Default questions about making fmic setup

those of you have run your own ic piping, where would you suggest ordering the piping from? also, how big of a pain is it to run a rotated intake manifold? i would assume that you don't have to run quite as much piping, therefore less lag

Either
www.mandrelbends.com
or I prefer
www.siliconeintakes.com

Their aluminum piping is beaded and also highly polished so looks great in the engine bay.

I have never ran the reverse intake manifold I know pluging something and drilling and tapping something else is involved but I don't think its that much work...
The gains of less lag are there, sure... But you have to realize the air moves sooo quickly in that piping that even if you shorten the route by 2 ft the gains won't be night and day...
Hope this helps a little.

lol well, i suppose the appeal of the reverse manifold is just being cool :P and how difficult is it piecing together different bends that actually fit properly? or would a better bet be to try and find someone who can bend the tubing?

The reverse manifold definitely has it's perks. It cleans up the engine bay by a lot and reduces fabrication by quite a bit. It also allows the piping to have far less bends and also prevents as much heat soak...

Siliconeintakes.com has more then enough pieces between aluminum pre-bent tubing and silicone couples to quite easily make your own fmic piping. But keep in mind the fewer silicone couplers you have the more reliable the charged air route is. This of course means more aluminum welding. If you are inclined to weld thin walled aluminum piping then this is something you can do too.

well, i checked out their large piping kit...luckily i have a friend that used to be my metal working teacher in high school who would likely help my mandrel bend things to fit just right...only issue would be finding somewhere to have the piping welded as i don't have the means myself

Order a universal kit from cxracing on ebay. Use the couplers for mockup, but buy nicer ones for your application. The tubing is pretty nice, I know a lot of local guys use it. I tacked mine together myself and had a friend weld it, but I know that you can tape it together and bring it to a welder and you'd be just fine. The key is to get nice, square cuts and no gaps, so that the welding is nice and clean.

I probably spent 4-6hrs mocking mine up, cutting the tubing, etc and I was in no hurry. If you go this route, have your welder weld a bead on the end of each assembled tube, to prevent couplers from blowing off.

^treadstone fmic? If so, how do you like it so far? Possibly more pics of your alternator mounting on that rotated manifold? Very clean looking setup!

Use a protractor, measure twice, ditto on the beads welded on the ends. To save time just have a 1" bead welded at four spots 90* from each other works great. Use 5 ply silicone couplers with reinforcement. Those rubber ones blow out at heavy abuse 0:-)
You can do it just take your time. Use a razor blade and a sharpie make line up marks for the welder. Then just number the joints 1-1
2-2
Etc etc
Good luck.

Yep. Don't have the car on the road yet, but I'm very impressed with the quality of the core, castings and assembly. It's a nice, complete package with mounting bar and everything. Definitely a recommended alternative to the APS cores that are getting harder to find. I'll do a full writeup/review after the car is on the road.
