no one local can do mandrel bends, I could weld all my charge piping but I'd like seamless better. So how much will the crush bends effect it? This would be for 2.5" piping either way on an EF w/ D16.

If it matters that much.. why not call the towns around you?

Just do the DIY JC Whitney intercooler piping. If you want the "seamless" look grind down your welds, bondo the piping and get it powder coated. That's how the Harley guys do it

 

nearest place that does it is 100 miles away, and i'd have to trailer my car.

bondo and **** would work, thats a hell of alot of labor though. i'll think about it...

 

man just do what you know is right,then everytime you pop your hood you don't have to worry about someone talkin ****...plus you know the mandrel bends will be better for the car,it's never good to resrict air with forced induction. Good luck no matter what you do

 

Crush bend pipes will cause turbulance and disrupt flow..go for mandrel bend pipes.

Good things come to those who wait

 

my pipes were like pinch bent(not mandrel but not krinkled crush bent either, see pic below). i had a 5.8 psi wastegate spring and i would boost a solid 6 psi out of it(also with johnnyracecar 5" intercooler), so i didnt experience any pressure drop out of it. if i were doing a high horsepower setup id probably use bends from kteller.com, but for low boost i think any bend but crincle bends should do fine.



edit: ive been up for a long long time, so please excuse the poor spelling

yeah if you're running like 8psi or less.. piping aint gonna matter much.

yes 8psi makes a huge difference on our motors,
but it is still just 8psi of pressure.

remember most stock turbo cars run around 9-11psi stock,
and they come with those tiny intercoolers and goofy plastic charge lines..

i'd say, if its a custom kit, and low boost.. and you arent going to upgrade in the future WHILE reusing the same piping(ykno in most cases if you go better you'd probly have to change the piping out anyways), then just do whats cheapest.

spend the money on things to make it a safe/reliable setup.

IMHO, pressure is not all that important with charge-pipe-designs. What's really important is that the pipes will, with as little as possible restriction, flow those lbs/min of air as his engine requires. This also obviously means, as little as possible pressure drop over the pipes.

 

I offer custom intercooler fabrication if you are interested.

Here is a kit i did for an EG running the sidewinder manifold.



All piping comes with the heavy duty blue silicone couplers, t-bolt clamps, bead welded ends to prevent pipes from blowing off, BOV flange, and the option of Mild steel (aluminized), aluminum, or stainless steel piping for 2.25 or 2.5" applications.

Looks good I think and comes with what you need.

Dude, wash your feet.

 

Foot sold seperately

 

LOL!

 

How much do you charge for your custom pipes?

You can't bondo something and get it powdercoated. the Bondo would never survive the heat of powdercaoting and the powdercoat is baked onto the metal so all surface debris must be removed.

 

Powdercoat won't stick to Bondo anyway. Only metal.

The proper "show quality" way to do it is weld, grind the welds, then braze the joints with copper.

But even with raw welds, the pipes will look much better than crush bends.

Yes, mandrel bent will be much easier to make power and easier on your turbo.

 

Buy the bends...if you can weld you are home free! I welded mine, ground 'em down smooth, used metal glaze, concealing primer, ppg black and omni clear. They look like custom bent pipes.

 

IMO, a nice looking TIG welded joint on a mandrel bent pipe looks better than anything seamless.

Anthony...that's some nice looking IC pipe...must be a nice setup!!

 

Just get the JC Whitney piping.. I spent about $130 shipped for all the piping to do my setup.. And its easy to do yourself..
