Well as far as physics goes, the farther you mount the turbo away from the engine the more lag your gonna have, the way to combat this is to use a smaller pipe, and using a smaller pipe reduces horse power output..............................so 350whp+ is a fantasy.

 

what part of the world do you live in where it's cool to have your turbo in your undercarriage?! that would NEVER fly in New England. I'll tell you that!

 

Well if you email Anthony, he was able to get to 320HP to the wheels. He dynoed his car, the only reason why hes not there now is because of timing...he dosent have a Stand alone ECU yet, and its almost impossible to retard timing without a stand alone ecu on these 96 audi a4's.

And actually, rear mounted turbos are starting to get around in the racing world, they have many pictures on their websites of race cars using their turbos systems and how there systems are helping them in the long run.

As for STSturbos lag, the breaking point for power is around 3500 to 4500rpms debending on where the turbo is mounted but either way the 96 audis rpms rage is 6000rpms. I have a friend who use to have a VW jetta, he had a front mount turbo and hes breaking point of his turbo was only about 2500rpms away from his shift point...

You would have to talk to a STS rep. they will explain alot better then me, there not better then a front mount, but they are quite good for a rear mount. Anthony with about 280HP right now or so...has had good boost. On a serious note man, email STSturbo.com they will explain how their turbo system is better then others.

Heres an image telling people what comes from having their turbo systems... Its not an Audi but from emailing them a while back from trying to get information it does depend on where you mount it...but eith way you can make as much "POWER" as one can handle with their twin turbo setup. Basically you can make as much power as you want just like a front mount only thing is..."ITS IN THE REAR"

 

manI don't mean to burst your bubble... but don't waste your time on the 12v motor. Seriously. 1sika4, If you'd like, I just PULLED OUT my 12v 2.8, and you're apparently getting ready to rear turbo yours. we'll have a contest:

Your 12v rear turbo vs. my motor swap & build. we both have 96 a4s.

rules are simple. end dynos and receipts, and the one with the most HP / dollar / time ... wins.

 

Cool, and yours won't have a nut sack of a wastegate sticking out the rear either.

 

^^^+1

 

LOL.... well if all else fails, we could have a "drive through puddles and speedbumps" contest too.


**edit - I was going to leave the rear moount turbo thing alone until he posted a digram that lists "amazing turbo sound" as a benefit.

Haha, acutally im not going over 350HP, if you read my post i dont wanna go over and i dont care about "MORE" HP so you will beat me regardless, this project is not for people who wants 400HP+ its only for the people who want power but not much like me. I will be fine with my 350HP so i dont care about how much power either one of us will push out lol

I understand that it wouldnt get much power but like i said i dont care so either way it works for me...

And also, thats from the ststurbo.com so you mock them not me...its all because of the rear mount? if it was front mount none of this would be going on, but the problem is, there is no turbo that fits in the front of the v6 motor unless your willing to spend more money....

ALSO I HAVE A FWD CAR!, i dont wanna be spinning none stop in 3rd gear with 500+HP...

 

Supercharger fits up front.

 

yeh but they dont make it for the 96's only because the Hitachi ECU is unchippable, "said so by the company them self"

ANd as for puddles and speedbumps, FWD Audis have room just infront of the rear axle, speedbumps = no problem, water on the other hand is a problem...But i plan on having protection covering my turbo but only to a point i cant go into deep water puddles but others are fine

We might as well stop going back and forth, everything you say i have a solution for or something to stand by...My friend with the other Audi with turbo v6 goes to the forums http://www.audiworld.com/, and hes told me theres abunch of people fixing up V6's there and posting about it, i think i will get more love there
