Does this only work on engines with boost or does it also work on NA engines with higher compression?

Call Rudy Tootie 1-302-367-4962 @ Ice and he'll answer any questions u got
ITS A SKATER NATION !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

We have only done extensive testing on super charged Marine engines.However in theory it does allow you to run more compression as well as more timing. So as an alternative to running race fuel it should work well in conjunction with 93 octane gasoline.

If your N/A engine is designed to run on pump gas, other than the ability to safely lean her out and add a taste of leed.
I don't believe you would see the noticeable gains that we net on blown applications.

So, what is the cost for a pair of these kits?

Uh oh, what are you planning on doin? Also, did you get my PM?

Yep, got it, thanks. For insurance purposes need to stay naturally aspirated. Been doing some research with my friends while they are working on the Toyota developement program for NASCAR. It will be down the road some, don't worry that you're BT won't be the fastest. I just want to break 100 NA.

Yes, very cool
