sr20det passed up kat

[2fast2forty]

I have a freind with a built sr. The other day he told me of a guy that came out with an sr that put somewhere around 360, not sure of exact hp. Anyone else fhear about this...?

[Craving4Boost]

i thought u said it was a KA-T who got passed up? what's it have to do with your friend or the "some guy"

and oh well....a geo metro can pass up an KA-T with enough money

creative name by the way lol

[2fast2forty]

Well i have heard that kat and the sr20det have been goin at to see which is better. I just heard it from a freind that the sr20 made more hp now.

Sorry for the messed up title i typed it backwards.

[2fast2forty]

SORRY I TOTALLY MESSED UP ON THIS POST.

Heres the real story. some kat put 638whp like 4 or 5 more than the sr.I heard that another guy came out with an sr that put 660 to the ground.

Sorry for the mess up.

[Import_Ant]

are you asking about which motor currently has the highest peak Hp?

638 rwhp/599 ft.lbs is the current record dyno for a Ka24DE-T as far as I am aware.

I'm not so sure about the record holding SR but I'm guessing the peak is higher. Peak hp numbers are worthless though without a useable powerband imho.

[2fast2forty]

I was just wondering if anyone else heard of it. I thought it was a little weird too.

360 thats it?

I personally saw the dyno on Ivan's KA-t has made 638.

[S13CoupeLuvr]

sr's have been built to 750rwhp

[IvanAtSPRacing]

I am not done making power yet.

Hell...... I am just scratching the surface right now.

638 is with an unported head, stock size valves, stock intake manifold, stock throttle body, tiny intercooler pipes, an intercooler rated to 400 HP, a restrictive T3 back half, no NOS, stock red line.....

I dont know what the record for stock displacement SR is but I am sure its more then I have made so far with the KA. I am also sure that whatever it might be, I will surpass that number in the near future.

[Craving4Boost]

ivan your scaring me

[SlidnSideways]

Ivan i just wanna say that your my hero...lol...go get it! Im working on a ka-t project and im worried that im gonna be left in the dust terribly against my brothers built sr.

[PapaSmurf2k3]

ivan for president?

[hysteria]

i think (for the US anyway) the highest horsepower stock displacement sr was done by a place in cali called phase 2 motor trend... they got ~700+ to the ground and then engine lasted for 1 dyno pull and died. They had EVERYTHING done to that engine, so i'm definitely thinking that ivan can beat that number because of what his engine did with such a *crappy* setup (intercooler too small, stock intake manifold, etc as he has said before).... haha i can't believe i called his setup crappy.

the sr has made higher numbers so far because it has had more support over the years. remember that people started turboing their ka's just recently (the earliest one i ever heard of was 1996 (i'm sure there was one or two before this but that doesn't make a difference for arguments sake), and it was a real big deal because it was all custom fabrication... and even after that it didn't become more popular until about 4 years ago, or something like that). the sr has had people modifying it in japan and other parts of the world that got the silvia/200sx/s13-s14-s15 with the sr in it... so i guess we can safely say that the sr has had support for a solid 12 years now, and maybe more... considering what ivan has done in this short amount of time i think it's also safe to say that he's just scratching the surface.

OK heres the deal, You can have 900 HP but if you can't put it to the ground or the power band is all ghay your not gonna win races. Torque is also a Factor, The way I think of it is Torque is Instant, that split second you slam down your foot torque is there to spin your tires (not always like a burn out but "rotate" would be a better word I guess), HP is a measure of Power OVER TIME- The amount of force it takes to move 550LBS(or whatever) one foot in one second. And the KA has Higher Torque #'s with ~equal HP most of the time, There might be a few SRs that are stroked or something so I won't say allways, So anyways what I'm saying is that a dyno queen that puts down goobs of HP won't allways be the faster of 2 cars, there are several other factors like gearing, torque as mentioned above, Tire size plays a part, plus a engine that pulls 750hp then blows up right away is useles except for R&D to see what went wrong <---- Not for me thats for the guys with the big bucks like Fiz. hehe anyways the KA rules and the SR ain't a bad engine I had one in my sentra (deforced induction tho) and its a great engine and the #'z it can put down are great but don't think that a built SR in the same car would take a KA of a smaller amount of HP, I guess what I'm trying to say is PEAK HP numbers shouldn't get you all jumpy. Sorry for the rant but today 2 dumba$$es asked why I didn't go with the SR sawp cuz its so much cheaper and way more JDM and such a faster motor, the only thing they were right about was that it woulda been more JDM I guess no one thinks that that extra .4L gives the KA an advantage ? oh yeah If I'm wrong on anything feel free to flame me

Travis Burrelle put together an SR his self and made 661whp and 583 ft-lbs on an unported head, stock size valves, stock bore, stock throttle body, small intercooler, and no nitrious. Here's the dyno sheet and picture of the car. Dyno Sheet Picture of SetupWhat it all boils down to is money and your setup. Either 2 of the motors can have bigger #'s...it just depends on the person's budget. As mentioned before, hp isn't everything....but torque isn't everything either. There's plenty of under powered cars whooping up on higher hp cars because of their setup. A better suspension/tires/drivetrain, etc will dominate over a lesser setup. Putting the #'s to the ground is where it all comes into play. Both motors are good, I'm sick of hearing people argue till they're blue in the face over which motor is better....can't we all just be happy that we're into the same interests?!?! (Imports, rwd, 240s, etc.) Too much hate b/t fellow Nissan owners over 2 motors....we should be using this negative energy against other cars....like domestics.

No more SR vs KA threads on my watch...You can't compare the two motors, cause they are different, plain and simple.

Thx

dude, if you are gonna come on the KA-T forum, at least get the facts right.

that 661 rwhp dyno was done with a shot of nitrous (150 i believe). hence the 370 ft.lb increase of torque within 800 rpms.

he tried to push the limits, hence his motor and transmission being toast after that dyno run. at least he was honest about it and didnt keep crap quiet unlike many people's pride that does so.

if you think there's too much SR vs KA-T BS mambo jambo, then why did you make your post? the bottom of the paragraph stuff is all mushy crap which you are using to cover up your Anti-KA-T hate.

LOL

NON AUTO, STREET TIRE 9 Second SR Powered UNIBODY cars.

JUN has been running a 2.2L SR with 800 or so HP into the 8's as well.

The KA has a long way to go to surpass the SR but it has the ability given enough time.

[WDRacing]

NO MORE quotes from Japan....The enginbe has been in ptroduction for over 15 years...of course they have built some badass motors. If it's not residing in a stateside model, leave it out.

Christ, comparing the Sr to the KA is like comparing the SR to the RB, just cause we swap that into a 240 also.

GAY AT BEST.
