Turbo

Question, is the power loss from a stage 5 turbo much of a significant drop from the stage 4? In other words, @ Nurburgring, would I lap faster with a stg 5 or a stg 4 (can i top out at the straight at a decent speed)?

Suspension

Yes, most of us know that there are advantages and disadvantages to a stiff ride, but is the Ultra-Stiff ride from an "Original Suspension" (as in the 1 you can purchase for select vehicles) better to equip on your vehicle than a racing suspension? I guess it all depends on the track your riding over and user preference but i would still like to hear some opinions...

Well, because the ring has both long straights and tight turns, that's difficult to say. Original turbo's biggest advantage is that decreases lag at low rpm, having eventually better acceleration. I don't think 5 or 10 or even 30 hp would make big differences, so I say original is better in this case. 💡
 
I figured...:dopey:

How about suspension wise? I mean I know I can get smoother weight transfers with the sofer spring rates but theres nothing like subdoing it altogether with the original suspension:idea:
 
With the racing suspension you can adjust ride height from e.g 70-90. On the same car, you can adjust the original from 64-97. If you wanna race in Motegi whose road is very smooth and well-made, making the ride height as low as possible is useful, and stiffening the springs is useful, too. If your choices for the ride height for example are between 70-90 (racing suspension) then buying an original I think is useless.

---> In other words, original suspension is useful only when you want to make adjustments that the racing suspension can't reach. <---
 
Racing suspension also allows you to adjust both the damper bound and rebound individually, again a rather large plus point for most tracks. It can even help with the very smooth tracks, if you want to ride the curbs.

In regards to the Original (St.5) turbo, it decreases your overall peak horsepower, but it widens the powerband significantly. You may not have as much power on tap, but you'll have it for a much broader rev range than with a St.4. It's like having a St.2 with St.3+ power and torque!

The original suspension is plenty good for most normal racing, but (as Scaff pointed out) if you really want to customize your ride, you'll need to get the full Racing Suspension. It allows you to tune your ride a little more finely, giving it the slight edge over the Original.

Indeed. As usual, I'll bring a WRS Example: Week 85. It was a battle between any road-Evo and road-STI, which took place on Seattle. All cars were equipable with original suspensions, yet almost all picked a racing one, for this very reason. Seattle is a track where you don't need low heights (less than 100mm is not recommended), and where soft suspensions and sophisticated dampers (to increase traction during kerb-riding, jumps and regular turns) are needed - which is why the Racing-suspension was picked.

In most cars. A select few have a higher peak power output with the Original Turbo Kit, which more or less makes the decision for you :)

But there is almost no situation where a Stage Four turbocharger is better - even for 300mph runs, I use the Original kit. The powerband's versatility more than makes up for the bit of peak power you might lose, anywhere you happen to be. Even with worn tyres, the Original kit will fare better, because your tyres won't suddenly be assaulted with a mountain of torque and power when the turbo starts to take effect, whereas with the Stage Four they would be. :p

In regards to high speed tuning, it's around 50/50 as to which turbo I use, with the the stage 4 possibly having a slight margin.

But then, I don't know much about high speed tuning... :dunce:

I will point out though, that in my experience, the Original Turbo almost always has a higher peak torque output, and generally tends to yield better laptimes under normal tuning.

As for the suspension, it really just depends on the settings you wan't to use. for the most part, the setting ranges are quite similar, so either will do. For high speed tuning, I use the Racing suspension almost exclusively, as it allows for softer settings, not to mention that it allows the damper bound and rebound to be set independantly. 👍

Sometime even with lower max hp, stage 5 turbo can give better time because it has better low to midrange hp.

I prefer racing suspension because I don't like riding ultra stiff spring with no possible way to equip damper at the matching stiffness.

Oh really... :sly: You learn something new every day! I've always used Original turbo, but then again the only road cars I've used are Skylines, all of which have a higher output with the Original turbocharger.

I found the cars tended to drive a bit better with the St5 turbos. A lot of people look at power and overlook torque. As MasterStorm mentions about peak torque, it is just as important as peak power. The more torque your engine has lower in the rev range, the harder it will accelerate under throttle. Hybrid turbos (probably what St5 was designed to emulate) are built to give lower boost threshold, less lag and more midrange power/torque.

I found that a car with Stage 5 turbo had better response over Stage 4, especially on more technical tracks where your engine revs were up and down.

I really havent stuffed around with Original suspension much, save to say that I prefer the damper adjustments on Racing Suspension.

I thought that St.5 Turbos were designed to emulate "twincharged" vehicles?

(For those who aren't familiar with twincharging.... A car which possesses both a turbo for high RPM kick and a supercharger which aids in low-mid range boost)
 
Lotus, nope, it's just simulating differend kind of turbocharger that has lighter rotating parts (bit like ceramic turbos, but stronger), or then a turbocharger that has VTG (variable turbo geometry).

True. That and mix/matching compressors and turbines to give better boost characteristics. A smaller, lighter turbine requires less exhaust flow to power, so boost threshold and lag can be reduced. The downside is that the smaller turbines can't handle the same amount of sheer gas flow as a bigger turbine, so peak boost and high end power can be sacrificed somewhat. Here is an example of a hybrid turbo.
 
You learn something knew everyday

I, however learn something new every quarter-to half hour :dunce:

Someone once told me: The day you stop learning is the day you die...

Hybrids are but one way of maximising output - I would dearly love to see the option of 'twincharging' in GT5. Imagine taking a Viper and 'twin-turbo-supercharging' the thing... You could put turbos on it bigger than a football and use the supercharger to give low down boost (and cut down on threshold/lag at the same time). I don't know about you, but that would put a smile on my dial any day of the week... and twice on Sunday! :sly:

Here's an interestingly done twincharged WRX
