Sc46
Anyone running one of these on a 2.5 ? Just after power made and what boost?
Thanks maz |
Heres mine.... happy with it!
Very conservatively mapped to protect the standard liners! Running CP pistons, standard rods, standard crank. http://i283.photobucket.com/albums/k...cyrollers2.jpg |
Think 460hp480 torq
Is the benchmark on 2.5 with sc46 Really 450/450 is ideal on 2.5 From what I'm told and learnt etc over the years |
For more power, id say you need to look at pinned blocks or closed deck inserts.
440/440 is great on the road though, and usually 'enough' on track! |
Thank you guys ! :thumb:

Here you go maz, built and pinned 2.5 block. Mapped to a very conservative 1.4bar. Makes 400/380 and is a hoot to drive. Your more than welcome to meet me up at crossroads and have a play yourself to see what it is like. Eventually the FMIC will go on along with one or two bits and will see what's left in it. Have heard it said that they are typically 480/480 on pump fuel and over 500 on a meth mix

No mate its on a perrin induction kit. Makes a lovely sound to :-) if I ever get the full spec list I will drop you a message.

Lol !! |

Great graph Martyn.what supporting mods fuel etc?
|
Blimey Martin :norty: great spool up !! I have seen that blouch in the USA do the 10cm2 housing ! You mapped any of these ! Just wondering if there is much difference in this and if its worth waiting for shipping !!:wonder:
Cheers maz |

Mine`s a twin scroll 46 and a 2.5 engine. Only graph I`ve had done after the build, and only v-power..

Built 2.5 Hatch engine, stock heads and cams, SC46, Ecutek inectors, Perrin front mount, K+N induction kit, 3 inch system, mapped on Racerom.
In my experience the 10cm housing doesn't improve that much on power and loses a bit of spool, the new 7.5cm cast housing ala Scoobyclinic is very good. |

I currently have a decat downpipe but standard centre and back boxes on my Saloon. Would that hold it back as I have basically a similar spec minus the FMIC which is on the cards so would be curious to know if I will have to replace the rest of the system or not? Or maybe just the centre to help it flow if need be, any advice would be great. Hoping not as it's nice a quiet, must be getting old lol. Also what bar was that mapped to? |

Lol,no not yet , back from Gambia this Friday night ! Got free wifi here on the beach so it's rum and coke and free surfing ! Been looking at turbo,s , engine builds, double din satnavs :norty: :D You seen marks 2 door type r ? |
You got any used tyres for me ? 225 , 17,s
|
no only seen pics of it as for tyres you need a pair or four??? thought you were after some 18's???
as for sat navs sorry dude but you know whats it like where i work we dont buy direct or in bulk let us know what you need and ill see what i can do |
No worries !! Might keep the standards for a bit and concentrate on chasing the numbers game !! :-) !! Can't stop looking at turbos and engine builds :-)
|
handling and brakes can make up for less power though think im gonna wait a bit more till i do mine so useable at the min
|
Usable yep but still want rb5 power :-) !! Oh well !!

A while ago we fitted an SC46 to an RB320. On the topmount it made 402bhp at 1.4 bar, on a Perrin front mount it made 445bhp at the same boost. |
Mine made 404/421 limited by the top mount.

A full system should free it up a bit but the intercooler is more likely to be the limiting factor on yours.

Appreciate the help and advice |
Whilst I can't speak for the MY08> OEM inlets and TMIC, I know the previous Newage TMIC is not a limiting factor (Andy Forrest for instance retained the OEM TMIC and exceeded 450bhp iirc) for more than 400bhp - based on logical deduction it appears to be the inlet side for that range of set-up. On the MY08>'s I'm led to believe the inlet is certainly a restriction.
This is assuming all things are equal, which with the most important element of effective mapping, is not always the case (as in who you use and what hardware is being utilised). |

Whilst it may be the combination of the inlet and intercooler that actually increases the power so radically, I'd always be more comfortable over 400bhp using a good quality front mount :thumb: |
