slightly off topic but possibly relevent..MarkB has deleted his 249N valve which i believe electronically restricts the DV's from working normally..?
he says he can now hear his valves working so i think it would be good to get some1 that has none OEM valves to try this to see if they work better like his 710's are..just a thought..

At what BHP do the 710N's become ineffective??

I've got Baileys.

I can't get over how well the car is running now, but I've done quite a few things to it recently. Each doing a little bit towards the better running

I've got Hyperboost HX standard size DVs, but with uprated Forge blue springs - serviced pretty regularly.

Have new 710Ns as well, and tried them on the car a couple of times, but i prefer the feel of the car with the Hyperboosts, especially on gear changes when on boost (mine seem to open smoothly and shut quickly) ... I also have the N249 delete ...

As an aside - i did some experimentation on the 710Ns by repeatedly pushing on the piston to open the valve and letting it snap shut - there were a few times when it didn't snap shut properly and stayed slightly open (the piston seemed to close at a slight angle - not flush with the valve aperture) - you could blow through the valve - in effect a boost leak! ... it would then close again properly after the next time it was pushed open.

When I repeated the experiment with the Hyper HX's they snapped completely shut every single time without exception, creating an air-tight seal (couldn't blow through the valve at all) - they also seemed to snap shut quicker than the 710Ns ...

Given the amount of times your DVs are opening and shutting during an average journey I thought i'd go with the HXs ...!

More expensive yes - but well worth it IMHO ... 8)

Forge on mine...dunno which ones though...they were on the car when I bought it. Reminds me, it must be time to replace the pistons and seals.

Worth keeping an eye on the vac pipe especially near the right hand dv (as you look at the engine) as its hard to route it so it doesnt rub on the throttle body and wear a little hole through it as mine did!
