  1. I hope you have time to sit down and pat yourself on the back for this, its F'ing awesome!!! looks like Kenne bell made it.
  2. :stupid:
  3. looks awesome!
  4. Hey thanks again for the props again. My SCT chip is going back for a reburn by Don Lasota at Lasota Racing, great guy and one of the best tuners with experience with KB's.

    Update on the dual meth nozzle setup. 6 gph nozzle before the scews pre compressor and intercooler. and 9 gph at the 3" discharge pipe. I was suprised to find that the meth lowerd my A/F by 1.5 points know seeing 12.3 A/F at WOT, BUT No reduction in ACT temps at all. In fact as the temp out side have warmed since first trying the intercooler, now with Intercooler and meth I'm seeing about 15 to 20 degees above ambient. Still really good, but thought the meth would have done something to lower ACT temps. My A/F is still kinda high 12.3, so I havn't tried my switch position with 23* timing. The car runs so good now I can't imagine wanting more. LOL
  5. damn if you could make another i would be VERY interested, i plan on doing a KB for my dart 347 and want to push some major ponies, havnt decided what KB im gonna go with but im shooting for around 800hp, let me know if you'd be able to do another, maybe in black :)
  6. I'm not sure what you mean by do another. The fitment of the intercooling pipe to the KB manifold has to be done by hand on the car, it can't really be precut by me for your engine bay. I just went slow used clay and cut and shapped the pipe tp fit under the hood. I can give you a parts list and guidance.
  7. then lets do that, only thing i ment by doing another is i dont have a welder thats gonna weld aluminum like that
  8. Ok guys, I said I would do a DIY and build list thread for my Fox body KB A2A project. I had most of this on another thread but this is step by step. I hope this thread helps other fox owners to find and search for this idea.

    ]Parts list
    3" intercooler pipe all 18" length

    2 U bend
    1 S bend
    4 90 deg L bend
    1 staight pipe

    6 striaght silicone 3 ply couplers
    2 45 deg elbows
    16 stainless steel T bolt clamps

    I baught this from from CX racing and I called them and had them sub i straight pipe for S bend pipe and 2 silicone couplers for 45 Deg elbows. They were very nice and didn't charge extra.

    Intercooler also from CX racing 31x12x3" with 3" inlet outlet

    For bypass relocation

    I used a piece of 1.5" pluming pipe from harware store 16" long with a 90* bend at the end. cut the end to make it fit.

    1.5" 45 deg silicone elbow

    1.5" ID greddy flange that was welded to 3" pipe

    1.5" 45 deg bend heater hose

    COST $$$$$ with shipping

    Intercooler $100 Ebay cxracing( 5098)
    pipe Kit $100 Ebay cxracing( 5098)
    1.5" 45 elbow $17 Ebay siliconepros( 339)
    1.5 plumbing pipe $15 hareware store
    Greddy flange $12 Ebay wyntonm( 12149)
    Welding $88 Look around there are many that can TIG weld.
  9. With manifolds removed from compressor start openning up the 2 areas that the 3" pipe will be welded to. On the discharge side you must first take measurements and mock up a piece and use clay to assure it will fit under hood and around the fuel rails and sensors. Just use a 3" pipe like I did and clay to check fitment.
  10. Here is how I went about cutting into the manifold. Don't be shy here just dive in, its not that hard. The first cut was with a drill so I could get my little jig saw in. I also used a carbide bur for aluminum alot of the medai removal and final shapping.

    Here you need to remove and cut into the bolt hole boss to take advantage of the 3" pipe diameter. Also I don't have pics but the roof area where it say Kenne Bell on top was partly cut out and removed later for more flow.

    Here on this end like I said you have mock up your 3" pipe cut it at an angle that will fit then scribe or mark with perm marker the area to be cut out. Then just cut man.

    Here is the area of the roof that needs to be cut out between the bolt holes for more flow. As you can see the shaped 3" pipe is raised 3/8" above the manifold to take adavantage of the full 3" pipe area . Make sure you measure and use clay though it fit with my car.
  11. Pipe fitment and shaping takes some time but its not that bad. I cut all my pipe with a radial arm saw with a regular 10" carbide blade, it works but be carful and go slow as it can grab the aluminum and throw it too. I also used another mider saw with a cutting wheel for some shaping and cutting smaller pieces. You can cut all the angles as well just go slow.

    This pipe fabrication and fitment took the longest. The hard part was making sure the bend would clear the brake fluid cap area and of course it had to be angled down and also flatened and somewhat squared to fit the end of the KB discharge open area. I went slow and it took me about 3 hours to get it right. I can't remember the angles I cut but it wouldn't matter anyway as I'm sure there are slight differences from each vehicle and engine.

    The next pipe inline is the S bend with the white rap that goes into the hole which is used for the windshield washer tank. Yes that means tank no more.

    This is a pic of the inside of the drivers fender well. Take out the liner and its all exposed, tank and horn removed for installation of the next pipe that joins the S bend. Here you need a 45 degree silicone elbow and then a 90 deg L pipe. And below that one is another 90 deg L pipe that joins to the intercooler. Yes one side done.

    Here is the front where it joins up to the intercooler right side of the pic.
  12. Now for the other side intercooler (cold side) leading back up to the KB discharge start out from the intercooler with a U bend pipe.

    Here in this pic from the top of the engine area you can see how the U pipe joins nicely with the intercooler and then ends up in position to lead up between engine and frame rail. I also had to trim the plastic shirt for the pipe in the end, its pulled out of the way now. Oh yeah the black box which is the charcoal canister has to be removed along with the metal bracket. Just unbolt it.

    The next pipe here that connects to the U pipe is a 90 deg L that had about 3 inches cut off the short end. I would advise checking your own fitment here before cutting.

    OK from this pic you can see the next pipe is the one next to the alternater and it is joined to the lower pipe with a 45 deg silicone elbow. This pipe is one half of a U pipe I cut in half. The other half was used at the beginning, driver side pipe to KB manifold. The one I spent 3 hours shaping.

    The next pipe here has to be cut and you will have to make your own measurements to make it work and fit for your car. I cut it from a 90 degree L and both ends were cut. I shortend the straight end to leave me with enough room for the pipe that is welded to the KB discharge manifold. And the other end with the curve had to be cut to join to the pipe at its curve the one next to the alternater.

    Here is how it should look from other angles

    You can see her is used clay points on the pipe area to make sure I had hood clearance.
  13. I gues I could cover mounting the intercooler too. My obseravtions are if you use a 31x12x3 intercooler the A/C heat exchanger could be retained, however I tossed mine anyway. I would have preferred the 31x12x4 intercooler for its better cooling and flow. That one I'm sure it would be very difficult to retain the A/C heat exchanger. I didn't remove the front bumper or cover I did all my mounting from inside the engine bay as I removed the radiator which gave me plenty of room to work. The only trim work I had to do was on the sides of the bumper cover where it looks like a mouth opening. And that was for the ends of the intercooler the inlet outlet area where the pipe connects. I used a stiff type razor blade or carpet knife for most. I just kept shaving slices out until It all fit. Check out the pics. I also did some work openning up the mouth area of the cover to get better air flow on the intercooler. It does change the look, but I'm going for maximum effect here.

    I used screws to pin the mouth up to the bumper support and drilled holes in the bottom and used zip ties to make the lower lip thinner.

    Here is where I clearanced the inside of the front bumper cover to clear the 3" pipe.

    Here the intercooler is bolted with the supplied brackets to the black plastic bumper support on top and below I bolted it the bottom of the radaitor support frame.

    Here you can just barley see one of the bracket bolted on to the bottom of the intercooler and radaitor support.
  14. This is what it should look like in the end. If it doesn't do some more polishing :) LOL.

    Frankenstien Kenne Bell. Check it out.
  15. *Cartman*
  16. So how long till its in a mag? I hope you have submited it because that is killer! I dont think I have ever even heard of an air-to-air intercooler on a positive displacment supercharger before :shrug:
    I could see that car on a cover :nice:
  17. Im not a fan of kenne belle's on winsor motors, but that is pretty cool, im curious to see what kind of power it makes...
  18. :hail2: :hail2: :hail2: :hail2: :hail2: :hail2:
    you are the man I would buy you a beer if i drank, so im just gonna settle with a A&W and more of these

  19. Thanks guys. I have tried submittiing my car via email with pics to 5.0 Mustangs and Super Fords magazine and have not yet recieved a reply. maybe I need to call. Ohh yah by the way I found a Mustang Dyno shop 3 hours from here and will be setting up and appointment in 2 weeks. Can't wait to see the drums on fire.
  20. I would email pix to keene bell maybe you can find away to help them sell more blowers
