hybrid turbo Options

[pikey]

hi all just thought id let everyone know the results and differences in my hybrid turbo from the standard one after the old one broke. the unit is a stage 2 hybrid ct20b unit from turbo dynamics via fensport and rated up to 360bhp. it was mapped on thursday at fensport making 1.1bar bottom and high rev range with 1.2bar in the middle wich gives a nice little kick half way through.

noticable differences are reduced, harder (more aggressive) spool up time. also very very smooth all the way through and pulls very hard. 1 bar is available from around 3200rpm and 1.1 after 3400rpm wich holds all the way through.
my view is if your turbo for whatever reason becomes faulty, rather than buying the standard one, pay a little extra for this stronger uprated one.

as a bolt on mod its great value for money at around £800gbp rather than the standard at around £650, theres minor work to be done as the actuator is different and requires a small t-piece to link up the hoses but thats it. the car will need a remap aswell. all my details are on my profile if anyone is wondering what else im running and rough power figures.

details of the turbos can be found at fensport.co.uk thanks for looking

Nice info...think ill give this a try sometime soon myself...Also, _jim_, is running that high boost safe for your turbo and engine? Ive always read that 1.1ish-1.2 is pushing the limits of the stock turbo already..

Yes, I wouldn't recommend pushing the stock CERAMIC CT20B over 1.2 bar (18psi).....But I am running a WRC motor set, so I have the Steel wheel CT20B, which can withstand A LOT more abuse then the ceramic one.

As for the Engine, these boost pressures are fine. I daily drive my GEN3 at 21psi/1.4bar on 93 pump, and will continue to do so when I receive my new turbo. Basically, as long as you are not knocking.....the motor is perfectly happy at 21 psi. I turned the boost up on the dyno and listened for knock via Detonation cans. I didn't hear ANY knock at these boost levels, nor did I see any signs on knock on my pull. I even had an issue with the boost controller and made a 25psi pull, and still walked away without a scratch. If you plan on running above 15psi, I would HIGHLY recommend using Water Injection.
