Talking 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 ****** 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 , all my efforts have been amply rewarded .
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 ?.

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 ***.

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 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
