Don't have the exact sizes on the turbos, Jose and Jason are the guys for that. I can look it up in the morning though. As for spool up the TC and T series units spool up FAST for non BB units and will outspool the GTS. I have seen 200rpms sooner on a twin Viper that was tested.

 

What'cha gonna do with it?

 

Throw it in the river

Which is spanish for, its yours if you want it.

nO ITS NOT.... MAN I NEED TO TEACH U SPANISH TOO.....


he's got a daddy named forrest too.....

 

yo tango err..muy grande camshafto...no es bueno???

Is that right

 

You damn coconut!

 

shhh..."they" are watching....

 

so have you figured out the problem yet?

 

shhhh those who u must not speak about might be listening......



Spanish is getting a lil better we will work on it.....

 

I didnt say the cam was his 'only' problem, just may be contributing to the overall problem. Things are a lot different at 5000' then 1000' elevation, its hard to compress the air if there isnt any

Did you try it without the air filter out of curiousity?

 

Yeah put a screen on it with the same results. It was one of the first things I tried since it was one of the easiest things to take off and check.


redcobra, nope.

 

go ahead and put a block off plate where the wastegate is to eliminate the gate itself from being bad... should be simple enough.. piece of 1/4" steel from lowes and a drill and grinder can cut a rough plate in a few minutes... let her rip!

lol. you just want to see if it is the turbo...



I thought in your other thread when you bypassed the MBC it boosted up to the spring?

 

Not sure I follow where you are going with this, but yeah we did that and it worked, cracked the WG open to the spring rating of ~11psi. Figured it was the turbosmart boost controller messing up, replaced it with a new hallman MBC hooked up either way (top port and correctly at the bottom port) closed and cranked fully open, only boost to 9psi. Do you think the WG is bad?

 

Maybe I'm missing something here. If you removed the mbc and were able to see 11psi and the gate opened on spring pressure, then everything there seems to be ok. With the mbc hooked up you could only get 9psi? If the gate were bad or you had it hooked up wrong somehow it would seem that you would still see 11psi but the gate just wouldn't open.

 

Yeah, thats why i'm having such a hard time with it. Hooked straight to the compressor cover to the WG side port, no BC at all. it'll crack it open and hit ~11 psi. I wouldn't have spent 89 bucks on another BC if I didn't think the turbosmart one was bad.

What do you guys think....that i'm leaving out info for some reason

Now I have two good BC's and a car that won't boost up with either inline, no matter how much they are cranked open.

Breakdown of what I done to figure this out.

Removed BC
Bought a new BC, same
Removed air filter
Removed and checked IC tubing for holes
Removed all silicone and check for tears or pinholes
Replaced all T bolts with new ones
Removed the crossover and put a fresh bead of high temp copper RTV on all flanges

Can't make more than 9psi with a BC new or old hooked up.

Haven't been able to pressure test the IC tubing and IC on the car because i'm working on another project.

 

Just a thought. When you say you hooked straight to the compressor cover to the WG port and saw 11psi do you mean your guage showed 11psi or that the WG opened? You should loose somewhere in the neighborhood of 1psi+ between your WG and let's say vaccum at the brake booster. Where is your guage tied into? Have you tired to hook the WG to the same place as your guage?

 

do you think the BV is bleeding off presure?

Might be i'll get a good read on it when I pressure test the IC pipes from the turbo to the TB. It'll be pretty evident where things are leaking then....if they are.

Bird O' prey,
Guage is inaccurate, its only your basic boost gauge, reason why I put ~11psi, its a lil less according to my HPT logs. I should be losing 1.5psi through the IC and tubing.

Gauge is tied into my brake booster line, I have all my boost ref stuff ref'ed off of there with the exception of the WG line.

No not really.. I hope to god its not and am doubtful it would be.. I think it may be in the wastegate if there are no leaks found elsewhere in the preturbo plumbing on the hot side and none in the IC. could be the valve seated wrong.. not sure what gate he is using.. never answered my question on it. I know on my HKS 40mm wastegate, the sealing seat is actually on the flange and I have set that bad boy on there cocked funny and wow did it make a difference. the first gate I tried using was one of those 50mm HKS knock offs.. never again will I waste money on jumk.. it was useless for the 200 bucks I spent on it.. that was a long long time ago when I first started the build and was ordering parts.. so i ponied up for a real 40mm HKS unit and my problems were solved, it is a non adjustable wastegate and I am fine with that! seems like the more gasgets ya have the more things go wrong.. so I have a variety of springs I have tested, one for 10psi, 14psi, 18psi, 22psi and one for 27psi. I usually keep the 18psi spring in it and attempt to use my Greddy profec B to raise boost.. I have one setting right for the high boost and it will hold 23psi very steady.. I will say using the BC it spools to peak boost alot faster as I have it set to hold pressure on top of the diaphragm until right at 21psi.. so the gate doesn't budge until it references 23psi from the compressor housing... this equates perfectly to 21psi where I can hear it begin to open then she settles right on 23 and holds steady.

god all this talk of it makes me want the car back on the road!!!!!!! hurry up 401K withdrawal check dammit!!
