Maximum allowable boost on the VNT1749VA

Thanks Sean,

Yeah I think we going to see how things go at around 1.6 bar boost.

If I may ask for your input regarding boost spikes - what factors play a roll in the size of the spikes - is there a way of minimising the size of the spikes?

No I am not Waynemods - LOL - just would like to understand the whole remapping as a whole (attach a link if its easier to read something)

Thanks

So - like stage one - Decat and SW?
x2 I also want to know.

cranking up the boost doesn't always make power. fueling is more important, I had a 1.6bar map spiking to 1.7bar and made 135kw. ive seen guys running 1.8bar maps but still can't break into 14's. Boost is important but not everything. their is alot more to consider and fine tune to utilise the boost factor correctly.

I did not refer to boost as 'everything' - was just seeing what kind of pressure the guys in JHB are running

what does that have to do with doing times?

What's the maximum "safe" level that i can increase the boost on my turbo? I'm currently running at 1.58 bar. Would 1.8 bar be too much?

All advice and suggestions welcome

Hi bud.
I have a AFN 1.9tdi but installed manual pump on it.
12mm head on tho.
Im getting close to 3.5bar boost but i have to check the egt when it starts boosting.

Yes buddy..
Its on original rods only piston upgrades.. And injectors.
Also changed manifolds to get rid of the extreme heat with the egt

Pics or it didn't happen

Perhaps your boost gauge is connected to one of the tyres?

Amazing what these relatively small turbos are capable of.

Also let us know how many km the turbo does until it explodes

Could you show us more pics of your set up also at 3 .5 bar? It sounds very very impressive.

doubt this as still no proof of this turbo doing 3.5 bar damn. eve. with pistons i would have rather upgraded the rods first as thats gone snap first under that load. also how is the headgasket holding that pressure (stock) boltd changed to arp but ya that would be something else.
