I believe it was around 8 psi.

So, If you overdrive the 2650, you can pick up more TQ down low? All the blower stuff is a learning curve. I ran Nitrous for years in my different cars, this is a different animal.

Several factors for sure.

Those are some great numbers.

I was just saying on a stock car with a stock fuel system(which the thread is based on) the 2300 looks like a better suited charger. The 2650 has to spun too low and the power curve shows it. 2300 delivers a better power curve at low boost.
You are wrong if you would want to give up that much torque across the rpm range at the power levels being discussed here. You also have to think about time spent at X part of the rpm range and shift extension. Dropping 90whp on a shift isn't ideal. It's the same principal as putting a F1a-94 on a stock car and only spinning it 8psi. It's going to make all peak power. There is a reason why there are different size Chargers for different applications. The 2650 is a unit that likes to be spun harder. Look at the curve Mike posted. Even making 15psi, it still produces slightly less power under 4k rpm compared to a 2300 @ 12 psi. That tells me this unit needs to spin 15psi minimum. Nothing wrong with that. On a application like yours, the 2650 makes sense. On a stock internal car running 10psi or less, I think a 2300 is a better choice.

2650 is not really even doing much @ 8psi under 5k rpm because the rotor speed is so low. That is why you see the power ramp up so fast and there is +90whp gain from 5k-6500rpm on the stock SS. The 2650 will make a lot more torque low mid rpm with a smaller pulley, but it will easily run above what the SBE LT1 can handle to get there. On a build where its being spun to 18+ psi, you will see the torque come way up. To keep it in perspective. On a street car a 550/550 or 580/600 power curve makes for a fun little street car. With a DR you can manage that power. However when you step up the build and start making big power, ideally you don't want the torque matching the horsepower and linear power increase becomes more ideal. This is where the 2650 will shine along with maintaining low air temps. I think Laynlo is mixed up between threads. My comments were based all on the fact were discussing a stock SS. The other thread was discussing 2300 vs 2650. The 2650 is better suited for high HP builds. Moderate builds the 2300 is plenty just like I said before in your thread.

It'd be nice if we could compare stock to 2300 to 2650 (that's tuned to liking). Then we could all have some numbers to better think about and compare.
It's nice to have so many options.

Mixed up, always. Too many 2650 threads.

Gearing effects shift extension not Power. Far as Transmission. Most PD stuff does not require a converter. Most folks that chooses to add one it's going to be a fairly small stall(<3000). So shift extension isn't going to change much on a PD equipped A8. With a 28" tire you are looking at 12-1300 rpm shift drops, except 3-4 which is like 600. M6 cars drop 1700+ unless they drop down to a 26" tire. Far as traction. I am running a Whipple and with a 305/35/20 555r traction is not a issue. My initial dyno was 600whp/570wtq in 5th gear. It honestly looked a lot like the dyno curve in the OP but with more torque. The car felt no faster then bolt-on under 3k rpm because it had no timing down low. I added a bunch of timing back including a couple degrees up top and I am sure the Torque came way up. Still didn't cause any traction issues and the car is much faster. I can pull bottom 3's 0-60 on the street no problem. So no I wouldn't want to give up a bunch down low. It's much more fun to drive with the added midrange. Now it pulls from anywhere and doesn't stop. Big shit eating grin on my face after I dialed that in. Room to grow is relative and It's all a balance...you don't want to sacrifice power under the curve for a big peak number. Hence why big cam cars never run like the power suggests on the street. It's all about the combo. Point is the new 2650 looks like the real deal for the right application. However most will not utilize it's potential with their build. The 2300 is plenty capable and has been mid 9's @ 145. Even the 1740 has been high 9's @ 140. So yes if you want to run 8's with a PD, then the 2650 is the right choice. You are right it's other peoples money. I am simply offering my unbiased opinion based on my knowledge and experience. So I offered my two cents for those that would care to read an opinion from someone not trying to sell a product.
