Wow, that thing runs like it's on the bottle. 200+lb camera, too!

Sick!! Do you know what the car runs on 91-93. Just trying to figure out how many tenths or mph a race gas tune is worth. Thaks

On stock boost, not that much...just more timing and knock prevention...Obviously, race gas would allow you to run a lot more boost safely and that is what will give you the big increase in hp...

sircl55amg

the best i did on 94oct is 12.20@117mph

Better timing and det protection even on stock engine. Funny you don't hear any "tabarnac" or "calice" in the videos , miss hearing that lol

sircl55amg

ha ha !!! .. that happens more when i lose !!!

Hulk

lol...good times

Great runs! Race gas like MS109 or something comparable works great on stock 55's. From my experience, I would say it helps substantially.

sircl55amg

yes i was on vp ms109 last year and it was very good...this year i switched to panta and same great result for a better price

Yes it works great on these motors and is oxygenated but you must be tuned for it since the stoich is different than 93

I have a station 5 miles away that pumps 100 octane Sunoco. (you can drive right up to the pump).
Outta curiosity, I'm gonna try a logged blast on the same day with same conditions and see how much timing advance I get with the 100.
Run 100 or 116 in my race car...just the smell of that stuff makes me smile.

Nice! Az reppn! I gotta get my to the track soon also.

Georgee6086

So you went from 12.20 on 94 to 11.65 on 108 ( same 60's?)

Hulk

Also, amb temps would make a difference

sircl55amg

about the same 60' 1.7 1.8 yes ambien makes difference.

at 25celcius amb i did 11.705 @ 119.40 and at 15 celcius amb i did 11.653@120.71

same race gas about same 60'


but you need a tune for race gas ... if not it will make no difference


now in mid summer ... at the end of the pull my IAT reach 45 celcius .. so the timing get pull a bit

SO NASTY!

You see what 105 race-gas can do - imagine what meth will do with the added cooling bonus.
