Harrop TVS900 Supercharger KIT!?
Pretty straightforward, I mean these little curve hugging rockets are just too much fun not to modify. Whether it's only $20 or $2,000, what's next for your MINI?
I guess I'll start, this being more of a down the line, smash the piggy bank, eat Ramen noodles, and work 3 jobs type of deal. I want this: Ohhh yes!Harrop TVS900 Supercharger kit! The supercharger is the M45's bigger brother, instead of the previous 3 lobe design the TVS900 is equipped with 4! The kit comes with a cast aluminium throttle body adapter, billet outlet adapter and heater hose adapter! Replacement electric water pump! Straight bolt on upgrade.https://cimg0.ibsrv.net/gimg/www.nor...b5585a9418.jpgWhat a beauty! :eek::eek:
Spoiler
The new TVS900 Supercharger Kit is the result of an exhaustive research and development process aimed at delivering an affordable solution for R53 Mini Cooper S owners who are seeking greater performance or a direct replacement for the factory fitted M45 Supercharger. The TVS900 Supercharger Kit utilises the latest Eaton TVS supercharger technology and provides superior performance when compared to the smaller, 5th generation M45 supercharger factory fitted to the R53 Mini. A significant benefit of TVS technology is the transition to four lobe rotors providing a 160 degree helix, as well as revised inlet and outlet port geometry to achieve greater thermal and volumetric efficiency. Being a larger displacement than the M45 unit, the TVS900 also provides higher performance potential for modified engine packages. Through extensive packaging analysis, the Harrop TVS900 Supercharger is of OE appearance and mounts in the factory M45 supercharger position using the factory 6PK belt path and tensioner. Along with the Harrop manufactured Supercharger housing, the kit comes complete with a cast aluminium throttle body adapter, billet outlet adapter and heater hose adapter, replacement electric water pump and all ancillary items to suit stock and aftermarket top mount intercoolers, ensuring this is a complete bolt-on kit. |
I bet that thing heatsoaks just as bad as the stock blower too. But it's cool the aftermarket is still developing stuff like this for our old R53. I'll add this to my list too.

I cant afford the whole system right now, but I really want that water pump system. I looks clean, it's metal and tucks away well.

It's especially cool that it's totally bolt-on. Comes with everything you need and then some.
|
Just found pricing. It's $4,620. The Sprintex kit is $2,495. That's a pretty steep difference.
|
That is AUS$...you can get it in the US for $3150...much better kit than Sprintex, and the electric water pump setup is worth roughly $500 to replicate.

What's so much better about the TVS kit? Not much in the way of specs for either unit that I can find. |
Harrop is in AUS. Kit is available from a US seller/dealer..leave that to you to find...since it not a vendor here.
The fellows car in the video is on a UK mini site Trackmini...with all his data. Last look he was making around 270HP with E85...but still having problems with his car and getting past 15 PSI of boost. Seems like nothing to do with the S/C since he is running an average size pulley. |
The TVS will actually run cooler than the M45, but as it is in most cases with our cars and replacement S/C's, it all comes down to the tuning and how well the ECU can or will adapt to changes in the way the S/C makes boost.
I can't speak for the TVS, but problems or not, the one thing about the Sprintex option is that it will run with minimal and well known changes to the ECU. The ECU has always been the monkey wrench in the works when it comes to any change in induction on our cars, Sprintex, TVS, Rotrex or Turbo. I do however like the idea of the remotely mounted EWP better than where the Sprintex kit mounts there's, it would probably be much more convenient if there was a failure. |

You hit the nail on the head as well, EACH tuning is key to get the most performance out of many upgrades! Water pump = Major convenience factor indeed. If only the R53's came with an electric water pump standard. I mean damn, didn't think factor in the SC pulley is not only spinning the SC but ALSO a damn water pump. Spinning a properly operating water pump takes a great deal of power that could go to the SC. Seems a bit lazy, and last minute, like the engineer's said "Screw it, ok that'll do" to me. |

Big problem with our cars and the ECU isn't even the performance aspect of the tuning, it's the everyday, the way Siemens adaptations overwrite changes in the closed loop maps is what makes tuning our cars so difficult. I'm waiting to see how these do, I love an S/C car, and the more options the better. |
Are there any spec's on how much boost/power it makes over the stock blower?

Can't you pretty much do the same thing with a 17% pulley for under $100? |

The video showed it making a little over 16psi boost and 188hp at the wheels.......doesn't sound like much of an improvement for $3,000+ price tag.

For $3000......I hope it's capable of making a stock 190-ish HP MINI S into at least a 250+HP machine. That's a lot of money for something with no good performance data on it.
Couldn't you accomplish the same thing for less money with a BVH, pulley, cam, and tune? |

The price of some BVH's are $2000-2500 plus your core.. Then you'll need a tune of course, and why put the stock cam back in there so there's another $400 or so.. bigger injectors, might as well add a header, now your into the $4000 plus range assuming you do all the labor.. but with a good tune you should be in the 250-275 HP range on stock SC...

Honestly it's not $3k for the TVS kit, it's $3k for the kit if you don't need an S/C, or if just want to use it as a power adder, but if you already need an S/C and think you may try and make big power down the road, then it's only whatever it costs over re-doing an M45.

RMW sells it in the us, and they also have a front mount setup if you want to make more power
I believe he said a 20 hp gain on a car that was built up running an M45 and staying top mount, and quite a bit more gain if going for the front mount I've not seen his price for the front mount, or if it needs a vipec |
Quite a few of us already have the bigger head, cam, injectors, headers, exhaust and tuning capability from Bytetronic. I wonder if this would be a better alternative than the Sprintex?
|
Theoretically it has the potential to be pretty good, but you'd still have to go in with the mindset that the kit and S/C is still relatively new for the Mini, and with new items there are bound to be growing pains and unexpected issues.
Honestly though, for guys like us that aren't afraid to be guinea pigs, it probably wouldn't be any worse than any other "let's try something that may not be ready for mass consumption yet" project. |

Yes, it's an Eaton product, I think it's what GM was using on the S/C Cobalts and such, but not sure if it was the 900 model. Same as the Sprintex and the Rotrex, if you look back far enough, your bound to find the R&D that RMW did on it also, it usually does take at least a few years for the new products to be worked out for mass consumption. |
