| but...I did mention to him to not lean on it like that all the time, and to learn to listen for pre-ignition. I set it like that to establish a boundary for him. "Here's the highest you can safely go". Not to mention, big boost on stock rings.... well... that's just a reliability issue: How long do you want your motor to last, even IF it's not detonating? Seb brings up a great point. Folks, do NOT try that at home without 555s, the proper ECU and using alcohol injection or an alcohol mix. I'm not sure about water only, I've never run it myself. Steve at SMC swears that an equal flow of water to the same flow of alcohol needed to protect your motor, will not protect it as well, and he's sold and tested thousands of kits, and had anecdotal info from boosted customers for several years. Even then, don't use the fun button on the controller all the time unless you are prepared to pay for disposable engines. And even if you're not detonating, listen for changes ever day, in case the air pressure or temp outside is different due to weather changes. With stock turbos, I have another customer with the 555s and the SMC system (not SMZ, sorry Ben :-) that boosts that high with no knock as well. Alcohol at those levels actually raises the octane high enough that other SMC customers are able to run the 110 octane chips on their Grand Nationals on pump piss. After reading the SCC article about octane boosters in a bottle, that is a larger margin of protection that octane boosters can offer. On stock injectors people are getting 15psi no problem. I have an older SMC setup with Skylines and 555s and boost 18psi every day (Cali 91 octane) on my Wiseco rebuild for 20K+ miles now, remembering that the compressors on the Skylines flow even more air. Without Alcohol, I definately knock. As for Ben's car, it was a privilege and a pleasure to work on it, and Ben's a dream customer!! :-) I will try to get the MWS-TV footage edited soon. BTW: Original NA = 0-60 in 7.5 seconds. TT = 0-60 in 4.9 (with the 26.6" oversize diameter tires!) and his car weighs 3400 lbs now.
