I guess you missed the sarcasm. My bad, I should have realized it was a little over your head. He didn't actually give a lecture before the wheelie, besides how scared of the car he was, I was just commenting on how rediculous the movie is, and how you all seem to live by it. If you stop watching it, and actually go out and learn something, you might be a little better off. You get it now?

BTW, what was up with loosing the floor pan in the Eclipse when the manifold pressure got too high?

Dude. It's a movie. Get a life.

To respond to your other foolish posts:

1.) No one was bench racing here. That is when someone claims they can beat you with such and such mods without proof of time slips or video or actual track head-to-head.

2.) You are plain wrong about the compression and the fuel requirements. Modern engines designed for natural aspiration are runing 9.8 on the low end and up to 10.5:1 on the high end. 20 years ago 8.8:1 was considered low and high was considered 9.5 or 10:1 Now days 11:1 is considered high and 9.7 is considered low. Times change. Cylinder head design improves, electronics improve, even fuel composition is altered.

3.) You came on a contour board, a car that runs 9.7:1 stock compression from 1995 and runs on 87 octane with no issues, and claimed we needed race gas at 9.8. Even to imply that we needed to "look at it" at 9.8 is just showing you are ignorant of new engine design. Hell its old news now, this engine is TEN YEARS OLD! THe SVT motors are 10:1 and 10.2:1 stock. They recommend 91 octane but it will run with 87 by pulling back timing as necessary.

4.) My car runs "massive boost" at 6-10psi because I have a 10:1 compression ratio motor. So far I have run 12psi on 93 octane and no problems. For this motor that is massive boost. That 6psi I pulled 300 Horsepower at the wheels in that weather. For 8.5psi I pulled 328 Horespower at the wheels. All on 91 and 93 octane respectively. THe dyno graphs are posted on my site.
Oh, and 1/4 mile times are also posted. As I stated, I OWN3D your ass on that one.

5.) I could post a dyno with A/F data showing 14:1 at the tailpipe on 92 octane and no issues. In fact, it was hosted long ago by someone and may still be up. I'm not going to waste my time because the boosted graphs on 91 octane are sufficient to prove the point.

6.) You sir deserve a for you foolish posts. You are a troll. I wouldn't waste my time on you alone, but this topic may come up again and next time I want to see people to tell you to search.
Get educated by reading instead of watching the fast and the furious for you lectures. Grasshopper.
