987 supercharging - Page 2 - Boxster/Cayman - PistonHeads UK

Hello all anyone know of any good companies / websites to look at supercharging a 987 boxster? rough price? thanks

Do you have a gen 1 or gen 2?

I don't know of anyone offering supercharging but MRN do a turbo kit. Their test car made 470bhp. I think it's about 6k for the kit. https://www.mrnracetechnologies.com/product-page/9...

By the time you have fitted that, ironed out the niggles and upgraded the brakes and suspension I would say you would be well in to the territory of buying a much better car and I say that as a Boxster s 987 owner.

It's good power for the money, I bet the results are great on the road. There has to be a question on reliability though, even a standard the 3.4 is a flakey engine.

What cars are you thinking fit the bill? I can't think of many mid engine sports cars that would be better than a 470bhp 987 without spending big money.

Different people's definition of the highlighted could be 2 grand or over 10. Modifying cars is always expensive. Thats why I try to buy them already done.

It depends if you class the 470bhp as better than a smaller number or the overall experience of owning and driving the car. The end result will not be worth any more than a standard car really and a very small buyer audience, it depends on the total conversion cost but you could easily spend £20k getting it right. I would say a v8 R8 would be a better home for not a lot more money….as an example. Don’t get me wrong, it is about the journey too…I have a £26k cossie engine waiting to go in to a car with £5k dampers on it….my experience says that a better car would be better value.

This is the thing Do you want a normal or standard car like anyone can just buy from a garage anywhere in the country or do you enjoy the feeling of having a car which is very unique and that you have had a hand in developing One is a car The other is a project yes but some of us like our pet projects

Perhaps we should offer up this cheeky little example which is for sale right now for (only) 25 grand I'll be honest, I don't really know what the last pic is showing https://www.ebay.co.uk/itm/144455644247

Nice cayman and the normally aspirated v8 would probably suit the car better than a turbo (imo) Looks like it needs some finishing I.e. the breather system and oil catch can not connected up, that will smell oily as it is. Ecu "could do with a dyno session" probably means it needs a bit of sorting out. Not sure how you would make the exhaust quieter with the packaging constraints. It’s amazing to think you can get a v8 under there that was never meant to be there.

I think you're reading too much into the ad. Those pics could have been taken before pieces were finished. So don't assume it needs breathers connecting up just because you can see that in the pics. Escy above wired up the engine for the owner. So he will know more than Us. Apparently the guy had a series of build videos on YouTube but these have been taken down now - which I'm sure most people will see as a negative. I think if you are the sort of person looking for a sensible car or looking for potential problems or for reasons not to buy this car them you don't need to look too hard. But if you are the sort of person who likes interesting cars then you have to admit this car nails that interesting thing.

You don't necessarily need to go to town on supporting modifications although I think a proper diff would be a must on the shopping list. A bog standard Cayman S with this turbo kit would be a great car, probably faster than a V8 R8 and I'd guess (as I've never driven one) also better handling and cheaper to run also providing the engine stays together. Big brakes are nice but it's not essential if it's a road car. The base car is brilliant anyway, adding more power doesn't change that. This turbo kit is a bolt on affair, I think they supply the map for it so there is no getting it right needing to be done, should be a case of drive in, drive out. I think it's an interesting option.

Maybe the owner just did a poor advert, I would have thought a finished pic would be better if they had one? I do get your point, I have a 205 pug 4x4 with cossie engine, it is far from a sensible car…mainly home built.

I have the 987.1, I would 100% agree that the diff would be a good option, mine has around 300hp and can spin up an unladen wheel on a damp road. The torque that comes with a turbo would easily corrupt. My brakes are good but not great although I have not had to replace the discs or pads yet so may be just them. They seem like the brakes on other 911’s I have owned. A map based on the kit would fairly generic I would have though as there will be quite a few other factors based on what else may have been done to the car.

The kit consists of everything, their induction kit, their intake manifold parts, their charge cooler system, their exhaust system. There's nothing really where your spec is going to deviate by much. It's not making that much torque I think they've capped it for reliability. It's similar figures to the GT4RS, same bhp but 50nm more torque (497nm). which will be available lower down the rev range. I think it'll drive really well. My Boxster makes 730nm of torque which is fair amount more, I've got a Quaife and it put's it down really well.

Does the 987.1 come with PSM standard and does it do that voodoo of applying an individual rear brake and is that to try to limit one side spinning like an LSD or is it for something else? I know the newer cars do this and you can't turn it off right? The 981 can cook a rear brake on track right?

Yes, it does that. With a proper diff you'll be able to avoid most of it.

I assume the kit is charge cooled, do they get much heat soak?

I do wonder how much development and testing went into it, the charge cooler cores they use aren't brilliant, I used them on my car and they weren't up to the task. That said, I was running 20+psi, they are probably running 5-7psi so different cooling requirements. I'd predict their charge cooler system wouldn't be up to much for track use, I think they are using the OEM 3rd radiator and they aren't all that good in my experience. I bet it all performs well enough though, it's not dealing with loads of heat.

i didn't add mines the 2.7 variant. not worried about costs as all previous cars have been heavily modified. remaps, HPFP. external accessories so the 6k cost is probably similar anyway i wonder what sort of 100-200 times this would achieve.
