA??

WD

[klattr1]

The best AR for what?? To make the most hp out of a Stock KA, or to make the most HP possible with a built KA??

WD

he might be talking about catback exhaust size versus exhaust turbine ar's.

[nolaws4evr]

yeah, sorry for the confusion. i meant piping size, I was thinking maybe 3in would be perfect for anywhere from 300-400hp, depending on how high I crank the boost. anyways, what are you guys all running?

[WDRacing]

3'' will work great.
