Ok wasnt sure where to post this but decided to post here since it'll get more attention. Anyway... I'm running a hx40 in a bep housing .55 and I've never really taken notice myself how laggy it was until ppl started pointing it out to me after looking at my logs. I just assumed it was normal to be laggy being auto with a stal .
So my setup is stock 7bolt motor recently reringed, 155 across the board, leakdown test was good showing 12% at most so the motor is healthy. Evo 3 intake manifold, bc 272 cams, mild port on the head, knife edged and gasket matched intake and exhaust, Old slowboy racing exhaust manifold with tial external gate on the manifold, 3" turbo back to apexi muffler, vrsf fmic.
Transmission is stock besides translab shift kit and forced four shift box with a sinister draginator 9.5 converter.
I've checked for boost leaks and only one is a very minor leak at tb shaft seal which I just rebuilt cpl weeks ago but its leaking ever so slightly. Being on sd I wasnt to concerned about it.
Driving from a roll i dont see full boost 32psi until 6300 rpm. I've tried brake boosting from a roll and still doesnt seem to bring full boost in any sooner. Maybe 200rpm sooner.
But from a dig with 2step set at 5500 and antilag enabled at 3500 I can easily build 20psi even more if my brakes could hold back more in 2.5 seconds.
So idk if it's the turbo to blame which it shouldn't be or the stall to blame or something else I may be missin . From a lot I've read I should have full boost almost 1000rpm sooner on an auto and 5spd guys I've seen having full boost as soon as 4500rpm.
I'm currently at work so I cant post a log but I will try to post one on break or after work or tomorrow.
