Did a bit of tuning yesterday !!!
 
After working out all the damn gremlins I finall got to do a bit of tuning , boost was up to 15 psi and rpm's up to 9000 , .......... I couldnt believe it , when those bridges begin to "open up" it sounds like V-Tech on those shitty Hondas , it now pulls so hard that I get fuckin bummy and have to let off the gas before I even get up to 7000 rmp (my tuner kept cussin every time 'cause he wanted me to go right up to the rev limiter @9000) , The "BIG BOY " spools like a puny T04 and whistles like a bird..........., I'm in love all over again:D , all my efforts have been amply rewarded :D :D .
Now I cant wait to get past 20 , then 25 psi !!!!, but before I do , the A1000 seems to be close to its max capacity (already) , my duty cycle is already at 88% with an a/f ratio of low to mid 11's in boost , I am using 4-850cc's and 2 - 1300cc 's , I am thinking of changing out the AEROMOTIVE for a pair of BOSCH '044 pumps , any one using these with a big single (high HP) setup ?.:cool: ;)

Marcel, I am using the Aeromotive with a T-72. @ 22 PSI I hit 97.7% but was a tad rich. What base FP are You using? I ran 18 PSi with no problems, never any pressure drop but I think as soon as these big singles start to get in their eff. range they start to use a ton of fuel. I finally got My car half decently tuned this Summer and I was feeling the same way as You. Wait untill You hit 20 PSI You will be amazed, I only am running a large street port and it still kicks You in the ass.

Good Job

The dyno graphs will come a bit later when I can get up to at least 20psi , its sorta expensive to go on and not be able to do much 'cause of a maxed out pump

Thats what rotor ownership is all about, being in love with it just for the fact of how damn fast it is and the sound :D Now I'm goin in the shed to finish of mine.

Its updates like this one that help all of us to get back some motivation when a upgrade "stalls" thanks Marcel

No problem RICE , .......been motivated by others in the past myself , its nice to be able to return the favour.
A bit more info for you guys , max exh temp was 1440 deg F (782.2 deg C ) , max coolant temp was 180 deg F (82 deg C) and max intake temp WITHOUT W.I active was 95 deg F (35 deg C ) , I LOVE my NPR large ........ wonder how low it will drop when I enable the WI ? , max advance @ 15psi was 12 deg from 6000 to 7500 rpm .
