Hybrid Turbos by Dan Jones. Article No 5 in a Series by Experts in the Industry

[adieu]

OK maybe I can get down to Power Engineering at sometime when Marco is around and just for a short while have the boost increased and map changed (Don maybe you can speak to Marco for me and see if he is willing?) and see what the car can do, just a test and not for long term running. Maybe then you will see further how a Hybrid from TT is better than a 19T.

All will be welcome to attend and if anyone wishes to test drive my car at the next C/B meet you are more than welcome.

But please remember you bash it you fix it....lol

well , my turbo choice is the RS500 spec turbo , with 360 degree thrust bearing etc , will be able to run 2 bar , and has a years warranty , just waiting for a space on the engine dyno .

ive spoke to dan at TT a few times when hunting for a decent turbo - incidentally the same spec turbo i use on my 740 turbo .

i agree the TT 'hybrid' is good value - but if you do enough searches the correct sized turbo is already available !!!

unfortunately , it probably wont fit in the correct space - so at a guess the hybrid is probably the best option compared to a 19T - if it has 2 years warranty .

Can I also point out (while I think of it) with regard to Dan from TTs view that a 19T is a standard turbo..... and that is that the 19T is only standard on one model of Volvo, and that is the V70R AWD AUTO MY2000.

On any other Volvo it is an upgrade.

You hear of plenty of T4s, for example, having 19Ts as upgrades. Are they still standard in that setup? Er, no.

Later,
Dan.

No but they are using a standard VOLVO turbo.

Volvo, as with pretty much any other manufacturer will source parts which they think is suitable for the application (for cost-effectiveness) and to guarantee longevity. That is probably why there is a different turbo type across the engine variants. So the 19T is suitable for Classic 2.4R AWD at standard boost, which is not 1.2 to 1.3 bar. You can take the turbo and make it produce 1.3bar, but that's not really what it was intended to do. I take it that's what Dan Jones means by taking a standard turbo (e.g. 19T) and fitting it in place of another standard turbo (e.g. 16T) to get a substantial power increase. You may be able to rev the pants out off a 19T to make it flow more air it was never designed to do that. On the other hand, Garrett turbos like the TT hybrid and GT series are designed to be able to run safely up a range of boost pressures up to a point, in the case of the TT hybrid 1.6bar and the GT series, 2 bar. You can run anything up to those without worrying about putting the turbo under a demand that it will have to work hard to cope with. Whether the engine will cope is another matter.

also - if you speak to most turbo reconditioners , the mitsu turbos are built a liitle bit more fragile than the garrett ie like a smaller diameter shaft .

getting to those higher boost levels requires , a built turbo .

unless you can find a mitsu turbo that is built to take those high levels of boost as std , like a 20g or something , then again , that will be a hybrid - in most peoples eyes .

Soon to be two. And anyone who wishes to pit their RICA-mapped 19T against me will be more than welcome.

Now that would be good to see... on an airstrip obviously! ;)

I would like to point out i had a hybrid fitted to my Mitsubishi Starion in 1994 the reason i was told to do this, Is that the Mitsubishi units you couldn't get rebuild kits for them at the time, and the Garretts you can get all the parts and spares on the shelf in this country. as they are fully rebuildable,
The firm that supplied me with my Garrett were Turbo Dynamics in Bournemouth.
Also with the 19t it isn't just a case of having the turbo put on the car, you need to get another Downpipe and cat for your car to run this plus a new cat back, as the exhausts and DP's are different diametre also with the 19t it requires another map to stop the rods bending. as we have seen in many cases in the States.
