Rocket Fuel

[Les Paul]

My '76 has all the goodies you can cram into a CIS system car. I had Imagine rebuild the engine nearly a year ago. I think I live in the only part of the world where not only can we not get decent gas 93 octane let alone 95 or 101. So yesterday I was finally able to buy 15 gallons of 101. I hauled it 200 miles home in 5 gallon containers Target has for 6 bucks. Wally world has the exact same item for 11. Anyway I overfilled and spilled a bit into my wifes new cars trunk before the trip home. I work at a chemical plant and that stuff smells like Benzene as I recall it. We phased it out 20+ years ago. It sure doesn't smell like gas.

So this morning my son and I blended in 5 gallons to 15 gallons that was in the tank. We went for a sprited ride on our little old 64 mile loop. We saw 3 oil field trucks in the first 28 miles. This is on an incredible newly paved FM road. Monster sweepers, 3-4 mile straights, perfect Sunday driving weather. Holding her at 3k rpms the punch was incredible with a stab at the pedal. That immediate blast with that little stab from 90 to 120 must be like crystal meth. Just a good day all in all. My son and I have been traversing this little secret highway since he was a toddler. He got to take the helm for only the second time ever. I think this was only the second time in 22 years I've been a passenger with a pilot that new how to take advantage of roads you can see forever on.

Sounds like good fun! Did you increase the boost at all?

[Les Paul]

I've got an Andial 1 bar spring. I've never seen it hit 1 bar but after my 3rd rebuild for various reasons I feel far safer at .9. I still have a factory 935 adjustable boost controller on a shelf in the garage but took it out years ago.

I'll probably keep blending till I get up to 95 or 96. There is probably a point of diminishing returns? According to the gas gauge we probably burned 5 gallons in that 64 mile jaunt. And it was worth every penny. Man I love that K-27HFS and the Fabspeed muffler. My son asked me before we left if I had fixed the stereo since the rebuild and I told him the symphony will soon answer your question. And it did.

Cool... I just ask because I've run 100 Octane fuel in my car and it never really *felt* faster at the same boost setting. The reason I tried it was because I wanted to run her up to 1.3-1.4bar whilst I was tuning my Apexi AVC-R. Once I got the EBC tuned to regulate a steady 1.25bar, I then went back to run 98 octane fuel.

So you have the FabSpeed muffler... nice! Is it the dual outlet muffler with the dedicated wastegate dump pipe?

[Les Paul]

That is the one. I've been on that 91 octane crapola so long I could feel the difference for sure. That Fabspeed is a quality piece of work.
