Aside from tuning issues, the amount of boost doesn't really matter. What matters is how much heat is generated to reach that boost level. Unless they go out and design more efficient heads we'll have to keep raising the boost level to achieve more power.

Yes, exactly. That's the point of getting this in the first place. 20+psi is where it's at.

.......this is exactly my point. The 574whp is being made at 17psi, which is similar to a 200mm pulley. Those that plan to generate more power from the Weistec s/c by running larger crank pulley should keep this in mind. The point is that the weistec s/c is already a high boost set up. If the Weistec s/c was making all this power at low boost, it would be a different matter.

I'm also betting that the Weistec also runs less parasitic drag at high boost /high RPM freeing up horsepower that way.
Also don't forget that it's also taking 50lbs off of the front of the car

Also true, but at higher boost levels it'll make cooler boost than the oem one at lower boost levels. Plus, a monkey can make a better intercooler than the oem one so I'm assuming it's better.

Well.... it's making that boost at a higher efficiency so the discharge air is cooler than a stock supercharger. That cooler discharge air is higher density and that folks is what makes power.

........actually, there really isn't that much evidence that the Weistec is a more efficient supercharger than the oem s/c. The Weistec is making its power at much higher boost. At the same boost levels, both s/c's are making similar ammount of power. Now I'm sure the weistec might be more consistent, but that remains to be seen

what does that mean? the larger unit can make the pressure ratio easier and do it while maintaining it's pumping efficiency. Translated that means more density and lower outlet temps mean more efficiency

Ted, you can only make more power at a higher boost level. Boost is a measurement of restriction in the engine, without changing the heads/cams or modifying them you'll always need more boost to achieve more horsepower in a given engine assuming the outlet temperature after the intercooler is the same. You won't see these really shine until they get into the 20+psi range, the point being you can't do that with a stock SC.
Kudos to Weistec for pioneer this sc set up. Out of this whole thread the most exciting to me is the elimination of the sc clutch.

here might be a stupid (if i overlooked something) but viable tuning question, but, how the hell is this engine reading airflow? i saw no maf and no map on my teardown. is it only reading tps, vs. rpm on a basic map, then fine adjust via iat and o2's?
i know clamping the maf or map is a solution on cars that have them, then a piggyback with higher reading map to carry the fuel maps to the higher boost levels. in this thread i hear guys are hitting a wall at 17 psi with tuning, but, with no maf or map, the tables should be based mearly on tps and rpm and no real reference to boost.
help me out on this one for those in the know.

That's why I said "assuming the outlet temperature after the intercooler is the same.". The SLR has a much much better intercooler then our cars. Are you certain the SLR's are making 20psi, I had never heard that before?

they also have EXCELLENT intercoolers compared to ours...... That's why they can make serious boost

if that is the case, would the slr map sensor be set to read higher? certainly it would be easy to adapt. ecu should not know difference, just scaling would go higher and a little less resolution to the maps.

after some research it appears the slr one is the same. i did how ever find an audi 3 bar sensor that should be good to about 25psi i suppose. there is even a chance it could bolt in place of our stock sensor. looks like it has iat temp integrated into it also. pretty easy to rewire once pinouts were known.

As stated earlier, this setup clearly has the potential to make power. Lets just hope the ecu has the flexibility to handle it.

I know they have made similar power at similar boost but I am not sure if the stock supercharger runs were made on pump gas or race gas. I know some people have made 580whp range with a 190mm pulley.

Our stock MAP sensor is the same sensor used in the V12 Bi turbo cars making well over 20lbs of boost with no problem so I don't think the MAP sensor will be a hurdle. Everyone needs to remember that in most cases people with higher HP numbers with bigger pulley's are making those numbers on a dyno jet and only for 1-2 pulls with the car cool. Maybe the weistec kit can make the same power level pull after pull. I'm sure if you throw some timing at it and race gas that 575hp would turn into 675hp being that they tune on 91 octane. Ported heads and cams would be worth another 50-100hp easily with a much more efficient blower. With ported heads and cams to compliment those boost pressure will fall and HP will go up so increasing boost to get back to the same level will give you even bigger gains. The weistec isn't for everyone but it will no doubt put the stock blower to shame for those looking to make big power.

haters crazy
This blower has been proven to make power on other platforms (800+whp on 63, and if you want to get into domestics theres tons of info). I understand some peoples skepticism but I can't wait to get my hands on one! Hope one is waiting for me when I come home lol. My only concern for max power would be stock motor and what it can handle. I'm ready to go nines when the track opens back up
