Hey guys. I was wondering what power gains i would get out of my LS1 after fitting 1.8 roller rockers? My cars got VCM suite tune, K&N intake, 3.7 diff gears, tri y's dual 2 1/2, and 2800 converter. it makes 308kw at the engine at the moment. thanks for the help guys.

I'm assuming you still have the standard camshaft. If so the average power gain is about 10%.
Cheers.
Mark.

Yes thats correct the internals are stock. 10% on what i've got sounds good. Would i be correct in saying that they would cost around the $800 mark. And would i need a re tune of the car to suit the new rockers? thanks again for the help

Hey vx300kw,
The YT 6646 1.8:1 Ultralite bolt ons are $863.35 inc gst.
Ecu does not require tuning after fitment of these.

Wouldn't it be better to get a touch up on a tune to get the most benefit out of the rockers once installed?

For sure.
Good gains in power, economy, and drivability can be had with the right tune.

is it worth doing with a larger cam??

as long as the overall lift doesn't compromise anything.
