Topgunz - air to air upgrade

redondoaveb · 05-28-2019, 02:17 PM

Some people have had issues with the Stillen bracket flexing (hence the custom brace) but I think it was the the guys running a cog set up. I may be wrong.

Is this the 9lb boost pulley? My best measurement is it’s 2.85” but i could really use a caliper for this stuff. It was included with the kit but I didn’t use it cuz I’m an idiot as overboosting is hard to do at this elevation.
Seems like I should really be using it because I’m already running tbatt’s no-slip kit (on the 8lb pulley—like an idiot) and am guessing that’s better designed for the 9lb setup.
And using this 2.85” pulley for scale on the idler below (guessing maybe 2 3/8 sound about right?) that is the idler I need to change out to the gates 36225 which I think is a 3”?

If your running the Tbatt's kit, 2.87" pulley (a.k.a. the 9psi pulley) will be fine. No need to change its idler on the serpentine side.

Oh man! You hadn't been running the high boost pulley I included with the kit? That is totally why you are seeing such low numbers. Get that baby on there and re-tune. You will pick up some good power.

Yes, the stock tensioner will pick up the slack.

As everything is bolted to the motor I wouldn't think so. There used to be a custom support made for these.

I had that exact support brace but sold it since I have never had issues with flex ,although I am only running 9.5 - 10 lbs of boost.

Wow - what's your setup? How are you getting that much boost? If this is detailed somewhere, can you point me to it? I'm only getting 8lbs if I run it all the way to redline & maybe a bit above.

wideglideleon · 05-29-2019, 04:07 PM

I am running the 9 LB pulley and the upgraded Si trim V3 impeller with a extra pulley setup to prevent Belt slip.

blaineanator · 06-03-2019, 06:19 PM

Stupid question: Is it easier to switch out the S/C pulley to the 9 psi one and risk belt slip at higher RPM's? Or change out the pulley on the other side of the bracket b/c it has a tension adjuster underneath?

The 9 psi pulley everyone is talking about goes on the front (serpentine) side.

TopgunZ · 06-03-2019, 07:58 PM

9psi on serp. Then add my no slip pulley.

blaineanator · 06-04-2019, 08:24 AM

Gotcha. Thank you guys

So is Tbatt's kit only necessary with higher boost numbers?

Tbatt and Topgunz both offer a no slip idler pulley for the serpentine side. It's a good idea for higher boost applications.

I haven’t seen any results when I search on VHR although it looks like Topgunz did it on a DE/HR? Nobody done it on VHR? What do you think about it? Build the block closed deck maybe 9:1 compression, mid or rear mount turbo, turbo piping would go in right before the IC. Doable? I know Redondoaveb already has a wastegate setup he shpuld do it, or at least that’s the next step of progression we could do.
I know newer Volvos are doing twincharged but their reliability is awful, been done on WRX’s but that’s kinda stupid bcuz you gotta build the motor, the tranny... think we could do better on this VQ?

Please move this entire conversation to a new thread. This will clog up information on the A2A thread that will be of zero value to anyone interested in A2A.

Ecutek or uprev? What's best for this kit and the stillen supercharger?
