Update, 4v tune with tounges - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Well a few little problems have been sorted out, the main thing was a change to a resistor type spark plug, the car is now making power to 7200rpm, the tounges combined with the new spark plugs created an extra 2 inches of vacum, the 850dp was getting sucked into the mainifold, a 930 proved too small as did the 1050dp, we will be changing the inserts on the 1050 to make it 1080, hopefully that's big enough, Hallam Performance asked me come in this afternoon and test drive it in a semi tuned state, they said the tractive effort "N" figure has reached 7200, so i went for a couple of laps round the block to warm the old girl up, then i stood on it at 3000rpm in 1st, took it 7200 changed to 2nd, took it to 7200 then 3rd 7200, when i hit fourth BANG, there goes my new inputshaft, snapped in two !, so on the bright side it's feeling very strong, but now i have to find an aftermarket input shaft as this new standard one didn't last one day :(

Ouch thats got to hurt! but not too many cars can claim to break shafts so easily!

got an email from my mate with the blown coupe in the us and he broke his big block toploader the other day same thing!

I have enough trouble with a 351 let alone a blown coupe lol.
But who needs forced induction when you're car lights up the tyres in top gear while strapped to a dyno :)

Man you've had your fair share of heartache. You know good things are going to come to those who wait. I recon both wheels, 2 foot up...

Ever thought of a C4 with 5000 stall. I can just imagine it now.
Keep it up Nick.

Funny you mention that, the words C4 and conversion slipped out while at the shop today, but what can i do, i like the manual shifting.

Bummer Nick, that sucks. Cams first now input shafts

Oh well think of the cash you are saving in fuel......

.....Yes I guess you're having trouble finding positives also

Stick with it mate

Always getting shafted one way or another.

I saw it today. Can't get a cleaner break than that. The breaks mirror finish!

OUCH you have to hate it when that happens.

i have twisted the top loader imput shaft about half a spline without it breaking. that time i had the fronts off the deck about 6 inchs . makes a good trothy if nothing else. i did both axels at the same time . but as you say its still nice to change gears.

you must be making some serious power

crochunter · 07-22-2005, 04:02

Dont need power to twist shafts. Just try dumping clutch at 700 rpm will do it everytime.
