Sc42 turbo single or twin scroll on a 2.0 sti
 

Seeing as kev's taking me round in circles, i thought i'd ask here

Looking for dyno graphs with people using a sc42 turbo either single or twin scroll 2.0 sti using tesco99 or equivalent (no meth)

Id like to see how it compares to my twin scroll

Thanks

just to throw another spanner in the works for you sc46 on a 2.0 with AVCS heads. Car had exhaust and intake restrictions at the time

2.5" downpipe might lose you 5-8bhp, but it will help you hit boost sooner. Intake isnt restrictive at this point. For reference, on the dyno, im 100 rpm behind you, but i make a few ponies more on a smaller turbo, no avcs

The turbo intake wasn’t the best under boost. Exhaust had 3” decat then to 2.5” adaptor onto a 3” system.

Must be more people running a sc42 turbo

Or sc46

Have you got a graph we can have a look at?
I've been doing some map tweaks today to see if I can get my sc42 ts to boost a bit earlier,I will take some logs tomorrow to see if I've improved.
I'll get mine on the rollers when I'm happy.

I dont use a scooby clinic turbo. I want to compare my rcm twin scroll to the sc42 single or twin scroll

I am looking for more torque and hopefully earlier in the rev range. Not that i need it. My car drives superb as it is

Did you manage to take some logs?

Thanks

I took a pull on my old set up,did some work on the map then the laptop crashed,sorted that now so if I get a nice run on the way home from work I'll log the new map to see if I've improved much,I've only tweaked wg duty so I don't expect much gain.
detcans need sorting and my afr sensor is shagged so I don't want to mess with fuel&timing,I recon I can go more aggressive with timing so should improve torque.
I've got virtual dyno software too but need some spare time to have a good play plus some proper runs.
Still it would be nice to see any graphs you have of your RCM TS if you can?
