Race gas continued

[gasman]

I didn't want to start a new thread but I noticed no one was visiting our old thread. Please notice the last posting to include a web link for VP racing gas. The spec page addresses many of the questions posed over the months we debated that tired old thread. You will certainly appreciate the site if you had doubts there were benefits to using a higher octane product in a motor that can appreciate it.

Steve,

Thanks for the link. I haven't had time to look through it yet, but will (looks interesting).

Thanks again :D

I know, I know, this topic has been beat to death and then some, and yeah... the higher octane is a little spendy, but... my car runs sooooooooooo much better. The way these air/fuel breathing dragons, er... snakes are suppose to. I was out yesterday early AM and this morning again before it got hot, and man-o-man, with a 60/40 mix my motor is as happy as I am :D[^]:D

What kind of compression are you guys running that you need Racing Gas??

Mine runs about 9.9:1 or something like that. I filled mine with Union 76 100-octane once and it ran [u]awesome</u>. Haven't done it since. There's something about $3.99 a gallon that makes me wince. (My AOL instant messenger handle is CheapAssEngineer, if that gives you an idea.)

When the mechanic installed the new clutch he also adjusted the timing. Man, is my car running good now. My mileage also jumped from 5.2 MPG to 9.9 MPG. That's a 90% increase! And it runs better!

10:1 I don't necessarily "need" it....

Jerry:
I run only a/b 10.5:1 compression, and should not need race fuel, but
mine engine runs so much better with the 40% mix of 110 in with the 93 that I would never consider running 93 strait agian.

13.5 to 1 compression:D:D

If you do not have the compression to need Race gas but your cars run better with it, I would be working on carb jetting to get a leaner fuel / air ratio and then adjust the timing and spark advance to better burn the 93 oct premium fuel rather than just adding race gas.

the extra octane of race gas does make it easier to ignite (like a correct mixture) but it doesn't all burn if you don't have enough compression.

Rick with 13.5 probably needs at least 110 octane

Half to take 130 and add some Nitro for Brent

For those of you running high octane fuel, do you use any flexable fuel line from the tank to the steel line on the frame, or to the engine? Just regular rubber fuel line? Someone told me that 110 octane can eat through regular fuel line. Anyone know if this is true, what type of flexline can be used?

Thanks

From the hard line I have AN fittings and braided stainless on both ends. One to the fuel pump the other to a racing fuel filter, electric fuel pump, then to the hard line. Used all Aeroquip stuff, Russell or Earls is also good, 6AN size.

I ran braided Aeroquip from front to back. #8 from the tank to the pump, #8 from the pump to the regulator, and #6 from the regulator to the carb.

I ran braided fron the tank to the electric fuel pump; braided from the electric fuel pump to the hard line; then back from the where the headers exit the body ran braided and insulated to the mechanical fuel pump; and hard lines to the carb. I also have an inline filter before the electric fuel pump and a Fram fuel filter after the mechanical pump. Belt and suspenders!:D
