How much gain over twin IC w/ FMIC?
Who's switched from twin's to a FMIC setup? Are the gains worth it? Seriously considering it since my project is taking a little longer. Not fond of cutting the front clip but I'll will if it's worth it.
Any problems w/ the front clip sagging after removing the bumper supports? Any way to keep it from saggin if this does occur from removing the bumper supports?
TIA!

From everything that i have read the single front mount is much better than the twins. There is a lot of discussion over at the ls1tech.com boards.
When doing this mod you have to ditch the middle honey comb section on the bumper support. I wanted to retain some of the honey comb and fog lights, however the way the intercooler is set up you have to ditch the center section and alter the brackets for the fog lights.
The fog lights don't interfere with the FMIC too much... maybe 6 square inches at the most.
Here are some pictures of the work in progress.






I realize that the intercooler was hanging too low in this picture so I had to cut more metal off of the main bumper support so now its even with the air dam bracket. I'm also thinking about cutting off the bumper cover flap on the bottom to increase airflow.

As for the bumper supports to keep the shape of the front bumper... you're probably going to have to custom fabricated like the LJ's

BMR had one that incorporated bumper support tabs but they don't make them... I believe it was a one off deal for their project car and there are some liability issues with it too.

That's exactly the way I want to do mine! I was going to run the intake tube on the other side. Then I was going to relo the battery. What size intercooler, piping, and bends did you use? What kind of supercharger?

When the motor comes back I can finish mocking up the piping and either have all of the pieces welded together or just have a bead welded around each of the pipes.
I bought all of my parts from a vendor on ebay... turns out they're in Ontario so I took the 30 minute drive out there for a killer deal!
I bought the 31x12x4 OBX intercooler, 6 pieces of 3 inch aluminum piping, 6 silicone couplers, and 12 T-bolt clamps for well under $800-1000 that some companies are charging for a PNP FMIC kit. Its not rocket science.
As for the bends I have about half of it done... can't finish the other half till I get my motor back from the engine builder. There will be some additional silicone reducers and clamps to get the the MAF on but I don't see it costing more than another $100.00. Hope that helps!

P.S. I just realized that I bought some fuel lines from you! LOL!

looking good. wow thats a good deal for the intercooler setup. running mine almost exactly like yours. havent removed the bumper yet but does the honeycomb material give any support to the nose? i see you were able to leave some on the sides.
Re: How much gain over twin IC w/ FMIC?
I put my little intercooler from ATI up front for now and noticed little affect on the bumper with the center cutout and the bumper supports gone.
The intake temps seem to be lower too instead of when it was under the car as the air is directly hitting it instead of having to get feed in thru a scoop- not to mention I think it looks pretty bad-***...
If you aren't runnin a D1, the 2-core should be fine with a lot of smaller applications. The benefits are that you can fit it in there, keep the factory crash bumper and keep the factory fog lights in their respective place.
Here are a couple pics- its was right when I got the car done and hadn't totally finished the install, bumper still needed finished but wanted to drive it!!

blown383 and Procharged thanks for the pics! Looks great! Who is LJ and do they have a website? I remember BMR building that bar and not selling it to the public. Maybe there is some hope after all in terms of putting the FMIC and not having the car look totally cut up.
Re: How much gain over twin IC w/ FMIC?
Thanks Blown. Looks like I'll be surfing ebay because if I wait for someone to build a kit it'll be 800-1100 bucks! Why doesn't ATI make a FMIC for D1 F1 applications? I already called.
