Didn't bother me - I'm still waiting on my Titan engine that I ordered 14 months ago - but just FYI that the quoted lead time might be optimistic.

Very true, I didn’t really buy-in to a 2 week lead time. I was already six months with Vans and they finally pulled through.

Previously I wrote...

As delivered the, servo mounting flange on the standard horizontal plenum sump has a diameter sized for an RSA-5 servo. The much larger FM200 will bolt on with an adapter, but the small sump inlet is still there, choking the flow.

Picture worth 1000 words...during a recent inspection I shot this photo down the throat of the FM-200. The gold constriction at the rear is the adapter, reducing the FM-200's diameter to the sump plenum inlet diameter.

The FM-150 was not available back in 2007, thus the 200 on an adapter.

Much of the of throttle plate angle change near WOT does nothing significant.

The biggest difference between the older is-390’s and the 119 version is the sump and intake tubes. The IO-360/200hp exhaust will fit on the older model 390.
We’ve built several now for the 119 engine on rv-8’s, and they are a crossover. There isn’t enough room in the rv-8 cowl to do the trombone system.

We are trying to deliver systems in 2 months. Sometimes we’re long, sometimes we’re short. We are trying though.

Thanks Clint, I am a little confused, will the stock Van's RV8 cowl fit on the 119 exhaust from Van's?

Thanks in advance
