Is the Shelby GT500 going to need 700HP at the crank to keep up with a C6 Z06?

[Purvis]

from rangers sig...

the fact is a base Z is $28K more than a base GT500.

How do you figure?
From memory:
GT500 = about $42500
ZO6 = about $65500

=$23,000

I bet you Evolution has at least +$15,000 into their GT500 (in mods/labor) already. And its about the same ET/speed wise as a DR'd C6 ZO6.

Granted the EVO GT500 will be going faster as they figure their combo out...

------------ Invoice-----------MSRP
Base Price $37,018.00--------$40,930.00

------------ Invoice-----------MSRP
Base Price $61,911.63--------$69,175.00

off of KBB, GM increased the sticker price for Z06's for 07.
=Almost $30K, your $15,000 in mods sounds way exagerated as well. Maybe with a twin screw and supporting mods, I have the same power mods and am not even at a 3rd of that in my Cobra. I don't see how parts are gonna cost that much more for a GT500.

Simple Math really. The C6 Z06 weighs in at 3150lbs per the General, and they will typically dyno around 460ish (some higher some lower). To make it simple and be conservative, let's use 450RWHP, which gives it an even 7lbs/HP for a power to weight ratio. The GT500 checks in at 3920. At around 435RWHP, that makes its power to weight ratio 9.01lbs/HP. A 2lb difference is HUGE. To match the Z, it needs to make at least 560RWHP and even then that skips the fact that the Z has better gearing than the Shelby does. So, IMHO, you are talking at least 600 to the tires to beat one in a straight line. Z06's are getting easy mid 500s with headers, exhaust, and tune, so mod for mod the Shelby is never going to keep up. Put a power adder on a built LS7, and the Shelby can forget it, I don't care how much boost you throw at it.

I'm not knocking the Shelby mind you, I LIKE IT and want one. But I do find the continual comparisions between it and the Z06 rather pointless. The Z has the Mustang covered in every single category other than having a backseat, but it's a totally different beast.

this is all very true. add in the fact that the aerodynamics on the C6 Z06 are much better than the shelby GT-500 and a high speed roll race becomes that much harder for a shelby.

Yup you're right, I just double checked, The ZO6 is 69,175 MSRP for 2007:cuss:
However, Ford has the GT500 listed on their site as 41,675. MSRP.
=27,500

I think its a good bet the EVO GT500 has $10,000 in parts into it already. Add dont forget the labor and tunes it would take a customer to get everything to work.. At that point you're talking a nice chunk of change..

The EVO GT500 is definately stretching the term "bolt on".

 

[chuckstang]

I agree with purvis 100% here.
Were not even mentioning the added cost for new rods plus labor as well to really put a hurt on the z06. 700 hp I think will be too much for the stock shortblock

Guys:

The development or R&D vehicle will ALWAYS have more time and money in it than your regular Joe's car! It's expensive to develop mods just like it's expensive to develop a new vehicle for the manufacturer. :idea: :read:

 

[SnkBtn99]

Anyone remember when 300 was king of the hill ? We are now splitting hairs of 500+hp .... WOW!!!

I must be getting old ...

Yup 100% correct.
It will be fun to see just how much $$$$ (Down the road, after R&D and the aftermarket are a little more expereienced with the GT500) its going to take the GT500 to beat a Stock ZO6, or maybe even one with light mods.

The interesting thing however, is we are in uncharted territory with the amount of hp its going to take from a bolt on car, to do this...

Like others have pointed out, 500hp is an insane amount of hp from the factory. Remember however, cars in general (with the exception of maybe the Vette) have also gotten very HEAVY. The more weight, the more hp you need to move it.

 

[Fourcam330]

Realistically it will only take a 2.7-2.8L twin screw/tune for a GT500 to beat a stock C6 Z06 in a straight line. You could beat around the bush will all the regular bolt ons, etc. but if you're in a hurry that's all it will take. Cost differential wise it might also be your best bet.

Is that going to get you to 600rwhp? I dont think it would take 700rwhp, but i do think 600 is operative to win a straight line battle. Let not forget most
C6 drivers are not RANGER and cannot run 11.3 bone stock. I think 100 extra at the rear wheels would get this car easily to mid 11's. MIND YOU I AM TALKING ABOUT ON STOCK TIRES. And how long will the stock block hold at that power?

to get to their power level they have ~$2000 in parts...

o/r X $300
catback $400
pulley $180
CAI $300
stage 1 port $345
custom tune w/ xcal2 $400

All of the suspension and other stuff including wheels and brakes is probably another $4-5K in parts...IMO the brake downgrade was unnecessary...

Yes, it will easily get you to 600rwhp on straight 93 octane. With full supporting mods a 2.3L twin screw makes around 680-700rwhp on straight pump. The larger 2.7-2.8L twin screws should kick out more.
Obviously you'll need new rods at that point.
Also in somewhat of a digression, someone's built Ford GT (Boss 330 worked) just put down 904rwhp SAE on straight 93 octane with a set of twins. Less the drivetrain loss difference that should be around ~850rwhp in a GT500, 1000rwhp will be easy on 100/104 unleaded with twin 57-67mm+ turbos.

Yes you were correct on the price difference.. (I admited that earlier, since I did know of the price increase on the 07 ZO6's.)

"To get to their power level" is a misleading statement. What good is the power if they cant put it down?.. There is now way that car would be turning 11.0s if it were not for all the other supporting mods they made to the car..

-Tune, $400.00
-Pulley, $400.00
-Ported supercharger 1,000
-Skinnies/wheels $500
-Slicks/wheels $800
-Gears. $300
-CAI 300.00
-Full catback exhaust $700
-Offroad Xpipe 300
-Fully redone suspension, consisting of many things.. they had a mod list up at one point that Snorman asked them for, and now I cant find it...1,000-$2,000?
-Replaced front seats with light weight racing units, and other various ligtening 1,000
-No to mention the rollbar / custom shifter, etc. $1,000

Add up all these up and you have 8-10,000 in parts IMO. (just a rough guess of course)
Add in the labor and you have at least a few more thousand, if not more.

I think to duplicate this car at this point, for someone who did not own a shop, it would be around 10,000-$15,000. (give or take a few thou)

That sounds awesome. Thanks for the info Fourcam.

Well actually you are making that out to be the best time a Shelby will ever run. A stock Shelby has run 12.1 on ET streets. How much is that mod? Add a tune and pulley or just a better supercharger and 11's are a short period away. I think on stock or some PS2's or BFG KDW2's the Shelby can get to the low 1.8's 60' with a really good driver. Add some awesome track conditions and it's very possible for this car to go 12.1,12.0 maybe an 11.99 bone stock. Not to mention all the power gains from just a tune.

You are really pulling for straws to try count the roll bar like it really helps you go faster. Any car has to have one to run those times so its a wash. also the seats are a wash too because many times you can buy race seats and sell the stock leather seats and come away with some extra cash. I've done it. Tune, Pulley, CAI, Full Exhaust are 4 of the most common mods to any car and are not all that much. But the Mustangs have been one of the cars that has benefited the most from their adition. Maybe Evolution put that 8k in to their car but I would bet it wouldnt take that much to get a GT500 into the low 11's.

[chuckstang]

with the amount of mods and money put into evos gt500, it should be running 10s IMO
If they already have then, I stand corrected

Compairing modded cars to stocks cars… gotta love it.

Chuck:

He ran a 11:06. It's not going to take much to get it into the 10's. :rollseyes

We're splitting hairs here!

That is a 10 sec car. I wouldnt consider it a Z06 killer as stated because the skinnies cant drive on the street and after 100 where the aerodrag will kill the shelby. Ture enough it will be most at the drag strip but on the street or highway it may be a different story.
