New Corvette Engine Shatters Previous RPM Limit

[vetteheadracer]

GM engineers have achieved a feat many speculated was not possible. The new LS7 7.0-liter OHV (overhead valve) V-8 engine for the 2006 ZO6 Corvette will not only achieve 500 horsepower but will be capable of running up to 7100 rpm. The previous limit was 6600 rpm in the 6.0-liter LS2. With this new engine GM is showing multi-valve overhead cam performance is achievable with a two-valve cam-in-block engine. For the new ZO6, higher rpm allows the driver to remain in first gear to just over 60 mph, contributes to higher top speed and improves overall vehicle performance. The LS7 is one of the first automotive OHV production engines in the industry capable of over 7000 rpm. The new ZO6's sub four-second 0-60 mph time is achieved in part by the extended rpm range and the ability to remain in first gear past 60 mph. The over-190 top speed of the ZO6 is partially due to the speed capability of the engine.

That car is going to be just mind-bendingly fast!
There still doesn't seem to much C6 activity in UK although I saw a new Mustang on the road for the first time yesterday. C6 has just won another Road & Track sportscar comparison edging ahead of the Germans (on price). Looking forward to seeing some over here.

Timon has bought a C6 (importing it himself).

... and hearing it!!

My little 5.7L LT5 sounds quite nice at 7000rpm, but 7.0L has gotta sound fantastic!!

A major achievement and clearly GM new early on they had to reduce mass hence the titanium con rods and valves. I've got an engine on order already

boosted.
