19T + e85 too much for stock bottom?

Why are you using such high viscosity oil?

50 weight is recommended by many, including Ray, specifically valvoline 2050 VR1 racing oil

Valvoline VR1 20w-50? Valvoline advertises that oil as "Not Street Legal" for a reason. Unless you're revving to the moon and cavitating your oil there's no need for an oil package like that on a street car. There's 0 startup protection and so much zinc and phosphorous in it you'll burn up your cat...

yeah I'm going to argue with my engine builder about what oil I should run, sure. You can do that with your own motor.

this is what I'm going to run for breakin:

Here is what I'll run after 500 miles or so:

Ray recommended the same VR1 20w50 to me. (As well as another member). They have 10w30 as well. It's also nice that they offer the same in both reg for break in and synth, as you have discovered.

No cats for me

I got 4 cats, but none of them on a Stealth.

High zinc oils are recommended by turbo manufacturers.

Zero startup protection??

You do realize excessive amounts of sulfur, phosphorous, ZDP, and so forth accelerate engine wear once they've reached the cumulative limit and they only afford protection in certain temperature windows? The reason why this particular oil is advertised "for racing use only" is because one using this blend of oil should expect their engine to be broken down more frequently due to the chemical impacts of the oil package and the metals in the rotating assembly. The protective package for this oil is for high heat. At a lower temperature it affords little to no protection. Valvoline specifies use in race applications which involve frequent engine disassembly for that reason. Unless you're driving around at wot all the time and plan on pulling your oil pan every 30K I wouldn't use it.

Valvoline VR20w-50 is because racecar oil.

For another thread...

Did you not look at the links I sent? They are not the "offroad only" oils. That is a separate animal.

"
Valvoline VR-1 racing motor oils are recommended for engines burring gasoline and full or partial alcohol fuels in track and street service
Use in any car, light truck, van or SUV where API SN is recommended
ZDDP additive provides tough anti-wear protection
Enhanced with friction modifier to improve horsepower
Formulated with enhanced anti-foam system

I read the amazon advertisement you linked in. You should read the one from the manufacture, I posted it. At 35 degrees F ambient the viscosity of VR-1 20w-50 is over 1200cSt, which is equivalent to sucking jello thru a straw. At 70 degrees it's basically lifts as easily as trying to sip a milkshake with a coffee stirrer. I have two final words regarding that... Kinematic Viscosity. That oil offers nothing for protection until it reaches an operating temperature of 120+ degrees. It's for setups where you very rarely turn your engine off and where weather is always warm.
