Just when you thought the BMW M5 couldn’t get any better than it already is, Currency Motors goes and adds a twin turbo charged engine giving the BMW M5 a huge boost with 815 horsepower. While it will cost you $350,000, Currency Motors adds a hand-built intercooler system, a full custom exhaust and two turbochargers, giving you the ability to reach top speeds of 240 mph.

The two turbo chargers are placed in the rear bumper while the SMG transmission was left untouched. Inside the Currency Motor BMW M5, the car gets aniline dyed Florida crocodile black leather. If you plan on buying this 815 horsepower beast, get your order in quick because Currency Motor only plans on making 10 of these at the moment.

For being such a high-end, costly kit, they sure don't weld up the piping very well. :indiff:

Very cool idea though. It reminds me of the kit I saw in Honda-Tuning magazine, some company made for the Integra Type-R.
 
what the heck is up with people puting the turbos way out back like that? whats the bennefit? and does it out weigh all the problems. this thing CANT have verry good throttle response. and i though it took long enough for turbos to spool when they were bolted to the exhaust manifold, talk about turbo lag.
 
Hmmn Sounds way overpriced, do they include the whole car in that price!?

I assume the standard high compression engine requires a full rebuild suited for the turbochargers.

I'm sure it is as fast as they say, but I sure hope they include a free engine the first time it blows up.

I hope so for that price.

Plenty of room back there, probably too squashy up front and even of the do just fit them a lot of heat will build up.

1. Colder engine bay temps. (less need for an intercooler, and less wear on the oil used for the engine itself)
2. Colder turbo temps. (less chance for the bearings to seize, less chance for the exhaust side to crack from overheating)
3. Small enough turbos spool quickly enough on larger displacement engines, that it's harder to notice the turbo lag, when compared to a closer mounted system, with all the benefits of having the turbos remote-mounted.
 
Not bad, though I think I'd rather go somewhere else like maybe Dinan or AC Schnitzer to do a twin-turbo job unless they can prove they can hit 240Mph.

I'd also probably change the rims, but I do applaud how the car wasn't given any flashy exterior add-ons.

True enough, though I'd be concerned about compressing all that air between the turbo and the engine.

That air is already compressed.

Also the long tubing is a bit of free intercooling.

These guys did it first (vids at the site, but for mostly GM products and some Toyotas).
