Anyone Adding A SC, Turbo Or Keeping It NA?

[65Terdlingua]

The main concern for the engine itself is detonation, which can be solved with high enough octane fuel, a safe tune, retarded timing, etc. It's just like any other boosted application.

The rods take the highest load under tension at TDC on the exhaust stroke. The engine will tolerate some amount of boost as far as the rods are concerned.

I sure wouldn't add boost - I'm a total chicken and won't want to damage my expensive vehicle or even to void the warranty, but there's no reason the engine cannot be boosted.

I'd say the main concern is the rings and ring lands. Look back at what I said earlier about them under too high of pressure. Blow by, ring damage, or piston damage caused by boost pressure on an already very small ring package

Do you really think the ring seal tolerances on a production motor are going to be so tight, or maybe in this case so loose (to take advantage of the the things you mentioned earlier) that it won't seal properly on the combustion stroke?

I have no plans to add FI. 526 should be adequate power. If Ford provides a tune, great. I like having a warranty. The mod that comes to mind is a nice harness for the track. The other thing is a spare set of rims and snow tires. I don't plan to specifically drive it in the snow, but I've read that the stock tires are not meant for temps below 45 deg. and I will be driving it below 45 enough that snows are a worthwhile investment.

I'm no expert with engines, but seeing the pistons and rods in pictures they look small and purpose designed. And not designed for boost. They are light looking, not beefy at all, so sure go ahead and boost an engine not designed for it. Unless you go extreme low boost, on a stock motor, I think the only outcome is a damaged engine fairly quickly. I really don't think compression is the issue here, it's the internal component's being designed for high rpms in a large FPC engine that's more of the issue.

I personally don't have a lot of faith in the engine in terms of longevity as it is. I hope i'm wrong, because if I am I'll probably trade in my GT for a used one later down the road. It's a great car, but there are too many causes for worry with this engine. from reading about having development issues keeping it from tearing itself apart, and reducing power to a level that the engine can be at least acceptably reliable to Ford. (Ford warranties really aren't that long) Last but not least, the recently recinded Ford handbook talking about the builtin "overrev" safety feature. It just doesn't scream reliable to me, I want an engine that will last at least 150k, but more so almost 200k without serious engine issues. I'd be surprised if any of these initial GT350's come remotely close to 100k.

Could happen, especially at higher levels of boost. My point is at least some amount of boost is possible. Some fuels especially alcohol based fuels have significant cooling effects that reduce the chance of damage.

Really. Are you considering buying one? I assume not.

I admit to having some concerns about longevity, but I'll be surprised if most Voodoos don't last past 150k (if they are being driven regularly by their owners). I could see many not making it to 100k because they sit under car covers, but not due to engine problems.

That would be a no due to my concerns, if I didn't have any... I would be very much considering buying one instead of modding my car.

Obviously not for a production vehicle in stock trim or even slightly modified. And it's not about their tolerances being loose or tight, it's about high boost pressure putting excessive stress on the parts and causing failure over time. Could they handle a FEW pounds of boost and be alright? Probably for a while. But once the pressure goes any higher there will be more force excerted on these rings than they were designed to handle. Keep in mind they are designed for minimal drag with RPM being a priority. Not like a Coyote ring set that has more standard sizing that is capable of withstanding that sort of abuse. And the pistons are also very small to allow for high RPM so there isn't a ton of material under the rings which could be prone to damage with high boost and a lot of stress from that. I'm just saying of all the components, this area is probably the weakest link.

^ fair enough. What we know is someone will likely do it sooner than later and then we will have test bed from which to go on.

Exactly. Hopefully they are careful and it lasts a while. When someone gets crazy and cranks it up, bye bye Voodoo.

For me, I'll keep it NA with only a few bolt-on mods. I plan on buying and enjoying my GT350. I've built enough Mustangs in my life that ended up spending more time being rebuilt in an endless quest to achieve more HP than actually being driven and enjoyed.

Equal length headers, straight exhaust, tune, recaros, track pack spoiler, call it a day.
