There are a lot of rocket scientists out there so be aware! lol

You are correct like I stated on a big DP carbs the booster signal drops big time while launching off line. Specially if the gearing is tall or the car dead hooks and there goes stalling a few seconds before finally charging fast, then it is too late when the guy has a fender or more on us!

Thanks for the info.

That is good and imagine many people build 9:1 to 10:1 max and giving away free power!

Thanks you for reminding me about that 500 2bl carb! lol It did have that REO pump now that you reminded me. I went to that when I was a kiddo to slap on my 2v intake manifold and it did gain! lol

@@benalamedaracing2765 when I had first put a 302 in my mustang, around 1988, It was a two barrel bone stock, I put on a 500 2bbl REO carb, headers cherry bomb mufflers, retuned the distributor curve, and ran it. Lol I was just a teenager so it was pretty fast to me, in that little light car.

@@AmericanThunder It would have been a light car specially with a fiberglass hood and battery in the trunk! lol

@@benalamedaracing2765 yup! If it doesn't make it go faster, it's just excess weight. lol

Thanks for confirming our belief in the superiority of Annular Boosters and I believe you when you say it takes off hard! Could you share a background on your engine combination like heads, compression and cam specs?

@@benalamedaracing2765 Sure, it's a Mopar 440 based 505ci stroker. Edelbrock Performer heads 84cc combustion chambers, I deshrouded the valves as best I could, wound up at about 86cc. I also opened up the "pushrod pinch" on the intake runner as far as I felt safe. The heads are far too small for 505ci, but work very well on the street because of the fantastic "Velocity characteristics " you speak of. Static CR is 10.8-1. Custom spec Bullet Solid roller 254/260 @.050 .585/.585 lift on a 109 lsa. Trickflow single plane, 4150 flange. 1966 Satellite weighs 3,580 with me in it. 9" 3,600 stall converter with 4.10-1 Strange "S60" Rear end on a 28" tire. So much fun on the street !! I need more practice at the track. Only had it out once since the 505 build. 7.79 @91 mph in the 660. 1.72 60 ft. Much room for improvement. Cheers 🍻

@@Torquemonster440 All sounds good and somehow it feels 3500 stall or thereabouts with 4.10s seems to run super good on a street and strip car like yours. B ad RB engines are impressive and I remember a friend told me he has a 440 in it while it was actually a 383 with the same stall speed and gears. Man I was blown away by that 3.35 stroke big block!

Wow your elevation is up there! You could have gotten 1.5 more points of compression without loosing anything and gains mpg's!

@@benalamedaracing2765 it’s a 4500 pound bronco with 3.73s on 35s, run 91, aluminum heads tight quench, low drag rings. Kept it 10:1 so I wouldn’t have problems down the hill in San Fernando

@@WesternReloader Where do you live? I love the wilderness as I see on your video. I had a home by Pinion Hills very close to Wrightwood.

@@benalamedaracing2765 pinyon hills off 138? I lived in Wrightwood in 1996 and went to Serrano High (Phelan) but currently reside in Frazier Park, off the grapevine

Many miss trying them and usually ends up slower by not trying different things and that is where we find out what works!

Thanks again for your feedback. These is why I explained the issue with "booster signal" stalling with a big carb in real world driving not a dyno- constant roll and stepping on it! I had to explain it clearly and most of the respondents here confirms what I am saying about big dyno numbers contrary to what we see while driving it hard or kind of spirited driving.

Thanks and glad you tuned in!

Glad you like it and would do more tech stuff.

Yes it is basically a test on a roll just like if we are doing 35-45 and punching it! lol . Start from a dead stop and things start to happen different from our rolling test sequence.

@benalamedaracing2765 YES sir!!!

Dale, thanks and I was a loss for words must be getting a Biden moment here! lol

Glad you are here bud!

thanks and hope all is well bud! You in Cali or you took off just like almost everyone we know leaving California for greener pastures!

Like wise sir thank you.

JUst turn it in to expose even very little of it and it will be for the better!

@@benalamedaracing2765 thank you for the tip about the screw on the holley,i adjusted the screw on my 850dp on my 428fe and it not only is more responsive when i kick it in, it also sounds better idling, but i did have to turn down the idle on the primaries.

Thanks Jigger and regards to all in the family!

Glad you like it and thanks for your support!

Terry, thanks again and if I remember correctly my 85 5.0 I did notice had an effectively designed lower air cleaner base! Did a lot of testing then @ Riverside Raceway and came up with mods on the stock 5.0 emissions carb from the factory! lol I wonder if it is worthwhile to go thru that in a video? Should be very interesting.

@benalamedaracing2765 hi Ben I think that would be a good video I can honestly say you make any topic interesting , I always look forward to your videos know matter what the subject

@@terrygrover6440 Thanks Terry!

Absolutely and loosing the velocity on the booster will be a bogging situation!

Thanks Don and those quads are awesome things right off the box! I choose the Holleys modular design because of tuning ease at the tracks, with ever changing conditions that needs tearing down constantly chasing the tune! I have lots of time with the Thermoquads and they are just as impressive and somehow smogged up small blocks still pull hard because of the small primaries and big secondary's with an air valve! Hard to beat them off the line.

@@benalamedaracing2765 Yes. With fixed orifices and having to take the top off on the Quadrajets There is only a few things you can do at the track. Very time consuming carburetors but cheap.

@@dondotterer24 Holley had spread bore carbs but with non adjustable floats which really blew me away because I would have tried it if it had that option back in the day.

Thanks Don and did I explain that real good and clear? Hope so because it was really a guess! lol

@@benalamedaracing2765 yes you did a great job.i know you could do a 3 hour video on things like this. And I would listen to all and take notes. But only a few of us hard core guys. Maybe some day do a live chat inviting people you know that can add to whatever subject. Thanks for all your videos! Oh don't forget I'm a Chevy guy. LOL

That is a good question! a dish piston will act like a big combustion chambers so that is an equalizer. If the piston is made with a dish that mimicks the combustion chamber then it will be superior because Quench is in play here. Normally an engine with smaller combustion chambers with the same compression would be superior.

Thanks and glad you are with me here on the channel.

This racecar ended up with Coast High Performance as their test car and someone bought it and eventually got stolen! Todd i have not seen in a while and the fiberglass bumper you see here in the video is the exact one I bought from Todd years ago! lol It was very light and he sold it to me at a great price!

@@benalamedaracing2765 Ben, This is Chris Huff of then CHP/Probe Industries. Todd and I bought your 67 when we were about to cut up Todd's 67 Mustang. I had just built an 414ci stroker motor for Circle Track magazine and wanted to build a drag car to put it in. You told me you were doing a Fox body car and the 67 was sitting in the back yard. Yes, it was under a tree and I think we gave you 500 bucks for it. Leaves were flying out of it all the way to Hawthorn. I put a full cage in it and brought everything up to spec and did an incredible pain job. I will send you a picture. I sold the car and an enclosed trailer that I got from George Klass to an employee at Probe Industries. And yes the car was stolen from him never to be seen again. Good to find you on UA-cam. Take care, CH

Will do James!

More like 10

I remember those things and it seems to have worked but I feel Hank is correct more like 10hp or thereabouts!

@@hankclingingsmith8707 agree on your numbers.

@@benalamedaracing2765 Probably so, I only ever ran double pumpers with the choke milled so I never worried about it I just thought about it when you started talking about drop bases for the air filter. Weird how certain things make you remember strange stuff lol.

@@williamzoom I am having a Biden moment thank God Trump ain't here to make me look stupid! lol

Your welcome sir and glad you are watching this channel.

Clay, depends on your engine combination. Do you have lots of work done on it or is it all bolt on?

@@benalamedaracing2765 Lots of work done. Actually, I called you about it a year or two ago. Seems to have lots of mid range power. But always looking for more.

@@claytonstoolbox What heads and compression? I remember you but not the details very much.

@@benalamedaracing2765 Older Trick Flow TW heads. Professionally ported. 170cc intake runners. Compression is about 10.5 cranking compression about 185 pounds. Cam 231 and 239 @ .050. 110 LSA Roller Hydraulic. Ed air gap intake. The car has very strong mid range but the top end past 5500 isn't what I would expect.

Thank you Ben! Glad it became even clearer and for those watching that it helps!

Unfortunately still is out of my reach. I got a nephew working on trying to get it back but so far nothing...
