been thinking about getting the meth/water system. But dunno, not enough people here have it at the moment.
man this system has been around since the hotrod guys, theres tons of guys using this in hondas,mitsubushis, v8s ect, its more popular in the us,Quote:

B) the car guys on this forum dont have it for 2 reasons.. 1 there cars are built by shops who dont put it in as it will cause problems wen the inexperienced ouner forgets to add water, or mixes water meth wrongly
or they see it as an anoying extra to fill the canister, or think its voodoo much like the misunderstood N20 cars
Quoted from the web page
BOOST SAFE!
All AEM Water/Methanol controllers include a Boost Safe feature. This feature allows users to retard timing or reduce boost via a ground output if the system runs out of fluid or detects a controller error, ensuring fail-safe operation of the engine whether the system is engaged or not. Critical safety features are integrated into the system to virtually eliminate any chance of failure, including an integral fluid level sensor in the reservoir, internal controller diagnostics and an LED dash light to warn of low fluid level or error codes (including short circuits.
Anyway im getting a little off topic.
i may not be 100% correct but this is what i have found whilst doing hours of reading and research and this is just the jyst i have come up with.
There is nothing wrong with boosting a High Compression motor and running low boost IF you have a good tuner. (i think ievaq8 and DL01 can attest?)
Lowering the Compression and upping the pressure instead does make power too, yes! (and lag) and now the car wont detonate as soon and the tuner will have more margin for error, hence less blow-up-ability.

he sugested i dont run over 8.2:1 or something with a turbo and lots of boost....
I laughed. then laughed some more ;)
speaking of comp ratios whats a stock integra VTiR comp ratio?
10.0:1Quote:

I disagree with that, the more you advance the timing the more the engine is working against itselfQuote:

I dont think this will ever be agreed on, as i just read all 15 pages and for the whole lot all the ppl with high comp engines say its the best idea because you dont get as much lag but all the low comp say yes bit more lag but safe.
I think its always goin to come down to what you want from your car,(my thoughts) if you want more of a N/A car with boost and dont care abt big numbers then high comp.
but if u like to boast abt ur car how it runs 1,000,000 psi and u have a turbo that resembles a black hole on your car and want massive numbers and dont care abt lag then low comp.
I personally am goin low comp as I have ERL building me a b16 race short block that is rated to 800hp and 40psi with 9:1comp and my logic is if you want response stay with N/A and that a honda engine has a massive rev range so unless your dragging off the lights or at the strip, just down shift.
I wouldn't class 9.1 as 'low compression'.
i have high comp and i still have lag.
Its just depends on how much of it you have
Of coarse youre going to have lag, its turbo'd and lag varies on its size and the engine capacity, what people are saying is that NA Honda motors and their high comp, dont have that piggish feeling down low like motors which are built for high psi and are low comp, causing them to be nearly useless off boost / down low.
High comp = more driveable / repsonive off boost
So for a daily / fun car, high comp low boost, you get best of both worlds, (ie: VW making their TSI (turbo superchatged injection) Polo, got the benefit of supercharger down low and turbo up high, to eliminate any 'flat' spots in its driveability.
Low comp = sluggish / boring imo off boost
Not as ideal for daily / will make big numbers
Thats the main thing you need to convey from all of this imo , alot of factors playing a role of how a car will be if turboed.
but which one off the two produce the most torque in specific to hondas?
Boost produces torque.
Low comp, More timing, more torque, more hp, more lag
hmmm its a real trade off really....
