Hey guys, Martin from XAT. Here are some numbers on the stage II kit. I am flat out impressed with the power on this and I have dynoed and tuned hundreds of cars and setups. PJ at Boost Designs did a incredible job matching their new spec turbo for their kit to tha KA24. The dyno chart does not lie.. 8 psi by 3300 rpm !!! 240 foot pounds at 3300 rpm... Recirculated wastegate. The clutch slipped once because it is fresh and not broken in yet .. but it was for a 100 rpm section (loop you see) This power was on 12.1 psi on a E-01 and timing was conservative.. I was running about 18 deg timing at peak boost and a pretty fat fuel curve. This is incredible power that stays and makes the car move all the way 6700 rpm. E-Manage does a decent job but we will be doing rom tunes in the future... and PJ will be offering this with his kits pretuned through Scott (Enthalpy).Will have some stage 1 low boost runs tomorow.

Is it really fair to use the admitted clutch-slipping numbers for peak power? Because aside from that loop.. it looks to be 280-ish horsepower, and not quite breaking the 300 barrier.

looks impressive. what is their new turbo? sc50/t3to4e? it should do well with the ROM tune (i dont know the limits of that profec e-01, im guessing its similar to an s-afc?)

keep up the good work, hopefully my dynos will look like that someday....my manifold seems like it flows very close to that (full boost by 3200ish on a .50 trim)

 

couple things....

1) try dyno tuning a car after the clutch is broken in. if it was brand new and youve alrady slipped it, hopefully it will hold after break in, c'mon martin, you know better

2) present your dyno charts using SAE correction, that way people have a better idea of what this thing will make compared to other kits bc everyone else uses correction.

3) most other people also set their smoothing to 3

4) whats with the dip in air fuel? were you not able to set it to 12:1 all the way accross?

Nice turbo. It's apparently got a mercedes/dodge 5-bolt flange on it, so it's unable to mate with any other non-boost designs parts. Much like the rest of their kit parts.

1. slipping clutch on a resurfaced flywheel is COMMON.. the customer needed the car in a very short amount of time.. no time for a 500 mile break in.. will redyno after it breaks in and i will break 300-310 no problem
2. read johns reply
3.smoothing at 1 just goes to show how smooth of a tune this is... hell i'll even set it to 0 and i would love to see anyone get somthing this smooth on a e-manage
4.stock block ka... cylinder pressure ... that is why the dip

 

COMMON?

Maybe you need to take more off of the flywheel surface, as well as get the step correctly on the flywheel, so you get OE specs. There should be no difference between a re surfaced flywheel and a brand new flywheel in terms of how a brand new clutch grabs.

 

thats pretty impressive. how long can a stock ka handle that much power?
