so far this is the second encounter...the first one was a manual with exhaust (no headers) other then that it was stock..we did a 40mph roll...took it by about 1 1/2 until 130..he was alone in his car i had my roof open and had my gf in my car

my second encounter was a buddy of mines his is also a manual with afr intake..we did a 60 mph roll took him by half a car until 150..both were alone in the car.

btw my car is a m7 bone stock (level 3 z07)

I am a chevy guy thru and thru, but I have to admit the hellcats being 900 to 1000 lbs heavier give the Z06 a hard time. Only 57 advertised horsepower more, Mopar is conservative.

srtz06

well yes its about 900 lbs heavier but don't forget at about 120-130mph the c7z is weighs about 500lbs heavier due to down force and on top of that I'm a heavy set guy lol (350lb) so we were about same weight ....the only reason i took that second hellcat with intake was because of the c7z's gears


he had to shift one extra time then me and thats what gave me the edge

SharkbyteLT4

it helps when their advertised HP is severely underrated. It sucks Dodge has a better motor than our car has. Imagine one of those engines in our Z06s, it would be downright nasty

BJ67

I assume you didn't start from 120/130 mph, so down force weight isn't a issue. the Z06 should pull any hellcat from lower speed rolls. If I roll raced Z06's, First thing I would do is remove the all the aero. The cars have no top speed and I realize they were built for road course and superb handling.

srtz06

no we did a 60 mph roll...remember that hellcat was not stock it had intake. so right after the 3rd hank he pulled about a fender on me..it took me to 150 for me to be able to pull half a car on him...on paper he shoulda beat me..but thnx to our longer gears that wasn't the case...btw he raced can auto c7z with level 3 aero just like mine and beat it by half a car same day

srtz06

how does dodge have a better motor then us? just cuz it make a lil more hp? does stupid to say..does that mean the hellcat motor is a better more then the viper?...no

four0nefive

It's not about starting at 120-130, once you get to those speeds, the downforce will kick in. I agree on removing aero (going down to stage 1 aero) if you roll race a lot.

Here's what I don't agree on, the "no top speed comment". The stage 1 aero Z06 will do 195+ (some have done 199-200) and even the Z07 (stage 3) will do 185. Plenty fast for anyone really. I don't know about you, but how many times do people attempt to achieve a top speed?

srtz06

of course i know removing my aero would help but its kinda annoying doing that all the time...these runs were just for fun...just wanted to share my race with our people since iv seen a lot of stock c7z's loose to a stock hellcat....m7 is faster (if you know how to shift) and iv ran 2 hellcats neither stock to back my story up...c7z is faster then the hellcat

mowe

The Hellcats are very under rated. Stock mine made 686whp... That's a little over 800hp.

srtz06

wow thats insane what dyne was that on a dyne jet?

also have you ran ur z against ur hellcat?

3 Z06ZR1

So you with the M7 and (no offence) and the weight of 2 people.
Beat the Hellcat with an intake and later on the same day that same Hellcat beat the A8.
Just how I figured would happen in roll races. M7>A8 in rollraces.
I say this because of all the hype people put on the A8.
Yes it's lower gearing lends to easier faster 1/4 times. But they are not better, faster
in all respects.
Both do great things and are good choices for your reasons.

Which transmission did the two Hellcats have and were they Challengers or Chargers, or one of each?

srtz06

they were both manual both were challeners, one had intake with 305 tires, the other had exhaust with 315 tires

the one with exhaust was a lot easier for me to pull on..i pulled on it with my top open and another person next to me

h3mpking

I raced a hellcat in a half mile event and barely won. They are running the same MPH's in these half mile and mile events and some are faster than the Z06. I had a Charger Hellcat and it was surprisingly fast for the weight. I'd say in a straight line, it all depends on the driver.

dar02081961

Z07 ? M7 or A8.

Yep I agree it depends on the driver. Even more so in some cars because there is a learning curve on how to maximize the cars potential. (remember last year when no one could get a 3.2 sec 0-60 out of an M7....happens all the time now)

That said on the street it doesn't matter what you drive, if you get caught at the wrong time in the wrong gear OR if the other guy gets a jump, you are gonna lose. Been that way for years.

One of those motors in a C7 would completely block the view out the front windshield. They are FAR too big to fit. They may have a hp advantage, the LT4 is a marvel of packaging.

NytmereZ

I think he is referring more to the supercharger setup that the LT4 has.
Dodge did the blower setup right the 1st time, went overkill on intercoolers, it has both air to air and air to water, and was tested in 90 degree heat.
The problem with the vette is room, I'm anxious to see if 17 year model gets cooling updates, I'm seeing that the new ZL1 LT4 powered camaro has tons of updated cooling, but again there is much more space.
Im thinking Chevy has to do something to the Z06 now that the widebody GS s being released.

BJ67

I am a GM guy and the 707 hp hellcat is underated and doesn't seem to be affected by heatsoak as bad as the Z06. Using the Horsepower to weight ratio the hellcat should not beat a 662 hp gt500 and should not give the Z06 such a hard time. The Mopar , because its underated runs better than it should. The Z06 horse power is really what it is , not more than advertised.

BJ67

The Z06 has heat issue's, very sensitive timing controls and chevy decides to use a small supercharger that spins very hi RPM and builds even more heat. They decide on pumping the compression 10 to 1 and lower the boost. Higher compression, more sensitive to reduced timing. And I truly love Chevrolet's, but I have a hard time bragging about the Z06 to much. Love my C7 base M7, car does more than it should.
