MR509 is here.

[MR509]

Hello to everyone.

My name is Billy covitz and i live in virginia, richmond area.

I have been drag racing Buicks, olds, ponts in the footbrake class and have done very well with it.

Now i have a dragster and it will be my first year in top et class.
Time to try my skill at the box.

Its a 225 inch race tech dragster with a 509 gen six block and it has dart aluminum 345cc pro1 heads and a dart intake with a 1150 dom carb.
Also a power glide trans and 410 gears. I hope it will at least run into the low fives in the 1/8 mile.

Thanks Billy.

[Awesome Bill]

The heads are way big, the carb is way big, I doubt it will run 5.20's. The only thing you have, is that it is light. I will bet though its going to be down on power. Even @ 7500 with a VE of 100%, which you won't get, the engine will only use 1100 cfm and thats only @ 7500 rpm. Shift that thing and it will fall over like a tree cut @ the trunk. I would recommend a converter somewhere around 6200-6500 and that will keep your 7500 goal shift point from falling back to far. CAUTION, your slippage factor will be up there and you should use a 4.56-4.88 gear for the 1/8" This will help the little engine a little better with those big induction parts.

Awesome Bill.
This motor set up like this run 5.50s in a 3000lb camaro with a 456 gear.
My converter is a 5500 to 6000 stall.
I will let you know how it runs in the next week or two.
Thanks Billy.

What cam, heads, compression, and intake are you running? Running gas or alky?

Don:cool:

[Awesome Bill]

that has got to be the best 509 I have ever heard of. That makes no sense. the would put that engine in at about 870 rwhp putting the flywheel well over 900. Don't think I have ever head of a 509 with that application ever running that fast without a little help from the NOS tank. But, if it run that, @ 3000 lbs, you already have your e.t. That should surely put you where you wanna be. You should loose about 5-7 tenths. That puts your little engine around the 2hp per cubic inches! Thats never been done with that stuff out of the box and very big ever. What was your mph and rpm crossing the finsih line and what size tire did you have? Great engine.

Yes Awesome Bill.

It went 5.26 @ 131 MPH in the 1/8 mile this past saturday at richmond dragway.

Its a 509 with dart 345 cc pro 1 heads.

14 to 1 compression

Dart intake and 1150 dominator carb jetted 98 square 37 squirters and 50 cc accelerator pumps. No power vavles.

cam is a crane cam solid roller. Valve lift is 714 intake and exhaust and duration is 282 / 292 @ .050 with 1.70 rocker ratio. part # 13r000646.

Trans is a super glide 3 with 180 straight cut gear and a 5800 to 6000 stall converter.

Ford 9 rear with strange housing and axles and 410 gear ratio.

I am leaving off the trans brake at 4800 rpm's

60 FT time is 1.20

Timing is set at 36 will try 38 next week.

I am happy with it.

Thanks Billy covitz.:):):)

[MR509]

I am running this 509 motor on 112 race gas.

Thanks Billy.

[want-a-be]

I'm betting it will like the timing. Without knowing what the chamber was decked to you might need the timing to get across the dome a bit. PLus...you might be a tad rich. Liking more timing kinda points in that dirsection also.

60' seems a lil' high but could have been a cold track this time of year. Might play with some tire pressure there. I would have expected closer to 1.12 ish. Could try leaving a bit closer to your stall.

What RPM are you shifting at? I bet you have this in the high 4s before the year is over. What bottom end are you running in your engine? Whats your trap RPM?

Thanks, Don :cool:

Your et is very bad for what motor you have and what it should be running @ 1800lbs, the math don't agree with the 3000 lber running that fast and now in a light car runnng 5.20's. Anyway, I agree with Don on this one, you do not have enough engine or I should say compression,RPM and the use for 112 @ 36° timing. You will see a difference in around 40-42° timing with no problems. It will pick your slow 60 ft up a ton. Your really only down on the 60 because your heads, carb and cam are out to lunch big. Once the snail can get moving, its not to bad. This is a classic example of what big heads, cam and carb will do. It would behove you to use a 1050 or even a 1000 cfm 4150 on this one and watch what happens in the 60 and the shift recovery. I would recommend a 110 or even the VP red107 stuff with your engine @ 36-40° unless you know absolutely for sure your compression is more than 14:1. We cc every thing to know for sure what fuel to use and then Dyno it to see where its done making power. You can do that at the track on a good test and tune day and most of the time dial it in in a month or two if its a brand new combination. The 320 and the 345 head is actually big for this engine also, but would of make a much better package if you were swinging a 4.6 bore and be a 533 or the best would be to hang a 4¼ crank and make a 565 out of it.

You have what you have, so make the best of it with little things and you might get it into the 5.0's with proper tuning and trial and error. I would get a video of your 60 foot, get a sandwich and a drink and sit down and watch it. You will be amazed at what you will learn in slooooooow moooootion. You most likely need air pressure not less. We normally run about 8-10 on a good track 6-8 on bad tracks 14x32 or larger tire ofcourse. I do assume this is in your dragster.

Your an old Pontiac Olds man, why do you think they have so much torque? Its most for suredly a big head!

[MR509]

The 509 motor is being shifted at 7200 rpm's.

Rear tire size is 33.5 x 17 x 16 Goodyears.

Thanks Billy.

[Awesome Bill]

what is the rear tire pressure?

[MR509]

Tire pressure is 7 to 7 1/2 psi.

Front tire pressure is 35 psi.

I will set the timing up to 38 this week and see what it does.

Thanks Billy.

[Awesome Bill]

Do be worried about trying air pressure changes and then seeing if it helps the 60. Most times your air pressure gauge does not read that well and 1-2lbs of air can help. If the sidewall rolls up, the car actually goes backward first then jumps ahead. Slooooow Moooootion video will yield more than you think. Of course, you have to be able to duplicate your runs the same so a good side by side comparison can be doen. Have fun.

[want-a-be]

For a car that light 7-71/2 seems a bit much. Like Bill said, if your gauge is 2 lbs off it could even be as much as 9 or the other way. I usually look at the side wall to see if it's looking like I think it should. IF not I start comparing air gauges.
Easy way around this is to always use only 1 gauge and learn it's charicteristics. off or not once you find out what the car really wants you'll be ok.

LAter, Don

[Awesome Bill]

the only way around this is to use 1 gauge all the times. we forgot our gauge years ago in a race and the boy doing the air pressure borrowed the guys gauge from him and when he checked the tire pressure is was 2 lbs over. He adjusted the pressure like he normally does right before we race and the car went into tire shake, recovered and then was like a snake all the way down the track because of the side wall rolling back and foruth or side to side. When I got back, the tire pressure was 1-½ down and I asked what happened and that was it. He forgot our gauge. 2 gauges don't mean squat. Use yours and don't even think its right, just use it to were you 60 is best and go with that pressure. Goodyear, Hoosier, MT they don't actually know whats best, they just recommened. We always try to run a pretty stiff sidewall as far as preussre goes. The tread only keeps the tire and rim stuck, the sidewall is what launches the car and keeps it stable going down the track. Sidewall integrity is critical so it air pressure!

Hi, Guys.

Well this is the fifth week i have been running the dragster and off the trailer it runs a 5.36 at 130 mph.

Then the second time run it goes 5.32 at 131 mph and runs 5.32 round after round.

I love it, Its deadly.:D:D::):)

Thanks Billy.

[malihoochie]

Mr509 - glad those heads are working for you. I too would have initally gone with a little smaller runner size head, but hey! don't let me or anyone else rain on your parade. Your car seems to be doing well and if it is deadly consistant like you say, it will carry you to the winners circle on a regular basis. Keep having fun with the car and keep us up to date on how you do. :)

[Awesome Bill]

If deadly consistent and slow is what your after, you have it. Those heads are really killing your power and torque. But, like you said, you will have a very consistent et. Your best e.t. equates to about a 8.42 @ 162. This puts your mph way over e.t. for a dragster, proving your heads are just about to get really going and the race is over. If you wanted to pick up some serious e.t, put a set of 4.88 gears in that thing, (1/8 only) and watch it dip into the very low 5's. This will keep the engine in a better curve, (upper) and recove quicker in the shift. Try shifting it around 7600 also, that way it will not fall back into the lower rpm range and take longer to recover. You should be running 5.0's with no problems even with the larger head. Have fun and just keep adjusting different things and weed out wear it does not like to be.
