PhatKA-T.com 502 WHP

[IvanAtSPRacing]

I know I promised you all an update on my projects so here it is.

The twins S13 (PK R&D car) finally had enough miles on it to push a bit of boost thu it. We started out at base boost of 10psi and worked out way up. In the low 20psi range we started to have some issues. We ended up having to gap the plugs down from .030 to .025 due to missfiring and the clutch also started slipping at peak TQ (520+ TQ) To over come the slipping clutch we ended up rolling into the throttle at about 4600 rpms (past peak TQ) so that we could get HP numbers. At 25.5 psi we made 502.13 whp and 482.99 TQ. These numbers are UNCORECTED actual HP we made today. We reached our goal and called it a day. I will address the igniton and clutch issues soon so stay tuned.

Wow, that is awesome. congradulations and have a happy new year

[nissanfanatic]

Nice.... Keep it up.

[Structure240sx]

great numbers. good work. cant wait til you get the bugs worked out

[fiznat]

Go, stock rods, go!!

Hey Ivan what kinda duty cycle were you at on those injectors at peak? 95lb sounds pretty damn big, are you having any issues at idle? (what RPM is your idle?)

Ohhhh god man you're giving me chills thinking about what these engines are capable of. Simply amazing Ivan, I cant wait to see more and more- even though this is enough to blow minds as it is.

[MaxType 240]

If the AEM EMS is as capable as the TEC3, then he shouldn't be having any idle issues

Phat - What clutch are you running BTW? What are you upgrading to?

Foster, Thanks.There are no idle issues at all. Idle is about 800 rpms. I never looked at duty cycle because with injectors capable of 800 HP, I knew I wasnt even close to maxing out the PW. I am sure it was somewhere in the 60% range tho. I still have 5 psi left to go before we max out the MAP sensor so hopefully, somewhere in the mid 500s WHP should be possible.

The clutch is an ACT Max series pressure plate and a street disk. I believe its rated at somewhere in the 300s WTQ range. We pased that up with the stock motor a long time ago and it held up till now. I am thinking about just getting a 6 puck disk and running it with the current pressure plate and stock flywheel.

[Joelo S13]

Congratulations on those very impressive numbers. What's your HP and TQ goal on this setup? How much boost can the AEM handle?

[slide240slide]

Awesome, now someone needs to show that punk Rikdaddy in Super Slow magazine what a KA-T motor really can do! that is just stunning, basically stock top-end and over 500HP

[IvanAtSPRacing]

Congratulations on those very impressive numbers. What's your HP and TQ goal on this setup? How much boost can the AEM handle?

I would say that I reached my customers goals about 200 WHP ago. My goal will be mid 500 WHP and mid 500 TQ at 30 psi.

I am using a 3 BAR MAP sensor so for this setup, that would be the maximum boost the AEM will see.

With a 5 BAR MAP sensor we have run up to 52 psi on the MKIV Supra.

sweet ,kept up the good work..

What's the 6 puck rated for off-hand? Also, any plans to drill for a 240mm flywheel clutch combo? I'm afraid my build won't hold so I've been looking into it. That would increase our options...

very very nice, now can't wait to see your car run 10's off nitrous.

[574-240sx]

Very impressive. I would like to know the long term reliabilty on the factory rods shotpeened. It should pretty solid. Good job.

The reliability should be solid, but knowing Ivan and how he is. He will push them until they fold. This is the guy that pushed 3 completely stock blocks until the pistons crapped out just to see how weak they were. Good for us. More work for Ivan.

[Florida240sx]

Was this with your new intake mani?

[IvanAtSPRacing]

Was this with your new intake mani?

The new racing intake manifold was NOT used for the dyno runs. After the clutch and ignition issues are worked out, a set of cams will go in for testing and then the new racing intake manifold will be tested.

[TurboKA37]

wow, i noticed you can see the manifold start to glow at the end of the run

[IvanAtSPRacing]

wow, i noticed you can see the manifold start to glow at the end of the run

Your the second person to notice that. Good job Yeah, it gets hot.. really hot. The PK manifold is sched 10 SS which is about 1/8" thick material. I didnt heat coat this manifold specifically to evaluate the new materials performance.

Congrats on busting 500 Ivan. With a ton of mods left to explore you guys are only at the tip of the spear. Keep up the great work.

WD, thank you. It will be interesting to see how far this motor can be pushed.

BTW, its nice to have you back and in sober form

[WDRacing]

It was an interesting Holiday vacation to say the least. Lots of blurry memory segments.

[slide240slide]

Ivan, how much bigger are those BBC rod bolts than the stockers? and did you knife-edge the crank? I am still stunned that the KA motor held up that well with stock rods that had just been shotpeened and a few other mods.one other question is what type of rings did you use? Peace out!

[95_240sx]

Congrats Ivan. Like I said on ka-t.org, it will be interesting to see how PK and Ka-t.org do this year.

[WDRacing]

Allow me to be the first person to call Ivan and SP out for the next NICO meet....

LoveYa Ivan...
