VP 100 aka Streetblaze, opinions wanted please

[kingsburgphil]

My local gas station pumps "streetblaze" @ $7.85 gal. Your thoughts regarding this 100 octane ethanol laced oxygen bearing gas in a hi comp NA motor
would be appreciated.  Please !!

[kingsburgphil]

Am I asking too much ?

[Rennsurfer]

I don't know much about Street Blaze... other than it's oxygenated with ethanol, unleaded, and doesn't have any metal compounds in it. Because of the lack of metal properties, it's safe for the newer cars with sensors, catalytic converters, etc. It's always been my understanding that the Street Blaze 100 was originally intended for turbo or super charged engines with higher compression ratios.

But to answer your query, Phil, I'd venture to guess that there are many other options in the way of race fuels for your car. If you're able, see if F&L Race Fuel is available in your area. Typically priced better and offers the same performance.

Hopefully, someone can give you more information for which you're looking.

Thank You..I was starting to think I was on the wrong forum. Later this year I want to "back down the squeeze" from 14:1 to maybe 11:1 and burn something
other than C 12. After being "held up by Ah poo" and paying $76.00 for 5 gals. of C12, I'm hoping others can share their experience with Streetblaze or an
alternative fuel.

P.S. I just checked out F & L fuels, there are three distributors in Fresno I'll be contacting. 

While on the subject of fuel/motor, what is a good starting point regarding initial timing and advance spring choice in a MSD dist?  Mine was "locked" @ 34 deg. and starting the engine was no fun.

 I chose the maximum initial retard bushing and two blue advance weight springs (completely out of ignorance,and a .89 4th.)

I "tried" it during the hot summer last year, just to see if it would make my 9.7:1 a little more forgiving after getting heat soaked slogging along in the 100+ heat. I run locked advance, total 29 deg, which, when I switched from large buffer (was @ 18 initial, with 1 light blue, 1 silver spring, 32 total) picked up throttle response and crispness that's hard to believe. But it has made the high load, low rpm, warm weather driving a bit tedious. I do have to be careful stabbing the throttles open under load at very low rpm or he'll ping. The VP 100 didn't alleviate this, but what did help (*but not cure*) this was making sure rollers and ramps on 48's accelerator pump cams were working with no slop and they fired instantly when throttles moved. I've seen guys' carbs where these were run dry and big flat spots develop and that delay would create some ping pong back there when they stomped it off idle.
Hope I didn't ramble too much.

Ramble on!   I consider the Lounge my new data base, and I need all the help I can get. Here's my thoughts, keep the fk 89, lower the compression, add a cooling system, retard the spark at low rpm, burn something like VP 100 and keep the 4:11, 2:46 1:58..0:89 4th.(3.88 axle). Our country roads run at 55-65 mph and freeways are 70+, so third is a bit low and fourth is a little tall for the country stuff.

The last thing I want to do is drop the compression to 8 -1 and put in a fk8, essentially cutting the balls off the motor and making a grocery getter out of it. I'd like to be able to keep most of the speed potential and be able to go further than just around the block. 

Please feel free to opine.

[Rennsurfer]

Please feel free to opine.

Alright... I'll opine.

Engine looks GREAT.

Thanks, other than the trans most of what I've done has been just "nibbling around the edges" and keeping it as I acquired it, a working racer.

Phil, mean looking setup. WOW.
Sounds like you like to use your car, like I do mine. Cool. I qestion how well the 0.89 4th and 3.88 r/p are going to get along with FK89, and your obviously generous ports. I think that combo may fight itself. I will post more thoughts later, but if you're keeping that gear stack, I'd swap cams so your power comes in in more of a "point and squirt" fashion and not in a "wait and see" way. I don't know all of your motor specs, though, so maybe I am in left field.
I think, depending on your CR, rod length, rockers, etc, maybe FK10 would be better.

I used 100LL from the airport and had excellent results from it for my 2180 turbo motor and the price is just about 75 cents to a buck over pump gas -- worked/ran like any 100 octane fuel

I just did a Wiki search on 100LL, and I like what I read. 100 octane, a little TEL and no goofy ethanol, just like the old days  .
I should be able to buy it in nearby Hanford for $4.20 a gal......things are looking up!

Nice looking motor- BTW, have you had any trouble with the coil mounted like that?? I thought the MSD coils had to be mounted vertically, with the leads at the bottom. I know of a few guys over here that have had them explode when mounted horizontally?

Thanks for the heads up, I checked the MSD website and you're correct. They recommend their coil be mounted upright, I will assume there are cooling issues.
For the time being I'll leave mine the way it is, because it's operating time is measured in minutes not hours.

When I install a cooling system, I'll come up with a different configuration.

One gallon of 110 leaded mixed with 3 gallons of 91 unleaded gives you 4 gallons of about 96 octane for about $4/gallon.
I'm not an AV gas fan, it was made for airplane engines.
I was told it was desinged for lower RPM aircraft engines, it may contain anti freeze qualities for use at high altitudes.

Lower Rpm but Higher compression and a lot of them are Turbocharged -- In the old days, When all the motors were ran on Leaded fuel (which was used as a Lubricant for the valves) Low Lead (LL) avi-gas got a bad rap because it didn't have the Lead for the valves. Now when all the engines are designed for and run Unleaded gas You actually get a little extra lubricant for your valves with the small amount of lead. And most prop private planes are not pressurised so don't operate at elevations/Heights that would require an antifreeze, and the ones that are pressurized have pre-heaters that warm the intakes.  I like it as a little extra insurance when I'm streeting my turbo engines (under limited boost) without buying the C16/C23 like I do when I'm racing. I ran the Fiat on it for 2 years of street driving with 10 lbs of boost and NEVER had any problems. Pinged only on the hottest of SoCal days under heavy load/boost
