How does the clutch feel ? Working well ?
Thanks guys!
The boost on the dyno graph shows 1.07 bar, but we are not done with the adjusting on the higher rev range. If i have my wastegate fixed we will continue tomorrow.
The clutch is great! Not too heavy on the foot, You just need to get used it it but id say its friendly enought for road use yet still holding on nicely...will see what it does once we reach 400whp and 450nm torque on the wheels. But im expecting it to hold on.
Welk done.!!! Nice power out of the CA!:shock: Impressed!
Thanks Drillergy
When we continue i hope we rev past 7500rpms atleast (want to set the limiter at 8200rpm's as the car peaks at +-7500rpm.
I see the guys put my cab on their site 🙂
Hi Guys
Still busy with the tuning but here us up to the current progress.... (I must admit i feel sorry for all the guys who changed the ca out for a sr hehehe)
Dyno @ 1 bar 
Dyno @ 1.2 bar Dyno shows 1.3 but Johan says the dyno shows 0.1 over)...but we had a little issue so we stopped for now, some more hp to gain here. But i can see where my turbo's efficiency range is truly coming through. 
very nice figures!
Lovely stuff there man. Very nice build!
So is the Dyno figures on the wheels or the fly?
Hi Charl...Thats wheel Hp. (No correction factors etc)
Very funny to see how the figures compare, my friends V6 twin turbo made 390whp on 0.7 boost on the same dyno.
I would ques his graph look completely deferent tho. What torque did he make at .7?
Hi Charl,
Here is a copy of his dyno run posted on their web site.
His run was pump gas only.
He has loads more Torque and hp available at low refs, but my car is fine. It idles and drives like stock on the lower rpms....
Here is run of a rb25det (308whp @ 0.7 bar)

And here is a run of another Ca18det monster... (592 hp and 666 torque)

Nice Eugene, looking good, after the tuning you gotta start taking the tracks.
What's the lag like on your car Eugene?
Most people will rate the turbo as "laggy". But my built i purposely built for high rpm, because it is also a street-able car. The car drives and sounds perfectly stock under 3000rpms. It actually has more power than a stock ca18det on low revs and it’s much more of a pleasure to drive as it doesn’t feel so lazy. Its just the clutches you need to get used to but due to my mod, it has all the bite but im able to slip it a bit which is also very pleasant compared to the crude options otherwise available.
You can hear the turbo build up pressure by 2500, @3000rpms the boost picks up as it goes into positive boost, @ 4000-4500rpms the turbo kicks in and at 5500 rpms I have full boost, my rev limiter is set at 7900-8200rpms. Ideally it should be revved to 8500rpms, but that will happen once i replace the valve springs and solid lifters for extra security. Allot of people i know including others on the net claims the ca18det to be 8500rpm save. Apperently the stock springs has the same capability as the aftermarket Sr20det BC springs.
If I may give some advice, this is my theory derived from my experience, on boost at around 1 bar or so going to higher revs should be ok, but as soon as you going to start boosting more the boost pressure plus the revs will increase possibility for valve bouncing, in 1st to 3rd it might hold but on the longer gears it will not hold to 8000rpm on high boost, my advice is to do at least the valve springs now.
no new updates?
Hey guys,
So i pulled the motor to see what exactly is the fault, and i found the following on piston 1 and 3....Whats your ideas?
The motor had a slight smoke to it and breathed after it came back from the dyno at a famous jhb guy...so im wondering....if its fixed up i am sure it will make more Hp than it currently made with this slight smoking problem it picked up in jhb (386whp)
Who has a block they would like to sell?.....i will measure but i think the sleeves will need a re-bore and i am already at 83.5 so fitting 84mm is not a option because that would mean that i need to get a new cometic head gasket and import pistons which would be costly as well....i guess if i cant get a block then i wont have another option but to import 84mm pistons and head gasket.
Which tuner? Name and shame
