Will it blend? (BritishTurbo build)

Well gee no shit i I went WOT on that graph then at 3500 it’s not going to have much boost.
If I go WOT in 3rd at 3000rpm by 3500 I’ll be at 10psi at least.
If you really think that 10psi with the timing that E85 lets you run is only going to be the power of an NA V6 running pump gas then I don’t know what to tell you.
I could show you guys logs and the dyno plots showing how much power is at 3500 rpm when going WOT below 3250… but you know what? It’s not worth my time. What’s the point when you’ll just try and find something else to poke holes in. I mean seriously?

You guys never give up trying to find holes in things do you?

I believe he meant at the stage when launching. Typically you’re in vacuum, unless you’ve changed the tune to preload at the line.

No he didn’t.

He meant that if you look at his dyno sheet, which he had done the other day, he is making 285 whp to 300 whp at 3500 RPM. Of course we haven’t seen it yet. Just the peak number.

Screw it… here’s a 3rd gear log from yesterday at ~35psi…
Went WOT at 2800 and some.
I even put the power estimates on there too for you along with boost.

It gets really old people telling me how my car performs when you’ve never seen it yet alone driven in it. Does that make sense?

Cheers

We can play with logs all day.

Just help me out.

You have a 2.7 litre V6. You are miles from being in boost at 2500 - 3500 rpm (which is what I said earlier before you started working only with the absolute top of that range).

Do you really think you’re making 300 wtq down there? Answer honestly.

Because I’ve driven B6/7 S4s and B7 Rs4s that make around 300 wtq at 3000 RPM, and when they launch off 3000 RPM, they fucking ROCKET forward compared to what your car does down there.

Your car, when launching at 3200 RPM (don’t make me pull up the screenshots again) vomited on itself with a limp dick and cut a 2.5 second 60’ time. Because it makes no torque down there. Not because of some fancy throttle problem. That was you bogging like mad because all motor V6 cars with AWD and no torque to get you moving launch like ketchup coming out of a glass bottle.

You’ve had this pbox for a week. No times yet? You keep posting logs and fats.

Make sure you have an SD card (not SDHC, SD) in the PBOX and then send me the .pbn file and I will verify it for you. Third party style.

lol…saki ;D

I would just like to add…yes this continues to be wha tIm talking abtou… somethings BT says make no sence… Great point saki… none of this is a stab at BT its just an attampt to say…

Lets look at this another way. Here is my RS6-R’ed A6. Logged last week. Don’t mind the violet line, I was using an MBC that day.

I’m hitting 275 wtq @ 7 psi at 3000 rpm.
By 3500 rpm, I am at 400 wtq @ 15 psi.
and at 4300 rpm the car is producing around 575 awtq.

My car builds boost slightly quicker because the turbos are smaller, but, with a big turbo you will get more airflow through the system on less pressure.

Boost Pressure is really a roundabout measurement for how much air an engine flows. At 0 psi, any supercharged, turbo, or other forced induction car is already flowing more air than the n/a equivalent.

That civic, honda accord etc references is no longer valid because it is not PEAK boost or spool when the turbo car stops behaving like an NA car, it is around 0 psi.

Anyone who drives a forced induction vehicle knows this.

Also, while my graph of psi might rise ar a lower rpm than BTs car, a measurement of airmass flow would be much more valuable to see what power level BTs car is at given a few rpm reference points.

If there is more massflow, there is more torque.

I think you are talking around the issues to point out that I was wrong on something, but you’re losing sight of the discussion. You might be right…there may be more cfm than a similar displacement na car when he is at nearly 0 boost. How much?

Let’s put it another way. If he is making a supposed 300wtq at 3500rpm (which is irrelevant because he was launching at 2800 but let’s pretend), that would mean…

All motor he is making around what… 180wtq (generous)?

So boost, which is low single digits to zero, is adding 120 wtq ?

At 3500 rpm that is a difference of around 80 whp or about 100 crank hp. So using a general rule of thumb that you need 150cfm to make 100 crank hp, that means you are saying his nearly idle turbos (sorry, turbo) is moving an extra 150 cfm.

Sounds extremely optimistic.

Want to play with grams per second instead (on a car that may have been tuned to make that irrelevant. scaled maf? )?

Again using an approximation, you are saying the turbos are moving an extra 100 grams per second in order to make the approximate 80whp required. That is a fantasyland log dyno from that creep who lives in his mom’s basement however… Can’t remember his name… , so I’m not sure g/sec ‘dynos’ make a load of sense as ‘the answer’

Anyway do we see that anywhere? Do we see his turbo moving an extra 150 cfm way down there at low boost?

What did his dyno show?

just to help

this quote is way wrong.

[quote]My car builds boost slightly quicker because the turbos are smaller, but, with a big turbo you will get more airflow through the system on less pressure.
[/quote]
your car builds boost slightly quicker because you have better turbos… bigger or smaller turbos have no effect on measurement of boost. Boost is the measurement of restriction. your measureing how hard it is to push air into the motor. Rs6 or gt36 boost shows you how hard you have to work to push in a set amount of cfm. That is deterimined by the system not the turbo.
