Standard Turbo and Computer with a higher boost???

[CrazyMan]

if i may jump on the bandwagon here...

my r32 gtst is running 15psi, through a no-name bleed valve, (was running 17psi with no dramas) and i dont get any of the missing/hesitation that some ppl have mentioned... Does this mean my ecu has been re-mapped?

standard turbo (hiflowed)

How about setting the boost with the control arm to the wastegate and leaving it alone. Power is controlled by the right foot right ? Mine is set at 20psi and thats it. If its raining I don't nail it.

The only purpose I've seen so far for adjustable boost is so that when I beat a dude in a "traffic light grand prix" he can say "but I wasn't runniing full boost" or "I was only running 12psi" etc.

Oops, I can feel a flogging from Sydneykid coming

bleeders 'trick' the car into thinking it's still running 10psi while it's actually running, say, 12 etc....

That is exactly what a EBC does !!

It will bleed pressure out of the wastegate hose to increase boost, as well as (some do) stop any pressure going to the wastgate to eliminate wastegate creep.

Basically a EBC and a bleed both 'trick' the turbo/wastegate into generating more boost.

It's just that an EBC is usually more stable.

I know what it does. Just seems to me from reading above and elsewhere that people have no end of headaches setting up these systems, EBC and bleed valves. Doesn't seem worth the hastle to me, thats all.

yah dont bypass the boost solinoid it doesn't like it. I tryed on mine and the dyno said something like this. bypass boost solinoid: 10PSI. fuel mix, 10 (ritch). power, not even 110KW at wheel.

with boost connected: 7PSI fuel mix, 12 (just right). power over 120KW at wheel. if you guys dont belive me try it. dont think you got more power untill you put it on a dyno. I hate those !^#@$%( that think boost is everything that makes a car go quick and that's all you need.

This sounds like the answer i was looking for... are you saying i can have the standard wastegate adjusted for more boost? then the ecu remapped to suit?

Here here!

[GTRman1992]

Yep.

[DJ984]

WOOOHOOOO!!!

ok, now lets get technical...(not too technical though)...

I'm gonna have a dyno tune done in the upcoming months, can he do the retune on the ecu?

how do i adjust the wastegate (or how is it adjusted?)

No, on the contrary GTRman1992, if you read my past posts you would notice I agree with you. Multi stage boost controllers are a waste of money better spent on something that makes the car go faster, not slower. Like you, I use the throttle to control how fast I go. If I don't need full power, I don't push it down so far.

I'll get back to those turbos of yours in another post........

[GTRman1992]

Yes, I can name at least three dudes I know who installed a turbo smart bleed valve and blew up there cars. You cannot just wind up the boost without considering a lot of other parameters. Best to set the boost with proper tune and leave it alone.

I look forward to continued discussion re my setup.

And how do i adjust the wastegate to do this?

Put your car on the dyno before playing with the boost. Not only will you be able to determine exactly what boost pressure your running, but also determine other things like fuel pump health which is almost paramount.

bleeders sux and so does the single solenoid avc-r. Get yourself a dual solenoid ebc like a profc b spec 2

I could be wrong but dont most electronic boost controllers 'pulse' the signal hence making the top of a boost curve like a sine wave? A bleed valve just lets it flow with less turbulence?

I believe that BMT took the HKS EVC off the Endless R32 to make way for a $150 bleeder. This is a car capable of running 10s....

The only purpose I've seen so far for adjustable boost is so that when I beat a dude in a "traffic light grand prix" he can say "but I wasn't runniing full boost" or "I was only running 12psi" etc.

:werd: That, and its fun to flick the switch.
