Discuss the Boost increase

[Sherwin@xcede]

Let's see the N54 experts out there. Voodo's car makes 50nm more than stock. What boost is it running?

 

[444YYY]

I'm no expert, but ... stock boost + 10%

 

[Scouse]

I say 0.7 bar if he is still stock

I like that graph:thumbsup: smooth and strong and no radical decline in Tq at 6000rpms:thumbsup:...i would guess 11 -12psi over stock & tune only with plenty more in reserve with mods?

 

[Sherwin@xcede]

Well I have a dyno in my possession of my 335 making 550NM on SNail's dyno. And the highest it ever made is 575NM. On the wheels. That was with hardware, meth & a lot of boost.

So we all know boost makes torque. A car making 550nm at Snail is boosting. 446Nm is not even 1 bar boost.

but is it faster then a 120d..... :shocked:

Just kidding dude... awesome gains there... Anything over 500Nm is just purely awesome :thumbsup:

Why the different Correction Factors.....lol (anyone hear that ? )

heheeh, I am still waiting for that one. But check this out. The stock run has MORE correction than the modded run. How you like them apples?

Next let's discuss the duration of the runs

No just kidding, some people were asking me what boost on Voodoo's car. I just said look at the torque, it will tell you the boost. It's around 1 bar max at peak.

1 bar boost seems about right, we have chipped quiet a few 135s over the past month, with similar power gains, we had a few from different tuning shops on our dyno as well and some of them are a bit down on kw and nm, but we have seen great gains from these engines ........still alot more power to be extracted from the car without playing with boost, these cars love high octane , on race days with proper fuel u can give it much more timing.....:thumb:
hopefully at the next event i can encourage a few customers to come to the track to guage against the competition cars.....
good work Sherwin, Kabirs car is certainly flying......:clap:

So what's the max boost you can go up to with s/w and std turbos if you've got all the boltons?
I know in the us they go up to 20psi and with upgraded turbos they do 22 - 23psi!!!
