...and how did you like it? What kind of gains do you think you got vs. the factory eaton SC? For the money, was is a worthwhile upgrade? Any drivability issues?
Also, what did you pay for the kit? The Harrop website is showing $4,620.
Looks like my option between TVS and Turbo is boiling down to TVS. Too much cost difference and the TVS will get me pretty close to what I want. Does anyone have any experience with the TVS?
I went with the Harrop TVS900 when the Eaton on my 2005 was dying five months ago. It is outstanding!
Admittedly, my 2005 is far from stock, but I am putting-down 285HP@7500RPM, more than 110HP over stock, and I have no complaints. That's with a street cam, BVH and a header. I could easily hit 300 with a different cam, but what I wanted was a "torque monster," and I got it: Peak torque is 229 foot-pounds, and it is broad, with more than 210 foot-pounds from 3000 to 7000RPM. It is smooth and tractable, with instant response when you hit the accelerator.
RMW did the install & tune on mine. (Third cycle of mods & tune over the last decade.) puttn can always give Jan a call to discuss what he would like to do, and budget. I have found him to be innovative, and good to do business with.
.
That $4,620 cited price is actually $4,620AUD. (Harrop is an Australian company.) In today's US dollars, that would be $3,358 according to my converter, plus shipping. Jan quoted me just under $3,500 including shipping, last year. It looks like exchange rates have improved, as it is currently $3,350 on the RMW website, here: http://store-revolutionmini-com.3dca...-kit_p_46.html
FYI: You will also want the RMW tensioner, with its redesigned mounting bracket, because Harrop uses your orignial tensioner, which provides less wrap and less tension than we have on the Eaton, and there are slippage issues at higher RPM.
.
you dont have a before/after dyno vs the eaton do you?
I have an "after" dyno image below, but I don't really have a representative "before". That's because when it was tuned after adding the BVH & header, we discovered fueling problems, requiring fuel pump replacement that happened a month later, and I didn't rerun it. Fuel issues limited HP to 230 max, and that improved (butt dyno) after a new fuel pump & filter.
Here is the dyno results after adding the TVS900 (with my Mini reflected in the screen).
These results are for a combination of what I had 18 months earlier, plus the TVS and a RMW 1.8L shortblock stuffed under the existing BVH. (The original engine had consumed oil @ 750 miles/qt. when new, and over 100,000 miles, and it had gotten worse.)
The loop on the dyno plot looks a bit weird, but happens if the specified dyno acceleration rate is exceeded (I believe Jan specifies 500RPM per second). When that happens the dyno brake automatically forces the engine back below the deviation point, and then continues. At least that's the way it works on the DynaPack.
(This dyno facility on the edge of LA where Jan does his local tunes is pretty amazing: four chassis dynamometer bays running at the same time, both 2WD & AWD. There was a 1000+HP Cadillac CTS being tuned in the bay next to my car.)

It's working fine so far. Installed with the 70mm pulley which is giving about the same HP as the M45 with a 15% reduction pulley. The 65mm pulley is going on after the CotA race weekend May 3,4,5.
The IATs are much better and heat soak appears to be almost a non-issue now. The M45 was being run literally off the Performance Map. The TVS 900 isn't even being pushed yet.

Drivability is a tuning issue. This is in a race car.
Great pictures. Wish I had that type of money. Been watching a group on FB where this guy did a m62 supercharger from a Chevy. Wild stuff and he fights like cats and dogs with the rmw guys calls them lemmings or something. LMBO with the fights. Guy backs up his stuff with pictures and data. He he did a cost thing and $900 to $3330 is real sweet

I've seen that on Facebook, and I applaud his enthusiasm, but there's a reason why DDM abandoned that project. And if I'm not mistaken his final cost for that project was about 2/3 the price of the TVS kit and he's having to run a water/methanol injection kit to keep the intake temps down. Biggest issue with the M62 is the extra heat generated with the extra boost. With the TVS, you won't have to worry about that. The setup I have should produce 19psi with lower intake temps than my old M45 with a 16% pulley making 16psi.
Man I dunno about that price, he had 900 on his chart and claims he did a meth kit for 300 so that is way cheaper than the TVS at 3300. He posted charts that had his temps and they were close to the m45 he had with a 19 pulley. What mods you go on your car to go with that sweet TVS900? The wife know you spent that type of cash on the car?
Want to see some numbers when you have yours going

I would go back and find it but apparently I've been banned from the group for disagreeing with his point of view on the M62, but if look at one of the earlier threads when he first posted it, the full cost was closer to $2000-$2500. His cost was $900 because he got a good deal on the original DDM Works kit that someone had sitting in the garage collecting dust.
As far as mods, I have a RMW BVH, Dominator cam, Street header, Link ECU, 1000cc injectors, E85 flex fuel system, and the TVS with the RMW redesigned tensioner.
LMBO you must be one them lemming things or a parrot. Up the pulley a little and you got less heat. Man the costs are no where near 2500 more like 1200 if you aint afraid of a little grease. I am diggin that guy trying too save me some cash. I got some buddies that can do aluminum welding for some brewskis and I could do little porting on a used head and get me a junkyard chevy m62. For 500 cash betcha I could have some fun. The pollack guy he talks about is making a m62 kit for like 1500 and man he even has a amg twinscrew on a r53. He is calling the amg mini the beast.

Well that's cool if that's the route you want to take. While you're at it, check out his brake setup as well.
chill out man. my parents didnt raise no dummy and I aint spending big bucks for some fancy aussie air pump when some good ole chevy blower works. You want to spend your cash like that have it.
and I saw the brakes he did and they look pretty good. guy said he just got back from the dragon and they worked fine. A man's got to know his limitations and I dont see the need to spend big money on race stuff when you are driving the car on the street.

Going for the Harrop isn't being a dummy (as if there's need for insults), it's taking an outdated design with heat and PTO issues and getting something more efficient, while lowering heat and getting rid of that dumb PTO. Is it pricey? Sure, but it's clearly well designed and proper R&D isn't cheap... In a couple years, the price will probably go down. It's cool and all to fit a Cobalt blower on there, but then you have to fit everything, buy an electric water pump anyway and all that jazz. To me, that sounds like a lot of work to install a blower that is as old as the Saturn Ion Redline...

Charlie, at this point I know it's you. The only history you have is on this post. And the language you use is a direct reflection of the posts you have on Facebook.
man you guys need to chill out better LMBO cuz charlie wants to know who i am
Either way, he picked and outdated blower to build his project on. He would have been better served going with a used TVS unit if he really wanted to save money and still get better performance. There are plenty of used/rebuilt TVS units for sale on eBay that he could have used for his project. I ran across a rebuilt TVS1320 on eBay a couple weeks ago for $350.
Narvarr...did you get yours installed and running?
Yes, it's finished. We had some pretty bad weather here in the Dallas area over the weekend so the install was delayed a little. Took it for a short drive today after I received the new tune file and man is it strong! I didn't really push it hard since I have to set up time with Jan to do the final road tune , but where it's at now on the E85 tune is really impressive! It gets up to 18psi in a hurry and I only went up to 6000rpm!
Coolant temps run much cooler with EWP that comes with the kit. More than likely due to the pump not being RPM based. At cruising speed, I normally see engine temps around 198°- 202°F, now they're in the 189°-192° range.
