Front Engine Dragsters / staying cool in summer heat
« on: July 19, 2020, 05:28:54 AM »
Has been a topic on other sites,figure hey might get some tips from guys here. I also figure we have a older group here than some other sites and has to effect us more than younger guys(lil punks). So what do you do or wear to help handle heat while wearing firesuit and sitting in small oven while straddling a heat filled trans mission.

Front Engine Dragsters / tire speed vs low gear ratio
« on: June 20, 2020, 08:47:30 AM »
Maybe my thinking is off base.After 7 months of job I am doing its highly possible.

 Wouldn't a higher(lower number) ratio give you more wheel speed at the hit?Provided you have enough power to get it rolling. Part of another thread and did not want to derail it. I had advice from a old guy in Kansas not to go 1.80 low but rather the 1.69 low because of shake. Hard to argue with those guys. LOL  So far only shake I have had was from stupid tune.which goes back to under powered thing.Always a probleM. NEED MORE POWER!!!!!!!

Roo Man's Room / anti rotation connection
« on: June 13, 2020, 05:32:57 PM »
 I don't guess there is any rule on how anti rotaion has to be bolted.
I need more ground cleartance. About only option is  lowering rearend and motor in chassis. I will nee to rework anti rotation which is wish bone under housing bolted to two tabs. I will have to remove tabs,welded bungs into middle rail under seat and bolt thru it. this will allow me to drop rearend 1" and get little more ground clearance at motor plate. I will also have to remount rearend which I hate but it is what it is. Lowering motor is no big deal except remaking motor front motor plates and cuttine and redrilling rear or m id plate.
I figure to get few more test in before heat get stupid hot and so rework whle it too dang hot out to be wearing a 20 suit and waiting on idiots to run a 500 hp car down a track they spend 10 minutes removing anything on it any where,

Dan Dishon's Transmission Den / welded reverse clutches?
« on: June 10, 2020, 06:36:31 PM »
Ok. I take car out  last weekend.First time this year because of over blown virus crap. Car does long hard burnout,backs up fine. I stage and when I let go car moves but feels more like moped than a race car. I hit throttle shove 2nd and roll on down track.Go back to pits.Look things over.Appears  cable out of adjustment and car might have been in between low and high. Second runa bout the same excpet less go.

I get home and once I get it down only thing hurt is reverse clutch pack,By hurt I mean it is nasty black and welded together. Its not low gear band and that is 150 bucks good thing.Its not high gear clutches,probably because I have two full spare sets. I knew I should have bought spare reverse clutches.

So how the xxxx did I fry reverse?

Matt Shaff's Engine Shop / HP build level
« on: May 09, 2020, 05:07:14 AM »
Reading thru some old post and noticed a lot had a HP rating on various pieces. WOndering how most approach this.

You can build a 700 hp piece using stuff rated for say 800 Hp,but have choices of higher rated piece.

Cranks are one example. Transmission p[arts is big example.

Me like to buy most over rated part I can afford and most of time stretch the afford if it will destroy other parts or my car.

My motor is kind of example. Its old parts(almost new stuff) that was designed for fuel cars 20 years ago. As strong as TF stuff now no.Stronger than most 1000 hp motors by a long shot. I almost feel guilty using it such low power out put. Only doing so because I could afford it.Two short blocks sitting in corner aging is pretty cheap.Plus old technology brings 20 cent on dollar and not buying much of a crank for 600 bucks. LOL

Front Engine Dragsters / nitro supply and price
« on: April 12, 2020, 06:28:05 AM »
Wondering how all the tension with China is or will be affecting the supply of nitro and the price of it. To my understanding(maybe off) all of our  Nitro comes from China. Hopefully bad information on that. If true is time somebody start up a production facility here. The crap with toilet paper we need our nitro people.

Roo Man's Room / cable thru chassis
« on: April 05, 2020, 03:00:04 PM »
 Going to have to ut remote power shut off on car,rules are rules. Would like to run thru upper right part of main hoop dow to fron of motor and to switch which is about 18" foward of motor.

Question is if I weld a tube in hoop just past radius and run cable thru it then exit in front of motor thru upper tube  and place a what ever you call the piece around opening to keep tube from failing.Have brain fart right now. Is that legal? I know spec stops at mid plate just wondering about opening in main hoop with tube welded into it.

Jon's Wheel House / durometer reading on tires
« on: April 05, 2020, 12:53:23 PM »
Was just checking tires on car to see if any change in durometer reading. Got me wondering what reading on other brands are.My M/T are 50 average reading and fairly new run wise. I know few have said they had problem getting wheel speed with Mickeys.Thinking maybe harder compound works better for some.

Anyone who check durometer reading on tires from time to time .Please chime in with info on whats working or not working for you.

Front Engine Dragsters / all loaded up and no place to play
« on: March 24, 2020, 05:14:23 PM »

   
Some problem will remember a post I had last year about every time I started to head to track something came up.Either weather or a chance to go tune on a blower car.I love working on blower cars and getting few bucks towards FED made it almost no brainier.

Now here I sit with new trailer that is about 1/4 equipped and gaining. Car is ready to rock out and now even has new rods.Last part was just a peace of mind thing since others only had 5 runs,but that 5 runs with 11000 rpm shifts and 52 lb boost.

All loaded up and no place to go play. Really starting to think somebody is telling me.Hey you have cpl weeks now strip it down and find out why you keep running into this wall that's here to protect you from you.

Spud Miller's Cave / nitro mixture with 02 aensor
« on: January 04, 2020, 08:10:49 AM »
Spud,

 A question came up cpl days ago in a bench race session. Lot of folks running o2 sensor instead of EGT now days. How does a nitro mixture effect reading and could o2 be used to tune with running nitro?

Spud Miller's Cave / electric primer pump ?
« on: November 06, 2019, 04:03:23 PM »
Ok . I have a facet pump hooked up on injected motor using for primer system. Car cranks fine after little tuning. Use for cranking only right now.

Issue I think I am having is when shutting motor off. I pull fuel shut off,motor revs up as should before shutting o0ff,except it keeps running and running(no batteries here). I am thinking the vacuum maybe pulling fuel thru the electric pump. Pump is about 12" from main line from tank and mounted low so as to keep it wet for easy priming.Line from pump goes to a jetted line that's in middle of injector with 4 spray holes drilled in it that spray up ward and mix with incoming air.

Anyone have issue with fuel being pulled thru pump?
