I went back to the track today. combo is the same except I now have a 10'BTE converter, flash 3800, footbrake 2500-2600. Weld wheels 8's in back, 4.5-5in, in front. See if you can guess the best time I ran was. Last trips times are listed below. they were ran with a sorry 1900-2200 summit stall, basically it is a stock converter.GOOD LUCK with the guessing.I'll post tommorrow.

There is somthing suriously screwed up with the timing system there. No way can you run a 12.19 at only 107 with a 2.0 60 ft How can you run 114 one pass and only 107 the next are you letting off before the line? I have racing many different car at the track and the #s not add up.
There is no telling how much quicker it went becasue your traction is all over the place but it should be 3 tenths quicker if you could get it to hook.

Sounds like nitrous oxide to me,,,and its a light weight Camaro. 11.90-12.00

The problem I had with consistancy is that on my first trip I could not floor it off the line, or my car would bog down, it almost died on the first pass. I had to play with it and give it the gas slowly. I also shorty shift from time to time, on accident, so I probablly short shifted on that pass. Also I went into valve float on that pass because I had a rocker nut back off. So I did let off on that pass.

Okay, passes are in order. I did have a problem with traction. The BFGoodrich Drag Rad. didn't like the 3000 footbrake take off that I did. I am more than happy with my BTE converter!!!!!!

the reason for the inconsisitancy is the air pressure-never ran the tire with converter before , I didn,t know what air press. to run, was constantly letting it down the whole night, I finally stopped areound 18,around the 3 or 4 pass. I also could not leave at 3000 like I wanted to. I was playing this the foot brake RPM to try to find out what was the best. 2000-2500 still don't have it quite down yet.The car was spinning just a little bit on all passes though, just a little. The jets were also changed through out the night. But we still have more tunning to do . best time was with 70 Fr. and 73 Back. I think we are going to try 68 in FR. and 75 in Back next time. I am also going to bring some 28 in. slicks. I was running out of gear about 3/4 of track. I was going through at about 6500 maybe a little more RPM. The faster I got, the faster I hit third, faster I ran out of gear. I also managed to pull the wheels a couple of in. My dad told me one timee it looked about 3 in. both tires.
I STILL haven't hooked up my NO2 yet, but I have to get some tires that will hold first, or theres really no point. I swear I am not making this up, or spraying. So hows that for a little small block?
Adv. specs.
Converter 370$
foot brake 2500-2600
flash- 3800
anti balloon plate
Actually will go 3000RPM foot brake, maybe a little more
Not to bad Huh?

Great times for a 355!! what does your car weigh???

It weighs about 2800-2900 with me in it.

Man that is incredibly quick for such a mild combo. Am I correct in assessing you have picked up anywhere between 4-7 tenths by just the converter/jetting? Were the original times you posted about where the car usually ran prior to the converter? How tight would that converter be on the street?

Thanks

Put some slicks on it. I have found that if i just bring the converter up a little bit like 1800 or so it will leave better than tring to stall it up tight. Your car runs very good for what you have.

I'm reading this, and like, just shaking my head. Granted the car is light, but it goes like stink!

The first trip was the first trip with this motor. 1900-2200 summit stall, basically stoc converter. The jetting would not be what I think gave me the faster times, because I was running 11'6's with the jetting the same as before. I did get a home made ram air set up on it though, which I know had to help some. Also I went faster through out the night, because of letting out tire pressure, and getting the hang of it better. But the humidity was getting worse through out the night. I think that I would have ran a little faster if I could have gotten the air pressure and feel of the car alot faster because the humidity wasn't that bad when we first got there.
Howerver I did learn that you can never under estimate what a converter can do for you. I am trying to get head lights in it, and see about affording insurance so I can drive it on the road some. I can really say much about how it drives on the street because I haven't really done it yet. I am going to try sone 28 slicks (MY Dad's) because of traction and I am running out of gear about 3/4 of track.
