My understanding is they turn the redline down for every single car they tune for reliability sake. Is that true @Trevor@FatFab ?

I got a solution (I’m sure ppl will be mad) replace it with a coyote. Similar hp, handles more boost, no piston slap. I love the way it sounds and is a great engine but I keep hearing a lot of ppl have issues with it. I own a boosted gen 3 coyote and I have had 0 issues with it since I got it 2 years ago. Plus there’s not a big hp difference when stock. I know it’s bs but watch the am video of replacing your cai and how it gets you the same hp as a stock voodoo.

You mean the Mach 1?
In all seriousness, the FPC engine in the gt350 serves a very specific purpose. Less rotating mass in the crank means faster revs, which is very important on track. Also, 550 extra rpm over the gen 3 coyote means you can stay in each gear slightly longer on track. For me, that last part was huge as the two fastest points at my home track I was right at 8,200 rpm. With a coyote I’d either have to shift before my big brake zones, or more likely just bounce off the rev limiter for a second, sacrificing speed. I know that sounds insignificant, but when I’m fighting for 10’ths or 100’s of a second on track trying to beat a personal best, I’ll take any advantage I can get.

The shining glory for me of this car is that sweet sweet exhaust note. I'm not a track rat so this may be an option for others - but for a dude who streets the car - I bought this car for the Voodoo.
I contemplated getting a shiny and new Mach 1. Similar with tremec and mag ride, also reliable Coyote. They sound great too...but man the 350 is special.

Your comment has left me aghast and made me accidentally shatter my monocle. I shall have to ask Jeeves to run down to the shoppes in the autogryo and procure me a new one. Now my afternoon tea is ruined.

if your concerned about the rpm’s you could just replace your intake manifold to the gt350, boss or ford performance. All of those would give the coyote a similar if not higher rev limit. But i was reading and bringing the voodoo rpm’s higher is what is causing all the failures. Plus the coyote is better for boost, the snack packs have a similar boost issue. That’s why the hell cat has a different engine.You mean the Mach 1?

Not a bit. The engine is flawless. I think much of this criticism of the 5.2 is a bit overblown. We see people posting about engine problems on this forum which have validity; however, I think the majority of GT350s are rolling along just fine and there are tons of GT350 owners that do not participate on these forums and are never taken into consideration.

Not saying I am having a problem with my Gen 2 replacement. But when I hear varied stories on piston slap I scratch my head. Why some have it, why some don't???

Zero Issues and I rev mine all the time, Been told lugging the engine is not good for it. Go ahead and add the slap an intake on a Coyote and rev it to 8250, Just have another engine handy.

^^ Another one trolling the 350 group and has zero understanding of what the 350 is all about. "I can make more power with a cai" is very adolescent and pretty much explains it all. Oh, and the coyote doesn't have piston slap? lol - of course it does..and BBQ tick.

Ugh, will these posts ever go away? I have piston slap. Noticeable around 2300 RPM when cold. Get a warranty, let the car warm up to 180, check oil every now and then, and send the mamma jamma!!!
Did my research pre-purchase...it SEEMS the Gen 1 has more failures but there are still plenty of failures gen 2.

A friend of mine who runs a ford service department in Indy that has a working relationship with fathouse told me about it. After I pinged fathouse yesterday, I can see from their history that they read the thread but chose not to respond. Since they won’t confirm or deny, I suppose it’d be easy enough to ask any of the fathouse tuned guys on forum where they tach out at.
Maybe fathouse doesn’t want to give away the ”secret” to their reliability success….. orrrrr my guy at Ford who knows them and Johnson tuning well was just making it all up
