i just went to autozone and picked up some liquid steel. its a 2 part epoxy putty. i shaped the air foil by hand and then used my dremel to smooth it out. then just drill a hole for the IAC and your done.

total investment was $5 or less for 2 tubes of epoxy

Not bad, it be better if it actually did something.

 

its gota be doing something because i did that and an electric wp and from 80 degree weather to 95 degree weather i picked up a solid 1.2 mph in the 1/4 i went from high 107 and low 108 to high 109s

 

Looks nice, but I'd be worried that a little piece could get sucked into the intake. :O

and for some reason I was thinking I'd see an air foil by reynold's. hehe, anyways, looks like a pretty good job, just make sure it stays put like they said.

 

Ditto, Liquid Steel does break off sometimes....You should coat it with some type of paint or Glue that you could brush on just to be double safe.

 

Brave soul indeed. Your work looks fine, but I too would have some reservations. Most of those cold weld expoxies (I think) are for gluing, not fabrication.

I wouldn't put anything that might wind up on top of my pistons in the intake just to save a few bucks.

Good Luck.

 

Your old air foil works well on my car.

 

I wouldn't trust that in my intake, all it would take is a tiny piece to come off and the 20 bucks you saved gets multiplied by 100 or more once that particle gets in there.

 

Yeah, I don't know if I would totally agree with the process. As stated, liquid steel really isn't for molding things. I tried it in one of our kart engines to smooth out a port job that a guy did on it (crappy), after a few races, alot of vibration and heat, it started to peel and ended up in between the valve and seat. Not good.

If I was gonna make my own, I'd fab it out of an old piece of wood, that way you can bolt it in

When my lil girl turns 18 and I can afford to get my CNC, i'll start cutting them up

where did you get that idea from? has your source found it to be reliable? ....personally id be too afraid to try it.....but your work looks good - i wonder how well it will seal over time...

 

yeah...you know those Liguid still things are pretty easy to knock out of place right. One good thud and it will fall right out of place. They don't hold very well at all. If you really want to make it fail proof. Tap the TB a couple of times till it falls out (it will). Then Coat it with an expoxy glue, then spray it over in some Hi temp Paint...Just drill some holes in it so it aligns up to the Factory foil screws...(Mine has some type of screws in it for some reason) then secure it in place. But with engine heat and Vibration it will probably come loose.

 

its been in there for about a year with no problems. i took the drill and scared the surface really well for it to hold too. there is still no cracks or anything in it, looks just like when i first put it in.
