Looks good.

350 is weird.

I'm at 400 at 13psi on a garrett t3-t4e

 

my 5857 ball bearing is at 422 on 13psi......... mase ftw


350hp @18psi seems off

 

Motor has low comp on a cylinder or two maybe? Shit I'm making 360 at 9psi with a Comptech. Something definitely not right with 350 at 18psi.. I don't care what dyno it was done on. With a good tune he should be making that with half the boost

 

well I have 3mm hg, clutch was not slipping I don't think. Can a log manifold really be designed that bad? I'm gonna run a compression test and go from there.

 

Maybe he should swap out for a pfab manidold, looks like it would fit around the same spot.

 

DING DING DING!! LOL

 

Don't do the Pfab Log that is a pain in the ass tight Fit 1.5' clearance just finished my install yesterday quick spool tho!!

Here's my Build

 

call the place that made the mani and tell them to redesign that junk!

 

IIRC this kit was bought used from a local shop here in Tampa. I know the builder of the manifold and he doesn't fab his parts with power in mind, more geared toward simplicity and reliability. I'm not surprised his setup doesn't make the numbers it's 'supposed' to.

But I caution everyone not to get so caught up in the final numbers and feel like the car doesn't perform. Alot of you seem to forget that 350whp is still good power regardless of the psi. Oh, I have personally seen that turbo on an "efficient" manifold and world renowned tuner make just under 400whp @ 20 psi! Until you see dyno charts with psi overlay, don't believe everything you hear or see

 

what does the manifold look like?
who made it?
