i tot my engine blowed but i didnt hear any noise or anything ...... so i let go the accelerator for like 2 seconds ... then i resume on the gas .... the car was ok and still could accelerate....

petrol little less than 1 bar at that time....

can anybody tell me wat went wrong ??

i drove my car last nite and today to work and its behaving normal ...

 

Man are you lucky to run on that F1 track, LAH?

Anyway, when I'd track my 07 6spd auto with only 10k miles on it, it would lose power coming out of every corner unless it was full of gas when run started.

I put on the new BHR fuel pump assembly with stronger Walbro pump, and ran with 1/2 tank, and no power loss.

I think you aren't getting enough fuel since you're running over 100mph, and the stock pump just can't flow enough for the track.

So, tell us more about what it costs to run that track; I go to Indonesia a lot, and need to find a place to run, and rent the car, too!

 

Eh? How did find out that I was running on F1 track? Hahaha well i understand if u lose power when coming out of the corner with less fuel. Probably due to fuel surge. But mine happened when I was on the straight.

It has never happened b4 during my previous track days.

N I gave it a try today n went over 180km/hr and it was ok. But this time wit full tank.

So what happened in track? Fuel pump wearing out?

Sorry m still a noob. Haha n I need advice.
I rebuilt my engine once already. N I really dun want to go there again

 

Wah, still sounds like fuel pump since it's only for a few seconds, and when less than full after running for awhile.

The pumps and coils on the 8 are just good enough to get off the sales lot. Everyone should put on the BHR ign coil upgrade to keep the excess carbon off the apex seals, and save the cat, thereby getting a long life out of the engine.

The fuel pump thing can be remedied by running full; it's just annoying.

I've seen the Sepang F1 curcuit on TV, and when I went to Kuala Lumpar leaving the airport.

Also, some one here posted pics from there.
