GT4 Tuning - An interesting little test - Volunteers needed

[Der Alta]

Just something I noticed (sorry if everyone already new this, I didnt) I dont know if this happens on every car or if its just on this car, but if you give this car all the power mods including the supercharger but excluding the Racing Chip, the car gets 268BHP, then when you add the racing chip it reduces the cars power down to 228BHP.

ANd had you read the entire thread, you'd already know we've covered this.💡

I missed it, sorry

Im finished comparing these setups aswell, one is definately alot faster than the other.

Edited by moderator - please don't screw this up. It's important that it be impartial and blind. Thanks.

I´m really excited to see how this turns out. I have followed the discussion between the two combatants for a long time, and I feel that I probably should have been a tester, but at the same time...I´m biased...

I did the test yesterday afternoon, and immediately noticed (rather large) differences between both setups.

Is the thread for our results up yet?

I've PM'd DA to get his opinion on how best to deal with the results in a manner that will keep things fair.

Hope to have an answer for you ASAP, I can assure you I'm as eager to see results as you.

sorry I haven't posted lately. just been busy with work n stuff. but I did get a chance to test one of the setups...and, I'm quite impressed. won't say which yet tho. hehehe, ooo the anticipation just keeps rising doesn't it? lolz, kk. I'll have results asap. thanks!

I've tested one setup so far (not telling which one), and I have to say, as long as you can control the urge to floor the throttle (dangerous even in 4th), it's so quick... 1'23s so far, I reckon I could break into the 1'22. This car just handles so... Quick. No understeer, clean braking, turn-in, and out of there.

 

[Sharky.]

One setup I clocked a 1'21, the other a 1'24

Oh dear.

I ran the other setup about 3 hours ago, and I've spent the last hour or so sat in this forum trying to think how I could post my initial thoughts after running both setups.

I'm sorry, but I'm quite disappointed in both setups. Sure one setup is better than the other, but I was expecting a lot more from you guys regardless of the gap between the two setups. I won’t go into detail as I will save that for my write up later, but I have to say that I will find it very hard to give credit to any of the setups.

Sorry again guys, but it had to be said

Here are the lap times for both setups so far:

1’18.9??
1’21.1??

Still more time to come off for each setup. I will have another go later.

 

[Sharky.]

I actually agree with Sphinx in that neither setup was as good as I expected. :|

You and Ron are the only one with credits to say that, seeing that your superior setup was a major factor (at least a factor) that helped you win by over a second on the WRS 74... Any chance you might post that one after all, or after the discussion?

Well I don't want to get into that area because it wouldn't be the right thing to do. I'm not part of this challenge, I'm simply here to drive and give my opinion on the setups provided by others. 👍

Which is more than greatly appreciated, I've always been a great believer that settings are very difficult to transfer from one driver to the next. What one person may love another may well hate. Which for me is also part of this little experiment, so I look forward to the results no matter what the outcome.

In regard to WRS 74 I would advise against it being used as a straight comparison as it ran with R1 tyres rather than N3 (which is a huge difference) and the modified set-up for the exhaust, etc not only increases power output but also completely changes the cars power curve (for both bhp and torque). So while the car and track are actually the same, the real conditions are quite different.

Maybe one could look at it this way:

The driver who loves the setup is pulling 1'22 lap times, and the driver who hates it is pulling 1'18's. Ask the slower driver to lose 4 seconds off his 1'22 lap time and he would then learn to hate it. Ask the faster driver to slow down by 4 seconds per lap and he would then think it is a breeze and have no trouble with the car when doing so. 👍

 

[Der Alta]

Here's how we can work this our to make "blind" comparison. If you'd all like to PM me your results and evaluations, I'll post them up in a new thread. The beauty of this, is that while the set-ups are not known as to who's who's, They can still be assembled in Thread form. Thus allowing for open discussion. I don't think we'll be able to maintain the true ambiguity, as the true descriptions will undoubtedly reference the settings and thus giving it away to the original tuner.

However, I don't think it really has a severe consequence.

I also suppose that I could just never announce who's is who's and simply leave it as only the three of us knowing.

PM away guys, I'll post them as I get them.

Nope. Ask the still-Div3 guy to improve his skills. I'm not sure we're talking about the same setup, either. You're top-Div1, I'm low-Div2/high-Div3, so you can't expect the same laptimes. I push it to the same limits, but not to the same laptimes - and I don't have anything better to compare the car with.

 

[Sharky.]

PM with report on each setup sent.

I aplogise if I offended you, Gingiba. My comments weren't aimed at you my friend. 👍

Allow me to ask you this:

What is the limit? If you answer this correctly you should come back and say that you don't know. Now if you asked me what the limit is I would reply back to you and say that I also don't know. There are many drivers faster than I, but even that doesn't mean to say that they know what the limit is.

 

[alrivers]

what I meant by being quite impressed was that I was able to get the car sideways at extreme angles. but having tested only one of the setups, I still can't give a definite answer. I'll update later.

 

[DJ Baker]

Results submitted.

 

[niky]

Okay, I've only had probably five or six laps with each set-up, plus a reference run in a "stock" Caterham (no roll-cage, same power).

I'm a FWD driver, for the most part, and I haven't had much "seat time" in GT4 in the past month.

Initial reactions: Both set-ups are "touchier" than "stock", with a more aggressive turn-in and approach. The "stock" Caterham had shedloads of understeer at high speed, and its long gearing made it easier to lean upon.

I initially felt one set-up was more stable than the other, but as I adjusted my driving style, I kept pulling faster lap-times, and now the other one, despite feeling weird, initially, isn't half-bad (faster, at the moment). After about two dozen laps (spread over four sessions), I've got both down near 1:22 flat... lots of mistakes, lots of room for improvement. I'm not used to the entry-speeds and braking zones needed for a car this fast and this grippy on N3s.

Once I've gotten as fast as I think I can go, I'll PM my results to Der Alta.

 

[VTRacing]

I will pm my results in about 24 hours.

More testing to be done, I've had about 60km on one setup and about 130km on the other.

One setup definitely feels faster than the other, but having said that, on my baseline running I achieved a time with stock suspension only two tenths slower than my fastest with these setups.

*Devils Advocate Mode*

And in the real world most race engineers would give body parts for a 2/10ths a lap gain, over the course of a ten lap race that's a clear 2 seconds advantage. Look at it in F1 terms (say 60 laps) and that's 12 seconds. That sort of gain wins races.

*Devils Advocate Mode Off*

Of course this is GT4 and if you are racing against the AI it doesn't make a blind bit of difference on the whole.

[TheCracker]

As a none wheel/pedal, auto box user (offering me less throttle modulation and no choice of short-shifting) i have found that the gearing on both leaves me spinning the rears round most of the circuit - one set-up has me braking traction in 5th down the main straight. I've not been able to gather any meaningful lap times in the 20-30 laps i've done so far. I tried a few laps with TCS set at 1 and although i was immediately 2.5 seconds faster after 1 lap, i think even a low TCS setting compromises the LSD set-up work done by the two 'tuners'.

I certainly favour one set-up over the other. One feels more like a 'drift' set-up than a race set-up.

 

[Blake]

Results/Report submitted. I didn’t do too many miles, but for me there was a clear difference and my opinion was pretty much set in stone.

 

[Sphinx]

sorry for the delay, I'm just going to run a couple of laps in each car to refresh my memory and I'll get to writing the report.

 

[daan]

My report is in.

Do I sound like I know what I'm talking about, DA?

 

[Der Alta]

All the set-up reports submitted have been very good.

Well done gents. Now, if I can manage to get a few laps in on this myself.

 

[Tornado]

This seems like an interesting study that I would like to take part in.
