Carbon buildup
 

Is it a problem on our combination DI/PI cars as it is on DI alone? Should I run a fuel additive periodically? Is a catch can worth adding? I use only Mobil gas because the Ferrari Club rates it among the cleanest burning.

No
No
Not really unless really pushing the engine.
Not a Ferrari.

Yep, Like @Tcoat says, the port injection part of the fuel delivery system pretty takes care of most carbon in the system.

Fuel additives in modern engines benefit the owner more than the engine.

Catch cans are more for mod freaks than the engine (for most not tracked cars).

I understand Mobile gas is good gas.

Circkle K, Exxon, Shell, Mobile, Cost Co, and many others are "Top Tier" rated gasolines which all have the same MINIMUM rated additive and treatment package required to be called Top Tier. EPA said it has to be X, fuel companies have been adding in more than enough since 1995, banded together and made it a marketing tactic.

Here is a link with a complete list.

"All retail locations within the US (including US Territories) and Canada which carry the licensed TOP TIER™ Detergent Gasoline brands "

TL;DR Ferrari Club members drink the coolaid.

No, I actually have some pics of the intake manifold off if you'd like to see them.

I had a 308 and a 328. Don't have time now but can send pics later. I wish I had them both back.

Could well be. My thanks to everyone on this. I do plan to track the car a few days a year and will add an oil cooler.

I like to see let's get the party started :party0030:

Still saving for my 355 :sigh:

The catch can is less for the fuel injectors and more for the top of the piston, preventing carbon buildup and excess water being burned in the combustion chamber....

Here ya go. Not the best quality, but it'll give you a rough idea.

Jesus I have edit my post now to Ferrari’s
What the hell you doing with these cars? Lol

Looks like he traded them for a Miata - :w00t:

Just set up dropbox. Let's see if this works. 328 on Blue Ridge Parkway. Can't find any of the 308 at the moment. Probably on an old storage disc. Sold it more than 10 years ago.
