2011 Raptor Whipple Supercharger

[sisaacks]

Hello All....I have had this truck a year, it only has 20K miles on it and its been a nightmare. I did have a procharger installed. That was removed and a Whipple was installed. I thought everything was great, then it started missing when underload at high RPM's. The mechanic has broken two pistons testing it and trying to figure out what is going on. The tune is from JDM. The mechanic is suppose to put in new pistons and put it back together and get some data logs to send JDM.

All I know so far is the truck is pulling timing because of some audible noise the knock sensors are hearing. JDM said I should replace the block, the mechanic is saying the block is fine. I am going on 4 months now of the truck being in the shop.

Just curious if anyone out there may have had a similar issue or maybe some insight. I am to the point I am about to just sell the truck at a loss.

The only suggestion I have is to listen to JDM and maybe get a new mechanic. Can't you pick up a used motor cheaper than all of this foolery and install your whipple on the new motor.

That Procharger probably already compromised the engine, especially if it had the Hennessey Tune!!!!

If it were me, I would start with a new Ford remanufacture long block and get upgraded oil pump gears.
That's what I had to do when my stock oil pump gears failed within a year of being supercharged.
I only had 7,000 miles at the time, about 2,000 being supercharged.
And now I'm going strong for 8 1/2 years

Brother, 4 months in the shop? Hell with that.

Were it me, I would shitcan the current engine and replace with a fresh 6.2L. Who knows what damage has been sustained previously and you’ll be chasing engine issues forever.

Get a price from your local dealer to save shipping. Do oil pump gears before you reassemble it. You will be good to go.

I would have the mech send your injectors out to be flowed and serviced, make sure you don't have fueling problems.

Once your back together take it to a dyno, have them make a run and verify the tune is safe, something is up. It is easy to blame the procharger setup, but assume that the engine was good when you had the whipple installed, and that this engine could let go just as easily if things aren't resolved.

Make sure the blower gets inspected prior to reinstall. Check for play, make sure nothing went through the rotors.

What two cylinders let go? Do you have any photos of the damage?

If the pistons are damaged, you most likely have damage to the cylinder walls as well. Both Livernois and MMR sell forged 6.2 short blocks, which is the way to go if you're running F/I. The factory pistons and rods were never designed for boost.

Replacing the oil pump gears and crank gear with billet units is mandatory BEFORE boosting any Ford V8. Do this right away if you haven't already. Your mechanic or SC vendor should have told you this. Two dead pistons is likely detonation from bad fuel, lack of fuel, or ****** tune.

I would: 1) drain the fuel and refill with fresh 93 octane, 2) replace the injectors with ID1050X units, 3) check for proper fuel pressure 4) call Tuned by Oz for a custom tune...I swear by Ken. So does my 900hp Whipple Coyote.

Also could be cam timing if the oil pump gears have already been replaced. Maybe off a tooth.

You probably don't need a new engine. Unless the block is cracked, you can pull it and bore it .030 or so over, and do a short block rebuild with forged bits. Not sure if just replacing two pistons will do it. Maybe, if there is no cylinder wall scarring. Ask for good pics of the cylinder bores. The mechanic should at least hone the cylinder walls and properly gap the rings.

I'm just going to say this one time,
A Ford Reman LONG BLOCK!!! and get the upgraded oil pump gears is all you're going to need.
The heads will be completely rebuilt with all new main, cam bolts and head studs and cam phasers and chains and guides and it will all be torqued properly.
It comes with a Ford 180 day warranty, it ain't much but at least it's something.
This is the cheapest and most reliable route!!!

10's of thousands of Whippled and Roush Raptors are running stock engines for years without issues!!!
But most have done two things, TRACTION BARS and/or oil pump gears.
JDM will tell you that with their Tune you don't really need to do the upgraded oil pump gears.
Doesn't mean they don't recommend doing the oil pump gears but they claim that 100's run their Tune without doing gears.
But they also make you run the smaller 47 lbs. injectors and the smaller Twin 65 mm TB
Their email Tune is very conservative with smooth shifting.
They do other Tunes for the Raptor but you would have to take your truck to them.

Anything more than 60 lbs. injectors is a waste of money, the stock fuel pump does not supply enough fuel for anything larger,
Unless you do a boost a pump or upgrade the fuel pump. Plus the stock engine won't use more.

If you're looking for more power than 720-750 HP at the crank, then it's going to cost a hell of a lot more to be reliable.

Agreed, over the years the 6.2 has not liked being procharged, but Supercharged engines appear to be very reliable, just stay away from Hennessey regardless.
