Anyone ever do this or have any thoughts? 2 cylinders feed one and 2 for the other??
-
I am pretty sure Dave @ PP did this once, just for something to do. Not sure what happened to it.
-
i think it sounds cool... its alot of plumbing though haha. probably would make a nice whistle and good power
-
something's in the works, maybe this summer.
-
Sounds like an expensive, frustrating waste of time that will give about the same results as one turbo of a slightly larger size. Then again people have told me I was wasting my time, like trying to put a VW Diesel in a Land Rover, so go for it! Just share your results, good or bad.
-
why would ur vw swap be a waste of time? its the best motor ever
-
Because they didn't think such a small motor would have the power or torque, plus no one made an adapter for it or even knew if it could be done.
-
oh did u say the stock motor had like 40hp or something? haha i think its smart to put a newer more effecient motor in. probably easy to get parts for it to
-
Yeah, 42 hp, though parts are surprisingly easy to get for it. Did you know that over 70% of all Land Rovers ever produced are still on the road today?
-
Yep I did this about 2 years ago, worked great, no idea what happened with that engine/car, haven't talked to the customer in a while. Can't say it was really a lot better than just going with a MB t3 turbo, but it was fun to fab up.

Aaron, you really really need to worry about getting your crank fixed before you go about doing any more modifications.

nope, not talking bout my car, not putting much more money into making this car go fast, if it'll run reliably, i'll be happy. Running tough again, getting it checked tomorrow, injectors or crank. We'll see if the timing's changed.
lets not threadjack

Not trying to thread jack, I just don't want your valves and pistons to meet and make a mess :shock:
Hopefully your crank gets fixed. :)
I think there is a guy on tdi club running twin ko3's as well.

Parallel twins are pretty pointless on an inline engine. An appropriately sized single turbo will spool just as quickly and a single VNT will walk all over a set of twins.
There are only three reasons to use parallel twins on an inline diesel engine. 1- To make yourself seem cool. 2- To make people think your car is fast. 3- There isn't a single turbo big enough to supply the air the engine needs.
If its for a S&G project, have at it and have fun. If you are serious about it, your efforts and money would be better focused on a well matched single or a VNT.
Personally, I'd rather get a few of those IHI micro turbos and have a turbo for each cylinder.

Until the vanes seize up

Never had this problem :shock:

Bla, I hate vnt turbos, they don't flow worth ***.
Don't get me wrong some of the really knew VNT designs that are starting to pop out in the last 2 year are pretty decent and you can actually flow some air through the turbine, I think the newer audi diesel 3.0 liter engine has one of these turbos as well as the porsche 997, but the crap found on vw tdi's are just that.
-
As for parallel twins on an inline engine, I would agree that with a split turbine housing you would be better off running a single, but if you were stuck with a single tang housing, than its going to be close to 6 of 1 and a half dozen of the other. Obviously twins requires a lot more fab and that should be factored into the undertaking.
-
I just put this out there to see what people thought. I have the same idea that flow is flow. 1 big turbo or 2 small ones does not make much difference. I guess we are all in agreement. I was hoping someone would give a reason for doing it that I did not think of. Guess I was right in thinking this way.

that would be pretty interesting... talk about complicated, but the possibilities...
-
Twins apparently work on an inline or there wouldn't be factory engines with them.(ACERT CATs) Thats not saying they are worth it on a small 4cyl VW. VNTs are great they are just in the early delvelopment.

Those are not twins, they are compound turbos. Compound and series are very different from parallel twins.
-
Yes your right. oops
-
No: 1, 4 cyl for 1 turbo, and cyl 2-3 for the second? a lot of fun to find a place for this set-up, but I found that It's a nice and original set-up.
