MP70 vband fitment issues
 

vband isnt sealing with the master power t70, the pics tell the storry
anyone else ever get this problem with the MP70 and what could be done
there are a few options but i'd like to keep it clean looking, instead of clamping to the turbo i could extend with some pipe and use the 2 vband flanges, i was also thinking maybe to trim the vband itself on the one side so that it would sit in the groove of the turbo to seal up

thanks for the help in advance

oh and would/does it matter that the flange is 1.5mm larger all around?

yah it matters if its bigger it will never seal

Re: MP70 vband fitment issues
 

Turbo vbands are generally different from regular 3" or 2.5", etc vbands.

Give me some dimensions like OD and ID. I see if the precision turbo ones are similar.

Re: MP70 vband fitment issues
 

well the vband is the 3" ss, pretty standard i think as for the turbo

Re: MP70 vband fitment issues
 

On the precision turbos that we use, a standard 3" vband is way to big. A 2.5" is closer to fitting, but then you can't use a 3" on the outlet.

Like I said, there are special Vbands for use with turbos that allow the right size piping.

2.5" vband clamp won't fit will it? the outlet is closer to 3" i dont think you would be able to even put the vband on properly

if youve got any leads on where i can get these special vbands let me know

Re: MP70 vband fitment issues
 

Okay I measured a precision turbo 3" v-band and the OD was 92mm, exactly like yours.

The ID is about 2.875, slightly smaller than 3" tubing. The tubing slips over a small lip on these v-bands.


I'll try to get a pic.

Re: MP70 vband fitment issues
 

yeah my tubing fits snug on the vband flange, theres the little lip like you said
but its the seal on the turbo that's no good

Re: MP70 vband fitment issues
 

NO I mean the tubing fits OVER the vband.

Re: MP70 vband fitment issues
 

try to get a pic cuz im not quite understanding
i just need to know if i trim the inside of the vband or do i extend the housing with straight pipe and use 2 flanges instead of clamping to the turbo housing

Re: MP70 vband fitment issues
 

still looking for info

Re: MP70 vband fitment issues
 

Okay so looking at some precision vbands at work today, I found this. The 3" one will not work. Way too small as it is meant for T3 turbine vband housings.

The T4 one uses 4" tubing, but the OD is 92mm. so it will line up perfect. The ID though was like 78mm or so. It tapers down from the 4" tubing.

Re: MP70 vband fitment issues
 

so your saying i need to get a 4" vband set for the turbo housing? hmm, that doesnt sound right, can you get pics to show me?
its just that damn vband edge that catches onto the turbo housing, maybe if i trim it with a dremel? otherwise ill extend the turbo housing with some straight pipe and use both vband flanges

Re: MP70 vband fitment issues
 

No you need to get a T4 vband flange which uses 4" tubing to connect to it. Regular exhaust tubing flanges are generally different than turbo vbands.

T3 vbands generally use 3" tubing and T4 vbands generally use 4" tubing.


The OD on the precision T4 vband is 92mm, exactly what you posted.

Re: MP70 vband fitment issues
 

then i would need to get a 4" to 3" reducer, cuz my entire exhaust line is 3"
