confused now.... so whats best turbo for a 2l sti 8 again and can this car have a twisted set up ie gt30 or is this too laggy
mick again lol

Awesome results Kev, what is the spec of the motor on this paticular car again ?

Seriously impressive figures!! :eek: Not that there was any doubt, but that's my turbo sorted for next year's track car :thumb:

Very impressive ! What heads are on the 22b ?

Clive

No you didn't :lol1:

Be rude not to ;)

No offence, That's all fine and dandy, but 90% of us dont want a 550 - 600 BHP road car :cuckoo: how's about you do some tests on something smaller, Something around the 400-450 maybe even as high as 500 BHP on a 2.0L, 2.1L 2.5L, would be nice :)

Couldn't agree more :D

Some of us do though guys

Ok, so those who can afford it are interested :D

My missus is likely to give me a good hiding if i went over 500.

Until i can get her intoxicated enough to agree to over 500 i'm going to have to stick to 450 mark. :p

Which most of us can't :lol1:

With events like scoobysprint getting popular im sure loads of people will be looking for a turbo which will offer quick spool up & decent numbers rather than out right mahoosive power, I know i am :)

Think thats why they making these turbos though so they can get big bhp but with quick spool up. because when i looked at the power graph spool looks very low down the revs ... dont it?

Not low enough for something very tight and twisty IMO, not on a 2.0 or 2.1 anyway :)

Maybe it'll be a near impossible task but i'm waiting for the day a 450-500 hp turbo that primarily suited for a 2.0ltr to be made. Obviously still retaining suitable spool with all that grunt.

Perhaps i'm just too demanding lol

They do do turbos for 400 hp too guys and they have made these better too with the billet compressor wheels as well.
I think they have tested the bigger power turbos because its one of there cars that they are testing on and it had the older turbo on it so simple to swap and get a comparasine? im only guessing but makes sence

The sc46 turbo is what your after then mate as i went there saturday and this turbo is mint as it is suited to my sti8 2l and would make 420-480
They are all high quality units i just really wanted 500 plus so either 50 or the gt twisted for me hopefully but thats on a 2.1 stroker which adds a bit but the stroker they are doing is bloody too cheep to miss should be quite a change

I havent seen any graphs or testing done with one, How does it spool on a 2.0L, 2.1L does it spool faster than a 321H or a 20G for that matter?, Theres just not enough info on this to make me want too buy one TBH, hence why i was asking about some testing on smaller turbos :)

All impressive guys, are these units roller bearing or journal bearing units?

Impressive results :thumb:

Will be interesting to see how mine compares once I finally get it on the rollers.

Hi,

Lots to answer there, I will attempt to answer everyone in this one post so as not to be accused of bumping the thread back to the top. :)

To answer Martyns question spec on the 22B engine is as follows........

2.33 ltr with one of our stroker kits
Original 22B heads, ported in house
DH 22 profile camshafts
Hyper flow FMIC
SC 54 Billet direct fit turbo
Modified K&N typhoon cold air induction kit.

R A Dunk,

I agree, here at the clinic we do everything from simple service work through to major power builds and track cars, our main core of customers are Subaru owners that want more power but not the big figures we have listed here.

Working with the big power stuff allows us artistic license to try things, such as the billet wheels being tested in this thread, some things we try simply don’t work, for example we are trying for a turbo with quick spool that will give a nice 380 bhp (approx), it needs to be consistent and reasonably priced, the first two samples made to our spec were no better than a VF34, so back to the drawing board.

Our SC46 is a Garratt cored roller bearing turbo which flows 46 llb's of air, it works great on 2.0 ltr cars and is the mainstay of our STI 2001 onward's 2.0ltr tuning package, far superior to the 20G turbo's it always gives us over 400 bhp and quick spool, in fact another well known tuner described the package as "insane" stating it was the best 2.0ltr modified package he had ever drove.

Not wishing to rest on our laurels we are now having the same design billet wheel made for our SC 46, if the results on the other billet wheels are anything to go by this should be a winner, watch this space :thumb:

WRX 9181,

The SC46 figures you quoted are a little bit out, the current SC 46 will flow 46 llb's of air, we generally see 400 to maybe 415bhp on 2.0ltr cars with avic's and relevant supporting mods, on 2.5 stuff we see up to 450 bhp, the billet version should achieve the figures you mention, ;)

Thanks for the interest shown in this thread, today we are testing the SC50 back to back with the SC50 billet, results to follow.

Cheers
Kev

Hi Kev, I already have a GT30R but wanted to know if it possible to have one of your billet compressor wheels fitted to it?

Banny

Good feedback kev,

So im guessing that all of the SC series are roller bearing units?

I only ask this as its a good indicator as to how they compare with price on the MD series turbos. The MDs have been the benchmark in recent years, and while competitors will say their turbos match the power of the MDs for less cost. This is often due to the less expensive thurst bearing cores.

Most people only see the price and dont look into the quality of the core etc when buying a turbo.

Cheers for the feedback, looking forward to more results :)

Hi Banny, I will ask the question.
cheers
Kev

Hi,

all our SC range are Garratt cored, roller bearing units, the latest billet ones also have a custom cast exhaust housing , see photo's, some turbo's out there simply have extensions welded on to accept the core.

True the MD series have been a bench mark turbo, in fact my 22B had the original development MD321 T on it for years, it got replaced with our SC46, then an SC50 and finally an SC54, now replaced with our SC54 billet.

We have seen many long faces when mapping on our dyno due to poor quality turbochargers, it is false economy and you are right to point out people need to look at this and not just buy on price, buy on results, quality and back up :thumb:

Cheers
Kev

Same engine and cams as mine. Only 30 bhp behind my 35R ! I am seriously impressed.

Kev,

Have you tested one of the billet 35R's as yet ?

Bring it on. :) and don't forget to log these hector pascals. ;)

Hi,

Not yet, in fact we are swapping out a 35R for a 30R billet to gain spool on our LMA winning car, seen here in action :D


Attachment 53188


Will let you know when the 35 R billet arrives for testing.

cheers
Kev

Thanks Kev, will be interesting to see how the billet 35R compares to results others have had on a 35/42R, given some of your initial results there may be an argument to go with the 35R billet over a 35/42R. That's assuming you get a smilar percentage increases compared to others you have tested so far. Could therefore be the next step up for myself :)

What did the 35R make on your LMA car btw and on what engine was it?

Hi,

it is another 2.33 ltr with version one RA heads ported in house, DH22 profile camshafts and a Solaris ecu, made 580 bhp on V power.
This engine was built early 2006 and has raced for 3 years taking many trophies on the way. :thumb:

We will back to back the turbo's as soon as possable, re-runing the car with its GT35 R first to see what effect 3 years of racing has had on the engine.

Cheers
Kev

Impressive, 3 years of hard work and still winning. Well done !

Look forward to seeing your test results, I myself am resisting temptation to go bigger than the 35R, and your new billet version may be the ideal compromise :) If you decide you need another test motor give me a shout :)

Hay get in line mad hammer lmfho
