dumpvalve not dumping and no boost on gauge
Turbo Mini Forums

hey

i currently have a blitz super sound with a soft spring which isnt dumping at all, its connected to the plenum with a boss and a hole drilled in it, with this dumpvalve it has a vacuum take off which i have T'd into the boost gauge, now when i rev it a little the boost gauge goes into negative boost, and ive checked the gauge works as ive had a foot pump on it and it does move

im guessing that ive connected this up incorrectly as the boost is going into the vacumm port on the DV holding it shut and not getting to the gauge?

this is the fitting guide http://www.blitzpowerusa.com/techsupport/p...v-universal.pdf

it is saying that it must be connected to both vacuum and boost before the throttle body/carb?

sorry if im being a bit dull haha

thanks guys

Is this on the move or are you just sat revving it on the driveway?

What that's crazy, you go commando hahaha! How heavy is your helmet ?

post a picture or draw a detailed schematic of exactly how you've it plumbed.

Pictures would probably be better.

But if you're making no boost there wont be anything to dump

And yes boost would hold the DV shut under normal operation.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Standard recirc stuff disabled in plendidlium and throttle disc?

I'll guess that the vacuum pipe is connected to the take off on the carb intended for the dizzy vac advance which is the wrong side of the butterfly.

And it'll make next to no boost when revving on the driveway.

In the 13's at last!.. Just

Ah yes good point and make sure u have right strength pipe and right size of hole... i had it once where the pipe was sucking itself shut

Nice and clear diagrams for the plumbing by Ben here:

Ahha that what I think I've done!!! Put on the vac advance take off hahaha

Also this is on the move not sat still haha

Will drill and tap another take off next time the manifold is off

If you're Using the metro turbo manifold, just take out the banjo bolt for the servo and drill/tap that.
