Compound turbos on a 1.9td

[jimbobpolo]

It's 104.8 at the wheels,

R.O.R, your correct, after a quick call to the guy that gave it to me it turns out it is an eBay special! Haha it's gonna take pride of place on the top of my pile of scrap turbos! I don't fancy putting it anywhere near my aaz! I don't fancy bits of compressor wheel potentially finding their way into my engine!

On the subject of size, it is huge compared to my k24 and massive compared to my mates t3 on his type25 camper, so it's got t3 flanges but the compressor is about 20% bigger than a genuine t3.

Back to square one then! What's peoples suggestions for a LP turbo?

104.8whp --> 130bhp on a FWD car? Only in the UK

[RabbitJockey]

It looks larger because it's a 50 a/r housing

I do not understand why so many euro people correct the numbers to flywheel hp.  It's like all the muscle car guys here they always want to compare their Guestimated fly wheel to everyone else's whp.  Especially when they compare old factory numbers to newer cars,  before 1972 the hp was measured on an engine dyno with no accessories installed and completely different exhaust manifolds.  So that 500 claimed hp is probably closer to the 3-400

Becouse we are intrested how much power engine makes. Not how much power you lose to drivetrain. For example, transmission fluids will affect drivetrain losses. That has nothing to do with engine power.

[Alcaid]

But UK dynos tend to add more "drivetrain losses" than others to get happier customers

[RabbitJockey]

Yes but it is still a guess rather than actual power at the wheels.  And it also goes under the assumption that the drivetrain always takes he same percentage; and that the amount of power you lose increases equally with how much power you make, I know there's a thousand ways to skin a cat but to me my personal preference is I want the most realistic numbers possible

[Blocksmith]

Just the difference between how the car as a whole will perform based on the engine, as opposed to how just the motor as an isolated system is performing, I suppose.

[MJF]

Drivetrain losses are measured in dyno everytime. It's not just estimated value.

[jimbobpolo]

Anyways the power run was done just so I had a before and after comparison,
I still need some suggestions for a good LP turbo to use..

[Alcaid]

Your 160-180whp 1.9TD goal is easily reached with a single turbo with early spool and good efficiency. No need for compounds, compounds will only give you higher intake air temperatures, complicate the build and add lots of weight. Why bother?

[jimbobpolo]

Ive had a big single turbo but I want a compound setup, i already have a huge alloy fmic and I've never had problems with intake temps and I don't see a major issue with space or the weight of another turbo? It's easy for me to plumb in too as I still have parts left over from my previous setup.
I think I'm gonna use my k24 for the LP turbo as its to hand and I already have flanges made for it.
