Rumor has it GT500 make 638 rwhp with mods

[crispy23c]

Yeah, I'm just the wreckless one...tossing numbers out of my arse! Hey, that's like getting an extra lawnmower, strapped on for free!!!

FWIW, 575 flyweel HP is more than enough to get a 4050lb (200lbs driver) bone stock GT500 into the 11s @ over 120mph. 750 flywheel HP (638rw) is enough for a 130+ trap and 10 second slip with sticky meats.

In a factory car. This is our muscle car era. Better enjoy it while we can. It won't last forever.

We better start a savings account for tires right now.

Agreed.

LOL, or start buying shares in the rubber co's/crude oil bus. :beer:

Brad posted this morning that a stock GT500 dyno'd at 489rwhp. That is all the detail he gave except a warning that it had not been emissions tested yet.

My friends, in the words of SVT "you will not be disappointed."

if that is true, i am saving my money rite now, hopefully can get a used one in couple years for about 30 grands :banana:

on the other hand, if it is true, i think this car gonna kill all of Chevy and Dodge that coming out with their N/A :-D

Hey Fourcam330,

When is the right time (what mileage?) to get a baseline dyno.

 

[gmynko]

Anyone know if the stock engine will be able to handle a twin screw pumping RWHP up to around the 650 mark?

 

[meaty mac]

I don't know what you mean by extra info, but, it is the Eaton Roots M122h. It is larger and more efficient than the Term's Eaton..

it is more efficient, but it is the same size.

 

[Fourcam330]

It's larger.

Hey Fourcam330,

There's really no wrong time to dyno, but I would expect a GT500 to make more power with 3000 miles on the clock than it does with only 500 miles.

 

[ifryrice]

It's larger.

then why the same 122 designation. doesn't that mean 122 cubic in?

 

[meaty mac]

yeah, i thought that just the rotors were different, but if i'm wrong, oops!

 

[meaty mac]

then why the same 122 designation. doesn't that mean 122 cubic in?

that's what i thought too. :shrug:

 

[crazyhorse06]

Wasn't the previous M112?

 

[snatchss454]

2003/4 Cobras have an M112. The GT500 is M122. Both are CI displacement numbers I believe.

no no no, the previous roots was the M112, while the new one is the M122H. not quite sure what form of measurement the number is suggesting but im pretty sure its the size designation.

i must say, i never thought i would see the day that we would be getting anything much over 500hp under $100k, let alone $40k.

edited to say that snatch beat me to it.

Cubic Inches. Yes that is it. The extra volume means alot. It is basicly a 2.0 liter blower.

 

[meaty mac]

oh, okay. thanks!

 

[snatchss454]

Quick question...Can you add the CI from the blower to that of the engine for a total displacement? For example 4.6L=281CI + 112CI from the Eaton for a total of 393CI? 5.4L=331?? + 122 = 453?

That is no lie! I need to start buying stock in a tire company.
