I have a question for you guys. I have an 06 A6 with a Procharger running 6psi. Currently you can not tune out the TQ Mgt from the transmission. (Please no debate on the TQ Mgt it exists) my delima is the slow 60' times (2.0 - 2.1 no wheel spin). If I was to spray a 50 dry shot would that help coming out of the hole since the computer can only pull so much timing? Would you need to retune the motor for A/F?It hangs now at 11.0-11.3.
Please be descriptive if possible.

Thank you in advance for your comments.

I see a couple potential issues. You really shouldn't spray below 3000 rpm, and with no converter, trans brake, etc., you're leaving at such low rpms that you won't be spraying until you've moved out 20' or so anyway. I'm not sure how much hp the blower robs at low rpms too, so you are really in the dead zone launching a non-stalled auto car with a procharger that doesn't start making power until higher rpms (just like with the juice off the line). It would probably help some, but I'm astonished that you have no wheel spin on runflats. You may get 1.8-9 out of it with all the factors and tq mgmt fighting you. As for the A/F, the dry shot uses the MAF to compensate, so with just a 50 shot, you should have no problems in that arena, assuming you have upgraded injectors for the procharger (especially if you spray a narrow window to get into the procharger's powerband, like 3000 to 4500 or something, but you may be cautious of the upper rpm spray and a/f when the procharger starts shoving air in hard).

We have a forum member (Mr. Big) that's just about to do the same thing you are asking about, so he should know in the next few days!!!

 

I saw a stock C6 A4 with tire and 150 shot run a 1.63 60' and 11.4@121 DA was ~5000 feet that day.

He sprayed at WOT

 

What tire? DR or ET Street. That can knock .1-.2 off your 60' easy.

 

It would spray at 3000 RPM and probably to maybe 5000 RPM. Basically once 4.5 psi of the S/C kicks in the spray automatically will go off. Unfortunatly there is not a Converter for the A6 yet and no 19"DR's. We did upgrade the injectors from the Procharger kit. I swear little or no spin off the line at the track. SO do you think it will work?

 

There's only one way to find out...

On a serious note a few of us have been the "test market" for a LOT of the F.I./N2O stuff... You'd be the first paddle shifter with that set up that I know of, so no one can say...
As Ron said, we'll be installing a dry kit on mine starting this Sunday, I'll have more answers for you then. My car is a Z51/MN6 though...

We are having to tune mine today. I sprayed it once on the dyno and it had fierce knock at 5200 rpm...pulled 5 degrees! We need to get some other tables in there and bump up the injector duty cycle a bit.

C6 nut, I think it will definitely help, just not all it could given your limitations (no converter for the A6 yet, etc.). Your spray window sounds perfect, but if TM is killing you, it may kill you with the spray too. The spray will add tons of torque though, so it will very likely help you drive around tq mgmt. You'll probably start spinning and end up with the same 60' times...just my bad luck!

 

Let me know how it goes. I hope it works for you. We have an event here next Saturday called RSD (Real Street Drags) I was hoping to beat up a few cars.

 

I hope I am on the fringe with the spinn as it does not happen so far. I run a 50/50 mix or 93 and 100 octane to stop any knock if it should occour.

 

We wound up doing a 100 dry shot in the Procharger intake. Goes on at 1400 RPM shuts off at 3000 rpm. A/F stay at 10.9. Got a 1.8 60' and an 11.1 1/4 mi at 129 MPH on F1 super Cars on the DYNO quarter mi simulator. We are going to Byron to try it on the track on Sunday. I will post.

 

Just a heads up for you, I've called yank, PI, protorque, none of whom offer a converter for the A6. My idea is to possibly have the stock converter restalled.

As for your 60', I've gone 1.88 more than once in my A6 with stock stall and runflats. 24 psi seems to work well for me, and I heat them a little, Id on't care what anyone says, it helps me.

How's the A6 holding up to the extra power?? I think I might hit mine with a 100 shot.

 

 

The rain held us from going again today. I will go Saturday 9/30 but I did drive it in some safe places. It loves the shot. I am sure the 60's will be great, The A/F stays fat and power is unbelievable.
