synergy 2

[mark d3]

what bhp can i expect from a synergy 2 on a cdt? its £179 inc is it safe to put on a 92,000 mile engine i am looking for a bit quicker acceleration

If you have the 131BHP engine should go to the 150BHP mark but ensure the MAF is in spec and working and recommend Air Intake Mod and clean Air filter to assist the added air input required.
You will notice the extra Torque which helps prevent down changes thus giving you better MPG
but if you put your foot down plenty of power there.

The 116BHP engine will go up the same proportionally.

Mines running fine on a 178,000 mile engine.

I know lots of peeps have done it, but is there any actual evidence that the "air intake mod" actually does anything?

Its an easy DIY, but personally I have yet to see any sort of test results? Are there any?

Yes my rolling Road figures and graphs with it being swapped backwards and forward showed between -4 and -7 BHP difference.
I believe Rover Ron found similar also.
It would also appear to make the acceleration marginally better to. (Having the Mod done that is)
Having a spare obviously helps, the MK2 intake also prevents the problem of wet MAF failure etc.
Bear in mind this was on my own car and cannot show or state across the range of Mods on other cars as only tested mine.

Interesting... Thanks for the info John.

i think this would be a good mod for mine then was considering changing it for another 75 after owning for 2 years,various things, scratches dent in roof,water ingress under seats and the front end damage that i am still struggling to get panels in the right colour for but its never broken down so i am keeping it and spending some cash on it and my sister is plaugeing me to get it looking nice again for her wedding it could do with quicker acceleration so the synergy sounds ideal

The difference was tested on my previous manual 75 at a local rolling road in Shifnal.

Allowing for all other things being constant, refitting a full inlet tract reduced BHP over a fully cut back inlet tract an average of 4.6 BHP (ATW) over a total of five power runs in each condition. Peak difference was 7.4 BHP (ATW).

Power runs were carried out in each condition, back to back, such that any change in underbonnet temperature affected each pair of power runs by the same amount.

I can't remember whether there was much change in torque Maybe I ought to try it again with VeeKay.

Unfortunately, I no longer have the graphs so you'll just have to believe me

Very similar to differences I had stated in post earlier Paul.
