Cool facts there, worth a read!

Cheers for that!

 

Picture 10 is my old car :O

 

 

Some good facts there i didnt know the sierra had the same drag eficent as a F40.

 

and ECU

 

that was very cool

 

You beat me to it

 

Actually, supercars like the F40 have a rather bad drag coefficient as they're supposed to create downforce.

 

you had a 1.3 pinto running an SU carb? haha

 

Ever get the feeling of De Ja Vu

 

Another bit of coverage for Rod :

8. Rod Tarry’s crazy Sapphire Cosworth has been recorded at an almost unbelievable 206mph and packs an over 900+bhp, making it the fastest and most powerful road-legal Sierra in the world. A record it’s held for a long time!


Surely it should say "MAD" not "Crazy" though

 

Yeh ive read somewhere about that. Is there a bit different inside to run more injectors.

Ive also wanted to know about the Sierra RS500. With it having 8 injectors could/did they all run off the standard ecu and is the ecu which is the same as the Fiat F40.

 

Shame sierras didnt create good downforce cause at top speeds the front end of the sierra start to get light lol.

 

Its still planted at 210mph, how fast do you want to go Glenn .

Did these facts appear in Fast Car mag or just on the website im still looking for mags my car has appeared in.

 

The F40 had 2 ECUs - one for each cylinder bank

As said they run 2 ECU's, each managing one bank of cylinders, the same as the Maserati (430) Bi-turbo etc.

With the RS500 I seem to remember something about Bosch being involved? So maybe a different ECU, or something in addition added to the standard ECU? Remember as well the road cars were different from the race cars, as in road trim they were never connected!

Just on the site Rod. They have a dedicated 'web guy' who posts this kinda stuff up!

 

Thanks Dan .

 

Its a good website is that.Thats where i read about the cars sharing the same ecu.

 

Yeh i knew the injectors were disconnected from new.I just wondered if when people bought them could they of plugged them in and would they of worked.

 

Mines faster than yours Rodney...

 

If they did, it was only mapped for 4 from the factory, so wouldnt have run very well, lol

 

Don't think so tbh, they were not technically wired in either as the plug terminates by the battery.

I have always wondered myself in the past, as I say I am sure I read Bosch was involved somewhere, as I am sure the standard ECU is physically incapable of running 8 injectors, unless you do a hard/soft modification, it's also quite involved as I understand the extra 4 injectors only come into operation when needed.

Thanls for the info lads.Its just one of those things ive always wondered about.

 

wired the other 4 injectors in to what exactly? an injector needs a power transistor to send the current to it to open it on time and there aren't another 4 in the ecu. so where you think you're going to plug them i don't know
