Thread: Bone stock 2008 Grand Prix (base) 1/4 mile E.T. & MPH ?!?

My wife bought a 2008 Grand Prix (base) a couple months ago with 28,000 miles on it. It now has 34,000 miles on it. Anyways it is bone stock with synthetic 5w-30 oil and I was wondering what the 1/4 mile (drag race) E.Ts & MPH were from the factory?!?

I saw a gt running 16-18 at the track. That was a 97-03 style tho.

maybe 14s if you know how to drive, but i doubt it.

14's supercharged...High 15's low 16's N/A with a good driver.

Nice line of Mopars you own there, I'm a Mopar fan myself.

And i'm with bluegtp91 as far as times go...

Thanks, I have quite a few Mopars.

I was thinking low 16's, but I didn't know and I couldn't seem to find any performance tests anywhere online.

Only one way to find out...take it to the track

Very true.
The downside to that is my closest track is 4 hours away and it's been closed for a month already.
Besides when I go there I usually bring one of my 'faster' cars, not that any of my cars are truely 'fast'.

Whats that Dart run? Looks like fun!

I got soooooo close into buying a 72 Dart w/ a big block about 7-8 years ago, kinda regret missing out on that one, along with many others, LOL. I'd have about 200 cars if I took home everyone I found! LOL.

Yeah that's my problem. I have more cars than some of the salvage yards around here.


That day it only ran a 14.00 @ 99 mph but it threw the belt right off the start. I only got the pone run in and then the event got concelled (rained out) and of course it was the last event of the year!





I do have a healthy big block Dart Sport (original 340 3-speed car I'm currently putting together), but this 1972 Dart is a small block. Though it is supercharged so that helps (when the belt stays on).

Nice belt! LOL Low 14s with no belt, wonder what it would of run with the belt. What compression ratio are you running? What kinda heads/cam? Just curious.

Showing/telling me about these damn Mopars makes me wish I was 16 wrenching on my buddys 72 Road Runner, good times... Lots of trouble....

Wow, I didn't realized I incorrectly spelled so many things in that post.

Anyways, I was really curious too. It runs strong when the belt is on and the blower is working.
The engine is the most basic engine we have actually.
It started as a 53,xxx mile 1974 360 that we purchased an entire truck for (only $200.00). pulled the engine/transmission and put it right in the Dart. We supercharged it and was running it like that until about 3 weeks before we were heading down to the track when our buddy dropped off some extra parts he had (because he just upgraded his 318 again, don't ask!) He brought us a used camshaft which has the 340 specs (.429" lift) with a 114 degree centerline which we wanted for the blower. He also gave us his old double row roller timing set, and a lifter/spring combo. Basically it is built as a high performance 340 would have been from Mopar back in the day, just with the smaller bore/longer stroke of the 360. The compression is the stock 8.5:1. The heads are stock as well. In fact other the the above parts the engine had never been opened up. The supercharger pulley is a 3" and the crank pulley is a 6.75". The carburetor was a standard Holeey 750 cfm double pumper with mechanical secondaries that wasn't really properly set-up for a supercharged application.

Looks like over the winter we'll be building our recently aquired 1968 Dodge Coronet coupe for next year with supercharged big block power!

Nice Coronet! Looks to be real straight and clean! Nice find there...

Yes, it's extremely Straight & clean!
It is a rust free New Mexico car that I bought this past July (2009) at the Iola, WI car show and swap meet for only $6,100.00!
What a deal.
When I purchased it it was equip'd as seen in the photos (were taken 2 days after we got it home).
For the purchase price here is what was on the car:
Fresh 1968 high performance 440 cubic inch engine (real HP2 stamped block)backed by an A-883 heavy duty 4-speed manual transmission (with 11" Hayes lightweight flywheel & clutch combo). The engine has a Holley 650 cfm dual feed 4-bbl. carburetor on top of an aluminum Offenhauser (360 degree) single 4-bbl. intake manifold. It also has headers, has been converted to electronic ignition via a brand new Mopar Performance kit (ECU, distributor, harness, ...), Accell 'Super Coil' performance coil, Mallory 'Super Wires' performance ignition wire set, Moroso chrome valve covers (same shape as the factory pieces), and Moroso chrome 14-inch drop base air cleaner.
A few other items I noticed immediately was the mint 1968 Super Bee power buldge hood, the glass/chrome trim is all in great shape, and it has 15x7" American Racing aluminum slotted mag wheels with three of the four center caps present!
The mechanical fuel pump, inline fuel filter, and alternator were all changed recently as well.
I love the car!!!
It ran great & drove beautiful as purcahsed as well.
It was originally a base model Coronet with a slant six and a column shifted 3-speed manual transmission (3 on the tree). The only 4 options on the car (originally) were AM radio, chrome B-pillar (coupe body only), chrome along the tops of the doors, and the chrome along the bottom of the car.

Since these photos I've added some more go fast goodies under the hood, smaller tires up front and lowered the front of the car ~4 inches.
I've also started to clean up the body and I'm getting ready to paint under the hood and maybe spray the car next spring...

I love to see more pics of that Coronet, at least progress photos of it. Feel free to PM/E-mail me anytime man!

Gotta love southern muscle cars. Wish i could get lucky enough to find something like that. My parents 1973 Cuda was a rust bucket, it lived in Omaha from 73-81...

Wow, that seems smoking fast for a stock Grand Prix!

It's cool, at least it was pertinent to the topic.
Although the time he reported is sketchy at best.
I thought maybe he had some secrets on how to get a stock GP to run a little quicker poor/unofficial timing system and a homemade drag strip seemed to be his strategy.

Here is the PM I received from him:
