Not sure how that might work at your end but at my end something on the Drag Times website is messed up. Typically you pick a track and the weather data pops up. Pick the time of day and that data is entered. Then you use your time slip results and it'll correct to sea level.
I've had my share of racers argue that it's not the way to race. Fair enough. But what I used it for was to compare my East Coast time slips to my Western Canada results. Once corrected, it was plain to see that the cars performance was the same, just crippled with poor conditions.

 

It was a great day of racing yesterday at the Humboldt County Dragway. I made it to the semi finals last night, where I got beat. My car did it's job in that round, but my opponent had a better reaction time on the light and got the win. The air today was way better than it was 2 weeks ago, so it was awesome to see how the car would run with the new torque converter in decent air conditions. (2,800 ft DA vs 4,477ft) The car ran the best it ever has! It ran 7.23 @ 94 mph 5 TIMES today. It was ridiculous how consistent it ran!

 

thats freakin awesome; you always seem to do well going rounds. Nice work
Also, the consistent timeslips 5 times in a row is a great achievement.. and its fast too. My best all motor passes are right there at 94-95 mph in the 9th and usually 7.30's 7.40s so I know that it has got to feel strong for you going down the track. I love that yours leaves with both wheels in the air too, makes for killer photos.

 

UPDATE....

I got the win at the track the last 2 weeks in a row!

 

Also, a few weeks ago, I got lined up against a new C8 Corvette in time trials. Here's how that went....

 

Good job!

That car runs even better than it looks.

 

flat out just awesome !

 

Thanks fellas! I'm having a BLAST with this thing!

 

I haven't followed this in a while. Nice results!
As a refresher, you did the gear swap correct? What for what?
And I saw a new converter is in play. Any specs to share?

 

Thanks!

Yep, i did the gear swap. Went from a 3.90 to a 4.86

The converter is a Monster brand, 10", with a 5,000 stall

 

5000 stall and a transbrake! I like it!
Are you seeing 3rd gear with the changes?

 

Oh yeah, I'm in 3rd gear for a ways, now. I'm crossing the traps right at 6,100 rpms in 3rd gear

 

Excellent! That was the plan along.
Well done.

 

Another question: What's the shift recovery like with your new converter. Shift at and falls to what RPMs.Reason for asking as I've a new converter too although yet untested. I was looking for something that will keep the engine in about a 1500 RPM window even with the wide 1-2 split of a 700R4. Shift at 6200 (overspeed to 6500) and hoping not to drop below 5000. That for me would be ideal.

 

My shift light is set at 6,400 rpms. From watching in car GoPro videos, I'm at around 6,700 by the time I bang the shifts, and it drops to 5,800. It's nearly identical for the 2-3 shift as well

 

my Edge racing 3400 converter had real big shift rpm drops in between the gears. The 2 year old Yank converter is way better with keeping rpms from dropping in between shifts. I can get exact numbers off some old datalogs if needed, and it just "feels" right at the shifts too.

 

While in discussions with Andre at Edge Converters, I believe he said shifts should fall to about 5K from 6500.. One thing I do remember is his emphasis on efficiency. That meaning not a lot of top end slip so more MPH. Whether that translates into less stall or poorer shift recovery remains to be seen. Further testing is imminent as I'll be back at it this weekend. It's rated to have a true stall of 3800 as seen with a transbrake. Foot brake stall should be about 400-800 RPM less.

 

I'd be interested in any data you could provide.

 

I just had a dream night of racing at the Humboldt County Dragway....

I got the win in Sportsman for the 3rd week in a row!!!

And I also took the win in Mod ET!!! That's my first Mod win!!

The car ran it's number all day long, and I couldn't be happier!!

 

I think we've the discussed the prospect of some 1/4 mile racing but the tracks are too far. That said, is your interest growing?
Not sure how your new gearing would play into that though.

 

It would sure be fun...but I think I'd need my 3.90 gear back, or at least something in between

 

dude, 3rd week winning in a row! thats killer! You are indeed on top of your game right now



so, just to answer this question a bit, this would be a quick comparison from two datalogs where the car was all motor, 1/4 mile, no-nitrous, and with two different converters only. If you want some deeper details, I know that I typed out a bit about each pass on my build thread, so scrolling back to the corresponding dated pages on that thread, you can find the full timeslip info, a datalog, and a video for each one. link if needed by anyone later on: https://www.thirdgen.org/forums/tech...g-install.html



But here is basically the best way I can show the difference in the rpm at the culmination of each shift. At the end I will show the "overlay" view.

May 1, 2022 - Pass #1
Edge racing 3400 Converter
Car ran 11.73 at 115.7 mph with a 1.62 sixty foot
Foot-braked from 996 launch, converter flashed at 2,892 rpms. Shifted 1-2 at 6571 rpms and it dropped to 4818 rpms (a drop of 1,753 rpms!). Shifted 2-3 at 6,386 rpms and it dropped to 4,883 rpms ( a drop of 1,503 rpms) and went across the finish line at 5,949 rpms.




October 16, 2022 - Pass #4
Yank Performance PAS-3800 converter
Car ran 11.69 at 114.4 mph with a 1.54 sixty foot
Footbraked to 2,564 rpms and converter flashes way higher at 4,856 rpms. Shifted 1-2 at 6,450 rpms and it dropped to 5,232 rpms ( a drop of 1,218 rpms). Shifted the 2-3 shift at 6,285 rpms and it dropped to 5,331 rpms (a drop of only 954 rpms). Crossed the finish line at 6013 rpms.






Took the time to figure out how to overlay a comparison of these two runs, and its worth examining.

 

Thanks for that.
I can relate to what a difference a converter can make. Off the shelf TCI with a stall indicated as "1500 RPM over stock" compared to a Yank SS3400. That step function change I hope continues with this new converter, an Edge 3800 from their Street Edge offerings.

As for our OP, Dagwood has seen a jump in performance although I believe as described it's gearing and converter in one go. Seeing though as his stall is now 5k and the shift recovery appears to be excellent, there's a lot in that converter.

What I dig the most though is that the two of you are racers. Somewhat different approaches but still track proven with data to go along with it.
I hope to join that club again soon.

 

I finally got the correct Dr. Feelgood lettering for my car!

 

Looks great!

 

I see something more than some door art that's also new.
Care to elaborate? Yes. I'm referring to the "bug catcher" poking through the cowl.

 

Yep, that's also new....

So the old air cleaner that was on the car had a huge drop base on it, and was still smashed against the hood. (The top of the carb isn't much shorter than the cowl hood). There was also like 1,000 dents on the bottom of the air cleaner base from the throttle linkage hitting it.

So, problem solved 😁

Also put a set of Centerline ConvoPros on it

 

Well, cold air certainly won't be a problem.
Looks like you're running a single intake and a spacer. That'll stack things up for sure.
I've also dropped base filter case (1-1/4" I think) and I've just enough room for a 4" element. That's on top of RPM Air Gap so it's not the height of a single plane. Also a glass hood that's open to the underside of the cowl (which is about 1" to 1-1/2").

My only thought is whether your smallish air filter has enough capacity for your HPs. K&N has a spec on their website.

 

The car runs a little harder grabbing some fresh air. Ran a personal best last Saturday, but unfortunately broke out while doing it. 7.13 @ 95.32 mph!

 

Nice 60'. I'm hopeful I'll be close to that but that's a stretch.
Nice reaction time too. Nothing like double zeros to make your day!

 

Thanks! The car ripped a best 60' last weekend of 1.46 and also ran a 7.12

Damn thing is running hard for what it is

 

A couple launch pics from this past weekend....we had absolutely horrible air last weekend. 3,000 ft DA, 88% humidity, and maybe 70 degrees. Car was running .2 slower

Oh, and I'm sitting 2nd in points for Mod ET class at the track!

 

I just put the car on a diet. Gutted the interior, aluminum race seat, and removed the rear bumper reinforcement. It still has the door panels, power windows, etc. This weight is with the fuel cell completely full.

 

Getting under 3000 is the ticket, and as we all know, taking weight out is the same as putting hp in. The 'old-school rule of thumb' states that removing 100 pounds is worth a tenth in the quarter.

 

What did it weigh before the diet?
I'm curious too about how much cutting out the door bars would save.
And then there's Optic Armor. I've been looking at their light weight hatch glass.
If I don't build something streetable out of the spare chassis I have (82 Coupe) I've considered building a stripped down race only car. Lightweight is king!

https://www.opticarmorwindows.com/ap...urer=Chevrolet

 

Heres the weight before...

 

Almost 200 pounds. Not bad. I can feel that amount of difference in my car when there's a passenger.
Imagine being at 3600 lbs! That's my current race weight including driver (200 and change) and about 8 gallons of fuel.

 

Well I have a few updates since my last post. I have been leading points in Mod ET at my track for the past 6 weeks or so. I've been in the final round the last 3 races in a row, but lost all 3 times. Last Saturday I had the race won by 2 car lengths, but broke out by. 0002 seconds, even after tapping the brakes. Ugh.. Anyways, the car has set a new personal best, too... a 7.07 @ 95.79 mph. The car is gonna get in the 6's with some good air, for sure. And I also removed the hood hinges and latch stuff, and installed hood pins. Shaved another 13 pounds

 

The car looks as good as it runs!

 

Thanks man! Depends on what 8th to 1/4 mile conversion calculator you use....it should be a very low 11 second car in the 1/4. Knocking the door on 10's. She runs pretty good for no more than it is.

In good air, it shouldn't have any trouble getting into the 10.90's. It'd do it now if I wasn't 250lbs

 

Optic Armor is a good product. We have it on our Firebird for the windshield and hatch. Literally looks like glass.

You can skeletonize the front bumper mount and cut the door bars out for more weight savings. While the front fenders are pretty light, aftermarket replacements are a bit lighter. Fiberglass units are just a hair lighter, too. Not sure I'd trust the hood lifts on a 'glass fender, but the hinges mount up with zero problem.

Nice car, BTW, and great times. That 1.4 60' time is awesome!!

 

Thanks man!

 

Well done on all counts.
While our cars used to look the same you're far away built better as far as drag racing goes. My hope would be to break into the 7's with all the new bits. Ultimately, I'd call it a day with an 11 second timeslip. 11.99 would do it for me.
The transbrake is game changer for sure. Your 60's are envious. Soa re the wheelies!
As for the 1/4 mile, it'd be interesting to see how your current gearing would play out. 10.99 should see a trap speed better than 120 MPH.
As for weight...
Optic Armor is high up on my wish list. That said, the list is long if I keep at it.

 

Step away from that breakfast biscuit every morning, and in a week's time, you will have dropped enough calories to lose a pound of body weight. Do that for a year, and you'll be down to 200, will look better, will feel better, and the car will run faster too!

 

I'm down from 280 since February. Im on my way! The problem is that I'm 6'5" tall, so around 230 is my goal. I found out I was type 2 diabetic, and got on Ozempic...and its helping my weight, A1C, and blood pressure

 

Good deal; stay with it. Being overweight is the likely cause of probably half the health issues in this country.

While I'm not a doctor, I've been involved in the fitness and nutrition world for over 30 years, and still research everything related. If you're going the Ozempic route, keep a close eye out for any occurring side effects, and if you see any, get with your doc pronto. Good luck!

 

Thank you! So far I've had zero side effects...but the doc just upped my dose

 

As long as you're sticking closely to your attending MD's orders, you should be OK.

 

Well I got in some pretty good air last weekend...and ran a personal best 7.0324, and a personal best 60' time of 1.4502

Still no 6's yet

 

Excellent!
Do you have any weather data related to your "good air"? This is something I follow closely as it's a huge performance difference between good air and bad.
Case in point, last time I raced (which was decade ago!) I was comparing a 4000' DA to a 500'.
More than half a second in 1/4 mile and 4-5 MPH. I thought the engine was hurt but after a quick correction using some online tables it all reconciled to the same ET and MPH.
