dynoed my ka-t today>> 390 rwhp, 352 ft.lbs

[klattr1]

i went to the dyno again today and made 390 rwhp and 352 ft.lbs of torque at 24 psi. I thought I would have made more power but I'm happy with it. The air fuel ratios are great and the motor survived. haha.But i still make changes and get better results so we'll see what happens in the future.I dont have my dyno sheets or vids uploaded yet but I will as soon as I can.

Congrats! Sweet numbers! Any 1/4 mile times yet?

I have a question...why is it that most turbo KA's torque numbers are equal or more than hp numbers on lower boost? Many guys running 250hp are running close to 250ft/lbs but guys running 350-400hp are running 300-350ft/lbs...why is that? And how much of a factor are cams and the intake manifold..

Don't mean to hyjack your thread, but its kinda related...

KA-T kicks butt again!!!! great numbers cannot wait to see some VID.

that's the nature of the beast. it's typical of long stroke engines to produce just as much or even more torque than hp.

And how much of a factor are cams and the intake manifold..

the stock cams (more so the s14 than the s13) prevent the KA from producing power through redline. the KA's powerband usually starts to fall off between 6 and 6500 rpms.

[andrave]

god damn... I love ka's... that sonofa***** makes more torque than an NA mustang would at that power level...

[MikeMurphy]

damn! Not too shabby with a T3 turbine and a log manifold.

Any plans on going with a larger turbine and a equal length manifold?

[andrave]

why equal length?doesn't make a difference.

[C-Kwik]

Just looking at your 310 HP dyno chart, I can already see your turbine is choking the motor. 24 psi on a larger turbine should yield you some nice gains. Perhaps even a stage 5 wheel might give you some nice gains without necessitating a new mani, downpipe, and piping. 390 HP is nothing to scoff at though.

As far as equal length, Andrave, it does make a difference. particularly in this case. He is using an FMax mani, which can do the job, but it is a log manifold. An equal length or even a tubular mani can make for some nice gains.

[andrave]

no.I refuse to believe in your "equal length" powers.

[Chingon]

then you refuse to learn..

[C-Kwik]

no.I refuse to believe in your "equal length" powers.

Well, they are not "my" powers. I don't have the power to defy physics.

[SSS]

Awesome work I reckon you'll be able to pick up that extra 10hp easy!

[Jeff240sx]

Nice man. I sure am bieng a wuss about dynoing my car... I need to hit the dyno and catch up.-Jeff

[klattr1]

thanks alot everyone. This was the most fun dyno session I've ever been to since there were an a$$ of people.I'm not gonna change much now. I'll prolly get rid of the stock radiator and get something a little more functional. 100 degree weather in SC sucks.Next up is going to the drag strip in the next 3-4 weeks with slicks and hopefully low 12s. We'll see!

-demetrius [/quote] I think he asked why is that the tq and hp are equal for low boost, but different for high boost.(more hp then tq)

[klattr1]

the reason why i made 390 rwhp and only 352 ft.lbs is because my torque curve flattens from 4500 rpm to 5500 rpm. The reason why it flattens is because my air fuel ratios go from 11.8:1 to 10.5:1 right where my car would normally have peak torque. It will make more sense once I get the dyno sheet uploaded.

[WDRacing]

A true equal length of good design will make more power then a log. But there are VERY FEW true equal length mani's available for the KA. Not to mention the rising amount of guys making over 400 on a log style. With the money I save on a log, I can buy a set of custom ground cams.

I am screwing around with building a cheaper mild steal equal length right now. But thats a back burner project that only gets attention when I'm bored and feel like welding somthing together.

Klattr1, good numbers again, I can't wait to see what happens if you lose that turbo.

Exactly!

Redline

[Jeff240sx]

Its not. It's just his chart, and as he said, the A/F gets really rich and chokes some of the power from the motor, right where the torque would normally peak.PSI240sx made 412/415 or something close, and chris may was right around his horsepower level also. Another dyno tuneing will solve his problem, and he knows this.So yea.. in general, KA-Ts give the same tq as hp, or more.-Jeff

[GlacierFreeze]

His site lists that he has JWT cams. I'm sure that has something to do with more HP than TQ.

jay (aka psi240sx) is running a sr20 motor, not a ka.

Next time.. know what you're talking about before correcting me please.-Jeff

[NX95240]

390 whp is very good in my book . i hope my is as good as that . hope anyway.

[Projex240]

I havent looked at ryans web page in a while, but I know the car well. Someone mentioned the turbine housing he has. Ryan upgraded to a sc61 turbo that makes quite a bit more power--if he were to lean out the rich spot he has he would produce a matching tq number to his HP number. The car is totally sick. What really gets me is that the guy is running a CR that yields number that look like 130 across the board--i think thats lik 7:1 or something like that. I cant imagine that car on 9:1 or even 8.5:1. The car boosts just like his t3/t04e--and it was a stage 5. No more lag or anything--just a much more compressor wheel/turbine wheel combo. I love that car.

p.s.---ryan--im still pissed i had to work---when are you getting the website (octane) updated with the vids?

[klattr1]

no time this week Josh. Next week for sure for videos cuz this is my last week of school.Maybe I'll go back next time with 4 degrees advanced base timing on race gas and see what happens cuz MDM techtom says im getting 14 degrees timing WOT.Maybe like 10-20 more rwhp or so.

[Nathan]

Hey Klattr, did you ever figure out if those low compression numbers were because of the cams? now that I have my 8.5:1 motor together I'm getting 180psi across the board, and its not even broken in yet...

[klattr1]

i dont know why my compression numbers are so low. Im just happy that they are consistent.
