My friend ordered his C6 z51 6sp package and is getting it in a month or so. I wanted to know how do you think my car will stand up against his?

I have 04 350z w/ APS ST , APS Plenum , Exhaust Cutout
Dynoed/tuned the car during winter and made 392Hp around the same tourque(dont remember).
Please let me kno what you think, or maybe some of you actually had an experience with this car on the road!.thnx for the help

 

i know that before i took my car to put it to 8lbs of boost i had 4lbs of boost on the aps TT pushing 386 whp and i beat a new c6 by about 3 car lengths

 

386whp on 4lbs. of boost? is that even possible?
but if you say its true then thats great news for me lol!
thnx

 

He has a TT vs your ST set up.

Curious whats an exhaust cutout?

 

you had posted that on another forum i read and you never posted dyno slip of it.....I may have to raise the but oh well who cars. back to the thread to tell you the truth what kind of race are you talking hear 1/4 mile or just a roll on because i know for a fact that they are strong up top...

 

i belive they are making more then 400 to the wheel dont quote me on it but im almsot sure of it. And the car is light has nice gearing you may need to up your boost ...... im sure others can chime in though

 

Sorry, i am talking about a race from a roll. We are planning on doing 40-140mph run.

silk- I am talking about a C6 vette. NOT the C6 ZO6.
there is no way the normal C6 vette is putting down more then 400hp. Its rated at 400hp to the crank.

 

the C6 LS2 engines are underrated and make 340-350whp with a manual

they're closer to 410-420 crank hp

 

so are you saying that it will beat me?

 

i dunno, hard to say

we'd need to know EXACTLY any and every mod you have on your car.

What wheels and tires and sizes do you have

how much weight have you taken off - spare tire/tools, windshield washer fluid, misc stuff like sound deadening and plastic

what trim and year Z do you have

do you have the stock stereo or a big pimp 200 lb one in the back of the car

any other mods?


you probably can beat him most likely, but some people pimp their ride so much and make it slower than it can be

 

ST should take a stock C6. You should have a solid 50+ whp on him

edit: The car is capable, but the driver may not be

 

yeah but even 50 hp can be negated if the car is fully loaded with big rims, a big stereo, and crappy tires - dealing with that stuff is just as important as power

 

still, within reasonably similarly equiped conditions for both cars, the single should have no issue with a stockish C6. I know blake has pulled on them pretty easily with his.

 

It should be a good race from a roll both your HP is even up he is about 200lb lighter then you and has better gearing. I assume you are both manual trans. Even though your car is boosted dont be supprised if he starts pulling away slowly at the end these cars have some insane top end pulls that start around 100-120 mph.

You see them on more demestic's then you do on imports.

 

i have an 04 Touring 6sp. no system / stock wheels / tires / no spare. Mods were listed in 1st post- APS plenum, APS ST, Exhaust Cut-out(which means im running an open downpipe), tilton clutch/flywheel and tuned for 8.5-9 pounds. Other then what that i did not gut/remove anything else from the car.
Also i ran at the local track here (Englishtown) with my stock tires and ran a 12.9 @ 116. (terrible launch / spun bad)
I NEED TO WIN THIS RACE GUYS!

 

I did not even know they made cutouts for these cars! That **** must be loud as hell. I did not know you had a touring so you are more like 200lb heavier then I thought. so the vette is around 400lb lighter then you. I would say my hounist opinion thinking that you both have the same stick driving skills that you are going to lose. Not that I would'nt love to see you post a vid of you beating this guy. Make a vid whatever the outcome. good luck.

 

Stock C6 Z51 runs around mid 12's @ 112-115. so you have better top end in a 1/4 but the C6 starts really pulling in the 120mph and up. Get him from a roll and end it at 120 and you might win but better traction will help. Its going to be close from a roll.

 

you should win

especially if you have a tilton clutch, that negates the weight added by the touring model

the C6 doesn't really have "better gearing" just different gearing. It's setup to have a weaker 1st gear because a big V8 has so much low end torque you don't need a strong 1st gear.

however from a roll it's a little bit different story. At 40mph, you'll be in 2nd gear at around 4100 rpms. He'll be in 1st gear at 5100 rpms. He'll be higher up in the powerband making a lot more power and your 2nd gear will actually be roughly 20% weaker than the C6's 1st gear when you mulitply it all out thru the final drive. But as soon as he shifts and you get higher up thru your 2nd gear, you'll catch up, then eventually pass him. You will have to shift fast though

When the C6 shifts, its rpms drop to 4500 almost everytime aside from shifting into 6th gear. Though when you shift, you'll be at around 4600, then roughly 5200 after that, and making better use of your powerband because the Z's gear ratios are closer together than the C6

so I think he'll get the jump, then you'll slowly start walking him until you're about 3-6 lengths ahead of him at 140mph. The Z's gearing LOVES 100+mph and maxes out at 187mph. Where the C6's gearing is stretched out to cover what would be 266mph, though it does have a little less shifting, but like I said, when it does shift, the rpms drop to 4500 when you'll be at 5200 (from 4th gear onward) if you shift at redline. However the C6 is more aerodynamic and it's engine is a monster at higher speeds

here's a rough dynograph of a C6 vs what your TN dyno probably looks like in dynojet numbers

thick is TN
lighter graph is C6


this should be an interesting race though that really tests the abilities of the cars and puts less attention on the launch technique and tire grip at launch

 

You forgot about the 400lb block he is pulling, wind factor, and C6 has a 195mph+ top end. C6 gearing is better meaning he does not have to shift as much as the Z does. He could take 4th gear to 130mph if he wanted.
