Interested in the SC42 turbo for my forged 2.5 and would be interested to see if anyone has a dyno graph of their car or any car running this turbo and any feedback they could give?
Top one is my mates P1, 2.0 running alcatek ecu, blobeye top mount, 2.5in exhaust.
Thanks for the info John.
To be honest, if that's actually a SC42 turbo on your mates P1 then it would suggest he's using the wrong turbo. Should really have gone with the SC38 turbo for that level, especially as he's only on a newage TMIC which will limit things anyhow.
I've seen the graphs on the Scoobyclinic website, just interested to see if there any members on here with any personal experience.

He was expecting higher - got a front mount kit to go on now and hes changing mapper!!!

no dyno here as yet, curious though as regards to the sc42 interest, why are you not considering an sc46 or perhaps even the precision turbo?

Because I don't want to blow the bl00dy doors off!!!
Would rather aim just over 400bhp and leave a massive safe working limit as its my daily driver. 400-420 in this will be plenty for a road car. To be honest, the current setup actually works really well. It's so driveable and spools so fast it's crazy.
One of my favourite turbos for 400-450, great power band and spool is an awesome turbo imo. I bought 2 I liked it that much.
and that's on a 2.0 so on a 2.5 it would be pretty rapid.
in the wet I'd spin it in 3rd gear.
i think on a 2.5 a sc46 would be similar to a 2.0 with a sc42 as the 46 is more targeted for the 2.5, but a 42 on a 2.5 would be pretty rapid.

Excellent feedback thanks mate, just what I wanted to hear to be honest.

lol, fair enough, i thought id ask, do you have forged rods? has it had cdb conversion? been doing alot of research on this lately
I was also looking for graphs of 42's but mostly to compare with other similar sized turbos. I was also in contact with SC the other week there and they didn't have any stock of SC42's but had an SC42+. I originally wanted one but i;m going smaller to save on spool. SC might have got some in since then though.
That could be a problem then to be honest. They don't seem to list the SC42 any longer so their range is:
SC36 which they list as a 380bhp turbo
SC42+ which they list as a 450bhp turbo
And nothing inbetween this if you want to stay shy of 450bhp like me!
Trouble I have is the Perrin FMIC flows very well indeed so it could actually break 450bhp and I don't want to fit a turbo that is too large for the power I'm aiming for.

That's exactly why I started looking at garret hybrids from Turbo Dynamics, Lateral, RCM, Litchfield etc, I believe they are all built by TD but possibly with slightly differing specs.
Will try to find out one ,You should go with gt30 rotated with Your budget
Who do u use to fit turbo Kwikfit?
sc42+ is perfect i think, sc42 would not give 430hp
few hp more for few 1000£
the MDX321H is worth a look, mine made 441hp vpower/20%meth and spool up was just over 1.5 bar by 3700rpm. That's forged 2.5 with wrx heads.
I'm sure you'd get 420 on vpower with excellent spool up and be nicely within limits for the 2.5

Is that the billet version? That sounds like a very reasonable spool rpm for full boost. Is that using a FMIC?
