Hi,

we are releasing the gearbox for sale straight away at an introductory price of £2295.00 + vat for a 1st to 4th helical kit

We can offer an uprated fith for an extra £442.00 + vat

Time to start a new thread me thinks

cheers
Kev

 

quick!

 

Group buy anyone ?

 

looking forward to seeing the sc40 billet results

 

This thread is getting more and more interesting (and tempting too!)

We can all depend on Kev & co at 'The Clinic' to keep up the good work.

Continuing to watch with interest..................

 

Hi,

thank you for that

Quick update on costings and spec.........

SC36 billet.................£750.00 .(sleeve bearing)
SC40 billet.................£895.00 .(sleeve bearing)

SC46 billet.................£1295.00 .(roller bearing)
SC46 Billet twin scroll..£1295.00..(roller bearing)
SC50 billet ................£1350.00..(roller bearing)
SC54 billet.................£1425.00..(roller bearing)

Rotated Billet range (all roller bearing)

GT 30 Billet................£1125.00
GT 33 Billet................£1250.00
GT 35 Billet................£1195.00

All rotated turbo's come with ported shroud and are available with either .63 or .82 a/r housings.
We also offer Tial housings at no extra cost, clamp and flange kit extra @ £125.00.

All prices + vat.

Reason for the above is there are that many of them its getting confusing

And there are more to come.

watch this space

cheers
Kev

 

 

whats a sleave bearing turbo then?

 

I am currently building a 2.35 ej22t, i am considering going for 500hp, using the 2.35 and sti5 heads and cams, wonder what would one of these Bolt on billets be like?
What Rpm is 1bar boost seen?

 

Hi,

my car is 2.33 with an SC54 Billet direct fit turbo, graphs are on this thread somewhere but here it is again.





Boost and afr





Remember spool is considerably quicker on the road

Hope the above helps

Cheers
Kev

 

What injectors and fuel pump do you run on that Kev?

Looking at a very similar (if not identical) setup

 

Hi,

injectors are 740cc the pump is a bosch 044 fitted in tank.

Heres what it did with a methanol / V power mix







Cheers

Kev

 

o no, now need to save £1295 for a turbo
will the sc460 billet make 440 ish bhp on a 2ltr @ 1.5 bar on v-power ?

 

Hi,

The SC 46 billet should easily make 440 bhp

Cheers
Kev

 

Hey Kev, i am sorry if this is a stupid question as i dont have great experiencein reading graphs so could be wrong but is it at around 4100 rpm or 4200 that its making 1 bar on graph??

 

Hi,

its around 4150 rpm but on the road its around 3200 rpm in reality

It is very responsive

cheers
Kev

 

Hi kev
what % of methanol did you use ?
Do you use methanol mixed with a top end lubricant ?

Andy

 

Further to the point, where are you getting hold of the Meth? lol

 

I use Jennychem

Clive

 

Cheers Clive

 

Me too

 

Hi,

we add 10% generally, no lube

We also use jennychem for our methanol.

Cheers
Kev

 

Would be interesting to see spool of the sleeve bearing sc40 against the roller bearing sc46, on a 2.0, if such a direct comparison is available...

 

Hi,

they are different turbo's the SC36 billet and the SC40 billet are budget turbo's which is reflected in the price, its a big jump to the SC46 billet which is roller bearing hence the price difference.

True though spool would be interesting to compare, as are all the results, we just keep on testing.

Got an SC36 billet on a 2.0 ltr sti version 5 on the dyno at the moment, its just seen 381.9 bhp, but its a bit lean and we have maxed out the 550cc injectors and pump, further investigation required, once richened up we expect the power to stabilise at around 370 bhp which is where we intended the SC36 billet to max out,

Not bad for a budget turbo.

Keep you posted.

cheers
Kev

 

Just the same as a sleeve bearing.

A TD05 for instance has sleeve bearings, a phosphor bronze bush the main shaft runs in, along with thrust/end bearing, also phosphor bronze.
The alternative is roller bearings.
The claimed advantages of roller bearings is less drag or friction so in theory, quicker spool. In reallity, turbo design factors are probably more important.
If a roller bearing turbo goes wrong then repair is often a replacement cartridge and that can be very expensive. Repair to a sleeve bearing is relatively simple with a repair kit and providing the shaft is not scored is a comparably cheaper repair.
In my experience, a sleeve is more rugged and certainly more tolerant to antilag.

 

Hi,

sorry I missed that question, could not have answered it any better though

One thing to add for Mick who asked, the turbo fitted to his STi 8 is a VF35 and is a sleeve bearing as standard

Cheers
Kev

 

Sweet as .....
A good choice for me then ...
As it will suit my setup..
Good times

 

Hi Kev, That looks like a great result so far, should be similar for my 04 sti then. Im guessing Duncan has got my new SC36 billet I'm just waiting to hear when he can come and fit/map it for me. Would you say I should fit the 650cc injectors I have then or stick with the sti's?
cheers, Rob

 

Hi,

sti pinks are good for 380 to 420bhp depending on fuel pressure so should be fine for your application

Good luck with the fitting / mapping, hope all goes well

cheers
Kev

 

Kev, in this thread there is good talk about the use of Methanol. Looking at it a 10% mix gives a nice power increase, is it just a case of pouring the methanol in getting the ECU mapped accordingly or does anything else have to be done. Possibly a idiots guide to using Methanol could be included in this thread or a new thread before someone uses it, things go wrong and a bad post is put up.
