Hello everyone! I have a new 2020 GT500 coming in September so its time to sell my 03 Cobra with 46,850 miles, I bought it with 28k miles Bone stock, ive had this car for a little more than 6.5 years and have about 3.5 years since the engine build with no real issues other than the alternator...

Does anyone know where the best place to get just the knuckle assembly is? Everything I find is the hub and knuckle, only the inner part of my left knuckle is damaged.

I have been data logging my TVS Cobra for a while and having it tuned, we got the pump 92 tune dialed in great and started the E85 tune, we have a problem with as soon as I go WOT or even rolling into higher rpms in any gear the wideband pegs at 10 afr and the car bogs down and acts like it is...

Does anyone know what caused this error and how to fix it? I can’t seem to find any info about it. It was working one day and then the next it did this.

I just noticed today that my TVS case is slightly lighter in some areas, the car was down for about 2 years and the shop cleaned it up before I picked it up back in November, they used a engine cleaner most likely from a parts store and ive used those before as well when the car had the stock...

Ive been trying to rule out everything I can before I try messing with the tune, the car has been face planting once in a while coming up to a stop in neutral, it doesnt always do it but ive just gotten used to downshifting to prevent it. The car sat for 2 years and had to have the Motorcraft...

Well we got my engine back apart after it blew the dipstick and pre filter off on the dyno, all 4 of the driver side pistons melted, everything else in the engine and heads look perfect with no damage to anything but the cylinder walls, pistons and rings. After talking to the shop and them...

I need some advice on fuel lines, I have a Lethal budget return system that reused the factory line, but I want to upgrade the feed line, I cant seem to find what fittings are needed to upgrade the budget system, What all is needed besides the line itself? Are rails needed or will stock rails...

My car was on the dyno last night getting tuned and on the 4th pull it blew the JLT pre filter off the passenger side cover and blew the dipstick up also, I also have a JLT oil separator on the driver side. It was making more boost than it should of with the cold weather, im running 92 oct with...

I had my cobra torn apart this winter due to low compression in #5 and #6, also found all the exhaust valves were toasted and had small damage to the seats, Its being put back together now and hopefully it will be done in the next week or so, in the process I wanted to upgrade things while I was...

Figured it out, this can be deleted

Im trying to buy SCT's pro racer package and the manual but the code says not valid, did the code change or does the it not work for these items?

Im rebuilding/upgrading my engine and am replacing as much as I can, what are the stock guides good too and what are some good aftermarket options? Ive already looked at MMR's race spec ones but they are a couple weeks out.

When my car is done being rebuilt/upgraded im going to be getting a e85 tune as well as a new 92 pump tune, what is there a good pulley combo that can be changed easily without having to change the belt everytime? I have a TVS with a 2.8 upper only right now.

A while ago I swapped a new TVS on my Cobra, I only got about 500 miles before doing a compression test to find I was low in two cylinders. Ford told me it was the rings... well turns out the rings are in great shape it was the Exhaust valves not quite closing all the way which is what caused...

Im in the process of rebuilding my engine and upgrading things while its all apart, ive already ordered better springs with more seat pressure, going to be using the stock cams. But what are the stock Roller Rockers good to? I havent found any good answer yet, I was thinking of getting the Ford...

I installed a new gen 2 TVS and didnt even get 500 miles before I found low compression on 2 cylinders and decided to go ahead and pull it apart and see how much damage there was and upgrade it while its apart. I dropped the car off this morning to get started on it, I figured I would replace...

I recently got a new Gen2 TVS installed and made 568whp and 535 wtq at 19.5psi and 15* timing but I felt that I was down on some power so I had our Ford dealership here do a compression check and found that cylinders 5 and 6 were down to 135 and 145, so this winter im going to tear it all apart...

My Cobra has been burning a little oil on first start up in mornings and at WOT, from the research I did and the techs I talked to it looked like it would be my Valve guide seals, so ordered those and dropped it off at my local Ford dealership to do them, they pulled it in to start them and did...

I just got my TVS and everything installed and got a start up tune from VMP to get it going before having them remote tune it, when I go to start up the car it revs up like a normal start but cant stay running and slowly dies off in about 5-10 seconds you can hear it trying to keep going but...

Getting closer to installing my new TVS, im pretty excited to make the jump from just a upper pulley Eaton, Ive been stockpiling parts for a while now to install everything all at once and get a remote tune from Justin at VMP. Ive seen numbers ranging from upper 580's to mid 600's, what do you...

Im about to install my new Tvs, Im just not sure what ill need in the way of new gaskets or seals to replace at the same time. Im pretty sure I have everything else that I need to get it going just curious about the small things.

I finally got my Cobra back to the track yesterday, Last time I went I ran a 12.4 @ 111 with a 1.9 60' when I went to get off the email tune and get a dyno tune a few weeks later I found out my Maf and plugs were shot so I got those replaced and put down 447whp and 466 wtq on a mustang dyno and...

So I ordered a BAP but after getting it and looking at the instructions I cant figure out what the plug on the side is for, I also didnt get a adjuster with the kit, this is the one I ordered http://www.latemodelrestoration.com/item/KB-89069/Kenne-Bell-Boost-A-Pump-Single-40amp Did I order...

Im going back and forth with just putting in a order for a TVS, on their website it says you can run a 3.3" pulley on stock fuel, has anyone actually tried this? and is it actually a stock fuel system or is anything required? Also how much power would you estimate at only 14 psi? My plan would...
