Cold air intakes Reply #120 – October 13, 2014, 02:44:53 PM Well I've started on a shield for the filter. I figure it's low cost so why not try it. So far this has cost me $5. I just got a office Rubbermade trash can from Home Depot and went to town with some tin snips. It needs a bit more work to sit better and some rubber weather stripping to seal to the hood bottom but it might end up working. Plus it will take in air from behind the headlamp area. The filter has a much larger area to draw air from vs the modified March Ram Air box. Quote Selected
Cold air intakes Reply #121 – October 16, 2014, 06:28:06 PM I sped the Rubbermaid trash can shield idea. I couldn't get it to look good. Went back to the March box. I figure if car have been into the high 11s with the entire March Ram Air kit that the box can't be that much of a restriction. Quote Selected
Cold air intakes Reply #122 – October 19, 2014, 06:52:52 PM Well I did a "scientific study" today between the stock air box with a K&N and the March box with conical K&N. I drove 80 miles to the track (about an hour and fifteen minutes). Air temp was 55* the whole day. I went through tech and just ran the car in street trim (32psi in the rear tires 16* initial timing March box and conical filter):60': 2.121E.T.: 14.229MPH: 97.09Bumped the timing to 18* initial and lowered the rear tires to 28psi:60': 2.101E.T.: 14.124MPH: 98.04That was the best it ran of three consecutive runs. All the runs were virtually identical. I then went back to the pits and disconnected the battery for 30 minutes. I fired it up and ran again:60': 2.144E.T.: 14.282MPH: 97.17So after that run I went back to the pits and disconnected the battery for 30 minutes. While the battery was disconnected I swapped the stock air box with K&N panel filter back on along with the correct sample tube for the MAF. I then ran the car again:60': 2.167E.T.: 14.296MPH: 96.96So what does this mean? In my case the stock air box and the conical filter both provide the same amount of power. The stock air box doesn't seem to be a restriction on my ~270rwhp car. The MPH change was well within a run to run variance. Quote Selected

In the spring an 8.8" rear with a 31 spline Traction-Lok, 31 spline axles, 3.73 gears, and CHE rear arms is going in. That along with a set of drag radials will get the car into the mid 13s as it sits cutting a 1.8-1.9 60'. After the rear upgrade then comes a custom cam and a Performer RPM II or Systemax intake. Gotta get the power I have down before adding 20-30 more horsepower. Quote Selected
Cold air intakes Reply #125 – March 18, 2015, 09:20:30 PM Dragging this one out of the dead..... I ordered a Mac CT9 sample tube (C&L equivalent - 099/Purple)..... Time for 30 pounders.I've been doing research as to just WHAT 30 pounders I want as the old school red top EV1's are unobtainium; even used. 30 pounders can mean many different things as well. Actual CC measurements from 300-330 can be listed as a 30 pound injector. Also high impedance can mean 12 ohm ... (factory for ours was around 14.5). It's turning into quite the ebay search because you CAN find a set of 8 injectors for $150 new; just gotta make sure they are correct.FYI -- the 2.0 in my 2012 Ford Focus apparently has 30 pound injectors (315 cc) with an EV6 body and a Jetronic/Minitimer connector, meaning they would work with a factory EEC-IV fuel injector harness......I'm looking for impedance data.

Also thanks to the accurate Autometer tachometer I installed I found out I've been short shifting the out of my car. Turns out when I thought I was up shifting (valvebody has the epoxy mod so I shift manually at the track) at 5500rpm I was actually up shifting at 4900rpm. I bet another 500 to 600 rpms would make a difference in trap speed.... Quote Selected

Red tops?I've been thinking about getting a set of 30lb injectors. With Edelbrock heads the car has to be approaching 90%+ duty cycle at WOT with 24lb injectors. I've got no lean codes though. I'm curious how your car responds to the calibrated C&L MAF with 30lb injectors. Most people seem to have no problem with C&L meters and 19lb or 24lb injectors. It's the 30lb and up that usually cause problems. Quote Selected
Cold air intakes Reply #129 – March 20, 2015, 11:06:10 AM Also as far as filter shields go this may be another option besides the March Ram Air box:It's a heat shield from JLT cold air for 99-04 Mustang GTs. It's only $39, which is cheaper than buying a new March Ram Air box: http://jlttruecoldair.com/ZenCart/index.php?main_page=product_info&cPath=132_137&products_id=383This is how it looks mounted in a 99-04 Mustang GT.It looks like it might be an option, depending on the angle of the piping used back to the throttle body.

Most people don't run a large enough filter or some other issue though. I think this will work nicely. Plus I can run it at stock pressure again. Less stressful on all the fuel system components.

Less stressful on all the fuel system components.I think a lot of the issues people run into with C&L MAFs and 30lb injectors is running them with the stock airbox. It states on C&L's site:19lb injector calibration: stock airbox24lb injector calibration: this tube for stock airbox, this tube for conical filter.30lb injector+ calibration: conical filterIn other words most people are doing it wrong.

Cold air intakes Reply #133 – September 09, 2015, 03:20:22 PM Well I changed some more stuff for fun. This is what happens when you sell some old parts and work some OT :hick:. I have been running a 76mm C&L MAF with their 76mm intake tube. The car ran great with no issues.Because hot rod I couldn't leave well enough alone. I have been interested in a slightly larger MAF that I could tune later one, i.e. one that had a better, actually usable transfer function unlike the C&L unit. So I purchased a 80mm PMAS slot MAF calibrated for 30lb injectors. It comes with a 30 point transfer function and has the benefit of being a new, 2005 and up, style slot MAF. I also replaced the piping between the back of the MAF and the throttle body with 3.5" diameter tubing because a bigger MAF means more airflow ;). I swapped this stuff on today. The car runs great without any issues. Upper RPM throttle response feels slightly better as well. Quote Selected
