Just about everyone selling them...
These have a 6 speed auto with a deep 1st gear and pretty evenly spaced ratios, a converter feels mushy when you have something like a powerglide with a 3.08 rear end. Like i said the LS1 cars had a tighter converter stock, they also had 350 cubic inches, and the 3.23 rear with a 3.xx ist gear and a 3600 converter didnt feel bad at all. A 4.17 1st with a 3.15 rear will feel even more coupled. I dont know if you's 1/2 a second with the converter swap on these with one of these, of course having the proper converter is just as important. Just bolting any aftermarket converter in isnt the answer, like anything else you need everything to work together to get maximum performance and the guy selling and making you the converter has to know exactly what you are doing. Plus there is a big difference between high quality converters and junk, you certainly get what you pay for there, unfortunately there isnt a lot of choices for these so far.
Its just kind of a fluke how well the PD blowers work on these, the gear ratios and stock converter just seem to work well with it. Its not magic though, even though there are a few 'magic' cars out there that defy logic. Throw a little automotive passion, a little nutswinging in along with some free or discounted parts and forums can be more confusing then help at times.
If you want a PD and Bob is a Whipple dealer, get a whipple, its the same kit as the Roush except for the blower itself. Some say the twin screw is better but for the displacement and boost levels of these either blower moves enough air to easily blow up the stock engine.
My only beef with the TVS is it was way too easy to achieve my goals, so I buy wheels/tires and actually wash and wax the car once in a while. In some sick way I kind of miss the skinned knuckles and swearing while laying on a creeper on a cold garage floor and wrestling torque converters, headers and gears in a late model car lol.

Lol, thats the beauty of technology! No more busted knuckles on your back to go fast lol.
What kind of power were you making to trap 127 and then 131?
Got it. Thanks.
If you want more HP over the Roush TVS Kit Tune that comes with the kit,give Justin at VMP Tuning a call and buy a SCT after market tune.

Well, just like making the 'perfect' pass with a manual trans somehow working your ass off or hurting yourself to achieve the same results is pretty manly to car guys.
That is until you get old
I never had the car on the dyno, the 127 was with Justin's tune and 7psi in -300' DA and the 132 was 9psi with Justin's tune with a couple of my miinor tweaks for timing, shift points and fuel at +1000' DA.
My times are on 524hp/497tq, I think the DA was 700 that night.
My car pushes 9-10lbs of boost.
Total mods, Blower, K&N filter, Roush AB's and wheels and tires.
I didnt touch a thing or change air pressures, drove to the track made two runs and left before I got kicked out.
Car was full weight with nothing removed with ~half a tank a gas. Some extra weight on the car was the wheels and tires and a tool kit.
I get the same mpg as before the blower and it is my daily driver.
My car isnt as fast as Kevin's, but his car was the inspiration for mine. Got to give him some props!

Who did your tune?
My car went 117 on 6 psi and 126@ 11 psi and letting off. I fail to see how the Roush or whipple have proven to be better than the centri. I'd say they are all pretty equal. All except cost. You can have just as much fun and go just as fast for less. And btw I'm at a DA OD 7200'.
What was your ET?
Meh 11.7 was the best. Had some serious issues with traction lol
Finally somebody that feels my pain. Thin air is a bitch! I got an 11.2 spinning off the line with a slipping belt on the 69mm pulley on my roush kit in 6900 DA. Same setup at sea level would be low 10's and be running me out of fuel.

Ain't that the truth haha
Is your hp/tq what you made at that altitude or corrected?
Corrected.
That makes more sense to me now. I was thinking that 700+ should go way faster then you said, but corrected HP and ET not corrected, it makes more sense.
