HAS this ever been done? is it possible ? is it possible thru a single inlet and outlet intercooler or would I need a dual inlet?

gtfoxy

Durp (reading is paramount)

BoostedLS1CrownVic

what issues would be stopping me from building boost ?

gtfoxy

Wait. I misunderstood the question. Are those two different sized turbos?

You have both turbos running into a Y & then one outlet?

It won't make boost at wot?

BoostedLS1CrownVic

yes they are

gtfoxy

That's not a good idea.

What size are they?

from what i hear is that the issue would be the smaller turbo spooling up 1st and forcing it against the bigger turbo . is that correct .

gtfoxy

Ok, you are saying "T70". That doesn't mean anything looking at your turbo specs.

What is the wheel sizes on the 2nd one?

thats the other turbo

gtfoxy

You're going to have to contact them to get the specs or take the turbo off & measure it.

You never answered my question of does it make positive manifold pressure at WOT?

Secondly, you have to have the same A/R's.

If the compressor wheels are maybe a couple milimeters different, it may, may, work out somewhat OK providing the exhaust sides are identical. I wouldn't do it that way, ever, but it may work.

Why didn't you order another of the same turbo to begin with?

BoostedLS1CrownVic

im sorry. it does make positive pressure. i can post a video up in a second. and in the specs it shows different A/R's
And this is my 1st build i thought i order the same tubro by typing in T70

1 turbo

is that the enough

Need to know the compressor & turbine dims on both.

The big issue is turbine sizing, providing the compressors are even close to the same. That changes airflow & pressures across the side of the engine it is connected to. That requires different fueling & timing.

BoostedLS1CrownVic

sorry this is all the specs i can come up with

gtfoxy

Like I said. Take it off & measure it or contact the company.

Plus you need to have at most .68 A/R turbine housings unless you have one heck of a high-flowing motor.

BoostedLS1CrownVic

well from what i was told since one is a .84 and the other is .96 turbine housing, that these are a big difference and not really close to each other

BoostedLS1CrownVic

correct me if i am wrong but the main issue with having 2 different turbos parallel with each other is that the turbo that spools up 1st will push back into the weaker turbo.
