What does one need to run a safe 91octane?

15psi or 17psi max with 23* of timing? (not sure what the corolation<sp> timing would have with that much pressure), but some have had that much timing on 91octane and still run strong.

Please educate me....unlike the old days with my Silver Termee, I havent been up to par.

with 91 octane i wouldnt run anymore then 21* of timing and some will say thats too much. 18*-19* is what my tunes are run off.

so other then a non whipple (ported eaton or just pullied eaton) a ramped to a total 23* is just fine? 18 ~ 19* doesnt sound like much though. I can totally tell the difference from 18 VS 23* and it shows when going up against some one with that much timing....but a whipple would be something difference, id imagine.

nope it doesnt matter. i say stay safe. ive burnt one piston already and i was running 93 octane back east.

Ouch!

Yeah, dont have that kind of cash to lay down on a new short block!

Some people have smoked the pistons on a stock 03-04 cobra due to tight wall clearance. It is all in what you want. My wife can tell yuou that my car is my baby. But I want more. This is a chance that I am taking. Right now I have 513 RWHP & 484 RWTQ. This was done with a Steg. Stage 4 port and 2.8 upper.

Also, NO matter what anybody tells you, IT IS IN THE TUNE. If your tune sucks, the you run the chance of blowing up your car. I went with another fellow 03 cobra owner to a dyno to get our a/f check and whe he found out his car made 40 RWHP less then mine he got a bit mad. We both had the same set-up's, but he lost the 40 in his side pipes.

He had the guy at the dyno mess with his tune and after he got it off the dyno, he could not start it. Then on the way home, the fan's quit working and it overheated. He kept having the problem until he had the computer replaced. But it all started when the guy at the dyno messed with his tune. You can ask U1arunit about this.

So if you are willing to take that chance, just make sure you have all the supporting mods and a GREAT TUNER. I have learned a lot by asking the guys have done the mods. This is how I make up my mind on what I want to do. If you are unsure, just ask before you do.

Just remeber, it is all in fun & there will always be someone faster then you. Jeff and Mark are faster then me, but I am playing catch-up.....

Do you have a Whipple?
91 with 15 PSI is 19 degrees
with 17 PSI 17 degrees.

Don't go above 17PSI with 91 octane

I just had MR Whipple out for a ride on 15PSI

Can't bump it to 17PSI on a race gas tune.

I don't read plugs I read the wideband.

No, if my Mach does leave the driveway, why not? My silver Termee stopped so short of anything respectable. Black Cars are fast !!

OK, but comparing 15psi on a whipple and an eaton...whipple just makes that much more efficient numbers down low, mid & top?

How is ur IAT2's with the whipple? I felt a KB with 17psi and it felt sweet! very torqueeeeh!! but other then a valve spring or possible scored block, she still ran 11.7's @ 105. dgussins old vert.

On my 2.76 ported Eaton I ran 20 degrees of timing.
I always run on the conservative side with 91 octane.
It is not worth playing with fire on this crappy gas.
I also have a winter and summer tune. My car leans out .5 on the A/F when the winter gas hits the pumps.
I plan to run the full 23 degrees on race gas and 17PSI on the Whipple.

[P Machy]

hum...

OK, so richer A/F if tuned in the summer season gas.

I hear ya on the conservitive side...just the air is so thin where I normally hang out, but I live closer to sea level.


MAF....

whats the MAX that a lightning housing & internals can hold power wise? I understand that a stock MAF is good till around 460 ~ 480(also dependent on air).
