Does anyone have a SC42 dyno graph?

it's confusing as there is a few people on here that are running 400+, even 440 has bee run on them.
as mine have the arp rod bolts surely that would make them a little bit better?
Would reducing the rpm limit save then even further? Peak power has gone by then anyway.
can you tell I'm trying to talk myself into it that they will be ok lol

Just for the earlier query Blouch and Scoobyclinic are same turbos,difference between these two is just exhaust housing Blouch using 8cm/10cm and Scoobyclinic using 7cm, they have a special deal with them which if you ask Blouch they will direct you to sc, I don't think they will make the 1 off for customers considering they do them all for sc, and I think if you did with customs charges and delivery, you wouldn't be far off sc price (they obviously get them cheaper in bulk and make their mark up like any shop.
But here's the turbos
SC50 is Blouch Dominator 3.0XT-R
SC46 is Blouch Dominator 2.5XT-R Polka Pickle
SC42 is Blouch Dominator 1.5XT-R
SC40 is Blouch 20GXT Billet
etc.

Here's what I managed to get from off here for a comparison,
From what i read they do not come with metal caged bearings standard and this is their weak point,

Cool. Thanks for the link Smurf. I recall reading that thread to be honest. It'll be Rich fitting it to the car if I get it. lol.
There are a couple of SC46 turbos floating around at the moment for £700 and just over, one looks ok, one looks horrible. Was trying to gauge the price against these as the SC42 units hardly ever come up for sale.
It's a risk I guess. At least the one you bought was essentially 0 miles after the rebuild. God knows how many miles the one is I'm looking at.

ive seen those sc46 turbos on ebay and yeah 1 looks ****ing terrible. one of them was listed on here a week or so back and look ok, i guess if you get it for around £600 then spend £500 having it upgraded/checked over then that would be better than an sc42 and if im correct you wouldnt need as much boost to make the power you want compared to an sc42.

Sort of and sort of not. I'm not trying to get 450bhp, I want somewhere over 400 in between the two. The SC46 is overkill for that level and will take more to spin up compared to its smaller brother SC42 unit. Therefore for my level the SC42 billet would certainly give less lag and be a generally better option in my opinion.

1k is decent price for 42 aslong as its the newer black housing/front.
both mine have sold for 1350 is tip top low mileage condition.
an sc42 is better that a 46 in the spool and drivability department.
46 barley make 460 tbh only good speced cars, loads of 42s have gone over 420 though.
i know which one id go for.,..

and the bad caged bearing problems is more than likely on the older units also. I haven't seen or hard of a faulty black housing one failing or breaking.
for the power band of 400-450 I think the sc42 is probably the best drivable turbo out there bar non. Probably why I've had 2 and swear by the drivability of them. On/off throttle is excellent on them too.
I might get another

if going for power the gt30 0.63 billet is a great unit for outright power and spool.

depending how you want your car to drive, both them turbos are no comparison on the drivability of the 42! But PT and md321v will obviously make more power. But power is nothing without drivability, so you need to decide on power output and how you want car to drive and what's more important.

must be a lot more than a couple of years old then, the black front ones have been out for a good few years now.

Out of interest have you experience of other turbos to back up your statement above? Genuine question.

My SC42 which has been tinkered with showed 487bhp on Andy Forrests guestimator with 30% Ethanol & 466bhp with 20%
was 427bhp with v-power alone
Graphs are on my thread cam post 2moro.

I believe the rebuilt one i bought failed due to sooking in debris so i cant blame the bearings on that one.
Still see some black housed ones being posted as having upgraded to metal cages in similar way mine was so cant be that way stock i would assume.
Wish i had tried mine before got sent away to see what difference it made

ive compared it to a precision (mate had one and a bit laggy for a point to point), mdx555 400 one (was the older version and tbh didn't seem to feel quick), md321h (again the older one and didn't feel exciting), I prefer the sc42 for the best all rounder as said above.
the sc42 seems angry when on boost and actually makes you grin so to speak. So just my opinion for that hp figure I'd choose it again without a doubt.
show me another turbo in that hp area.
Blouch still make both housings to be fair so cant see that playing a part.

tbf I haven't really heard of the bearing issue to be that common apart from the odd folk saying it, and if it was an issue I'd of thought it would of been revised no? Driving on wot and then just switching engine off could be a culprit for that, but then that's down to driver.

scoobyclinic really, I think they have a stock issue from supplier, best bet is to phone them and ask.

All the 'new' ones I've seen including the 36 all have the black front on, so I'm assuming it's a revised/ironed out one (remember the old 46 that have a design fault on the exhaust housing and used to crack? But then later that was redesigned hot side).

again I havnt seen a ‘sc42’ have the issue.
and if garret still use the plastic caged bearings then im sure there is no problem with them, but either high temps, stuff getting in, incorrect cooling for turbo, lack of oil circulation etc etc, it cant be a high percentage of issues or garret would of addressed it as garret are not a small brand with low sales figures.
and I believe its a nylon not plastic, dont under estimate the strength of nylon, infact a lot of turbos have a nylon carrier including the precision I believe.
dont get sucked in by 1 mans problems. When it becomes common then i can relate and agree and infact help you slate them lol.
