For the GT Academy Time Trial with the Nissan Skyline, I have been thinking about this. Is there a difference between:

A car which is stock and eligible for the set BHP

Or a car which is fully tuned, but power limited to the same set BHP.

Just wondering.
 
Depends on:
  • The car's torque curve before being limited.
  • The amount that the car is limited.
  • The car's gearing.
  • The car's weight.
  • The track design.
  • The race length (if set to be long enough that tire wear is a factor).


Generally though, despite how many people here drone on about how the engine limiter breaks the game balance, outside of a few specific cars (and the occasional lucky track/car choice) if you limit the car's power beyond 15% or so (though the percentage you can limit it without consequence increases as the base horsepower decreases) it will be slower at the same PP than a car that you did not do such to.

A car fully tuned, but power limited to the same set BHP is most likely faster than the first option. Despite being set at the same BHP, the fully tuned(but delimited) car is still equipped with all the upgrade parts(turbo kits, intake, exhaust, etc.) that improves its performance when comared to its stock counterpart.

Depends on some cars and how much you limit it however, many other factors to consider.
 
I've found that tuning a car up and then turning the car down is worse than just leaving it stock where it is.

Try this, tune a car up with some HP add ons, then turn it down until it matches it's stock PP. Note the HP, then remove those, reset it so that it's stock. You'll find you have more horse power stock.

It's weird but the game rates HP as worth more PP than it should, imo. In addition, I've found that weight is worth a lot less PP than HP is. So, if you're thinking of tuning a car up to match PP, always reduce the weight first. I know it's hard to think about, because the weight options are irreversible, and you can't really add that much weight back onto the car with the Ballast, but it works for me.

I hope that what I said is clear, but I can give examples if you want.

This happens because the Torque isn't adjusted properly when using the power limiter, and can end up with a lot more than what it would be stock, hence having less hp. Torque adds to pp as well.

eg, (scale of 1-10)

stock - hp 5, torque 4.
full tune - hp 8, torque 7.
Detuned - hp 3, torque 6

a detuned car has higher torque than a stock car and therefore will have to have less hp to match stock pp.

But which is better for which?
For example, is the one with higher torque better at tracks with lots of corners or less technical tracks?
 
For tracks with lots of corners and slower speeds, a detuned car would be better and cars with more torque will be able to put the power down coming out of a corner, where a car with higher hp would be better for higher speed tracks, to get faster top speeds and faster high speed acceleration. (100-200mph for example) But that's my grasp of what this is, i can't confirm for 100%, but this is also the reason the saying "hp sells cars, torque wins races" has come about, but that isn't always true.

For most circuits, you generally want them to be even so you have power and torque at your disposal (good top speed, good acceleration), rather than one or the other. (excellent top speed and shoddy acceleration and vice versa) Again, this is how I've grasped this concept, may not be solid.

I'm gonna test this to figure it out. It'll only be a straight line test, and I'll look at my ghost and compare.

I'm using the Dodge Viper SRT10 ACR '08 (because I was tuning it anyways).

It's fully tuned at 1000 HP, 1257 kg and 661 Performance Points. Torque: 847 ft-lb/5400rpm, 1000hp?6800rpm. 1.23kg/HP. I don't, however have a spoiler yet.

Lets remove everything removable that adds to PP.

Now we're at 792HP/6300rpm, 697ft-lb/5300rpm, and it still says 1.23kg/HP which makes no ****ing sense. It dropped to 634 PP, however. All settings are default, tranny, suspension, limiter, ballast and LSD, but Racing Softs.

It actually redlines at the end of the mile, but
1/4: 0:10.011
full mile: 0:24.503
0-60: 0:02.625
0-100: 0:05.121

Sweet. Now, lets add everything back but tune the engine power to match the PP. I added the ECU, supercharger, intake, manifold, exhaust, cat and headers back on. I had to go back to the transmission and reset it to default because the top speed changes sometimes.

It's now 753 hp/5000rpm, 824ft-lbs/4800rpms and 1.64kg/HP which is weird. I don't understand why it changed the weight/ power ratio but **** it, who cares. Back to 634 PP. Notice how this time around, I have WAY less HP but WAY more torque.

It redlined again at the end, however it performed completely better.
1/4: 0:09.938
Full mile: 0:24.438
0-60: 0:02.616
0-100: 0:05.007

G-Force remained constant.

Now, this tells us, imo, nothing about cornering, but for me, at least, but good luck with this. Lozzy, thanks for informing me, I'm glad to know this and don't feel bad about tuning up and limiting my cars now, lol
 
The RB26DETT engine has a very broad power curve stock.
I mostly use the power limiter on cars with very spiky power curves.
A car with a broad power curve is better left alone in my opinion.

A proper set of gear ratios are crucial though.
 
I always preferred to leave engines as stock as possible to keep more HP rather than torque. When racing against a ghost lap of a detuned set up, I generally find that the more stock engine with higher HP has better acceleration and top speed. It also helps if you tune the gears specifically to take advantage of the extra HP at higher revs, and the smoother power curve makes it easier to judge the throttle output on the exit of a corner.

I have been running all GTA seasonal TT with fully stock cars with only BB changes, for the R32 GTR, I tried to follow P1 ghost ( Lewis_Hamilton ).His car is way faster than my stock unmodified R32 - 300hp/1500kg/453pp. My best time so far is in 2:02.xxx, P1 is 1:58.2xx, around 4 seconds faster, I could only keep up on the 1st continuous right handers, P1 car left me for dust on the next left. For reference, my stock R32 best 1st sector 0:39.xxx, and 2nd sector 1:24.xxx. A 2:01.xxx lap time is possible with a perfect run on a stock R32.

Despite P1 car has only 3 more pp, it might also have been fully tuned - suspension, transmission, LSD, carbon drive shaft, twin plate clutch, semi race flywheel - all of those could make the car faster both on straight and corners.

Even both cars with the same power/weight/tires could perform differently.

Simple test : Run the stock R32 GTR at SSRX speed test, then put non PP upgrades - clutch, flywheel and carbon drive shaft, it will post better acceleration times. Put better gearing, and suspension, it will be even more faster.
