Max HP on stock internals

[Fashraf]

Hi Guys,

New here, was just wondering what the max HP the Raptor engine can handle before getting into the engine internals ... Pistons, rods, crank etc

Thx

I think about 500 rwhp is maxed. Thats just from reading threads...

Yeah I would say 500-525 rwhp is where u are still safe and reliable. After that its starting to push it.

Ive been running about 500RWHP for 17K miles now no issues at all. Just to be safe I ordered the Billet Oil Gears from TSS, JT Air/Oil separator and the BoostAPump is next along with a wide band Air/Fuel meter. Just depends how are you drive her too.
I let the power come on and try not to let it drop 2 gears bang then upshift. I would imagine your asking for problems if your trashing on it.

Taking 30% for wheels and parasitic drive train loss that's about 650 BHP

Are those extra parts necessary for someone running 500rwhp?

I would think it would be under 20% drive train loss but not sure if anyone has run a motor on a dyno and then run the chassis, but would love to know that.

I think a big part of this is the tune. When I installed the supercharger I asked Livernois to be conservative on the tune as I did not want it to run lean. Most likely the pistons would be the first weak link as they are cast hypereutectic aluminum. RPM's have not been an issue with mine even turning 6200. So with all of that being said I would not go over 600 at the flywheel even though you most likely could get a little more out of it.

I would agree 30% might be a little high but 25% is a good approximation. Most stock trucks dyno between 310-320 rwhp (mine was 312rwhp stock) and considering that Ford rates these trucks at 411hp I would say the 25% mark is close.

You probably don't need all the extras but Im running a slightly smaller pulley bc we saw a drop from 9lbs to 7lbs when we added the headers and exhaust. The smaller pulley brought the boost back up and added a few more ponies. Due to the extra power on the stock internals I elected to buy the above mentioned extras.

I'm adding headers too so i might run a smaller pulley as well

Im glad I added mine, I get more compliments on the sound of my truck than anything. I went with SW Headers to High Flow cats and Lightning (Street Queen lol) exhaust exit. I joke about the street queen part but I did have the weld it in a few extra spots to make it a bit sturdier.

With the Stock pulley and Headers/Exhaust I lost 10HP and picked up 30 RWTQ so the smaller pulley brought the HP back up and we keept almost all the added torque.
I would recommend it for sure. This is also where having it tuned on the dyno helps.

I'm looking to do the same exhaust setup. I do like the quality of the ARH headers over the SW however
