I am switching intake manifold tomorrow and I got a manual boost controller on the way!

I don't know about the BP on 360 selling race gas but I believe Style's Buy Rite (right next to the BP) does.

Wow...I still run 87.

Why waste my money running higher octane when it doesn't help performance any?

Dublocivic

If I ran 87 octane my car would blow up. See with boost/high compression you need the stability of higher octane so that you do not get ping/knock (ignition of the air/fuel mixture before the piston is at the correct position to utilize the combustion of the two.)

With the factory ecu in my Talon it has a "knock sensor" screwed into the back of the block. When this sensor hears knock the ecu retards timing in-turn robbing me of power.
The higher octane raises the threshold of knock so that I can run more aggressive timing and boost without the ill effects of knock.

So there is a benefit of running higher octane when you enter high compression and or boost into the equation.

Welcome to the board nic!

I know...just making the point that my car doesn't run any faster with the higher octane than it does on the 87.

Dublocivic

Right on...
I was just making a point that on some cars octane makes a huge difference in performance when the car is tuned for it.

I'll check it out today...I goto the VACU bank @ genito/360 every now and then.

well nic, at only 10* of timing, you'll never run any better on racing fuel (fuggin white boyz geez!) lol

aed over on willis road sells race fuel. it's the purple shish (not the cheesy blue shish that orange market sells). im still debatin how long i wanna wait to put some of that in the 4pak thou lol
