207bhp on stock turbo

Fresh Recruit
I have been thinking about this and please forgive me if I sound silly, but by using a higher octane fuel, will this not figure be achievable with a stock ct9?
I.e by increasing boost as well as the ignition advance without detonation.

Or maybe he is using water injection...

i have graphs for afr , torque , tractive effort , boost and graphs for before and after also on the hp and torque graph they cross at 5200 rpm and 200hp and 200lbft. Mike will take you up on that offer matey! I am not fussed if people believe me or not to be honist ,if you dont believe the rr results then ok thats fine....end of

No worries mate and dont think by suggesting that I doubt the figure I just thought it would be a good way of vefiying the figures for you. At the end of the day you already have the proof!

Why are you so defensive?

Just for your information, it was a Subaru forum I was looking at, nothing to do with Starlets.

I am sincerely interested in how he managed to get that figure if it is indeed accurate assuming the engine is internally and cam stock.

I would want to know the same if it was a TD04L on a stock 4EFTE that produced 307hp on the rollers.

Why blindly take everything as gospol? Why not ask questions and educate yourself?

Thats what I am trying to do.

I don't know shit about CFM etc, but thats why I'd like someone to come a long and explain this and how the CT9 can theoretically produce this figure if so.

I'm only going by empirical evidance.

Anyone like to mess with numbers?

1 HP approx equals 1.45 CFM
1 CFM approx equals 0.0745 lb of air/min
0.108 Lb/min approx equals 1 hp
1 Meter cubed/sec = 35.314 CFS = 2118.867 CFM
1 KG/sec = 132 lbs/min approx equals 1771.812 CFM



power coversions:
1 PS = 0.9859 HP = 75 Kgf m/sec
1.3405 HP = 1 KW
1 HP = 746 watts

You have a lot of numbers there and still you have no answer ! when tuning you could make 2 engines identical in everything and still you will get different bhp from both engines! So I am running a Mr Turbo efi ecu and zisco mani which both are probably contributing to the high bhp i got . If you see the spec of that glanza you will notice it has a zisco mani too so that must be one thing in the equation from where the power is coming plus im running a ct9b which i see that its much better than the ct9a even tough its not rated much and people say it only just has an extra blade well that blade is there for something ! As to get the most power from your engine you must have a good map a thing most of you dont seem to have as most are mapped on the rich side oh i meant safe side so will never know what your engine is capable of .My car was mapped for 7psi with the tmic so it was a bit rich as it was running a bit hot then i fit the fmic and turned the boost up and the map was came spot on

gee - so you want to know how a good map can be done? im sure no one will give there own secrets on mapping engines.

good map is all you need. most of the tuners tend to map at the rich side.. to be safe and not much agrasive on the ignition side cos they are scared. so i guess there is a very good map with a very good ecu in that starlet. ;)

im sure you all agree that the ecu plays a very big part for power output!

guess its not only in malta anymore? :)

That extra blade is on the exhaust turbine. It will have no effect on the peak volume of air the turbo can shift, thus absolutely no relation to peak engine power.

This is decided by small changes in the compressor, inducer, exducer and tip measurements - and obviously compressor design if a different model or make.
These all have an effect on its ability to shift air mass, at what rate, and ultimately how efficiently.

Personally I have never listened to anyones power figures and claims on this board, although I think it's a good thing that those who were previously all about 'figures' are trying to understand how they are acheived.

But the most important factor to me is the area UNDERNEATH the complete power and torque curve from a dyno print out.

That makes for a fast and enjoyable car.

I'm not sure how boasting about obtaining 1337bhp 'atw' with 7psi is doing any favours in this thread, other than feeding a fire that is.

you should look properly before you write its 135bhp not 1337 :homer: and you would doubt even a rr chart cos you guys are like that and you cant teach an old dog new trick

but thats not possible at 10.9psi is it !

Cos maybe the guys posting this shit have tdo4 turbos on which are producing 210 -240bhp so they dont like that with the little ct9 it is close to their bigger turbo with all the money and hassle they had fitting it :drive:

that has so much to do with it you wouldnt beleave


and how do you know you had 275bhp??

well gee??? sorry but he has a good point how do u know u made 275 did u go to another rolling road??


has someone said above most ppl dont have Standalones on the lil CT9's they just run rfpr and fcd.
so they gonna get a great result has tuning is limited
and how many hear really push there engine's to the limit wen tuning who are closer to running lean then mega rich with very aggressive ignation timming??

end of the day it says he has 207bhp why should we doubt it?

this threads getting a little outta hand! guys i dont think anyone is doubting this guys mapping abilities,just think everyone is curious how a little ct9 can reach that power ie what supports it and if this guy can get that figure on the ct9 which peforms well on the track there is no doubt what so ever i personally will be paying him a visit for a tuning session.

Nexia -

Those numbers are to calculate the max theortical output the CT9 is able to produce. What has that got to do with Zisco manifolds?

Sheldon -

Not the secrets of mapping, but evidance that the CT9 theoretically able to produce that HP output by its compressor maps calculation from the details I posted.

Spoons -

Don't think you guys understand. Maybe my car was not 275hp, but atleast I know the TD04L is actually able to produce these figures. Thats the point I am getting at, is a stock CT9 actually able to produce those figures at 1bar on an internally standard 4EFTE?

No matter how super the tune, at turbo can only flow so much air and produce so much power!

Obviously there are ways of cheating...putting ice packs on intercoolers and running race fuel etc, but like I said stock 4EFTE (not I am not suggesting this was done for the before the idiots start).

Dude,

Seriously, I am not arguing. I'm not jealous. Makes no difference eitherway to me if it really is 207hp, I'm just interested to know the details!! Dam, I don't even own a Starlet anymore!

Anyway, catch ya laters guys.

I've bitten my lip and not got into any of the EK9 vs Starlets threads threads so don't know why I am been pulled into this thread!

oh yeah there are people that dont think the rr figures are correct. so doubting this guy. read the thread again lol.

Just trying to bring a little love in this thread lol :kiss:

What it is mate i think people are generally shocked that it actually made that figure (too good to be true) hence they dont believe the RR figure.

But im pretty sure it did make that figure, & pleased to see yet another ep enthuiast do something that makes me love my starlet more lol

If stock ct9's can produce that power, imagine how it would be on the track! :drive: uber fast spool up.

Of course once he goes on mikes Rollers & produces same figures it would prove to everyone just how powerful the stock CT9 is.

the thing is that not much people got that figures so its fair enough to doubt him but most of the people think its not possible just cos they didnt get that power!

i Understand what you mean, but reading through the thread there are a good few debatable points, how many poeple actually used stock turbo on a stand alone ecu? not may. how much can the stock ct9 actually push out?

As i said i do believe the figure he got BUT there must be something else to it then just a map with the ECU!

There must be something else supporting the little CT9 to achieve that power!

Im curious to know what it is ;)
