Anyone considered (and even better done something about) aerodynamics as a mechanism of car tuning ? make the car more slippery through the air / reduce lift / promote downforce rather than engine tuning to go faster ? Are experimenting presently with my Ibiza - have a sprint in 2 weeks with a couple of speed traps so we will see if it makes any difference Love to hear what people have tried Cheers Rob
Blanking off as much of the grille area as possible , duct taping the panel gaps , running the car as low as possible with the nose down slightly , flat sided wheels , all things that help a wee bit . What speed do you expect to reach?
been contemplating flat flooring the front and rear of the mk1. big concern is the potential high temps due to exhaust not getting airflow.
I normally go through speed trap at 117 on a windy day and 121-123 on a still day - we will see if the mods have done anything - pics soon
steved has a little ply wood undertray at the bottom of his bigbumper mk2, I think he said it felt like it made a small difference. Not really massive areodynamic changes thou.
Rob you reminded me about t thread I read on sxoc ages ago where people were making their own airdams and undertrays. Went searching there for an hour but couldn't find the exact thread. Did find some info though, links below... http://nismo.q45.org/airdamstech.pdf http://autospeed.com/cms/A_108674/article.html - Some info on wool tuft aero testing. Although this is for a rear diff section of a Nissan 200, the same principal would apply using louvers to relieve pressure and direct flow. Could also do something similar to a POrsche 911 T to the rear qtr panels with louvers to relieve pressure in the rear arches. - Would help with brake cooling again.
top stuff phil - thats the kind of stuff I was thinking about - are currently fitting front end items but winter project will be to flat floor the entire car - maybe with honeycomb ali sandwich if my source comes through with the goods......
ABS sheet would be good to work with, easily procesed/formed, hard wearing, light, strong and cheap. You wouldn't even need a high grade, reprocessed would do.
It's basically the same stuff car bumpers and dashs are made from. We supply it in 2440x1220x3mm sheets. circa 30+vat. Thats for A3100 grade, matt/pinseal. Don't have any reprocessed in stock atm. Pm me if you want some datasheets or info on it.
Rob remember Tramp's bonnet with the raised rear section, effectively changing the screen angle some good books available on this clickclickawahwah
Was it raised to change the aerodynamics or to aid in letting hot air out? Wouldn't you get turbulant air at the back of the bonnet before it goes over the screen?
