Through some strange circumstances I once had the misfortune to try to diagnose some +T mess on a hooped out b230f that's only saving grace was that it replaced a b230ft that apparently had a rod through the side of it prior in (what was originally) a stock 7/9 turbo car otherwise.
That thing pinged all over the place. The car being totally worthless and owner not really able to pay for anything, nothing ever went anywhere after the test drive (me in the passenger seat...wouldn't even touch that thing or drive it) listening to it on moderate acceleration ~0 vacuum even go "click- CLICK-
CLICK" ever louder. before it even remotely hand the chance of reaching any significant boost. Me "so how long has it had this symptom (intermittently low on power on warm days (probably knock sensor/ECU thinking the world is ending at best)
)?" Them: "About 6 months." (car lands in PNP a few short months later).
In another instance I encountered this same fine bit of work on a really clean 945turbo.
Replaced the hooped out b230F+T hack install with a really low mile b230Ft and rebuilt the injectors and a few other things, no more deathly rattling/pinging.
How do people imagine that more boost/faster spoolup on lh-jet is going to work out on a worn out ~10:1 static compression engine?
Remove all safety margin and make sure all sub-systems and state of tune is worse than just a stock stage 0 car is a proven winning formula.
Pfffft. Amsoil. It's all about the Motul 300V baby.
But seriously, the amsoil synthetic 2t oil is great.
Oil that's $12-$15 per little pint vial or whatever on a tb budget
INB4 "The oil change / Fill up is more than I paid for my car!"
In all seriousness, the Wankel endurance guys (with vastly fatter wallets and not caring much about fuel consumption or tailpipe emissions) swear by either/both those products.
I can see it now:
Hold your engines together with Seafoam, Motul/Amsoil/Joe Gibbs 2-stroke racing oil, jet fuel and prayer.
The fact that you can even get 10psi in 100?F degree heat with that thing is a miracle. With all the chips, hackery and tweaking with 91-94 octane less emissions friendly gas than CA and to some extent OR piss gas I can see.
The owners of said above cars were just using CA/OR ~87 octane/certainly nothing special, which a stock B230F in about as perfect low mile repair as possible will ping (lightly) on some transitions running at heavy load with the A/C on in 100?F heat, to be fair.
This is TB anymore though
:
....try really hard to win the special olympics with a hack job +T on a hooped out motor that's almost as fast and vastly less reliable and requires more than 87-91 octane/nothing special pump gas than a basically bone stock near new turbo car, and probably slower than a no-cat model with the original Volvo turbo+ setup that ran ~12+psi only at heavy load and modified the timing curve slightly on later versions
