Hm thinking about it, it would be good if the mods made a sticky of track times around circuits-with your car mods.

Anyways guys, i'm heading to thill this weekend...what are some of your times/with what mods ?

I have lapped around thill in the rain in the 2:11-2:15's with a rental 350Z...with the porsche i'm hoping to get sub 2:00's..

What are some of your times ?

TIA

A 996 cup car with a good driver and slicks can do 1:54:xx with the full course. A top spec miata competitor does 2:08 (full course). A street GT3 on sports cup with a decent driver will be around 2:02.

Assuming your TT is stock from a weight point of view, I would expect a time around 2:02. sub 2:00 will be difficult. Conering speed is very important.

In which config ? 5A/5B or bypass ?
Either way, you're mucho faster than I am. With my stock x50 on PS2s, I was lapping around 2'17" in the 5A/5B config. I am not surprised that a skilled driver could beat this in a 350Z, but sub-2'00 would have you smoke any of the Nasa time trials participants.

 

The bypass is usually worth 1 to 2s depending on the car.

I like the sticky idea, with the number of guys that track their car we could do this and the same in the GT3 forum and compare (I.E. how many mods it takes to beat the GT3). OR maybe just one collective thread with all the times.

 

Thanks for the valuable information..
Hmm yikes...i have a set of fresh PS2s in the front with bridgestones in the rear..i opted for this so i can get more oversteer then understeer...thats my cure for the car untill i get a suspension on it.

Hmm well my friend broke it down to me like this:
2:11 best time with 350z in the rain
-3 secs in the dry
-1 sec faster in all corners -due to more power/better brakes/better suspension= 12 secs total
-2 secs- improved my driving ability

so he thinks i can do it 17 secs faster then i did with the Z... geez i dont want to let him down but it seems freaken hard!

he believes i can touch 1:55's with my driving... thats blistering fast....i think i might dissapoint him


I'm not sure which configuration, i'll check and post back.

I think its a good idea, i'll try to make our turbo owners proud this weekend

 

I think the dry+better car will net you 1 sec in each corner. 1.55's is FLYING if the cup cars are doing 1.54's. However I maintained 1 second on a pretty fast Cup car at Road Atlanta on street tires so it's possible. But if you are talking about a very good cup car driver and car, I have to say that's one TALL order. But good luck, and dont get obsessed with your lap times because you will start pushing too hard and slow yourself down.

 

That's the assumption I am skeptical about. Power is not gonna help in corners, and I am really not sure that a 350Z has such bad brakes or suspension compared to a stock TT. The 350Z is not light, but it's a sound car. Anyhow, good luck and remember, having good fun is worth a lot more than a clocking a time ... Thunderhill is not Infineon, but that there are still creative ways to total a car there.

 

I completely agree. Cornering speed is all about grip. Grip is all about weight (lighter is better). Aero can help but only in the high speed corners (like 1 and 8 at thill). You need to be over 100mph. To illustrate, and looking at data acquisition, in slow corners, my miata is about as fast, as my cup car. The cup car is on slicks, the miata is on Toto RA1. However, the miata is only 2300# with driver while the cup is between 2800 and 2900 with driver.

I have seen many cars totalled at thill. When tracks don't have walls, the risk of rolling is much higher. Usually wall contact occurs at the exit of 15 and on the inside of the esses (12 13)

 

obviously back from the bodyshop,
I watched them bring it back to life

 

I wasn't being timed.....but I hit 132 - 133 on the main straight last year and could have gone a little faster but didn't want to get on the brakes that hard at the end...let up a sec or two earlier than I could have.....I'll be curious to hear how fast you get it up to.....(for comparision )

Brian buddy, i have a gift i got you for the awesome SA you are -- i'll stop by and give it to you Friday !




Thanks everyone for the replies. In the rental 350Z i took turn 8 at about 110mph plus, I do not know why TC was on- that particular time(maybe my knee hit it on?), but that caused me to go for a VERY nice series of spins- it made me back off the throttle there for a few laps and not take it at WOT, before i regain confidence.

 

hmm on the rental 350z's i can manage to kill the break pads in less then 1 session... so usually when i rent them i get 1 and half sessions and then i have to pack it home.

Usually i go on untill they wont respond at all.. i know im a bit physo for taking risk but i take it as 'practice' so i can prepare myself for situations like that, and put myself mentaly at the limit. For example once at laguan seca i was going about 135mph down the straight about to hit on the breaks on the TT, and they didnt respond, instead of panicing i started pumping the breaks like crazy...and i managed to stop the car and complete my lap ...i like to put myself in bad situations so when it really happens (like with the tt) i know how to react.

 

Yes it is, i dont think i can achive it, at least not on street tires, theirs some turns on Thill that you need tons of mechanical grip, which are off camber and i dont think the TT is suitable for them. I'll try my best though, and of course have fun!

Hmm the only thing i will be removing is the spare tire, other then that it will be staying stock.

As of now i'm thinking of running 32 psi in the front with 36 in the rear, give myself more front mechanical grip so i wont induce as much understeer.


I'll report back to you sir, i think i will be hititng about that same speed, with the 350z i was seeing about 120 before getting on the breaks.

 

in a turbo, you should easily hit 140+ before braking for T1.

in any street car, unless SERIOUSLY modded, it's very hard to go sub 2 min at TH (i am talking about cyclone times). and there are only a handful of ppl who aren't pro or club racers who can approach that time.

i seriously doubt a non slick shod stock 350 will ever come close to 2:00 with cylone. if it gets to 2:05, you are one hell of a driver and you should stop tracking and start racing.

1:55 in a non slick turbo is amazingly fast. in fact a 2:00 cyclone lap in a TT with mpsc would scare quite a few club racers.
