Charlie,

Since your a friend I can tell you, I'm sure you won't pass it on to the others.

I'm running a little over 15 psi of boost at sea level, which seems to be a little over 12 psi at altitude.  I've de-tuned the engine some to reduce heat and knocks.  My peak rwhp was 531 rwph, but with the timing pulled back for "street" use, I'm getting 460-480 rwph with over 400 ft-lbs of torque from 3500-6000 rpm.  Would like to get it to 500 rwph with "safe" race tuning.

I sure hope they don't change the restrictions for methanol/water injection.  I had checked with Steve M. before installing the system (5 gallon fuel cell, pump, progressive controller (only on boost}, hoses and nozzles) a few years ago.  It boosts the octane rating to over 105, which allows for more timing and less knocks.  Now I'm running a 50/50 mix of water and methanol, that should reduce the chance of fire significantly.  Is there a mix ratio that would be specified?    Does that mean E85 would also be restricted (85% ethanol)?

 

Thanks,

George

Hi George,

 

I'm only the editor, not the authority, on the Rules, so I can't answer your questions.  However, the intent of the revisions in progress appears to be:

 

1. Allow more flexibility on fuels (e.g., diesel, hybrids, etc.) based on what the car manufacturers are offering in their vehicles

2. Restrict highly-pressurized fuel tanks like for nitrous and propane

3. Restrict fuels that burn with an invisible flame like alcohol

 

I hope your inputs will help in the Rules discussions currently underway. 

All the best,

 

Tom,

 

Thanks for the info. Just a few of thoughts:

 

It seems that number 1 is at odds with 2 and 3, as manufacturers are experimenting with E85 (alcohol), hydrogen (compress gas), natural gas (compress gas), etc.

 

It seems that battery powered vehicles can be susceptible to fires (ie. Fisker and Tesla). 

 

I've also read the methanol is soluble in water, and that ratios of 50/50 or less are non-flammable. Will the ratios be tested/measured at tech? 

 

In fact I can run just plain old water injection, how would this be verified?

 

Many windshield washing fluids are 50/50 mix of water/methanol, so would that be checked/restricted?

 

Thanks,

George

Hi George,

 

Thanks for the inputs - I'm sure the Board will find them helpful as they consider the 2014 Rules and review with the Board of Advisors.  Well, maybe the windshield washer fluid comments won't be quite as valuable...

 

but you guys who build your engines and run very high speeds are a great source of wisdom and important perspectives.  Plus you make me jealous.

Dave, nice to hear from you!  I'm just the editor (i.e., glorified spell checker), but so far there don't appear to be many changes at all - the biggest one being considered at this point seems to be on the fuel.  The Board is taking input from the Board of Advisors and is discussing things, and I expect the Board will soon turn me loose to create a draft of the 2014 Rules from their decisions. I don't know the exact timing, but the wheels are definitely turning.

George,

 

No, we do not have the facilities to test any fuel or injection fluids during tech inspection.  For that reason, as well as others, we will NOT permit any methanol injection, or any type of alcohol injection.  It doesn't matter what the mixture is - NO ALCOHOL or any other type of potentially flammable liquids will be permitted for supplementary injection systems.

 

If you have the apparatus for this injection system installed, you will need to disconnect it, and also prove that the injection tank is empty, if you want to compete in an SSCC event.

 

Water injection ONLY is permitted.  (And you might have to drink it to prove it is water!)  We had an incident previously with someone running methanol injection and I don't want a repeat of that incident.

 

Sorry for being the "Grinch" this time of year, but we need to draw the line at certain fuels and injection methods.

SSCC Chief of Tech

I can see issues with this rule.i remember when a big red brick ran ethonal. and with the e85 vehicles that came out very strong a few years ago,what is going to prevent them from running that fuel? esp since some of them are now tuning for e85 exclusively.I planned on converting the stang to e85 for the same reasons many of the High HP guys do, cheaper fuel 2.56 here and 105 octane.E85 is here and I don't see it going away like 100% gasoline is [which is what I am tuned for now]

I think the SSCC really needs to look at this and rethink their position.Stan 

 

PS I just read Steves post,again and it says injection I hope he is referring to additional nozzles and NOT the factory system.
