I've accidentally ran 25lbs of boost on the street on 93 octane. It didn't break, but I consider myself lucky. I'm sure I could make some pulls on the dyno with pump fuel and high boost as well. But why risk damage to a 15k dollar engine (more in your case), for a few more dollars a gallon?

You always bring this up about pump gas, but never answer when I ask what your car has ran at the track on 93 octane?

I'm guessing it's because you either havn't ran it, or it didn't put down a good number. Either way, I think once you get it to the track and start leaning on it with 800+rwhp and 93 octane, you'll break something sooner than later.

Ever since I got the car back, I have been doing small tuning adjustments like, removing the electric water pump, installing gauges, installing extreme torque arm, tracking down a noise from the rear that ended up being a bad end link rod on the rear swaybar. I took the car to Darlington about a month ago, and ran it on the track, and the car ran what I thought was terrible numbers, 12.47@115, spinning the tires 30-40 feet out of the hole, running on Nitto 555. I ran the car 14 times in a row, one right after the other. Now lets look at that, that is retarded for a car that dyno'd 800RWHP. Right?, No Question. The car was falling on its face at 5500rpm. Now, put that thought on hold for just a second. I am probably the most unexperienced drag driver on this forum. I had been driving the car around, and it felt strong and I could not tell any difference, because I was not used to it. The fastest thing I had ever driven was my Northstar Fiero. So now back to the other piece, While at the track I let someone else drive the car, and when they got out, they said take it home and lets take a look at it. When I installed the boost gague, I did not install it right, my gague requires calibration for sea level, and I installed the sensor in front of the throttle body thinking, it would be a temp location, and I would be able to see the boost reading before I closed the throttle. Man was I wrong, i was getting boost reading over 23psi. We both know that my F1 with my 3.85 pulley and 8 inch crank pulley, that is not possible. Got back to the shop, hooked up a analog boost gauge and found out that I was missing about 6 psi, because when we originally dyno'd the car, the car had made 10psi. Upon close examination the intake plumbing had come off the front of the blower at one time and I had put it back on, but when it happened a small piece of plastic had got sucked up into the blower, and tried to come out the blowoff valve and got hung up causing the blowoff valve to let all of my boost out. The car was dynoing at 400RWHP. So, now if we look at the numbers of 12.47 @ 115 on 275/45/17 Nitto 555's Im going to say that is not too bad. With me not in the car, the car weights 3520. I weight 230.

So where are we now. Now we are back to where we are suppose to be with 822RWHP, its a supercharged car so I am not sure how I could have an explosion of boost like I could if I had a turbo. The SC is not going to turn any more than the engine is going to turn, so there is no danger of an over boost problem.

I am on schedule to have Marshall Racing here in Indian Trail, the person that did my Chromemoly Roll Cage, to finish the front of the cage, I will have the airride supension and new seats with racing harness installed before the end of Jan. Plus I need to come up with the money for a helmet. Because I dont do anything half-a@@ I have to have the best that there is. So sometimes I it takes me longer to get stuff. Why did I go to the track last time without all of the safety equipment? Because I felt safe driving the car, on 400RWHP, of course it was not a problem, I was used to driving it. Now that I have had a couple of chances to get on it, I can say this, OH MY GOD, I now can say without a shadow of doubt I can tell the difference. The car pulls and pulls and pulls. The front of the car looks like it wants to come up when I get on it. I am really depending on some friends of mine here to help me learn how to launch the car. When I was in Darlington, I was asked several times by officials, where was my helmet and belts. I kept telling them that the car was not going fast enough. I really want to put the track thing to rest. As soon as the changes are done this month, I will back to the track. Most of the calculators I have looked at say 9.66 @ 141mph. I guess it really depends on if I can get it to hook up.

The reason that I keep bringing it up, For some it is about dyno numbers, for some it is about drag numbers, for some it is about driveablity, for me it is about conquest of doubt. So many have said, it was not possible first on pump gas, then with the stock computer, then that it wouldnt be streetable. I had always wanted to design my own engine, and this is the end result. It is all about making the engine as efficient as possible, today my car make over 2 HP per cubic inch at the crank. I just think that we as a community need to redefine what is impressive and what isn't. You know and I know that with Race Gas, and a little pulley mod and minor tuning, 1000RWHP is there. It is just like my friend with his 2000 Vette. He called me to tell me that he had hit the 180mph mark, and I told him that he had been 20mph from the promise land and cut it short, so he went back and hit 203. So I feel the same way, I am 130HP from the promise land and being able to do it on pump gas is where it is. I could run nitrous or race gas, and be there with no problem, but the real challenge is making it happen on pump gas without knock, or retard from the PCM.
I want to belong to that club, the 200MPH club. According to all calculations, the car is capable of 243. I hope to get the car to the salt flats this year, and see if I can hit the 200mph mark. I just have a different set of goals than others. Sorry for the long response, but I thought I owed you a response.
