Are you spraying the inside of the silicon couplers w/ Windex? It's a really good lubricant for them. Makes them slide on much better.

I work at a dealership so I tried using an aerosol silicon lubricant. The rear throttle body connects up fine its the front one that is being a pain in the ***. Its almost as if the pipe needs to be dropped down further but to do that ill need to start cutting in to the metal.

Mine was def a PITA to get installed. But after ample cussing & lots of Windex & lots of wiggling of the Y pipe, I was able to get it to fit. You certainly shouldn't need to cut anything.

If Seb is tuning the car he has MAPs he will sell you.

For the guys getting tuned on speed density; works best when its a hybrid tune using the (stock) MAFS when out of boost, then a 4bar map sensor and speed density when in boost. Full speed density ( no MAFs at all) can be kind of jumpy between weather changes

This is all based on a turbo car but I'm sure its the same for you supercharged folks.

TopgunZ · 07-27-2016, 10:51 AM

That is what Seb does with all the cars he tunes with MAP. The "hybrid" version.

future370zzz · 07-27-2016, 01:50 PM

All good info to know.

TopgunZ · 07-27-2016, 02:13 PM

Or you can always upgrade the MAF's. They typically sell a set for $700 new and $500 or under used.

Dyno run scheduled for Aug 6th at Z1. I hope I have the leaked fixed by then. I'll be pulling the front fascia off this afternoon and going back over all of the couplers. Then I will rig up a pressure test and make sure there are no leaks.

I do remember that a couple of the joints were not all that tight of a fit and I had to really crank down on the clamps. I'm wondering about building up the tube with some tape so that the coupler fits better. I'm thinking that the silicone coupler is not squeezing down smooth on the inside and that may be causing the leaks.

I'm open to suggestions!

If you've got couplers that want to pop off, hosing the pipe down with hairspray will help it stay in place.

TopgunZ · 08-01-2016, 11:27 AM

Just start with the pressure test. That will point you in the area of concern and go from there.

TBatt · 08-02-2016, 09:21 AM

I found the problem.......the moron that did the installation (me) left the clamps loose on the coupler that connects the outlet of the intercooler to the Y pipe. How I was getting 7psi is amazing.

Now I can't get any traction to do WOT. Friday the Quaife will be installed so that should help. This car has become a BEAST!

Will the FI tow bar fit around the intercooler on the A2A setup?

On my Gamma V3 kit they just use spacers to attach the factory tow bar.
In my particular case the spacers weren't big enough, nor could I grab enough threads on the inner 4 studs.... However, I did make up my own spacer/hardware setup that did work and spaced my factory tow bar out about 9mm. The bumper and foam reinforcement seem to still fit just fine. =)

That is great to know. I should have done another check while I had everything apart last night.
