Velocity AP power package ?

Velocity AP power package ?
Hey guys sorry to make a new thread but I am very interested in a power package that VAP is offering and would like to know if there's anything I should know before installing these parts (DP, crank and SC pulley , and tune ) . I have a 2016 ftype R got new motor put in about a month ago under factory warranty because it locked on me while racing in Mexico 😅 I understand I may additionally need intercooler , does anyone have recommendations ?

Start by removing engine cover - it traps heat.
If you are racing, especially in 100+ degree weather, then I recommend against tuning. All tunes increase boost, this is how you get extra power. Increased boost also results in more heat. My experiences is that F-type in racing conditions is limited by cooling - what killed your old engine is likely heat-related. Yes, you will get more power with VAP tune, but you will also make heat soak much worse.
At the very least you need to upgrade intercooler and install a high-flow intercooler pump (you need to do both!). I know Eurotoys sells intercooler that fits F-type and I know high-flow pump exists for XKR, but I am not sure if it is direct bolt-on for F-type.

VelocityAP power package performs very well without additional cooling! Where do you guys come up with this misinformation!?!

So is there a lot of people running downpipes , pulleys, and tune without intercooler upgrade ? I mean I may still get intercooler because I understand it definitely does help but if it's not necessary I may hold off on it a lil longer

I recall you mentioned that you race in Mexico, how hot is your typical track day? How long and how fast is you lap?
If all you do is stoplight "race", you don't need it. If you are serious about not spending lots of your precious track time doing cooldown laps or sitting in the pits with hood up, then you need to upgrade.
For me, I usually have 2 hour open track time, I like to split it to 45 min - rest - 45 min. On a very hot day my stock car can start pulling timing if I ride it all-out. This is V6S rear wheel drive, where I have larger oil pan than AWD and the same engine cooling system as V8, so I have more cooling relative to engine displacement than V8 would have. I know V6 stock runs slightly higher boost than V8 stock tune, but I also proportionally have more cooling.

If you don't race, you can get away without intercooler upgrade. It takes me about 10 minutes driving flat-out (mostly WOT) to heat soak at ~110F degrees ambient with a stock setup, my best guess that with a tune it would be happening around 6-7 minutes range. It never happens at 90F and below.

That's obviously not a true statement. If that was the case, no one would ever make more power by advancing timing or adjusting a carburetor. If you wanted to tune your car for increased octane at stock boost levels, you'd make more power. Hell, there are plenty of naturally aspirated engines out there that benefit from tunes, and they aren't getting anymore air into the engine...

As above mentioned, only tunes do nothing with boost. You really should learn a bit more before arguing with your tone about specific topic.

both arguments about power increase are possible
1] increasing or at least, optimizing power with just a tune, and no pulley or waste gate control on a boosted car? absolutely possible. Not much, but possible.
2] most, but not all ECU tunes for this car include a pulley. Some don't
I have asked three times, now--have received no answer from the thread starter, and I think the most important question that NO one is compelling Firesandftype923 to answer is this: what the F happened to his motor? How, and why? This should be cause for alarm, I would think. Could effect all of us, at some point.

Alright, so what parts are different? Post the list to show that my statement is wrong: "This is V6S rear wheel drive, where I have larger oil pan than AWD and the same engine cooling system as V8"
For example, radiator is T2R18423 and it is the same part for 3.0 and 5.0L engines.

Carburetor tweaking has very little in common with injection system, most of carburetor tweaks are about making sure adequate fuel across all RPMs (it is an analog system), for a modern injected engines this is a solved problem as you can control individual injectors.

I also think many posters here misunderstand what pulley mod does - it brings peak supercharger boost lower into RPM range (at a trade off of over-revving supercharger near redline). Both stock and with pulley tunes make more power by fiddling with boost controller. They rely on thermal safety maps to prevent bad stuff from happening as intercooler is not up to the task of continuously operate at these boost levels. Fiddling with timing is typically small gain (unless something is really off when you started) and comes with trade offs in idle quality, anything most than small tweaks requires different cams.

Now now... don't try to make it seem like i'm being hyper critical. You said "universal rule". This is how people on the internet trying to educate themselves learn the wrong thing based on bad information.
