Nice, glad it was an easy fix!

Re: 2G auto S/A daily
 

Shift box is in and works awesome!

Next thing I have to do is a knock sensor.

Re: 2G auto S/A daily
 

nice! you going to run this thing this weekend? or do you still need more tuning?

Re: 2G auto S/A daily
 

Needs tuning, period. It's up to him when it happens, though.

Re: 2G auto S/A daily
 

gotcha!

Re: 2G auto S/A daily
 

Yeah more tuning. Tom should have time Friday of you wanna go out.

Nick, download and unzip this.

Re: 2G auto S/A daily
 

So trying to stall my car and seeing if I can build boost. It kinda works but can only build 6 before pushing threw the brakes.

Here's what happening.

When I hold the brakes down and give it gas the brake pedal pushes up like there's no vacuum.

I have a 1g intake and tom said there is a check valve on 1G brake boosters. Well mines a 2G and I don't see that on mine.

Wondering if anyone has had this issue and what to do to fix it.

I've read toucan pump the brakes while the car is off to relief vacuum pressure in the line.

Thanks

Re: 2G auto S/A daily
 

Maybe put in a check valve?

Re: 2G auto S/A daily
 

I'd put in a check valve if it doesn't have one.

Re: 2G auto S/A daily
 

Yeah I will I'm gonna look at the 2g mani when I get home see if there's one on there.

Re: 2G auto S/A daily
 

There should be a factory check valve on the booster (2g)... Right were the vacuum line attaches to the booster. Even with the check valve I'm sure you will blow through the brakes.

I'd just buy a electric vacuum pump from Summit and wire it to the brake switch. Thats what we are doing with Vassils car. Get rid of the line on the manifold and every time you hit the brake pedal, the vacuum pump comes on and creates awesome vacuum for the booster.

Re: 2G auto S/A daily
 

Fixed. Just had to put a stock line in.

Re: 2G auto S/A daily
 

Ok jake ill look into that. I know people use vw pumps?

Re: 2G auto S/A daily
 

I have the VW pump it works Awesome. Have you done any more tuning?

Re: 2G auto S/A daily
 

Gonna try to get out tomorrow.

What V-dub pump did you use?

Re: 2G auto S/A daily
 

Nice, glad to hear it was easy fix.

Re: 2G auto S/A daily
 

Audi also has vacuum pumps, they use them to lock the doors.

Re: 2G auto S/A daily
 

Dropped off a turbo to Aaron and went out to test the stall.

Kinda showed me a few tricks and they worked pretty well. Got the car to stall up pretty good and didn't move an inch. Then as I let go I quickly ran out of first with no shiftbox in hand so I got out.

Ended up doing so knock sensor logging to and only are seeing .04 degrees of knock so all is well there. Car is running around 11afr and timing is safe so hoping Shane can squeeze every last hp out of this setup.

Also looking at the logs we found that the turbo is moving 55lbs/min of air at 25psi. So at 30+ I'm hoping it will run me into the tens.

A couple more street outings and a tune date set for the 24th and I should be ready to make my first pass in the auto. Now I just need to check some schedules.

Awesome! can't wait to see the final results!!!!
