Any other things we should consider?

Conrad

Price.
Longevity/reliability.

Price of the turbo, good point. Longevity of turbos is not really an issue these days with modern turbos (that I have across anyway )

Turbo shootout conditions.

Same car everytime,
Same fuel everytime (Optimax nothing added),
Same rolling road road everytime
Turbo supplier can have mapped tweaked or tweak it themselves in terms of fuel, ignition but boost level must be fixed @ say 1.5 bar for all turbos.

The winning turbo would be the best all round turbo, based on;
1. torque ( area under the curve D )
2. how early it spools and at what RPM full boost is achieved
3. peak horsepower within 5% of traget
4. price (Including VAT)
5. fitting ~ any hassle to fit, parts missing, new water pipes? Grinder needed?

Any more?

Looking good. What turbos and suppliers are in?

Bob

 

None by the looks of it !!

 

[QUOTE=Andy.F;4498754]Yes, sure would Although I think the "masses" you refer to already have a fair bit of info on these turbos
As long as your test is not just about peak figures but looks at the power available under the useable rpm range, after all this is what determines a fast from a not so fast car. The peak figure is really just 'pub talk'

I am currently undertaking a similar exercise, where I'm taking a 03WRX through a range of turbos, starting with the TD04 which with a slight mod is currently making 330 bhp with full boost from 2600rpm.... that makes it an uphill struggle for the TD05-16G which is next in line for testing, followed by the well proven 18g and 20g.

AN OLD THREAD I know but was this exercise ever performed and were the findings publicised?

 

Does anyone know if this test went ahead and if the results were publicised?

 

So, is the compressor swap up and running.? Or done just for test purposes? If available , how much?

 

Stay away from this turbo,its very laggy from what I've seen them on the few cars
