Volvo K24 turbo in audi application.

It seems that this happened due to very lean conditions. The timing map looks ultra safe.

who mapped it then? what a bad luck..

[A80Avant]

tough mate,

check the map before making any assumptions about ECU Dmitri...

hmmmm

@Ruffiano
do you like to share your config file?

[prj]

Vems.

[Billman]

What ECU was he running?

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

[Ruffiano]

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

[Rocco]

puff¡¡

i am sorry mate

was your engine missfiring?

[Billman]

ouuuuchhhh. What where the conditions? Mapping?

[Ruffiano]

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!

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!

[QUOTE=andy10v;599045] 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?[/QUO

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.

[andy10v]

Thank you for the ideas gents

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

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?
