I have a 1989 camaro with a LQ9/4L60E with a TSP 224 cam, longtube headers and a LS1 intake.

How much power do you think I am leaving on the table with the ls1 intake, considering my cubes and after market cam?

 

Quite a bit...25-30whp could be easily had with a Ported Fast.

 

I have a ls6 on the way. I was hoping to pick up 30-40 just from the ls6

 

10-15 with the LS6

 

Yes 10-15 from the LS6 is about all you'll gain

 

10-15 with no heads? I would think 5-8

 

Yeah maybe. Hard to say really

 

Sell the LS1 on eBay. They command a better price on there. The LS6 I wouldn't even install. Either sell it here, or again on eBay.

Get you a ported Fast 92 if money is a concern. It rings in a bit cheaper than the 102 considering the extras you need with it.

 

The LS6 is a solid 8-10 whp gain on even a stock motor.

I agree. In the end Op will want a FAST anyway

 

A friend with a 228/228 cam in a ls1 picked up 2 tenths in the 1/8th DA corrected switching from ls1 intake to ls6 intake. He tracks his runs and DA religiously.

 

Looks like the LS6 intake is good for quite a bit.

Ls6 intake is good, Fast will still gain power even at stock HP levels

 

Like others have said, sell the LS1 intake on ebay and then try to find a deal on a FAST intake. A FAST 102mm sold the other day for $600 on FB.
