Loss Of Power After Spirited Driving

[R33Turbo]

Now what i mean by 'spirited driving' is not really from traffic light to traffic light. With a mate on a rolling start ive pushed it and braked to start on a roll, over and over again. Then there was a point where i realised that i was losing power, getting BOV Flutter as if i have no BOV, and NO pod filter intake sound at all! The weird thing is, i only get this issue for about a minute, then it goes back to normal where i gain the power back, hear the bov properly and also hear the intake sound. If this was the first time, i would of thought i heard wrong, but this is the 2nd time it happened. THe first time was after abit of spirited driving in the same style as well.

Ive got a HKS SSQV BOV, and im not sure if its real or fake cuz ive just bought it 2nd hand privately. Im thinking maybe it could be the BOV as i haven't had this issue before i put the HKS BOV on. But its been a long long while since ive put it on and i haven't noticed it so far till recently since i haven't really had much spirited driving or track since.

What are the possibilities for this happening?

- HKS SSQV BOV ( LEAK?)

- My Stock TURBO?

Need some help on this guys. Thanks alot for any input!

boost leak test is where I would start.

sounds like your BOV is getting stuck open...... take it off, give it a good clean , check its set correctly etc....

Block the bov off completely to determine if this is the issue.

thanks for the replies. If i block the BOV off completely, wouldn't i still need to give it a bit of pushing to wait for it to occur again? Cuz its very random.

Im going to try put the stock one back on to see if it solves the issue. So everyone is just agreeing that it may very well be the BOV and can be nothing else such as the turbo? Cuz the pipes are all fine and connected. Should be no leak but then again, its a random thing so... I don't get iT?

are you still running the standard rubber air intake to the turbo? have heard of these sucking closed, would explain the loss of turbo spool sound and so on

standard rubber air intake? Sorry but wats that? Everythings basically standard except K&N pod filter, EBC, BOV in the engine bay area. SO im assuming i do have the standard rubber air intake.

If this could cause the issues ive described, could you please help me out in more sense to myself plz?

the intake pipe (between the air flow meter and the inlet of the turbo) is fairley soft on a r34 gtt. sometimes when the car is under full load on boost it can suck the intake pipe shut, kinda like if u put your hand around it and sqeezed it together.

Most people go about fixing that problem by cutting the intake pipe in the middle and putting a metal joiner in it, or buy a aftermarket silicon intake pipe from just jap etc.

oh serious!? thanks heaps barney for the help~ so i guess its not the BOV after all...

Ill go about replacing the intake pipe to an aftermarket silicon then.
