Not bad. I think the Vararam is probably the most popular right now. Although if the Orssom was cheaper and easier to find, it would probably be the better choice because of its "OE" look.

What is th real gains with these?

One said 10 to 18 rwhp and the other said 18 to 20 rwhp?

I know the LS1 woke up with a new air intake and K&N filter to 20 to 25 HP with Independent shops confirming it.

Since the L76 is alot like the LS1 I am assuming it has the same potential with modifications.

You are comparing the Roto fab G8 V8 to the Roto fab V6.

http://www.exoticperformanceplus.com/performance_parts/index.html?item=1462 V8 is listed at 18 to 20 rwhp increase.

http://www.exoticperformanceplus.com/performance_parts/index.html?item=1988 V6 is listed at 10 to 18 rwhp increase.


With the much better breathing heads found on the 6.2 engine, even more hp should be able to be found with aftermarket induction systems than on the older LS1 engines. The only way I can see that this would not be true is if the oem systems are much better than they use to be, and I doubt they are, as the oem systems are always having to silence the airflow to keep them fairly quiet.

Thanks for the clarification Bob.

I think an air intake would definately be a inexpensive for HP gains without voiding a warranty.

You're welcome, yes it is a quick and easy way to pick some extra power. Bob
