specs for wing on FED

[wideopen231]

Anyone know of spec for wing on FED. I looked thru heritage series rules on NHRA site found nothing,does not mean I did not overlook it. Heck happens all the time with me. I know what I want.Cheaper air foil tubing would be great.Man 14 bucks a foot was what i use to pay though that was high.Found 2 site in mid 20's price wise.Thats about 140 per side.

   Want to build it mounted lower on chassis and leaned back some with very low attack angle. I did mock up with cheap tubing and it lokks bada-- IMO and since its my car that  overrides all others.If going to build I would rather make it legal if possible.

Rear wings are tabo on FED's  = side canards only. Front wing is limited as per rules.

SO Van are you trying to talk me out of wing or into it?   Going against the grain(except in my wood projects) as pretty much always been my way.

[Van]

I don't have anything against a rear wing on a FED, just answered your question. I just built and installed one on my car, on the front. If you do a rear wing and want to run a heritage race, i would think that you could just remove it.

X2, just set it up so the struts are pinned in and just remove the pins to remove the wing

Been thinking on setting it up so that the top where it covers the roll cage has two air vents .Then running the  rods that go from front of strut to the chassis thru them,if not for brain fart I would know the name of it. 

  Next trick will be getting the main strut thru lower section of body. Maybe above lower wheelie bar mounts.Im not crazy about fastening to top of cage. Trying to look at safety also in case of. Maybe after body work is mounted I will get some brain storm for mounting it.

  Yea the traditionalist are going to hate me. Oh well. To me racing is look like buildimg custom Harley do what you like. Just have few rules with racecar and non with Harley.Some will think awsome some will think POS. Plus theme is NEWSTALGIA. 4 bolts and no wing.

  Getting the drawing board out right after coffee.

Just playing  with idea of how to mount wing.



 The angles are working for me but still figuring on how to get chute body to work with it. In rendering I posted under give me your opion post.It was mounter to top of cage,not crazy about that incase driver gets stupid and flips it over or something of that nature.

A rear wing on a FED  of any real downforce MUST be mounted in front of the rear axle, mid way between motor plate and rear axle would be best. With wing behind the axle you would need a major amount of wing downforce at the front axle to counter the cantilever effect. If you mount it behind you, I suggest you keep it small & at a somewhat neutral angle.

Are you serious ? A wing behind the driver on a FED?

Really not that bad of an idea . I would like to hear what Roo's thought's would be about this . I don't think it would have that much of an effect on the front of the car but I do think it would make the car more stable at speed.

[GlennLever]

I don't know, but I don't think you ever want to take weight of the front and with the wing in back of the rear wheels it does not seem the right thing to do?

[wideopen231]

I figure the front canards will off set the wing.Plus remember wing angle effect amount of down force.A well designe wing can be run at negative angle and still provide down force.I think the key is how much down force you have. With my motor being 51" out I think it will be benifical.If not It only cost me the price of the airfoil tubing and thats enough. I have templet I got from wing off my TA/D and it came from fellow I met in Gainsville who worked for this little company NASA you may have heard of it.

     I spent cpl hours talking with him and got ton of info.Plus he was buuilding wings for guys like Jay Payne at the time.I'm going to reduce the size some since this car is nowhere near 3000 hp,lucky if getting much pass 1000 before nitrous.

  The more I play with this setup thye more I like it.Kind of ties the nostalgia to the new. If not using name Starr Rider I will use the Newstalgia which was idea from start of wanting a modernized FED when I drew first sketchs. Man that issue of Drag Racer that had blue and yellow Jr fueler I think little huslter has cost me lot more then cover price.

  Hey Glen Im sure few thought the first guy to put a blower on dagster engine was crazy too.

[Van]

YUP  them NASA guys got's those Aliens that they been keepn alive for years, (area 51) making them tell all kinds of space secrets. Your car is gunna fly.

looks like 4 aliens escaped and are living in washington at 1600 pennsylvania ave. Suppose to fly thats why it has parachute.

 with battery 35 lbs. fuel tanke 4.5 gallon 36 lbs full fire bottle 5 lbs and nitrous bottle 18-23 lbs and all mounted as far foward as possible.Then Im sitting more foward with the high chair postion and rear end is almost tucked under my rear and the motor being 51" out I think there is lot more than normal weight on front. I will be weighing it before hitting the track to check how much front and rear weight.

  Starting with 480 sq in of wing and at -2 degrees and move up till I get to +4* or I feel it needs to be moved back. Sheets for this wing design show 163 lbs down force at 200 mph.Plus 90% of runs will be 1/8 and only 150 to 160 mph which is around 104 lbs down force.Plus front canards have to provide some down force.

  Worst case I pull wing and mount the canrds in front of rear wheels or better yet the aerodynamic effects I have designed that also add down force.
