Altereds / Nostalgia 102" iron 392 hemi Topolino front end question
« on: September 12, 2016, 12:59:49 PM »
Hi guys
Just wondered what your opinions are as to whether I look at my front end spring rate/damping adjustment after last weekends interesting ride. Waiting to hear back from the coil over supplier as to what spring rate is on there, although I think we are running 220lb springs

The car is new out this year and has made 12 runs mostly in the 8's and straight. Yesterday however I did get out of the groove and leant on the suspension more than previous. As you can see it likes to cock a rear  :o

cheers

Sounds good to me, chuffed to bits we sorted it though. We can now relax and wait for three weeks for Dragstalgia at Santa Pod when we will be up against all things Nostalgic, including Rat Trap and the Bradords Topolino fuel altereds.  :) :) :) :) :) :) :)

Update.

Just back from a weekend testing at the NSRA Nostalgia Nationals, Shakespeare Raceway, UK
New nozzles with only one hole positioned at the top were fitted and sorted the problem.
As for the nozzles that came with the used hat, it's anybodies guess as to what they were or used for. All I know is with the spray pointing down to the blower the AB holes were at the 3 and 9 o'clock position and I did say holes! They are now in the trash  ;D
Car ran an arrow straight 8.84 154mph, which is better than expected as the tune very mild + 6-71 street blower only pushing 7psi boost on 10% under.
New car and driver learning the ropes but SUPER  8) 8) 8) WITH THE OUTCOME.

Thanks guys for your valued advise, I would not have been able to sort the problem without your help AND Dreracecar the vent would have caused another problem i'm sure, which we were not aware of.

OK lets ask this now--- the air bleed holes on the nozzle bodies are pointed up? or are they pointed down?
Neither, they are on the side :o which I am hoping and it seems obvious now, is where the problem lie's. Another thing, there is two holes, one either side  :o :o see pics below

they should be pointed up and any residual fuel from the nozzles tiny hole would seek the path of least resistence thru the large hole down lenght of the nozzle body and not to the top of nozzle hex.

 Dont care for the vent placement as you have it, since it is below the highest part of the tank and on the back side, with a full tank under hard acceleration , fuel climbing the back of the tank will seek and find the vent line and exit the tank, with the fitting in the cap or a seperate (new fitting) at the top of the tank, fuel climbing the tank will not affect the venting
Point taken and understood, hence tank out off to workshop some mods and hey presto we have, I think, what you are advising Dreracecar

New nozzle bodies will be at the track for me to fit and hopefully all will be well.
No more fiddling now, loading up and off to the track. I will get back to you next week with conclusion, cheers guys  8)


Draw 3D I hope we have the solution so won't be videoing, the dribble was basically just that a dribble, not under any real pressure.

Latest, fitted an AN8 tank vent and ran the motor, still dribbling much like myself at the moment  :'(
Motor sounding good, shut fuel off and the motor picked up as it run out of fuel, kept gas bottle at 45deg to centre butterfly, all shut down normally then fuel dribbling out of nozzle air bleeds for approx 4-5 seconds  >:(
One thing that did not happen which was there before - the hissing/pressure release noise has gone, so the obvious answer it must have been the small tank vent sucking air in.
So now venting good thanks dreracecar.
But still dribbling

dreracecar, I checked all the fuel lines and pump operation last night, all found to be OK. As a test I blew into the tank through the cap breather which has a small tip over valve in there. When the tank pressure was positive, pressure was trying to escape from wherever it could. In this case with no fuel in the system the air was coming out of the AB's on the nozzles. Thinking about it if positive pressure builds in the tank the idle check will not be able to open either.
Can't understand how positive pressure would come about but hey, will sort the breather first and see.
I haven't had time to run the motor up without the cap installed yet but to be honest our trip is paid for so going to do the mods here at home then test in the pits and track
Looking at your pic the breather appears to just loop out of the tank and point down to the ground, is that correct?

Draw 3D, more than a weep. Fuel runs out for approx 4-5 seconds on two to three nozzles and you can here pressure escaping whilst the fuel is running out.

Thanks guys

Thanks for the advise Dreracecar.
I plan to pull the blue blanking plug out of the top of the tank and run an AN8 hose line from there to the rear of the car. Could you please advise the best way to do this. ie loops, height out of tank.
My plan was to come up from the tank then down to the lower chassis rail using s/steel hose, then connect to ali pipeline following the lower rail up to the rear of the car and out. The reason being I only have a some amount of AN8 s/steel hose.
Can you advise what I should do/use to prevent fuel entering the line and how should I cap the open end at the rear.

Your advise would be much appreciated as I am away to our first meeting with the car this weekend and only have a short time to modify the set up.
I live on the Isle of Man so we're on the first ferry over to the UK mainland Friday morning.

Hopefully the breather setup is where the problem lies however if not there will be plenty of racers who I am sure will lend a hand at the track

Yeah shutting down by pulling the fuel shut off. I have ordered a tip over valve and fittings to sort venting issue you pointed out.

Only leaks when the engine stops after it has shutdown in the pits. There is an air pressure type hissing noise for a short while after the engine stops which corresponds with the fuel expelled from the air bleed holes. Fuel cap is the only vent I am using.
Car only has 2 runs on it as yet.

Hi Guys
I am a complete novice to Enderle fuel injection and have a problem which I hope you can advise me on
After shutting the fuel off the motor shuts down as expected but methanol runs out of the air bleed hole on the injector nozzles. I have cleaned and checked for blockages in the injectors [all clear] and stripped the check valve which again is clean and functioning. It's a 2-3 psi as recommended by Good vibes.
I have not been able to check the leakdown As I am waiting on a tester arriving.
