Tight Arse Turbo....new PB

There is a T&T on Wednesday the 27 June. At this stage Dave Butler and myself will be attending.
Would be a good opportunity to do some testing ready for Warwick or a tune for the dyno day.

If your interested in participating or just having a look come on out. Now the Winternats are finished I'm hoping it might be a bit quiet.

Im always there. i think the only couple of nights i've missed is when the TAT has run

I have been told that the track should be well prepared due to some big name racers testing😎

Dude,

you buggy would be a serious weapon on the street.

how much fun do you have hosing cars?

Love it!

buggar...I was hoping that with the Winternationals over it would be a bit quiet

looks like the weather might turn to shit...fingers crossed.

Was going to come out with my Corolla for it's last run before I sell it but unfortunately I sold it today so I won't be going now....

it will be veeeery chilly, so rug up if you're coming

Rareing to go....with a jumper!

Any diagnosis yet Stanley ?

not yet...but I can tell you what it isn't.

Not the SU jet
Not the float bowl needle and seat
Not the plunger spring
Not the fuel pressure
Not the timing
Not the valve adjustment
Not a dirty carb (I don't think)

At the moment it has to be a carb issue but I have NFI what. Will investigate the carb further.

aaahhhhh carbies....................................

I remember the days......and nights wastes looking for problems. where to start?

don't let it get the better of you, it might be something simple often over looked. I use to walk away before smashing things, and sometimes the most stupid thing that comes out of the mouth that knows nothing about cars is what helps.

chin up !!!!
it happens to all of us!

Just a bit more to add following my dismal showing at this T&T. Was all set to run hard with the new boost controller fitted and richer SU jet but it all turned to shite even before I arrived.

Noticed when I gassed it after coming out of a servo that it started back firing. Thought as the weather was cooling off it might have been a bit cold or even needed a bit of adjustment on the mixture. Drove to the track and it all went down hill from there.

Basically it was running so rich that it was backfiring and shooting a flame (which looked neat) out the exhaust. Decided not to run as I needed to drive it home and couldn’t afford to break it.

On the way home it was down on power and by the time I got home it was like it was only running on 2 cyls. Assumed it was a fuel issue so pent the next week moving the fuel press reg to get the pressure down and trying every combination of bits I had to stop it from running rich.

Ended up taking off the Sigma ignition and fitting the 009 to see if that would help. Then it wouldn’t even run and now won’t start. Noticed a quantity of fuel siting in the carb and thought it was still getting too much fuel. Must have pulled the carb apart 4 times looking for problems.

It was then I realised the fuel was pooling because the turbo wasn’t spinning because the engine wouldn’t fire due to a lack of spark. So now I’m chasing an ignition problem but have replaced the coil, dissy, rotor cap and button, high tension lead. Still no spark at the plugs although I have some spark at the points.

Hopefully this weekend I can track it down. Any suggestions greatly appreciated. I have had to hide my axe.

Frustrating after having no probs until now.

long shot but check your regulator (under rear seat) are the terminals rooted? I had an issue with my kadron/009/1641 that seemed to be running on three or so cylinders. I hooked up my batter charger and fired her up again and I noticed that it seemed better. I cleaned up all the terminals and replaced the ends and that seems to have got me sorted. As I said long shot but easy to check, if you return the car to the pre-shitting itself configuration does it behave?

Cheers Stephen

What plugs are you running???

Sounds like a low voltage problem. Fouled plugs will cause the same problem.

What voltage have you got a the coil?

Plugs are what is recomended for a volksy but were set to sigma gap.
Have 12.5volts in to the coil and remains while cranking. 5 volts coming out.

put new stock plugs in and stock dissy in for a back to back one at a time.
A waste of time but this way you eliminate them as a problem. Sometimes it's the simplest thing that gets over looked and you waste a lot more time. I would also check manifold gaskets.

hmmm, tried some fresh fuel dude?

have you changed the condensor??

Been on a course this week so haven't had time to venture to the shed. Will spend tomorrow trying to find the source....thanks everyone

here's some more info 'cause it's got me beat. I know the problem but can't find the cause.

Whatever it is, is destroying the capacitor. Have been through two which is part of the reason why I've been chasing my tail.
When I hit the starter I have a spark (via timing light) at my HT lead but not at the plug leads. (i've changed caps, rotors and the HT lead. This problem first surfaced after I fitted the sigma dissy etc so it is something common with that and the 009 currently fitted.
Also when I hit the starter it cranks but won't try to fire until you turn the starter off. There is a short somewher but I don't know where.

are you sure your coil is earthed properly? use a multimeter with continuity when the car is running what volts is the alt/generator putting out at idle?

coil bracket is bolted to the rear fire wall.

thanks

My Guess would be a problem with the ignition switch

The coil power wire is the original one??
Sometimes if the coil power is taken from the ign on fuse, not the starter switch, it cuts power while cranking over, and then sparks once you return to the ON position...
if that makes any sense! sounds confusing.

Are you running compufire in it?? Maybe it says somewhere here I havent read the entire thread sorry..

Thanks guys...going to spend a couple of hours this afternoon doing some trouble shooting. I'll check your suggestions.

Cheers

Well it seems to be fixed thanks to Dangerous Dave Butler. Dave came up y'day and spent 4 hours helping me troubleshoot (I actually think it was the other way round).

We changed every part of the ignition system and isolated all the wiring until the car was basically an engine stand with an external power supply. But it still wouldn't start. Got to the stage where I heard Dave muttering something about aliens.

Anyhoo to cut a long story short we (Dave) worked out the only thing we hadn't changed were the plugs. We pulled them out and they were sooted up. We cleaned them up and believe it or not it started first go although still backfired which was the original problem at the drags.

I've sinced replaced the wire from the batt to the regulator and fitted an additional earth strap, cleaned up some wiring and fitted new plugs and it runs well and doesn't seem to backfire now.

The plugs have done less than 200 miles so who would have thought.

A special thanks to Dave for taking time out to offer his invaluable assistance. It's now safe to bring the axe back out.

So does this mean we'll see the TAT at DYNOMANIA??

I'll let you know today after I take it for a drive. Also need to fix a potential fire hazard.

Well because of the drought the last 4 T&T's at Willowbank have been cancelled due to being washed out??. So tonight was the last chance this year. All was going good until my trusty tilt tray driver had to go Christmas shopping instead of racing.
So I drove it out to the track and run a PB of 15.3 @ 89.5mph with about 11 lbs of boost.
I had 2 stabs at 3rd so I reckon I would have cracked 90mph.
Next run lost all boost for some reason. Checked all the hoses, everything seemed ok, checked the turbo at home to make sure it was still turning (not seized) and it was all ok. Early diognosis is dodgy boost control. Stay tuned to find out.

Now i'm going to run in the Willowbank street series and have run fast enough to run "hot street". I predict 14's next year with some more tweaking and driver training.

Well done. I see they put you up against a nice slow street car as well 😂

Three of my runs were next to 10sec street cars. They make you concentrate more.
