littco 700

 

These Littco 700 turbos were fitted on a 2016 BMW M4 with eu5 F10 M5 injectors making 660bhp on 99ron & 740 bhp on E30. This car also had crank hub uprated & the plastic charge pipes replaced as they are prone to cracking. 

Littco 640’s & Littco 700’s are good value for money, especially when the stock units oil seals can start to fail these are a good alternative to replacing with another set of stock turbos.

Pure stage 2 + s55

Here we have the famous Pure Stage 2+ turbos, These have set numerous S55 records around the world. This particular set found their way on to Europe’s fastest convertible M4 making just over 800bhp coupled with a 8nozzle Torqbyte meth injection kit. If you want to make big power with a S55 these are not a bad decision.

 

Dyno Engine mapping from £550 inc Vat, Most Stage 1 cars achieve mid 7 sec 100-200kph & Stage 2 cars high 6sec 100-200kph

 M3 M4 & M2 Comp all come with the s55 engine, Mevd17.2.G engine ECU and we are able to offer a multitude of packages to suit all customers, for stage 1 or stage 2 charge pipe is recommended & when adding meth or turbos the crankhub fix needs to be done. Options like burbles on sport mode, cold start delete & speed limit removal are all possible at no additional cost.

 

We offer ecu unlocking at a cost of £240 inc vat, and can provide bm3 licenses and custom mapping on their platform for those who would like map switching.



We offer engine tuning suited to a customer needs whether its all-out power or a smooth usable track orientated remap, for the rest of the vehicle GTS programming as such gearbox, steering, diff is reprogrammed to GTS settings or the more aggressive xhp gearbox softwarer can be applied. Uprated charge pipes, uprated spark plugs, decat pipes & general vehicle coding/ servicing is also available. From late 2020 XHP Gearbox stage 1,2 & 3 became available  also.

We have tuned this engine in many cars from the small nimble M2 comp to the track orientated M4 cs. Carrying out Stage 1 tuning all the way to fire spitting hybrid turbo and water methanol fuelled combinations. 

Frequently Asked Questions 

  • Do I need a Crank Hub for a remap?

At Velocity we require Crank Hub fix for Hybrid turbo or race fuel setups, it is not a must for Stage 1/ 2 but it is possible for even Stock vehicles to slip crank hubs. 90% of our customers do not have crank hub fix and have no issues but there are many cases online of people having failures.

  • Will a capture plate reduce risk of slippage?

Sadly no we do not recognise a capture plate in being able to reduce the risk as failure is normally a result of the friction washer deteriorating/ breaking and not the bolt winding out.

  • What spark plugs do you recommend and why?

We recommend the NGK 97506 plugs gapped to 0.022, the reason for this is the stock plug and gap unless in optimal condition is prone to causing misfire under boost especially when tuned. The tighter gap and better NGK will provide a stronger spark which we use on all S55 from stock to our high power builds.

  • Do I need uprated charge pipes?

We do recommend changing the charge pipes, being plastic and on top of the engine they become brittle due to the heat cycles and are prone to cracking resulting in a loss of boost. They do not add power this is purely to prevent the OEM unit breaking as it ages.






white_m3_stage1

 

Stage 1 remap requires no physical changes to be made to the car this is software only and sees a huge gain in performance from standard power.

 

Stage 2 remap requires as a minimum decat exhaust, some replace charge pipes for harder than stock as they are prone to breaking and there is options to upgrade the charge cooler itself
