Supercharger vs mk1a/b

[ioa1980]

Hello all,

Cant seem to find any definitive answer with the search engine.

As the title says really, similar to the MKA vs MKB post.

Apart from the 'obvious' (supercharger and lights ) are there any differences between the supercharger and uk mk1a/b's?

Either in body or mechanical.

Thank you all in advance,

Chris.

A pretty definitive list was built up here:

CLICKY

engine internals are different too. Forged pistons as standard and it runs a different compression ratio. Injectors, starter, altenator, distibutor, spark plugs, coil pack, plug leads, plug gap cover, rocker covers are also different. Some also have aircon, which many UK cars didn't.
Some SC's had an LSD gearbox, others didn't. Driveshafts are different. Inlet manifold is different due to the charger. Brake Booster is different/more efficient. Some SC's had electric folding mirrors, others didn't rear number plate panel is different.

There's probably loads more too...

Not definitive by a long shot

Well, it's the best I could do

Feel free to add to it

E51 gearbox instead of C52 ( has the same internals as the Mk2 Rev1 Tubby 'box )
Different length gearchange cables for the above
Some have US style red side lights on the rear quarter panels ( well, mine has anyway )

One thing to bear in mind though is that many of the differences are not due to it being an SC, just due to being an import - an NA import would have many of the features listed above and on the Mk1 Club thread

its alot quicker!

Thank you all.

Do they need to run on 99ron fuel then?...just like the rev1's...or they suffer?

[System-G]

98+ is what the ECU's are programmed to run on. Although 95 didn't do ours any harm in emergencies although we only put a small amount in until we could get to a Tesco or Shell.

[ioa1980]

Ok, so a 99ron is fine then...just hope Tesco near me doesn't decide to shut up shop!

Is the ECU mappable to run on 95ron? or is it a new chip and remap then?

Just read the link to the other site (above)...the wording in the original post is almost identical to what I was going to write here...scary!

Not if you've stripped the hell out of your mk1b, just ask my mate in his SC when he tried to loose me.

I didn't beat him but it wasn't actually too far apart.

Quite...

Our SC had an over-sized crank pulley fitted and a few other mods. It was rolling roaded with 180bhp @ fly, yet our 120hp stripped out 1a track car was noticeably quicker around any circuit than the SC

It's likely though that we didn't push the SC as hard as it was a cherished car for us whereas the track N/Ail is considered disposable... Also the SC needed the geo needed doing.

As far as I know, the standard setup has a knock sensor so it should retard the ignition if you run on 95ron without the need for any outside interference.

why bother the fuel doesnt cost that mch more and tesco 99 is cheap enough i run my mk1 N/A on Vpower the whole time and there is a big noticable difference in power from bogo standard sainsburys 95 to vpower at 99.

give it what it was designed for and treat the fact that the car CAN run on 95 if necessary as a in emergency only. if you have a supercharger why skimp?

Think the pistons are coated rather than forged in all honesty. Though there seems to be a lack of clarity on this.
