propeine Posted March 30, 2003 Report Share Posted March 30, 2003 I'm anxious to see numbers from all of this. 3 designs, one I have no clue how it works, 1 I've helped with, 1 I made. We're gonna need to have an intake shootout. All on the same car though. Do I hear a meet somewhere? Tom Link to comment Share on other sites More sharing options...
shift1313 Posted March 30, 2003 Report Share Posted March 30, 2003 im gonna try to get a hold of a gtech and do a before and after with my car. since the intake isnt the only thing that changes its kinda tough. great idea though. Link to comment Share on other sites More sharing options...
Funky Phil Posted March 31, 2003 Report Share Posted March 31, 2003 http://www.me.psu.edu/me415/SPRING02/intake/2001plenumlong.jpg yeah if any of you remember them the old escort EXP had an intake just like that with the curled runners and they seperated in the middle for ease. So you could bolt on the bottom half of the runners and then the top half with the plenum on it. Link to comment Share on other sites More sharing options...

CHC Posted April 1, 2003 Author Report Share Posted April 1, 2003 well, I got my first aluminum plate today. I already have the design layout scribed on it waiting for cutout. I just need my other 2 or 3 plates and tubes to come in to get it rolling. Will post pics when it is under construction. Hopefully by this weekend.

propeine Posted April 1, 2003 Report Share Posted April 1, 2003 congrats, im anxious to see some photos. Its probably going to be until mid may before I can actually get somethin produced. College = no money. Tom Link to comment Share on other sites More sharing options...

They are 1 1/2 ID by 15+".... Link to comment Share on other sites More sharing options...
propeine Posted April 1, 2003 Report Share Posted April 1, 2003 I will definitely let you know after this weekend. I'm gonna grab my head, my TBI unit etc and do some measuring but that could work out well. Are you doing the whole intake out of tubing or are you using sheet as well? Where did you get your aluminum from? All of it off of ebay or from some supplier as well? Link to comment Share on other sites More sharing options...

But yes, all off ebay. It also looks like I may have some extra planks left. The plenium will be of the 1/4" plating, and have 4 runners come off that to the intake/head flange of 1/2" But yes, I did get all my stuff off ebay. Just had to take time and get what I wanted.

propeine Posted April 1, 2003 Report Share Posted April 1, 2003 sweet. I did some looking today and one of the primary companies that sells alum on ebay is right here in rochester. Keep me posted on what you got left though, that 1/4 in might be useful. Link to comment Share on other sites More sharing options...
CHC Posted April 1, 2003 Author Report Share Posted April 1, 2003 sweet. Â I did some looking today and one of the primary companies that sells alum on ebay is right here in rochester. Â Keep me posted on what you got left though, that 1/4 in might be useful. Right now off hand I will say I will have 2 8.25X10.25 plates left. I am debating on how many 1/2 pieces to weld togeather to get a good bolt run-through anchor. I will probly just go the reg 1/4 cap, and 2 1/2 plates and have 4 threaded anchor sets welded to the 1/4 facing outward. Think of this way. the 1/4" plate. 4 threaded anchor caps, then basically 1" of aluminum over that. Not sure on the bolt length though, I think the T/B is 3-3.5" thick, so add 1-1.25" on top of that. But that way I know the intake will not be susceptible to blow out while under high boost conditions. I think the caps are 3/8" by 1" and have a 1.25 round mounting plate on the bottom. So that mounting plate would be behind 2 1/2" thick plates that are welded togeather, then they are welded to that 1/4" piece. I would like to mount that plate behind the 1/4" piece, but I do not want to run even the slightest chance of leaking around that mounting plate. as that would be all there stood between pressurized air and the open atmosphere. At least the way I am planning on, it would have to go through some very heavy welds to reach daylight. ;D Link to comment Share on other sites More sharing options...
shift1313 Posted April 1, 2003 Report Share Posted April 1, 2003 1/4" thick aluminum will hold a lot of heat wont it? Link to comment Share on other sites More sharing options...
CHC Posted April 2, 2003 Author Report Share Posted April 2, 2003 1/4" thick aluminum will hold a lot of heat wont it? well, thats the thickness that the majority of intakes are made of. And remembering, that the intake is on the opisite side of the turbo, and Aluminum sheds heat alot faster then other metals. Link to comment Share on other sites More sharing options...
propeine Posted April 2, 2003 Report Share Posted April 2, 2003 thats a good point about the heat. I agree that many intakes are 1/4 or more but if you look on any of the aftermarket ones most are much thinner. How much boost are you planning on running? I think I've finally got all the numbers worked out for matt and I's intake design so now its just a matter of making sure everything will fit properly. Cad is so lovely for such things. Shouldnt be too long before we can have a shootout though. Keep me posted. If you ever wanna shoot the crap on IM hit me up. My name is the same as it is on here.

CHC Posted April 2, 2003 Author Report Share Posted April 2, 2003 well the vast majority of intakes I have seen, range from 3/16-3/8 in thickness. factory ones tend to be a little thicker, but most aftermarket do no go thinner then 3/16. I "could" have dones in 1/8", but for the future plans o running high boost, I just did not want to take any chances. I am just more comfurtable welding thicker aluminum then thinner, since I do not have a TIG welder. But the one I have can easily do 1/4" aluminum.

CHC Posted April 3, 2003 Author Report Share Posted April 3, 2003 Well, I got all the aluminum, and I am having it machined as we speak. Hopefully, it will be ready by this weekend. Link to comment Share on other sites More sharing options...

CHC Posted April 4, 2003 Author Report Share Posted April 4, 2003 well, I am takin my time on the intake. Afterall, I am having to ... 1. replace timng chain. 2. build Mega comp. 3.build intake. 4. save & buy 4 injectors. 5. currently rebuilding the T.B.I unit(looks 1000% better!), and sending injectors to cruzinperformance for a good cleaning. 6.Insatll new timer unit. 7. Install new BOV unit. EDIT: forgot to mention the head rebuild, and stock exhaust manifold modifacation. Link to comment Share on other sites More sharing options...
shift1313 Posted April 5, 2003 Report Share Posted April 5, 2003 you cant use a BOV until you get your megasquirt going. the stock computer will only accurately give fuel if you use a bypass valve. otherwise it will be rich. Link to comment Share on other sites More sharing options...

Â the stock computer will only accurately give fuel if you use a bypass valve. otherwise it will be rich. bypass valve? but even if it did run rich? that would not inhearantly be a bad thing. But also would that only happen when I shifted? as that would be the "spike" that the ECM/O2 would see? Link to comment Share on other sites More sharing options...
shift1313 Posted April 5, 2003 Report Share Posted April 5, 2003 running rich is almost as bad as running lean. you would have unburned fuel left in your combustion chamber possibly and that could lead to preignition, in that case i sure hope you dont have hyper u pistons. Not just when you shifted but whenever there was a change (drop) in boost or whatever its set at. The mas reads a certain amount of air and the ECU takes that as the know all end all and supplies an appropriate amount of fuel based on a few other things. if you use a bypass valve it will not just vent to atmosphere. it would route back before the turbo but after the mas so you dont 'loose' any of your air. running rich as stated above has potential to be bad depending on how rich. id also imagine it would slow down your throttle response. Once you run your stand alone you will be fine with a blow off valve, unless you decided to put a maf in like you said on the megasquirt post then your back to square one.

CHC Posted April 6, 2003 Author Report Share Posted April 6, 2003 http://www.geocities.com/my86tsi/intakeprojects.html was waiting for that to show up. Main reason NOT getting that... too short of runners. Oh, yeah and the $700 PRICE TAG. Mine is costing me under $100 for time and materials. And it has as stated earlier, 12" tuned runners. By tuned, each runner holds 1 intake charge, so flow and velocity are maximized. and it does not have the "dead" zones in flow that are inhearant in the "LOG" intake's design.
