09 Sedan vs Audi R8
 

Had a little fun with a Audi R8 the other day on the freeway. He came flying up an on-ramp pretty quickly so I was guessing he might want to play around. He moved over to the fast lane right in front of me, so I moved in a little closer and he started to take off. I took off just after I noticed and thought to myself I was staying in pretty good.

He had to hit the brakes in traffic and moved over to the center lane, so I rolled up next to him and gave him a thumbs up. He smiled, then started to take off again but I was more ready this time. He hit it first and I down shifted quickly to 3rd and took off too. He had a decent jump but I made up the 1/2 car length jump he got on me while in 3rd, and shifting into 4th I pulled a little more and had a little more than 1/2 car length on him when we hit the brakes I guess around 115.

I am sure it was just the 8 cylinder (looked it up online), but those are 420hp and trap around 110-112 typically. I was surprised but not astonished that the Cobalt ran that well. I have had it about 6-7 months now and it has felt strong. My last car was a 320whp 2500lb MR2 and this car still felt pretty fast. I am stock except a drop in K&N, ZZP IC, and self tuned on HPT (93 octane tune at 23-24 psi peak).

He would have killed me from a dig with all wheel drive, but he weighs a good 500 lbs more, so the 420hp was not quite enough for him (R8 is heavier than I thought when I looked it up, at 3500lbs or so). But his eyes were pretty big when I pulled a bit in front on the highway. Chalk up another win for the Balt camp!

Crazy I had the same exact thing happen to me tonight! We made 2 pulls from 2nd, both of which he jumped, he was just as surprised, cool dude too. I was too focused on the road but it had to be a difference of at least a length or two. FWIW I'm on E, but definitely happy with the cobalt!

Nice

Nice win. Would love E also, but not convenient for me. I am surprised how well this car runs for 143k miles and still on the original clutch! Previous owner did most of it on the highway. I do have to ramp carfefully and probably give up 20-25wtq in the mid range.

I have thought about meth inject which worked wonders on my MR2. Just need to figure out how to have the tune run with/without it easily without reloading the tune for each one separately. n

Glad to hear the car is still running strong.

Define not convenient, running an e47 blend will net you slightly lower fuel mileage but if it's a 10-15min drive out of your way totally worth it.

E 47 is so worth that short of a drive.

It is thats how short it is for me!

When I first logged a 4.2 second 60-100 (I'm @5,400 feet) a few years back, I was looking for a reference point of whether that was fast. The one I liked the best was the Audi R8 V10, which takes 4.8 seconds. AT SEA LEVEL! :lol:

I'm guessing you are in the 3's now.

3's aren't feasible at our altitude, at least not with the 6758...
At sea level people with my mods have ran 3.5's :)
