Will 100 octane be enough?

[NEARING]

Or should it be?
I want to run 22 psi this weekend and don't want to mess with the alky.
I can run 18psi on 93, well in this heat maybe 17.
Wouldn't too much octane for my needs slow me down? Or not?
I would like to get thrown out (too fast) before going to the Gulf!
Thanks.

You can always try it and see. If you get knock just back the boost down or drop a couple of degrees in timing and try again.

or....get the best gas you can and tune the car to run on it....octane will not slow you down........I didn't see what chip you are running.....some fuels can impact your spoolup if not accounted for

I have a Fel-Pro, last week my spool up sucked on the alky.
If I wasn't leaving I would play with the alky more.

If I can't have too much octane maybe I will just get some good stuff. C-16!

 

[azgn]

well, with the fel-pro, make your spoolup fuel really lean and you will go good!

 

[azgn]

on second thought, why in the world would you run anything but 116? you got a 10 sec build if I ever saw one! go for it!

Thanks, something for me to think about!
What would your car run at an east coast track?
10.50'S?

 

[azgn]

my times correct to 10.70's....I run 23 lbs boost and 1490 egt's....so, there is some left in it.....ya might say

I would kill for some 40* air and a good track!!

If you ran that time and MPH at 18 psi you should be ok for 10s with the C-16 and more boost . I ran 27psi on stock gaskets with ARP bolts on one side and stock bolts on the other side ( dont ask) if you run like 23-24 you could be into 10s why not be brave 25 The 27psi run didnt pick up my car much at all but with a TA49 and stock I.C thats getting out of range for those pieces

I wouldn't try running much boost with this heat.
C-16 may be too much it you decide to run low boost though.

IMO, you should never run anything bellow C-12.
