Valve Management on the Diablo

Does all 5.7 Diablo's >98 have valve management and 530 HP? And is the difference between the 492HP and 530HP engine noticeable?

 

Also, I've seen a '97 SV for sale with 525HP, is this the stock power for the '97 SV? I thought it was 510HP until the '98 model...

 

Thanks :mrgreen:

Thats my understanding. In years prior the cars had differing HP ratings.

IMO, at some point in between a 5 and 10% power increase the difference can easily be felt.

Thats what I believe too.

Remember that with valve management, the difference in feel is not necessarily related just to the difference in peak power. I doubt many people could feel 38hp worth of difference in a Diablo, particularly in VTs with the higher driveline losses.

 

However, the VVT can make a big difference in the shape of the horsepower/torque curves for a motor. This means that a VVT car will usually have greater torque across a wider rev band. This you generally will feel more easily.

 

I can't find any pre- or post-VVT curves for the Diablo in my short search, but it would be interesting to see how the curves differ in shape with the valve management. Anyone got pre- and post- curves for the Diablo they can post?
