How Much Are You Boosting

[tgorman]

Thats a nice car with the same hybrid as mine.

thanks yeh was so nice i couldnt say no to buying it
how much are you boosting willy ?

 

[mrwookie]

Could log block 115 with Vag-Com which would show Spec vs Actual boost, would give you a true boost reading and therefore rules boost gauge out of the equation.

 

[jamiebennett81]

k03 hyrbid (stock internals)

boosts to 1.4bar
holds to 1.3bar at 7000rpm (well on VAG-COM it says "Actual Boost -2290" which I would say is near enough 1.3bar)

 

[DJ-LIAMC]

Im boosting 7psi holds all the way, Pathetic

 

[Rocky Rocastle]

Im boosting 7psi holds all the way, Pathetic

oh dear, someones on flop.

Mines now seeing a spike at 24psi and holding 20psi, much happier than the old 29/30psi

do you still have the tig art equal length manfiold fitted?

 

[Phillc]

Mines peaking at 20psi then holds 16-17psi.

 

[sparkyc]

same as above

I'm holding 1.35bar to the red line at the moment, the problem i have is that i can flow what i want at the red line but until i invest £500 in a custom remap i'm having problems limiting the boost spike 2500-3500rpm which causes me concern for my rods. I use a mbc for boost control.

 

[tripdiesel]

I peak at 28 PSI (1.8BAR) and hold just over 21PSI (just over 1.3 bar) at the redline, thats on a stock KO4 with remap

Post up some vagcom logs, boost gauges can be inaccurate. A stock k04 shouldn't be spiking to 1.8bar on a revo stage 1 remap.

mine done the same with the free trial.. only done it for the first 20 miles like then dropped to 20psi.
mine is getting mapped as i type so woo !!!

 

[BoomhaueR]

I get spike of 25psi then drops and holds 20psi. Aggressive stage 1 remap.

Mbc not smoothing the spike enough, Carl?

Its alot better than relying on the n75 valve but i can't set the mbc such that it will give me 1.4bar at red line and not exceed limit of map sensor during spool up. My ideal map would be 1.5bar peak tailing off to 1.4 bar at red line. Maybe a high flowing manifold will help with spiking as it will flow the turbine bottle neck a little better.

You ever thought about fitting an EBC carl? I've used a HKS EVC 6 on mine and its worked really well. Can set boost and duty cycle at different throttle positions and rpm's. Plus you can program two different maps e.g. for winter and summer.

 

[botanical_monk]

What boost should I be seeing on a standard 225?

 

[Ronin225]

Standard should spike to 15 and hold about 12-13 ish psi

 

[GREY 225]

Mines peaks at 1.7 bar and tails off to 1.2 at red line. Ive been told this is about the limit of the standard ko4 if you want it to be reliable.

mine peaks at 1.5bar and holds 1.2 bar
