Never owned one... but I have driven and ridden in them. How much wheel time would someone need to spend before their opinion was valid?

People get pretty defensive about their car choices...that's just how it's going to be. I shared my opinion but certainly didn't mean to offend anyone with my extremely faint criticism of the driving experience and livability of a boosted engine versus a naturally aspirated one.

If you don't mind the decreased efficiency (with SCs more than turbos), increased mechanical complexity, added weight to an already nose-heavy car, increased maintainence requirements, increased heat, more variables to tuning and power delivery...and a very particular sound that eliminates any chance at being stealthy...then by all means, go with a supercharger. You can make a ton of power with them.

Just please accept that there are people in the world who might see it otherwise.

I'm a big fan of the 03-04 Cobras and the GT500s and I'm always impressed by what those boosted motors can put out. That said, I'm not planning on buying one. They just don't suit my personal taste.

 

Anyone that even thinks about putting that on the stock coyote is dumb.
Boost yes... that high...uh no.

With a blower it'll make more than what 95% of people want to accomplish
Those other 5% can buy something else.

 

yep 6-8lbs of boost on the stock setup should suffice for just about everyone outside of the hardcore folks.

 

The thing is 17lbs of boost isn't even pushing it with the Terminator, that's what I'm getting at. Forged bottom end from the factory FTW.


To me comparing the Terminator Cobras to the new 5.0 GT in terms of acceleration is kinda ridiculous, especially if mods are involved. The Cobras are all about brute strength and power. The new 5.0L GT is a more balanced machine engineered to do all things well.

 

I haven't driven a Terminator or a new 5.0, but I have driven a 2010 GT500 Vert, and I thought it was much easier to drive than my 08 GT. Just because it has 540hp doesn't mean its hard to drive. Its smooth, and I thought the extra HP came in handy.

I want to drive a new 5.0, to compare.

 

How is your 08 difficult to drive? I find my '09 GT to be a joy...and one of the most forgiving and predictable clutches I have ever operated.

 

Don't get me wrong, the over engineered 4.6 is capable of dumb numbers (pushing large boost)
...but so is the 5L family..... more efficiently.

Even in GT form, the engine is capable of NICE numbers on little boost.
but there isn't just 1 5L ya know... I don't go to the track and brag about how much PSI I'm pushing...

And what an engine is capable of, and what it comes out with...are 2 very different things.
Case in point... 3.5TT... there are other limiting factors at play.

 

Its not difficult to drive. I enjoy mine as well, but I find the 2010 GT500 easier to drive - steering, shifting & ride comfort. Feels good to have that extra HP right there too!

 

There is only one 5.0L available in the 2011 GT, and that is the car that the OP wanted to compare to the '03 Cobra in this thread.

 

Well if you're gonna drag it back go the original inquiry, then we wouldn't be talking about a Cobra with 17psi would we...

 

No, you're right, we would be talking about a pullied Terminator making 13 lbs. and 450ish rwhp.

 

There is a local guy here with only one mod on his Cobra engine.
A large low boost whipple.
I have seen him run 600RWHP on the dyno.

 

a termi is the same weight in general as a 2011 gt. it is faster in modded form.

 

[QUOTE][/QUOTE When it comes to modding though, the 03-04 cobra should have a pretty good edge.


For now !

 

11:1 compression ratio + 7 psi = more power than a termi. termi heads flow 233 < coyote 311+.

coyote = more power per pound of boost. 11:1 is not too much. this is 2010. fuel injection can handle it.


coyote----n/a === 370rwhp
2003-2004 4.6 4v = 290rwhp(mach1)

of course screwing the termi = win for as long as the motor lasts. there are too many dusted termi's out there with ported m112's at 14-17 psi -515ish rwhp. i know plenty of them. im using the same pistons as a termi in my turbo 4v and i worry about them all the time.


i know all the stats. know all the facts.


what nobody knows is the design strength of the coyote rods. we'll all find out soon enough. is it like a boosted mach1 with a glass jaw or a boosted beast.


what i s do know is the coyote WILL make substantially more power per pound of boost than a term i. head flow, port dynamics, plus cylinder pressure will add up.

the next boosted 4V i build will have 9.1:1 compression and not the 8.5:1 i built in my current 4v.

god help termis when people put ported heads, h-beams and 2618 pistons in these. low boost(12psi) and rediculous power.



but the OP asked about running a termi. not going to do well it seems. lets see what the max bolt on power is going to be.

 

Wow a whole 450rwhp...

I wonder how much PSI it would take the coyote to make that much....

Granted terminators are 8 years older, and still quick and cheap to mod. That's not the argument. At face value, they are pretty awsome.
Dollar for dollar modwise the Cobra will smoke the GT.
