Topgunz - air to air upgrade

milkcow500 · 11-06-2016, 06:07 PM

Yeah I just realized it's very hard to tell from the videos. Oil is fine and it's not hitting anything. The vibration is very noticeable in person. I noticed that it's only happening at lower RPMs.

Yeah I had a similar issue but my intake tubing was up against my strut brace also. I spaced it out with washers and the vibration went away. Just check everywhere where the piping could possibly hit any of the frame or metal on metal. And of course makes sure the bolts on the supercharger and bracket are really tight.

Dyno results will be coming as soon as all these issues get settled.

I hope you dont run out of fuel up top if that trim pushes a lot harder. There is always a limiting factor when going for more power. Definitely keep an eye on your fuel pressure gauge when they are tuning it. Better yet would be to get a camera on it.

Also, make sure they have a boost reference hooked up to they dyno. It is AMAZING how many shops will not get this out of sheer laziness.

Yeah, I'm road tuning it for now. Seb just sent me an updated tune, but I was still in the 11s at almost-WOT. I'm carefully watching the AFRs, so we'll see how it goes. I'll be on the dyno as soon as I'm ready for E85 and I'll make sure everything is good before we proceed.

I'm going to jack the car up again and check all my bolts tonight probably. Just trying to figure out this damn vibration issue. It's pretty much only happening in reverse now.

Is your car a automatic? I have a vibration in reverse also.

Same here, I'm going to check with Pat@level10 about it.

I spoke with Pat@level10 and he doesn't think is the transmission. He thinks is the exhaust making the clattering and vibration through 1-2 and reverse. He asked me to bring it in so he can check it out but since I'm about 2 hours away I told him I'll take a look first.

milkcow500 · 11-08-2016, 11:54 AM

Yep it's the 7AT. I had vibration before, but not to this extent. It's literally shaking my cabin.

Hmm I completely forgot about the transmission. I'll check everything over again and then maybe give them a call to. They are only 40 mins from my workplace.

Interesting. I'll take a look at mine as well.

BTW, Sebastian sent me an updated tune and it looks like my AFRs are freaking out up top.

At 7k rpms, my car starts sputtering and my AFRs on my gauge start jumping everywhere. You can see on the graph that it's all over the place.

What's causing that ?

He said briefly mentioned that it could be my fuel pressure dropping or an issue with my primary O2/WB sensors.

I ran another log to confirm the issue, so I'm just waiting for him to get back to me now.
