This is turbo porn at its best !!! :norty: i will be back in the fold one day & have a great idea for my next Blues Brothers car back in the uk :idea: can you guess what it will be :norty:
Keep up the great work guys !!!!!

KEV when you get time could you post up the graphs for the sc54 and the GT30 billet so can compare spool/peak bhp please and i take it both turbos where tested on your car cheers knibby

Hi,

the tests were done on two different cars both running 2.33 engines and on a 20% meth mix, my car (C6 SUB) has DH22 profile cams and ST! 4 heads (ported) running the SC54 direct fit Billet turbo, the other car has standard STI 8 heads and cams with the advantage of avics, and a GT30 Billet, both run the amazing Syvecs ECU. :thumb:

The above graph shows two traces one in red is the standard GT30 the blue trace is the GT30 billet. :)

The car I referred to earlier with a GT30 billet that made a bar of boost at 3100 RPM and 1.8 bar at 3600 RPM on the road is also a 2.33 but with totally different spec regarding heads and supporting mods. :D

hope the above helps with your enquiry.

cheers
Kev

Thats one steep curve!!!

Can you get a existing gt35r upgraded with the xtr wheel?

Has anyone tried an SC54 on a built 2.5 yet to your knowledge Kev ?
I reckon it would be an awesome combo on a car with dual AVCS.
We have a hatch on the dyno at the moment fitted with the astounding SC46 Billet. With just 5 litres of meth (Not even 10%) mixed with Tesco 99 and 1.5 bar boost we are seeing 491bhp and 480lbft. Going to wind in a bit more boost this morning and see if we can break 500/500.

Martyn

I'm hoping that is on a built engine Martyn :)

Nice figures !

Finishing off an SC46 billet on the dyno this lunchtime too on a 2.0L though - should be interesting.

All finished, 510lbft made at 1.7 bar peak boost and 494.4bhp at 1.5 bar top end.
Racerom patches applied inc downshift autoblip, launch control, per gear boost control tweaked and switchable maps sorted.

Martyn

OMG Kev Cant believe your car is pushing out this much power now :norty: How does the dog feel about it sitting in the back :eek:
Great results dude !!!

Martyn, is that SC46 a single or twin?

Its single

Lets see my graph Martyn :notworthy

Your wish is my command, lol.

Awesome doesn't describe it on the road.

Looks mega!
Really wasnt expecting it to gain so much from the meth.
Cant wait to pick her up now.
See you tomorrow :)

^^ Impressive - what's the spec fella?

TX.

Hi,

nice one fellas, just look at that spool and it will be around 1000RPM earlier on the road, that must be mega. :D:D

Cheers
Kev

Currently running in a forged 2.5 set up with a SC46.......it's torture, can't wait till Bob applies the final map! :D :D

How long do you think it will be before Bob does the final map? There are others watching with interest you know!:norty:

Enginetuner built forged 2.5 motor, stock heads and cams, SC46 billet turbo, Perrin induction hose, AEM CAIK, Cosworth front mount, Helix clutch, fuel system inc underbonnet swirl pot and Bosch 044 external pump, Ecutek 800cc injectors, full 3 inch decat exhaust system, RCM wrapped headers and uppipe, 3 port boost control solenoid, Ecutek Racerom remap @ Enginetuner.

March 12th! :D

hello?

Hi,

sorry I have not got back to you I missed your query amongst a flurry of posts. ;)

In answer to you question, yes we can get the turbo cleaned up, checked over and a billet wheel fitted and balanced for £350.00 + vat. :thumb:

cheers
Kev

I am searching for a turbo that will produce a higher power output for improved elasticity datas at middle and high revs.

The turbo should also have a good spooling response, not much worse than VF35.

Here's my current performance diagram:

http://h-4.abload.de/img/gp_tuning_wrx_sti_my03ooah.jpg

Setup:

-2003 blob-eye type uk
-ej20
-standard internals
-standard tmic
-3" turbo-back
-Bailey Motorsport DV12
-Ecutek
-Green Performance panel filter
-Walbro 255 fuel pump
-VF35 turbo
-98 octane fuel

Which one you would recommend me, when I don't want to change my tmic setup?

By now my car gets only 102 octane fuel :)

A SC40 billet with sleeve bearing or a SC46 with ball bearing?

I think that the SC36 or SC38 won't perform much better than my actual VF35 setup.

What would be the right turbo for my requirements, the SC46 sounds very good and which injectors could you recommend me, 650cc ones?

SC46 is great on 2 litre Sti engines too.

One of our recent 2005 UK Sti customers said this "it went on to amaze me the shear acceleration lol and couldn't believe how responsive the sc46 is....it felt quicker response wise and as quick if not quicker to spool as my vf35"

Full details here.

And speak of the devil ay martyn lol yes that sc46 with the supporting mods (thread above) is awsome, as i have said before it spools the same if not better than my vf35 and thats with the perrin fmic on instead of the sti top mount aswell :) its happy days......

any billet wheel or xt-r wheel?

Hi,

we only do the XTR billet wheel. :thumb:

We have developed them and the range of turbo's to suit over the last 2 years with Blouch turbo's , as you can see from the size of this thread how much testing and development work has been carried out, in the end it was well worth it. :D

cheers
Kev

Hi,

somewhere on this forum its been claimed that billet wheels are in fact heavier than their standard counterparts. :wonder:

here are the results of a weigh in to of our wheels proving otherwise. :thumb:

18 G....standard 71g billet 48g
20 G....standard 72g billet 49g
35 R....Standard 120g billet 83g
37 R....Standard 132g billet 86g

They look considerably lighter to me. :D

Cheers
Kev

On average, going by the above ^^^, the billet impellers are pretty much 33% lighter than their regular counterparts. Whooooosh! lol :cool:

I've been told that a billet wheel improves part-throttle spool very noticeably, but that WOT spool is worse. Not sure I understand why this should be?

Hi,

billet GT30 versus non billet GT30. :D

Red trace non billet, blue trace Billet. :thumb:
