Street Racing & Kill Stories - 2011 C6 ZR1 vs 2013 GT500

I Didnt see a thread about this race I think everyone will enjoy it..

Air filter/Tune 2011 C6 ZR1 made 535rwhp on Mustang dyno (around 560-570rwhp dynojet
Pulley/Tune/CAI 2013 GT500 somewhere between 650-700rwhp from what I've read at SVTPerformance

Enjoy

60-150mph

good run, but those cars are definately closer in hp. 535whp is very low for a stock zr1... nevermind one with a couple bolt ons and tune. I say the gt500 has maybe 50whp on the vette which is not enough to overcome the weight advantage.

Another high HP car destroyed by it's weight....

When will manufacturers learn.

Way over 50rwhp maybe 90-120rwhp ..
ZR1 is around 570rwhp on dynojet maybe less the GT500 with Pulley/Tune and CAI is proven easy 650-700rwhp
But yes Good run and GT500 ran great with weight difference

easy with offroad x pipe... its hard to push all that through stock cats. If it had an x pipe i would agree with those hp numbers. My guess is its right in the 650whp area. Theres a 600lb difference between the 2 cars. If it truly did make 120whp more then the vette...thats more then enough to cover the weight difference and the gt500 should have pulled. Idk maybe the driver wasnt fully there in the gt... vette driver was pretty good. Either way, i want a z06

With stock cats he right not making 700whp. Maybe 670whp at most. With a dyno tune.

good runs tho...

One evolution had made 733 with those mods a dyno tune from what in 5.0 mag.

Svtp someone just posted it made 670whp/700wtq

Nice runs! Results look right on the money. :D

WRONG! In stock trim, most ZR1's will put down 510-530 on a Mustang dyno. My car did 541whp on a 248 Dynojet if that helps. No way a ZR1 with those mods is going to be close in power numbers to a '13 GT500 with Pulley/Tune/CAI. It's been proven to see ~50whp with just tune alone, matter of fact a sponser here saw 45whp I believe.

Diablosport made 617whp on a conservative dyno with tune only. Add intake and pulley to that and do the math. lol And 600lb difference? :confused: Where'd you get that from? It's long been known it takes a GT500 a crap load more power to run with a C6 and this one is no exception.

The ZR was starting to check out pretty good when they let out.

First of all... calm down...

Second of all.. The new gt500 isnt the old gt500 platform. Diff motor, diff blower, diff aero...everything is diff. A 600whp bolt on pullied 08 gt500 will get walked by a stock 2013 gt500 that makes the same whp. Unlike the older gt500s, the new ones actually run the ET and traps they should for there power to weight ratio.

GT500 weight - 3850
ZR1 - 3250
= 600lb difference.

As far as power is concerned.. Evolutions car made 740 with pulley, tune, and a full exhaust (longtubes, no cats, high flow exhaust). ALOT of that power came from the catless x pipe. You arent pushing massive power through emissions legal cats. Its not happening. Almost everyone i know who has tried that, has ended up with missfire issues or there cats ending up in there mufflers.

Evolutions car trapped 142 with 740whp. So if this car makes 700, it should trap roughly 135-137... and it got pulled on pretty decently by the zr1. So this zr1 traps 140?

Svtp someone just posted it made 670whp/700wtq

thats a number thats more believable

meh.. roll race

Both cars in stock trim it would have been even uglier. The Zr1 simply outclasses the GT500 in every way. The mustang held its ground however, but nothing too surprising here.

Not too shabby.

Corvettes are so sexy

ZR1 is fucking king.

First of all... calm down...

Whoa Billy...let's not get offended here. I was simply stating your claims were all wrong that is all. Just telling it how is, no offense intended. :)

I'm aware of this. The old ones ran the number too with a better tire than what came from the factory. Also, look at how the '13 GT500 stacks up stock for stock with a C6 Z06: Roughly 700 pounds heavier but with ~150whp advantage yet the C6 Z will run at its door in a drag and roll race. Think about it...

GT500 weight - 3850
ZR1 - 3250
= 600lb difference.

A close friends '13 GT500 weighed in at 3750 without him in it. Another '13 the same day tipped in at 3771. For comparison, a 2011 ZR1 will weigh in at around 3350 dry. Closer to a 400lb difference between the two. The '09 Z's like my current one without Nav, side airbags, etc. weigh in the least at around 3320.

I'm not saying the car in question is making 740. What I am stating is its surely a much larger gap than than what you stated, and the Mustang is making atleast 100whp more than the Z with those mods.

I'm not sure what this car traps. All I know is its going to take more than what its got to run with a intake/tune ZR1. :devil:

A ZR1 is closer to 3350 as it leaves the factory.

I'm trying to get a run with a stock zr1 from a dig. He's on stock tires :devil:

Lol C'mon.

Good run. Dude with the ZR1 can drive pretty well.

Not going to lie, I got scared for a second there. ZR1 came through as expected though. Those '13 GT500's sure are a force to be reckoned with though!

Keep in mind a h/c z06 making the same power as a zr1 will roll out on a zr1. Ive seen that many times... the z06 is in a world of its own.

Due to the 200-pound weight difference yes, you are correct. Had GM managed to make the power the ZR1 makes while keeping the weight to a Z06-like 3100lbs the world would have really been in trouble. :)

Does a CAI really do anything for a 2013 GT500? I saw one at the track Friday and it looks like the stock piece would be hard to improve upon.

no.. it comes with one. Evolution and lethals cars use the stock cai. There is literally no point to changing it. The main power adders to this car.... pulley, tune, x pipe. X pipe is probably the most important since stock cats can only flow so much air no matter how much boost. GT500s pick up almost 40whp with just an offroad x pipe.

I dont see how it wouldnt benefit especially on a blower car.

Lol C'mon.

ima fuck dat bitch up

ima fuck dat bitch up

Rolls are for fat chicks

Rolls are for fat chicks

i know thats why we be dig running and at around 120 I stop because slicks are unsafe on streets so trolololol zr1 kill here I come.

^Not true. There are good gains to be had with a CAI over the stock airbox. C&L picked up almost 20 peak HP on the stock tune. Diablosport also saw gains over stock though not exactly sure on the numbers.

This from C&L:

The installation of our air intake upgrade, without ANY computer tuning adjustments delivered average gains of between 17 to 18 peak HP over stock with torque improvements of anywhere between 20 to 27 ft/lbs in the midrange (4,000 to 4,500 RPM) over the comparable factory baseline testing. We have provided charts that show both the “best” runs for the stock air intake and our upgrade assembly, along with the second “backup” pulls in each configuration. You will notice that with the stock baseline testing, power dropped off more noticeably with the factory air intake assembly on the second test than it did with our upgrade assembly, delivering more substantial gains than what was shown in the “best” pulls for each configuration. For each corresponding backup pull, we saw similar gains to those represented by the two examples provided on this page. This shows a clear trend that the installation of our upgrade air intake assembly delivers a consistent and solid gain by itself on even a completely stock 2013 GT500 vehicle.

There is also a dyno graph comparing stock vs CAI in the link below:

But I thought you was the roll king ? Lol

That's like 2 months ago. I have slicks now.

I do remember back a few years ago C and L stuff and their claims were garbage. Lee Bender was sleezy but no experience with their new stuff.

I find no reason to see 15-20whp for a CAI unreasonable, ESPECIALLY on a blower car. I'd be willing to bet those numbers are very realistic in terms of real world.

Secondly, I've purchased many items from C&L dating back to my pushrod 5.0 days and have never been disappointed or saw any "bogus" claims with their products. That has been my experience with them.

Looks fairly well designed to me.

Yes it does! However I prefer testing and hard data to pictures myself. :)

Hey GT500 guys,


can a 3.4L whipple GT500 push 1134rwhp lol? There's a guy claiming his is 1134rwhp and wants to race me. I said sure from a dig no problem. I'm thinking his car is probably actually only in the 7-8xx and with his street tires he ain't going no where.

With a 4.0 or 4.2L maybe but a 3.4 I don't think so.

Guy is full of shit... the most he will push out of that set up is 850rwhp give or take.

Should be a low 10 sec at right around 140+mph...

jesus that thing is a big engine.

Good runs! ZR1's just don't play nice.

To clear up some confusion about the GT500 dyno numbers this was posted in the other thread:

To clear some things up...

We tuned the gt500. It made 680/722 on our superflow.
Its making 700 ft/lbs by 2800 rpm. I don't think the roll speed matters too much in this case, the torque curve (plateau?) is nuts. Had to roll into the throttle in 4th gear on the dyno to keep the tires from spinning...

And for reference, the ZR1 in this vid has Intake/Tune and put down 535rwhp on a Mustang dyno, right on par with what OP claim for the ZR1 in the video.

I don't have an experience with their kit for the Gt500. However their MAF meters for the old 5.0 were terrible. A lot of cars couldn't even idle with them. How anyone can claim a HP increase with one(they claimed 15 at the wheels were criminal.

2 reasons why C&L sucks in regards to their meters....

1. Tolerance stack ups - There is a tolerance associated with physical machining. The sample tubes can vary, as well as the housing diameter. In OEM and other Aftermarket meters this is corrected for by the fact that the meters output 'calibration' is done after the sensor is installed. OEM and other Aftermarkets literally put the meter on a flowbench. With C&L you are dropping in a stock sensor, and hoping for the best.

2. Sampling Location - Airflow is not even around a turn. Think of water flowing down a straight creek, then coming to a sharp right hand turn... The inertia of the water will make the water want to run to the outer edges of the turn. Air does the same thing. You feel this inertia when making a turn in your car; we refer to it as 'g-force'.
Now think about where the C&L flow sampling is done.... On the very outside edge of the inner diameter of the housing.
This is why 'clocking' the C&L meters can be so critical to their performance.

Issue 1 can be correctly fairly easily with tuning, but it takes time. Usually the dyno shops aren't willing to spend any more time on a car than they have to, so that they can tune more cars per day. They want a meter that is FAST to calibrate.
Issue 2 is more difficult to correct, as it takes special care in the intake tract to keep sharp bends away from the MAF.

C&L really does suck. It is by far the work MAF option we have for Fox bodies and their HP claims in ads were flat out wrong. I won't even go into their claims for 2valves and 3 valves I had experience with.

Now back to the thread....

I ran their 77mm MAF on my '92 Coupe for 20k or so miles with no issues. Ran a couple on my modular two-valves as well, no issues there either. I personally have had good luck with them. Sorry about your experience though.

you saw the pic... there is no air box... like i said... evolution runs the stock cai... they make 742whp with pulley, tune, exhaust...

you saw the pic... there is no air box... like i said... evolution runs the stock cai... they make 742whp with pulley, tune, exhaust...

Like I said others claim there are gains to be had with a CAI, but none of us will know for a fact until a kit is actually tested independently. But even if you are right at least you would have gotten one thing correct in this thread. lol :poke:

Good run. Dude with the ZR1 can drive pretty well.

Not going to lie, I got scared for a second there. ZR1 came through as expected though. Those '13 GT500's sure are a force to be reckoned with though!

I was hoping the ZR1 didn't let me down. Waiting to see the Z06 & GT500 both in stock form.

Why I love high HP street tire cars? they cant hook worth shit and -100rwhp will eat them alive if you can hook.
