few questions about hybrid

[keirz]

is it possible to run a hybrid ct9 at 0.8 bar on a glanza and not have to change the fueling?

when running a hybrid ct9 are the oil feed and drain lines in the same position?

is the intercooler outlet in the same position as the standard ct9?

if you run a hybrid ct9 with the filter re located to the front bumper will it have the same creep issues as a ct9 or will it be fully eliminated by the ported wastegate?

and finally.........

how much would a fully reconditioned, balanced and surface treated unused ct9b fetch if up for sale? i have a plan.

any help good thanks.

yes it is, it would be wise though to invest in a wideband af gauge to check the state of tune if you go over point 8.

yes

yes

porting the waistgate will eliminate the creap for sure bud

if you are not running higher than stock boost. there is no point wasting money on a hybrid mate.

the ct9 is fine for a stock boost. hence why toyota chose it on the first place.

hybrids are only really worth hitting up if you plan on running higher than stock pressures (ie, 13+ psi), usual range for a hybrid is 1-1.2 bar.

[Guest Enzo]

the difference in power delivery between the hybrid im running and the standard ct9 is night and day, a worthy mod by itself.

[StarletRick]

how much boost you running.

because 10ish psi isnt gunna be burning the road up on any turbo if its put on a stock starlet.

hybrids are made for top end flow when compared to the ct9. thats the only thing the ct9 struggles with. its pretty good for low boost/response as stock.

[ecksjay]

ct9 is a response turbo, hence why it does at anything above about 80-100mph, hybrids are designed with larger compressor blades to eliminate this tail-off, hence why they're intended use 'should' be for higher boost applications. if you're not planning on upping the boost, even if the hybrid will make a difference, for the money, you could spend it better elsewhere. if you're going to up the boost, then yes, go for it, as it'll be worth the money with the additional performance all across the rev range that it will provide.

also geo, its been proven that porting the wastegate doesn't ALWAYS eliminate boost creep, especially if its cracked, it can help greatly, yes, but not 100% of the time, you seemed to suggest that it will (i.e 'for sure'), which could be a little misleading. Just a suggestion for future reference

[keirz]

the plan is to run the hydrid for now at 0.8-0.9 bar this is the boost im currently running, and then when i feel the need get a standalone ecu and up the boost and get a proper tune.

im not too sure about going the fcd and fpr route.

[StarletRick]

oh, in that case, yeah, hybrid it up.

make sure whoever you get one from offers a good warranty.

because ct9s are shit, and when hybridised they tent to die if not setup absolutely perfectly.

[keirz]

yeah that not be much of a problem rick as i re-condition turbos for a living.

not sure if im gonna build my own hybrid yet though.

[Guest Enzo]

@ Rick im running 12psi in the red v with a front mounted filter, gives me a nice shove into the seat the now.

@ ecksjay

a proper hybrid will have its waistgate ported already ecksjay.

could you tell me who still suffered creep on a hybrid ct9 with the waistgate ported?

and on buying one again they are your views,at 10psi the way in which the power gets delivered compared to standard would be enough to warrent buying the turbo alone to some people, me for one.

[StarletRick]

geo, i was talking in comparison from a small turbo to a large turbo.

any small oem turbo regardless of if its hybridised wont rip your face off. i was really getting at the fact that although itll give you a little push in the back, its never going to be as good as a turbo designed for higher end performance. like a td05 or something.

i also said a stock situation. you use a fmic, which plays alot to the power delivery. CT9s are way out of their efficiency band at anything over about 10 psi. they were originally designed for diesel motors that run only a few psi of boost.

thats why a fmic gives such a dramatic change to the 4e. because you are remedying one of the big flaws in the stock setup, the shit charge cooling.

at the end of the day, pressure plays its part, but its all about flow rates. for example my td06 flows more air at 6 psi than a ct9 does at 15 psi. you can only fit so big a compressor wheel into the tiny ct9 housing. so its never going to be a neck breaker. saying that, its not going to be a slow poke either. but the delivery wont differ that much from a ct9.

[Guest Enzo]

but the delivery wont differ that much from a ct9.

il give you a shot of mine at jae for you to compare, dont be a snob about it though just cause your turbos bigger than mine lol

[StarletRick]

lol, i wasnt being a snob mate was just an example

i think were mixing up our meanings i think youre thinking more power. which i agree, it will be much more powerful. but i mean delivery. a hybrid ct9 will still spool up low down and deliver moderate power across the revs. much like a ct9 but with more power. a larger turbo on the other hand will forfeit low down power, and be very unresponsive, but once you get it spinning it pulls your heart out and give you alot more power than any ct9 could.

ill take you out in mine, youll understand what lag is all about then mate, lol.

[Glanza_Ragger]

Turbo Dynamics built ct9 hybrid. good for 1.2bar and over 200hp easy.

Mine comes on full boost by 2500 which is what i prefer over a laggy larger turbo.

If i was doing lots of drag runs, id opt for either a td04/5 or gt turbo.

But i prefer trackdays so my hybrid is spot on for that.

If you want a responsive starlet, then a hybrid is the way forward.It wont push youre head back in the seat obviously but it'll deliver all the goods in little time

It all depends on what you want the car for at the end of the day.Theres no point chasing for big power in a starlet if youre not going to be turning it into a drag monster.

At the same time, you dont want or need huge power for track use.

They would be two totally different setups.When people brag about the power theres are putting out, i usually switch off.Alright its impressive saying oh yeah, 250hp, 300hp etc..But is it drivable..It it enjoyable to drive..

At this moment in time, my setup is good enough for the occasional drag run, and more than good enough for an immensely fun track attack.

So figure out what you want the starbo for, then build youre setup around that idea.Simple as.

Seeing as ive forged mine, i might just see how much boost i can get out of the hybrid, before it shits itself..Then ill look into different turbo setups.

Strange, i was only talkin to Dave Burwash today about different setups when i picked my thermostat up.

Rick, youve got to give me a rip in youre beast to see if you can persuade me to get rid of the hybrid mate
