240 km/hr on a short straight!!!!

You are racing with some FAST cars!

 

GT2-RS, Pista, SF90, 765LT, 900hp M4-CS, 1,000hp McLaren 570S and some cup cars and challenge cars, just to name a few.
We even occasionally have a Senna out there holding us up. 🤣🤣

 

Is the 900hp M4-CS the one with the cracked AP rotor? I recognize those F8X front sway bars.

That is some serious competition! Other than the GT2-RS no one tracks those here on a regular basis.

 

Pista 1

Pista 2

Pista 3

Pista’s don’t lift 🤣

 

3 Wide


We almost got booted for being three wide down the straight 🤣

 

Good eye. Its not the CS, but it was an F80 M3 (700hp).

The CS has Brembo Type III. No cracks.

 

That’s what they say 🤣🤣🤣

 

I had my first GT2RS track sighting today at Homestead. A black one came out in the advanced group during the DRT event. And yes, it did pass me. LOL

Every time I see @4 Point 0 's car I have to wipe drool off my keyboard. Keep this up and you will owe me a new laptop! LOL

I’ll post some more once the GT-R brakes go on.

 

Yeah, easy way is to create them in youtube and post link here.

 

I'm about to order diverter valves and noticed that you are using TurboSmart BOVs. Are these vented externally for some turbo noise? If so what model do you have?

 

Diverter valves are BOVs. At some point along the way someone decided they needed a new name. You can use HKS or GReddy if you’re a JDM fanboy and don’t mind paying the tariff. They all have optional configurations that let them hook up to hoses just like the OEM valve. You don’t have to vent them to the atmosphere. 4.0 lives in the land down under, so the TurboSmart ones are likely the most affordable because they wouldn’t have tariffs or international shipping costs like a US or JDM brand would in AU.

 

I'm aware they are the same just wondering how the incorporated the TurboSmart valves and his overall experience with them. Super loud no interest but light woosh wont kill me.I just like to look at all options before making decisions.

 

You must be absolutely killing the brakes lap after lap and running basically all-out.

I believe I said this before, we've used Stoptech on our BMW 335 race car for years. The car "only" makes about 400hp and weighs 3200lbs. and we've run 12 hour endurance races without any brake issues.
I do recall doing a 6 hour endurance race at Mid-Ohio with BMWCCA and hitting 155mph (250kph) down the back straight lap after lap and still had no issues. We had a pretty good fight with a couple of cars, so I wasn't going easy on the car for sure.

Again, I know this thread is super long and I'm sure you've addressed it, but additional cooling ducts I'm sure would help. We have 4" cooling hoses coming from the front going directly to the brakes.

I have the APR BOVs on my 991.2. You get a nice "whoosh" sound when you leave off the throttle. Sounds so old-school good!

 

A whoosh is good, I'm not into JDM exaggerated blow off sound.
