Topgunz - air to air upgrade

nic370 · 11-27-2017, 05:16 AM

Any idea what if any negative effects jwicks found with this set up
I want to do the same.. my filter is black with road grime and taking the charger off each time is a pia

You can try it. But you will lose some power due to the insane bend in the coupler that needs to fasten to the SC. I tried a few different setups and the one I supply made the most. Also, I think it is just as hard, if not harder to take the front bumper off instead of 5 bolts from the engine bay. No need to jack the car up also.

I'll have a play over winter
Mines of the road now any way so plenty time to play with it
I might find I stick with the filter on the blower bit personally I find removing the charger a right knuckle scraper.
How much power difference was you seeing topz

Pretty sure you have the wrong forum member listed. I’m not running a SCer or Topgunz A2A upgrade.

Hey TopgunZ how do you release the tensioner for the belts except by jacking it up and going at it from below?

TopgunZ · 11-27-2017, 07:39 PM

You don't need to take the whole bracket off. Just the sc.

You can get at either tensioner from above. Either use a 3/8 drive breaker bar (need at least 2' for enough force to move tensioner) for the serpentine tensioner or use a 9/16 (I believe) crowfoot with some extensions, and electrical tape to hold the crowfoot on, to turn the SC tension bolt. You'll have to forcibly move some coolant hoses out of the way (not disconnecting them) to get to the serp tensioner.

It is much easier to get both from below.

Here you go. Another small but nice feature about these new units is the steel braided oil drain line is coated in a clear sheathing. I must have donated at least 20 separate finger drops of blood when dealing with my old unit.

Finally got a hold of 928 on the phone yesterday and the supercharger should be getting sent back to me with refund minus shipping. I wish communication was better because I would have rather sent them a new shaft and completed the build but I'm just going to take the full kit from Aaron anyways and leave that one as a backup in case the one in the kit goes pop (although if it's the Si with the 2.85" pulley I think my motor would be the first to go). Which pulley is coming with it? I was going to go with the 3" and Si to start but I'm up for whatever.

TopgunZ · 11-28-2017, 11:21 AM

The kit will have a 3.20" serp side high grip pulley with a special new mod for more added grip. This will virtually eliminate slip on the serp side. Now the SC side will have a 2.95/3.47 combo and will not slip. This coupled with the Si trim will make around 550whp.

Is this estimate based upon e85 or 93 octane?

TopgunZ · 11-28-2017, 12:40 PM

93 Octane. It also depends on the tuner. Some tuners know these VQ motors much better than others and can make some great numbers.
