what no excitement!!!
What I really am excited about is the shorter diameter. This should really help my gearing in some areas where i dont really want to shift. Just have to be more careful of the wheel due to the shorter sidewall.
may end up selling these 18 x9.5 wheels and go with a 17"

Shorter diameter...
With those smaller donuts, you'll need to give the curbing a little more respect, Denny; might want to avoid it altogether.

Very nice, we're getting ready to put on a new set of 245 NT-01s on Barbs car, she went to the cords yesterday at the track. We feel the same about the smaller diameter.
Let us know how you like the Hoosiers over the Nitto's.

Guys---?????
my maf readings have fell to 290g/sec at 7.7K in 3nd gear, load of only 160. Ambient Temps are moderate.
I did notice i am only showing 8lb of boost--maybe slipping belt? Didnt hear anything
WTH?
Car actually felt pretty good.
Dont believe numbers all the time?
Oh yea fuel trims went to hell also --vary between -3 to -7 during closed loop.
Time to reset computer and tap dance?

Had a great time at Palm Beach International Raceway NASA event on Sunday. I got to road race my car four times for a total of 10+ laps per heat. This was my first time at a mayor road course and it was well organized. They are very strict to their schedule and nicer group than previous autocross events.
There were a couple of issues with the car initial setup.
1. I had to close the gap on my NGK 10.5 plugs. I had random misfires on the first heat. Took them out closed the gap and problem resolved.
2. I was able to tune my meth (start and full spray dial) by the end of the second heat. It is hard to do before hand on the streets.
Other than that the car performed flawlessly.
1. My Toyo Proxes R1R performed flawlessly but I’m going to try the Proxes RA1 once the current ones expire. My NASA instructor was highly impress with the performance of the tires and the car. He did mention that he runs the RA1 on his car.
2. My Hawk HP brake pads performed flawlessly along with the ATE Super Blue brake fluid. No brake fade whatsoever.
The only big issue was the heat. It was super HOT!!! My engine coolant climbed to 225+. I had to take it easy after the 7+ lap because by that time I ran out of meth and my AIT climbed to 140+ from the normal 95-100 at full boost. I already took care of that problem by adding an extra meth reservoir.
Love having the intercooler fluid pump and extra electric fan on/off switch. I let it run for about 15 minutes after each heat in order to keep the air/fluid flowing.
I was able to dance around thru the turns with a couple of Shelby Mustangs, late 90s early 2000 Camaro SS, highly modified Porsche 944 turbo. No problem passing everyone but the Shelbys on the straightaway but nothing like blowing my doors when passing by. I was always on their tail once we got to the turns. I did not push my car that hard due to the ambient temps and very seldom did I go full throttle. In fact, I kept my rpms to just above 7k.
Next event is on Oct 3rd at Sebring. I was told that it is a longer track and bumpier. I hope the temps are a bit lower by then. Sorry no videos this time cuz I need to tether my windshield camera mount to the car. NASA rules. Will have it done before then.
All I need to for now is to change the oil/filter, bleed the brakes and install my new silicone radiator hoses. Life is good.

Welcome to the addiction dude! Nothing like it. Glad you had a great time. NASA puts on a good event. Next set of tires get some designated rims and go with 17's and a shorter tire. 
I always enjoy others coming up to me after a session and saying how fast my car is and how they were caught by surprise. Hehe.
Dude--imho you need a bigger secondary radiator --trying to tell ya as one southern boy to another. My coolant temps (same rpms basically and I do go full throttle) never reaches 220F.
I trunk mounted my w/m tank--little over 1 gallon. Works great.
What w/m settings did you end up with ? Still using the 60 and 100 size jets? 60 pre blower?
What are the top speeds on the track you were running?
Did you hold your boost? Any belt slippage?
I have learned to always carry a new belt with you to the track. Once it starts slipping --may as well get a new one on there for the w/e.
I would LOVE to be on track with ya Dude--not that would be Christmas.
I have found my car actually runs better with oem plugs, i dont have to close the gap any, but i do just a tad for insurance. I believe if we were not using water meth then we would have to have colder plugs, but with it the oems are fine. I am running the twin fire (i know, I know)
Now another Ga club member just got a new set of Hoosiers ( he couldnt stand it!)--so we are forming a "Hoosier your Daddy" club. lol.
I think guys my MAF grams per sec reading change is due to me placing a big **** K&N filter on and no screen. I was running the AEM dry flow before. I think maybe the airflow was not smooth enough? We shall see.

My radiator and secondary are just fine along with the mazmart pump, thermostat, water wetter and 90% distilled water. The problem is the heat; it is brutal down here compared to Atlanta. Even Cam told me that it was a big difference between Atlanta and Sebring.
I now have just over a gallon on meth but in the engine compartment. So, it should be fine for the next event. Yes, 60/100 jets with the 60 pre blower.
No belt slippage and boosting 10+ under 6k rpm.
Not sure about the top speed at the track but I think I heard 140+. There were some serious race cars at the track too.

I am sorry guys. Sometimes I know I can enter a post and come across as sounding like a "know it all". My bad. I dont mean to be that way. I just excited about friends tracking and start running my mouth.
Juan you are absoulutely right--baby steps. That is the way to do it. And, if your interest increases (and it will) then other "stuff" will follow.
Glad you had a grand time and stayed safe and drove home OK.
World changes after 115-120mph--doesnt it?
I have to include coming to a NASA Sebring event with yall on my buckett list.
Now I have beg to differ about the heat. When Cam was here it was a little hot but it was below 100F. We have ran many a day with 100F+ ambient and the pavement at 150+!
228F is starting to push it. For less than $100 you can solve this.........
But heck cooler weather is right around the corner--so by next year you may want to think about this?
Wish the heck I could get 10lbs of boost. Highest I have seen is 9. It will hold at 9 and 9 is available by 2.7K.
I have the prosport boost/vac mechanical gauge hooked up to the lim. I verified the reading with a mechanics boost/vacuum gauge. Maf is usually great, but 9Lbs is all I got. I am still waiting on the new Pettit by pass I ordered last week. Maybe mine will not let 10lbs happen?
Video next time?
I will post some next week of our RA experience. We have 8 cars on track this coming w/e.
Wow.

OK Supercharger gurus. Here's a question for you.
At the rear of the SS is a vacuum hose nipple (sitting in the drivers seat, right side of blower housing rear) that comes out to the middle of the engine and then the hose goes to the intake. Now. Is this hose suppose to draw large amounts of vacuum? Or is it a simple breather hose for the back of the blower case?

Secondary mechanical contributing factors: slipping belt; dirty filter, obstruction of airflow intake, or boost leak.

getting a cobb to tune with found one for cheap so i grabbed it while i could, what are u tunning with im hopping to be able to keep up with 6sp rx8s on the track with the setup maybe beable to get about 280 horse out of it
