I`ve heard on the grapevine the new GT30 billet R produced the goods yesterday at santa pod,seems these turbo`s of yours are unstoppable Kev,well done mate.

 

Pmsl classic

 

Hi,

Not looked at the thread since Saturday, its gained a number of pages and loads of questions to answer, I will try to pick up a few here, if I miss your question fire it at me again please.

yes Santa pod worked out OK.

Piloted by Mikee our drag car ran a 9.48 standing 1/4 with a terminal speed of 152 MPH, which gave us 2nd place on the day and 2nd overall in the championship, not bad to say we missed 3 rounds.

Alan, we are still testing the 30 Billet + wheel so its not yet available I am afraid.

Friday was a great day with some great results for everyone, didn't realise that a regular poster and billet turbo supporter was on site, Joz, nice to meet you.

craigyp ....

We will always have a deal on swapping out a turbo if you feel that you made the wrong choice, all we have to do is cover the labour at cost, the main restraint is usually time.

If I have missed anyones question please either PM me or post it up again.

many thanks

cheers
Kev

 

Kev what turbo would you say would be best for a Blob STi UK with just full 3" decat and panel filter. Want as much as I can get out of it without having to go for a rebuild. Car has done around 75k but is running fine.

Cheers

 

One is a true twin scroll the other isn't.

 

Kev,
Congrates to "The Team" for the weekend result.... stunning for the spec.

Einstein RA,
This is like pulling teeth!

Just because one is using a twin scroll system as opposed to a twin entry system doesn't make it better as a matter of just that.

One has a purpose cast housing and the other one uses the OE housing.

One has a housing designed from the ground up and the other uses a machined OE housing.

One will use a core specification that I will bet my last £1 on, is a different specification to that of the other.

There is more to a turbo than just the housing internal volute configuration.

I'm not saying which one is better and unless you tested them back to back on the same vehicle, you won't be able to suggest that either.

 

Hi,

we find these cars work well up to and around 400BHP, to get there is a long road though.

copied below is a little write up we did regarding tuning the STI, this is what we send for peoples perusal when looking at tuning....


"The 01 to 06 2.0ltr STI vehicles tune easily up to 330bhp on decent fuel such as Shell “V” power. Based on our performance pack 1, exhaust, fuel pump, cold air induction kit and a re-map they will usually achieve this figure, however the next steps start to get expensive, bhp per buck becomes less and less value for money, end result, however, is stunning .


The next step towards the 400 bhp goal is a replacement turbocharger, add something like our SC46 roller bearing, direct fit billet turbo, an up rated inlet pipe and fuel regulator you will see around 375 BHP, this tops out the intercooler, the next upgrade would be a FMIC, this allows us to run a little more power and we see around 385bhp, as you can see the gains per mod are getting smaller as the cost spiral ever upwards.


At this point a decision is needed regarding the engine management, standard management cannot see safely over 1.55 bar of boost and to achieve our magic 420 +bhp we need to run higher boost pressures and better boost control,.
The standard management is air flow meter based and not really suitable for big power applications, we recommend a Syvecs speed density ecu, this unit does not run an air flow meter and comes with free anti lag and launch control as standard. If we now take a step backwards to the original power pack we see that an ecu re-map costs £550.00, if we add the Syvecs at this point we save money in the long run, syvecs ecu’s cost just £1695.00, fitted and mapped, less the £550.00 ecutec map, it actually future proofs your car ready for the big power upgrades discussed here.


With the addition of the new ecu and a set of fuel injectors your car will see 420bhp. A long and fairly expensive road but the end result is stunning, the package has been described by another well known, award winning tuner as “insane”
You will need on top of our performance pack 1 the following…………….




SC46 Billet turbo,

Up rated inlet pipe,
Fuel regulator with fitting’s,

FMIC,

Syvecs ecu, fitted and mapped,
Fuel injectors (flow matched)"


The above discusses the use of the SC46 Billet, now we have the SC42 Billet it would be a better choice for the above package.


Hope we have not raised more questions than answers


cheers
Kev

 

I thought standard ecu was good for 400+????

 

For that year of car the UK ECU can't "see" boost over 1.55bar, so unless you had a much bigger turbo you would be limited for safety reasons, against what turbo could make what power at that maximum boost.

You can of course run more boost than 1.55bar, but you lose some of the safety features.

The JDM ECU with the MegaROM ROM coding can see and monitor above this 1.55bar limit, but the poster mentioned his car was UK so hence Kev's response.

 

It can do with the right setup, Its the boost threshold on the ECU that is the issue as far as i know as you cant see whats going on above a certain level, IIRC,

Gaz.

Edited to say i was too slow, But is as i thought.

 

Thats a bit like sticking your head into the lions mouth and seeing if it bits or not

 

Here's the video I took of Mikee's PB. Congrats to the Clinic and Mikee, my new target is 9.47

Let me put it another way. Would you agree that the coil spring and damper suspension is a more advanced system than say a leaf spring set up?
As for testing back to back, watch this space.

 

So basically you have no idea, so you thought you would provide a totally unrelated and meaningless comparison with suspension!

However, I do look forward to your back to back tests.

 

The metaphor went over your head.
I am a man of few words. Abraham Lincoln once said 'it is better to remain silent and be thought a fool than to open your mouth and remove all doubt'.
I will say there is 'some' difference between twin entry and twin scroll.

 

I see where Einstein RA is coming from hence my choice for the twinscroll setup not to mention the price difference. We are just assuming that the twinscroll will be a better setup ............why because it's twinscroll

I understand where Shaun is coming from as again it all depends on the spec of the turbo however I can't see there being much in it between the two. In "theory" I expect my SC to spool up quicker due to the fact that it's twinscroll and given that they both share similar components garett cores and billets wheels.

Shaun has hit the nail on the head and the only real way to find out is a back to back on the same car and setup.
Would be interesting to see this done and would love to be there when it happens

What would also be an interesting comparison is an SC turbo with the twinscroll housing against an SC turbo with the Lichfield housing.

It's a shame it's taken me so bloody long to get mine sorted otherwise we would of had some results by now.

 

Shawn, what about RACEROM on the uk cars? My Sc46 is mapped to 1.7 bar by Bob and he didn't mention anything about ECU limitations.

 

Immy,
The price difference is £50 on a like for like comparison I thought.

Assumption is the mother of all **** ups. I know as I have had triplets on many occasion.

Anyway.... forget all this, just get your turbo on and mapped. As I have said, I'm sure you will be mega impressed with the outcome of your SC.

Will be good to hear your feedback.

NS04,
Yes you're right afaik, but the guy asking about his set-up was on a MY03. Hence my "For that year of car the UK ECU......"

 

My bad on the price

Will get results up at the end of the week, but after hearing you bang on about Ecutek and racerom you've got me thinking about getting ecutek'd.
I had the Ecutek software and dongle with 4 or 5 licenses which I lost and Ecutek wanted to charge me another 4k to bloody buy another one so for that reason I've boycotted Ecutek

Immy

 

If you bought a car and then lost it you wouldnt expect a free replacement unless insured would you

 

I like your annotation Simon. ROTFL.

If you are staying with the MAF Sensor do not write off Race-Rom until you have experienced it in action. Includes downshift blip and flat shift if you like that sort of thing.

 

agreed it is very good but only an option on the 2.5 hawk / hatch etc, ie. not a twin scroll.

 

Perhaps if the car could be remotely disabled and rendered completely useless and didn't cost the best part of £5 it would be an half decent comparison

All they had to do is send me a dongle instead of trying to have my pants down

immy

 

Litchfield offer it on the hawk and hatch twinscroll........Shaun has it on his car which is also a twinscroll hawk

 

it cant be remotely disabled.. there is a yearly update date which it could be removed from the database so it wasnt possible to update it and it would stop working after that date.
I wore mine out and they exchanged it for a new one.. but I guess no point arguing over it.

Simon

 

Thats mighty good of them ,but I guess it's in there best interesting to keep you happy with the amount of business your pushing there way

Immy

 

You're getting confused.

I have MegaROM not RaceROM. Both by EcuTEK, but the RaceROM is the updated version of MegaROM. I can't utilise RaceROM on my ECU, which is a shame.

So it goes (being very simplistic):

EcuTEK - All mappable cars
EcuTEK MegaROM - Only JDM Newage STI's from MY03-MY05 (better than standard EcuTEK)
EcuTek RaceROM - All mappable cars from MY06> (better than MegaROM)

 

I expect if I lost it, it would have been the same situation Immy.. I meant I handed them my old one and got a new one.

I digress anyway

 

Cheers Shaun you make it easy for simpletons like me
