Car has never went better

If the reg is before the rails that needs to be fixed

I'm running 15-16 psi and a 50 shot, 915rwhp on straight 93 and 19 degrees

Someone didn't know how to set the valves???
Those valves could well have been torched w/ hi egt/not on the seats/little to no heat transfer.
Note they are all 4 burned at about the same place. Where the flame kernal starts @ the plug tip. The "cutting torch" egt at probably 2K *, [or close to it], had a relatively easy time of melting those edges off the valve, and the plugs.
I would also ask what the valve material is.
Did the racer read the plugs when the car was first raced/leaned on??

Nicely stated.

The fact that a whole bank went lean points to the fuel set up in my opinion.
And also go more conservative on the tune.

who made the injectors and were they used?
just making sure they arent smart fires ect...


some more photos would be great when you get the chance. first off, sorry it happened to you man. Second, I cant believe you only made that many passes? I would have 3-4 on the way home from the dyno.

That kind of timing would warrant some VP M1 100% or E85 IMO.


Werent you running a 2 step? Seems like I recall the car hitting the limiter on the 9.95 run.

Well as for fuel system the shop picked it out and installed it all,
Injectors were supposed to be brand new and I think fic 100lbs.
These are all the pictures I have ATM since engine has been shipped back to builder
Who is telling me its either a fuel or tune issue this all happened back in December been horrible experience to say the least.
As for the shop they said they'll work with me on the labor as in taking engine back out and reinstalling it but have not been told any kind of numbers yet.
They were a sponsor on here but are not anymore.

Well I thought the shop could handle this build and had tons of good feed back,
And assured me the car barely needed the meth when they dyno'd the car, that pass I touched the limiter because was the first pass with new shifter it was the only time it happened.

This shop wouldn't be out of Kentucky by chance, would it?

That's really weird. I don't think the tune or setup was out of line, specifically amount of timing or fueling or the amount of boost.

I am really interested in hearing what happened. The positive side, if there's one, is at least they were a factory head, and it looks like the damage is just in the head, so the expense shouldn't be too bad. Like everyone else said, I'd look towards fueling first.

Ok I wasn't going to say anything about Lashway since I still thought they were a sponor. IMO when I called, I never got eric or josh....hardly ever. Think they were based out of florida.

Brandon, you will probably have to do the same thing I am going to do and take the car out of state to get a good tune. Call up Vengeance Racing or RPM Frost, or James Short Justune, anyone but the new guys that are not going to be around very long. Two things you cant skimp on. Fuel/Tune.

How true. Way to see the silver lining in all this. It could definitely have been much much worse. Hopefully none of the pistons got damaged.

He said in his first post he has to replace 3-4 pistons.

Why is the corner of the threads burned away where the spark plug threads in? Two possible things. . I think everyone knows this answer.

Regulator needs to be fed by both rails and return fuel after the rails have been fed. Too much timing for my taste and too hot of a plug as well.

Would love to see what the pistons look like. Melted? or chipped/scratched?

Yeah Brian at Aes didn't send pics of pistons but most damage was done to 1 head and the valves waiting to hear back from him if anything else was wrong. Ill update once I hear back from him just been so aggrevated with all that has happened with car and its not been just the engine damage either.
