My first Audi - 2001.5 S4 with Custom Single Turbo setup...

I hope chatterbox was from fat finger syndrome... this thread should have been in the Project & Build forum since post 1... fixed.

Well I'm back up in high boost mode - ~37psi.
Got the 1700cc injectors installed and almost dialed in :-)

Managed to hit a 1.88s FATS this morning on the way to work with no nitrous!


The run also worked out to be:
100-200kph: 4.9seconds
60-130mph(2mph short :/): ~5.45s

[Austonwerner4]

Is 1.88 the highest anyone has on here?

Where do you think the nitrous will put you?

[Monty23]

Well peak torque is at ~5200rpm right now and the FATS starts at 4500.... so moving peak torque (via nitrous) another 500+rpm earlier should help a bunch... this is the turbo I should have bought first

I can't wait to see what E85 does for my 6262....

on the side of the road with another blown up motor

I have to agree with this .......but if lee isn't happy with 1.88 fats I guess that's the only thing left to do ....lol
Or bigger turbo with a small helper turbo or supercharger ......would love to see this

Yea. The mains on the rs4 block are a little more beef, but they are still webbed.......

Stronger. Yes. By how much? no one knows- it could be marginal.

ITguy just cracked the mains in his car, lasted 4 months at 600whp/600wtq on e85 with SRM K24's. It was an early APB.

Yeah I'm afraid to runt he Nitrous to be honest... unless it's a very small shot like 30hp or 50hp.
I might try that, otherwise I don't want to push the block to the limit :-)
Or rather, I don't want to find where the limit is!

[britishturbo]

Video from that run on the highway in mexico this morning...

[Monty23]

Yeah, that block is worth a bit too much for R&D ;)

My SRM car is so beast it breaks at idle

[Monty23]

Speaking of idle, how are the 1700cc injectors?

How much PSI?

[britishturbo]

How much PSI?

Right now I'm at about 37psi

[britishturbo]

Just dandy :-)

[britishturbo]

Virtual Dyno plot of that run:

[Monty23]

Just dandy :-)

I wonder how it would idle on gasoline....

Car must feel glorious at 5200 rpm

It feels like I'm about to go wheels up, close the flaps, and put away the landing gear :-)

And if you're going for 700whp or less 1000cc should be fine...
I'm hitting 57.5% IDC now on 1700s lol.

Even on e85?

[rtl5009]

Even on e85?

Yes, rail pressure can be bumped making those 3 bar 1000's into 1200's np.

[AudiForeman]

Thank you. Great work Lee

[britishturbo]

Correct,

1000cc injectors running at 4 bar (not 5 because that's silly) are around 1160 to 1180 each, then add in the meth and you gain about 100cc per hole there too.

My 1700cc guys are closer to 2000 with the fuel pressure and meth.

[britishturbo]

So here's the current plan for the 3.0 build - most parts are already in my hands or will arrive this week:

JE Pistons - Custom 10:1 comp FSR w. coated skirts (Integrated Engineering)
JE Tool Steel Wrist Pins (Integrated Engineering)
Integrated Engineering Connecting Rods (Integrated Engineering)
ARP L19 Rod Bolts
ARP Main Studs (Integrated Engineering)
ARP Head Studs (Integrated Engineering)
CNC Ported 2.8 Heads
+1mm Supertech Intake Valves
+1mm Supertech Exhaust Valves
Supertech springs & Retainers
Supertech Solid Lifters (034)
LOBA Mechanical Cams (Loba)
3.0 Crank (obviously lol)
Billet Block Reinforcement (Details to come - 2001.5 APB Block)
Billet Aluminum Oil Pan (Details to come)
Billet Aluminum Intake Manifold (If it's done in time, otherwise RS4 for now)
Billet Aluminum Valve Covers (If time permits - just because they would be cool lol)

I'm sure I'm missing parts but that's what I can think of for now...

[spd579]

How'd you decide on the Loba cams? and please replicate everything billet for me please, I voluenteer to to help with R&D! ha

This makes me happy, with a slightly smaller turbo I hope to have the same (if not better)spooling charachteristics as this graph.....I'll only be going to around 30 psi though

[getslideways]

When might we start seeing the intake take shape? I have been really curious as to what you have conjured up for this.

[britishturbo]

I was going to get some custom grinds done, but the LOBA cams are made from new billets... so they will be stronger and last longer.
Plus they have a lot of experience in the matter and I trust their testing lol.

Plus not many people use LOBA stuff stateside so I thought it would be nice to do so ;-)

Well the 6466 is quite magical. It spools the same as the 6262...

[Monty23]

Doesn't e85 affect spool?

[britishturbo]

Doesn't e85 affect spool?

They say E85 makes it spool quicker, I saw zero difference.
I think it's a result of the higher timing you run with E85 ;-)

[Monty23]

What exhaust housing are you running with the 6466?

[britishturbo]

What exhaust housing are you running with the 6466?

A 0.63
With no power drop even at 8000rpm compared to the AGP 0.82 housing.

[sherbet]

oh my god! that is just ludicrously fast man. well done.

[sjmelling]

For those who asked about my idle on 1700cc injectors:

Whoops. Fixed.
Sorry about that.
