Porting Plenum and TVS Inlet - recipe for disaster?

[Brian Z.]

I'm really excited about getting her tuned. Bob Kurgan is tuning her so I know she'll be in good hands. He's probably not as well known on either coast but here in the midwest is very respected. We're going to be renting out a dyno shop here in Indy for him to come down from Chicago and tune a bunch of mustangs: foxes, sn-95's, turbo termi, vorteched notch, etc. so it should be a blast.

That's good enough for me, at least for now. Your gears I believe are 3.55 and I'm running 3.73. I think you also have a little smaller tire diameter. It is interesting that he did need to tune my idle with the L&M TB. It just wouldn't idle right with the GT500 stock setting. I believe yours is set at the stock settings.

I'm at the stock tune settings for the L&M. Your right I'm also running the 2.65 upper VMP pulley. I do have 3.73 rear gears though. I'm actually thinking about going back to the stock gears with this amount of HP. I might have a freak car. I'm good with that! Pretty close though on the HP and TQ. Nice set-up!

Shaun was a little surprised that I didn't make quite as much power as Robert (Joker), but every car is a little different. I hope your tune goes well, good luck with it!

Yep, I was on 91 octane gas. We also didn't have time to throw some race gas in and see what it would have put out on a race tune. I'm thinking maybe over 700.

I have a friend with a GT500 Tvs car being tuned by Bob next week. I have only heard good things about his tunes but have never met him personally. I look forward to hearing how it goes.
