I notice that Lethal Performance installed two of them, not just one. https://www.mustang7g.com/forums/threads/upr-s650-catch-can-development-lets-gooo.158383/

If it is beneficial for tracking then why do they not use two of them? Did you know that your engine has two places from which crankcase gases are recirculated, not just one? Why is everybody just installing one? We are "catching" the "gunk" from condensation in one, but not in the other...

As in, run two cars, one with a catch can and one without, and then do this? What is your hypothesis to be tested? What do you expect to find? Does whatever we are wiping end up as carbon deposits on the back of the intake valves? This is sort of asking me the same question I am asking. Is...

Everything I can find on the internet that even pretends to be looking empirically at the issue basically concludes, "Look! There is 'stuff' in the catch can!" That is not evidence that it is beneficial to the engine.

The intended benefit is to prevent carbon buildup on the back of the intake valves. Is this a problem on the S650 Mustang Coyote engine (this subforum) which still has port injection in addition to direct injection? If it is a problem, does installing an expensive, high quality catch can make...

Another vote for "nasty looking crud" or "gunk," but what is this, and is it harmful to be going into the engine? Posting that something is in the catch can does not mean that the catch can is doing something beneficial. Again, I am not arguing with you. I am not even disputing the point you...

114° - LOL. Wow. Not fit for human habitation. That air inlet temp on mine is on the next page, because I have another reading on that page that forces it down to the next page. My air inlet temperature is usually very close to whatever ambient temperature is on my dashboard for the...

Cool, another handling pack Dark Horse! I hope you are going to track it! :like:

You already know this, but maybe need to remember, the Dark Horse engine does not have the same rods and crankshaft as the regular GT.

Those two are different. I did not say never gets above 190° for either. All I wrote was that my oil temp "typically stays in the 190s." It has been over 200, but that is rare, not typical. Unfortunately, I did not pay attention to it on my track day (I was paying attention to not leaving...

#1 - I am not obsessing with anything about oil temps. I simply made an observation. #2 - I never see 230° driving around in any weather. Mine typically stays in the 190s. #3 - Right, it does have nothing to do with the grill hole mod. I just noticed this on the video. If this is normal...

I set them on the console around the shifter, and I have this frequent problem of the sunglasses flying into the back seat . . .

Are the catalytic converters still there or gone?

All stock engine internals . . . cool! :sunglasses: Ok, the video starts with filling up at the pump. Was the dyno run on E85 from the pump at a local filling station or specially purchased VMP or other provider? EDIT: Further into the video the question is answered, "straight from the...

If my oil temp hit 228 on a cold day when I am wearing a coat, I would be very concerned for what would happen in July on the race track.

Before anybody responds to this post . . . it's a joke

If it 47 degrees outside, and his oil temp is at 228???? It is August in Georgia, and mine typically sits around 190.

It increases horsepower by 14 from 486 to 500 Matches the Dark Horse

Most of us are thinking, "Cool. It's great that they can tune these cars now."

I do not know if you have a reading comprehension problem or you are so motivated to dispute whatever is posted that you are not slowing down actually to read it so that you can comprehend it. Read the post you quoted again, slowly, and then figure out why your question, "This car has custom...
