just out messing around... hpt showed a spike of 23.6 psi and even out at 21.8-22.0


just a stupid blox ceramic ball manual boost controller on top of a 14.7lbs wastegate spring!

I get some fluttering at high boost levels with the internally gated 20g anything over 19-20psi and it flutters

anyone have any suggestions of fixes for this?

im jealous- i wish my boost gauge would turn nearly a complete circle

 

i honestly think it wont go any further even though there isnt a needle stopping it it is burried

 

Weld the internal gate shut.

 

you made 2 threads?

 

could be the way the BC spikes, other than that, I've never messed with that setup. I know mine doesn't do that

 

first one was in the wrong section... i am used to posting there...

is anyone running internal?

 

just the hahn kit guys I think. I know on the srt's that happens with some MBC's

well, you can still enjoy this vid.

 

thanks i was chalking it up to that... especially because it wont do it at 20 just anything higher...

 

***** *****, son.

 

wow.

 

no that was last night with your mom!

look for video later! still uploading that one!

 

You worded it wrong. Fail.

 

When I mess around with boost w/o hp hooked up I always wondered if the needle stops there or not.

 

yeah i'v spiked 26psi before and the guage never went any higher than what i would predict to be 23psi if the numbers were to continue...

 

saved for after work

 

you are getting the spike due to lack of exhaust flow. i ran into this a lot on my dsm's. a divorced 02 housing will fix this.

 

Troof, But hahn's 20gs are set up to where i dont know how you would run a divorced o2 housing

 

spikes are normal for smaller turbos...when i was on my stocker,it spiked 21psi and by redline was down to 16psi...the spike gives u added trq,but barely any horsepower.its not a exhaust flowing factor,its the turbos capasity to make power and hold it till redline..big turbos have no problem with that

 

You do know we are talking about a 20g right?

 

your computer does that. not the turbo.

 

hey bro what comp pistons you running agian?

 

best youtube post ever lmfao !!!!!!

 

not really.my ecu has nothing to do with my boost..my boost is adjusted via the diablo,and it still kept getting the spikes..only real fix is big turbo
