Quad turbo.. Any chance on a B6.

[jhntu]

Thanks advance.. As much as i thought it wasn't such a bad idea, some people seem to think not so much..
Like i said.. Many ways to skin a cat, same old knife.

I honestly wasn't even aware of higher end cars using this as their basis for cooling/cooking as some might see it as a little unothadox.

I honestly just thought, makes sense since there is a continuous vacuum and the fact it's reacting with what the drivers intent is.. To move the vehicle from a to b in the fastest time possible whilst keeping the thing as cool as possible, whilst reducing a reintroduction of heat back into the system.. Leave the engine to breathe.. Whilst keeping the engine to a regular intake of heat and lead the maximum heat to the external side of the car and being there is an unutilized source of cooling available.. Why not.

I hope you have a tig and can use it well....is this possible. Sure.
I say do it. I'd go a different route if you insist on multiple turbos. Like a pair of smalls compounding into one large one.
Cost of doing this will be insane. But hey its your money
Good luck!!!!....out before damkid starts sending me PMs

Finding 4 identical turbos that are sufficient size, is going to be interesting...and expensive

Supplying oil to them is also going to be interesting

As will the sheer fab work of fitting and plumbing them

Isn't there a pretty drastic loss in efficiency when you have only one exhaust pulse going through a turbo?

A pile of turbos on the front of your engine is going to be colossally heavy, and in an area where the weight is going to have a much higher penalty

Yes, on everything.
Single cylinder engines have a drastically different turbine requirement. They seem to benefit from large turbine wheels with aggressive trims and small housing aspect ratios. When properly set up, the lower efficiency is minimal, but most chargers aren't designed for this application. The cost to build an engine like this that actually works well will be astronomical, even with a full machine shop and acess to Garretts entire catalogue of components. It would be a work of art if done properly and would sound like nothing else.

Thanks kornhead..

You're also a great source of inspiration too..

Being b6 seems to be an underestimated darkhorse in the scheme of things in all terms racing, I'm guessing unless setup properly setup, wouldn't be able to handle such a large engine as a 2.5l and from what I've seen with the 2.5 on the quarter, seems to have a lot of issues handling traction in 1,2 and just in 3rd.

Even the 1.8l seems a little bulky, but for the sake of argument, may be able to handle a lot more output and possibly not even be a struggle compared to the 1.6 or 2.0

Even then, we haven't even discussed transmissions.

E series is out, unless within the 150hp range.. I've read up to 170hp, but usually grenade.. Me personally, would have used a stage 3.. However, if it were a stage 3 they did use in the e series and boomskies, would have stepped up to the G series..

I can only imagine it would too.. Response like within a whisker of touch of the throttle.. The familiar whoooizz on the straights.. Hrrrm cause racecar..

[Advancedynamix]

The throttle response would be worse than a good single turbo setup, but midrange and top end could be improved. The Z series engine would be a better candidate, or the b6d from an mx3. A typical b6 head will be a restriction long before those flow numbers become necessary.

This is why i insist on the like system.

Well, we're not all going to go to that extent.. But, i will say this, get 4 turbos suited within the engines suited rev range and we have something.. I'd choose highest to lowest between changes as being higest will assist the lowest.

[koRnhead]

You can't just pick 4 turbos for the engines Rev range. You need to think about how much exhaust will be flowing into each one......so take your 1.6 and divide by 4.....if you're going to try and run them directly off the manifold. That's what you're going to be spooling them with. So you're gonna need some tiny turbos.
Now if you change to a compound route that will change. But as has been pointed out. You will have a large fab budget even doing the work yourself.

[jhntu]

Ok, what turbos would be in the acceptable range? being they'd have to moderately small, i figure, something to suit at least a 1 litre.

Something similar to this..

[koRnhead]

Yup ^^ something similar to those. Really using a BP for this would be better. You're going to want all the displacement you can get!

[bhearts]

I'm all for crazy projects, but this is it outlandish. There's just simply no room, or anything to gain over one turbo. Unless you're doing sequential turbos. Or a twin charged motor

[bhearts]

The twin charged build is pretty much the best idea ever. You could spool a gt35 turbo at half the rpm with a supercharger running 15psi.
