well i finally got to dyno the car today after the build, the numbers i think were not bad sure could have been better if i could have turned the boost up, well i dynoed 330.59 rwhp and 271 tq at 17lbs of boost running 110 0ctane., but i ran into a little problem the car started breaking up top at around 6500 rpm so i had to get off (i can rev my car up to 8- 8.2k) i think it was because of the spark plugs, now my question is what kind of spark plugs should i use.... i wanted to dyno the car at 25lbs of boost what kind of sark plugs can handle that kind of boost. i was running ngk iradium 8 that i got from enjuku i gotta take the car to the track on saturday so any input will helphere is a small list of my modscp 86.5 stock compression pistons crower rodsarp main and head bolts and studssp60-1 with a .48 back housinghks 264 cams step 1greedy intake manifold880cc top feed injectorsaem ems with a 3.5bar map sensor
