Also, I'm wondering if the JIC strut bar might work with the hood and the 5/16" spacer. The JIC struts seem to be a bit flatter than the stock bar, perhaps it would fit...

I did a search but couldn't find any information on 5/16" strutbar spacers with the hoods. Where did you find it?

Most of the gains come within the first 1/4". And there are rapidly diminishing returns beyond 1/4".
The 1/2" does provide higher peak numbers, but only by about 1 to 1.5 HP. With either spacer, you will be much better off than stock.

Well I would be happy to do before and after dynos. I will talk to Turbonetics as my car should be back up there soon and see if they are willing to do before and afters for me. FYI they have a Dynapack dyno there.

I'm making preparations for the GB now. There is always a ton of work involved with doing a GB. I had to limit the last GB to 100 units because the work load is so huge.
I don't expect this one to go to 100 but I still want to be prepared.

Wow I'm so glad I live in CA and don't have to worry about it. It was a fun read and I learned some stuff though...
Will The Motordyne XL STB and Hood spacer kit is $40 work with the new spacer and stock strut bar?
OK any of you out there that have the 1/2 spacer with the hood modification, please tell me how you like it. Does the hood still function the same? Pros and Cons besides everyone telling me my hood is open???

I know 1/2" fit under Zboys vented carbon hood.
