Supercharged?

[Negativvv]

Ive suddenly found the urge to partake in some Forced Induction ownership

Basically i fancy a Super Charged mk1 or possibly a mk 1.5 if i can work out the logistics of building one.

Was a SC i was mildly interested in on the 'bay but the auction ended with only me and it didnt hit the reserve. It looked like a possible shed tho (no offensive if its sum1s car on here!!), it had a cooling leak somewhere and a pulley for more power. Also found from the owner it was imported here very early in its life and was an early sc too (89 and 87 respectively)

I probably wont do a mk1.5 as my current mk1a isnt the best shell ive seen altho its not falling apart either.

The questions i have is how much difference is there between an sc and an n/a? A friend thinks i shouldnt waste my time as the bhp gain is only modest but the torque gain is pretty big! While i dont find the n/a slow as such, it isnt exactly fast either!

Oh and how different does the sc sound? Its important that i can hear the sc whine a bit...

Thanks!

My personal opinion is that stock for stock its not worth the extra money to get an SC.

You could spend some money on your engine, stript he car down a bit and you'll have one biting at the heels of a standard SC with no problem.

However, once you put a big pulley on an SC it makes the difference massive.

There are limits to the power output of the SC due to the engine design.

If you going to be happy with around 180 bhp then go SC - if you want more then you may need to look at a 1.5 engine conversion.

NA and SC are in my opinion similar in performance when standard. I was left disappointed after test driving my first SC (145BHP). It wasn't much quicker than an NA because of the extra weight. It felt quicker at motorway speeds, but not fast enough for me.

Do the pulley and ABV mod and the SC is a completly different animal... the SC unit makes a great noise, it gets louder and louder (and goes faster and faster) the longer you keep your foot in. With this mod you go up to approx 175BHP.

My opinion on the 1.5 has been well documented, they are fantastic, the power is phenomenal and again is a completly different animal to a pulley modded SC.

Does the oversized pulley reduce the engines reliability?

Altho i think ive read theres ppl here whove had it on their car and run it for years and years!

Standard NA produces about 122bhp at 6600 and 105lbft at 500 when new, whereas the SC produced 145bhp at 6400, 137lbft at 4400 .

However bear in mind that the SC figures are for a car equipped with a cat - unless it's jusy got off the boat an SC in the UK will have maybe 5bhp more due to no cat in the exhaust.

The car on ebay had a modified pulley - these give more boost hence more power. Std boost was 8psi, but with a 178mm Fensport pulley ( and the ABV mod to stop the ECU limiting the boost ) my '87 car hits 12.5psi and has been rolling roaded at 196bhp at 6625rpm and 182lbft at 4426 rpm.

The car is much faster than an NA, and sounds wonderful when the SC is doing its stuff - you can hear mine in this clip http://bookatrack.com/-PFmartg332327114 ... o/x-ms-wmv

It did for me!! My pulley lasted a grand total of 3 days But that was because it was fitted loose, wobbled off and damaged the crank.

As you say, other MK1SC owners have run this for many thousands of miles with no problems... other than excessive fuel consumption!

Pulley doesn't tend to affect reliability.
Never heard of it being an issue.

Had my big pulley on for about 4 years now. Only reliability issue is with the smaller idler pulley provided by Fensport, which tends to fail after a couple of years. However at around £25 for a new pulley it's cheap enough to be regarded as a consumable.

clicky me

^^ this one

drop him a line, he wants £1500 for it and it hasnt sold yet

[Charged]

^ very cheap in my opinion.. i cant believe SCs are going for under £2k, even in a slightly shabby condition. Surely the prices are set to go up soon!!

Thats a good case of "the price is right" You know him personally?


Now all i gotta do is get this mk1 working and sold!!

Or keep both and strip what is good off yours to make the SC better.

Totally

I think that one has ICE but mines frankly better as ive just blown £200 on a decent unit/front speakers. Ive actually done loads of little things to my red mk1a. It isnt quite as faded in my sig anymore either

Its actually quite a shame if i got rid of it as its the first car ive done all my own work on!!

Well, if its an AE101 conversion with the I/C removed and WI fitted...there is a LOT of difference.....

Compared with my old N/A...no contest!

I have the standard pulley....10psi (measured both electronically and mechanically)...stock ABV, and it suits me fine...

I have bought the oversize pulley, but cannot be ar$ed to fit it......!

TBH, the SC12 is a crap supercharger: almost any modern Eaton p1$$e$ all over it......if you fit the oversize kit, it merely brings the unusable inefficiency band down the rev range...unless you start spending on uprated intercooling, etc.....

But whatever you try to cool the charge down, its p1$$ing in the wind, at the end of the day....

Solution..?

Fit a more efficient S/C......! (M62 / M90 / or a twin-screw: Whipple, IHI, Sprintex, etc)

Then you'll be in the 200hp bracket, but with shedloads of torque low down........

[010on1986]

Still have the big pulley to look forward too, such is the art of delaying gratification.....If the sc had the na weight it would be perfect. Everytime I drive my NA i wish it had the sc's power/torque. Everytime I drive my sc I wish it has the NA's weight. sounds like a v6 could be the way...

I dont know the white one, but I enquired to what the reserve was.

I know the owner of the blue one

I have been conversing with the owner of the blue one on here

Currently in negotiations with the white ones owner!

Oh and another strong reason why i want a sc is that i desire AC

Ive lived with it for ages and much prefer to add a few kg onto the car and be able to chill out in Summer/demist my windows fast in Winter!

I must admit to hankering after SC ownership as well after having had my first drive of one this time last year. (one with a big pulley and a fantastic whine)
I had a long chat with HT earlier this week about his - sounds like a good 'un to me, and I sooo would if I could.
Completely gutted - when I have the money I can't find one I want. Then I go and spend on the current Mk1 and other odd bits and pieces and suddenly more than one comes up that I'd love to have...

I'd go SC before 1.5 if it was me, to go up in power progressively and get used to it.
Also, if I could I'd keep the NA and SC as they both seem like different cars - the way they give the power is rather different (but again, I drove the SC on track so it could just have been how I was driving... ). But then insurance and tax may be a problem there...

[Negativvv]

Good to see im normal (atleast in this company) when i say i hanker after the sc whine

Having something with forced induction is on the list of "thing to do before i die" so its looking more and more likely
Peaky n/a is starting to bore me too (blasphemy!!) and mk1a isnt the first of that engine type ive owned, sometimes all i want to do is change up early and ride the torque
