Thats kinda strange that you made peak power at 6700 on the stage 4's. When we tested them peak power was around 8800rpm. How did u get it so low?ummm hey guys this is the first time i posted in here and its seem i have the best time :tongue: i got a sr23.5ve , franklin stg 4 cams, ebay cam gears,gen6 3" header, custom air intake, N1 ported intake,80mm throttle, jwt springs, fidanza flywheel, ACT HD clutch, 550cc inj, 3. 25" exhaust with Apexi N1, sr16 tranny, 11.5cr, Electromotive EMS ,and FRAM oil filter... LOL i dynoed my B13 (weights 1,749 lbs) and i got 267.2 whp @ 6,700 rpm ... the AFR it was 12.7 at highest, so maybe we could get 15 more hp... i did a run of 12.03 @ 115.34 mph all motor, that was the best after 3 high 12's trieds... then i ran 10.31 @ 129.62 mph with a 100 shot of nitrous (4 foggers) and since i didnt have roll cage they didnt allow me to race no more... not even N/A... but im refreshing the engine rite now and after that i will do the roll cage ... i want sooooooo bad to get a 9' sec run ... hopefully with a 150 shot i will... then i will take a digitalo camera with me since my friend didnt bring his camera charge and only took a cell camera vid that looks crappy , but i will posted a vid and pics of my rides and about 3 weeks i will go back to the dyno and bring a video of my beast... nice forum and nice number out there... GO Nissan!!!
