I had a problem with the cowling so I switched over to working on the canopy. Always plenty of work left.

This is the current state of the airplane. I have now caught up the VAF postings with the airplane. This project has been an awesome experience. I see another build in my future.

This is my current issue I am working through. I bought the titan engine new from the manufacturer. Before I bought the motor I placed a call to Vetterman for one of his exhaust systems, He mentioned that I need to only use the Superior cold air sump with his exhaust. I let the salesman at titan know that tidbit. Unfortunately, with the cowling on I do not have enough room for the throttle servo to mount the induction snorkel, let alone have the approriate clearance with the cowl. It has a little less than 1/4". (See attached photo)

The sump is a superior cold air sump and the throttle servo is a Silverhawk.
I have no experience with either. Unfortunately Titan doesn't make their injection system anymore, that would have been the best option as it was 2 inches shorter. I think I bought the engine right as they stopped making their injection system. The motor was purchased before continental motors bought them.

My question for this forum is which option is best or are there other options that won't cost me power and/or screw up the cowl lines?

A) I go to a 7 degree Titan sump. This means that I can't use the Vetterman exhaust. I will probably have to use the titan exhaust. Will I loose power? The motor dyno'd out at 204hp. The more power the better in my opinion. This means no cowl modification. Depending on what Titan does this could add on a significant cost to the airplane.

B) Modify the cowl with a pimple/blister to accommodate the longer throttle servo and try and fill it as best as possible. The blister will be around 3/4" out on the cowl and would screw up a **** good build and airplane in my opinion.

Thanks for sharing, looks like you're making great progress.

Your issue is beyond my technical knowledge base so I'll simply say congrats on your progress so far and I'm sure someone will chime in soon enough here with a suggestion.

Machine a wedge to go under the flange between the the servo and the cold air induction. It would need to be something like 1/4" to zero on the top. Might work. Does Airflow make a shorter servo?

I'm using the eci 7 degree sump on my RV-8 and the Vetterman 4 pipe exhaust and it all fits. Did you speak to Clint about the 4-pipe?

I am using a different throttle body though so clearances with the cowling would be different.

Default Bracket

Hard to tell from the image and much of the detail is covered in tape, but can you file off the end of the bracket to gain additional clearance?
