Been running it for eight years now, solid 10 sec car. Very safe, NHRA certified, passes tech every time and always ready to run. To go any quicker just gets too expensive and time consuming fixing things. Nothing wrong with living life, running a business and having a little fun on the weekend.
Exactly! And even more true if you happen to be fortunate enough to have a vintage HotRod to wrench on and take down the road. Have a happy Memorial Day my friend! B&S
have talked with tom and seen his car. very well built and safe. everyone has their opinion but some of us don't want anything to do with the dog and pony show nhra. i`m running a low 10 sec car and am in that group. I have run much faster until I finally figured out that it was breaking the bank. yes, there are some cars out there that scare the hell out of me but toms is not one of them
I've really enjoyed following Carl's build and his cars evolution over the years. He has a vision of what he wants to do and he is making it happen. I took the easier route to go fast and have a home built 185" FED with one of those "belly button engines". New home built 6.0 chassis weighs 1300 lbs + 80 on the nose. 370 cu. in. SBC on alky, 8-71 BDS street blower, driven @ 1-1. It took me a half dozen launches to figure out what the car likes. After getting that sorted out, the 4 passes I've made were 5.02sec, 4.90, 4.80, and 4.75 sec. @ 146 mph with a best 1.08 sixty foot time. This is with a MSD ignition box and distributor, mechanical flat tappet cam, shifting at 6,400 rpm Rev Limit set at 7,400. Plugs look perfect and so far the valve adjustment hasn't moved. With a little more tuning I expect to see some 4.50s. (if my foot is heavy enough) Not sure exactly what that equates to in the quarter but its sub 7.50 and I'm not sure I ever want to run that much MPH. All our little tracks here in the south are 1/8 mile and I know the 4.30 gear will probably need to be changed if I ever go to a 1/4 mile track. So far it's been fun but I'm not sure how much faster I want to go. I'm 66 and would like to live a while longer LOL. Carl if you dont want to me commenting on your thread I understand. Just delete it or let me know and I will. Hope everyone is enjoying a good Memorial Day.
Absolutely no problem afaulk this thread is for those who build em themselves and want to do it their own way........and its for all my buddies who can't get up here to see me as often as I would like, and for the rest "fuck em if they can't take a joke" pretty simple to me..........
Well almost ready for some paint....... Uggg I hate this shit...................didn't I do this 16 years ago.....
Soo, lemme get this straight, there’s a dragster in the picture right? Sent from my iPhone using The H.A.M.B. mobile app
Still waiting for info from Hillborn Kjell, but should know soon...........I hope. Anyway we will fuck with it till we get it right...........I hope.... did get my belts back from re cert.....Uggg that pisses me off..... anyway Kjell guess its just old age creeping up on me and this is a whole new learning curve, and Im getting slower as I get older.......(just need to get faster) What heat range plugs are you running???? what elevation are you guys running at ??? I'm about 120 ft ele. what size jets and pills???? I started with .044 jets and a .080 pill and went to a .099 still no difference oh and I got a new toy...... something else to add to the equation...... Oh and chrysler fan, thats my daughter from another mother and father.........
Yes Carl, just fuck with it, and be presistant, then it will pay off. Forget about age, hey you are still playing with cars, only big ones funny you ask about the spark plugs, we have upptil now used Chapion C59YC, but I'm thinking of trying the N-series from Champion. Be vare the C 59YC has long reach 3/4", so I have to use a spacer. Where we go racing, the elevation is 139 ft. On my blown (20psi of boost) 290 cid, Hilborn's recomendations where to use 4 x 64A nozzles. Main bypass was set to 4-6 psi with a .070 pill. The leakdown was only about 20% and very hard to adjust. To better controll the amount of fuel on low rpm's we set up the system with a secondary (idle) bypass on the BV. Have the spoole with the hole. @10-15 psi with a .160 pill, (just spacers leaned it out to much when going from WOT to foot off ). With this set-up you will have a low system pressure, according to agood friend, that is how these system are set-up today, as to previous (early days) set-up with higher system pressure. I think these Flatheads with their low CR will allwas be altte tricky to set-up. An Enlish guy raced a flathead with a 4-71 on alky, but with lower boost, stated that he used only 2x64A, so big diffrenses. Hope this could help. KBS
KBS, what makes the leakdown hard to adjust?? When I raced midgets we used the same idle bypass on the barrel valve, main bypass with a pill and then a hi speed bypass as well to control enrichment over 6-7k rpm. the leakdown on the spool was quite sensitive and I was taught to adjust by "flats" of the hex on adjustment rod. instead of turns you used sixths of a turn. I want to say we only had around a 12% leakdown on our motors.
not worried about the leakdown as idle is fine and idle circuit works correct, just gotta figure out what is happening when we go off idle and she is flooding the plugs...................
what exactly is the point of flooding. if memory serves the barrel valve works up to about 1/4 throttle?
I beleive that part of the problem, setting up a Flathead on Alky is the low compression. When I say hard to adjust, I meen that the BV are very sensitiv. As Carl states, the engine is flooding when going off idle, the problem might be that the engine can't ignite and burn the fuel. The secondary bypass(idle), works to around 20% throttle and I think it will help, not flooding to much fuel. Carl, have you tried to lean out more on the main and compensate on the BV? KBS
went as far as i thought on the main from an .080 to a .099 still no help I think 4/ .044 jets are a tad too much for what I have but haven't herd back from Hillborn yet and won't try anything else till I hear back, tired of changing oil........
2 fkn hot to do anything so..... 1960 1966-1974 1989 1994- present Anyone notice some kind of demonic possession ect.. going on here???????
There is NOTHING logical about Nitro! , screws up good parts, ruins relationships, destroys careers and credit ratings , a curse on the wallet. BUT it's FUN WHILE IT LASTS ....I can almost see why junkies do what they do, when I think about- Nitro Fever! Self inflicted , no known cure.
