My street car has a PTA-52 turbo. I have a 3000 stall PI 9.5 lockup converter. Spools very quickly. Not as quick as my previous TA-49 but then there aren’t too many turbo combo's faster spooling that that. I like it a lot although pricy but I "had" to retain the lockup feature....
art,normally we use a 3200stall 9/11without a brake and a 2800 stall 9/11 with a brake with this combo .although we use and sell 9/11s we also love to use the 9.5 or 10 inch protorque units as they provide better torque multiplication off the jump.www.ckprerformance.com
