Finally run a half reasonable time

12.1 @ 111mph

but i have a question... last time with 200rwkw i ran a 12.90 with 200rwkw or there abouts.

now im up around the 300rwkw.

My time has gone almost a second up, yet my MPH hasnt changed one skeric really. Any ideas why that is?

I made a nice 1.90ft, same as my old 12.9 run was.

So they were pretty similar, jsut the times changed :headspin:

At Heathcote i was running 12.7@111 and i have around the 235rwkw mark. What was your half track speed? Should be around 87mph. Something sounds a miss even with a 1.9 60'. Are you sure you werent shutting down just before the line, Ive done that before.

What mph was your 12.9?

12.1@111mph you must be getting of the line pretty quick!, i only ran 12.4@112mph when i went - and i have 4wd launch!

oops, it was 109mph, and id run 110/111 just for times of 13.00/13.10 etc

my 660ft times was 9.3/80.7 mph... i wasnt backing off thats for sure.

I kept my foot in right past the little white checkers :rofl:

i went easy on the launch as the cars just burns the tyres if i try a decent one

my 660ft times was  9.3/80.7 mph... i wasnt backing off thats for sure.

There is something wrong with that 660' time, your at least 1.0 off the pace and 8mph. Check it with your other runs at the 660' mark.

correction, stoopid a$$ me looknig at the wrong sheet

660ft was 8.00

mph/660 was 94.8=68

It has way more than it did wheni ran a 12.9, i seriosuly doubt there was another second in there back in its old form. I've changed nothing traction wise at all.

If anything the tyres are a bit older and crappier now than they were a year ago (12.9 @109mph/200rwkw)

I know the problem. :P

Well m yguess anyway is that the clutch was starting to struggle in the top gears, and what you though may have been wheelspin into 2nd nd maybe into 3rd was actually the clutch starting to give up...well perhaps a combination of both.

That night at Clader where you chopped me my clutch was getting worse with every run, by the end of th enight my mph had dropped 3-4mph when only running approx 200rwkws.

Anyway food for thought:)

with the power you claim your trap speed is way down might be an idea to run it up on a dyno just to double check maybe you have a problem ?. Your abit slow to the 660ft mark and you mph is down thing is your 60ft times aren't bad at all .

For whats it's worth I know my car is abit of a differen't kettle of fish but I have one of the slips here for a [email protected] and on that run went

660ft 7.837@91mph with a 1.8 60ft .

Also don't be fooled into thinking peak power dyno read outs are everything can you tell us abit more about the car and mods .

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
