    ...recommended a 30 amp relay for power and a 20 amp fuse after that to protect the ECU. Reference your earlier question about the GT-500 wing, the center section is "scooped" to change the angle of incidence (and consequently, the angle of attack) for the center section of the wing where the...

    I'll ask the same question to you - I looked at the GTC-500 and wondered why they create a scoop in the center of the wing. To my novice eyes, that would create high pressure under the wing - would it be better to go taller and use a flat wing? on that same issue, should I run braces from the...

    Stainless, no purge. I only purge where the stainless is going to heat cycle. That said, I'm beyond zealous about clean surfaces. I'm sure somewhere in that cesspool is good information - but it would take less time to make all the mistakes and fix them then it would to deep dive there...

    If you go to the APR Performance website and drill down through the products (wings) you can get to the drag/downforce tables. Her is an example for the GT-1000, dual element wing: https://aprperformance.com/racing-product/gt-1000-dual-element-adjustable-wing/ That is their highest downforce...

    This is pretty old, hence the paperback sells for under 20$. Theory of Wing Sections: Including a Summary of Airfoil Data Book by Albert Edward Von Doenhoff and Ira Abbott The manufacturer data mfain refers to above would be better and account for the angle of attack variation in the wing...

    ...radius. Build in clearance for full tire motion at full compression. Plan for aero - include strong, accessible places to bolt things like wings and splitters, and try to keep things from hanging down under the car that would keep you from having a clean, flat belly pan that does wonders...

    They want it wired directly to the battery. No fuse... I'm kind of not following their advice because I wired it to remote terminals. I'll say this for certain, not putting some kind of fuse or disconnect in that line goes against absolutely everything I've ever been taught, seen or heard...

    ...I've got some other pics but will need to do a search. Meanwhile, here is a Successful Camaro from a few years back: You've already got the wing! A couple of D&Ds from pintrest: I'd like to find an overhead of his radiator setup. Bet it is a lot like others we've seen before. They are...

    ...is the only car that was able to produce negative lift numbers." Sounds like a sloped back window would significantly help whatever spoiler or wing you decide to use on the rear. (Like the old Monte Carlo NASCAR back window). Would be fairly easy to build and could even be made removable...

    ...These are the classes that lie "outside" the normal structured classes. These are the ones where you can "run-what-you-brung" and often have Wings & Things openly permitted. SPO in SCCA and SU in NASA are the ones. These tend to open up the opportunity mix I am looking for. Time Trials...

    I'm going to put a wing on this car... what would you put and why?

    ...It handled very well, despite the hp handicap, it did well. That said, it could be better. I need to put more of an angle of attack in the wing - when I'm hard on the brakes, having downforce would really be nice. The problem was it was tailhappy (oversteer).... which is an odd problem for...

    ...a positive.... and honestly, I'm tired of it. people with tiny feet don't get it, but the pedals are pretty annoying to anyone else. a bit more space for feet - and the benefit of not catching your foot under the brake pedal power window switch fixed and the rest of the wing parts arrived

    ...downforce at the expense of some drag. Any downforce would be over the rear end and help eliminate any nose lift that might come from a wing further aft. Potentially a net gain, as you might be able to run a smaller splitter. A problem with the Corvette (and most vehicles) is the roof...

    Good cover Pappy. Your point is clear, else the Wright brothers and all WWI aircraft could have never flown with fabric wings! The total downforce is over the entire surface, wing, splitter, canard, tunnels, belly pan, etc. I am concerned regarding the support structure for the...

    ...6" from the outside because the space behind the rear window is a wind-reversing mess. What is helpful from above is the advice of getting the wing in clean air - in that vein, I note some wings have a raised, center portion, my initial impression is that would create high pressure under the...

    This car is for sale, and some spent some money ( blower etc. ). But I think the wing is backwards. Good price actually.
