SC46 on V9 RA 2.12 stroker... on TMIC!
there are still plenty of things to do with that map, since I am only getting used to Autronic, but it shows the potential nevertheless

Hi,

great to hear the SC42 Billet twin scroll is delivering.

I know you keep thinking about the SC46 Billet twin scroll but I think the sacrifice in spool for the gain in BHP may be a little disappointing, remember its all about drivability, who wants 700 BHP that spools at 6000 RPM, OK for a track car but a snappy 400 BHP will be far quicker on the road.

Was thinking the same thing Kev.......think i'll just stick with this baby or wait for Hammer mans results before I decide

My sc46 billet twin-scroll is fiiiiiiiinally being mapped on Thursday,,, I`ll let you know how its gets on Kev.

nullfork

Well I'm getting mapped on the 28th, SC46 single scroll on a 2008 UK hatch STI. Standard injectors, but Bosch 044 & swirl pot - plan is to see if we can break 400hp (safely) on the standard injectors!!

Immy, you really need to calm down ;-)

juggers

iTrader: (1)

I know think am getting carried away! Would advise you to the the injectors done tho will make it future proof to and will not hold you back.

Can anyone tell me what bolts/ studs I need for an sc36 billet between turbo and manifold- there are three and no idea what size or pitch to bolt into the thread on the turbo

nullfork

Thing is, I doubt I'd safely see any more than ~425hp on the TMIC, now with the increased fuel pressure that I'll get from my secondary Bosch 044 fuel pump I reckon I can get just over 400hp on standard injectors, so I figure it's worth waiting until I go FMIC before I touch the injectors. Also don't forget the 2.5s run hotter than the 2.0, so probably even more need for FMIC (IMHO).

Other thing is, as I said to you the other night, I want to get "used" to ~400hp first, then when I finally go ~450hp it's a double bonus, I know it's another mapping session but...

ANYWAY, it will be a good comparison against your motor if mine is mapped to a same HP level as yours

btw, slightly OT: really liking the full HT autos kit, do you know if they're doing the front splitter for the 08 yet, last time I checked it was for MY10+ only?

The Gaffer

Hi,

its 10 X 1.25, we have studs in stock made from stainless steel at £3.50 each.

cheers

Good luck mate and may the boost be with you!

Hi lads,

Although I have gone through quite a good bit of info in this thread I was wondering what turbo to go for my fully forged 2.5 ?I current have a vf35 on it which is useless being honest.

Now Im not going 6 speed just yet but would like a turbo that best suits a 2.5 and i'll kee the boost down for the moment to conserve the 5 speed and clutch until i have funds to get the 6 speeder

I was thinking the sc40 ? Or would the Normal ball bearing sc46 be better?

Thanks in advance

Barry

Fair do's make sure you call me on the 28th will come and meet up and have a little play

The splitter is available for the MY08+ I shall have one on my R205 later today or tomorrow. and will post pics.

Hi,

SC46 Billet.

Stunning on a 2.5.

Cheers

Seconded .... the 46 on a 2.5 is epic!

However, it conservatively made over 400ftlbs so that 6 speed cant be too far away! :-)

Baz82

Maybe sc40? My target with this engine really was between 350-400hp and have it reliable for years

The Gaffer

Hi,

we are just about to test a new SC38 Billet ball bearing cored turbo on a 2.5, we reckon spool will be as good as the SC 36 Billet with the power of an SC40 Billet.

Here's hoping at least.

cheers
Kev

Baz82

Brilliant i will be keeping a close eye on the thread

Thanks

Cheers Shaun. Im looking forward to the drive home
2.5 forged with all the "bits and bobs" and sc46ts billet.....I`ll take "stunning".

Yup agreed,it will be awesome on a 2.5 with supporting mods,my mate has a 46 on his P1 2.0ltr forged and made 460bhp with good spool at 1.6bar with loads left in reserve,fantastic turbo without a doubt.

New_scooby_04

iTrader: (4)

If you have the right supporting mods:breathing, fueling etc.. then SC46, no question! Mine made 470/480 and develops 1bar boost at 2700 rpm. It's everything you could want in a turbo for a road based performance car!

Baz82

I have 740cc Injectors (future mods), Autronic SMC, Fmic, Decat end a full 3" exhaust and Apexi Power Intake

To be honest I want between 350-400hp from this engine as I'm still using the 5 speed box, I know the torque could still kill it .
Also going past the 400 mark I wouldnt really have the funds to start changing to brembo setup and larger wheels etc.
