Just throwing my salt on the pile...
I'm running a 1FS catless and an X-mod.
The 1FS downpipe had 2 good welds on the entire part. They were all good looking welds, just tremendous lack of fusion. I had to redo all of the rest of them. It's fine now. $350 and you get what you pay for.
The...
Welcome to the forum, buddy.
A lot of what you asked has been posted numerous times before so luckily, there's a lot of discussions on those matters. The advice to search the forum is actually a decent response in this case.
As for more power, I'm in the camp of learn the car first. These...
Any time you want to check setup, you need to eliminate as many variables as possible.
-You need a level surface. If you don't have one, get something to shim/crib until you have 4 level pads under the car. A $50 line laser from Home Depot and a wide base square is priceless for this. Make sure...
There is a relationship between endplate height, downforce, and chord width. I know there is a point of diminishing return with excessive height though.
I personally like either the basic square endplate design or a fully sculpted endplate but that's just me.
Someone mentioned a DRS wing a while back on a different post. There seemed to be a tiny bit of interest but the primary conclusion was that no one would buy it. Either way, I'd still love to make one but I have zero interest in whether it would sell or not. My world is in prototyping and...
I could see doing DRS with the whole wing, but a DRS flap on a wing with that much curvature around the vertical axis?
That may actually be new territory entirely. If not, I'm sure that the only people that may have gone down that road with any sort of success would be some engineer that was...
I distinctly remember one of the aero guys from an old team that I was on saying that CFD is great for when you want to predict the direction that a change is going to actually make, but it isn't so good for finding the true magnitude of that change. As long as your inputs are decent then I'd...
3mm isn't a bad choice. I'd call it good tbh. It'll last.
As for the sleeves and barrels, I'd look at using both. The countersunk bolt will hold it's piece in place but the slack between the bolt and the bolt hole on the other parts isn't a matter of whether it will or won't wear, but rather...
A 3mm thick shell is close to what I've seen for limitless budget stuff that has to survive Sebring (Mind the Bumps) at over 200mph. The sun will get to it before anything else at 3mm thick.
8mm thick 6061 would be fine as long as it's 6061-T6. It's probably never going bend much but you do...
I'll be honest, I know enough about CFD to be able to say that @i3igpete knows more about putting CFD to work than I do (post #81). What I know about CFD is mostly just disconnected islands of information and some intuition. I can look at something and get a ballpark idea of what's going on...
Turns out I did NOT get around to jigging, mock up, and fab by what I said would be tomorrow. Either way...
I'm fully aware that this is long winded, but there isn't much of a consolidated source of some of this information online.
Jigging can honestly really simple. There isn't really a main...
