I'd rather put a lot of money into my 2.8 and have a totally original powerful car then do the 1.8 mods that everyone does. It's not like its any differant from any other engine but its just a little limited on space. But if someone built the bottom in and put a little lower compression piston in then put a bigger supercharger then the pes i bet you could get to 400 hp and still be reliable. Of course it would be a LOT of money but it could also be magazine worthy!

 

there's a 2.8 section in the newbie guide. guess i should add some more to it.

bottom line is, unless your willing to drop some serious coin, nitrous is the only worthwhile mod

 

Cant add any more to the guide after the forum switch. There is a max character count for posts, and it has been exceeded. You'll have to do it another way if you want to add more. **** if you want you can take it uppon yourself to create new 2.8 specific sticky. I don't have the knowledge or resources to put a good one together. I was asking people to send me stuff, and some did, but what it comes down to is where to source the hardware and tune to support a turbo(s)

and welcome back!

 

Well when you want to talk finances it's not always feasible for someone to take the plunge and go buy a new car if the 2.8 is what they have.


I won't go into my finances on the internet but I don't have the available capitol to pick up something new and be back in payments right now. I traded a car I had to get the a4 I am driving right now. I have the cash to do the maintenance it needs but that is not the same as having a car payment and having to pay full coverage insurance on a car with a note.

And if someone were to do this in stages, piece something together it becomes much easier to stomach. I maybe have ~$300 extra per month to buy a new piece to the puzzle.

You could throw together a 5psi unintercooled kit for ~$3-4k, I believe. Then add on some more bits later to take you to higher boost. Eventually rebuild the bottom end with forged internals and shoot for the moon if you want to go that far.

That being said I am smart enough to not dump money into F/I on something I don't have any backup funding to replace parts that break. I was just going over potential options.


I was just looking at the PES s/c kit. I am assuming their 295hp figure is a calculated bhp number? And their site doesn't say, what boost level are they are to do that? It looks like the kit is completely unintercooled so it can't be much over ~6psi?

 

Does anyone know why they went so small on the s/c sizing BTW? mp62 seems awfully small for a medium-displacement v6. I would think you would use an mp90 to give yourself/customer some head room if they wanted to build the bottom end?

 

Right the pes sc is around 8 psi I think, maybe 10 with a different pulley. Their advertised hp should be at the crank.

The point is, you cant just say "turbo it" or whatever when someone is looking for more power out of a 2.8. The better thing to do is first ask if their checking account is bloated.

 

What are the engine management solutions for the Audi?

I see what I think is a lot of people talking about ecu tuning? Is there and end user tool that can do this like the Cobb unit for the scoobies? Are there shops that have this capability?

 

If you plan and design well, set a REASONABLE goal for the equipment available to you there is no reason you need to have a bloated checking account.

Am I missing the intercooler in the PES kit? How would they get away with 8-10 psi unintercooled?

 

if you want the best of everything. Yep, you'll need a bloated checking account but that is not exclusive to this motor, or this car.

 

You mean for the 2.8? Other than a N/A chip that a couple companies offer that just tweaks the fuel and timing a little, and whatever PES offers with their SC, I have no idea. I'm pretty sure you gotta get seperate management from the ECU to accomplish anything more than those 2 things.

Are you considering the limited amount of space you have to work with as far as modifying manifolds and mounting a turbo(s)?? The 2.8 is crammed. Unless it's a rear mount, you are going to have a bitch of a time making anything fit close to the motor.

We don't have hardly any SC 2.8 members. Info on that is not so easy to come by around here. A supercharger isnt creating the heat that a turbo does, thats one reason an IC isn't necessary.
