Finally got my car back to the track. My old setup was a Paxton, E85, 3.33 pulley waste gated to 11psi (yellow slip). Last week, now with a built motor, 3.33 pulley and no waste gate (white slip). I gained just shy of 3/10ths but MPH was nearly identical, which I find weird. Also, I asked my...

How do you know when the head units need a rebuild? Mine runs, isn’t terribly noisy, but when datalogging, my load and Maf lbs keep decreasing over time. I have a 3.48 pulley on it currently and load peaks around 1.55. It used to peak around 2.10. I also used to peg the Maf sensor, and now I do...

How many pounds of boost do you see with the stock air intake? I thought I had belt slip so I changed from a 3.33 to a 3.48 pulley. The tensioner is pretty much topped out now with the 3.48 and the idler in the second from the left hole. I made a homemade boost leak tester and found that two of...

14 GT with a Paxton. Trying to figure out the cause of this but can’t think of where to start, honestly. The problem I have is that when the weather is warm and/or humid, under part throttle the car feels like it’s hesitating or maybe misfiring. It’s subtle but you can definitely feel it. While...

In May 2018, I went to the track and ran a 10.5@137 but then broke my OPGs. I rebuilt the motor with forged internals, put in a Mantic clutch, and an Eaton Truetrac. I also changed slicks to a stiffer tire. Last night I finally made it back to the track. I started with higher tire pressure and...

I just wanted to share my experience, in the off chance it helps someone else out. I’ve been driving my 14 Mustang GT off and on this winter and after 15 minutes or so of driving, the wrench light would come on and the car goes into limp mode. It throws no codes and if you turn the car off and...

My right turn signal on my dash was blinking really fast so I checked my turn signals and found the rear right signal is not coming on. When the brakes are applied, all the lights are on. The front blinkers are fine and the rear left signal works fine. It’s just the rear right signal. I cannot...

Here is my setup: 2014 Mustang GT Paxton 3.33 pulley Exhaust: Kookers Super Street Shorties Lethal offroad X Lethal OTAs GT500 axle back It sounds fine, it's just not loud enough for my taste. On my 13 GT I had the Roush AB and loved the way it sounded. Still had cats though. So just looking...

Which two wires are the ones to check for voltage with at the fuel pump control module? I’m trying to narrow down a fueling issue during WOT.

So my machine shop ordered my rotating assembly and bought my Manley rods but didn’t get the ARP 2000 bolts (because I forgot to tell him to). He balances my rods/pistons/crank, and I got it all back yesterday. So I decided I wanted ARP 2000 rod bolts and went ahead and ordered them. My...

Finally got some nice weather and was able to get to the track. Ran a PB of [email protected]. Third run out, oil pressure light came on, car won’t start. Waiting on my tow home. That’s the way it goes when you gamble I guess. FML.

Pre-E85 I was running 10.8@128 with 1.5 60s. Post E-85:

How long does it take for your fuel pressure to return to 0 after you turn off the car? Mine goes to 0 almost immediately and when I start the car, it takes a little effort for it to turn over. I’m tuned for E85 and have VMP fuel rails. I’ve checked the connections to make sure they’re tight...

Vortech Maxflo Boost a pump. Works great. I removed because I installed a return style fuel system and no longer need it. $100 shipped.

I have two working fuel pumps out of a 2014 GT. One comes with the floater and the other does not (you can transfer yours over easily). The one WITH the floater was on the car from the factory until roughly 6,000 milers were put on the car. The one WITHOUT the floater was on the car for about...

I have two Bob’s Oil Separators for sale. The Ultimate Firewall version for the passenger side and the regular version for the drivers side. Includes hardware and hoses. These are both matte black. They were on the car for roughly 2,000 miles. $250 shipped for both. (They were $400 new).

I purchased a new ABS Control Module from Ford Parts. Have any of you ever done this and then had the dealership flash it to your car? I didn’t realize it wasn’t plug and play until after I installed it and my ABS and Traction light were blinking constantly. I was curious what the dealer charged...

I installed my fuel system from Rodeheaver’s and got all the lines tightened up. I had some issues with the pressure slowly going down, but I think I’ve corrected that. I have the pressure set to 60psi. When I try to crank the crank car over I can hear the starter trying but nothing happens. It...

I’m installing my fuel system and I’m trying to figure out the boost reference for the fuel pressure regulator. The instructions with the system says it should be boost only and on a Paxton car to use the line by the throttle body. This happens to be the same line going to my blow off valve. I...

While on SVTP, this ****ing Amazon phishing bullshit pops up every 10 seconds. I’ve read it’s an issue with the website. Anyone else get it on here?

I just picked up a return fuel system yesterday and once it gets here I’m switching to E85 with a flex fuel tune from AED. I wanted to see what kinda of ET and MPH gains you guys got after going E85 while having a power adder.

A while back I had a 2013 Mustang GT base model that had three lights in the overhead console. The middle light was on at night and would shine down on the shifter and radio area. My 2014 GT premium doesn’t have that and I can’t find any example of my 2013 anywhere... Does anyone have that...

I put in a Mcleod Extreme Street clutch and PP with a Mcleod lightened steel flywheel. I’m 100 miles into the break in process. When using reverse, stopping, then trying to go into 1st (or 2nd), I cannot. It won’t go in at all. I can use 3rd and start going, then 1st and 2nd work just fine...

Whenever I turn off the Advanced Trac (hold button for 5 seconds) the brakes start to act funny. If I slide the rear end at all, the brakes come on and sound like they are grinding. If I merely take an on-ramp at a speed above 25mph, the brakes apply by themselves and I feel like I’m about to...

I’ve been having issues with my coolant being low lately and I cannot find a leak anywhere. I just emptied my Bobs oil separator and the oil has swirls of milky stuff in it. So I’m curious if the oil separators could cause the pressure and blow a head gasket or if it could be internal engine...
