Topgunz - air to air upgrade

Pauly Z · 04-29-2016, 09:53 AM

Update...so Seb says the cruising logs look great. We are troubleshooting an issue where the transmission gets hung up and doesn't want to shift in 3rd or 4th gear between 3-4k rpm.

Will never fit plus your mafs will still be pre charger.

Sawzall a hole in the hood and weld a hood scoop on! I thought this was uhmareca! Then put a gol dern maf sensor behind it. Bewhitey water to air kit! comes with 100mph duct tape

(that would probably be a fun project)

Update- So today we were still detecting knock. Seb sent me a tune with only 17 deg advanced WOT and it still knocked. He said that this pretty much confirmed that it was detecting false knock. He said there is absolutely no way it would be knocking on e85 and only 17 deg advanced. He plans on desensitizing my knock sensor and we will try again. Seb said this sometimes happens to supercharged Zs that he has tuned because the blower is attached to the engine and it detects its vibration. On a positive note, I did hit 11 psi today!

Strange. Ive had dozens of dyno tuning pulls and never picked up knock.

Is this all still on the same tank of gas? Id almost want to drain It and get some Ethanol at a different station.

Yeah Seb said he has never seen my issue. With the changed torque values in the tune the transmission would get hung up between 3-4k rpms and wouldn't shift. He changed the torque values back to stock and it shifts fine.

I wonder if he was going off of my built trans torque values on yours. Is your stock? At first mine was doing the exact same thing and would take around 15-20 seconds to shift. I would have to let off the pedal a little and it would shift. He has it dialed in perfect now.

Pauly Z · 04-30-2016, 10:28 PM

That's exactly what mine is doing. It only does it in 3rd or 4th gear

Could it be the different piping that Evan is running in his kit? Topz...weren't u using that same.kit in your car before?

No, I never ran that pipe since I am only able to MAF tune.

EVOHUNTER · 05-02-2016, 09:15 AM

im still trying to combat this flutter.

Im kinda stumped, Does the spring need to be a lot stiffer to stop the flutter, or does it have to be a lighter spring to allow it to stay opened.

The tighter the spring, the more flutter you will get. You basically just want enough spring pressure so that it stays shut on boost. The lightest spring will have the least amount of resistance to vacuum therefore getting pulled up and away from the pipe.

You get flutter when you are part throttle right? That's because you are going from 18in/hg of vac to say 5. The spring pushes down towards the pipe but the sc is still blowing air out of it at 5in/hg. So it pushes then pulls then pushes etc....

I had the lightest spring in my Turbosmart dual port and still trimmed it down by like 1 and a half coils. It worked perfect. Problem was that it cant purge enough air when you let off the throttle at 7K. It can flow maybe 300cfm when it should be blowing out at least double that.

The Tial QRJ is the way to go. It has very minimal flutter but is very loud due to how much air it can let out of the system. Just put a hose from the outlet to inside of the engine bay somewhere and it should be good.

Hey topz, I just bought that adaptor from ebay, im about to order the Tail BPV, do I need the 1.5 or 3.0 psi spring.

thanks brother.
