Front Engine Dragsters / Re: calming the car down on the starting line
« on: November 26, 2018, 07:43:21 AM »
That is a serious right turn there. Mine don't seem to be turning any, but then the car goes right with them on or off the ground. Hoping to go out one more time in a couple weeks and see if I can et it any better. It is at least to the point of being predictable, now I just need to keep it from pushing right. I picked up just over .2 with the timing change, I don't really want to go back with
Mine would drive right all the way through first gear then settle down after the shift. Figured it out when I noticed both front tires were feathered the same way. I should have figured it out with how much I was steering it left to 300 feet or so. Probably needed another 20 or so pounds up front.

I think there was I thread on this but too lazy to look it up.
Any idea what the reaction time difference is between leaving in high vs. low?
I realize there's a lot of variables just trying to get an idea.
I,m interested just not sure its the way I want to go.
Is the soleniod included?

You can Bracket Race a FED and its a lot of fun.
When I bracket raced mine I used a Pneumatic cylinder with a needle valve on the throttle to take a little hit out of it. 1.14 60' to 1.24. No timer on it. Ended up right about where you are ET wise.
I had 14 x 32s on the back with 4.5lbs of air because of bumpy tracks. Car would dead hook and squat down an inch or two onto the wheelie bar and was very consistent.

My delay box allows me to stage with my foot to floor and I had it set to put it on the 2 step .50 sec before the brake release.

A .060 - .070 sound awfully big.  Are they that size because the RPM is low.

We have a track with a short bumpy shutdown near us. I found that low tire pressure let me get on the brakes as hard and as soon as I wanted without bouncing. Low being around 4.5#s.

PTFE would be the preferred hose but I've run rubber braided without any issues.
I cant help much on the pressure question but I don't think its as high as the internal pressure.

Ya, I don't think the cockpit is a good idea either that's a RED thing. I'm pretty sure the heat would be next to unbearable.
When I bracket raced mine on a 80+ degree day you wanted your firesuit on after the third round because the cockpit was so hot just from making laps. I would put a fan in there and cool it down the best I could.
I had an extruded aluminum cooler mounted on the frame just ahead of the starter. No fan on it but I wasn't on the converter very long because of the SLE.

Jon it couldn't get much more confusing and both replies are helpful.
I have an Altered now and I'm trying to race it without a delay box on a full .500 tree. I have a Transbreak button with a bit of throw but just not enough to not redlight.
I also have an MSD Grid in the car and I'm going to try pulling some timing out at the release of the brake to slow the reaction time without killing a lot of ET.
I'm thinking I will start with -5deg for .100 sec and see if it even shows up in the reaction time.

 Are you looking for anything in particular to trade?

Front Engine Dragsters / Roll out time
« on: October 03, 2018, 04:04:32 PM »
If a car 60 foots say 1.25 seconds with a 25" diameter tire. Any thoughts on how long it takes to drive the tire out of the beams.

You can also adjust how hard it leaves with a needle valve on the inlet.

I would think sprag. Your going to need all the torque multiplication you can get.

Well I had a little free time, and with the rainy weather today, it was time to get out in the garage and do a little checking on the dragster. I got it up on stands and stripped the wheels and tin off of it so I could pull a string on the centerline and check where the wheelie bars where hitting. Looks like I was about 1/2 off from center. Any thoughts to if that would be enough to drive the car hard in one direction or another? Also found some slop in one of the upper mounting tabs. It seems the whole had wallowed out, I'm thinking that could have been a part of my problem, letting the bars move. So I drilled it out and welded a hardened insert in the hole. I also checked my tire diameter, they are less than 1/8 different, so shouldn't be any problems there. Anything else I should check while I have the car stripped down? Hoping to take it over to elk creek nostalgia event at the and of the month.
When I had two wheels on my bars I would raise the right side about an inch and it would steer the car to the left. When I switched to a single wheel I would but the wheel about in inch to the left and it would steer it left.
So yes having the wheel off center will steer it by shifting weight. Wheel to left weight goes to the right steers left, Wheel to right weight goes left steers right.

Front Engine Dragsters / Re: Injected FED's launch rpm
« on: September 19, 2018, 10:12:02 PM »
We race on a .4 Pro tree.  i too have a SLE.  When we are both in, my foot goes to the wood, blades crack, to around 5000rpm, and the SLE opens with the brake release.

Almost exactly what I want on mine to do ,except want  it to work on full tree. Don't want it sitting there at 5000 dropping cylinder every other with BV wideopen and holding for 1 to 1.1 seconds.At 5000(2500 engine) that is about 3.5 to 4 gpm .  1 second doesn't sound like much to most,but look at a data download and how much crap happens in 1 second.
With my delay box you could sit there at dead idle with foot to the floor and set the SLE to pull throttle open at any time before the brake releases.
 Or set any RPM you wanted when your foot goes to the floor.
