Turbo Specifications.

[chrissyong]

Guys, I have a question for all the sifu. I know all of you very expert in petrol engine, then how about diesel engine like toyota 13B-T engine? What the different between diesel and petrol engine turbo?
Can diesel engine turbo install BOV??

PS: I'm just a newbie, want to ask and learn things from you all. Hope I can get the answer...

the diesel engine is got strong solid internal can boost 2bar anytime if got tuning, the 13b-t seem like is the rx7 engine bro?sure u can install bov to any turbocharger engine~

Ohh~~~ I think RX7 is 13B. This 1 is 13B-T(http://en.wikipedia.org/wiki/Toyota_B_engine <=13B-T engine info), if I not mistaken, I ever saw this kind of engine in a BJ40 during 4x4 competition.

One more question I want to ask is that I know that diesel engine run on low RPM, but I thought that we need to rev the engine until certain limit then the turbo kick-in? Then if want to make the turbo kick-in, then need to keep stepping the gas and keep revving?

not need wait too long,diesel engine all is short power band,at low rpm will turbo kick in already,like 5k rpm like that the power band drop very fast~

 

[Alexzai]

oh... like that 1...
Thx bro, I learn alot thanks to you.

BTW, what does short power band mean???

engine power out put map~can u see the power band?this car after 5800 rpm drop power band,good luck

 

[chrissyong]

oh... like that 1...
Thx bro, I learn alot thanks to you.

BTW, what does short power band mean???

short power band mean is the engine cant do hi rev or hard to keep the power to red line~

 

[lozo]

short power band is where the peaks happens only at a short range across the engine speed

[Alexzai]

So that what is mean by short power band. Thx man, it help alot..

you are welcome,but im still learning.....

guys anybody can enlighten me on garrett ar48?
coz i do not know much on this turbo.
what is the size like compare to like TD04 and TD05?

Garrett Turbos:

Garrett basically has two lines of turbos. The ancient, inefficient T series turbos and the new, modern, ball bearing GT series turbos.

*
T family has T22, T25, T3, T350, To4B, To4E, TS04, To4R ...These are 50 year old, WWII generation turbos.
*
The newer line of GT turbos are ball bearing on journal and thrust bearing. The turbine and compressor wheels are improvely aerodynamically to flow more air. GT20, GT22, GT25, GT30, GT35, GT40, GT45, GT50... GT turbos produce slightly more hp then older T series turbos with the same number designation. A GT Garrett turbine wheel wil flow more air than similar sized Greddy turbine wheel. Thus GT turbos are able to boost higher and flow more.

Turbonetics and many domestic makers turbos based on T series turbos. A T3/To4E 60 T .63A/R is a hybrid turbo with T3 turbine, To4E compressor, 60 Trim compressor wheel and .63 A/R turbine housing.

Wheel "trim" refers to the squared ratio of the smaller diameter divided by the larger diameter times 100. Generally, the larger the trim number the more flow the wheel has.

For compressor wheels , larger trim tends to mean slightly lower efficiency.

For "families" of turbine wheels (those with the same inducer diameter), larger trim usually means better flow with less backpressure but longer spool time.

A/R is a ratio of the exhaust discharge area vs the distance from the center of turbine wheel to the center of the cross sectional area. Smaller A/R housing has faster spool up. Bigger A/R housing has less back pressure, more flow for the top end.

The so called "T-series': T60, T61, T66, T70, T72, T76... are T4 turbos as well. The number means the compressor inducer size. ie: T76 means it has 76mm compressor inducer.

HKS uses Garrett turbos. HKS GT series turbos use Garrett GT's turbine with GT's compressor.

For example, HKS GT 2835 is GT28 turbine with GT35 52 trim compressor.

The newer line of Garrett GT-R turbos are hybrid turbos. For example, GT30R is a hybrid of GT30 turbine mated to 56 trim GT37 compressor.

The R behind the numbers means ball bearing basically...
GT4088 is a non ball bearing unit. But GT4088R is a ball bearing unit.
