T04B V-Trim SLLLOOW Spool

You guys also have higher compression but your right, it still shoulden't spool this slow.

I myself had a t04b v-trim with a t350 turbine and a garrett t3 .63 a/r turbine housing, external wg, and a sfp manifold and mine spooled to 22 psi by 4k. With the mitsu housing, I would hope that it spooled just a little faster. I almost bought a bullseye 60 trim earlier this year but decided not to. I ended up going with another vendor and Im almost glad I did. Only problem from them(I wont mention names) was they sent me a different turbo than what I ordered.

So im not the only one wondering whats up with the spool. I got OK spool (16 psi by 3800 rpm in the begining), but since i wasnt satisfied i shortened the arm to keep the flapper shut, because the turbo would built 10psi then the flapper would open prematurely and slow up the spool until 4500rpm. NO DIFFERENCE. I get full boost 17psi by 5200rpm, after it settles back from the creep at 5000rpm.

Apart from the creep, this slow spool would explain my bogging at the track. Anything below a 5500rpm launch is a 2.5+ 60 foot time.

I am now considering an external setup.

I have had ZERO issues with Bullseye, minus the crappy mani/turbo gasket blowing out. Evo gasket fixes that. Spool? No spool issues either. Used the anti-lag deal with DSM link... hasn't killed the turbo yet and I'm boosting right off the line. Not sure what to tell you guys, I'm in love with this turbo.

the turbo does spool slightly slower than i wanted it to ,but i get 22psi before i hit 4000rpm, which is just about right i guess


who knows...its not bad on a fwd
