[MadCow]

There's another one S/C GT350 up and running it seems. Sorry if someone else has already posted it.

Numbers are horrible. They also shut down before 8k

680 RWHP is 'horrible'??

 

[krt22]

If that is on pump pretty respectable...E85 or race gas its quite low

Yes. That's pretty much 93 pump coyote power with a whipple and no other bolt ons.

Lethal performance GT350 put down 819whp catless and e85. 139whp is a chunky difference.

Since its called the HPE800 we can guess they were shooting for around 800 crank HP. 15% loss and not a HP more.

pass.

I bet this one lasts longer

when your at almost 2x the factory rwhp things will break quickly

Yes, but then you'd have something to talk about. At 6xx, you just have the same power as a supercharged Coyote and you've removed all of the "interesting" aspects of the FPC setup, IMO.

Only Transmission losses are not a % in the real world. Put 200hp and 400hp into the same transmission at the same RPM and you don't double the HP absorbed by the transmission. Do you think a 800hp supercharged mustang GT really is eating double the HP over a stock GT? Where is all the aftermarket coolers to keep the transmission from boiling the trans fluid and burning the seals out.

Agreed! Going with a sc is rather foolish with the FPC platform.

Last time I checked the hellion tt kit made 949 rwhp with the coyote.

818 rwhp supercharged isn't worth talking about either

Supercharging a 2015-17 Shelby is just sad and doesn't respect the car in my opinion

Today I learned from Mustang_2015 that we need to respect cars by not supercharging them.

819whp on a s/c engine with no bolt ons but cat deletes isn't worth talking about? A turbo kit will make more power. Can't wait to see what these FPC engines will but down on boost.

Don't really know honestly. Since different types of cars use all different kinds of drivetrain components there couldn't be a one size fits all rule for loss. And every car is different even amongst the same make and model. So without testing on a chassis and engine dyno it would probably be impossible to know exactly, and even the dyno's differ from one to another. 15ish% is what people guess for a manual trans so I am assuming thats where they decided to stop upping the power.

But I'm not tryin to turn this into a physics thread

Yup just thrash your engine and drivetrain, make my car more valuable.

Might as well of had just a regular 5.0 and supercharged it no point to have the 5.2 FPC makes all the engineering in the engine pointless

Lets see how long or how many miles till there is a post about a "blown" engine
