here you go, hawkeye wrx, forged 2.5, sc46, sti inlet manifold, perrin intake pipe, wing mounted induction kit, scr race decat, 700cc injectors and a walbrough 400lph fuel pump. Have got an sti top mount and maxed it out.

o also what was the spec of the build, did you get the rods doen as well as the pistons?

LOL! I take it you've gone FMIC since then Tidgy? What did it make?

no mate, still running as is. not bad result though considering it out spools my old classic running a vf34 lol

:D - surprised you didn't just go for a '42, but I suppose with the '46 the extra is already there if you want to go FMIC. Bet it still flies though.
I just enjoy the SC42's ability to keep going psychotically when you floor it, but combined with a larger capacity engine I bet the combination's bang on.

It's tempting to go 2.5 or even 2.35 but I just can't justify the cost (and can't afford the fuel I'd use!) :(

will eventualy get front mount, syvecs etcs just waiting for budget to recover a bit first lol

tbh i find mine better than my old 528 bmw, hitting high 20's mpg

I got the rods fitted.

Went to andyf yesterday and was sent home because the 20g in the car was a copy.

I want to keep the oem look so hence why staying with sti topmount and oem Sti injectors.

It's just going to be a quick road car.

Would love the sc42.

Bye that's a nice graph tidgy.

What is it like for road use?

if your looking at high 300's then i would consider a front mount mate, black to hide it a bit if you want ;) but the top mount gets mega heat soak.

Its great, power delivery comes in very smooth so not having to rev the crap out of it to get it going. 2.5 is def the way to go :)

Yup i agree the forged 2.5 does make a nice easy driving road car,its just a shame that your limited to how much power/torque you can put reliably through them,and for some:norty:,450/470 just aint enough im affraid.:nono::thumb:

lol, i lit all 4 wheels up last week so even at 400 its not useable all the time :P lol

does get mega expensive beyond that though :(

:cuckoo:


"Power tends to corrupt, and absolute power corrupts absolutely..." ;)

:lol1:

HELL YEAH :banana:

Any comparisons of sc gt35r 1/2 to the new version 3? thanks

What he said! :thumb:

Fully forged 2.5 here with an SC46 FMIC and other supporting mods. Out spools my old 340bhp VF35 classic, but has 470/480 bhp/lbs at just 1.7bar IIRC

Real benefit of 2.5 is response, torque and boost threshold.

I'd argue that for the road and providing you don't want to go over 500 bhp 2.5 with SC46 very hard to beat.

If you have 2.5 the SC46 is a bit of a no-brainer! :thumb:

I love the SC46- I think its the best turbo for spooltime and power delivery on a 20% whiff of meth my car produced the graphs you see here after Bob Rawle mapped it. BEAR IN MIND as its a 2.5 we had to limit boost t0 1.7bar so this old snail had MUCH more air to give its just the 2.5 SCDB and wandering headgaskets that stopped it.

523ft/lbs of torque at 4500ish rpm!!

fantastic device and highly recommended.

This is an API built 2.5 forged motor on V5 heads with a Front mount, Alkatek Ecu, and 850cc injectors mapped by bob rawle.

it runs 1.7bar but having just done a headgasket at Castle Combe I would echo he sentiments on this thread.

They drive brilliantly and have sledgehammer midrange but you just cant get the things Strong.

I am dropping the boost from this level back to a more sensible 1.4bar so should still make 420ish HP

Will let you know.

2.5 will let go at 500 most times so stay below that and should be fine. 450/460 bhp and then what ever torque it makes will make for a ballistic road car anyway

Been on the lookout for a sc38, is the web price set in stone or is there any movement for SN members ?..
Looking to buy asap ..

Cheers

I have a built 2.5 fully forged and probably goin sc46 twin scroll,be interesting to see how that behave`s

It behaves very nicely.....:D

Its always best to go and see kev face to face mate,but if you cant get to the clinic drop him a pm on here or email him with what your after.:thumb:

Hi,

I dont always see PM's, please E mail direct on info@scoobyclinic.com

Cheers
Kev

re sc50
 

Hi is there a graph of a sc50 on a 2.1 with meth ? cheers gary

Hi Kev,

I have a 2.1 CDB+Big port AVCS heads (exhaust ported) with Lateral FMIC and RCM Header + syvecs
I'm wondering if it's possible to clock the compressor of SC46 of 180° ? what about the wastegate bracket ?
The aim is to shorter the pipe length and I'll save some space between engine and firewall.

Thanks

Hi,

they can be clocked if you grind off the tiny locating tab on the core, you can then move it round, wastegate bracket however is a different matter and a custom one will need fabricating.

Cheers
Kev

We clocked my sc46 for shorter pipe work :) works brilliantly pole position done it

Thanks. Any pics of clocked SC46 ?

Latest Billet 35R results.
Red trace was from when the car was a Syvecs tuned JDM Hawkeye with decat, front mount and air filter, blue trace fitted with an Enginetuner 2.3 with all the goodies, Tesco 99 fuel and 2 bar boost.

Very nice graph martyn and great early spool for such a big blower,even on a 2.3,well done top result.:thumb:
