I think you have the water fitting fitted wrong.
Have a look and try but I think that is the top fitted to header tank, not the the head fitting. Not fitted an lm myself but just how it looks from pics.

Not sure what the issue is with the oil pipe looks fine?

Does this help?

johnny_0

Absolute yes! Problems has been solved! Really many thks to you Tim and Jolly for your fast reply. Now we have swap the two turbo's water pipes and all is fine.

Thks again

Cool

Did the first mapping session today, and wow does it pull now
I can feel a little loss on low rpm, but from mid up it defo puts a smile on my face.
Will try to dyne it in the near future

Is the difference night and day......?

The charicteristics of this turbo sound more and more like the VF42 rollerbearing turbo which is already on my car. However When I had an S204 mapped by JGM there was no difference in power or torque due to the injectors maxing out. This has got me thinking that it might be worth me just investing in a set of injectors first get a map done and see how I get on untill the LM400 arrives.
See if I can get 380bhp/380ltb+ will most likely get Graham AKA Engine mapper to map the car on open source and see how we get on.

to answer this question I need to drive it a bit more, I did only 15 mins on the way home back from the garage, we will try to improve the map tomorrow and then i got the weekend to have some fun and see what this turbo is all about

Immy,
No difference in power / torque due to injectors maxing out? I don't understand..... what did you have in injector wise... 380cc ones! roflol

Seriously though, no difference in power from what figure?

Ilya,
From the before and after comparisons I did and the data I have, the Billet provided the same power / torque to just under 3k and then pulled away from the VF.



Different mappers do "it" differently and mine does run a fair old chunk of ignition in favour of smashing the **** out of the duty cycle and going for outright boost, whereas I know others may favour boost more than ignition. It certainly makes for a "brighter" response and stronger mid-range, the way mine has been mapped. I have driven my car with a map that did not run as much ignition, but more boost and it was as flat as a witches tit in comparison.

They were the standard S204/STI/SPEC C injectors. Spent £2000 on an exhaust filter and remap only to get the same result
It didn't feel any different ,was louder due to the exhaust but that was about it.
Put both cars on the RR back to back both cars were more or less identical think 2BHP more and 5ltb. Was told that the standard injectors maxed out so couldn't get any more out of it. It was mapped for 98 ron so that might of been a factor.

The injectors werent maxxed.. main problem with that one Immy was the person between us.. the trader talking to you and taking your money and getting me to map it..

it was tailored down a little due to I was told at the time 97ron at best as was going to Ireland? the road dyno plots showed a gain.. unfortunatly also the RR you used had an issue with said trader and a big history which I also dont think helped lol...

I'll see if I can find the road dyno plots.. goodness knows how many years ago that was
Also I remember now I reloaded the original map and someone drove it (was it you or owner?) and then reloaded my map so with the louder exhaust and the difference was very noticable.

I took out two 320R & 370 and both survived

I've sold the LM400 Turbo someone got a bargain IMHO

Although it's not an LM series twin scroll this is where i am at the moment with my LM 500 single entry.

Power is a bit on the low side for the size of the turbo but it feels strong on the road,which is what it's all about for me.

Looking into ways of upping the power in the future without affecting drivability or creating excessive lag. All advise welcome on this.

Am pretty sure I remember you telling me the injectors were maxed out.Yes it was 97 ron ,but at that time the best fuel was 98 ron optimax.

I've just tried to find the thread ,but the search doesn't go back more then three months.


Was his name Graham at TSL? he did say the fuel you used was four weeks old and that would of had an impact on the results.
However when I took it to the RR both cars were filled up on optimax at the time 98 ron. Not sure of the relationship between them tbh was it that bad?

Have you mapped any VF42 rollerbearing turbo's since if so what have you had out of them?

Immy

Shaun

Tony,
lol

Dave,
What did Rich say about it? TBH it's not running a shedload of boost.

What's the full spec of the engine and ancillaries?

Immy,
Four week old pump fuel won't cause ****...... unless it was left in an open bucket in the back garden! lol

I dunno mate

Am not up to scratch on the ins and outs like you although I should be
I guess am going to have to splash the cash on a project to learn half the sh#t you know!!!

Rich said the tgv's need deleting, i assumed they were during the build but obviously not !

Boost is a bit low i agree, not sure if it's related to the above or not though.

Basic engine spec is :

K1 rods
Cosworth pistons ( higher cr than std i believe )
Bosch 720
Blitz FMIC
Wing mounted induction
Tractive manifolds / up pipe / exhaust

Hi,

I own a GruppeM induction kit. And my mechanic is installing it with the LM turbo.



The question is, for higher cool air flow (1) is better run a pipe / tube from the front bumper area into the fender (and so remove the stock resonator in the fender) or (2) no pipe and so the resonator can stay?

What is in your opinion the best choice (1), (2) or other advice?

thks

Got to wait untill the end of the Month..............turbo dynamics need to pull there finger out. Feel a bit for Ian as he's stuck in the middle

Think I am just going to go down the SC/Blouch route. Looked at the graphs the other day and was very impressed.

Immy

johnny_0

Before (old Vf36 setup):



Now (LM450):



About previous question i choised the first solution. So removed the resonator and put a pipe from bumper for cold air.

Shaun

Johnny,
Will be interested in your results based on your set-up!

johnny_0

Sure after mapping

Have any of you guys used the 76mm (3 inch) ported intake/inlet? Any issues with fitment? I'm running a EJ207 and was wondering what problems I would run into. I've heard using the 3 inch inlet pipe and 3 inch turbo is a pain to install, but my manifold is off so that should make things easier.

Anders_WR1

iTrader: (8)

I read somewhere on here that a 3" inlet on 2l can result in surge. Not sure if that applies to twin scroll but as they spool quicker I recon it's more likely to induce surge.

Anders

Deadpool

I dunno about that, I've never heard of anyone having issues with the 3" apart from the install, many claim a little better spool up etc.

Anders_WR1

iTrader: (8)

Isn't that the issue though, a large turbo spooling very quickly low down in the rev range on a small engine, the engine can't consume the air quick enough and turbo surges.

Deadpool

Never heard of that issue at all, many people switch to rotated mounts to increase spool on the much larger turbos.
