Congratulations for your awesome work. But unfortunately you make a mistake in the exhaust ignition explosion order of the VW Aircoold engines, that the correct is 1-4-3-2, and not as the design of your exhaust order that is 1-3-4-2. Hope this information help you to improve your performance.
Pop the collector off and that's what I've got. But there is a benefit to the collector and muffler, they do help the engine produce more power. I've had the collector and muffler fall off in another car I was racing and the car feels like it's down a cylinder.
Engine Masters did a neat video where they dyno'd an engine before and after bashing the headers with a hammer (like what someone might do to make clearance in the engine bay). The car actually gained negligible power. Based on that info, I would speculate a larger bead of filler on the inside of your exhaust wouldn't affect the power at all. My $0.02.
ThomsenMotorsport that's a pretty wicked car though man! Is that what you specialized in was chassis tuning? How many calculations have you done that we don't get to see?
well i appreciate the sensitivity toward dealing with the harmonics of the flow - but (were it allowed) wouldn't a FAR SHORTER pipe help you generate much more horsepower?
Most likely, while I'm aware of the effect I didn't design for it, I just worked with the previous cars lengths as a guide. I had too much on my plate at the time to learn about it and optimize my runner lengths.
термоленту лучше намочить в воде, прежде чем наматывать, она тогда лучше обжимается. а если потом покрасить, то с нее не будут сыпаться волокна, в процессе эксплуатации.
I just used the same length as the crashed donor car I had. I'll be honest, I'm not across the engine at all, it's not something that really interests me. If I need improvements I'll take it to someone and get their advice.
Are you referring to a gasket? I've not used one since neither the car that I used to race nor the donor car that I bought to build this one used gaskets between the engine head and exhaust flange, frankly I just assumed it wasn't typical to use one because of that. It seems to be sealing without a gasket now that the flanges have been replaced so I'm not worried.
The reason is related to the CAMS Specification of Automobiles for 1st category cars (of which Formula Vee is one), under section 2 General Requirements item (vi) which states the car must be fitted with : "Exhaust pipes, the orifices of which, when directed horizontally to the rear, must be between 300mm and 600mm above the ground, and may not protrude by more than 250mm beyond the rearmost portion of the car." If I exhausted it horizontally it would have a discharge below 300mm above the ground so would be illegal.
Nice work, any closeups of the welds!? :D
Thanks, I'm afraid I didn't think to get any, no.
No worries, have subscribed, look forward to seeing where this goes :)

Amazing.
Nice project bro! But don't you think would have looked beautiful to have 4 exhaust Pagani style exhaust?!?

Probably right. I don't know enough about engines to say.

yes sure - thanks for your answer
i'm really enjoying watching these BTW - thank you for sharing
Thanks, good to hear.

Which CAD modeling software do you use?
Solidworks
Can you make a video on CFD analysis u can start with bit of basics
How much did a whole system like that cost stainless steel wise
what formula you have used to decide length of pipe
I just used the same length as the crashed donor car I had. I'll be honest, I'm not across the engine at all, it's not something that really interests me. If I need improvements I'll take it to someone and get their advice.
ThomsenMotorsport thanks
Shouldn't you have used a flex to mitigate the flanges deforming?

Well, I meant a flex joint in the pipes, to allow for movement. I was unable to edit the first comment to clarify this because of an error on TH-cam.
Why is the back of the exhaust pointed upwards? Thanks

ThomsenMotorsport isn't that a problem wen it rains?
Hi mate, did you do any research regarding pipe diameter or did you use the same diameter as the original pipes? Thanks
No I just reused the previous pipe size, same as what everyone runs in this category.
ThomsenMotorsport is that 1 3/8 if you don't mind me asking? Cheers
1.5" with 1.6mm wall thickness.
Wouldn't it be better to run a 4 into 2 pipes seems it's a boxer engine?
wait, what engine is that car from?!
The engine is from a VW Beetle.
oh nice, but like those are pretty low horsepower engines, do the rules of this series allow to modify the engine?
