Yeah if you think about it in simple terms
As I'm simple , a pipe would not suck closed if the air was coming though filter at rate it's being pulled in .
Ie a vacuum must be the problem, logically ?

Yeah, air being sucked through at a high rate causes a very low pressure on the inside, whilst you still have a relatively high pressure on the outside (despite the forward motion of the car). Net result is that a the pipe can collapse due to pressure always wanting to equalise i.e. high pressure rushing to low pressure areas...

All this talk of pressure is putting me under pressure,SC46 or SC42...OOOOOH THE PRESSURE.:brickwall:lol1:

You got em both in stock Kev.:thumb:

lol ^^^

Hi,

both sat on the shelf spooling away. :thumb:

Why not try a 42 billet if its not your cup of tea we will swap it out for a 46 billet. :D

No pressure. :norty:

cheers
Kev

Shouldn't that be the other way round? ;)

Hi,

no as we want to see an SC42 perform on a 2.0 ltr. ;)

cheers
Kev

Why not indeed,with an offer like that kev how could i refuse,will be up saturday to pick it up.:thumb:

I would have chose the 46 Glenn as I did :)

Not to scupper Kev's plans but my choice would be the 46. Proven to be a great turbo.

ya know me mate im always up for a challenge,and it will be interesting to see the results when mapped one after the other on kevs rollers when we sort out a date with him on saturday.:thumb:

go on white wagon you now you want to lol and then post up these sc42 graphs so my choice is easy : >

Kev is the twinscroll in yet?

Hi,

waiting for a big brown van with UPS written on the side. :thumb:

Should be here around 4.30PM. :D

cheers
Kev

...And they'll be spooling even more keenly in their boxes. :D

I'm sat in my van with a balaclava waiting for ups lol

:lol:

Please tell me the van come :D

No I intercepted it :-0

I hope not otherwise I'll be outside yours in the next hour :D

Lol

Hi,

it came but sadly no turbo's. :cry:

It is mainly the twin scroll turbo's we are awaiting, everything else is in stock ready to ship. :thumb:

They should be here today. :D

cheers
Kev

Restless little tubbys.

They spooled themselves out of the van when nobody was looking. :D

Patience is a virtue......but I must admit, Im eager to see what my sc46 billet twinscroll will do once the engine run-in is done:rolleyes: Lots and lots of low-down torque with any luck:norty:

Hi,

just the one twin-scroll is here. :luxhello:

Along with a sh1t load of GT30 Billets. :D:D

cheers
Kev

Cool you sending it over then tomorrow? :thumb:

Immy

I been waiting for 6 months!! Was originally waiting for the LM400 from Ian as it took them untill last week to get compressor covers in. I contacted Kev about a month and a half ago who has just come through today. However Kev made me an offer I couldn't refuse and the feed back on here is nothing but good.

Immy

Have there been any twinscrolls fitted and mapped to anyones yet, Either SC42, SC46 as i`m thinking about investing in one, Got injectors sorted, Other than that the car has:-

3 Port boost control
K & N panel filter(Might change to CAI, If req)
3" Decat throughout

Car is a MY03 STI Spec-C currently running 357bhp/358lbft with an ECUTEK map done by powerstation about 5 years ago, Obvioulsy i dont want to change too much on the car and dont really want to go front mount if i dont have to, Thinking out loud here but will i get away with the TMIC on the SC42 but probablly have to go front mount on the SC46, Any advice would be appretiated,

Many Thanks, Gaz.

Top mount should be ok up to 450bhp. My car is a JDM 2.0l twinscroll so I will let you know how I get on.

Immy

Thanks Immy,

What you going for, SC46 then?

I know a couple of guys that are running 420ish through the top mounts so figured the SC42 was fine as is but wasn`t sure when it becomes a bit of an issue,
Want to keep the Spec-C as original looking as possible so front mount at a last resort if the TMIC can`t take the 450bhp

Or stick with the SC42 and make do with just 420hp ish :D
