Here’s what I’m talking about. You can fill me in on where you think rpms are. Top dead centre on the b5 s4 tach is 4000 rpms

Here is you when waiting to go. Notice your left knee? Full extended holding clutch. Rpms low.

Here is you when you’re getting ready and blipping throttle. Notice left knee? Clutch has been let out some to find engagement point. Right hand is down messing with the hand brake. Rpms are where? 2700 or so? Other guy is gone (look at his staging lights)

Now the key one. The moment u let the clutch all the way out. Your knee is all the way up. U haven’t moved the car more than 10 inches (you’re still fully staged) but the clutch is fully engaged.

Rpms? MAYBE 3200.

Still think there’s a problem in the tune? Or did you just launch the car with naturally aspirated small v6 power and bog. You’re launching with all the vigour of a b5 a4 2.8.

Lovely little analysis and all, but I never claimed it was going to be a great launch if not for the throttle cut, simply pointed out that the throttle cut robbed it of a lot of potential.

I’ve said about 50 times that the driver needs more work and that I need to practice launching.

So i think we are both saying the same thing lol.

#44

Nope. We arent.

You are saying this…

Doesn’t sound like you are saying the driver is wrong.

You are trying to make data fit a complicated theory and you are missing something simple. Someone is trying to help you and instead of saying “ahh…ok i see what i need to do” you are blaming the car.

Your engineer is showing.

#45

Looking a little closer the revs were up to 4750 when the throttle was cut but it actually started moving about 0.2 seconds before that so yes you are right it wasn’t the rpms I thought it was, but the throttle cut still killed it as you can see in the video from the outside.

So yeah I need more practice launching at the track. What’s your point?

#46

Well he did not go 137 for one he went 136 which is 1 mph more then tweets BIG DEAL also he is not pushing boost because thats boomers motor SMH :-[

#47

First of all you can’t fucking count.
Secondly this is not Boomers motor… what the hell are you talking about? lol

Boomer is getting a short block. Certainly isn’t this one.
He “wanted” to have this motor and trade for his,. but this has way too much in it for that.

Sorry to break it to you little boy but I’m not pushing it as hard to make sure it’s good for h20.
Once I’m back from h20 I’ll be hitting the track again. You know, something you are afraid to do.

#48

He went 135 you went 136 1 mph difference big fucking deal if he did not run such a low et he would have trapped higher!

#49

You really are a waste of the oxygen you breathe aren’t you? lol

#50

He is right though.

When you have a dogshit launch you tend to trap better.

Anyway when did this become tweets against BT?

Also BT, Wtf are you doing on the launch? Sounds like you launched at 2300 rpm on a car that doesn’t make boost till 4800. You’re basically launching a small displacement v6 that makes 190 hp and 180 lb ft of torque by doing that. The turbo is out of the picture u til you’re almost through the 60 foot trap.

I posted this in Your other thread. Good video for you.

29 psi here. 10.74 ET, so what are you missing?

If the tune is cutting the throttle on the launch, I guess he could always call the tuner and complain. BT…got a mirror in your bathroom? Go yell at yourself lol.

#53

I’m certainly not against Tweets lol, Reid is a good friend of mine and I have nothing but respect for what he did. I’m looking forward for him going back very soon and beating his previous numbers.

As for my launch, throttle cut.
The rpms were at 4750 when I actually let the clutch out, and the ECU dropped the throttle from 100% down to 18%. This caused the revs to drop down to 3000rpm.

This is the log from the launch:

#54

lol that is pretty funny actually! Made me laugh.

#55

I know but it just seemed like the thread was going that way (tweets vs bt) . Not referring to you.

That log shows the pedal (you swing into wot) and rpm and boost and throttle…but not where you actually let the clutch go.

#56

Ah yes I thought that one had vehicle speed on it, guess it didn’t.
447.8 is when vehicle speed went up from 0. Then right after that the throttle is cut.

#57

Sorry 447.65 ish
