Had new PS pump replaced. They also replaced the high pressure line from pump to hydroboost as the old one was leaking badly when they put it back on. It seems like it may still be leaking somewhat. To double check: Should the Teflon seal be visible like this? It's also whining at high RPMs...

Finally getting around to replacing the PS pump before my next track day. Should I also replace the lines (esp. high-pressure lines), or if they aren't leaking is it better to not mess with them?

Decided to do a compression test for a health check and pretty happy with the results. All were 150-152, with 4x 150, 1x151, 3x152. Doesn't seem too bad for a 22 year old car. Edit: the consistency (which I know is the main thing to look for) seems great, but are the results low overall? All...

Going to try Amsoil Severe Gear 75-110 instead of RP Max Gear 75-90*. I didn't put any friction mod in with the RP, do folks add any with the Severe Gear? I didn't think the amoils had any already in there, but their site does say "Contains friction modifiers for limited-slip applications" My...

Continuing my parade of "it's old enough to smoke and taking it on track broke it", I've found my piston dust boots are cracked on the front. Normally I'd just buy some reman Cardones, but I'd be sad (likely) losing the COBRA logo, already own sets of the seals/boots, and the job doesn't look...

doing my oil change for 20th time (or whatever) and it was unusually hard to get off. Not sure if it's because it really got stuck on there with the heat from track driving or because I did it with the car cold*. While initially getting it to move I noticed the entire "face" (in blue) was...

Is there any performance reason to pick a different plug than the TR55IX for an N/A car with just a JLT and catless exhaust? I know coppers like the regular TR55 and autolite 764 are cheaper, but the price difference isn't a concern for me, so just interested in performance differences.

Just got the car back from having a new clutch and flywheel installed* and unfortunately it seems my clutch cable is stretched to the point of needing to be replaced, as even with the firewall adjuster maxed it's loose. Is there any particular one that's better than the others? My memory from...

Is there any reason to go for LMR's new PS pump (or any other) over the Motorcraft reman sold on rockauto?

I'm considering replacing the finless power steering cooler on my '01 Cobra with the 03/04 Cobra unit, as I am boiling fluid when doing track days. In assessing this I'm trying to see where your cooler actually sits. Based on the shape it looks like it is positioned towards the bottom or at...

I've read the instructions but want to be sure: the evenflow/lethal performance head cooling mod involves tight quarters with getting to the freeze out plug but it's otherwise doable without having to remove anything major, correct? Also, I read somewhere that to remove the FOP one should tap...

I believe historically the Ford Performance ignition coil packs have been the preferred choice when buying replacements for our cars, but it's been years, production has moved to China, etc. Are they still the best choice? I haven't been noticing misfires or anything, but at 20+ years old and...

Sorry to resurrect, but about to put fresh fluid in the t56 I have from an '03 cobra. When people say RP synchromax, they mean this, yes? And are any friction modifiers required? https://www.svtperformance.com/threads/what-transmission-fluid.1003084/

Are (half-inch) intake plenum spacers worth it, and do they tend to help more low, mid, or high RPM? My memory is people were seeing small but real gains on them. Curious if opinions have changed over the years. $110 and I can do it in my garage doesn't seem too bad.

I'm looking to do what I can to reduce weight on my '01 Cobra for track driving (nothing competitive). Problem is most of the easy weight savings is over the rear wheels*, so trying to see where I have options to reduce weight on the front. The most obvious answer seems to be to pull the A/C...

I'm going to need to replace my leaking oil pan gasket in the spring. Given lowering the k-member appears necessary for that, should I also just replace the motor mounts? I'm assuming k-member needs to be lowered for that job, too. No particular reason to think they're ruined, but they are 20+...

As part of refreshing the rear end I need to replace the half shafts. All I can find at my normal online shops are the expensive upgraded ones for high $$s, which I don't need for a bolt-ons-only car. Has anyone used the ones off rock auto? They seem suspiciously cheap but I otherwise have no...

I have a set of '01 Cobra stock springs that have sat in a box since I bought the car from the original owner in '05. I believe the original owner swapped them out shortly after buying the car. Regardless, I got the car with 4600 miles on it so they are very lightly used. Free to anyone willing...

Trying to clean out my garage...before I hand 'em to a scrapper, is there any reason to keep (or try to sell) the stock springs and rear end gears? Springs are pretty close to brand new and the gears would have been taken out with <10k miles.

On track I am definitely cooking my power steering fluid. In order to prevent failure I'd like to DIY a cooler. Not sure how many other folks have done this, but I'm assuming I can just disconnect the 3/8 return-line hoses going to/from the stock "cooler" that goes in front of the radiator and...

I need to replace a leaking oil pan gasket on a stock pan. Can this be done without having to drop the k-member?

I've been having a blast with my '01 Cobra at the track but I am getting a little concerned about oil temps. First question is: should I be? Or is the stock setup ok for stock(ish) power? And then if I should be, what can I do about it? I thought dropping to a lower thermostat like the...

I'm trying to see how much material I've used up after 2 track days but am not sure on the thickness new. The one place I found something said 0.61in (15.5mm). Is that accurate and is that total thickness or just the pad material? I'm assuming that's total thickness, but assumptions can be...

About to do an oil change and as folks on here were so helpful with the alignment question I'm hoping to now get advice on oil choice. Traditionally I've put M1 5w30 in, but I'm thinking that's not the best choice for a car which sees the track. My M5 uses Edge 0w40, but I'm hesitant to put a...

Folks seemed to enjoy the last video so here's another from my 2nd trip a few days ago. This time I had new 275 width 200tw tires on 9.5" Apex EC-7s with camber of -2.4 front, -1.5 rear. Car did great! I managed 1:22 for my best lap and I think I could break into the 1:20s with better driving...
