2.0 Liter Dyno Sheets

[rico]

Anyone know where I can find dyno sheets of 2.0 liter turbos - with specifications on there turbos.

Thanks

they have dyno and specs on their 2.0 DOHC 420a mitsu RS with complete info on their setups. if your wondering about an eclipse talon neon etc 2.0 they are the place to look.

Why don't you figure out the VE of the engine your using and add in the airflow calculations for the size of turbo you want.

I did it with my car out of bordem and was only 10hp off the real world figure.

2.0L B18C1. Going to be using a SC61 .68 T4 with a P trim wheel.

Not your grandmas turbo by any means.

I got a T3/T4 turbo on my car - not sure what the spec is. Turbos not giving what I want - I'm looking at the Garrett GT BB range.

I already did my calculations at a VE of about 85-90% (Standard, the car puts out 115Kw - non turbo). I don't wanna boost higher than 1.1bar. At 6000rpm, 1.1 bar boost, the car will be consuming about 32-36 lb/min. This gives me about 310hp (+-230Kw). This is what I'm hoping to get.

Thus I need to get a compressor with maximum efficiency at 1.1bar boost, that will flow about 34 lb/min. I'm still doing some research on what the best way is of plotting and useing a compressor map to make a good compressor choise. There's so many trims, AR ratios - can get confusing...

Theoretically, I think, it will be something like a 71mm, 56trim, 0.5/0.6 AR type of wheel.

The other thing is, I don't want the car to be dead in midrange - it is a daily driver. Garrett got a GT3071R turbo (http://www.atpturbo.com) - Ball bearing, Compressor: 71mm , 56 trim, 0.5 AR (T4). Turbine: 60mm, 84 trim with a 0.63, 0.82, 1.06 AR choice (which one should I pick??). The compressor on this turbo will be fine (I think), but I'm worried about the turbos respone? I see they use a T25 exhause housing on the GT25/40R), but I think this will be restrictive. The other problem is: I can't find a compressor map for this compressor.

The other thing is that garrett, for example, does not have a list of all available compressor wheels, giving a compressor map for each. They only have a few in there catalog (BB turbos).

What will the best compressor / turbine combination be??? Difficult question!

Why are you putting a limit on your boost? From the posts made by some of the other members it sounds like you should be able to boost more than that? Is that not true?

[rico]

My crank went (bearings could not take the punch) on 1.4 bar boost. Basically anything above 1.1 bar, I'll need to upgrade the engine. This is my second motor - done about 17000km with it. I don't wanna mess it up again.

GT32 =35lb/min (52trim, .78a/r or .69a/r turbine)
GT35 = 35lb/min (52trim, 1.18a/r turbine)
GT37 = 36lb/min (52trim, 1.12a/r turbine)

Those are off the new Garrett catalog.
