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.  |
And you are also coming across argumentative and hostile. Some people have preferences others don't. The topic is the 2650 install. There was and is not a lot of information to compare to. Frankly - the way you came into this thread seemed more confrontational than anything. Maybe I'm wrong, but it looks like you and laynlo15 have history already, which is what let me to these possibilities. If that's what it is, stay closer to topic.
