so i am sure this has been over a few times, but anyway as i will soon be getting another map tweak from duncan, have heard a few times that over the oe inlet hose under the inlet manifold, if this is upgraded to a samco hose there is deffinate gains to be had allbeit small, not particularly just talking about ponnies here but better smoother airflow and so on.

only running the standard size new turbo is a billet 20g t51 hybrid and am hoping for a shade over 400 on the blob sti, so thoughts on worththe extra 200odd before mapping the new turbo in, currently run a vf48 on the oe hose with japspeed wing kit and k&n filter is being replaced for a foot long one as well

 

From what I've heard the Samco one is not wire reinforced so is prone to collapsing under load......the SFS one or the Perrin one will work and there are gains to be had!

 

I'd do it youve got some nice supporting mods there the hose will complement the turbo as said
Perrin
Samco although I'm sure the size isn't as perfect as the perrin
Aet do a solid intake but I phoned dsa on Thursday and they haven't made or had any in ages
Lateral makes one but it doesn't have take offs for breathers or dv so you would need an oil catch can
His are made buy sfs to custom specs

If the existing one is in good condition with no leaks, leave it alone. It can be a PITA to change (you may need to lift the manifold) If you intend to use a turbo with a big inlet (76mm) then of course, you need to change it.

does not bother me removing the inlet and engine loom etc, needs a good clean around the back anyway lol.
but when you look on the bay see loads of sellers(some well known) selling for around the £65 mark then the samco one at a good bit over 200 i have heard from a few people to get the samco one due it being re-inforced and wont collapse/suck in? seems strange at that price if it is not can anyone with one for that price confirm?

also a few subaru's back i bought a cheap one at £50 cut it in half and inserted solid steel to stop the above from happening, but sure that would affect airflow somewhat but as to how much no one will ever know unless it was back to back tested

 

i have two mates both running circa 500bhp with garret turbos and the samco turbo inlet hose? both mapped from andy forrest, so am struggling to believe these collapse?

 

Have a look at Viper Performance?

Hi Grant

As above Viper is good Inlet hose,Perrin or Samco will be good choice too,if you can get them for good price

About those cheap inlet hoses,i've run cheap Inlet hose on our wagon before at 1.5bar on VF34 without the problem,but after we are went with MDX321T we are went with custom Inlet hose from alloy

Jura

 

thanks jura, the viper ones look good i have to say but have chance at a samco for good price but dont want to make the wrong choice, needs to be the right thng over price eh, want the most from new billet turbo

Grant

 

Hi Grant

Samco people mostly prefer and really i've never tried this myself and due this I cannot comment on that

As I said,you can make yours own one from Intercooler pipework and few silicone couplers



Jura

 

hmm thats a good idea, silicone joiner from turbo to fmic pipework under inlet with corner then another silicone joiner to maf dont need all the outlets anyway as habe a greddy catch tank fitted hmm good idea that, you know anyone thats done this?

 

Hi Grant

We are run this on our wagon at 490bhp and 1.7bar without the problem



For us this made Neil@Slowboy Racing,try PM him or email him,hope he will help you sort this


Jura

 

thanks jura i like it, thats what am going to do now
