Subaru wrx with vf30 turbo


Subaru wrx with vf30 turbo

Car comes with a vf-30 turbo, upgraded fuel reg, pumps and injectors and many many more. Boost at the max possible for his engine :). Tuning is via open source reflash.

Vf30 is a mid-range turbo, not too big and also not that small. It is a turbo that is good enough to pull a 220km/h without any hassle. Low end wise is still acceptable as you can still get a fair amount of boost even at lower gears. Sam in particular likes this turbo alot...kekeke... i personally prefer a bigger one since I have been using the VF-30 for a good 2~3 year liaoz...

What we did on this ride is solve the constant stalling and also prevent the car from jerking all the way during top speed runs. This ride has been previously tuned by an Australian tuner Henry followed by Garxxx R tuner Rhoxxxx. Owner approaches us because of various reasons and mainly because we were recommended to him by his kakis.

A vf-30 on a WRX will mean boost start building up at 2000 rpm and hitting max boost at 3800 rpm on gear 1! Torque wise, no doubt about it. A comparable turbo to the Vf-30 would be the Vf-28. If you have the budget, a VF-22 ball bearing turbo will give a pretty similar feeling and you can expect a much stronger high rpm power. Very much a give and take thingy.

Idling is 500~700rpm, no stalling, we also discussed this with the owner and asked if he preferred it to be at 1000 rpm. Well, car idles very quietly at low rpm and saves petrol. So, we decided to keep it 500 until maybe one day, he decides to put in a big bang kick ass muffler, we'll definately retune to idle at 1000 rpm for that kick ass boxer boom. My personal preference is low rpms and comfort kekeke...

Car now pulls hard at 3500 rpm ~4000 rpm and at 5500 rpm, the turbo starts to lose its efficiency and screams its way to 8000 rpm. Sam like it alot lor... kekeke... I keep reminding him my car also using this turbo and how come I dont feel the orgasm lor... If he likes the way the car is running, I bet the owner is also happy.

I have never met the owner before (as usual).... so, that evening, sam drove the car to the owner's house to pass him the car, and that was the first time we met. Owner is very friendly and easy going. We then demo the car to him and also show the fixes on the stalling part. He was very happy with the results. After a couple of pulls and demos, he starts to tell us how the car was like in the past.

Then after a while he sarted sharing with us an encounter with the 'unseen'. He said, not too long back, he and a couple of friends were driving up to malaysia. His ride was pulling around 180 km/h along a stretch of road where a week or 2 ago, the tour bus had a fatal accidient leaving numerous passengers dead and injured. 180 km/h in the wee hours of the night, all his passenger suddenly stopped their conversation, and braised themselves for a collision near the site of the fatal bus accident site. All except the driver who was puzzled at the sudden strange reaction of all his 3 passengers. He immediately shouted over to them and demanded and explanation for the strange sudden bazare reaction. His passengers were too shocked to say anything at that time, at that moment, he noticed a lady floating past him on his right and that caused his to swerve his vehicle to the left into a near accident. I couldnt recall if he did hit the rails during that maneuver, but it was good enough to note that after that incident, his car met 3 accidents within a month with cars hitting him from behind.

The passengers account was that they all saw the car hitting a lady. Which made all of them react in that bazare manner all except the driver. When there was no impact experienced, they continue to see the lady standing on the same position as-if the car had passed through it. The owner did notice from the rear mirror someone standing in the middle of the road and sensed something was strangely wrong.

Listening to his strange encounters send chills down my spine. Sam says if the owner told him earlier, we would have chickened out tuning his ride kekekeke.... Some would say that the owner's kind nature had prevented any mishap...

Ok, great ride, good turbo.

coming soon...
