Tuning turbo time!

Know you prob did a test piece but hows ur penetration on the ss? if it was me personally i wouldnt be worryed about dressing it id be more inclined to know the weld was decent and not going to crack under heat etc as you can gt a weld to look decent but it can still be **** weak, just a thought as i know on the coupe ss manis theyve cracked around weak welds?

in theory, yes. That is why some high end cars have swivel rose jointed fancy turbo hangers.

In reality, not really. Having got a great insight into the drift world, where 99% of people use one or two solid manifold braces, I'd say if your manifold is ok, you position your brace correctly, and your engine mounts are ok, then a solid brace will be 100% fine!

There is no other motorsport that puts as much stress on car parts - drivetrain, engine, mounts, turbo, exhaust, etc etc, if drift cars work, then any car will.

I havent got a pic of mine - all it is is a small bar that bolts to the block and the turbine housing, to stop the pull from the exhaust through engine movement.
 
how would I go about with bracing?
surely if i weld a bar from the turbo flang and onto one of the many unused bolt holes on the block (aircon) then wouldnt the manifold expand with the heat and the brace wont and so make it more likely to crack?

That'd be my view, anyway. The correct way to do it is to build a tripod mount which is rose jointed (the roses needn't be anything special). Thus, the charger is supported and free to expand in 3 dimensions, so you can't get cracking (or at least stress related cracking) at any point. You can probably pick up suitable stainless tube for next to nowt -- it's not as if you'll need a lot of it.

Drifters? Oh dear.............:yuck:
 
interesting stuff... came up with something differant though which I seen and makes sense to me...

simply mount the turbo down pipe to the engine... do it so it supports most the weight of the turbo... but mainly it isolates the turbo from the rest of the system.

the manifold expanding won't be a problem as there is more then enough flex in the thin wall down pipe.

and best of all... cinqs have on bolted to the back of the engine as standard... just need to find it... beef it up... make it work with my exhaust
 
Drifters? Oh dear.............:yuck:

hmm. So just because you're narrow-minded enough to look on a certain motorsport with disdain, it also means that the lessons learnt from it are also worthless?

We arent all F1 snobs you know. Rose-jointed turbo hangers are relatively uncommon in street tuned cars, unless its a cossie :rolleyes:

maybe I need to stop thinking!... but ...does this sound like it would work regarding oil cooling?

if I get an alloy sump for my engine could i weld into it some thin wall alloy pipe with a bore of about 2mm in a zig-zag or even a spiral around the bottom of the sump then run coolant into the pipe directly from the radiator outlet (tapped into the pumps intake) then outlet into the coolant tank return?

doing this should mean the whole system is self contained on the engine and would mean no need for an oil thermostat. the other benefit would be oil that reaches working temperature much quicker.


Got the idea from these http://www.elise-shop.com/images/large/WOCLOW_LRG.jpg
which seem to be getting a popular alternative to a normal oil cooler
 
fingers... is this the kinda thing your talking about?

Exactly. Hardly complex or fancy, methinks, and it does stuff the others can't.

I'd also do the old drill a hole and hacksaw trick to the exhaust manifold flange -- essentially it'll allow for expansion there without cracking or distortion, and it's absolutely free.

I can see a certain appeal in it, just as I can for autotesting or trailing. But if God had meant cars to get that sideways she wouldn't have invented mid engines, FWD or 4WD (or would have bought big shares in a tyre distributor). I can't really think of F1 or drifting as motorsport. As with trailing and autotesting, I can see useful skills being developed there, but can't see much being learnt of use for other motoring activities from an engineering POV.

I think of myself more as a moto GP snob. But correct engineering is correct engineering, wherever you fall over it.
