Russia's finest Vodka in the tank? Should give the turbo some pep!

why not get a dual map done and add 20% methanol for one of the maps?

Ilya

first the LM goes back in and than we see

Shaun

Ilya,
Who is telling you 2ron will make 1000-1500rpm spool difference? I think they need to stop drinking it and start putting it in their tanks!

With regards to fuels, I'm not sure you can come up with general conclusions that the better the fuel the quicker the spool. You may actually find the opposite!

Ilya

i absolutely see what you are saying, but the thing is that in RUS petrol station do not sell real 98 ron, it is 95 with some additives, and the result is ****ty petrol. so guys are not saying 2 ron will make such difference in principle I think, but that 98 ron that is sold in Moscow is of poor quality. for u guys it is simple, u go to shell and buy 98 and u get 98, here it is a different story. i remember i re-fuelled on the very first petrol station of the ferry in Germany, and it felt that my car was re-mapped or something, real difference. so guys are saying in order to be able to compare results u have on shell 98 and i here on our 98, i need to get some decent petrol to start with

As of April this year the fuel sold by Gazprom Neft from it's Moscow refinery meets all Euro 4 standards, so it cant be that crap.

johnfelstead

and even if you only had 95RON fuel, spool wont be that affected, certainly not the amount you are claiming.

Maybe you could sumerise your full engine spec, because something doesnt add up.

The difference from 95 to V-Power might credibly be 100 to 150 RPM in spool to 1 bar.
Are you sure someone does not have the shakes on the keyboard accounting for an extra 0? Sounds like too much Vodka.

Ilya

because I am no expert I take part in this forum 4 advice, so I hear what u are saying I just had my hopes up

my engine is stock 2.0 JDM 06 spec C Ra
fujitsubo exh man + decat Milltek
air filter

and my billet LM400 spools to 1 bar at 4000rpm in fourth
the strange thing is that my original vf36 spoools as it is supposed to
so atm I am open to any suggestions, even the ones I shared few posts back

johnfelstead

Put the stock headeers back on the car!

Will second that - I used lateral/tomei/kakomoto type headers on my 2.5 twinscroll build at first, thinking they would be better. Bad move as they completely killed spool. Refitted OEM twinscroll headers and all was good again.

Ilya

i thought of that, but why do these headers support decent spool on vf36?

johnfelstead

Vf36 spools quite a bit faster than the lm400, so the effect of slow gas speed won't be as noticable.

Best twin scroll headers by far are the stock items, you always see worse spool using aftermarket.

Shaun

Time for another update and time for more LM power related goodness please.

Bit of a revisit to this thread but has anyone had their LM turbo sent back for upgrading say from a LM400 billet to a LM450 billet?

I have fired off various emails to Litchfield Imports and never got an answer, called them and no return calls.

I'd really like to get a costing on this as my car is off the road for a while and will be having the Simtek/Alcatek upgrade plus a Toucan and sensors fitted, so now would be the ideal time for get it all done together.

£195 + delivery + vat.

Just had an LM450 upgraded, it cost £316 Including vat, delivery and a repair to the actuator.

You're also better of dealing with Turbo Dynamics directly. I did and they were very helpful.

Thanks, I have just called them and they were very helpful indeed.

They are going to ring me back with a price.

This is the sounds of my SPEC C RA with LM450 turbo (stock ECU and with MAF removed) in 2nd, 3rd and a part of 4th with the Tomei TI exhaust (only 5.6 kg).

Shaun

That's way too loud for my old ears!

For completeness in providing information for this thread, here is my latest dyno graph for the LM450 Billet on 20% Methanol:

Come on Shaun with this system some ps more on your car and your ears will be improved .

Hey everyone,

I am an avid Twin Scroll Fan and had the chance to own several Twin Scroll Turbos.

I read the first couple of pages and saw that there was a discussion about:

Twin SCROLL vs Twin ENTRY

Kindly allow me to clear everything up.

Based on my findings, the HKS 2835 Twin "Scroll" Turbo is actually Twin ENTRY.

The HKS Exhaust housing does not have the same dividing scrolls from your VF Twin Scroll Turbos.

Pics below will explain everything.

Comparison is between HKS 2835 Twin "Scroll" and VF53 Twin Scroll Turbo.

Notice in the last pic, where my finger is able to go through the 2 ports of the HKS Twin "Scroll" Turbo.

Hence, it is evident that the HKS turbo is Twin ENTRY.

That being said, I have not seen any conclusive evidence of the Litchfield LM400/420/450 Twin "Scroll" Unit.

Would anyone like to share if the Litchfield Unit is a True Twin Scroll or Twin ENTRY?

Cliff notes: HKS Twin "Scroll" Turbo is actually Twin ENTRY as it does not have the dividing scrolls like the VF36/37/49/53 Twin Scroll Turbo.
