Martyn - How would I know if the AVCS was or was not working? Apparently the TiP was one of their newer versions which is stronger, but I'm not so sure. Might have to look into getting a different one

JGM - I thought it was going to be much more technical than that haha

 

If you compare peak power rpm to another similar spec it seems to be at higher rpm.
Therefore maybe the rpm is 500rpm out which would put spool where it should be.

No easy way to check vvt without a laptop

 

Looks mega laggy compared to my 46, also 14 to 1? is that a bit lean even for low power?

 

JGM - Before I started the engine management light was on, I presumed for fuelling but apparently it was cam position sensor, but once turned off it hasn't come back on, could that be the issue?

Tidgy - I presume you're is a hawk with a 2.5 so not really comparable, and I have no idea where you got the 14 to 1 from? unless it was a typo and you mean 14 to 11, but I still don't really know what it means haha

 

14 to 1 comes from the graph you posted mate

 

His fuelling graph looks find Tidgy.

The 14:1 afr is off boost at start of the run.

 

Martyn how did you reinforce pipe with alloy pipe inside?

 

yeah yeah i know its off boost, just highyest i've ever seen the ratio even off boost thats all.

 

My fueling is about 14.1 off boost looking at my graph

 

Cruise should be and being laggy you get a bit of cruise at the start of the graph

 

Tidge wtf have you been smoking dude its perfectly normal,unlike your way of interpreting a dyno graph obviously mate.

 

Shut up man, Tidgy is clearly an expert

Kev
On the same 2.35, how much later in RPM would the Latest Billet 35 spool be than the Billet 30 0.63?????????????

 

Carefully placed jubilee clips on the outside of the pipe to make it retain shape.

 

my old car,

 

Come on Kev - This thread is worthless without more turbo testing and more graphs!

 

That graph shows you around 14.4 AFR cruise which is fine then as the boost raises around the 2.5k RPM range(td04 at a guess) the AFR drops as it should do to 11 in boost, Well that's what I see

 

Tested a couple out in the world this week. They were both rubbish.

Graphs uploading

 

Sc42 2.1 newage sti alcatek


Older Sc46 - 2.5 so boost kept lower to preserve block hawk sti syvecs


Higher 20%meth. Lower vpower.

 

Thanks Si, if that was rubbish perhaps you could try a bit harder LOL

Simon, Do you have any graphs of a twin scroll 42 on JDM 2.0 with OEM top mount?

 

Lol

 

Dont think I have sorry

 

Been looking at the SC turbos. I have an Impreza WRX 2003 looking to get 350 bhp ish, what turbo would suit best with supporting mods SC32? SC36

 

SC36 works very well at that level.

 

Thanks, What price are these Turbo at the Moment?

 

Here ya go matey.. http://shop.scoobyclinic.com/index.p...product_id=127

 

What would you recommend for a built2.5 and oem Sti topmount.

Looking for response and 400.

 

I know you didn't ask for this, but on a built 2.5 I'd suggest go with a FMIC and a bigger turbo.
The TMIC will get you near to 400 and acceleration and spool will be bonkers on a 2.5, but tbh with the 2.5 you won't suffer from the lag you would on a 2.0 with a FMIC fitted.
And the extra torque will bring it through.

I'd have said buy an SC42 or even SC46 and go FMIC with that setup.
Good for 420-430 all day long on the SC42 and 460+ on a SC46.

Add meth and you're looking at 500+. Just a thought

Ask Simon, I know he's mapped a load of these turbos and recently did a Hawk with an SC46
