Viper TA - 1:28:93 @ WSIR

[TheKosherStogie]

Went with Speed District today to WSIR. I'm heading up to Carmel, CA so only went for the morning session as I was eager to take my new car on track.


Car has DSC/Tractive/ViperExchange suspension which felt unreal! I haven't driven the car on stock suspension but this was really fantastic. Started it in stiff mode but was too stiff for wsir which is bumpy. Even soft could possibly be softer just for turn 8 which is choppy as hell if you're familiar with this track but my speeds through turn 8 were 134-136mph which is as fast as I've gone through there in any car, even my e92m3 with full aero I hit around 131-132. The ass came out a couple times was very manageable. Suspension was super confidence inspiring and stable.

Brakes are definitely the cars weak point, and there isn't much braking on this track but they definitely didn't inspire confidence.

Broke my personal record which was 1:30:9 in both my ZR1 and E92 M3 with KW club sports, full aero and rs3 tires. Without the the aero hit 1:32:8 in the M3.

It is now 1:28:9! If you're not familiar with this track Randy Pobst tested the 991GT3 and C7 Z06/Z07 and ran right around 1:27:3, then GM sent him a revised Z06/Z07 with bumpy track tuning and he went faster. So I am pretty happy with my time for doing 1 session!!!

Here's the vid. I overbrake in turn 1 and turn 9. Gps speeds are lagging behind till turn 5

Cool story

Nice times! Not many cars make a better track car than a Viper TA. Looks like fun...

[roastbeef]

congrats.

i've tried a variety of lines over turn 6 at big willow in my e92 m. if i turn like you do, the car gets a little upset. if i turn in earlier at about the center of the course and hug the rumble strip to the right just over the hill, the car doesn't get upset and traction control doesn't interfere. does it sound like i just need to take the corner later and further from the left?

I've noticed that can happen braking late there, especially since it's downhill car can get twitchy and it happens to me sometimes. Depending on the car i see some people take it how U describe too.

Sometimes the way u say can make u exit too far to the right for the crest (turn 7) which u want to take as straight as possible so u can be on throttle, preferably full throttle depending on car again.

So just depends on car and driving style I think. If u haven't seen jack Olsen's wsir video watch that. He breaks it down well

[roastbeef]

yea, i've watched jack olsen's vid quite a few times. his turn 6 line is the same as yours. its not right for my car, or i'm not nailing it right.
i do like your 3-4 line and want to experiment with that a little bit. i think i was focusing on getting up to the first red dot at the top of the track too much.

[TheKosherStogie]

^ I got caught up with that. I mean he does drive a Porsche and the theory is make a triangle out of turns to utilize the Porsches ability to exit turns.

Watch Billy johnson's nsx video at wsir. He stays low there. It's completely different...see what u think of that. I was actually going to try that approach next time. I'm hesitant because I feel like it will point u too far off for the downhill but he kills it so...

i think the line works because of his car's weight and i'm assuming he has a ton of downforce. if i start to turn in by the second red dot i pretty much use all of the track to the left going down the hill. most of his lines are completely different... i don't think i can turn into 3 that early either.

[TheKosherStogie]

I agree. I drive it more like Jack Olsen. Seems to work well. Driving straight up three to the red turn and get on throttle...

Turn 3 has a lot of compression and no straight after it. Entryspeed and using the uphill to 'catch' you and help turn the car is the key for the corner. If you turn in too late and over-slow the entry, you're leaving time on the table.

For 6, the ideal line depends on your power/grip/downforce/etc... You need to be full throttle over the crest and adjust your line accordingly. If you can take the crest flat easily, then the sooner you can get on throttle out of 5 and open up the exit (which makes T6 more of a corner) the faster you'll go.

For 3 it was like 1 this time. I didn't trust the brakes so was fucking up everywhere braking too early and over slowing cause I almost overshot a couple turns in the beginning and got scared. ;(

The crest for 7 I didn't know if I could stay flat. In my Porsche yes. M3, yes but was hesitant with the power. So...

[nicksm3]

Wow man! That's great and I love the new vipers especially the new ACR, such a track mister from factory. Americana is really doing it big these days!

so you're suggesting to turn into 3 earlier? i've seen a few people now go off at 3 from going in too hot and/or going in too soon.

Believe so, well faster too as I over brake in the video above and turn in pretty late (sort of went together above) stayed on brakes too long. and since there is no straight which is usually making sure u get the best exit possibly, there isn't one here really.

For corners with long straights after them, the focus should be getting the best exit as possible. For corners like T3 with no straight after them, carrying more entryspeed will result in a faster time than over slowing the entry and getting on the throttle early. Since T3 has banking and a compression, even more entryspeed can be had than if it were a flat corner.

The goal is to work up to carrying more entryspeed without over doing it and going off at the exit. So work up to it slowly.

makes sense, i'll build on that, thanks!
