Beautiful red dark horse lost the engine

Nah, 800-900rwhp not enough power on it's own to sling a rod or crack a stock piston. They can hold ~1300rwhp full send reliably

Nah, 800-900rwhp not enough power on it's own to sling a rod or crack a stock piston. They can hold ~1300rwhp full send reliably for quite some time before going. If the tune is sound and the fuel is good, at best a Stage 2 with full bolt-ons is making ~70% of that. Should last for several years before needing a rebuild. It's kinda what the platform is famous for all these years.

If it's not the tune or bad fuel that killed his engine, it's far more likely he didn't replace his oil pump gears and timing sprocket, as those are the only weakpoints in the engine when going from stage 1 to stage 2. And they WILL make themselves known if you drag race, typically shattering coming out of the hole where the shock is greatest and then starving the engine of oil down the track.

Well you confirmed exactly why I'm not supercharging.

"They hold up fine for some time before going".

Without a supercharger they hold up even more before going. That's exactly why I commented.

I agree. I was also considering SC installation as my previous cars were with turbos. It was tempting. However I did my self good research and found out even with regular and care driving style the SC put extra pressure on the engine on regular basis regardless of drive style. At its core it does shorten the lifetime of your engine no matter what. That is the reason I pass.

Agree. Cars that already come with a Turbo are cars that are made to have a turbo. If you want to supercharge your NA car you need to change a lot of expensive parts to make it handle the power. Many people want a supercharger but don't invest in making the car handle the power. That's when it goes bad.

If you want the power, invest in other parts to make it handle the power.

Depends on the car. The EcoBoost Mustang doesn't like having much more than 100-150hp added to it on the stock engine. That's not much (percentage wise, 30-50%) compared to what you can add to say, a Coyote.

You really don't need to change anything. Sure, for traction you'll probably want to add better tires, a couple suspension parts, but that is all stuff that people add anyway.

If you have a good tune, use good gas, keep an eye on things, maintain the car well, your car will run for a long time with 10psi of boost (650-700hp)

These engines are tough. They will generally hold 800-900hp for quite a while.

Your oil pump gears are not going to magically explode. Your pistons or rods aren't going to blow through the side of the block. Your timing chains won't magically break.

Now, that being said, do you want to blow it up or break shit?

Run crappy gas from the grocery store or discount gas stations. Run the car hot. Don't watch your knock sensors. Don't watch your intake temps. Don't change your oil very often. Race it with 1/4 tank or less of gas in it. Buy cheap parts. Ask your tuner to PUSH IT TO THE EDGE. Drag race the car every weekend. Hot-lap it. Make 4-5 highway pulls in a row. Get a burble tune or sit and bounce the car off the limiter. Launch it on slicks with stock axles.

If you're going to race the car I would be worried about the following, in the following order:

Stock catalytic converters
Driver side axle (if you're going to run sticky tires)
Stock 10R80
Stock pistons

And if you're at 700hp or less I wouldn't even worry that much about the last two.

Of course, parts can fail, and losing an injector (for example) on a supercharged car can end up a lot worse than losing an injector on an NA car. But in general, your car should run for quite a while even boosted.

Supercharging IS a risk and there's a big difference between making 650hp and 900hp.

Ofcourse, 650 is not the same as 900. That's why I keep it at 486. Because 486 is not the same as 650.

Ford seems to think 810hp is okay, they warranty it after all.

Yup, but I keep cars much longer than the warranty.

Cat(s) probably failed and clogged up the exhaust and forced that cylinder pressure back into the head and broke the ringland on one or more of the pistons. Thats pretty much the only reason I could think of that a whipple tuned s650 would pop. They are ultra conservative with their tuning. Their WOT fueling is like .75 lambda and they leave cat over temp enabled which will enrich further to .70. Thats pig rich even for a blower coyote.

I'm speaking specifically Stage 2 and beyond. If you go Stage 1 Whipple with a Whipple canned tune, your car will probably live just as long as it would NA. They detune it to 800bhp, walk the red line back, and install a super soft rev limiter that honestly sounds weird AF if you stand on the gas in neutral. It's made to live.

Again, you're not wrong for being hesitant. Forced induction absolutely requires you to keep an ear to the ground, so to say. Very little when you're Stage 1, but if you go Stage 2 you should pay closer attention to things that most serial drag racers do anyway.

That said, most of the issues you're concerned with when using a blower are the same issues that can kill an NA engine. Bad fuel, going too rich, going too lean under load (injectors, wideband O2 sensors, or fuel pump malfunctioning), standing on the rev limiter, shifting in the red repeatedly, living at the drag strip, staying at high RPMs on an autocross track, the oil pump gears shattering due to a hard launch on a prepped surface, etc. You just have to be more vigilant when you supercharge it, but it's really not a big deal once you get used to it.

This is the other point I forgot to mention. If you run supercharged, get rid of the cats! I don't have any because they can absolutely superheat, start coming apart, and small particles get pulled back into the engine to kill it. It's common enough that the dealership AND Whipple both warned me about it. I'm sure there's probably some aftermarket cats you can go with, but I'd rather just roll without. I've never owned a toy that had cats so I'm not super informed on which ones would be safe to use in this scenario.

Yeah removing the cats is just about mandatory with boost. Just get the headers and move on with your life...lol

You guys are allowed to delete cats in the US? Here you car documents will be suspended during the yearly check.

 

[d4rkg04t]

Plus, on top of it, if you just drive it like a sane human being it will last forever whether it's supercharged or not. Beating on a car is what kills it. And, if it's any consolation, I'd like to reiterate of the 30k+ miles I have on mine, most of them are merciless full sends at lights and on the interstate. If the engine or tranny starts to go, that's fine, I'll have them rebuilt. It costs money to play.

It is in the American spirit to refuse to obey, after all.
