Put the wagon on the Dynapacks with some race gas...

[[email protected]]

and at 18psi it made 322awhp

Drove the car until it was close to empty and put in 3 gallons of Sunoco 114 octane. There was a bit of 94 octane left in the tank so we guesstimated I was running 108 octane in the tank, at worst it would be 104.

Thick red line is pull #1 @ 18psi

Thin red line is the same pull from last time on 94 octane @ 18psi

Difference? 44awhp/40lbft tq

Pretty much proves pump gas in the West Coast of Canada sucks ass.



The boys had plans tonight otherwise I'd burn up the rest of the race gas to see what I could do at 26psi. I'm guessing 400 isn't too far off.

Now I have something to look forward to tomorrow!

**edit**

Here is the 25psi power and AFR plots

[downhillracer]

Damn! that is a huge gain! would not have thought it would have been that much. Bet your stoked with those numbers!

The crazy thing is this is still on the base file.

I can't wait to see what numbers I get on the tweaked 93 octane and race gas files.

[A4TUNE]

wow that thing is already a monster and its not even tuned to its full potential.

[AudiA4Turbo22]

video of speedo on street ASAP

[A4natomical]

jeez, curious to see what mid 20psi would do.

[[email protected]]

We plan to push to 26-28psi depending on how the timing in block 20 looks.

I also plan to do comparison pulls with the TIP attached and then with it off to see how much power is gained by running the intake side wide open.

sounds good. once my build is done im gonna have to do some BIG reading on how all this fine tuning works to get my car dialed in correct

like you said, im not gonna be able to just start it up and turn to the boost way up. :(

after break-in of course.

[A4natomical]

btw...366awhp is around 450chp right? what do you think 26psi on 93 would get you? any guestimations?

isnt the math: 366 x .22 = ~80.5; 366+80=446?

[[email protected]]

To dial in your tune you have to do lots of R&D... repairs & damage

On the first dyno runs I got 349awhp at 25psi

I used 20% drivetrain loss (which is pretty low) to get 349awhp/0.8=436chp

Most people use 25% drivetrain loss so 349awhp/0.75=465chp

I'm going after 400awhp on 94 octane without water/meth injection

[A4natomical]

thats a nice goal. youre 1.9L right?

when its all said and done (probably summer 09) i want to have 500chp.

[dougyfresh]

The BEST thing to do is to get a bone stock B6 A4 1.8TQM and dyno that on the same day, same conditions. The factory is rated at 170chp. You'll get that whp and can then use that on your own vehicle.

You need that updated file Winston!

[mike-2ptzero]

jeez, curious to see what mid 20psi would do.

Its around 10awhp per 1psi. So that would be around 70awhp gain at aroun 25psi.

btw...366awhp is around 450chp right? what do you think 26psi on 93 would get you? any guestimations?

isnt the math: 366 x .22 = ~80.5; 366+80=446?

22% driveline loss for a 366awhp is 469.25 chp.

(366 x 100)/78 = 469.24

469.24 - 22% = 366

[A4 TSCHUSS]

Winston what injectors and fuel pump do you have? And are you on the stock returnless fuel system?

I want someone to log that injector on time block like I did and see what they are getting with 630cc injectors. Nobody has said anything about running their injectors hard at boost in the mid 20s like mine were.

[7speed]

lookin better and better

And who encouraged you to log that block....

[A4 TSCHUSS]

I forget, but it dont really matter I just am curious why these other larger than 1.8 liter guys with 3071 or 3076 and cams and in winstons case a better turbo mani are running 24+psi and dont seem to have any worry when my car was hitting 90+ duty cycle at 24psi. Winston you might want to do a log of the duty cycle before running 26psi like you are saying you want to do.

I mean is my bad ass Revo 440cc gtrs file with atp log manifold and stock aeb intake mani making killer power over these other guys? Just doesnt make sense why my injectors are working so hard and theirs arent or thiers are and they just dont have a clue and could be flirting with disaster.

[mike-2ptzero]

Well I think some people are just way over thinking the injector readings, hell I used to see injector times well into the mid 30's with my stock injectors and K03 setup. I wish I still had those logs.

[A4 TSCHUSS]

So what you are saying is screw it and turn up the boost and log air/fuel and see if that stays ok and just run the injectors at 100% duty cycle? They would be running 100%+ for so long if I did that, I just dont see that being ok, but what do I know.

Just keep logging to see if you actual do start to lean out. I still think upgrading the fuel line is your next step, but if you wish to wait till 034 tunes Mikes car thats cool. I will see if Javad will be willing to share any data logs of the IDC with me. The engine is going back into that B6 next week, I just hope waiting for the new intake manifold isn't going to hold up tuning the car.


BTW it would be plenty shorter then the 14+ seconds of me running my stock injectors at 100% during a 1/4 mile run way back in 2001.

We can use my car for that when it heads up to Gruppe B for some work Winston.

[CO AVANT]

Congrats Winston, it's only a matter of time now.

[dougyfresh]

There you go! Good idea.

[texasboy21]

Does anyone have any idea what kind of 0-60 times thatd pull?? I know there is some sort of forumla using quarter mile times and trap speeds but i dont remember what it is.

barrett

[A4natomical]

Its around 10awhp per 1psi. So that would be around 70awhp gain at aroun 25psi.




22% driveline loss for a 366awhp is 469.25 chp.

(366 x 100)/78 = 469.24

469.24 - 22% = 366

thanks, now i have a solid answer on how to convert

I am running flow matched Siemen 630cc injectors, upgrade Bosch fuel pump and the stock returnless fuel system.

I am logging blocks 1,3 and 20 for Chris but I can do a pull and log the on time at 26psi. What block is that?

We can use my car for that when it heads up to Gruppe B for some work Winston

First thing we will do is do a baseline pull on your car

thanks, now i have a solid answer on how to convert

That's the same math what I was doing

[A4natomical]

which bosch fuel pump? 040?

[A4 TSCHUSS]

Block 002 is injector on time. Then you have to a little math with a formula with the miliseconds given in the log.

[mike-2ptzero]

Does anyone have any idea what kind of 0-60 times thatd pull?? I know there is some sort of forumla using quarter mile times and trap speeds but i dont remember what it is.

barrett

Well that will depend on the driver, but my guess would be 4.5+.

[DeanUW]

Sick Winston!

[vinny.dtw]

I thought you were selling your hooptie?

Good job Winston, I'm jealous.

[Don Supreme]

And who encouraged you to log that block....

I forget, but it dont really matter

WOW - Just wow ............ I guess now I know

----

What injectors are you running right now? Also, PLEASE LOG Inj on time (Block 002 on my b5 ecu)....

left is actual, right is requested and here is the injector on time log with air/fuel and this was a 3rd gear pull. No idea what that injector on time stuff is so fill me in.

They aren't logging it because I didn't suggest that they pay attention; most people focus on block 020. I do not have a lot of faith in block 020. I strongly feel that block 020 fails to tell the whole story about a little thing called pre-detonation.

[dougyfresh]

So, no REP for you Don?

[Don Supreme]

So, no REP for you Don?

I guess, not.......... basically a slap in the face.. I guess I should just keep these tricks to myself.

[sean1.8t]

you do deserve rep, Sean

[Don Supreme]

you do deserve rep, Sean

Thanks Sean

Just did a pull and logged block 002

At 23.5psi the max number was 16.64ms and drops a bit to 16.12ms

So what does that convert to in terms of on time?

BTW... 371awhp at that boost level

26psi is next!

You mean what does it convert to in duty cycle.

I need the RPM to do the conversion

so 16.64 @ what rpm, etc ?

[[email protected]]

It was that figure between 5400-6500rpm
