This is a very heavy car. With a 1.6L engine on 1.4 ton, it faces difficulty moving up steep slopes. Owner is a day-to-day sane driver, he is not a racer and has no interest in racing on public roads. I'm trying to paint a nice picture of a normal family man driving on the road la... so, get it right. We are building a turbo system to improve on daily driving. This is not a racing setup.
The turbo we used has resulted in a car that doesnt require dropping of gear to go up steep slopes or dragging that 2nd gear when you're ferrying your kids and groceries home from the supermart. The turbo will spool up to give that extra 40 bhp when you step the pedal more than usual at the 2000 ~3000 rpm region.
We used greddy emanage ultimate together with bigger injectors for this car. The turbo is well hidden from privy eyes and not visible when you open the bonnet. This is a very discrete setup and the only give away is when you're in the car and hearing the turbo spooling and stuff. Idling is smooth and since its automatic transmission, gearing is also smooth. Car drives and feels very stock during normal day-to-day drive except when you throttle a little more than usual, you can hear the turbo spool up.
Owner joins us for the tuning session and he told us he has never gun the car this hard and drove this fast before... hahaha... no choice la, have to pull all the horses during tuning. During hard driving, there is some torque steer induced from the turbo and a nice early g-force feeling at low rpms. At high speed, this kit starts to shows signs of breathlessness and lack of luster at high rpm as compared to the normal drag kit we normally do. The 2500~4000 rpm shows the most amount improvement.
Tuning this kit is more complex than usual since the control of the stock ecu becomes more difficult and requires more accuracy for it to work normally. Owner is happy with the results. For those like myself who prefer to win that drag race, I would go for a drag setup. For that reason, we boosted 0.7 bars on this ride which satisfy our own desire for bhp. Since most of useful boost is at the 2~3500 rpm region, this kit is really meant for quick overtaking and improving low end response.
When you read this article, try to understand that I'm more into a race setup. So, this article is written by a racing bias author hahaha... Like I said, owner is happy. No point giving him a drag kit that spools up at a rpm he almost never visits. We seem to be the first people that dragged his car to 6000 rpm. I'm serious. Anyway, owner is happy. Period.
verdict:
Feels very much like a supercharger kit.
Good for improving low end torque and horsepower
Very discrete.
On the flip side,
Not meant for street or drag racers. Whether this is flip side or not, as far as racing is concerned, this is a flip side. You decide.
