The LS3 Vettes arent putting down 500 to the wheels with a Cam only. They put down mid 400s. A friend of mine has an LS2 C6 with the L92 heads and intake (pretty much an 08 LS3) and he has LT, Catback , midpipe, ported the heads, semi aggresive cam, and poted intake and TB along with a custom tune and he is only putting down a little over 500rwhp.

GT500 although puts down impressive power (mid 400's) would be out run by a C5 Z given everything equal. Thay are not geared as well, as aero dynamic nor as efficient as the Z. I am not even sure I have seen any high 11 passes from them bone stock to the tires, and usually trap 113-116 with a few freak 117-118 passes. For the power they are not as impressive as they sound. I would rather have the old termi cobra's with their motor to mod as oppossed to these. Lets not even get into the C6 Z. Give me one of those, cammed, long tube, intake and tune, and you will see me as one happy 550 RWHP owner that will own most of the stangs except the most extreme pushing in upwards of 700 rwhp or more. Light weight and powerful rules.

Just my 2cents!

I got $10.00 that says the Vette took him.

 

Then how do you explain the power to weight ratio? There are PLENTY of guys on the corvette forum with low low 12 second passes in there stock C5 Z06's.

If you think the GT500 weighs that much why does Car and driver, automobile and every car website list it at 3920? Edit - Car and driver lists the GT500 at 3896...

"The major reason is the GT500’s weight and how it is distributed. The hardware needed to turn the 5.4-liter DOHC V-8 into a 500-hp monster makes for a long and massive list. There’s the supercharger with its drive pulleys, the intercooler with its pump and water lines. Even the 5.4-liter heavy-duty block weighs more than the 4.6-liter assembly in the Mustang GT. All told, these parts add about 150 pounds to the car — most of it up in the nose. Combine those extra pounds with the GT500’s large brakes, 19-inch wheels and tires, and six-speed transmission, and the result is a porky 3896-pound Mustang."

welcome to my friday and saturday nights

 

Now what would make this race even better was if an srt10 hensessy viper or an ford gt were there.

 

Wow you proved nothing first you said cam only, well the car has LT Headers, which means it also has a midpipe and KN Intake. Do you not think those things add power? Hell LTs is good for 30-40rwhp on those cars and the intake is good for 15-20rwhp. Also you dont know the correction on the dyno and what dyno it was done on, a Mustang Dyno and a Dynojet will give you two totaly different numbers.

As for the timeslips on the Z06s there is only two guys with slips to prove what they ran, first Ranger which is one of the best drivers out there and makes up about .0001% of the people that own those cars that can drive that good and the other guy which Ive never heard of but must be a very good driver.

Of course your going to have guys that run low times and they have been out long enough to get those times the GT500 has been out for a little over a year and most of the cars went to old guys that are storing them or guys that dont know how to drive for ****.

Oh by the way I weighed the GT500 with me in it and damn near a full tank of gas and the car weighed right around 3900 and I weigh 180. The scales might have been off but thats what the car weighed in at. Also for the power to weight ratio you also have to remember that these cars make peak power very quickly.

And the guy that said hed rather have an 03 Cobra a GT500 is nuts check out the power these cars are making with a Whipple 3.3 700rwhp+ on 91 Oct. Cali gas and 800+rwhp on 110 Oct.

 

i love the people that say, "id rather have a termi than a gt500, the gt500 is so heavy!" all car and driver babies. stock for stock, and mod for mod, gt500 is a way better car, and it's a drivers race between a c5z and a gt500, but onyx you are forgetting how much harder it is to launch that z. IRS is hell in cars with that much power compared to a solid rear, you probably know that and although i agree if both are raced to the best they can be, the z will pull, but if you throw average drivers in both the gt500 will be launched more consistantly and will most likely pull. on the other hand, alot of people driving around z's now actually buy them and use them instead of buying them as weekend cruisers, so you never know. Drivers race without a doubt, definately NOT 9/10 win for either of them. once you start modding though....oh boy bye bye z.

 

Z06 Won...my friend works at a ford dealer and he drove both the gt500 mustang and the corvette z06 07(manager bout the z06 from another dealer)he said the z06 would murder the gt500 with no problems

 

that is like something that you would see in a movie lol.

 

+1 Thank you!

Dont get me wrong guys I love Corvettes and sometimes I wish I would have looked into a used C6 Z06 or even coughed up the extra dough and bought a new one but I bleed blue. I know many many people that own Corvettes and I do love the looks of them and how they ride. I have 2 friends with 06 C6s one stock and the one I mentioned earlier, 1 friend with a new 08 LS3, one with a 07 Z06, and two with 02/03 Z06s. I know they are no joke and respond to mods very well.

ovioulsy mid-low 11sec car vs mid-low 12sec car.

 

sry but never seen one round here. although have seen a evo with a gt42 pushing 1000 plus horse on the street once. (i've seen him at a local show thats how ik bout the numbers) it was a local shop that had built it and they were using it to advertise their work.

 

When i stated "Cam Only" i meant LT's as well. No one runs a cam on stock exhaust manifolds.

Who told you that Z06's are hard to launch? My C6 was a breeze to launch and have launched a C5 Z06 before and found it very easy during a race. Maybe it's just some drivers.

As for mod for mod. The LSX LOVES N20 and big cams

 

What?? Cam only means.... well.... cam only. Im not trying to be an ass but thats like saying cam only and having ported heads on the car and saying no one runs cams without ported heads. Plus I know tons of guys that have cams on there LS1s and LS2s and anyother car that dosent run Headers. I didn't have headers on mine for like 6 months after I put in my cams.

Also yes LSX do love head and cam and nitrous. I wish Mustangs responded to heads and cams like the LSX motors do.

 

To the LSX circle "cam only" means cam with exhaust work which is usually LT's. As for your friends who run cams without headers? Kick them in the ***** and have them order a set of headers. A cam before headers is nuts unless they're running the "CheaTR" cam which is fine for stock manifolds. When you step up to the 230+ duration boys then you really need headers.

Edit : If you look back to the LG dyno i posted. Even the title stated "2008 C6 LS-3 dyno with LG Motorsports G7X-4 cam only".

 

i know z06's are harder to launch than alot of cars i've driven with similar power. I absolutely HATE IRS when it comes to launching though so maybe im a bit bias. I agree on the n2o thing, but you gotta keep in mind, a good cam and n2o setup that you can run safely is gonna cost upward of 2k.
http://www.evoperform.com/GT500/dyno2.wmv

if you look at the mods that would actually yeild any power gains...probably less than 1200 bucks total.

 

To the person that was questioning me about choosing a 03-04 cobra over a GT500 (04 yellow GT), the reason would be strictly power levels on a stock block basis (on top of the added weight). The 500 is more comfortable by far for my 6'5" frame. Talking about power levels though, both are semi similar except for one major player, the connecting rods. Where both cars use a iron block, forged crank and forged pistons, the 500 uses forced steel connecting rods where as the termi's use forged units. That right there is the difference on handling the power leves of the termi cobras. They have gone 900-1000+ hp on the stock short block, not so much with the 500 I have seen yet. Not saying it can't happen, it does have more displacement, nothing yet has been proven that will last more then a few dyno pulls though. Anyone want to correct me on this statement? 03-04 stock short block>GT 500 stock short block.

Some other points, mod for mod between the two is about equal to an extreme point on the stock block. I will keep emphasizing stock block so as not to seperate from stock versus modded blocks. I completely agree about the IRS versus solid, no question there. But mod for mod take out the launch part and I will give the edge to the termi's.

Yellow GT, I do believe the scales were off! No question about that.

You Ford guys feel free to correct me about the power levels of the cars. But I have read many of times of the power levels of the termi's, and my buddies 03 on a stock motor with a procharger and tune with cat back and a different filter made 618rwhp easily daily driven on 93 octane. No intake change, headers, cams, heads or anything. That really impressed my being a die hard LS GM guy. Although he was beat semi decently by a Ron Fellows cammed, long tube, intake, tune C6 Z06 at about 550 ish rwhp. like I said, please correct me if I am wrong about the stock short blocks and materials and power levels. I have note seen a GT 500 at the marks of a termi yet as realiably as the termi's.

Time to open the bomb bay doors, and 3, 2, 1 release.


Sorry Mustang lovers but when it comes to VETTE vs GT500 the only Z06 that will be a drivers race is the 385HP early Z06 after that the GT500 is dead.

A LS2 powered C6 Z51 is a drivers race for a GT500, the new LS3 would just walk away and the C6 Z06 would run away from a dig or roll.



And you just gotta love the universal failsafe when it comes to Vette's, GTO's and 03/04 Cobras. " But the IRS is harder to launch " or " The IRS won't get of the line faster "

But you know what if you've never played golf it will be hard, if you haven't shot a gun before you won't hit a bullseye. It's no different with IRS.................

 

yes it is. and a c5 z06 IS a drivers race for a gt500, if you don't believe it you are wrong. They are both low 12 sec cars with the proper driver, but like i said the z is a bit faster if both are driven great. The IRS thing is not a failsafe. why in the hell do you think people swap out the IRS on termi's fairly often? and obviously a c6 z is gonna walk a gt500, that i dont think anyone could deny. and an ls3 would walk it too.

 

You are right to a certain extent BUT you have to look at the stength of the rods, pistons and crank put in both cars. Just because it says forged dosent mean its indistructible. Thats why they make pistons good for 500 hp and others good for 1500hp. The 03/04 Cobra shortblocks are strong but they still have a limit and 550rwhp is where you can run those cars forever and not have to worry about anything, once you start passing that its start to become more and more of a risk. John Coletti said that himself. I have never seen a 03/04 Cobra put down 700rwhp on stock block hell Ive seen 2 guys blow the with around 600rwhp. There have been numerous people put down 700+rwhp with just Whipple 3.3 on there cars. A friend of mine sells hoods and his hood is the only one out for the GT500 that fits a Whipple or KB underneath it. He has talked to numerous coustomers that have bought his hood and put either blower on and they are all making 650-700+rwhp on pump gas, depending on pulley. Like I said earlier the one guy made like 700rwhp on 91oct Cali. Gas!

Its a fact though, that if you put a KB or Whipple on a GT500 and a Termi with same boost, the Shelby will win without a doubt.


Where are you getting you info at. The C5 Z06 made 405hp and the new 05-07 C6s make 400hp and they weigh close to the same. So how is a Z06 a walk and a C6 a divers race. The new LS3s are faster but the fastest my buddy has ran in his was a 12.4 @ 114 with a 1.9 60'. You keep forgetting all the LS2-LS3s have tq management that dosent let those things launch worth a ****, hell your GTO has the same thing. No racing from a roll is a different thing a 405 will beat a GT500 and the LS3 would pull it too but not by what your thinking.

And yes I agree 100% with you that a C6 Z06 will MURDER a GT500 from a roll or a dig.

As for the IRS, have you ever drove a high hp car with IRS. A person can master launching a stock Corvette, GTO, and Cobra but, try driving a 550rwhp Cobra or a stock Z06. I've been in both and they are handfull for even good drivers.

 

gt500 are slow turds without any serious mods...the new zo6 is wicked stock enough said.

 

i drive the new z06 all the time at work. they are so ******* quick that i never pass up a chance to drive one. i havent got to drive a gt500 though, best i got to drive was a roushe stage 3. to me it was way more fun to drive because the supercharger was crying and since its shorter more rear end fun

 

I guess a 03/04 Cobra is too since a GT500 is faster stock and modded. Yes a Z06 is CRAZY fast stock though.

For some reason Im guessing your Codys friend.

All else aside

Have you looked into the 2.6L KB you could really make some big numbers then! There is a guy over on Stangnet making like 670rwhp with the 2.6 @ 15psi. The cars sick to say the least.

Also how are you spraying? Im looking into nitrous (100 shot) and am looking a spraying right before my IC.

 

look at the power to weight ratio of a 03/04 cobra and then to the gt500... the best bang for the buck is still the 03/04 cobra(**** ton of mods that are cheap). yes the gt500 runs a little better quater mile but for having 100hp more it should. they are heavy. plus the price of a gt500 is outragous just because of the shelby logo on the back.

I spray after the MAF in the intake tube through the supercharger(Wet shot). havent done it yet because i have to upgrade the wiring to the FPDM and twin GT pumps. Joe at Excessive autosports said that i need more voltage to them since there is only a 16gauge wires to them and the FPDM.

On the 2.6L idea. I bought the 2.2L right before they changed to the 2.6H trust me i was pissed. Thing is they arent running them on 91 octane fuel. They must be underdriving the supercharger because from kenne bell the 2.6H with a 2.75in pulley and stock 6.5in crank they run 18psi not 15psi.

what kind of supercharger you running. If your running one through the stock intake. then get the plate system or the fogger system that goes under the injectors or you can do what i did and get the EFI kit which put it were i have it. for a wet shot run it off the shrader valve on the passenger fuel rail.

The dyno wants me to run e85 but i have to get bigger injectors 60lbs to 75lbs. They said on a NA mustang gt they got 40hp out of it. I dont know if he ment crank or wheel. He said i will be well over 600rwhp. Plus with the 110 octane i can run a 18*degrees of timing and get even more power. And i have the belt slip problem fixed now so haha full 18psi and 19psi at redline.

Yes im codyss friend...
