External view of the sender which is inserted through the silicon pipe into an aluminium joiner.
The sender viewed from inside the pipe. It is screwed into the aluminium joiner and araldyte is then applied.
Ian if you still have any questions on the installation I suggest you e-mail me.

Temp at throttle body 196 deg C
Designed to use Methanol as a fuel but run on Optimax at 2 bar boost during testing.
Effects on combustion ? Lets just say I no longer worry about using a charge temp gauge

you say that the charge gets warmed up even after being chilled by IC before it gets to combustion chamber by the intake plenum. It is aluminum cast manifold - it gets its temperature conducted from the engine were a massive amount of heat is generated. So, why I.cooling the charge then ?
Anyways the charge temp can't get lower than some Greatest Lower Bound temp which is characterized by the intake manifold.

So, DRM supply the scoops, where do you get the undertrays from?
On my 03WRX, to swap to an STI 8 scoop i assume requires the same undertray?
Also, is the STI 8 TMIC a straight swap for the WRX one, or do things have to be modded?
Next, lol, what 'real' world gains would be had from fitting the above when compared to the WRX scoop, TMIC, etc.
Car is:- VF34, 550 Injectors, associated mods.

Various places sell undertrays
JW Racing Under Bonnet
Zero/Sports Cool Action Intercooler Splitter (Subaru Impreza WRX) [ZS-0306010]
The OE Sti tray is not bad, or you can DIY modify your WRX one to fit.
The Sti intercooler is a direct bolt on to your WRX, the WRX mounting bracket has 2 different holes in it, one is for an Sti intercooler
The new age WRX intercooler is good for around 325bhp on an appropriately sized turbo before it struggles, the 45% larger Sti unit will bring significant gains with a VF34 etc
Typically I'd expect to see 330-345 bhp on that set up but if you like I can tell you a rolling road that will give you nearer 375

Another question about fitting the sti8 tmic to an 03 wrx. Dont i need another hose or set of hoses to fit this?
Atm, i have some samco hoses that connect up my wrx tmic, but surely these dont fit the sti tmic?

Ta for that
Is the sti ic likely to lower the spool up point of the vf34 when the car is remapped? Only as it is now i feel the spool up is 'late' up the revs and so full boost arrives later than i would like. (may be total b*ll*cks like)

Take your pick from VF23/24/28/29/34/35 or TD04H/TD05-16G turbos, uprated fuel pump and an Ecutek remap. Your existing 440 injectors will be fine.
Turbo's stacked in order of full boost response from approx 2500rpm to 3300rpm
04h
35
24
28/29
16g
34
23
This order is also pretty close to the order of increasing power capability in the range of 310-350bhp

As an added note regarding measuring inlet temps,apart from the previoulsy mentioned set up as used by harvey etc there is a nice cost effective number to be had from maplins..... i use one on my modded wrx,costs less than £20 delivered,runs off a AA battery that lasts a year before change needed,no back light unfortunatly,but as night times tend to be at cooler temps than the days im not that bothered..... the temp probe ive mounted into the intercooler pipe to throttle body,simply drilled a small hole,pushed the probe in and secured with a little silicone sealent,let it dry and its been there over a year now doing a fine job.... it is alarming at first seeing the temps rise esp at stationary times due to heatsoak,but generally they are well in check on a my00 with a tdo5 and a 2004 wrx ic,plus lots of other bits and bobs......

Well agreed Harvey its on the cheap side,with slight limitations regarding back light and night time use,battery life i can live with at over a year on the original one, it lasts a long time.... without buying an all singing and dancing one and mounting that along side i cannot verify its accuracy.... its a measuring instrument after all that i hope would have been calibrated to roughly the correct scale before being released for sale.... as an indicator tool it does its job......

With an uprated fuel pump you should be able to safely achieve IRO 320-330bhp, any further and you are running the turbo out of its efficiency zone. This will be obvious during mapping from airflow and wastegate duty data, no need to fit an air temp gauge if it is mapped correctly with an appropriate safety margin for your particular set up.
Some seem to love an interior full of gadgets and gauges, I personally hate it, it detracts from my driving pleasure ! Maybe I just see too much data in my day job
Theres not one extra gauge in my Spec C and thats running fairly highly tuned.
If you want to monitor anything I would have EGT and AFR and boost at the top of the priority list.

I would think, although obviously driving it is hard to do both, but trying to watch my boost gauge/revs, etc, i would say mine is not on full boost until 3500 or even more. but to be fair, i would need someone else to watch the gauges whilst i drive to know for sure. LOL.
My main complaint with my car is the complete lack of anything before 3k revs. I think my headers have robbed me of any torque at all down there.
But i always was a negative f00ka.

I wouldn't do anything to it on a std fuel pump I've seen std decatted Sti3/4 running lean due to lack of fuel and boost creep, they were making good power (but not for long)

how much would you ask for a good engine tuning package for fast road?
where are you located?
thanks
cheers
