Topgunz - air to air upgrade

TopgunZ · 04-06-2017, 09:26 AM

I am undergoing a major project utilizing the stock manifold for a new supercharger kit. I bought a 3D scanner and am starting on this project soon. It might be Rotrex based. I am aiming for a turn key kit for under $7K that will make 500whp.

You the man. How much boost can the stock mani hold?

Much much more than any supercharger that will fit in our cars can throw at it. Like 22psi from twin turbo threads.

Hey can you PM what kind of scanner you got? I have been wanting to get into 3d scanning, modeling, and printing but I'm not sure what kind of scanner can produce CAD quality models.

Got a bit of a left field question.

For those running a boost gauge, I presume it also reads vacuum.

What mmHg do you see at idle when the car is warmed up?

Please post your BPV model as well.

I'm seeing about 18 mmHg of vacuum at idle and when warm with a Turbosmart Kompact (Blue Spring + 25mm Inlet/Outlet, soon to be 34mm). Just curious what others are getting.

Mine sits on -21/-22 using the TIAL valve that came with Topgunz kit.

Is that definitely when warm?

And where is the vacuum source? For example, I'm using that tiny port that comes off the runner for Cylinder 1.

Yes definitely when warm at the normal idle while stationary and it's taken from a connection tapped into the Stillen inlet manifold.

So is mine, but specifically off that tiny port off the runner for Cylinder 1.

I'll look up the email if I still have it to be sure, but I queried Sebastian on what normal should be and his response was -19 to -24

Mine sort of runs that range. -21, -22 is more or less the norm but when things are really warmed up can see -24. I have a spare BOV and have been curious to swap it and see if it makes a difference. Will be changing again though when Topz kit gets here so haven't bothered with it.

Same outlet as you guys, tee'd off the reference line.

Need to fix a faulty relay/fuel pump that died on me last night on my way home first though otherwise it will be sitting just shy of zero no matter what!

TopgunZ · 04-08-2017, 08:23 PM

Looks good!

Might want to face the tial the other way. The air coming out is very hot and will heat up your intercooler.

TBatt · 04-10-2017, 01:33 PM

Ok, guys. I've been getting lots of inquiries about the kit so I have stuck my neck out and ordered enough to do four kits. I'll make the spacers this Friday and the rest of the parts should be here early next week if not before. The cost per kit is $160 plus shipping.

This may seem like a lot for what it is but the parts are expensive and the time to source everything isn't free. The nice thing is that you won't have to scrounge all of this up, you will only have to open a box and install.

I found a source for SS 12mm bolts so that is what the kit will include. Only the best for our Zs.

Damnit, I spent over half a year trying to find a pulley spacer for the 54mm pulley. I eventually had to get a machine shop to custom make one...

Not sure if someone asked this before, but any tips on cutting the extra rib off that belt or do I just take a utility knife to it?

Yes, you can do it with a utility knife. Just use a new blade and make each cut about six inches long and about 1/16 inch deep. It will take several cuts to get all the way through. The HD belt is tough!

I'm working on a design that will cut the rib off on my lathe so it will be really clean and straight.

It doesn't. I'm probably the cheapest person on this forum and that seems like a deal.
