Shell URT 110 Octane

Anybody use this on their 996TT? Do you run it at higher boost than VP109 or Sunoco GT Plus.

Thanks

URT = Unleaded Racing Techology

It is supposedly better than c16 (in some testing) and you don't have to worry about your 02 sensors.

Hyperfuels now sells it. I am going to pick up some on Thursday or Friday Mike. I just got my car back after having the engine built to 3.8 so looking forward to turning up the boost. I kept the Alpha 28s and got rid of a few mods actually lol, now I only have the built tip, aftermarket injectors/added fuel pump, gt2rs intercoolers, markski exhaust and oem-style intake. I got rid of the agency y-pipe, tb and plenum.

you should be able to run a few higher psi with 100 octane versus 93. Many people run 1.5-1.6 bar on 104-105 octane race gas.

Anxious to hear what you think Ben!

Very interested in how your new mods work out too!!

Thanks but I dont plan changing any thing..Just wanted to see if I did notice a difference with my tune and at 1.3/1.4 bar,which I did.
Todd said that I was at the edge now with 93 oct and without that extra pump i couldnt have what I got now..
I am happy ,,, except I am still debating on trying that 74TB and modified stock Y-pipe to match it...LOL..

I just did a bunch of reading up on it online and people seem to LOVE this stuff!

Now to see how hard it would be to come by in the Northern VA area...

Looks like a good alternative to MS109. I made my 868rwhp on a stock motor using MS109 vs C16/Q16. Simple reason was longevity of plugs, o2s, etc.

I do not understand (even after reading the thread you did) that it was better than C16. The advantage of C16 is for margin of error, aka boost spike in the cold, someone screwing with boost controller, etc. It is a colder burning fuel than this which is why it is usually picked for use even over MS109. The setup on that Ford GT is fairly simple and making the same power on both fuels isn't a big deal. Now if they went head to head and upped the boost and see which one knocks first that would be the true test.

On a built motor, etc... the last thing I'd worry about is longevity of the cheapest and simplest fixed parts.

Personally if they have problems with pinging on C16 @ 980hp I'd have some def. questions that just throwing some magical fuel at it fixed the solution. Notice how second thread he also advertises to buy it now! Hmmm...

Haha, oh I don't doubt that they gonna push it a little since it will take a lot of marketing and fairy dust to knock VP off their stand... but in the end, if the numbers and facts are true 110octane, no oxygen, no lead, etc... then it sounds like they have a damn fine product on their hands. I'd love to test some out just to see how orange in color it really is!

And the only thing I've ever put in my car other than shell 93 at the pump, is a 5 gal jug of MS109 at almost $80... Options are good for the game, yes?

And who knows, maybe a few gallons of this stuff in your car will squeeze out a nice average between 109 and E85??

It's prolly nowhere to be found in VA though... I'm checking on that right now.

I don't doubt it's going to be a good fuel. I was a strong supporter of MS109, but my only argument was how people (not Ben aka Bad107) on other forums are selling it as just as good as C16. It's good to see some options to hopefully bring down price period of race gas.

I run E85 (I have the little tester to make sure its 85% Ethanol LOL) and race gas choice was C23 due to the slower burning, etc. The power gain vs drivability on C23 vs E85 def. favors E85 for my choice even if power is 100rwhp. I now have a 1.06 a/r hot side and added an IPD/TB to my setup may cause me try C23 again and see what these turbos really max out at with the good hot side.

Feb 2012 - Global Motorsports Group (GMG) has established a relationship with Shell Racing Solutions to be a Shell Unleaded Racing Technology (URT) Fuel supplier to racers and track customers in Southern California.

Shell’s new URT unleaded race fuel will also be the exclusive fuel used by GMG Racing for testing purposes on the company’s in-house dynamometer test cell. GMG will also use Shell Racing fuels for the company’s racing program whenever a specific fuel is not required by a sanctioning body.

“Shell is our recommended fuel for maximum performance applications as it pertains to performance-tuned road cars such as Porsche and Audi plus for testing all our World Challenge line of street cars,” stated James Sofronas, president and co-founder of GMG.

”Our hands-on experience in the field from race to road cars will show the technology being used and proven in all environments,” added Fabryce Kutyba, vice president and co-founder of GMG.

GMG now has Shell Racing fuels available to customers in Southern California. Shell’s new URT unleaded race fuel achieves superior results to existing leaded and unleaded race fuels without the use of lead. Race fuel technology requires extensive research and development expertise, the kind found at Shell Racing Solutions. There are about 200 constituent parts in a fuel recipe. Some are adapted specifically for the extremes of motorsports racing, because refinements that would not matter to a street car can be vital in racing.

GMG Racing was identified as one of the nation’s top performance dyno shops and invited to become wholesale direct dealers of the best unleaded racing fuel available.

GMG is North America’s premier Porsche tuner located in Southern California and specializes in Porsche performance tuning for road cars and is also one of the top Professional teams racing Porsche cars in North America. For more information, visit www.GMGracing.com.
