yes "thread"

sorry for my "bad" English. I live in Belgium.

I'd be willing to bet your English is far superior to either his French, Dutch, German or Flemish...ignore him :thumb:

- My apologies. When I posted that, I did so on my Android phone's SN app i.e. it doesn't show location.

- On the contrary, your English is a damn sight better than half of the 'natives' on here. :D


And yes, you're both right (about my 'other' languages). :razz: :D

Hi,

been a while since we posted on here so a bit of catching up to do.

There have been a few new turbos, tested and added to the range so I will update this thread ASAP.

Cheers

:D

anybody running a sc42 on a 2.1 stroker? wondering if it is laggy or not for a fast road (non-track) car with avcs heads

They never were anyway, but I suspect the new version on the horizon will spool like a B*****D !

so it would be a good choice for a fast road stroker then? any others worth thinking about?

A friend has an SC40 on a 2.1 with non avcs heads and that spools like a mutha fooker !!

Not been on here for a while as I have been more than happy with my SC42 Twinscroll. Whats the new news? Also I am thinking of going FMIC or for a Chevron F1 tmic can i go for a bigger turbo?

I thought sc42 was good on 2.0 litres? What would full boost be on a sc42 non avcs heads gt specs and Hs up pipe any ideas mappers

Kev, you sure know how to keep us bunch of idiots in suspense! :mad:

;) :D

Hopefully Kev's going to be useing my scoob as a test donkey for the new bearing core sc36.....

:cool:

That's surely gonna spool like the proverbial scalded cat.

like **** off a teflon stick

May be worth checking the Grimmspeed topmount out as well.

I am running SC46 on a 2.1 stroker with AVCS heads
not laggy AT ALL! On the road I was hitting 1.5 bar @ 3800

I would imagine SC42 would spool even faster

Looks awesome mate,what bhp/torque you got? Would a gt30r be laggy?

Thanks Martyn ;)

Looks like 502/413 in that pic; if that's on V-Power that's a nice figure from an SC46 :thumb:

seems a low torque figure

It's not bad; a decent exhaust will help.
Mine hits full boost about 4200RPM on a STi 2.0 with AVCS, and went on to make 439/385 on V-Power.
Simon reckons it might see just a wee bit more on a 3 bar Map sensor ;).
I think on the road it's more like about 4000rpm.
As your block is forged and you'll likely be running more boost than me that figure might improve again :)

pump RON98
we never finished tuning the car
as I later found out it made that power on only two alive pistons, so I tore the motor apart

I am doing the 2.12 again during winter, same setup only now with FMIC and JUN AVCS cams, so we will see how the SC46 does :)

for reference, this is what the pistons looked like

what happened?

detonation
what surprises me to this day, is that is happened almost instantly after the motor was built, as my catch can was smoking from day 1... with a break-in map with almost no boost and very little timing

so no idea really

hhmmm, did the builder rebuild it for you?

I would say those sharp edges on the valve cut outs are just asking for pinking to occur. That and the extremely thin piston wall caused by the cut outs is just asking for trouble. If it happened so early was the compression ratio correct from the build?

yes, I said to myself - you gotta rebuild it! Couldn't say no :)


yes, this is the conclusion I came to as well
despite how nice and light those diamond pistons are, they are just too fragile

I am going with Cosworth pistons for the new build
I checked for compression after I was tired of draining oil from the catch can, I knew there could not be that much blowby, and it was gone on two busted cylinders

Looks like they got the design wrong it's probably better to break out the valve cut out fully on the piston wall. Easy for them to do on a billet piston to. Guess they think the anodising will save the piston.
