SLEEPERS! Anyone have a street sleeper here?

Sold a very tidy one with 50k on for £500 in November, just needed a couple of little jobs but would have made an ideal base as it was so fundamentally solid.

But, would need some space with nothing to hit to get a feel for a 300 plus bhp MGF, could be great, could be utterly terrifying, likely a bit of both.

When they go, they go!
I do know someone who managed to stack a MK2.5 MX5 through a hedge (he gave racing driver excuses for days!) and Mrs D went backwards at 80mph in hers (wet track day, Nexen tyres, changed gear halfway round a fast corner). But you have to be driving like a knob to really come to grief in an MX5. They are very good at warning you and then giving you some leeway. There is/was even a drift school that used them.

The MG engineers however appeared to have gone "right, it can pull loads of g's. No-one will ever try to use ALL of the grip, so job done."

I love my little TF but it's a very different car to the MX5!

Recently had a Rocketeer conversion (3.0 AJ30 V6) completed on my MX5, not crazy HP, but just shy of 300bhp in what looks like a std 25 year old mk2 mx5 weighing appox 1000kg can be unexpected

Handles too as keeps the same weight distribution and had a little work done on the suspension

Trikster said:

Do like these but it totally changes the balance of the car

See above.

IIRC there's little change to the weight distribution. The v6 is all aluminium and the old MX5 engine is an iron block straight 4.

Edit, not sure if quoting is messed up. Balance of car comment seems to be referring to a V8 conversion.

The Rocketeer V6 setup is 40kg lighter than original

Had the guys at Rocketeer do it, must post a build thread at some point....

Please do!
I'm toying with the idea on my ratty na

What he said ^^^^

On the cusp of going from conversion to full resto myself and soaking up anything on the matter

Inserting head into lion's mouth here. Because wheels and maybe some other reasons.

But

600hp Skoda Estate has to score some sleeper points because even if you think it might be quick because wheels, 600hp is going to surprise anyone.

O/T anyone help Me understand the giddiness of Methanol Injection ?
In my world of ships, methanol from a calorific aspect versus diesel is poor -circa a third pro rata. Is it about the squirtability or something ?? Makes no sense to me
(Or are all methanols not equal?)

That Skoda isn't diesel, but I think it also cools the charge as it's burning so you can run more boost and fuel.

Thanks ! A different application to how I imagined.
So it’s about emperors / thermodynamics versus ‘fuelling’ per se

Happy to dance with the lions - excepting the aftermarket wheels, its a Q-car.

And since the different between Q-cars and Sleepers is irrelevant due to the Atlantic Ocean separating the etymology, its a sleeper.

Oh jeez there's two of them

Change the wheels to something more stock looking that hide the brakes and it's there.

As far as I know, never had a reason to use it. You can use it on a tuned diesel to clean up the smoke and make more power too as it does have a calorific value and doesn't generate as much heat as normal hydrocarbon fuels. I think a lot of the time it's combined with water, a WMI setup and the water meth does an effective job of both cooling the combustion (EGTs kill turbos etc) and adding a bit more power

The first one definitely isn’t a sleeper. The second one is perfect

Haha st sorry

Its clever stuff, it can be obviously as par to the fuel, like the E85 they have in America which can produce huge amount more power if the car is mapped to use it, they put a "Flex Fuel Sensor" in and it analyses the Meth content of the fuel and can adjust the map it uses accordingly, saw one with a Supra tuned to use it and it was another 80 bhp.

It can be injected into the air intake and either used mainly for intake charge cooling or as a combination of cooling and to add additional power, depends on the application and tuning, both methods add power as can run higher boost, ignition advance and add more fuel but the latter will add more, think sometimes its sort of more like water injection. It keeps cylinder temps down and resists pre ignition (pinking) which is typically which is what can kill a turbocharged engine in short order with holy pistons and melty mess.

Skoda estate looks fast, would expect it to be fast.

600bhp fast?

ajprice said:

It looks like it will probably be fast to me as has big wheels and big green brakes showing, could be 600bhp fast as wheels and brakes are upgraded but who knows/cares.

Would be more suprising if it looked boggo.

Maybe the fact it looks like a fast model with the wheels you expect it to be vrs kind of pace at the very least which isnt slow.

Sorry for having an opinion, carry on.

Exactly. To the casual observer and the uninitiated it looks like a pretty ordinary Skoda estate with slightly bigger than standard alloys and painted calipers. Even if I thought vRS, I wouldn’t expect 600 bhp.

Does this count as a sleeper?

I bought this last week, it's a Saab 9-3 (obviously) but has the 2.8 V6 turbo and four wheel drive. Bit of an odd spec as it's not a Turbo X but is 99% the same but from the outside there is no mention of the engine or drivetrain just Aero on the bootlid. Wheels and grills were a styling pack but again an option.

Not mega power with 280bhp but I think it's very subtle and 295lbs-ft gives it bit of punch like diesel but with more revs.



A basic remap would see 320bhp and nearer 350lbs-ft.

MightyBadger said:

Eeeer righto.

Will buy a c63, take off all the badges, put steelies on it, spoilers off and stick a c200d badge on it, will look like a diesel, sleeper yeah

Seems like cheating and not much like the traditional way of building a sleeper’ from a slow car.....

But I suppose the outcome is the same, I concede.

Carry on. I’m off to get some 1.8 badges and steelies for my daily.

Edited by MightyBadger on Sunday 21st January 08:32

Correct, that's exactly what you would have! A car that looks like nothing and goes like a storm! In fact that would make a far better sleeper than a C200 with a C63 engine because the whole car is engineered properly to take the power.

[glazbagun]

I'd consider it more of a Q-Car than a Sleeper (not to reignite that debate) but yeah fast Saabs are only going to be more surprising as they fall from popular memory.
