Always impressed with your work Helicoil, nice job. By the way, is this car your daily driver? If not, how many miles do you put on it in a month?

. I run a 27 x11.50 QTP Hoosier. 3.70 gear
I don't drive it daily, only on nice days and when I feel like laying rubber for a couple hundred feet. 
I bought the car 3 years ago with 2800 miles. Head and cammed the LS1 and raced it for a year, then did the Procharged LS2. The car has 5200 miles on it now, and the LS2 has 875 miles on it. So considering this thread is a year old, the answer to your last question is about 72 miles a month on average, obviously by the condition of its belly I don't drive in the winter, or the rain.
Thanks for the compliments! The last track outing yielded some great results but another blown up Procharger plenum. This one popped at WOT. From what I recall it was right at the stripe. Kaboom!! I almost **** myself!
I don't think it affected my times at all. A couple pages back I showed a repair I did on the last one sometime last year. It was doing O.K. until I spun up the Procharger.
I had another spare I got when I bought someone's 3.5" intercooler kit and Procharger piping/hoses for spares. I got it all for $35 I think from the for sale forum on here. They gave me the plenum for FREE because it was blown up too. Well, I am glad I got it, because after powdercoating mine it is going to be easier to repair.
Here are some pics of mine after it blew on my 9.80 pass.

I started working on the spare Procharger plenum today. I didn't know if I wanted to go back with this set up, but I decided to. At least for the end of the year. I'd like to go back and run a couple more times at the track. Fall is the time.
I spent about 3hrs today welding on this thing after glass beading it. I fixed the original split in it, re-welded some other seems on it and then made some reinforcement pieces to try and keep it from exploding.
Tomorrow I will finish it by installing 2, maybe 4 stansions in it like I did my last one. Then I will get it powdercoated satin black to hopefully make it look cleaner

Procharging just wasn't for this car. Changed directions with this one and bought a Procharged race car.

Verdad Gallardo I had the FLT Level 5 (at that time) with a good intermediate shaft, so Level 6 or 7? Trans is still in the car to day taking high 10 sec whippings. Who knows how long it would have lasted behind the Procharged 403, but I had no problems. I made at least a dozen 9 sec passes with it and probably 25 low10 sec passes. From what I remember the converter re-stall wasn't worth much and I would have liked to ran it in its tighter configuration once I maxxed out the D1SC.
Whatever you do, re-inforce that aluminum plenum box if you run the twin intercoolers and add some better BOV's or better yet go FMIC.
I just this week had my SS hood repaired after a year or so and I was finally able to part with that unnecessary money. Turned out nice though. Water under the bridge.
