Has anyone else had the ceramic coating flake of their turbo I have the LM420 and about 30% of the zircotic coating has come away > mine is 9 months old.

Lee.

 

Thats quite shocking considering the cost...

 

It would'nt surprise me to be honest as it happens to a lot of products including downpipes and manifolds. It won't stop me from buying mine

Immy

 

wonderfull !
Iain answered me, the worry is that we need a 2.5 " cover in the EUDM !
phew!

 

Is it the turbo inlet pipe you're talking about? If so I guess you have the wrong turbo version. Is Iain exchanging it for you?

Alternatively, you could look for a Spec C or JDM STi inlet manifold perhaps?

 

yes, i have the 3" and it needs the 2.5" !
it needs a custom 60mm compressor cover for EUDM.

 

Not trying to be an a$$, but I think the oem turbo inlet size is actually more like 2.4 inch (61mm) and the inlet at the compressor housing is like 2.3 inch (58mm) Somebody correct me if I am wrong.

 

As promised but late my LM400 RR graph

Mine car was very first on rollers on an "EVO" RR day. He only did speed set up and only one run as it got 404bhp so he didn't bother doing ought else.

A few evos after, had silly bhp but also had low torque . he then played with load setting on the RR and torque readings were nearer what you would expect.

My car had been experiencing some intermitant starting/missing issues, Iain traced after the RR day to a badly corroded Earth lead and bad spark plugs Car was running at 326g/s at peak power on the RR Day but now fixed 334g/s at peak power.

Tony, I have not read the full thread so forgive me if I am wrong but > not too sure who mapped your car but the torque appears a little low? I also have an "LM" turbo and when it was orihinally set up it gave 348 ft lbs, since Richard Bulmer at Tractive has mapped it the torque is MILES stronger. I would have thought the LM400 should be good for 385+ ft lbs?

 

Iain mapped mine Yes Torque is "Showing" low maybe due to these issuesThe car had problems and were fixed after this Graph

very nice

My mates EVO was 423bhp/396lbs he never left me and on a wider road i would have been by RR's fiqures aren't as good as Bum dyno's IMHO

 

Yeah I totally agree, the reason for my post was I always thought my torque was low but was assured by the original mapper that it was good/right for reasons X Y & Z, after a few months I thought I would get it mapped again by someone I had heard a lot of good things about. Once Richard mapped it, it felt twice as strong and was miles better to drive.

If your cars feels great on the road well that's all that matters pesky Evo's, move over

 

I made extensive use of ceramic coating several years ago, particularly on stainless, tubular headers as they are a pain in the butt to wrap properly. It was an expensive process and added a fair bit to the cost of the tubular headers, far more expensive than wrapping. We also did downpipes, uppipes and even had a try on OE cast headers. Using an infrared heat gun we did some tests and the ceramic coating did not appear to be any better than our DEI heat wrapping and after 18 months I knocked ceramic coating on the head because it was invariably flaking off anything that had been exposed to high EGTs ie. 930C or thereabouts in the uppipe.
I think you have to accept the flaking as a limitation to ceramic coating after numerous heat cycles. It is OK on Formula 1 cars, they only run for 2 hours in an event so even on a well used system the ceramic may only be exposed to heat cycling over 100 hours in a whole season if the original exhaust is retained throughout testing practice and races.

 

So its not just mine then

 

I will know better once I can get 410bhp to the road as I have the R2 LOL.

I will also post up my old graph to compare with it.

Tony

 

Tony,
All this is never straight forward mate, and what you acheive on the road (regards g/s) for a certain atmospheric condition, does not mean it will replicate to the same on the dyno.

Example in question......

1) On the road I managed over 330g/s with circa 13-16degs intake temps (higher intake temps would result in the g/s being reduced - as you would expect). This was back in September, so we know it will be much cooler now.
2) On the PS dyno I managed 324.84 g/s with 24degs intake temps.

All things being equal the g/s can give a good indication of WHP.

Did you log the run in DeltaDash when you were on the dyno?

If I went out and logged a run now, I would expect the g/s to be higher than 334g/s on mine.

I hope the spark plug changes have sorted your torque out mate.

 

Shaun LOL my iPhone reply And didn't know how to edit it

I am struggling to put 25bhp down as I still have the R2 I cannot get over to pick my car up

 

Has anyone carried out a comparison of the Litchfield LM and Scoobyclinic twin scroll turbos?

I planning on changing my VF36 in the late spring and I'm edging towards the Scoobyclinic SC42/46 based on the pricing.

 

This was discussed on 22B including the MD321 turbos, but getting people to agree on which Dyno and who was going to control the runs and n who's car was the stumbling point

 

I would think the Litchfield would make more top end - as the housing is custom made.

The p25 ihi housing scoobyclinic uses is abit small.

 

Shame that as I'd really like to see a comparison between the Litchfield and Scoobyclinic units, before I hand over my hard earned to either supplier.

I thought the Scoobyclinic unit was made for them by Blouch in the USA, but they (Blouch) use IHI VF series compressor housings?

 

what is the forecast on MKII variants?

 

... "Soon" .... ???

Just a personal 'In joke' .. just ignore me .....

 

I ask cause this baby can't wait to have MKII LM400 installed

 

VERY nice but your kitchen isn't very tidy LOL

Tony

 

The turbo's are blouch units afaik. 2.5xtr

Their twin scroll unit uses a ihi vf36/37 twin scroll exhaust housing. Presumably machined to fit the larger blouch turbo.

Whereas the Litchfield exhaust housing is custom cast - options for 2.0 or 2.5

Blouch compressor housings would be custom as they are way bigger than any ihi.

 

That looks stunning Ilya !!

 

The car is not finished yet, rear wheels need some spacers, even thought it sits on 9.5 +22 rims, I'm planning to swap AST rally line for AST circiut and obviously LM400 with 650cc PE injectors that I already have

 

pe650 with oem fuel rail??

 

most likely not

 

I just thought I'd update this thread to say that :

I've had the 420 on with the injector upgrade for about a year now on my MY05 JDM STi (without CAI or FMIC - approx 400hp) and I still LOVE IT.

I drove a JGM mapped MY06 JDM STi the other week (ie in a good state of tune) .. and whilst still a nice drive .. it just didn't have the grunt or top end that mine does.

So .. my conclusion ?? If you're not into chasing numbers and want a bloody good drive without the severity of some of the more powerful cars, I'd say 400 is about the place to aim for.

Gotta go ... off to get some more smiles ........
