Volvo K24 turbo in audi application.

Sure, as long as your spring has not been wound down and other silly things.

Thanks, wastegate appears and acts stock, gives correct boost with n75 unplugged.

Just might need to stick the 7400 on as my stock turbo appears to be dying

The volvo turbo has some kind of vband outlet





Does anybody have any simple home DIY ideas for getting a regular silicone coupler to attach?

Will the turbo "coldside" get too hot to JB weld a sleeve inside the outlet?

Failing that how hard is it to MIG weld a turbo coldside at home?

Or just cut off the vband and clamp on whats left?

if its ally you can't MIG it. Can't you just trim the lip so you can get a silicone hose over it and then clamp it on as per usual

[Ruffiano]

yes the earlier models of this turbo had the v-band, later were "standard". My thoughts are you could grind it down and then fit over it, you could get the v-banded part and use the v-band hose and cut it off and use that pipe for your standard coupler.

fit something like this...

Where is that clamp assembly from? I'm going to fit the volvo turbo too?

Thank you for the ideas gents

Why not? I know I would need wire, plastic liner, gas etc. Or would I just not be able to get enough heat into it?

As you say welding alloy with a MIG is possiable with the correct wire, gas ect, however it's REALLY tricky and it will never be as tidy as TIG.

[Error404]

you can do it with MIG, but for somethign like that it'd be really very very difficult IMHO. You need argon. The wire is really soft so you need a teflon liner to get a smooth feed, plus you want to use a large diameter wire which is stiffer to help with feed, but most DIY MIGs can't handle anything over 1.0mm. Ally conducts heat very quickly compared to steel so its hard to see the weld pool before it blows a big FO hole in the work. Then its a circular piece to weld which are tricky anyway!

Just a little update, winter is here and temps have been considerably lower, and car has been running noticeably quicker as well... So much so that i put a window in my block:



I guess stock rods with 450ftlbs+ of tq at the crank is perhaps a bit much for them. I already have a set of DM forged rods and another block to throw them in, hopefully will have it up and running in the next couple weeks, then we can up the power a bit more and run some e85!

[Billman]

ouuuuchhhh. What where the conditions? Mapping?

[Rocco]

puff¡¡

i am sorry mate

was your engine missfiring?

[Ruffiano]

no actual logs of it at the time, conditions were 30psi, freeway pull from 90mph= bent rod/ block window.

That's not rods, that's knock.
Exactly what happens when you have no knock feedback at all and run too much timing/boost.
I have mapped 10+ cars now to run 450 ft lb on stock rods, oddly enough, none of them have problems
