I guess I just know how to antagonize people really well LOL. I have a supercharged 928S4 Porsche and have had many other toys over the years and became good at getting people to want to race. I had a local with a blown 5.0 mustang years ago that would never race my Shelby Charger that runs 28PSI boost. I kept trying and trying and one day, he came up beside me, he mumbled something and I yelled over "you get the mulching attachment with that piece of doo doo when you bought it!" The race was now on after months and he lost to a 4 banger.
I've driven the ecoboosts and you're right- if you brake torque it, they launch well. The problem is that when you go just a little too far, you spin a rear wheel and the traction control kills the throttle. If you disable the traction control, you just make a ton of tire smoke. This is the same problem with the Hemi Chargers- the traction control kills you. Even if you turn it off, it will still pull throttle away after spinning.
I've owned a good number of fast things, but the most fun was certainly not the most fast. It was a 1989 XJ 4.0 automatic with a Paxton supercharger. I've punked more people with that XJ that you could ever imagine. It made 318HP at the rear wheels. IT doesn' t sound like much today, but in the mid 90's it did ripped apart just about any mustang, camaro and even 'vettes. My problem with that was the launch, but some rear leaf spring trickery, and a single torque arm (similar to the 80's camaros) solved that issue.
My latest one is my 06 Cummins Ram 4x4 dually. Just did a 708HP pull on the new engine and am out of fuel. Gotta go to dual CP3s now and I'm also going to do a HE451 VGT turbo (from an ISX) with a Steed controller. The existing 66mm turbo takes a while to spool and gives me WAY too much smoke...and I HATE black smoke. The VGT should be able to close off enough to give me several PSI at idle from what I've seen on another 5.9 with a similar conversion. I'm currently making 65 PSI and hope to get the same from the VGT, depending on what trim the compressor wheel is. I use a TST PowerMax PDA for fuel control and also have some other changes in the ECM via EFILive. Surprised a guy in a 360 Modena back in September who thought he was going to get ahead of me before the two lanes merged into one...and I didn't lift for the radius in the road afterwards. Love the dual wheel traction. I'll never own another single wheel pickup, nor a gasoline one. And I still manage to get nearly 17MPG around town. After the CP3 and turbo change, I'm targeting 750HP and that's it. I'm done. I don't feel like breaking it again. I can't blame the failure on power though. It was a faulty #6 injector that stuck open on the highway at 85 MPH. When it happens, it's over quicker than you can imagine and #6 piston had no more upper ring lands left. Moral of this: if you have a 5.9 or 6.7 common rail, change you injectors if you're past 125,000 miles. You'll be glad you spend the money to do it.
That is a cool list of cars you have had.
Yeah you need to launch the ecoboosts in 4x4. The Lariat and up trims have an AWD mode which is what I usually use since I dont have to worry about binding. Its full time AWD, fully variable of 0:100 to 50:50 on the fly and works pretty well. My truck will never be that quick though as it weighs 6200 lbs empty. The new aluminum ones move though. A guy ran a 13.75 in a bone stock 2017 crew cab ecoboost, and another guy ran a 13.36 or something in a stock RCSB 5.0. Throw just a tune on the new ecoboost and these guys are running mid to low 12's. Its insane.
Why not a compound kit on the Cummins? Its so easy to do on that motor being an Inline 6 and it seems like there is very little downside? I ask because I secretly want to do this with my Liberty one day
Stack a GTX2860 or EFR6258 right after a stock sized unit and run 35-40 psi with both turbos only having to run a 2:1 pressure ratio.
