Stupid idea #2 - use one of those rock-screen setups on the SC and then add a filter before the IC (or farther downstream before the TB's)? Can't think of a reason why the filter couldn't be pressurized..

I have been drinking.

I’ve thought about an airbox idea, I’ve seen a few builds using one.

I wouldn’t put a filter on the pressure/boosted side of induction,
As it could force it into your engine or at least dis-figure it & cause disruption in boost.
I’ve seen a few screens on the pressure side of oem diesels (heavy duty w/large holes) but nothing as restrictive as a filter.
When you say bumper; are you speaking of crash bar? As these are modified for various use of different filters & even replaced with smaller tubular ones (such as Fast-Intentions).
Nothing wrong with brainstorming on new ideas; as all these are custom & not oem.

nah I meant the bumper... like pipe the filter down to one of the open cavities on the sides (where FI/GTM/Gamma TT kits put the filters).

Could also use a cobra head, but I think the small 90 would affect airflow.

I have some gen2 sets sitting in my shop. Looking to get rid of them.

My car is at my shop all this week to have the 928 impeller and bearings/seals/ upgrade, have a better intake fabricated so as not to have to use the little flat filter, service, Uprev ARC update and retune on the dyno.

Myself and others have done some testing with using a different filter and nothing is better than the one provided with the kit. But, it will be hard to say if you picked anything up or lost anything if you go with both impeller and intake mods at the same time as that impeller, assuming you will re-pulley and spin at 60K+, is going to pick up some good power.

I have already "re-pullied" and am at about 59,000rpm compared to the stock 50,000rpm. Its been fine for a year like this but I wanted to do the bearing and seals upgrade for durability/reliabilty reasons and thought I'd do the upgraded impeller at the same time.

is the impeller gold from 928 or is that a specially ordered custom gold impeller?

928 coats them and it comes in that color.

I think it's a special tough titanium nitride coating the same as applied to many cutting tools used on cnc mills and lathes to increase their life. It would give the impeller, which is billet aluminium, some extra protection.

"Titanium nitride is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties". Wikipedia

I just ordered the clutch/flywheel from ZSpeed, and Joe asked me about torque numbers at the wheel. I told him no more than 410, and probably 390-400 on 93 octane. I also told him I will never launch the car, or track it. He actually recommended his Stage 2 EZ-Street Quiet Clutch, and while he said I'd be at the upper limits of what the clutch is rated for, that I'd be very pleased with the day-to-day operation of it.

Anyway, long story short, I'm starting to get nervous that I told him the right numbers, and went through this thread and dug out Turtle's, overture's, and redondo's dyno charts. Theirs were lower than what I told Joe...so I think I'm safe. Anyone else with torque numbers on A2A?

I hope to be hitting a dyno day soon (hopefully Sunday), I'll let you know where I'm at!

My dyno torque numbers are 386 on 91 and 440 on e85. I'm running a JWT clutch/flywheel and it holds that power fine. The only slipping I get are the tires in the first three gears.

TopgunZ · 04-18-2018, 09:46 AM

What if you decide to go E85 some day? We are seeing over 450wtq on that stuff. What if you get the 928 full build and throw 13psi at it? Also, what if you decide down the road to swap to a turbo setup where your making over 500wtq? Id go to 450 at a min.
