max bhp with ct9 (not hybrid)
- Thread starter reyft
- Start date
180ish with the rite supporting mods
Actually one guy went over 200 with dyno graph, god knows how his tuner did it, but the graph was there... Do a search on the forum if you want.
Most likely around 170-190 mark depending on other mods.

Mine made 190 Bhp but there has been some make 200bhp with supporting mods

I think 207 is the record if you search on google for fc tuning and find the white Glanza on there it made 207

Little Ct9 boostin 200 will be puffed out an wont last long,ad recomend goin hybrid for similar set up 200+ an will pull like a train
I've been running 190bhp for about 4 years without a problem.

Nice buddy! @ 15psi
Standard management? Standard engine/head?

Think it actually made the peak power at 13psi, emanage blue and completely standard head - engine hasn't been opened.

My stock turbo made 200.1 with hdi fmIc at 0.9 bar with jam ecu and 190.6 on a arc tmic

torque is where the party's at

Not really, top end power gives a much better feel than a big slug of torque.
Also I lied - there is no way my car is running 190bhp at the moment, it sucks.

Take dyno numbers with a pinch of salt....
I do.... times from crail show that it's not anywhere near what it pulled on the dyno or how it used to be!
My comment wasnt just aimed at you Dave, when i see silly high numbers from a stock CT9 i just sit back and laugh.
x2 the tuner is probably just telling you what ya want to hear by entering different parameters it can show "better" results

The limitation of a stock CT9 is the exhaust housing, this becomes clearly apparent when the intake and exhaust restrictions of the stock setup are removed and the turbo suffers silly amounts of boost creep. I found the stock CT9a to creep to around 0.97BAR in 4th gear before manifold pressure would level out. Boost creep is a result of a restriction in exhaust flow, with a restriction to flow comes an increase in exhaust gas pressure in the exhaust manifold, this all has an impact on the VE of the engine and as such a limitation on the peak power the engine can produce with a stock CT9 bolted to it.
However, with an external wastegate it's a completely different story. I swapped out the large yellow TiAL spring (rated @ 0.7BAR) for a small yellow spring (rated at 0.25BAR) to test this theory. With the large spring the Blitz SBC-iD recorded an average peak inlet manifold pressure of 0.61BAR in 4th gear, after installing the small yellow spring the Blitz recorded an average peak inlet manifold pressure of 0.23BAR and held it to the red line in 4th gear. This confirms that a 38mm wastegate can flow enough to alleviate some of the restriction to exhaust gas flow created by the CT9 exhaust housing, which in turn should allow the engine to flow more air than what it could with a CT9 using an internal wastegate. With the engine able to flow more air it should as a result, produce more power.
Having said that, I have no idea whether the 38mm wastegate will provide much benefit to exhaust gas flow at a higher boost pressure in say 4th gear at 6000rpm. Once I've got the brakes sorted out I'll try and get the car to a dyno to get some graphs for the stock CT9a pushing 0.85BAR on the stock ECU. If it interests me enough, I may try the Haltech PS500 on the 4E and see what the CT9a can produce at 0.9-1.1BAR before dropping in the 4A (although that's probably some time away yet).
