I wanted to give some info on how a stage 5 car runs at elevation. A few weeks back was able to hit the track and get about 10 passes in. Track prep was slick but it is what it is my car is full weight 991.2 running PS4 tires.
My 60ft was a best of 1.7 but seemed to stay 1.8-1.9 so that happened. Also car just couldn’t hook. Tried the race tune and did 145.7 at 10.6 or so but just didn’t want to do much. Went back to pump gas tune and ran better but still spinning all over. Either way 10 passes all in the 10.3-10.8 range with no issues anywhere from 140-145 wasn’t bad for 5300ft elevation and DA in 6000-6200 range. For reference there was a plaid there and his best run was a 9.90 and avg 10.0 at 146-149.
Here is a vid of some runs with a cool guy and his GTR. Car was turned down since it is stock block but has made 950whp if I recall and was closer to 800whp on e85, drag tires, built trans and BL1200 turbos. He was a better driver with better reaction and 60ft but my little VW did work.
Needless to say I sent data logs to Sam and he saw some areas to improve the race file for my crap elevation. So I’m sure with his magic we can go faster.
Good news is car is so fast on the street but just doesn’t like the traction on the track and being im on the street 99% of the time I will take it.
I will also attach some VBOX runs from the street so everyone can see.
Im sure Sam can speak the technical stuff if you have any questions.
Hey! Great runs with the GTR and that’s a real measuring stick. To come from behind and pull ahead so easily on an 800+ wheel car is awesome. The surface just wasn’t having it with the Michelins. Lol I agree on the Nitto’s. The latest file should be a little spicier. Looking for a few more mph.
V12TT congratulations on some amazing runs despite the high altitude and lack of traction! If you had more normal conditions and decent traction you would of course shave many tenths off you ET and pick up trap speed as well. I love the video with you walking on the 800 whp GTR
My car is now at World with @SamboTT@ByDesign to get the short block beefed up and a Dodson clutch installed. I ran in the 9.3s with Sam's lower end Stage 5 tune but am of course tempted to try a higher level Sam tune with the Stage 5 but Sam did warn me I would be playing with fire and so I opted to beef things up rather than end up in a situation where I have a rod go through my block or breaking the PDK etc so my decision was to be upfront with solidifying my set up and not incur extra core charges with blowing my stuff up! Ha ha.
I do have an extra set of Nittos for the rear if you are having a hard time getting them - I literally waited over 6 months to be able to get them on hand - but probably won't need them urgently so if you are having a hard time finding a pair then I'll gladly ship you a pair for the price I paid for them plus shipping if you want to try a pair out. Just DM myself or Sam and they can be on the way. Also many thanks to @onfireTTS who has posted about them I've been a very grateful user of them. With the stage 5 set up managed to get a 1.38 60 foot time with those in the rear and Toyos in the front. I feel a bit like a "dog in the manger" with 2 brand new pairs sitting in my garage when others are having a hard time getting them.

I am watching these Stage 5 threads carefully and waiting for the right moment to upgrade from stock turbos to these amazing things. The torque is shockingly high and early (great driveability!) which makes for a double edge sword - solid upgrade over stock turbos, but slippery slope to fortifying bottom end rods and PDK clutches to get more results out of the upgraded turbos.
The factory billet .2 TTS units are about the same size. But it’s not always about size. Just like anything even complete engine design has a lot to do with performance more than size. Often times as you stick a larger compressor there, the efficiency actually goes down. Your compressing more air, creating more heat and you’re removing more material from inside the compressor cover which has function. That’s why we worked with TiAL for a long time to get here. Our TiAL 68mm has always been up top in VTG performance as one of the top offerings and has a great track record. There are some cars that have highly developed tunes and run really fast with the 68. In those cases it’s not always worth upgrading to this next level but it’s hard to continue pushing a certain system and platform more and more, at some point you have to stop. The idea here was to make a little more power with a little less back pressure and effort, mission accomplished.

I get to drive 2 cars and make direct comparisons between them. My daughter's 2017 TT the stage 4 set up with the Tial 68 mm's from @SamboTT@ByDesign versus my 2018 TTS with Sam's new stage 5 set up. My daughter's car is set on one of Sam's milder Stage 4 tunes and is around a 9.6/9.7 sec 1/4 mile car with a best of a 1.42 sec 60 foot and 145 mph with the Nitto rear and Toyo front tire combination. She says that is fast enough and that roaring down the 1/4 at 1.45 mph requires enough attention from her that she's not interested in dialing it up. The car could probably be pushed to go 9.5s @ 147 mph but for now she's fine with where it is at and that is probably better for long term durability with the stock ,motor and pdk.
My 2018 TTS with the Stage 5 is not only more powerful but to me feels more controllable because the power comes in ever so smoothly. Running 9.3s @149 mph I feel like there isn't much that could beat me on the street. However, when the car ran 9.6s there probably wasn't anything back then that could beat me - except maybe a Mclaren 720 or 765LT from a roll.
With the stage 5 you definitely pick up power over a stage 4 for any equivalent level of tuning and also better drivability IMO..
We love to drag race competitively and the Red List series is one of our favorites. However, that series requires you to make 12 full 1/4 mile passes in less than 4 hours. What usually ends up happening is that some car blows up and oils down the track which requires an hour to an hour and a half clean up. So that means having to make several back to back passes in order to hit your quota of 12 runs before the cut off time. So you might be doing 12 passes in 2 hours.
The August Red List events can push ambient temps of close to 110 degrees F with DAs well over 6000 feet. Doing repeated back to back passes with no cool down whatsoever is an endurance test for any car. GTRs and Demons are literally blowing up on a regular basis under these conditions.
Sam has my car set up on the stage 5 with a relatively mild tune where it is running 9.3s with a 1.38 60 foot time. That being said. under 110 degree ambient temp conditions with back to back passes the question arises as to how long a stock bottom end and pdk will last. If you blow your motor or trans the core charges can be pretty high. So that's why I decided to go with the upgrades on a proactive basis. Those upgrades will also leave me in a good position should NHRA change their rules and allow quicker runs without a 12 point cage in which case I would be able to switch the Sam's XR set up.
Additionally they allow me, with more peace of mind, to try a more aggressive stage 5 tune and maybe run 9.2s at 150 mph.
Most people don't go to the track as often as I do so it's more likely that a stage 5 set up won't risk hurting the motor or pdk as much as for someone like myself.
Everyone uses their cars differently.
However, I will say the stage 5 has enough advantages over the stage 4 that for someone like myself its been very happy transition. My daughter on the other hand is perfectly content with the stage 4 on her TT and set on a mild tune.

12 passes in 2 hours is an incredible stress.
When I ran True Street we had to caravan drive 30 miles and then make 3 passes back to back to back without pitting or opening the hood in 20 minutes. You could only check tire pressure. No prep.
I would turn the controller off and run 8.8 to 8.9 at 156-158 mph.

I assume you are running meth to get those numbers?
