How safe is it being supercharged?

[stannypack]

thanks all, will be a while before I get a whipple but slowly learning about all this stuff

23’ GT with roush stage 2 for the last 5k miles. I know it’s early to say this but it has ran flawlessly on the factory tune. I drive spirited but never track it and most pulls are freeway on-ramps and last less than 5 seconds and usually don’t exceed 6000 rpm. I figure if something goes to Shit at some point I’ll swap out to an aluminator with a 9.5 compression ratio and build again. Think of it as a hobby instead of a risk and enjoy it. No car lasts forever.

2016 gt vert with Roush supercharger, 75mm pulley, ID 1050s, long tubes, vmp twin throttle body, big vmp heat exchanger, jlt intake, tuned by Palm Beach Dyno made 767 to the rear wheels on 93. I purchased the car in March 2020 with 13k miles and am at 132k now. Car has been dead nuts reliable with the exception of the AC condenser which has been replaced twice under warranty and the heat exchanger pump which went out at 90k miles…

wow. That’s awesome to hear. Did you use a performance shop, dealer or do the upgrades yourself?

I actually bought the car fully modded from a dealer outside of Tampa. They had it advertised as a Roush car and I knew the difference. It was highly modded with few records and after I educated them on the fact that it was not a Roush Vin car and that due to the lack of records they would have a difficult time selling, I purchased for the price of a used stock car in similar shape.

the previous owner had the mods done in South Florida and traded the car in on a Corvette ZR1

1. Coyotes eat boost
2. If your concerned about reliability, I would abstain

^ That sums it up right there. If it would break the bank to buy a whole new engine then yeah, it's not for you.

Very safe if you have supporting mods. If you don't, it's probably just a matter of time until you blow something. The stock Coyote is very resilient, but it's designed for stock power. When you start pushing several hundred horsepower and high psi boost, you'll find a weak point before too long. Could be years, could be months or even less. Generally these engines are tough though.

I didn't upgrade anything and ended up blowing my motor within three months of supercharging. Once I upgraded my pistons I haven't had an issue since and it's been three years.

I'm going on close to 2 years now (13k miles). No issues so far but I really don't beat on my car.

Just curious, have you been running a BAP for those 120k miles?

How much HP and how much boost were you pushing on stock block? I’ve read various things that you’re generally safe on stock internals up to 700HP +/-. The FP/Roush and Whipple base tunes & equipment should be fairly safe, once you start building up from there is where you start the clock on stock internals from what I’ve read. Still reading up on this stuff so I’m all ears if what I’m reading is incorrect. Like anything, nothing is 100% bullet proof either

Not a whipple but my 2016 Vortech car making 800 whp has been great for the past 3 years. These motors love boost. A buddy of mine has a 2015 with a 2.9 whipple 700whp pump gas is at 175,000 miles and is still going. It's all about maintenance and not beating on the car all the time in my opinion.

If a person is too concerned with boost, they can lower about 1.5 - 2 psi with long tube headers while adding a few ponies to boot. It may cause a check engine light without a tune update. I don’t beat on my car either. I’m running Roush stage 2 with their claimed 750 hp crank is probably 630-645 rwhp and I’m very happy with that. May note that rebuild kits to strengthen things up are available like this one from JDM. https://www.teamjdm.com/g32018rebuild/
I don’t know the cost to install, but I’ll go on a limb and say with this kit, labor, long tubes, other supporting mods you’re likely closing in on the cost of an eliminator crate engine that’s pre built. I went into modding my car knowing shit can hit the fan anytime. I just enjoy it and know it may cost me later—so be it. It’s a hobby not everyone can get into but for me I feel it’s worth every penny.

yes sir. VMP boost a pump.
I don’t drag the car as it’s a convertible but I do hard pulls on the freeway from time to time. I’m sure that helps with longevity as I don’t hit redline much if at all..

Man, that’s great to hear. I love hearing about high mileage boosted coyotes!
