freshly built motor break-in dyno results
these were off the wastegate spring only(14 psi)
boost controller was buggin out so we disconnected
it so that we could tune better.
boost cut was set to 18psi on ems off map sensor.

nice power.. i'm curious why you wanna take the car to such high RPM.. are you gonna do that when you drive it?

Too much to list.

too much air to fuel (aka too lean), engine will detonate and you will not be happy.Spud5251 wrote:why, whats wrong. im just curious cuz i dont know to much about tuning.Miami240 wrote:For your sake, i hope the wideband reading was inaccurate.
ur makin 423 off 18 psi though?? very nice!!
KA-T in the works...........
I don't see a person pulling up past 8K RPM in actual driving... Nevertheless, he has 400+hp by 6500 RPM, which is pretty nice. Nevertheless, if he is confident in his motor to handle 8k pulls and driving, then that is a great great motor.
As for the AFRs, you want to be around 12:0 or less in boost unless you've got realllly nice fuel.
I hope your motor isn't hurt.
My built motor took about 5 hours worth of lean AFRS at 12psi (in one cylinder due to a bad injector) before the piston melted down to the rings on one side and completely collapsed my sparkplug and turned my head into a soft dimply aluminum bowl of oatmeal.

im guessing it was off cause we were getting 11.2 readings right at the uegoMiami240 wrote:For your sake, i hope the wideband reading was inaccurate.
guage in car that is hooked directly to the ems and thats my only o2 hooked up.
the guy that was doing the tuning is a certified aem ems tech.
as well as a friend and he told me that he was tuning conservatively cause these were the initial motor break-in runs. we did 14 pulls back to back with no probs.
i dont plan on running that high on the rpm's thats just what he took it to.
I would remind him that the KA is not a honda motor. It has a lot more stroke, which means you don't wanna hit 8K rpm unless you've got some serious work like upgraded valvesprings, retainers, and a fully counterweighted crank.
I wouldn't.. but thats me... different strokes for different folks.

dual springs and retainers
si oversized swirlpolished valves
full head port and polish
5-angle
lightened,polished,balanced,knife-edged, align bored crank

i found out today that the sniffer used on my car was messed up.
we found that out right before my buddy put his drag honda on
the dyno for some tuning runs. here is one of the first ones
668 whp on low boost(24psi) out of 45psi for track
this car will be over 1000hp on full boost.
here is a video of the run

Excessive plus this...HORSEPOWER CHEF wrote:what intake manifold are you using? its just kind of odd that your car is carrying tq alot better than alot of other peoples
It's really not that hard to achieve that curve. I just about had the same curve with just my custom intake manifold.cdigity wrote: the whole valve train is done

im also running a q-45 throttle body as well.
not sure if that has anything to do with the torque
but i figured id add that to the list of things done.
in the next week or two, i'll have the avid racing
motor and tranny mounts in, as well as the driveshaft
shop 1 piece driveshaft, and fuel surge tank built with
aeromotive a1000 added in along with walbro in-tank
so we can up the boost to 25-30 psi and see were we
end up for power.
i'll keep you guys posted.
yes, those dyno pulls were on the walbro 255 only.
kinda pushin it

sorry for the lack of updates, been helping pjHORSEPOWER CHEF wrote:updates?
(aceinhole) with his widebody build.
but yes, there are updates!
yesterday i got the tranny swapped out for another one(old one finally
gave out)
put in avid racing motor and trans mounts, as well as the one-piece
driveshaft.
those mounts are hardcore! everything shakes and vibrates.
loud as hell in the car(gotta sound deaden now!)
im gonna most likely switch to a 300zx tranny since my buddy got
me one for free. just need the conversion kit from rich at xcessive.
still gotta install aeromotive a-1000 and bigger lines so i can up the
boost, and go back to the dyno. just been real busy.
i'll keep everyone up to date.
