Nice graph, bet that would be 700 at the wheels on a Dynojet lol

 

A little update on the VTG progress. All times 4th gear, flat surface, no decline, no brake boosting or any other little help that I could try Just pedal to the metal and the car does one run after the other like this...

This is not my car so I will not go for the record run, but I think it has a couple more 1/10s in it that could be activated on a dedicated run. Whoever has the record for 997 VTGs: take a look in the rear mirror. I am right there

 

My best on pump was a 6.7, but I only tried twice. My best on E85 is a 5.9, with a total of 3 tries all 6.0 or less. I make 40 whp and 45 wtq more now than then, so hoping to set the record deeper into the 5s this winter.

 

What are your list of mods and do you have a built motor right (as I think I read that on a thread)?


Your car for sure is moving out.

 

Nothing fancy: GT2 VTGs with bigger compressor wheel, GT2RS intercoolers, turbo intake piping, exhaust with switchable valve/flap = straight pipes when you want to, still running cats, built engine, Sachs clutch for 1000 Nm. OEM injectors - I am at the max with fuel now and need the rest for safety reasons. Nothing more to gain on top and I also think this is it with VTGs without more cooling (E85 or meth). Running pump fuel (Aral 102 preferred, Euro 98 will do)

 

You consider a BUILT MOTOR $$$ nothing fancy!!


Are you chasing the fastest stock framed VTG record?


If so that is different from those that have current 60-130 times on VTG's as they are on stock motor. For ie. RobTunes 5.2-5.3, A418t81 and others are all on stock motors.


When you have a built motor you can tune full tilt for tq/hp down low with out worries of the rods. For a smaller turbos like our VTG's, that is a huge benefit as that lower power / tq (where these smaller turbos are itching to let go more power & not up top) would get you going a lot quicker especially down low in rpm in 4th for a 60-130 run.


Chasing a stock motor car records with a built is kinda apples to oranges comparison.


Either way 5.6 is hauling the mail and is a fast machine, but with the for-mentioned taken into account.

 

No, I am chasing nothing and I also don't believe these stock car stories until I myself have run and measured/logged such a car

There is a lot of talk here and there and not always is the full story unfolded. You need torque to move these cars and if you play safe, time is running while you are being nice to the rods. Time you will never pickup later, regardless of what you do.

That being said: regardless of what these record holders did, they deserve credit because they found their way to do it. I am not here to take anything away from them.

 

What is the modified Vtg record on stock motor does anyone know ?

 

From the forum 60-130 list

5.88 - Milou / 997TT AWD TIP (stock internals)

 

5.50 - KerCar / 997TT TIP (stock internals)

Running Champion 68mm VTG kit with our Tiptronic kit

Running pump gas + toluene mix.

 

There are stock motor 991's with the stock frame turbos with the 68 wheel doing 60-130's in the low 5's on flat surfaces / summertime conditions. We will see 4's soon.

 

That's pretty quick, but I also wouldn't expect less with a PDK transmission. Downside is these 991 turbos are pretty expensive. Way out of reach for me for a tool to play with.

 

whats the record for a vtg 6sp 997?

 

I think it was RobTuned, havent seen any posts from him in a while.

 

VTG 6 speed 63mm turbos is Rob of Robtuned. It was a 5.2 or 5.3. I hold the stock turbo record with a 5.9 so far but there are others who have run 6.0-6.1 with the same mods, so mine isn't an outlier, nor I am doing anything shady as has been advanced as a theory.
