They won't need to make any brackets, so it'll be done within a week I reckon.

How much power can you get from a reasonably stock Toyota 3S-GTE engine? I've known MR2's claim 600bhp but as it's 4x4 it might need a bit less power and a bit more grunt.

What do people reckon? Will they be doing a stock-ish 250bhp, or will they be caining it for a 500bhp monster?

^^^Somewhere inbetween.

Hope they live long enough to compete in it.

Hmmm, frontal area is quite small, as is intercooler space, unless they're going to do air to water chargecooling. Heat management is going to be tough if hitting high numbers.

The 4wd system gearbox and diffs are another bottleneck, but the car will be lighter than a 1400kg Celica so they can push the envelope a bit there.

I'm guessing a light tune of 275bhp, torque 400NM. Should hit 60mph around 4 secs, top out at way more than would be comfortable in any spec mini.

Once the suspension is dialled in it'll be mental, due to the short wide wheelbase.

Looks small, but it's a notoriously bad shape and those big wheels and arches won't make it any better.

Mini tuning guru Richard Longman reckoned it didn't matter how much power you put under it, the drag the shape created meant you could never get more than 125 mph out of one and all of his writings on the subject said fitting wide wheels (the first thing all the boy racers did) did more harm than good.

Having said that, I don't think even he spent 5 years + getting a 275 odd BHP motor and AWD into that bodyshell, so he might be proved wrong,

I'll be interested to see how they finally gear it, for top end or acceleration.

^was only looking at how much heat they can shed, not drag.
125mph is too much in a Mini anyhow!

I don't think gearing will be altered for fuel economy reasons, the payoff is probably not worth it.

Once it's working, it will be interesting to see how good the cooling system is.

I spend a lot of time working with Triumph Stags and there's a lucrative business in ally, large core rads, matched to electric fans; except they don't work as well as a good condition standard fan and rad.

Apparently if maintained properly the cooling system is fine. It's the iron block and ally heads that generate quite a lot of corrosion that blocks the OEM rad.

Original gearing is 152mph max, with stock 239bhp the mini will achieve almost that according to calculations online.

With 275bhp and gearing, 158mph max.
Frightening either way.

Without wishing to go too far OT, the original problem was a combination of poor maintenance and lazy manufacturing.

Sand cast heads that weren't cleaned out properly at the assembly stage (I've seen lumps of sand fall out of original heads) that allowed grit to circulate around the engine.

Poor maintenance came down to the regime of the day; nobody was used to aluminium heads, so the general MO was to run water in the Summer, anti freeze in the Winter, which contains the corrosion inhibitors that ally heads need all the year round, hence a corrosion/silt build up.

Plus there's an inherent design fault with the Stag engine, which places the water pump at the same height as the radiator header tank, so if you allow the coolant level to drop, the pump has nothing to circulate.

Run it on decent coolant all the time and check the level once a week, you have one of the most efficient cooling systems of any car on the road.
