Ah, the Jeremy Clarkson " More power" approach. But that makes sense because I spent a lot of time trying to put a leash on it rather than just letting it slide on and correct itself. Will have to practice more with that cuz it's not fair that my lack of driving ability, in certain areas, could effect the results.:ouch:
I really wouldn't worry about it, its not exactly a natural driving style for a lot of people. I would always recommend learning to drift as a way to improve your driving skills though, if you can learn to be comfortable in a car that is way beyond its limits then you can run closer to that limit while racing without fear 👍

Sounds like an excuse to go online with you boys and throw some cars around!:cheers:
 
@Lionheart2113 Thank you for that! I was having my dinner!:cheers:

Thanks for retesting!👍 Was it fun without the flat floor? :crazy:
No problem, I'm not going to penilize a tuner due my computer being stupid, or my stupidity. Now if it's their fault. Well that's a different story. *thinks back to the miatia challenge with the his typo on the ballast amount*
It was an exercise in futility and how brave I was in a corner. :lol:
I think @DaBomm4 would have had fun with it. Was very slidely.
 
I know don't want to deal the headacheof trying to teahc my wife how to use it. I'll just make a habit of rebooting more often, seems to solve the issues. If micropooft would just improvve the memory footprint clearing protocals this wouuld be a nul issue but they can't/wont do it.

Install more RAM, solves most windows related probles
 
My disclaimer...
**I’m not a negative person, so if there is any criticism it’s not meant to be an insult, and if my time is slower than what you have, then that’s fair enough. These are non bias opinions based on how I drive and should be taken with a grain of salt! I respect and appreciate the time the tuners have put into their tunes and I will try everything I can to get the most out of the tune itself.**
I tested these bad boys in a random order for 2 sets of 5 laps. Fastest times listed, and I will admit, that some times could have been a little quicker, but I was unable to put the entire lap together. ie up a couple of tenths in the first section, only to lose it in the 2nd or 3rd on that particular lap.

Snug on entry which lead to other issues throughout the corner, mainly power oversteer on exit. Looked cool, but killed my speed. Changed my arc down into the corner, with a little help of hand brake, and the rest of the corner worked itself out and was able to run a pretty respectable time.
Lap Time: 1:24.345
DC Score: 8.5

Bowtie-muscle
Good tune with a high level of comfort, except for the wheelie on the backstretch! Tapping the throttle coming out of 2nd gear corners helped keep the back in check since I can't short shift in automatic.
Lap Time: 1:24.276
DC Score: 8.5

Ridox2JZGTE
Not bad for a replica! Good entry with snug from center off and a snappy rear right at the very end. That's ok, it just reminds you that you are driving a Viper. A little adjustment on the LSD for my driving style and I would be more than happy with this tune.
Lap Time: 1:25.272
DC Score: 8.0

brian wolf
Good response on turn in with understeer from mid through exit and can snap at you just as you thought the corner was finished.
Lap Time: 1:24.382
DC Score: 8.5

Lionheart2113
Since this is my tune, I'll just list what I don't like about it. 2nd gear corners can catch you out, the back end is never consistent, and I probably should have added more mph for the backstretch.
Lap Time: 1:23.829
DC Score: 8.5

shaunm80
I ran this with TCS @ 0 and I got a better time, so I'll list the better one for the scoring. Biggest issue was rolling over onto the outside front on entry and then would drag the inside rear on exit. Not having the flat floor made it more difficult to control, and that's fair enough.
Lap Time: 1:27.030
DC Score: 6.5

Dolhaus
Solid tune. Typical snug on center and loose off, but it did have great response on turn in. Just never seemed to be able to put the power down smoothly to sling it around the track.
Lap Time: 1:25.561
DC Score: 8.0

Gino Caberlin
The rear end had sooo much grip that it just pushed the front end around. Just a little too difficult to get to turn. I wore out my e-brake button with this one trying to bring down the time.
Lap Time: 1:25.940
DC Score: 7.0

krenkme
This car loved to get any of the 4 wheels off the ground at any chance. Large amounts of oversteer during braking and sudden left to right movements. Some sections felt like being on ice. With all of that being said, it was fun to drive! So much concentration was needed, I don't think I blinked the entire time. And it did kill me on a few occasions...typical!!!
Lap Time: 1:26.655
DC Score: 7.0

Wicked oversteer! Anytime you thought about giving it throttle, it was halfway gone. Reminded me of my hyper dog on the end of his leash and he spotted a cat across the field. It wants to go!!!! Not being able to give it full throttle hurt, short shifting might help. But even though the rear lacked grip, the front had enough and was decent to drive on corner entry.
Lap Time: 1:25.270
DC Score: 7.5

MrGrado
This one has me a little confused. From the last chicane up through the 1st section, nothing could touch this tune. It was amazingly easy to point the car and it went. I felt like a dwarf among midgets, nothing but confidence. From the first tunnel turn on, it was a different story. It was tight through the center and pretty snappy loose on exit, more so on the lower speed corners. Going from the video, I think MrGrado doesn't use 1st or 2nd gear and unfortunately I was forced to.

xande1959
This is the tune to beat boys and girls. This car did what you asked it to, except for the extremely long wheelie on the backstretch! If you hit your marks, I strongly believe we have our winner...if you don't, this car will skate around on top of the track and hurt you. Classic risk vs. reward. Nicely done!
Lap Time: 1:23.739
DC Score: 9.5

oppositelock
I liked this tune, it was a bit snug going through the center, but nothing drastic. The only bad thing for me was trusting the rear end, it had a tendency to give a snappy loose exit when you weren't expecting it. Should have gotten under 1:24.000, but ran out of laps.
Lap Time: 1:24.060
DC Score: 9.0

Motor City Hami
The first set of laps, I was struggling with this tune. It had understeer and the front felt a little weird. Then I'd like to think I figured it out. This car does not like to be held down in the turns with my driving style. On the wider turns, I moved my line up 1-1/2 lanes and this car came to life. With more confidence through the center and a great launch out of the turn, I saw the lap times drop.
Lap Time: 1:24.487
DC Score: 8.5

DaBomm4
Tight on entry and loose on exit. Not having the flat floor really hurt my time, but the tune is not bad. It seems that any tunes without the flat floor always seemed to dance about on top of the track and never really got down into it.
Lap Time: 1:26.747
DC Score: 7.5

I wanted to thank the tuners again for their time and a thumbs up to our host @Otaliema for putting this together.
I'm wondering if there should be a non-flat floor category...there were 3 or so tunes without and the times showed it?!?

@Lionheart2113
. Thanks friend really surprised with that time, my best lap was 1:24. ***
congratulate you for driving it.:cheers:👍:gtpflag:

I think @DaBomm4 would have had fun with it. Was very slidely.
So, I should try no flat floors on @brian wolf car? I don't mind some controllable sliding so might be fun.
You could dual boot Linux and Windows, I never took the time to grasp Linux but I agree that the next gen OS doesn't work for us oldies. I have 3 almost working computers each with an issue, I can use one except internet doesn't work, right next to my rig so I can drive and take notes.
 
@DaBomm4 take the flat floor off any car that has it and hang on! Hehe
No it was under steer prone and so light on the front wheels that a slide was not really controllable
 
i should be done tonight, i seem to be a few 10ths behind everyone else on some of these tunes. My eyes kept getting bigger as everyone said that @Otaliema car kept having over steer when I felt the opposite was true. I think i'm gonna love some of these "drifting" setups. could get interesting...
You and everyone else is correct my car has under steer and oversteer, if your on the gas it's oversteer if it's off the gas it's under steer
 
All tunes tested. I know which are my favourites and some that are almost perfect but I don't know which ones I'll keep using.

I have posted a simple tweaked version for Trial Mountain ( suspension, LSD and brake balance ) Let me know if it's better than the entry here :D

Notes :
This is FITT Challenge - Viper Strike version with high camber, a bit added weight and NO OIL Change to fit with the regulations :D

I started building the replica recently, helping another member giving tips on tuning a replica. I got curious and build one myself. This particular replica is flat floor version with considerable more grip from front and rear downforce.

The Viper GT3R has ( unrestricted ) 680HP and 640 torque, while in GT6 I have a slightly higher torque at 649 ( closest I can get ) with NO Oil Change

For suspension, I tuned the car for easier turn in, while remain as stable as possible, springs are quite stiff at 16k/14k. ARB and damper setup to give the best possible mechanical grip from mid to exit and to work together with the added flat floor + rear diffuser. High Camber setup has been implemented for this FITT version.

LSD is 2 way as usual for cars fitted with racing tires, medium preload to reduce the car handling changes during entry transition to mid corner, while high locking rate to make the most of the massive torque, some throttle control is required on low speed exit.

Gearing uses ratio from XTRAC 416 instead, as 427D ratio has too close 5th and 6th. The gearing is well suited for the car, giving good spread and good acceleration on all gears.

I tuned and tested at Tsukuba, Brands Hatch GP, Trial Mountain and Silverstone GP.

At Trial Mountain, it easily lap in low 1:25s range on SS tire.

This version has updated suspension, brake balance and LSD for Trial Mountain ( bumps and elevation changes )


ENJOY :cheers:




Mainly changes on ride height for the bumps and elevation, camber also reduced to reflect the new ride height, front toe has been set for cambered turns and better turn in. LSD initial has been lowered to make the car more responsive, especially when hitting bumps or one of the wheel off the ground :P This should allow better composure when the rear slides, the brake balance has been increased at 4/5, not sure if it will work well on ABS 1, but it does work fine on ABS 0 ( for me at least ) :P

Some new pictures with flames and angles :cheers:

Yeah, I'll certainly give it a try.
 
Flat floor and ballast to the rear and mine is one of the few that don't lift???:confused:
I played around with rear ballast and it made the nose lift less over the rise on the back straight for some reason, it still felt vague in the corners with my setup though.
 
One thing I noticed was that if you were running any rear aero (wing/flat floor) you needed to put ballast in the nose to stop the front end lifting.
Agreed, I think it's a speed thing. The flat floor lets you enter the straight at a higher rate of speed.

Flat floor and ballast to the rear and mine is one of the few that don't lift???:confused:
Your car has a lower top end by about 15-20 km/h than everyone else in this challenge. Your car is redlineing at the bump while everyone else is still acceleration and going faster. I've noticed on runs that I don't make the turn right and hit the bump at 255 km/h or less I don't get much lift from any car, if i'm going 256 km/h or more I will lift all the way down the hill till i let off, or tap the brakes.

I'll have to adjust the final on mine a bit and see if I don't have wings!

Its a speed thing for sure but its more the faster you go the heavier the rear of the car gets with aero. A 50:50 static weight distribution when going at 100mph is probably more like 46:54 due to the wing pushing down on the back, this makes high speed entry difficult because the front tyres can't generate enough force. Putting ballast in the nose addresses this issue to some degree but how effective it is depends on where your car likes to sit distribution wise.

💡
Mine might just be that screwed up, that I've confused it!
I might just have to take yours for a spin and see how it works
