I think you will also find little diff in TQ between 10.8 and 11.8 , I have a car on the dyno now and will post the AF at diff places when I get back from tuning in NJ next week

But like you said if its working for then have at it , None of whats been said in the articals was directed at you

Its pretty common practice for the honda big boys, making 800whp+, to run 13.5:1 AFRs. These cars have 10:1 or 11:1+ CRs and are running low 9s in the 1/4. No one is saying it will last for ever that way, but to say 12.0 is unsafe, is an outrageous and totally bogus claim. I have personally seen a 20whp gain on a 300whp car going from 10.5 to 11.8:1.

Thats great , If you want your Focus tuned to 11.8 to 13.1 please have at it , My Customers (I am talking Focus here ) will not be pushed to those limits for a small gain of 20HP , if they need 20HP more 1-1.5psi more boost and keeping the 10.8 WILL last for ever and I think thats what most people want is safety and an engine that will last and I have a history of being able to offer that

Sometimes you just cant up the boost, you may be at the end of what the turbo has to offer.

No engine will last forever, especially when running 350whp+. Didn't Chris Krabb loose his engine less than 1 week after you tuned it? Not trying to bash, just saying no tune or method of tuning is perfect, and you cant say it is safe just because you tune rich.

Can I say it will last for ever NO ,no one can , Can I say that 10.8 is safer then 11.6 with little to no loss in power YES 100% I can say that and I dont tune rich I tune SAFE

I have customers from 2003 that are 300-350 and still running the same engine , I am one of them with just over 10,000 miles on just track time on the stock origional engine at over 320HP

I think one of the biggest things for everyone to keep in mind is just because Top Speed runs over 13:1 on their Turbo cars doesnt mean you can just get out your ProRacer and start leaning your setup out without having to readjust anything else.

Your setup may not run that lean safely or it may do just fine but you still need to do more than just lean it out, you still have to deal with timing, egts, ect....

You make it sound like TS runs every car they tune that way. I would assume that they tune the car #1 to what the customer wants and #2 to their set up and what they are using it for.

I have actually ran my Acura @ 13.5:1 and 26degrees of timing at 540whp many many times...that's 111 octane of coarse.

To each his own.

Dont try to twist my post around and make it seem like I'm accusing anyone of anything.....

Theres already been several people on here say that they were going to lean out their setups because Top Speed runs their cars leaner (including personal cars) What I said was you cant just go in and start leaning them out with out making other changes as well. You still have to take care when adjusting your AFR.

Also some builds may not tolerate going leaner and others will do fine, there are so many variables with each individual build that no two cars will be the same when it comes to tuning.

Yeah, I said I would tune leaner, but I'm also running meth. Don't worry about me, John

Running meth is no reason to go leaner even if your running 100% meth (I am guessing your talking WMI) or should you run more timing but thats a whole nother discussion
