100 octane gas
I'm wondering about the differences between the various 100 octane providers.
Around me are 2 100 octane providers at the pump.
One is Torco 100 octane the other is VP streetblaze 100.
Anyone have any experience with these two brands. More specifically, moving from Torco to VP what are the basic tuning changes that are recommended.
Btw torco is significantly less expensive than the VP streetblaze 100. I think the difference is about $1.50 a gallon.
I'm going to be switching to the VP streetblaze for a few months and see if I can tell any differene.

not sure what you mean ... are you asking if I get better gas mileage from 100 octane?
My car is tuned for 100(torco) so I don't run 91 at all anymore. It wouldn't be a fair comparison for me to compare the tune at 91 vs the tune at 100. Obviously the 100 makes more HP.
I will say that ever since I did the Supersprint Long tube headers, Supersprint Cats, Supersprint Xpipe I get much better gas milage. Why? Because the car is LOUD.

Just make sure it is unleaded. I just found a specialized gas company near my office complex and they sell VP unleaded racing gas.

i ran a little VP 100 from 76 stations and didnt notice anything funny. but my car was always dirty so i may have missed a little brown residue on the back.
brown/black stuff may just be a richer tune? i don't know what kind of AFRs they are shooting for with this car.
i can tell you for a fact that running 110 leaded will basically make your tail pipes look like they spray painted with primer. so i would assume that 'low lead' may look like a 'little primer'.

lead
E55Jay,
Make sure you are running the unleaded versions... even low lead is LEADED.
I'd just double check the places that you bought the fuel from previously and check ... if they were leaded then yeah cats most likely were damaged.
Ryan0,
yeah the code makes the car run pretty damn rich up high.

Been using VP 101/109 for a very long time now and never switching back to regular gas.
Used to run 91 but when i switched i did notice a hp increase. Car feels more responsive and crisp. I normally buy the 5gal VP 109's.

Guys, do a search for this, it's been discussed before. I've tried this with my E55 and documented it - ZERO HP gain, and the car actually runs worse on anything above ~93ish octane. The ECU mapping just does not give headroom for extra timing or anything above that octane, so it is a total waste.
Remember - the rule of thumb on octane is you want to use the LEAST amount of octane before the car detonates/preignites/etc - higher octane is harder to burn (ie, requires more ENERGY) and unless you can actually take advantage of it, will net LESS HP all factors BEING EQUAL.
Good luck,

Blackbenz you need to have Kleemann give you a 100 octane tune.

I wish we could get a flip switch tune for our cars. I dont want to run strictly race gas tune since I drive my car alot and dont want to get stranded and have to use 93 octane. How much did you gain with a tune?
10-17hp with 100 octane and regular tune? What if you use 108/110 unleaded?

It was around 15-20hp rwhp if I remember correctly. As to using 108/110 again it would have to be fine tuned for that. My understanding is that with 100 (at least the VP blend) is oxgenated so if you don't have knock at 100 it will produce more hp than at 110. I think at 110 you are talking about really super high compression or super high boost/nos.

I totally agree ... Renntech is working on a flip switch tune but it hasn't been released yet. I can't wait!

That is a significant increase! Hmmm, race gas tune, more boost, VRP cams (I will be posting how much power this makes on my CLK55 as soon as I install them), and lightwieght mods... watchout E55 guys!!!
Yea, well I use the 110 octane when I spray
