Can't help myself Recursion: Definition- see "Recursion"

Yes, capping it off would be bad. Another reason to be very careful about shade-tree mechanics posting info online! I mean it's not like Ford has actual engineers doing this kind of stuff- you should immediately jump to the conclusion that they purposely built in a boost-leak! I guess because...

Don't get me wrong, I'm not saying you shouldn't buy one, that's your choice. It's just my opinion that it's just not a practical device in that it doesn't demonstrate value for the money. From my point of view, if it goes off and you slow down, that justifies that it saved you a ticket...but...

Think of the money you'd save by not speeding, blowing through school zones, or running stoplights! I'm all about personal freedoms, but with that comes personal responsibility. I regularly run 9 mph over on the highway and haven't had a ticket in 20 years. When I used to live in Tucson I...

You're right, physics hasn't changed- but you're missing the point. The 9HP calculated in that article is simply an approximation of overcoming wind-resistance...period. It does not take into account the HP to overcome other parasitic elements in the drivetrain: run the oil pump, water pump...

Really? I'd truly like to see some documented evidence of 9HP at 60 mph! As far as "it stands to reason if the engine can produce enough horsepower at 10% vs. 13% it'll use less gas". Not necessarily true. Do a google of BSFC maps and look at one. BSFC numbers when mapped against RPM and...

Is it judged "by ear" or by instrumentation? I assume there are also points for craftmanship and aesthetics?

Shout out to @AtlasBlue2022 for going above and beyond in trying to help. I concur- recheck everything.

If I could add a bit to my last post in this thread. Consider the engine as a "system". If you're running high ethanol blends, I would not be running colder plugs. The latent heat transfer of ethanol is higher than that of gasoline which lowers the heat range of the plug, altering it's ability...

It's likely at those HP levels there isn't enough injector or pump to support higher levels of ethanol.

I'm a big fan of this exhaust as anyone who has read my thread: https://www.explorerst.org/threads/for-those-thinking-about-a-performance-exhaust-system.2775/post-33847 might imagine. I have no idea what it sounds like; that's not my area of expertise, but I like a well engineered solution.

Cuz he's doing it right from a performance perspective. Share some sound clips please!

Are they doing this all at the same time, or did you have the mods you listed when the engine blew?

What are your "custom" turbos? Has Livernois given you an estimate of max RPM with stock internals- are they upping the rev limit? What fueling are you planning for 700+ HP- E85? My only point is that even with Meth port injection, there are several more things to consider. Sharing with this...

Hotter or colder has to do with the average expected temperature of the plug. It doesn't have anything to do with spark energy so it won't have any impact on MPG. A plug should be hot enough to burn off deposits and cold enough so as to not burn up the electrodes, insulators or cause...

While I appreciate new parts coming out and Whoosh is a good vendor, the stock turbo is the real problem for performance compared to exhaust and downpipes. If you're replacing the turbos, by all means, replace the downpipes as well. That'll maximize your gains and lower the amount of labor on...

Start a build thread and share details.

My untuned 4WD ST will bark the tires on take off if I turn off the the traction control and stability control. Yours should smoke the right rear!

Catastrophic- wrong thread dude! :)

Perhaps you could be more specific since you have first hand knowledge of a RWD platform? Did you completely disable traction control? Are you tuned? What RPM did you launch? That information is important. If you didn't disable the traction control, obviously, the ECU will go out of its way...
