Anyone running an SC42 on a 2.5, if so what's it like please?

 

Hi,

we have done a few SC42 billets on forged 2.5 engines, one word, "stunning", who needs the brag figures when the spool far out ways them.

Its a great combination and surprised us to be fair as the SC46 Billet was designed for the 2.5 and the SC42 billet for the 2.0 and 2.1 stroked engines but it seems to love the 2.5 as well.

As stated earlier in this thread, lots of research carried out this year, a few new aero blades now out and the latest cast 7cm exhaust housing seems to work well.

Will update everyone over Xmas,

Have a good un

cheers

kev,what would be better suited for a fast road 2.1 with avcs heads? sc42 or sc46? a few people have mentioned the gt30 but im guessing that would be laggy on a every day car

cheers

 

SC42 or SC46 will both work on that set up, GT30 will make big numbers but at the extra cost of a rotated kit and some lag, it will however make more power at less boost.

Cheers

New Turbo's for 2014?

 

Hi,

not updated this thread for a while but it seems to have a life of its own regardless.

There are a number of new turbos to add to the range this year, an all new SC42 billet + under going testing tomorrow.

The graph below shows the improvement with regard to spool on the SC46's new cast housing, never was the SC46 Billet a slouch at spooling but the new cast housing has improved it by around 500 RPM without affecting the power figure at all,

I know that its not a full up power figure but we don’t want to push harder on this car as its on a standard 5 speed gearbox.



But just look at that spool,

cheers

Tidgys 2.5?

 

kev,what would the sc46 be like on a 2.1 stroker with avcs heads? fast road use only.

 

oooo hello, didnt realise it had been done yet. Top mount is def struggling then hahahaha

God damit, gotta wait till sat to pick it up

 

That's a yes then...let us know how it feels compared to the old one pls

 

shal do

 

What price off the new sc46

 

Hi,

SC42 billet + should be better suited, testing one with some small changes tomorrow......

cheers
Kev

good stuff,get the results up

 

Any news on the new sc36 kev????

The fat f**ker never gets me what I want.....lol

 

Then be sure to kick the beard-botherer squarely in his jingle bells next year!

 

👍😄

 

Hi,

as promised SC42 Billet + results...................








This is on a 2.0 ltr STI bug eye running a FMIC, on shell V power, we didn’t bother with road test as the turbo is coming off and vehicle returning to standard, spool would be expected to be around 500 RPM earlier on the road.

Think we have a winner here, wonder what the SC46 Billet + is going to do.

Cheers
Kev

 

would the spool be earlier with a 2.1?

oh and 485bhp from a sc42............wtf to that

 

Yeah, and that's on 'lowest denominator' spec i.e. 2.0 and V-P only! Christ!

 

be interesting to see what the rest of the car spec is

 

Hi,

rest of the car is standard, just a FMIC, a perrin inlet pipe and V power, mapped in house by Andy our Pat trained mapper.

Spool will be improved on a 2.1 but as to how much I dont know until we rtry one

Cheers
Kev

 

Pat.
And Mini Me Pat. Pat's pet lol.

We're getting spoilt now!

 

i went for the billet sc46 on my forged 2,5 with full supporting mods and have been dissapointed in the spool and power achieved tbh
mine is a ej257 cdb forged build with rcm headers/fuel rails/injectors/reg/pump/tgv delete/harvey uppipe /hdi fmic and intake /perrin turbo pipe/simtek and only achvd 445bhp and noticeable lag
mapped by steve simpson so doubt its the mapping

 

good result but isn't the boost a bit high for a standard engine, amazed the heads have not shown signs of lifting, would have thought 1.7 bar would be about as far as you could push it and stay safe. Still on a standard ECU? What injectors?

 

mine with the previous revision wasnt exactly laggy, got some graphs?

 

no graphs just my bum dyno
its not a slouch but was hoping for more snap
tbh i thing best combo for road is tmic and sticking to a sc42 or equiv max
the fmic causes too much lag
