Topgunz - air to air upgrade

JWillis72

Looks right to me too but I don't have Tops kit so I could be wrong.

What really doesn't make sense is you have the kink in there and making 5psi due to it. But you were making 10psi and the tial adaptor pipe can be installed at the same position or length.

Did the heat from the supercharger hitting the kink create a soft spot or cause degregation to the coupler in that area and now it won't hold its shape?

I ran into this exact issue trying to use the 45 degree coupler off of the SC. That is why I went to a 90 degree and it does not collapse. BTW: I'm using the the stock 25mm Bosch BOV.

If someone has a good picture of how you can use the 45 degree coupler there I would love to see it. The only way I could see it working is if the outlet of the SC is pointing downward, almost straight down.

Ok guys I finally found a way to do it after getting hump hose couplers. Here's pretty much what I ended up doing.

1. The two bottom couplers are only attached to the pipes the width of the clamps.

2. The coupler that goes to the sc volute had to be forced up a bit on the side closest to you (the coupler will be in more on one side than the other - mounted slanted pretty much)

3. The bottom side of the 45 degree coupler - I shoved the pipe in ALOT more, which helped bring the piping at equal height to the bottom piping.

There's a negligible amount of kinking still, but it looks pretty damn good now. The only issue I'm having right now is that the pipe is touching my fog light now, but I'll deal with that later. Please refer to the pics for reference.

Thanks for posting the pictures.

Are you using the 2.5 diameter pipe that is supplied with the A2A kit? Mine would not reach far enough to go very deep into the 45 degree coupler to keep it from collapsing.

Yes I am. Before, the 45 degree coupler was just in about an inch or so (the width of the clamp + a tiny bit more).

You should be able to push it in a decent amount in order to level the bottom of the piping with the BPV piping. Keep in mind that the piping will be bowed outward a bit, but that is what the hump hose couplers are for.

Who would be interested in ditching the Stillen intake manifold?

I have a design for an air to air upgrade that will simplify the entire stillen kit. You can re-use your stock intake manifold or you can upgrade to the GTR conversion from RJ MFG. PM me if your interested as I am working with them on giving you guys a complete kit to do this and take all the guess work out of this upgrade.

to clarify:

This would only require:
1. Rotating the SC'er
2. Vertical flow intercooler 1 in 2 out
3. 2 x bov
4. new piping
5. relocating the MAFs into the charge pipes
6. re-installing intake manifold or GTR conversion

I think I may try an experiment and see what happens. I'm planning on using two 90 degree mandrel bent 2.75 pipes, one at the SC outlet and one at the BOV coupler to the intercooler and couple them together with a short piece of straight 2.75. I'm not expecting much but I'm concerned about the reduction in pipe diameter to 2.5 inch for that section. At the low boost we are running compared to some of the turbos it probably won't make much difference, but then again you don't know until you try. My thought is to have as smooth of a transition as possible from the SC to the IC.

The intercooler in and out are both 2.5" so that would become the bottleneck at that point.

True, but I'm hoping the area increase at the 90 degree turns of the airflow will be less restrictive.

Do you know what Vortech charges for the SI upgrade?

That is why I suggest using the 45*. Follow the steps Milkcow posted and it should work good. There are a lot of others out there with this kit and this is the first i have heard of it being an issue. I think one guy posted that it wasn't an issue whatsoever.


The upgrade is $700 and i think shipping is on top of that. But, it will net you 2 psi more over your current trim.

Okay, I'll give it another try when I take the front end apart this weekend. I just don't understand how it will work. Guess I'll try jamming it together and see if it will stay open.

After talking to Seb and Vortech, it looks like the only way to reach my power goal is to upgrade to the Si. What I don't understand is why I'm down on power compared to what everyone else is seeing. Shouldn't I be at 420-430 whp at 8.4 psi?

Like I was saying on the phone, you have 44k on your belt that sounds like never had any conditioning. That serp belt across the 9psi pulley has like 25% wrap, 180 is suggested optimal, and is probably pretty dry. Hit it with that crc I suggested before anything else.

Stock cats? Those will cost you some serious power loss if so.

How much timing do you have?

You mean guesswork like this recent post?

GTM stage 1 S/C - Throttle not opening fully? Or boost leak? Please help!

Its all a part of Forced Induction.

But on the lighter side of things..Can't wait to see it! Seriously though, even if it pulls some guys away from this kit I would like to see your design.

I replicated my kit to help out forum members that wanted an A2A system. I think a dual intake design would be even better, pending price since 2 Tials will cost $500 alone.

When local buyer Z4life came to pick up his A2A kit I showed him how it is possible to make this kit utilizing the stock intake manifold, so he can attest to that. It is possible, so again, I would love to see your design.
