Quarter Mile

I was at the track to race my Chevelle foor the first time but my car didn't pass tech for my dual shot 200 hp NOS set-up.

I needed a firewall between the trunk and backseat.

And so I disconnected my NOS tank and was able to pass tech the second time around. That day, I also didn't have slicks and the spark plugs I had was two steps colder and timing was set at 8 degrees.

I'm driving a 66 Malibu with a 383 Stocker, 10.25 compression that puts out about 425 hp., running 373 gears, 2500 stall and Posi. My quarter times that day was improving at each pass 14.26,14.14 and 13.98 due to bumping my timing to 13 degrees.

I know my baseline will improve with NOS, slicks and 4.11 gears that will be installed. I will also redo my exhaust to make them more efficient with exhaust cut-outs included. I also have pizza cutters for my front weld wheels.

With the enhancements, I am hoping to go in the 11's??? However, I think 2 seconds is asking for alot.

I am currently using a COMP Extreme Cam but it is sorta of average (about .480 Lift Int./Exh, duration 228/228 degrees). Would like to switch to a more aggressive Nitrous HP camshaft or Roller Cam. But I won't do that until I do another baseline check with my little improvements.

car should be running low 13's or even in teh 12's (if its really putting 425 horse). Either your numbers are wrong or your motor is tuned wrong.

well, how new to the track are you? I don't mean to insult you, and you seem to have a good idea what you are doing, but I just wanted to rule out a lack of practice early. What kind of reaction times and 60ft times did you get?

Oh, and, that 425 hp wasn't WITH the juice was it?

Yes, I am a rookie quarter miler. Street racing is my only experience, even then it was only stop light to stop light.

My time slip is slow. I really need practice. 60 ft: 2.412; reaction time sucked: .412; my 1/4 time was 14.14 at 99.24 mph.

Next time at the track, I will have 4.11 gears, use my Gear Vendor unit; open my headers; switch mechanical fan to clutch fan, run M/T slicks and open up the 200 dual shot bottle of NOS.

I am also using a B&M shift kit mated to a Gear Vendor (gear splitter auto six speed) and a street and strip turbo 350 tranny.

My stall is 2,500. The motor is a blue printed 383 rated at 400 HP, 4 inch bore, 6 inch rods, and forged pistons. The carb is a 4150 750 cfm Holley. Currently using a ten bolt with 3.73 gears inside POSI (spool).

At the track, I foot brake to 2,500 rpm at launch and shifted at 3,500 rpm.

Many say I should go in the 12's and low 13's in my set-up as is. Maybe I should shift at 4,000 to 5,000 rpm for the best acceleration?

Any suggestions appreciated. Thanks

Not cool. We don't condone street racing on this board.

You are shifting way too low. Your cam has just started to come in when you're shifting. You didn't mention anything about what heads you're using, if you have stock heads this is where you need some work.

The heads are Dart Eagle Heads, using Magnum roller rockers, 200cc intake runners, 2.02"/1.60" valves. They are not ported or polish.

So should I then shift at 4,500 to 5,000 rpm? Wow, maybe I can gain some top-end then.

If this is real and the rest of your engine is built soundly, you should probably be shifting somewhere between 5400 to 5800 or possibly even a little higher. I would leave the gear venders unit turned off and try shifting at the higher point for a baseline. I am running a bone stock 1995 Z-28 with 160,000 miles and 2.73 rear gear and my short time and E.T. are better than that.

i am no pro, but id say that u ARE shifting WAYY too early lol, in my 305 i shift at around 5,500RPM's, no wonder why your not making any power, your engine is just starting to gain its power then u shift to another gear.
