Vp c-44
 

I sent Bob Blackwell (D5 Technical Department) an email asking him why VP's C-44 fuel is not on the Accepted Fuels List. VP has told me on two different occations that it is a non-oxygenated fuel, but NHRA blacklisted it years ago. Upon questioning NHRA, Bob said he forwarded my email to Jim Collins for further review. Jim is the guy who developed the fuel testing system for NHRA. Bob told me that C-44 has "oxygenating properties", but would be looked into again to verify.

I haven't heard anything as of yet. It's only been a couple of weeks, and Jim has been away from home. So now I'm curious if anyone has any experience with C-44, or knows anything about it. We wanted to try it on the dyno soon for comparison purposes, but if it's illegal, we'll stick with C-11.

Anyone have any thoughts??

I saw some turn red and blow out of a test tube at Indy several years ago. It's worth HP but they will never approve it. Stick to the C-25 or 11.

Mike , have you check the price? I didnt and bought a 55 gal drum and was a little shocked when I picked it up. $1300. 5 years ago ! I did dyno and use it . It's worth .05-.08 but no way will they ever accept it again. It evaporates like crazy, if you put some in bowl and put it out in the open , it is gone in seconds . All thats left is a lot of water droplets and it evaporates so fast the bowl turns cold! Bob

Wow! Thanks gentlemen. Now my question turns to why VP still markets it as a Super Stock fuel. That makes no sense, and misleading.

Dad and I thought it might be worth trying, but it sounds a little like rocket fuel! I appreciate the information. We'll stick with good 'ol C-11!!!!

Bye the way, is this the same fuel that would burn with a sweet smell? I remember several years back smelling something like that in the staging lanes and thinking "What the _____??!!

This stuff (44-46) would burn the hide off a moose at 500 yards.

That's the answer, Bruce! Marketing added an extra letter "H" to the acronym NRA. They're selling this stuff to the wrong association!

Mike,
That's a good one!

Re: Vp c-44
 

is c11 worth anything over c10

Re: Vp c-44
 

Not for me also C10 is unleaded.

Re: Vp c-44
 

Right. C-10 is unleaded, so unless you put hardened valve seats in the heads, you'd be asking for a lot of trouble! Like micro-welding the valves/seats. Also, replacing the seats to run unleaded fuels just makes for the possibility of the seats coming loose and causing another big headache. Leaded fuel is the way to go, and until the government says otherwise, we'll leave the unleaded fuels, like C-10, for someone that doesn't BEAT the valve seats nearly as hard as we do!!

Re: Vp c-44
 

How does C11 compare to C12?

I use C12 but not in SS

Re: Vp c-44
 

C-11 is a more application specific blend. Works better in lower compression applications with restrictions in air flow. I know a lot of stockers that use it with small blocks and big blocks, as well as super stockers. It burns more efficiently than C-12 and generally makes more power, overall. But I'm sure people have experienced different results. That's just what has worked for us with our 327 in super stock.

Thanks for the info
