    Default More boost

    If you are fitting a hybrid turbo as I have and wish to raise the boost above the 3 bar absolute limit, it can be done quite easily by fitting a third party 3.5 sensor. I used a Zeitronix MAP sensor good for 50psi absolute.

    Best to add the sensor and remap at the same time with a place that has an external pressure sensor, so you can ensure you don't over cook it.

    Yes but will it now do 1/4 mile in less than 15 seconds?

    My (very) old Honda CBR1000 will do it in less than 11, but that seems not to be the point of the excercise.

    I think with over 240bhp now I should be under 15 seconds.

    That's a serious amount of power. How much room is there left to play with if you have stock internals?

    Well that was on Friday when I was running the stock 3bar sensor at its max of 29psi relative. After fitting the 3.5bar sensor, I should be running about 34psi and need to get it back on the rollers to check the exact boost and what output it is making now as I have had to turn the methanol down alot in the peak torque reagion 2500-3000rpm to prevent clutch slip.

    Can you increase the boost on a standard vectra, and is it online done via a remap, the car already has a map.
