🔧 BUILD The Replacement for the Cobra. V: “Greasy’s Fuck Your Blower-Coyote, Super-Secret Stick-Shift Hellcat Build”

[Jeffs FRC]

Joe’s garage door spring I’m dying!!!

 

[Pressure Ratio]

Technically it's more like a screen door spring.

We should call it correctly from here on out. Screen door spring. haha

 

[1quick]

Oh yeah you spinning the motor until 7,500 rpm while I am shifting at 6,300..........

7500 is pretty low for a coyote with oil pump gears

 

[1quick]

8k+ or bust

 

[greasy]

I was being conservative!

 

[BOTTLEFED]

Wtf is goin on in here?!

Well I mean you got that massive 6.something liter them tiny little 5.0’s gotta pick up power somewhere

I spin her to 8

 

[greasy]

Basically doubling my shiftpoint......

 

[Jeffs FRC]

Lol if that’s basically doubling, then the size of that mountain motor is basically double my tiny little 5.0.

Right, I am using your logic . So our motors are equal based on displacement + RPM.

You: 302 that spins to 8K Me: 376 that spins to 6300

What you lack in cubes you make up in RPM. The differences come in because you run a bigger blower, more boost, and are about 700 lbs lighter. You better be faster!

 

[Jeffs FRC]

You meant LESS boost, right?

 

[greasy]

You meant LESS boost, right?

Nope. I’ve never measured how much boost my car makes. A 2.85 pulley should make about 15-16 psi of boost. You are right there with me except you are running long tubes and cat deletes, so you are actually more efficient than me too.

The facts keep adding up ?

 

[Jeffs FRC]

My pulley setup typically makes 14-15 psi on other Cars similar to mine. 14-15<15-16. Let’s just call your slight boost advantage and my headers a wash.

We gotta line up again come spring, if you can make it out...

 

[greasy]

We can line up and I am confident you will whack me.

You only make 10lbs!!! [emoji1787]

 

[Jeffs FRC]

I’m still wondering why it only read 10lbs...

With you on some sticky tires it should be a pretty good race Id think.

 

[BOTTLEFED]

I think you should bring it back with small pulley so it reads 16lbs and see where your at [emoji4]

Have a mechanical gauge now and I’m gonna dyno at Drews once clutch is broken in. Gonna tell him to let that fucker eat to 8k!!! Mike was scared to rev past 7500...lol

[greasy]

I can't keep track of all of Jeff's pulley changes......

 

[Jeffs FRC]

1 pulley change is pretty hard to wrap your head around when you’re that worried about those pesky cookie cutter Mustangs!!! Lol

 

[Jeffs FRC]

It’s not an LS...

 

[greasy]

Shit I ain't worried, just funny how much real estate I have in your cabeza lol
