Does anyone know if this will fit on an ST?

http://www.autospecialists.co.uk/Stainless-RS-Mk2-top-induction-pipe---New-easy-fit-design-Product-1046.html#

It's the right shape for what I'm looking for and follows the route across the top of the engine I need but it looks,like,the sensors are on the opposit side of the pipe, if they are the same as the ST sensors, it maybe they aren't?

The ST one AS list doesn't follow the same routs, it's athe same route as the standard pipe which is wrong for what I want.

I'm sure there are some on here with Stainless induction pipes like this?

I think the sensors are different, plus when I did my RS airbox setup like monkeyrider before me, he alluded that the ST MAF should be in the same area as the original so as to avoid problems with it reading incorrectly

Hey mate. Pretty sure this is one which Fishy used and then removed recently because it was messing something up. He's now using the oem RS pipe with the AS RS intake.

I'm sure he'll be along soon to clarify.

Yeah that pipe is for the RS and can only be used if your software requires the use of an RS MAF. If you are making something custom, make sure to keep the distance from turbo to MAF roughly the same.

Thanks for the advice all.
Nothing is ever straight forward when you start trying to do something different.

May have to rethink my plans a little.

Distance from turbo to MAF is not really an issue. I've lengthened my MAF loom and tested this, it ran perfectly. The problem with RS turbo pipes is using an RS MAF, it won't work without custom tuning as it is a different sensor.
Another problem is if the relationship between the sensor and pipe size is wrong. If the pipe is less than 3 inches on a highly modded ST, air moves fast and gives a higher MAF voltage which can top out early and throw it into a kind of emergency limp. The ECU slams the throttle shut because it can't get a useable voltage reading past maximum output.

A 3" turbo pipe allows the MAF to run at a slightly reduced voltage than stock as it slows the air down a little, this gives some headroom for increased turbine performance without maxing the MAF voltage and it will trim fuel settings to keep air/fuel correct.

I think I'd rather believe the advise of several of our top tuners. It may cause issues on some cars even if yours runs ok.

Good points regarding the pipe diameter though - something else to consider if making a custom kit.

I don't really want to run an RS maf to be honest, it's not that complicated my requirement. I just want a stainless steel pipe that follows the same route across the top of the engine but will fit the ST maf and connections.
I imagine getting one fabricated from scratch will be expensive. I may look at getting mine powder coated when I've thought about it a bit more.

Bang on the money Mark! It caused some issues with our setup that couldnt be got around! I think its to do with the diameter of the pipework! I certainly wouldnt recomend fitting one even if you can run the RS MAF sensor!

I had heard from a respectable tuner that its mainly down to the diameter of the pipe that causes issues which could be down to the extra diameter would mean more air would be going past the MAF which affects its performance and the ECU cannot deal with, that just my theory and given that I'm normally way off the mark its probably wrong but I will stick with the ST pipe work till I need to go RS induction

That just about sums it up!

I had a look at this offering from Injen, contacted them for parts price and shipping from America for just the pipe, and was coming in at around £140.
I didn't go ahead with it as I hadn't heard of anyone using it and I can't afford to buy it then for it not to work.
It does look more direct than the standard and AS offering.

Whats wrong with the pipe you have got on there already James? Is it just that your wanting it shiny? Why not have it crinkle finished to match the inlet plenum?

I just like shiny things Nick.


I'm thinking I may go for a crinkle finish though.
I'm thinking of doing some engine dressing as my next project on the car, woul be nice to do something different.

Fair comment mate, I cant knock that. I think a nice red crinkle finish to match the plenum would look well smart. What is your crossover pipe made from?

It's steel but it just looks a bit unfinished being a prototype. I may ask Pumaspeed who did the powder coating on the Plenum and take it to the same place.

Ah! I couldnt remember what material it was made of. Im sure you can spray crinkle finish yourself James. If you get the paint I will spray it for you for free if your not confident spraying it.

Didn't know that, will have to look into it, I'm sure it wouldn't be a difficult job.
I will check it out too James, im sure I have read you can get crinkle finish in a spray can. It would be easy mate.

Chell has just told me B&Q sell it (aisle 24 in Doncaster branch) its by Plastikote.

like it!
I've done a quick search on google, you can indeed buy wrinkle finish paint. I may get some and have an experiment after Xmas.
Think ill do a couple of trails before I paint my induction pipe though.
