well whos this guys mate on a 2.0 with a sc46 at 460 odd brake at 1.6bar....

wheres the graph...?

maybe with meth but still...

ive read the thread douche bag i have an sc46 myself at 1.8bar on a 2.1 prod 420 odd bhp hence why i cant believe the figure.

460 on straight V-power on a 2.0 litre is what i'm aiming for with my 46, hoping for 500 with meth

currently around 400-420 on tmic with V-Power @ 1.6 peak iirc

mine mate 424.8 bhp on v power and 459.6bhp on 16.6% meth.hopefully it will break 500 bhp when pushed as only at 1.6 bar at the moment

What sort of figures are people getting on a std newage 2.0ltr STI with the sc46. Im sure somebody posted but there are just too many threads to look through now lol

Im looking for the same thing dont know whether to go 42 or 46. Only used as a daily driver so don't want it to laggy.

Hi,

we have done loads of SC46 Billets on 2.0 ltr new age STI cars, they usually do around 420 BHP on straight "V" power and 450 to 460 on a 20% methanol mix.

If pushed harder with supporting mods there is no reason that they wont hit the 500 BHP mark, its smaller brother the SC42 Billet hit 475 BHP on a 2.0 ltr with 20% meth last week, its all there to see about 3 pages back.

Kev, what do you class as supporting mods?
Mines got GT Headers, 3inch decat, Walbro pump, FPR, Front mount, Inner wing induction, 800cc injectors, simtek.

Just waiting for the new year for the front mount to go on and with a bit 20% meth mix would you expect 500bhp?

The Gaffer

Hi,

yes stuff like that, but please don't set your sights to high and end up disappointed with 450BHP.

Remember its is an SC46 Billet rated to 460BHP, its the more aerodynamic, lightweight Billet wheel that they use which gives them the edge.

If you notice from page one of this epic thread the figures have got better and better all down to little tweaks on the wheel as they have evolved.

So im looking for 400bhp, no more, no less. Used as a normal road car on a std sti 2.0 with supporting mods. Which is best suited? Sc46? Or sc42?

Hi douche bag,

(somebody who you think is a complete retard and doesn't know what they are talking about) Apparantly.

Need you to pop in and see our bodywork guru, Steven, he has some very nice front wings to show you.

cheers

OOOOPS ....Must learn to use brain before mouth in future mate.

And by the way,it was an easy 460 with much more to come if he wants it.

if i was you bryn i'd go for the 42! Jon is running a 46 mapped safely to 420 so you have the same power with a slightly earlier spool

Lol I'll try Saturday cheers

Scooby B

iTrader: (2)

Yes that did cross my mind, but i did wonder why so much more people seem to go with the 46 over of the 42 despite keeping their cars around the 400 mark. Maybe the 46 would be best if you had plans to take it even higher in the future? But if i aim to stick at 400, the 42 is the one for me

wrx9181

iTrader: (2)

The sc42 hasn't been available for as long either budd
The reason I went for sc46 was because I want a stoker eventually
But as I said the sc42 was not out when I went 46

42 is a cracking turbo in twin scroll guise. Gives oem spool (spool just as quick as a smaller turbo ) , and give me an extra 60bhp+ 50ltb.

sc46 billet twin-scroll all mapped now the engine is run-in, but due to a "wobbly wheel" i cant post a dyno-run. The car got up to about 3500rpm and the wheel wobble sent the rollers into slow-mode. I will get the wobble sorted and api will try again. Propels down the road nicely though..

Shaun

Apart from your wheel "wobble" I'm pleased you have it all back and running well Cliff.

Enjoy your new engine and turbo mate.

Ok, something to bare in mind, thanks for the help wrx9181, juggers and Iain!

juggers

iTrader: (1)

Forget the rollers how does it go on the road and is it a noticeable improvement from before... Etc

I remember when I first put my foot down in mine after it was mapped and my *** started twitching

Hammer man

iTrader: (25)

I dont think it would be right to compare, as the old engine was a 2.0ltr sti and the new one is a forged 2.5ltr. The old engine block was sound, but the compression was stuffed due to bent valves, so Pat didnt want to map the vf37 to its max. The new engine is certainly more than I, (as a driver) can cope with. But to answer your question, its a bit like "chalk and cheese".

Hammer man

iTrader: (25)

Thank you Shaun.

juggers

Agh fair do's sounds like a great setup 2.5 and twinscroll

WhiteWagonMan

iTrader: (34)

There was an sc46 single scroll on a forged 2.5 sti mapped today by pat at the scoobyclinic which made an easy 464bhp and 480ftlbs torque if you need a comparison cliff.

Hammer man

iTrader: (25)

Im sure its there or there abouts. I went twin scroll for the low spool/high torque set up. It would be interesting to compare torque curves on both cars.

WhiteWagonMan

iTrader: (34)

I watched it being mapped on the rollers and it was remarkable how quickly it spooled and do remember it being at 360ftlbs at 3500prm,the 2.5 option must make a fantastic road car.
