KA-T.org / GroundZeroMotorsports S14 does 633RWHP!

[veilside180sx]

We finally got everything to fall into place with the car over the weekend and got it back on the dyno on saturday and cranked the boost. Ill keep it short and sweet.

34psi did 633HP and 511TQ, this is still a VERY conservative tune, the A/F's are in the 10's and the timing is way way down.



I even made it to the track on sunday and this is what the car did.

RIGHT LANE

That was babying it off the line to try and keep the tranmissions together.

[Craving4Boost]

nice......

lean out those AFR...alky injection and dont retard timing as much...cant wait to see

[240Kid4]

Is there any videos?

[veilside180sx]

No he doesn't have any videos. I'm supposed to take some at the track this weekend if he goes. Won't know till it gets closer to that time.

[turtl631]

Hehe, yea, it woudl be interesting to see what alky injection, cams, and maybe a high redline could do. Not that 633 is too shabby Actually, I'm curious as to what it will do with better timing and A/Fs. Way to go Rick! Now you just need to figure out a different trans setup.

damn 600rwhp and only 11's? DUY was in 9's right with 550rwhp? Right?

[ultimatuc]

^ I may be wrong, but I think he had a best of 10.9x.

[klattr1]

Duy was runnin 10.8's at 132 with 30 psi of boost and 150 shot and a good 60 ft. Rick would net close to the same with 1.5-1.7 60 ft range, all boost and no nitrous. If only John Shepherd had KA bulletproof manual transmission available right now, the 60 ft wouldnt be an issue.

BTW, congrats Rick!

[GEO]

Yeah true.

way to go rick.. if he had one for the KA. that would be so sweet!!!!!!!

[dsylvia]

again congrats!

Make it happen KlattR

Or you can just use the readily available OS Giken gearbox internals.

Oh and this graph reinforces the previous conversation regarding SR torque / HP #'s vs. the KA's parallel numbers.

Notice how the powerband is above the peak VE point of the engine, and how the torque is not on par.

Same story for the SR since it's torque peak is around the same RPM as the KA, it just faces more lag.

Loving the numbers, run that slut out to 8200 RPM, 2-step w/ anti-lag, on some 11.50" tire and ride that chariot like Ben Hur hopt up on PCP.

[klattr1]

about the Z32 transmission, i already looked into it. > turbodave.com

$2000-$2220 installed with transmission, custom driveshaft, custom mounts, adapter plate.

about the hp vs torque figures, only time you see SR's matching hp and tq is when they have close to stock turbos peaking out boost at peak tq and boost dropping off towards redline (will definitely offset it). otherwise, with big turbo setups, its usually far off (makes sense for engine design though). with the KA, usually hp and tq are pretty close depending on size of turbo and turbine AR ratio choice. also, notice Rick has a short runner intake manifold which is guaranteed to pull down the peak tq some for higher rpm HP gains.

[Structure240sx]

great numbers rick

there is no need for alky injection since he is already using straight race gas. the afr's and timing were kept way conservitive since the car made the power wanted/needed

Like I said before, up til the 300 - 320 mark is when SR's start to deviate from the peak numbers being similar. Mainly because the turbos start getting big enough that peak boost is seen later in the RPM and setups start to get more and more top end focused. While it does shift the peak numbers higher up, you run into a wider torque band rather than the big peak numbers.

The majority of the difference lies in spool-up being primarily before the engines peak VE and the engines inate ability to just churn out good low end grunt. Just a benefit of the KA.

Oh and if $2200 is installed with the cost of the TT g'box then that is a pretty good deal!

[klattr1]

agreed.

about the transmission, ya, not too bad of deal. nothing is cheap and easy. there's starting to be more options for KA's. PK C4 auto, OG Giken internals, Turbo Dave Z32 setup, Duy's custom chevy transmission, and hopefully Shep's manual build up in the future.

The OS gearsets have always been around. It's the same gears as the SR gearbox.

I'm not a big fan of auto's but for drag racing, you pretty much have to own up to one to be consistantly reliable in large part.

[LEMHEAD16]

Awesome numbers! power and time. I hope some day I can milk my car off the line and pull mid 11's. Your dyno chart makes me jealous.

[95_240sx]

Yeah, I already run the car out to 8krpm, how else did I do 132MPH?

Also, I run 100% C16 in the car 100% of the time. I can get around 3-5 1.70 60ft's out of each transmission before they crap on me. Auto transmission goes in this winter when we have time to do everything, and XcessiveMotorsports will be making it for this car and to sell as a kit.

Special thanks to Ralph @ GroundZeromotorsports.com and Xcessivemotorsports.com

I will almost always run stock cams in this car. Once we get it back on the dyno for more tuning, it will still make full power until 8krpm, I can guarantee that.

[95_240sx]

Veilside180sx, thanks for posting this, and I WILL see you at the track this weekend.

Rick

[veilside180sx]

I'll have to pick up a tripod too, so we actually get some good footage then as well.=)

[hannibal]

Wow, way to go Rick. Those numbers are freakin awesome!

Thanks for the inspiration...

[95_240sx]

Your welcome. Hopefully I will follow up this weekend with an update on times, and possibly power.

Rick

[Checkered-Member]

34PIS?!?!?! that's the pressure in my rear tires...ROFL...

good going.

[nissanfanatic]

Awesome job Rick.

What exactly fails on your trannies most often? IIRC, its the input shaft that fails most often? And the gear set doesn't include a new input shaft does it?

Either way, I'd stop trying off the line too if I was replacing trannies that often. Safe to say you're in the 10s easy. Kickass!

[veilside180sx]

This last time he snapped the output shaft on the trans. Dont' know about the other ones though.

[95_240sx]

Yes, its always been tail shafts.

Rick

[Nismo_Freak]

Yeah, I already run the car out to 8krpm, how else did I do 132MPH?

Your trap could possibly have more to do with the 600+whp in a sub 3000 lb. car than the 8000 RPM redline lol... thats why I mentioned it.

[veilside180sx]

^I'm sure it doesn't hurt anything, that's for sure.
