Also note that Lucky went out of business.

So take his advice with a grain of salt.

And get a boost gauge.

swedespeed may have more Volvo moders.

Yup, ita cheaper to get a boost gauge, oil pressure gauge and a afr gauge, than it is to rebuild the engine xD

19T, but otherwise the overall goal is the same: https://www.matthewsvolvosite.com/how-t ... -v70-fast/

This guy is a mad scientist xD wonder if he calculated the airflows to be preferable with the bigger maf etc.

Update:
I was lucky enough to get my hands on a 16t for less than half the price!
I also bought blue injectors. Wooo, time to make (some) power!

I'm in the process of doing this, but it's not going well because I have somehow built a super16T that flows as much as a 20T

Overflowed the MAF, bent some rods, overflowed the injectors, started knocking again

oh no!

So. When making rockets, it helps to be a rocket scientist?

The bent rods might be indicating too much boost too low at the rev range. I remember something like it needs to be ~0.7 bars under 3k rpm. Take this with a grain of salt tho, its a "trust me bro" statement

the bent rods were from me not looking at the data, doing a pull for logs, ran out of MAF unexpectedly so it was running super lean

The second time it started knocking makes no sense, there isnt anything wrong in the datalog

I'm replacing the knock sensors and installing an oil pressure gauge this time (+ some H beam rods and new bearings)
