Post to fix bug

AlanG

I'm with Rannoch here on his comments re: his latest turbo incarnation.

I'm led to believe his is the same as is on my car which has been ran now for an adequate period of time to give truthful feedback on its' capabilities.

For some considerable period of time before i fitted the TMI-141S TD hybrid, i had given Mark what i believe to be good, accurate, honest feedback on issues with various "mix 'n' match" turbos, their problems, upsides and downsides.

Since the TMI was fitted, it has performed in all areas, well beyond expectations, and can honestly say, if you don't want the ultimate in horsepower levels but want the most useable, road friendly car with substantial horsepower and torque for relatively little boost, then this has to be high on your list of potential turbos.

It's a pity you don't stay close to me as i would have no problem in letting you experience how different the car now is with power circa 400BHP at less then 1.4 bar. It drives as well as a std car, isn't laggy and always gives you a rush when you start to *press on*.

I could take a drive one weekend to see a car like that...

Where abouts in the country are you...??

Edited to say:
Alan - just seen your 'From' in your profile...
BOTH!

How does the TMI-141S TD hybrid, compare with a TD05 FE?

EMS

Steven,

You are completely right! The state of tune is very important to the performance of the car, not only the turbo. That will be the problem to get an objective view on how a turbo performs, if you testdrive different cars with different ECU´s, exhaust systems, etc.

Mark.

Another very happy TMI-141S TD hybrid user here
I went from a MD254 (very similar to a MD304, both being sort of the same ball-park as a TD05), and the difference is very marked. Huge power by comparison, the spool-point/acheivable boost rpm being almost as low (unbelieveable for such a large turbo).
Have also found driving off-bost is much improved - the engine feels less 'bunged up' and so it's easier to drive in traffic. Maybe not much of a consideration, but I'm in London .

Glad to hear you now,eventually have a turbo you are happy with Alan. Pity it took four turbos and ten months to get there. Enjoy.

Pavlo

So you've had no turbo trouble in the time then Harvey?

DubaiNeil

Where can one find more details of this TMI turbo - such as specs, prices, providors etc?

Thanks

Paul: I have not had to try four turbos to get one that works and my turbo has been reliable throughout although I caused myself a waste gate problem as a result not tightening the housing set screws after the turbo had been fitted.
You know that anyway.

nom

DubaiNeil - AFAIK, the only current supplier of the TMI thingy is Lateral Performance, & it's likely to stay that way at a guess as it's their spec...

carlos_hiraoka

why the need of this type of comment ?

..... the thread was just starting to get back on track .....

BTW why is it that your allegedly reliable setup (IIRC you posted several times telling that you had no problems with it and how happy you were with it), after "performing" quite good for almost 10 (or more) months failed just the weekend before TOTB2 ..... I know that it was a spark plug issue, but does that mean it is pure bad luck or that something was been pushed beyond its limits ?

some people enjoy the petty bickering & constant attempts to put people down...

Gets boring reading about it day in day out - obviously have nothing better to do

Harvey,

I thought you tried a second turbo, of similar spec to your original iON part? I was only poking fun at your spanner skills anyhow.

Carlos,

Give it up man.

Cheers Paul. I was loaned another turbo while mine was sent back to Canada so my car was not off the road. I was happy to have a loan of it but it was not as good as my own turbo. I think mine is a P450 and the one loaned was an early P400.

Carlos:It has taken four turbos and ten months for Alan to get one that he is happy with. The wider audience may wish to be aware of this.I am happy for Alan it is now sorted. My comments would not exist if Alan had a satisfactory turbo in the first place. Does the truth wrankle you?

Yes the week before TOTB, after three practice starts,part of the insulator broke from the electrode on one sparking plug. As I have already said on several occassions I am/was interested in seeing how far I could take this engine and was certainly pushing it towards the limits. I am lucky the failure was a sub item and not a major engine component and the repair entailed the replacement of one cylinder head. I have learned quite a bit from what happened but think I have come to the end of the sensible development trail for this engine. A lot of what has been learned will be incorporated in the new CDB two litre which is now at short engine stage. I am hoping the new engine will prove to be reliable at 500bhp.

By the way, for what it is worth, Bob Rawle also suffered a similar but less damaging failure on one of the same plugs from the same batch.

I'm in Scotland near to the west coast.

We have got some lovely roads here, ideal for stretching the legs of an Impreza turbo, specially with its' spec at the moment ,so am 100% certain that you will have a cheshire grin and darker coloured underpants after a demonstration.....

You would be more than welcome to meet up if you are ever in the area.

Nom,

Thanks, have already been in an email conversation with Mark as the the 'appropriate' solution for my problem

Looks like the answer is in the wind

carlos_hiraoka

I have a few comments (and hopefully this will be the end of it, on my side) ..... do you look after all costumers so that they are satisfied with the products they receive, or is this only the case with Alan G ?
Obviously one is free to choose their supplier of parts, and the fact is that through the reading of boards like scoobynet or 22b people might get better feedback and make their choice.
And BTW to answer the question ".... does the truth wrankle you? .....", english is not my main language, but I think you meant RANKLE and not WRANKLE , look it up on the dictionary please ..... and NO, the truth does not rankle, anger, irritate me.

carlos_hiraoka

Thank God that a cylinder head is not considered a "major engine component" .....

Just a piece of advice, remember that spark plugs have several functions. One is to provide a spark for the combustion process to occur, another one is to act as a dielectric insulator for the ignition system, also it removes heat from the combustion chamber and finally it is used to fill the hole in the cylinder head .....

Therefore in your case the damaged spark plug may have indicated that there was too much heat present in the combustion chamber which lead to the damage of the spark plug.

OR

Like u said, it could have been just a case of a bad luck.

darkblueturbo,

if you want to easily go over 300 horses with as little lag as possible, I think that the best VFM would be a front entry TD05-16g. The IHI VF35 is a very nice turbo, it spools quicker than a VF24,28,29 and a TD05-16g, although it won't make the 350bhp that you are aiming at.

Carlos H.

darkblueturbo

Thanks for the tip Carlose - front entry TD05s seem to be well liked

Thanks AlanG - if I'm ever up that way I'll drop you an e-mail...

Out of interest, the VF35 hs been mentioned by a couple of people as spooling up quick. I test drove an STi8 yesterday and was HORRIFIRED by the amount of Turbo lag!! It made me decide to stay with my classic for now...!
But it made me think about what people have been saying on here about how much the state of tune of the rest of the car makes a difference - this was a bog standard demo car. so there'd be much less lag with 3 less cats...!

I'm going to have to wait a while on making this decision because there's a hell of a lot more to it that you'd first think...!!

carlos_hiraoka

like u said all depends on the state of tune. On an older "classic" WRX I have seen 1 bar of boost below 2700 (don't remember if this was in 4th of 5th gear, UK gearing), so definetly spools quickly.

No problem re: coming up.

Anytime suits. You'll enjoy the experience!!

Didn't see your post!!

The TMI is based on a TD05 but has an 06 compressor cover and Garrett compressor wheel.

Cheers for the info

What difference does that make to spool up and capability in general? Is one better suited to a certain application etc

AlanG

Depends on spec of car obviously (heads / cams / cubic capacity etc)but for a factory engined road car i.e unmodified, achieving a bar of boost in the low 3000's rpm results in a very tractable, enjoyable drivers car which the Impreza is and IMO should remain.

My own has 1 bar at about 3200. Could come in a bit earlier if i tried but very happy the way it is just now.

The bigger compressor/wheel on mine allows a greater airflow capability but bear in mind i also have other parts on the car to support them.

Again, IMO, there isn't a great deal of difference in spool up between the 05 and the TMI since both units use the same exhaust side. However, i only had my 05 on for 2 days and didn't really like it, so can't really comment as i didn't give it enough time to prove itself.

(* Personal opinion here*)

I felt the TD05 didn't give enough torque for my particular circumstances but that is not to say it's a bad unit. Many people are using them and very happy with their results.

iON Performance

Harvey - sorry to hear about your incident with the insulator on the plug. I guess you're looking forward to our upcoming turbo for your 2L CDB eh?

Pavlo - the loaner turbo was a P400, the one Harvey has is a P450. Depending on how Harvey's build goes, he may actually need our P650 turbo!

Alan- i gather the TMI turbo is Lateral's equivalent to Andy's TDO5/06 turbo, does it use the same compressor wheel(20G)?

i have just got my hands on a TDO5/06 from Andy for very little money and i am in the process of putting the car back together.

what was your boost target on this turbo???

oh, and how’s the skyline going

harvey

iTrader: (48)

Alan; If you are defecting to be a Skyline pilot are you selling the six cylinder block? Is it opendeck, semi or CDB?
Let us have a proress report on your new turbo when you have done a few miles and a technical assessment.
Will it make 400bhp and when are you rolling roading it???
