2018 + CJ = 500+ WHP

What he said, ^

Track guys run both driver and passenger side catch cans, spending most of the time above 5500 rpm for a 20-30min track session and you will need catch cans. The other reason we use them is because of the design of the PCV system, having the PCV ports at the front of the head means under heavy braking events on track the oil in the heads pools at the front of the valve cover right at the PCV port on the valve cover. Dive on the brakes and get right back on the throttle and oil can be ingested through the intake if a catch can is not present.

It's 2018 and the engine doesn't drain it back down properly?? :shrug: I don't do road racing so I'm a bit ignorant of this problem.

I was well aware of the problem on my '69 SS 396 and '85 5.0 but never imagined it could be a problem on these engines.

For daily use or the occasional drag or track use i wouldnt be concerned 1 bit not using one.

If you do not do road racing it will not be a problem, these engines move an insane amount of oil compared to an old school small block or big block. All the oil has to make its way back to the pan and that takes time, add in the pumping forces from the back side of the piston as it moves down and there is a lot of air moving through the block and oil journals. It is very normal for a road race engine to have modified PCV systems in order to deal with these issues. The date and time have little to do with the mechanical workings of the internal combustion engine, the materials have changed , the efficiency has increased but the principles have not changed much over time.

Ford deals with the issue by adding oil capacity to the engine, 8 qts compared to older engines using 5 to 6 qts so the sump does not run dry while the oil makes its way back to the pan. For road race use it is recommended to change the oil pan to one that is baffled and has a higher capacity of 10+ qts of oil.

These changes to the OEM design are done when you want to operate the engine outside of the OEM design criteria. They did not factor in the sustained g-forces encountered when a car is used for track duty. They design cars for how 99% of their buying public will use them not the 1% of us that use them on track. All things considered the modifications needed to make a very competent track car out of the Mustang are not that many, that hard, or that expensive.

The only reason 2018 mani is so cheap is because it retains the stock TB while CJ and GT350 requires separate TB.

Plus ford made 2018 out of very cheap plastic - I can see them broken all over the place. Super cheap means low quality as well.

Umm no broken CJs are very common also. And just the CJ mani is about 600 vs the 18 is like 300.

18 mani is about half at best + CJ TB and CIA though.

Black friday complete setups were selling last year for like 1500 everything minus tune.

the ten speed kind of makes manifold swaps a different ballgame...now we're only operating in a narrow band of power,at full throttle of course..so looking at power under the curve isn't quite as important as it used to be..i

My stock '17 GT make the ponies all the way too 7200 rpm. VCT tuning wakes those mannies up. But otherwise yeah.. E85 = Don't care.

Peak Hp and Power under the curve still matter and will always matter no matter if its an OHV engine like the Camaros or a DOHC engine like the Coyote or a diesel pickup.

The 10 speed means less rpm drop per gear change. The 10 speed shifts really fast and keeps the engine in the upper rpm longer because the rpm drops less between shifts.

It would be night as day difference to have a 10 speed in a car that makes alot of torque but say max rpm is like 6800 rpm vs say a NA high reving 8k rpm coyote build.

Where the engine makes peak hp and peak torque in the rpm rqnge will greatly change how the car feels.

If anything personally I think the transmission tuning and shift strategy will be even more important in a 10 speed vs a 6 speed auto.

Making the shift pattern hold a gear in certian rpm range before the next shit will make a massive difference too. Ex. tightening up the shift pattern or spreading out the shifts farther apart in the rpm range.

Think of it like a 1/8th mile setup vs say a standing mile setup the 1/8th mile will need either the trans to shift faster through the gears or end up getting through the 1/8th before going through all 10 gears.

The standing mile car would be better off letting the car spread its legs so to say and let the car ride out each gear through the rpm band instead of quickly getting to top gear and holding it. Kind of like starting out from a dead stop in 3rd with a manual car.

Adding even more to this itll be interesting to see once people start stalling the 10 speeds and see what kinds of gains that makes or if its even worth it or not.

But again power under the curve and peak power still very much matter.

I disagree and agree ,partially ,in a quarter mile situation your never going to be more than a few rpm out of peak power except for first, provided the tranny is tuned to the engine, but yeah I can see in half mile or mile races the the overdrive gearing will make under the curve power more important. depends on what your into
