back yard productions..... 606 whp @ 8600 rpm, Haltech EMS, stock intake manifold \ q45 tb. I want to say unported head w\ factory valves. I saw the dyno chart myself last import drag event at moroso. I specified the rpm, they are innovating the ka, and power still came on at 4300ish with a conservative 11.80 afr. If i didnt have the ambition \ know how \ avalibility to rebuilt my engine myself they would be the people i would call.
possible w\ custom cams, t-66 on a custom tubilar manifold ( Its just a coinsidence that their manifold design was damn near identical with the one that i built, everything about it) and lots of R&D. There are lots of restrictive factors still with their setup. Next season with a race port with oversized, 3-5 angle, back cut with a different intake manifold + AEM EMS (100 increment tuning segments) I do not have any doubt that 700 whp is unattainable.

*edit*- this is one of their shop cars that im talking about. I dont know if this setup is for sale, if so it would be serious money.
