So,...for those of you that have a supercharged/turbocharged '10-'14 Coyote car, did you do the oil pump gears and camshaft sprocket gear as well? The reason I ask is these seem to be the weak links in our cars, besides the rods I do believe.
If you did not upgrade these items, why not? Just curious and want to see what others who are supercharged/turbocharged say about this.
Thanks!

 

I did not upgrade anything on the engine, my reasoning being I was only running 7.5 PSI of boost and was keeping the factory rev limit.

 

Negative on my end too.

I think most "kits" out there - which is what we mostly have - come with everything you need to "reasonably" up your power from stock. I don't believe any of them come with (nor do they recommend) changing those gears. I think if you up the whp to 650 or more, perhaps that's a concern, but I don't know.

So yes, stock internals for me for now - and I'm good with where I'm at for power levels.

 

Thank you guys!
I appreciate your input.

 

I'm not boosted...yet...But from what I have seen you're pretty safe untill 600+whp

 

That's just it, 600-650 HP at the rear wheels is what I'm concerned about. 600 at the wheels would make me think about it.

 

Now you have me thinking about it. lol

Kidding - I already have thought about it, and I think I'm ok.

 

This is the reason I ask,......This was posted yesterday way after I had started this thread.

He was spinning to 7K, so he had upped the rev limiter. I talked to my tuner about this and he said most, if not all of the failures he had seen were due to upped rev limits and/or aftermarket harmonic balancers.

 

****, I was planning to get the whipple on my 16 and someone mentioned OPG and I said no way I'm doing that. I have a 13 with a broken piston now and it's back together with a new piston so I know what goes into getting these things apart. I may think twice about it now. I'm also having trouble correlating high hp to opg failure, I can see high boost and high rpms, but I just don't get the high hp argument.

 

What's our current rev limit, 6800? Mines the same as before if not lower, I believe.

 

This is VERY true sir. I have read about that very statement. I guess I'm just being "overly cautious". lol
No way do I spin my tach anywhere near the redline anyways.

 

6800 sounds right. But, if he says 7K, he may have the limit set higher had rev to his new redline at times. Not worth the risk to me to chase a dyno number.

 

Very true sir.

 

This is my second boosted stang, first was 13 and now my 14 and I never upgraded. Been WOT too many times to count along with several drag strip outings. The main reason they break is from bouncing of the rev limiter or missing a gear. Its more of a shock to the gears rather then the HP.

 

Thank you for the replies and information guys!
Great read here.

 

If you're doing the work and spending the $$ on FI, why not spend the few hundred more for the billet OPGs? Seems like it would be worth it just for the peace of mind. I know it's a PITA to do, and more work, but you've done 2/3 of the work by taking the chains off already anyway.

 

This is what I'm thinking. I would probably do bullit when the time comes. Just for peace of mind.
But, like most have said here, only people that spin their car way up the rev limits are having troubles with the OPG's and sprocket gears.

 

Be selective when picking out the blower kit also. A bigger blower can always be toned down with pulley sizes. The bigger cc blower will allow more scfm with less boost pressure. So you can actually add more hp with less boost. My cobra was at 21psi which could have done the same power at 15 psi with a bigger blower. Lower psi and more scfm will help with longevity. Lots of people producing big power with these cars and have never cracked a valve cover off. Wouldn't worry about oil pump gears honestly. If you turbo on the other hand, good luck with any and everything.

 

Why did I take the chains off already?
