Does it work?

[RallySnake]

The front spoiler on the FFR Spec Racer looks pretty good. It's not too big or obtrusive. If painted a contrasting color (black) I think I could live with it. The big question is, does it work?

My Arntz nose starts lifting big time about 160. I don't have the guts to find out if the front wheels will lift off but I think they will because the car is still pulling hard in fourth gear at 4,500 RPM.

Can anyone give a review of the spoiler's performance?

Paul:

Hate to burst your bubble, but unless you are running a 2.5 to 1 ratio, your speedo is way off. To run 145 @ 4,500 rpm with a four speed and a 26.8 inch tall tire , you would need a 2.46 gear.

Well, at least SOMEBODY replyed!

You're right Jeff, I musta been in fifth gear. Try the calcs with 4,500 RPM, Hoosier 275/60/15 rears at 28.0 inches diameter, a 3.31 rear end and .68 overdrive. That's the ticket!

So what about the spoiler?

Thats better, how about 166 mph. What kind of hp are you making?

Thank you jeff.. You saved me from getting out my calculator.. I bet he is pulling really hard at 4500.. but I suspect he is going closer to 90 at 1:1..
