Harrop MINI R53 Cooper S | TVS900 Supercharger Kit Technical Review

Leaders in Eaton TVS Supercharger technology across a wide range of high performance applications, our TVS MINI kit for the R53 Cooper S is the ideal modern boost upgrade to the discontinued Eaton M45 factory fit supercharger.

Lovely, only problem is it costs 3 times the amount I paid for the whole car

[flemmingfrandsen]

I'm a bit surprised in the comparison on the Mini Club racecar. When you compare a "before car" on unleaded petrol to a "after car" that has been converted to E85 how can you tell the increase in power that your "normal" Mini owner is interested in?

[mathieuh]

Excellent kit, would definitely buy if the price was not 4600$ (according to TVS's site)

[warwickdean]

So using the biggest pulley it's creating as much boost pressure as an Eaton with -15% but without running out of efficiency up top? B-)

[fabiovitagliano]

You can easily get 220 bhp with a pulley, ported head, intercooler and 4-2-1 manifold

[fastsmogr]

The track car was running corn for baseline? That’s a huge jump and the numbers seem low even on 91.

[timorgano]

Do you still get delicious delicious supercharger noises? I noticed you do with the BMW E90 kit, but I don't see that often with a TVS supercharger elsewhere

[VON]

Awesome!. I wish that my mini would suit this set up

[sethmorton]

Those stock power levels seem low. My R53 made 210whp with just a 17% pulley, intake, and tune. It was 175whp stock. I was told by the tuner, who has been tuning MINIs for a decade, that he has never dynoed an R53 under the stock crank horsepower rating. How could there be so much discrepancy in measured power?

[djserafin]

How do you do oil maintenance ? Same as the m45?

[JussiKoukku]

Why does everyone think the price on their site is listed in USD? :D

[ioloutbound]

so your telling me, 5000 dollars with shipping and handling for 30 HP? BOO
were better off adding a wet nitrous kit and E85.

[stephenswytak]

It appears M45 has more torque up till 6000 rpm. Unless you are racing, stock M45 performs better in real life. E85 testing is irrelevant for street cars.

[leandromachado]

Will this fit 2006 jcw GP? What keind modification I have to do ?

[_alltheseprettylights_]

The first mini ones were not the r53. It was the r50s.

[uncomn]

What does all that extra horsepower do to the 0-60mph time? Not that much I've read.

[minimanadam]

Alot of that hp was from the tune alone, should did it on standard ecu tune
Then on next car they added e85 tune too then so these numbers are very inaccurate

[darringoodbrand]

how much would a supper charger kit like this cost ???

[minimanadam]

Too its ridiculously expensive. Hard to buy a part that cost as much as my car BUT it is the last mod I have to do besides better pistons . I just ported my m45 and put on a bvh and race cam so I sure could use a tvs

[WPTUNED]

you also need to tell these vehicle owners to stop wasting time with the top mounted intercooler. Front mount conversion is a must!
