Turbo MHI TD05H?

[75ts]

Jel ima neko mozda specifikaceje, ili neke informacije o ovoj turbini, forum sam razgledao ali nista nisam mogao da nadjem o ovom tipu turbine.

[Nenad]

To je starija Mitsubishi (Mitsubishi Heavy Industries=MHI) turbina koja se ugradjivala na Galanta,Eclipse krajem 80ih i pocetkom 90ih,Chrysler Laser.
Isla je i na Evo III za japansko trziste.
Kao i uvek ima je u nekoliko velcicina

MHI Turbo Nomenclature

Mitsubishi Heavy Industries' (MHI) turbocharger nomenclature, such as TD04-13G-6cm2, requires some explanation. "TD04" and "TD05" refer to the turbocharger housing (either turbine housing or compressor housing or both), including the center housing (or CHRA or cartridge section). There are different styles of the basic housings and these have different suffixes appended to the basic designation, such as TD04L, TD04H, TD04HL, TD05, TD05H, and TD05HR.

TD04 housings have part numbers that start with 49177. TD04L housing part numbers start with 49377. Part numbers for TD04H and TD04HL housings start with 49189. The TD04HL compressor housing is easily distinguished from the others because of the integrated by-pass valve (see the pictures of the SL/MK TD04-18T hybrid below). The TD04LR-16Gk-6cm2 turbo (used on the turbocharged 2.4-L I-4 engine in the new PT Cruiser GT and SRT-4 Neon) is unique and not usable on our cars: the turbine housing is cast into the exhaust manifold, the impeller spins counter-clockwise, and the bypass valve is cast into the compressor housing.

All TD05, TD05H, and TD05HR housings start with 49178. The TD05HR turbine housing (found on the Mitsubishi Lancer Evolution IV through VIII) is a twin scroll design. All the other TD04 and TD05 turbine housings have a single volute in the turbine housing. Like the TD04LR, the "R" in the designation refers to the fact that the turbine wheel spins in the reverse direction (counter-clockwise) compared to the standard TD05H turbine.

The MHI part numbering system, and the possible combinations, can be somewhat overwhelming and confusing. For example, the MHI Sport Turbo Upgrade for our cars is usually referred to as the TD04L-13G-6cm2. This turbo clearly has the standard TD04 (49177) housings (at least by external appearances). However, both the stock TD04-09B-6 and the upgrade TD04L-13G-6 use the 49377 cartridge (but note the different complete part numbers) from the TD04L turbos. TD04 turbos used in other cars (even some other TD04-09B turbos) use the 49177 cartridge.

The "13G" in the model name refers to the compressor wheel. The "13" is the size and the "G" is the style. The 13G wheel has an exducer (or base) diameter or 2.000" and an inducer diameter (air intake opening) of 1.580". All MHI wheels I have seen have 12 blades. Blades are always evenly spaced, but the pitch and height of the blades can change between models. "B"- and "C"-style compressor wheels have all blade tips at the same height. "G"-, "Gk"-, and "T"-style wheels have blade tips at two heights, alternating high and low.

Mitsubishi does not seem to use seperate designations for different size turbine wheels, other than the TD04, TD04H, TE04, TD05H, etc., designation. The "6cm2" in the model name is similar to the A/R ratio used by other manufacturers. The "A" in an A/R ratio is the cross-sectional area of the smallest intake passage in the turbine housing before the passage spreads around the circumferential volute that leads to the turbine wheel. The "R" in the ratio is the distance from the center of the "A" to the center of the turbine wheel. The MHI "6cm2" designation is just the "A" in the A/R ratio, that is, it is just the cross-sectional area. Like A/R, the smaller the size of the "cm2" number, the faster the exhaust gases will discharge onto the turbine wheel, and so the faster the spool up will be (less "lag"). The size of the "cm2" number or the A/R ratio also determines the amount of exhaust gas backpressure and, thus, reversion into the combustion chamber. A larger "cm2" number (or larger A/R) means less backpressure at high exhaust flow. Extreme Turbo says that the TD05H-7cm2 housing is equivalent to a 0.50 A/R. The Rocky Mountain DSM turbo guide presents the following conversion between Mitsubishi's "cm2" number and the standard A/R.
6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R

A ja se ubi trzeci na ovoj mojoj A/R

Mada cela oznaka ove sto ja imam je Piaggio Mitshubishi TD 05H-ZB/6
PN 60513721

Pa sam predpostavio da je to ustvari MHI TD05H

E sad po pretpostavka da je ono 6 u stvari 6cm2

Inace skinuita je sa Alfe 164 V6 Turbo.

Ako je td05 sa 6cm2 kucistem turbine onda je ili td05-14b ili td05-14g....
