Hey guys, so wanted to talk about build. Almost everyone says start with the handling: arb, springs, weight etc.
But what to do with left over pi?
I favour accel over top speed, is there certain engine upgrades that people use that are just better? Like cams are often shunned for their expensive pi but what upgrades are preferred? Could anyone explain the effect that parts have in game or are they all pretty similar just adding hp and torque. I know some parts will add weight like oil nd cooling and intercoolers which I beleive is why they sometimes affect pi negatively, and some parts change distribution, im just looking for parts to look at first when doing a build (after handling is upgraded of course)
Two good upgrades to look at are the superchargers. The Centrifugal Supercharger adds torque exponentially as the RPMs increase so you get a little bit less torque than you normally do at the low end of the motor but you get way more from about 1/3 and up. The Positive Displacement Supercharger adds torque linearly so you get an increase across the entire RPM band but it’s not as high in the upper range.
Both superchargers will help you with acceleration all around.
After this, as PI permits, upgrade the supercharger is you can as high as you can. Then get a displacement upgrade as high as you can, the added displacement increases your power and importantly your torque and acceleration with (I believe, I’m away from the console right now) a weight reduction.
Some upgrades I know to stay away from would be the oil and the intercooler as they don’t add much power or torque but they do add weight (I don’t know if this applies when playing simulation damage). Also don’t use the flywheel unless needed to lift the PI. The driveline or rims are a better choice. A lot of people have also told me to avoid the clutch if necessary, but I think that’s up to you and that it depends on the car really. What kind of car is it? How old is the car? Will the clutch help it or is it inconsequential? I rarely use it unless I have a few PI points left and nowhere else to get them.
I’ll let more experienced and knowledgeable community members assist you further as beyond this I don’t know how much help I can be.
I hope this helps a bit.
Thanks for the reply. I’d heard a lot about the suoerchargers but never knew why they were used, I’ve put them in before but only cos they genarally have a nice smooth line as opposed to the peak of turbos, makes it easier for me to control my throttle I find. Thanks for the info
What did you mean by whether it applies with simulation damage? Does having it on simulation affect something that I don’t know about?
Well, oil, cooling, and the intercooler are typically used to help maintain a lower engine temperature right? I you add turbos to increase your power you tend to increase the amount of heat and stress within the engine and you need a way to maintain an adequate temperature. This is done using these upgrades but it does add a couple pounds of weight. When playing cosmetic damage, you can drive the motor in the red for an entire lap and nothing happens. On simulation damage this will begin to cause damage. I only play cosmetic so I don’t know how this would affect the car if it’s taken into consideration at all. If you play cosmetic don’t worry about it.
Turbos add a lot of power, but because they work off the exhaust gas they usually don’t kick in for a bit until enough initial pressure has been built up to spin the impeller which then builds more pressure and increases the engines output. Waiting for the build in initial pressure results in turbo lag. Some turbo cars have horrible lag, like my old Audi A6, while some mask it well and seem to have almost no lag at all, like the new Ferrari California T, and everything in between. When the car wasn’t built with this in mind, it will usually have turbo lag, especially if the turbo pressure is pretty high. In the game, they give you a large horsepower and torque upgrade but they do have this lag and if you use them, you want to set up the car tune to ensure you stay above the plateau as much as possible.
Superchargers run off of the engine RPM because they are linked to the engine crankshaft. They provide a[n almost] linear increase in power. As I said, the centrifugal cause an initial drop in torque but the torque curve is affected exponentially whereas the positive displacement method provides a linear increase across the powerband. Choose whichever supports your driving style and it will help you with acceleration.
For someone who claims to not be a pro you sure seem knowledgeable haha. Thanks for the info. I’m itching to get back on the box now but have to spend time with girl 
I know how some of this stuff works, and I know what to do in the broad sense. After that, it’s a bit sketchy. I’ve done a lot of reading of stuff on the forums, and youtube videos, and the likes. You’d also be surprised what you can learn by reading the scrolling box in the game though that really explains everything in terms of oversteer and understeer and there is much, much more to it than that.
I agree on the scrolling box, it served as a great learning source to begin with, and contnues to serve as a ggood refresher when Im trying to remember which way to move a dial haha. Except in the case of brake bias, suprised they havent fixed that yet cos its all sorts of backwards.
There are lots of ways to get accel with all the different motors out there. Simple way to explain motor upgrades
Centrifugal supercharger, race exhaust are the first 2 that I will put in. After that I will be looking at what gives the most power and torque for the pi. Sometimes it’s displacement, ignition, pistons but u just have to find the best choices. Also by adding one of them could change the pi and power gains of another so switching parts around is always recommended.
Also if you are putting in a sport transmission and your top speed doesn’t improve drastically you are just wasting pi you could be using for power.
