Replica Drivers

Just a quick question for those who drive BoB rteplicas or even Yellow Interceptor Replicas..








In your opinion, Gentlemen...








Do the benefits in downforce of the roof spoiler outweigh it's liabilities in drag at higher speeds?





Having driven cars with similar boot spoilers (Same cars with & without) I'd say that the added stability of the rear spoiler is definately worth the trade-offs from the drag, but I'm curious about the roof spoiler.

Since I only have one Aussie Falcon and it has the Max kit on it,I have nothing to compare it against.At least until my other coupe gets here.But I have not noticed any problems with the roof spoiler,other then worrying if it will tear off at high speeds(120mph+).Cheers,Bill

Hi..


Hmm.... Do doubt that the roof spoiler will reduce the top end a bit, I have driven a quite a lot at high speed in the replica. So I have noticed and can comment on some things I have experienced.


The Monza nose is excellent, the front of the car feels way better than my standard body road going coupe. The replica sits flatter, and feels more stable.


Because I also drove my own replica with the roof spoiler but with out the monza nose I could notice the input of the monza nose immediately it went on.


I have never had my road going coupe feel as stable and as flat at high speed (125 MPH plus) as a replica.


So something is working.


As to the stability of the roof spoiler I pulled this text out of a the "pilgrimage" story on my website.


" perhaps it was because of that roof spoiler, perhaps it was just a change in road surface I shall never know) but the car was super stable".

At 150 -160 MPH in a replica you feel very secure, the car does not "float". However the back end will still "step out" and gyrate a bit if the car is unbalanced in a high speed corner, (unbalanced = hitting a bump in the road) it is predictable though and all coupes do it. But that word "float" is a key word. The combination of the monza nose and the roof spoiler must be reducing the air flow under the car a bit. So (along with good shocks and springs) the cars are stable. The raised rear suspension will always be a bit of a worry, but the spoilers must be counteracting that to a large extent.


Even so the replica with its 1970's suspension is a straight line weapon, and I think that the trade of a few MPH is worth the stability you gain. In fact the stability might allow the car to travel at a higher real speed because you can actually keep it on the road.[/font]

*wonders how a Monza nose would look on a Javelin.





(Actually, I "photo-bodged" a Monza nosed Black Javelin a while back. Looked... Interesting to say the least)
