Well as some of you know the original plan was to use a Roush TVS kit except use a GT500 Eaton M122 blower. The plans ended up changing and I ended up putting the Roush TVS kit completely on my car. I would have liked to done the GT500 Eaton M122 just to be different but I’m more than happy with the results of the Roush TVs. I’m actually ecstatic about the results to say the least.
Most of you know that the Roush TVS is the blower that comes on the Roush P51 cars. These cars have built blocks and run ~13 psi with the 7.05” crank shaft pulley and 2.95 upper blower pulley. This became a problem for my car since my car has the stock block. After some deliberation, I decided to run the stock 2.95 upper blower pulley with the Steeda UDPs which uses a 5” crank pulley and a larger water pump pulley. I was able to reduce boost to ~7.5 psi by using the Steeda UDPs. I might end up going with a VMP 2.65 upper blower pulley to get another two or three pounds of boost out of it, not sure. I spent the weekend working on the car, only a few hours here and there. I finally finished the car Monday after a slow process. It wasn’t too bad of an install though, Roush’s instructions were pretty decent. The Roush TVS kit is a very well put together kit. I’m very happy with the outcome and think it’s a very clean set-up. I really couldn’t be happier with the way the kit looks and how clean everything came out.
Now Tuesday the car was tuned by Justin at VMP Tuning. I had Justin email me a tune to limp over to his shop to get it on the dyno. I’ve used Justin in the past and have had nothing but great results with his tuning and customer service. So, it was a no brainer that Justin was going to tune the car. The first dyno pull we did with the temporary tune the car put down 420 rwhp at only ~7.5 psi right off the street. I was thrilled to say the least !! After a few more dyno pulls and changes we were able to put down 462 rwhp and 428 ft lbs. Pretty good results, right? Wait, I forgot to mention … I’m running the stock fuel pump !! I’m willing to bet there is a lot left in the TVS with the addition of a set of GT500 fuel pumps. I’m going to be ordering them ASAP and getting the car re-tuned. I will post results once that happens. I couldn’t be happier with my decision to get the Roush TVS blower kit and have Justin from VMP Tuning tune it. The tune is spot on and drivability is very good. The car is super smooth and feels good during daily driving and at WOT. Now I just need to get a set of drag radials !! Kudos again to Roush and Justin from VMP Tuning !!
