like i said above when we pulled timing back to 10deg and all knock retard went away it makes me think the knock is real.
not really sure about anything and am open to ideas.
i am 99% sure the car is going to get a meth injection set up. should help with lots of things. i didn't want to spend any more money right now but as it sits it just isn't quick enough.

got some newer pics up. http://neufamily.org/images/g8gallery/
also a new dyno numbers and track times after the AIS meth kit.
http://neufamily.org/images/g8filespics/477hp779et.wmv << thats a big file. for those of you that would rather read about the results i will type them up.
best numbers before the meth were 419rwhp/411tq on a mustang dyno. we were fighting knock. injectors were 100% a/f ratio was climbing fast. a safer 5psi gave us 375rwhp but even with it tuned with plenty of fuel and low timing we were still fighting knock at the track.
after the meth we got it turned up to almost 10psi, 16deg of timing, no knock at all, a/f ratio in the lower 11's, injectors at 80%. the meth kit was an AIS system with the trunk mounted tank and progressive controler. 2 14gph nozzles and pump running full blast by 8psi.
new numbers... 477rwhp/504rwtq. this is on a mustang dyno.
at the track i had to work the shift points a ton. shifting at 5600, any sooner and it falls off hard. i suspect valve springs. 1-2 shift is now commander at 5100 to get it to shift at 5600.
best et was 7.79@95 with a lowly 1.99 60'. running at 9psi. there is more in it as it sits.
these numbers are with the stock 5 muffler exhaust, stock dod cam, stock converter, stock injectors.
complete list of mods are. hp tuners with 2 bar os, lc1, twin 60mm turbos, 265/40/18 dr's on stock rims, AIS meth kit.

we are on drag week with the 67 wagon we built and the g8. g8 is doing well.
11.95@122 on sunday 9psi
11.90@122 on monday 9psi
11.87@122 on tuesday 10psi
11.44@124.5 on wedsday 10.5psi
11.87@122 on thursday 9psi
wedsday was at summit track. that place kicks ***. it was also perfect weather and i did the syty shuffle to help with the 60'. still only a 1.92 on that day so there is another easy .2 right there.
still stock cam, converter, 5 muffler exhaust. thinking exhaust, valve springs, a 3rd meth nozzle and then a little more boost will be the next mods.

pull up to the line and stage(both lights). put it in neutral. push the brakes hard. give the engine a good rev. brake pedal will sink farthur and you end up with more brake force than normal.
put it back in gear, then floor it while holding the brakes, wait till there is some boost and then let it go.
