Your AGP was 62mm, right?

Here's some logs showing how the 6766 turbo spools.
I thought it was spooling a lot quicker than the previous turbo but it's either spooling the same or a little quicker... which still isn't bad for a larger turbo!

The car "feels" a lot faster than before even if it's "only" pulling consistent 2.6 seconds FATS times... lol.
I need to dial things back in though once I get my wideband working properly...
I was going to take some video today driving to work but it's pissing down with rain lol.
Maybe on the way home.

**britishturbo** · 05-28-2013 06:44 AM

A few more crappy nitrous install pics lol

Going to try the nitrous in the coupler there for now as a test to see how it works...
If I have to I'll move the MAF further back and put the nitrous fogger further away from the throttle body.

Awesome! I look forward to the videos from this weekend :)... And before that... Do it soon before it hits mid to upper 80s by tomorrow and the rest of the week.. All the S4s should be nice and slow by Saturday lol.

**britishturbo** · 05-28-2013 09:37 AM

Looks like tomorrow evening I'll be picking up my nitrous bottle... took it to get it filled on Friday but the place was out... grrrr.

I'm excited to test it

**Monty23** · 05-28-2013 09:43 AM

Can not wait to get a ride in this bad boy!

**Monty23** · 05-28-2013 11:34 AM

You better get that bottle filled or you will have a lot of catching up to do after the third beep...

lol says the guy putting in a laggier turbo tomorrow

**britishturbo** · 05-28-2013 11:40 AM

So my ebay 100psi pressure sensors came in today.
Now I will be able to log fuel and oil pressure

Which ever gets the better fats time is the one that will be on the motor for sat.... And its a 6262 .64AR; not a 6766 .8XAR lol

And at your rate, you will have a 7175 next month lol

I meant laggier than your 5858 lol.

And there's a lot more to who wins a race than just the FATS time... you should know that lol.
When I hit full boost at 5000rpm and shift at 8000rpm I have a lot more to play with than the FATS time says haha.

Oh and it's an 0.82AR but the housing is different...

I only rev to 7000ish, so fats should be a very good indicator of my power band, but yes built motor would require a revised fats to be useful.

**AudiSportB5S4** · 05-28-2013 12:07 PM

Marc 10 sec used to use "FATS+" for his testing.. 4k-7k. Thought it was a more useful measurement than 4200-6500. Built motors revving out that high could probably do a 4000-7500, or higher!

Only 7000? Even with my stock motor I revved to 7500 lol.

If you want to know who will win a race over multiple gears you need to see what rpm you shift up at and what rpm you drop to after the shift... that window compared to the time taken to do the same with who you are racing will tell you who would be quicker...

Of course the other side of it is the spool up time at the start of the race... lol.

**Monty23** · 05-28-2013 12:31 PM

How does your trans like shifting at 8000+ rpm?

Did u get the turbo today?

**britishturbo** · 05-28-2013 04:17 PM

A quick video from my drive home today. Nothing special just a 3rd gear pull

Nice man! Any difference in maf readings with the new turbo? How much more does it flow? Sets the car back pretty good for third gear :). Can't wait to see this run this weekend

**britishturbo** · 05-28-2013 04:53 PM

I'm thinking of trying it later this week lol.
Want to try Nitrous on pump first though haha

**1gcrazy** · 05-28-2013 04:54 PM

Jesus... Nitrous on Corn would be insane.

Actually yeah I had to tweak the maf settings some which I didn't expect... even at the same flow it moves more air and needs more fuel... if that makes any sense at all lol.

**LINDW4LL** · 05-28-2013 04:54 PM

How much power do you think you can make on methanol + 93 with the 6766?

**britishturbo** · 05-28-2013 04:55 PM

This car is so weird... when I'm not expecting it, it catches me off guard and can scare the crap out of me lol, the next run It'll seem slow haha.
turbo fun and games

All I know is I need more power! 600WHP ish isn't enough haha.

**britishturbo** · 05-28-2013 04:56 PM

I dunno... I have the meth right now on 93... My goal was 600whp but I'm already up around there lol.
I might try 35psi tomorrow

**britishturbo** · 05-28-2013 05:00 PM

I also dropped down from the #12 Meth nozzle to the #7

It is weird... I wonder if its maxing out. I noticed in your vid you have it settling around 12.2. Is the motor quiet at that afr and boost level? What timing are you running up top? Looks fast man keep it up!

Not maxxed, it's at about 4.1 Volt.

It's a hair leaner than it's supposed to be, dialing that in now lol
