Hey everyone,
I'm coming off the rather arduous process of having my 19GT A10 engine replaced after only 4k miles ( 2000 boosted miles ) BUT only 38 miles of Stage 2 level power and only the second 0-80 smash it blew on the shift.
No judgement should be passed on the vendor or its tune I so happened to be logging the first hits and its was dead on commanded AFR, timing was normal no knock...clean then all of a sudden on the second hit after coasting and cooling down it pulled fine again and when it shifted ( tvs so it had full boost on shift) full KR retard I felt it let out and when I come to the next stop misfires which eventually led to the diagnosis of loss of 3,7, and 8 cylinders....
Where the old engine was one of the worse case copies with the tick starting at 366 miles, tip in and decel rattle along with 2k rattle...everything was checked by Ford and oil analysis done before installation of the supercharger, possibly checked to early to show damage.
The new engine is a totally different experience, it doesnt sound like a Cummings diesel at drive thru's, it sounds SO much more quite overall that its striking how loud I didnt realize the old one was. It's now at 800 miles with just perfection in terms of zero tick knock rattle and overall quietness....
It's getting close to time to do my first WOT logs. Having had such bad luck initially followed by what I feel like is a radically better long block ( build date May29th 2019), I really want to give it, it's best chance at it's best life lol.....
I was apart of the new engine fire from day one logging first start and my first drive no one has been in it...I can conclude the gas was good that was in the car when the first engine failed as logging showed in high load, low rpm scenarios it was constantly allowing timing increases over the stock map NOT retard...like well over....that trend has carried on with each subsequent tank. I have been using the same fuel in boosted cars from same station for 6 years....
So on the precipice of my first WOTs with what appears to be an exceptional copy of the Gen 3 Coyote, my mind wonders back to what happened to the first. Said Vendor has others at this boost level and spent a 1000hrs nailing a tune to be conservative and carb compliant. We tried to inspect the cats while the engine was out but vision was occluded by screens ect...I certainly detect no restriction but how much is to much flow and heat to expect from stock cats?
I mean 800 flywheel on 93 at 13 plus psi thru stock cats could THEY have backed up, especially in summer, and increased EGTs, what temps do they melt? Is anyone running near 700 wheel with the full stock exhaust including cats?
I dont care ANY about being louder, making more power ect I DO care about evacuating heat by having a free flowing exhaust protecting my cylinders....I read horror stories of gasing out with cat deletes...if anyone has any FI input such as much 800hp car has lived 20k with stock exhaust ect please chime in....if someone has any insight into why some people smell no difference and others say they wreak of fuel after driving around?
I am looking at the MAK Cat Delete possibly in the 3 inch to a 3inch H pipe with the stock mufflers...one thing I like about them is it seems if you buy the extra flange and weld it to the cat you cut off, you can replace the cats back on the car if you get gassed down.....
I want the quietest care that will flow enough with my system to not back up and hurt my new engine, I dont care about being loud or making more power....or ET....I need a few months to enjoy the car after my trials....
Thanks
