friends gsr, 135k miles bone stock motor. peakboost with 57 trim and kteller 3". runs were done on 8 creeping to 9 psi. total timing was right around 20 degrees, tuning done on uberdata. i could have moved vtec down a bit, but i did the tuning for free and it was more to make sure its safe with timing and afr than make power.



84mm lsvtec, gsr cams blox im. t3 60-1 with mini ram and 3" exhaust. boost level was 13-13.5 psi and i tuned using uberdata. i wasnt really happy with this power for the boost level, so i went to evans later that week. motor made 340 on 13 psi and 415 on 17 psi from his tunes.



81mm lsvtec, again gsr cams and blox im. this setup had a haggard ccfab unequal lenght ramhorn and dmh 3" ecutout. boost level was 15psi using a t3 60-1. turns out the #2 cyl had 80% leakdown out of 2 bent exhaust valves, and the compression in that cyl was 120 and 180 in all other cyls. this motor ran a whole year like that, over 20 passes at the track and 10k miles daily driving at least.



215k mile stock ls motor with 180 even compression. 57 trim .63 exhaust, log manifold. yes, the afr really is that lean. my innovate or i should say my bosch wideband sensor went bad and kept telling me i was in the 10's lol. lesson to the wise, keep a good wideband sensor handy. either way, this motor ran a good 15k miles, about a year and a half even after running lean like that. it also survived a broken thermostat and an overheating hour and a half ride home from marcus dairy a few years ago. compression was down to around 165 when i took it out, but it still ran fine. boost level in the graph was i think 10-11psi using a stock map sensor

moved the vtec down to 4500 for the first graph. car picks up much better now

made 350 on 12.4 psi and 425 on 18 psi. afr on the 18 psi run is in the mid 10's. the dyno wideband crapped out and i was onlygoing by my plx in the car and didnt want to get to aggressive. im sure with afr in the mid 11s and maybe another degree it would have made about 440.


i was having some good creep issues with this. started around 16.5 psi and i was up to just about 18.0 psi at 8500. i tried switching from tial 38 to tial 44 and it didnt help out much
