Engine turnaround

I don't see it on Van's site. Is anyone aware of the anticipated turnaround time from order to delivery for the IO540 conventional vs Thunderbolt engine?

I ordered my experimental 540 August 2024 and received it last week, 6/19/26.

18 months standard version, 14 months for Thunderbolt. Having said that, I've been waiting for 38 months for my Thunderbolt.

Any speculation on the difference between website quotes and actual delivery times? Also, any idea if one or the other is more prompt (conventional mags, Lycoming EIS, or dual P-mags)?
