[Mk2] [Turbo] Hybrid Turbos

[Adam86]

Whats different between the standard ct20b and a hybrid ct20b? In what way is a hybrid turbo better for performance?

[Marf]

Generally a hybrid will have a larger compressor wheel than the original turbo.

This usually means that the hybrid will make more power, at the expense of spool.

[Adam86]

I know every engine is different but what sort of extra bhp power would you hope for at 1.2 bar? 10bhp?

How much longer of a spool are we talking? A second or so?

Thanks for the advice

[Marf]

Hard to say, there are so many variables. Your best bet is to wait for someone who has fitted one to give you an idea of the differences.

Regarding spool, its not a matter of seconds but a matter of RPM before the turbo starts spooling up.

Ok bud thanks for the help

You make a valid point, but I would ahve said the biggest variable with a hybrid is going to be, who's hybrid it is.. TT will be slightly different to Fensports, Universal Turbos etc

They tend to have a steel shaft so they are a bit stronger

my tubbys ct26 gave up the ghost so decided to go for the turbotechnics hybrid rated to 380hp and 1.7bar (supposedly) imho i rearly didnt notice that much diffrence from the old turboto the hybrid apart from boost seamed to come as more of a surge of power rather than lag then a hit up the back side but when i say dont buy a TT hybrid please take my word for it, i bought mine brand new from them with 2year warrenty, after about 8months worth of use (on standard boost!) it decided to crap it self in a big big way intern destroying my engine so seriously there was nothing that could be slavaged, we sent the turbo to TT a week later got a call saying the turbo oil supply had become contaminated wich was utter crap as i had a garret inline oil filter and filters were regularly changed, they said id couldnt be fixed when i kicked up a major ordeal they then said it could for just over 600, i told them were to go, a few weeks later i spoke to T b T i M, and exsplained what had happend shockingly he had near on the same rpoblem on more than 3 of the cars who had come in with engine failure the fourth time he stripped the turbo down him self, there was NO contamination atall, he put it back together again and sent it away to them, once again there answer was contamination he responded that he had already inspected it, the denied they had made the wrong diagnosis and then said they wouldnt fix it as he had voided the warrenty, he never hurd from them again and will never deal with then again a lesson to all stay away from turbotechnics , i have hurd brilliant reveiws on the fensport hybrids i rearly wish i had fitted one of them you live and learn i guess

Never used TT, mainly because they were so damned expensive!

When I had my charade turbo I made a hybrid myself using the hotside from an old maserati turbo and the cold side from a 1600 Mazda 323 GTX.

Put it all together with the help of a mate then sent it to AET to be rebuilt and balanced.

The CT26 is the turbo to build a hybrid from not a CT20B. It has a larger turbine wheel and the shaft is bigger, the CT20b shafts snap.

I fitted a Fensport Stage 2 CT26 hybrid about 2/3 years ago now. Not wanting to tempt fate but so far so good. The main benefit for me is that the standard CT26 runs out of puff higher up the rev range whereas the hybrid holds boost up to the red line. (this was confirmed at a dyno day I went to a while back)

As has already been mentioned the steel shaft is also a bonus being more sturdy than the standard ceramic shaft. Mine is optimised to run at 1.2bar but I've never had it above 0.9bar. Now I've got my IC fitted I'm gonna raise the boost up to 1.2 and see how she feels

You probably wont notice much if any difference simply fitting a hybrid, but its the hybrids' ability to run at higher boost levels that makes the difference.

LOL @ the TT excuse. I wish I had a pound for every time they said that to a customer.

Perfect get out jail free card for there shockingly bad turbos.
