Hi,

run 19 & 23 for your perusal boost included





the only change between these two runs is the pipe work.

Cheers
Kev

 

Kev,

Thanks, but run 19 is FAR better than run 10, and since you have said there was no more mapping, the old fuel must have been well past it's sell by date, or run 19 ended up running more boost to gain the power

I'm sorry, but however good the GT30 billet is, (and it clearly is) the last GT30 billet/GT35 "comparisons" are flawed by both fuel, and pipework.

You have to commend Scooby Clinic for A: Doing the testing and B: more importantly being so totally open and transparent about it.
Well done guys it's good to see this as a potential customer for one of these turbo's maybe even two of them

I do however have to agree that the GT35R needs to be re tested on the new RCMS pipe work and compared with the exact same fuel that the best run on the billet 30R was done on the RCMS pipework.

Then you'll have an accurate and fair comparison.

But as I said, fantastic commendable effort from SC well done all.

 

The most open testing i have ever seen or herd of and it attracts critism?
Who else tests brand new turbo for the first time or times and posts it up?
Everyones a critic cos its easy to be one.....

 

Hi,

The GT35R wont fit the RCMS pipe work, its not the pipe work at fault its the exhaust housing on the 35R, we can make it fit but it would be a days work and then it would all have to be put back for the re-fit of the 30 Billet, we simply dont have the time for this and remember this is a customers car who is out racing soon.

Bottom line is we have addressed his original brief, better spool and more power all we need to do is the final map

The GT30 Billet is a winner you only have to look at the evo result to prove it, not only gave more power than a GT35 but spool was 800 to 1000 RPM better, if we get a car in with a 35R on it, customer willing, we will run the test again.

Cheers
Kev

Off home for a beer now

 

^^^ That's fine. At least there's a salient reason.

And as said by many, you're to be totally commended on putting your money where your mouth is and undergo these tests - for proper hard figuring, warts and all!

Brilliant stuff! Digging it.

Just gotta hope someone puts his car forward as a billet SC46 test mule, now...

 

Look, it's not easy for one supplier to go onto another suppliers thread, and question the information, and I gave it some thought before doing it, because I knew it would upset some people, and I would attract some criticism for doing it !

In no way am I questioning the the SC turbo, or the results, JUST the way they are presented. I don't even think they are being presented this way to mislead anyone, but the bottom line is, they are misleading, however unintentional.

Regardless of all the testing, I have no idea how the GT30 billet directly compares to a GT35R, and dare I say, Kev has just thrown something else into the mix, which to me makes the comparison tests meaningless.....................

To qualify, the GT30, and GT35 use the identical exhaust housing, apart from a different profile to suit the different exhaust wheels, but Kev has just said that "this" particular GT35R won't fit the same pipework.

This means that this particular GT35R is not a "standard" GT35R, but some hybrid version with a different non GT series exhaust housing !



Mark.

 

Kev you are wlcome to use mine as a test muel.35r + rcms pipework should be a fair enough test ?.

 

Ideally, the test needs to be done on a bigger engine, or at the very least a built 2.0lt, so that the GT35R can be "driven" properly. A 2.0lt will struggle to flow enough exhaust gas, especially if it's not being pushed.

 

Hi,

from the very start of the tests on this car it was clear it was not ideal, one look at the original graph shows lousy spool and power, a GT35 R on a 2.0ltr stock engine was never going to be great. I agree it needed to be done on something bigger like a built 2.0 ltr or a 2.33 ltr engine, but as this car was here for a turbo upgrade, customer requiring better spool and more power, it was time to try the 30 billet and see what it does on this less than ideal set up.

The test between the 35 R and our billet GT30 turbo was posted up using the best runs achieved on both turbo's, run 06 for the 35R and run 010 for the 30 billet, it clearly shows the 30 billet giving better spool and more power, job done, test over.

For your information the GT35 we removed has a .63 exhaust housing with a strange flange on it.

We decided there was more to come, nothing to do with the test, purely wanting to give our customer the best we can, the dodgy pipe work was swapped out and the 30 billet run again, a worthwhile improvement was shown, graph posted up purely for interest.

We have not finished yet, the up pipe used from RCMS kit is not ideal for this set up, by that statement I mean a 2.0ltr stock engine with a rotated set up, spot on if it was a built 2.0ltr, 2.1 or 2,33 aiming for 600 bhp.

As we are trying to achieve the best result for our customer we have to persevere with what we have at our disposal, we feel the up pipe could be improved and that is exactly what we are going to do next, here comes a velocity stack

All our tests are done openly and honestly, if you feel it is misleading then that is purely your opinion, I can assure you if they are in any way misleading it is not intentional.

Now back on topic

This coming week there is a new Billet turbo for testing, our SC 36 was OK but not as good as expected so we have an SC 36 BILLET to test, this is aimed at the fast road circa 360 bhp market, spool is expected to be as good as a VF34 with power around 360 bhp, it goes without saying it will be a true direct fit


Price will make you weep

The 36 BILLET will be just £750.00 + VAT

Cheers
Kev

 

Hi Kev

TBH...the 36 billet is priced very reasonable

You mentioned that the GT35 .64exh had a strange flange but at the same time managed to bolt on a Billet GT30 on the same up pipe so from what i gather they have the same flange.

But a picture will no doubt clarify things nicely

Peter

 

whats the best turbo for newage sti 2litre wanting 400-470hp on shells finest or 5percent mix cheers

 

That's quite a bracket!

But the S206 covers 400 to 500+

 

Hmm an SC36 billet, mines booked in on sat for amongst other things, a nice new tubby, was still thinking a blouch 18 or 20g, but will have to see how this billet version compares

 

Hi,

When we started this particular car, we simply power ran it for a base to work from.

The original GT35 was removed and the poor, many times repaired pipework was exposed, so was the strange flange, we decided to swap out the last bit of pipe work going up to the flange, its the shiny bit on the photo below. this allowed the fitment of our GT 30 Billet,





Note its the down pipe flange only


This done we carried on with the test, rest is history

Cheers
Kev

 

See a pic tell a 1000 words

I understand now and i know why that particular GT35 is going back on for a re test

Thanks for clarifing it all up.

Peter

 

Hi,

just to remind people how good the 30 Billet is, here is an overlay of a standard GT30 and our billet version, back to back, mapped, both runs on E 85, Morrisons finest





This car won the Scoobysprint and the Scoobyshootout 2009 with our standard GT30, wonder what it will do this year with the BILLET version

To be seen at the 30 to 130 Sunday 14 th March, watch out Clive


Cheers
Kev

 

Hi,

To keep everyone up to date here is the latest test result using our new SC46 BILLET TWIN SCROLL, Mapped.





This is a standard spec C engine, standard STI intercooler, standard headers and up pipe, only mods are induction kit, inlet pipe, full stainless exhaust, fuel pump, flow matched injectors and of course the newly re-named Syvecs ECU. All retro fitted into a classic GC8 scoob running on E 85.


This shows what can be done on a budget, turbo price £1295.00 + VAT exchange, in stock from next Friday.

cheers
Kev

 

I didn't realise the SC46 Billet was Twin Scroll?! Is there the regular exh. flange for it too?

 

Hi,
its available as a normal SC46 BILLET, and as a special in TWIN SCROLL guise for the JDM cars

SC46 BILLET single scroll not yet tested, sat here waiting for a test mule

SC46 BILLET £1295.00 +VAT

SC46 BILLET TWIN SCROLL same price but exchange as we need your old exhaust housing.

Cheers
Kev

 

Cheers - all crystal now

 

pm sent

 

Should be a close run thing I reckon, bring it on Mikee Are you attending also Kev ?

 

Hi Clive,

I am hoping to be there, my own car is being thrashed on the day, giving the SC54 Billet a run, it wont be up there with you guys but it will show (hopefully) what a direct fit Billet turbo will do

Cheers
Kev

 

Oh good, I'll be particularly interested to know how well the SC54 performs.

Top thread Kev, keep up the good work mate!

 

Def keeping my car now so bring on the turbo

 

Hi,

hot on the heals of our new BILLET SC 36 at just £750.00 ,+ vat, we have another BILLET turbo on the way

Ideal for the 400 BHP market at a budget

It's the new SC40 BILLET, ideal for the STI 7 onwards this BILLET turbo will be up to 400 BHP, at the crazy price of just £895.00 + vat.

Cheers
Kev

 

Excellent!

FTR, what's the SC36 billet good for bhp-wise, on a 2.0L, again?

 

Hi,

clue is in the numbers

SC 36 BILLET 360 bhp
SC 40 BILLET 400 bhp
SC 46 BILLET 460 bhp

etc. etc.

We always play on the low side, all our BILLET turbo's are capable of more depending on engine spec

Cheers
Kev

 

LOL, I thought you said the numbers related to the lb/min(?) flow rate of the impeller wheel, or something? ... Or is it just a happy coincidence?!
