So today my buddy came up and wanted to help address my it issues and reload my tune.
Some mod info:
2015 gt w/pp manual
Jlt intake
91 bama tune
Mrt h pipe
Roush ab
Mak cat delete (next week)
So since all mods and tune have been installed, I feel like the car had lost some power after loading the bama tune. I took the car down to the drags and made several passes. Sea level, 75*, street tires.
First pass ran a 2.2 60' & a 8.8 8th. Booo.
The next 5 or 6 passes were pretty consistent with the first. Rolling the clutch out and not trying to launch at anything above idle. I'd make 3 passes back to back and then let cool for 30mins or so in between passes. By the end of the night I was able to see an 8.2 8th and 8.6 with a 1.9 and 2.0 60'. So my buddy said it was driver mod and I needed to work on my launch and try and get my 60' down and I should improve my time.
Blah blah blah, what does this have to do with diy.
Well my iat Temps have been pretty high imo above ambient. For example today it was 85*f out at 10am and my iat"s when stopped at a light rose as high as 177*f, when driving they would drop down quickly to about 151*f but go no lower still felt like this was pretty high and way above ambient.
So we popped the hood and god damn, you could feel the heat just rolling out. We left the hood open and bs'd for about 20 min. During this time I reflash ed the stock tune back on and then reloaded the bama tune. Some other mustang owners said that my power loss could be from the bama tune resetting and I would have to reload it/happens all the time. So that is what we did, couldn't hurt.
After that was done we started looking in the engine bay, it was still pretty warm to the touch. Hot in fact but not as hot as it was 20 mins earlier. So we took off the engine shroud, yeah that thing was storing a bunch of heat, took off the valve shrouds and then decided to address the jlt heat box. Where the intake sits on the box, there is an area that is open and allows the engine temps to creep into the intake. Not good, basically turning my cai into a hai.
Now the diy, quick drive to the hardware store to test the tune upload and a 5$ piece of plexiglass and a roll of weatherstripping, we are in buissness. Time to make a jlt cai cover and weather strip the gaps. After an hour of bsing and crappy razor cuts we had a prototype. Lol, we put it on and went for a test drive.
Earlier when we went to test the tune reload and visit the hardware store, we got some base numbers with out the jlt cover under normal driving, stop light to stop light and wot pulls. Before the cover was on at 1800' 85*f, my iat were 175*f at stop light to stop light and dove down as far as 150*f under acell and wot.
After the cover was placed over the jlt cai and all gaps sealed, dust shroud removed as well as valve covers, we headed out on the same route we took for our base numbers. The outside temp has risen to 96* as it was almost 1pm. While driving normal, my iat's were between 103 and 113*f and at a stop to stop traffic rose only to 117-120*f. We thought, no way, so we drove around for another 20 mins switching between normal, wot and stop and go. Temps never rose above 120*f and that was sitting at a long light. I returned home and decided to let the car idle I. The drive way for an additional 10-15min. The highest temps rose to was 147*f.
Heat issues solved for the moment with a simple jlt cover and gap fill.
Couple pics to end this long ars post! Open to comments and criticism.
Also this is just a prototype, my buddy plans.to help me make a cleaner version of this out of lexan and a vacuum form so that it can easily just slide right over the jlt box. Patient pending, Testing will commenced over the next month or so
