Cruising around looking for trouble but not really expecting much, out of the blue a black C6/C5(couldn't tell right away) passed me, I thought for a second and then flipped around and chased him. I pull along side of him and he quickly shoots forward and puts on his signal to turn into a residential area, so I followed expecting the usual vette owner's attitude.

At his house a block ahead he gets out of the car and is laughing, so I ask him, "want to race just for fun?"
He replies, "you don't stand a chance in this, how about my other vette." I look over where he is pointing and its a C4, so I say "ok but I dont think it will be close". He says he has mods on it so I figured what the hell, not like I had anyone else to run.

GTP v C4:
We get out on the freeway and he floors it right away, so I do the same and quickly overtake his jump and run by him. So we turn around heading back towards his house, he is yelling out the window, I figure he is upset or something, but instead he says, "Do you want to run the other one?" I said "hell yeah!":grinyes:

GTP v C6 Z51 Manual:
I new he would hit it right away this time so I was more prepared and when he did floor it, I pulled immedeatly from 20mph to about 80-85mph. Which was when he appeared to slow down a little. At that moment I then ran out of fuel:mad:, LOL, so while I filled up he was telling me he missed 3rd at 85mph and wanted to race again.
This time on the way back we went from about 60mph and were dead even. When we shut down at 125-130mph, I was quarter-half a car ahead. What a race, I thanked the guy out the window and in doing so I missed his turn to go back to his house. When I looked back I saw a cop pulling him over.:mad:

Sucks, I hope the cop was leniant. On the other hand it is nice to know I can pull a C6 up top with 91pump/catback+seats in/2.8pulley(13psi) . I knew it would be close but I did not expect to pull on him from 100-130mph.

What a freaking rush, I wish I had a mounted camera, I wish I had a mounted camera, I wish I had a mounted camera...

Great story but it totally blows that he was pulled over in the end.

why didn't you think you could take him? You have an 11 sec. car. You should have no fear of those C6's what-so-ever.

I trap 114mph with 2lbs more boost, slicks, 94octane, 100lbs less weight, and 3* more timing advance. With all those factors combined I figured I only would trap 111-112 and run 12.3-12.6 in my "street setup".

Dont the C6s (manual/hardtop) run about:
0-60: 4.1-4.3s
1/4: 12.5-12.7@110-113mph

With higher octane, more boost, less weight, better tires I know I would smoke him. :evillol:

I have ran a few at the track and I had 12.1-12.3s@114-115 to their 12.7-13.1@110-112.

Next up is the C5 Z06, some day...

Skip all that nonsense, how about just rear wheel drive ;) It could be done, heh.


Nice kills on the vettes Jeff.

Ever since I joined this forum, I have been afraid of GTP's because of you Jeff lol. Do you have a list of your mods anywhere? I'm very curious to know what the hell you did to that thing! Oh yeah and obviously great kills, funny that you ran out of gas lol!

its amazing how fst that car is. my buddy has one, its stock, he lets me tear it up every once in awhile. but to know that you have the same car running those times is like whoa.

i think you might win best sleeper next year

Damn....we would be a HELL of a race. Would be fun.

Nice kill!!! I have wanted to catch a C6. Not going to happen with the stock motor though.

that is totally bad ass. those c6's are beast. any car that traps 114mph is a beast in my books, but yeah lets just hope for the better and hope that the cop didn't see you guys doing 130mph.

That kinda counteracts your sig. :icon16:

The "Boost is Better" stuff makes me laugh when I see a post with you saying ANYTHING trapping 114 is a beast. I don't have boost, and should be trapping around 113-114 off this mountain. I don't care about turbo lag....I have torque. :tongue:

hey luos, just curious, wut has ur car run as far as et's? if youve run it. im wonderin cuz i got a silverado that i want an LS1 in BAD. and if u cant take the C6 stock who cares? u got a back seat. sort of lol. and as far as makin the rear wheel horsepower a 350Z does, y dont u tell TATII wut the trans ams and SS's run at the wheels stock hahaha. its amazing that the importance of torque is lost on so many expert street racers. if i cant get wut i want from the truck then an F body is next. cryin shame chevy gave up on em.

I was really just playing around with my post.
Corrected ET's....12.8 at 113.
Actual ET....14.0 at 105.2.
I use NHRA correction factors for actual altitude, not actual DA. Most of the time I race, the DA is over 6500. The tracks altitude is 5860 feet. Eats a ton of power from an N/A car.

Nice run, hadn't heard much from you lately, glad to see you are still running strong and blowing the doors off the fast and expensive. Keep it up!

i think he can argue that torque is not as important as horsepower when he does highway racing (which is what tat does, correct me if i'm wrong).

SOme interesting comparisons:(I used 330whp to account for running 2#s less boost)

C6 Z51
-------------------------
race weight: 3250lbs
drive: RWD
whp: ~340whp
Torquecurve: flat to ~400lbs

My GTP
-------------------------
race weight: ~3250lbs
drive: FWD
whp: ~330whp
Torquecurve: steep decline from ~400lbs

nice kills, are you done modding your car? Or are you going to do some more? Also, how is your car as a daily driver? Or do you have another daily driver? L67 > ls2 :grinyes: ! (I would kill for a 05 GTO though)
