3 failures too many..and those are the ones that have been reported. Also do you know what's going with the engine internals on all the other meth users..no..any time u use meth or NOS...its a risk w potential for engine damage..and for what?.. to grab some extra power at the top end?..the benefits just dont out weigh the risk..my two cents

Blaming the 3 failures on meth is scapegoating. The history of meth goes back to world war 2, formula one cars, and world rally cars. So people please stop blaming meth for these failures. It has such a small part to play in the larger picture. Those that take forum speak for gospel might buy into the misinformation and spread it as truth themselves as apposed to doing some reading. Off The forums of course.

Now if you wanna adopt that philosphy for a street car...fine.. all I'm sayin is using meth on the street is not without risk b/c you have to maintain close control over meth flow, have fail safes and constantly monitor and log whats going with an engine... I have no idea if meth is soley to blame for these failures but isnt it a plausible theory that it contributed to them along with the ridculously high boost? I stand by my original statement...the risk of engine damage do not out weigh the benefits of grabing an extra 20 hp..there is a point where moding these cars gives dimnishing returns. |

There are people here with years of methanol use without a problem. Ive seen more failures on bolt on Honda engines then on this car, so 3 is hardly anything to cry home about. |

Cards on the table ..everyone knows meth is used vs running higher octane fuel b/c its MUCH CHEAPER..period. You have to maintain close control over meth flow, have fail safes and constantly monitor and log whats going with an engine, b/c its an external power adder..you need to maintain MUCH more control over whats happening w its flow and marrying that to the boost being run..Using higher octane fuel your are not introducing anything externally..u put 100 octane you have an anti-knock index of 100. It is consistent and as long as you don't run excessive boost its safer. I agree using race fuel doesn't mean you should being boosting to 18+ psi.. I will concede your point about meth signifcantly cooling IATs, there is no arguing that. But again other safer ways, larger intercoolers, CAIs, ducting etc. One of the vendors on here said it best..what levels of power do people expect out of these engines before there are consequences...there is a limit to everything. |

By your logic, only methanol is to blame for engine failures. The truth is, you could grenade a motor at 15psi on pump gas (which isn't over-the-top) as evidenced by a customer who did so back years ago on the original Procede rev.1. And to be fair, the OP who had the engine failure in this thread had his failsafe disconnected and was running on a JB3 which did not have this progressive methanol feature which the latest JB tune and Procede have. I would encourage you to do some more research before blindly attributing the engine failure to methanol itself.

Oh i agree, meth by itself is not to blame. Its more the mentality that some that you can simply keep modding and extracting power outta of these engines w/o consquence. But given that these cars are just about 4 years old, and meth use on them really didnt get going till say 2 years ago? I think its premature to determine whats safe for these cars, never mind Hondas. |

And FWIW, I have an aftermarket FMIC, downpipes, intake, along with methanol injection. The only thing I'm missing is the exhaust, which doesn't add much if anything.

Methanol isnt for amateurs either, and 600WHP on pump gas with a big turbo can be just as risky for the motor when we dont know its limits. (using arbitrary numbers here). Point is, live and learn, and have fun. As long as nobody gets hurts, its just a motor. If money can fix something, then thats good enough. Gotta pay to play. Want to live in fear of blowing something. Keep the car stock. No guarantees in this business. |

Ok man, like i said in my earlier posts to each their own..but I feel I need to speak my opinion especially for the folks on here that are just under way with their modding. You want to me say that running meth is as safe as running higher octane fuel..absolutely not..can you get more power and lower IATs w meth absolutely yes..but to what end? |

Absolutely, and thats really all I am trying to say here is that you can reach a nice respectable 380-400 whp and ft/lbs of torque without meth. |

And you can maintain those numbers if the meth kit ever took a dump. That's the whole point.

race gas, menthanol injection, nitrous oxide are truly legitimate power adders -- i dont think that there is any debate to that end...
but i would like to add this as an engine builder (in the past tence) -- i would never ever recommend a guy use any of the above options unless he was willing to face the consequences -- good or bad! especially for those who are new to the horsepower game. taking a lot chances and relying on technology to support your practial knowledge is a bad combination. if youve become familiar with engine operation, and limits (yes limits) you can find a successful road to more and more horsepower. remember the old adage-- Rome was not built in a day!! the preplexing thing about modding your car is this -- are you an owner or not? if you plan to keep the car, mod that thing into the ground. but if youre not, you may wanna consider the aftermath that may lay in the hands of an ususpecting 2nd owner. i know this sounds like a buzz-kill to those on a "mod-high" -- but its food for thought |
