I am running 2000 Honda Civic Si cams with my cam settings at 0.

 

I make a measely 315whp on pump in my b16 because boost won't build anymore.

What happened to the "300whp is not attainable on pump gas in a b series" days?

 

anyone here using alcohol/water injection with pump gas? the car im working on now is getting a meth/water injection kit this weekend. gona see what we can do with that, pump gas and a sc61

 

I go to the airport in Louisiana and buy 100 octane unleaded for $2.59.

Alky/water is amazing! All I get is crappy 91 octane, I got the GT66's on last night straight pump gas I started getting some mild knock around 19 PSI. Spraying 50/50 distilled water/meth pump speed @ 10 dual M15 jets transitional controller starting to spray @ 8 psi with an SMC kit 22 PSI absolutely no knock, and at 22 PSI it is way too much power for E/T streets to take from a roll. I like it Now I just gotta try it on a honda!

 

who ever thought that washer fluid from Wal Mart would be the best thing to deter knock?!?!!

Eh pure meth works a lot better, windshield washer fluid has a lot of detergents and other stuff in it. It is amazing how well the stuff works though, look at supra guys running 26-27 pounds of boost safely on pump gas, it's getting nuts.

 

100 octane gas is 2.05/gallon in a couple spots in south florida.

true, but compare the prices...i'd stick with the washer fluid

 

How the heck does washer fluid deter knock? Are you guys kiddin me lol.

 

the washer fluid, blue stuff, from Wal-mart is a perfect 50/50 mix of alky/water

i don't know about all the detergents that dude said they had...cause we've been running it for a while...and haven't had problems with 24psi on 93 in a 2.0l LS (Speed Phreak)

i'm not saying he's wrong, just saying i'm not aware of any of it.

 

how do u exactly use that stuff? whats the mixture you use with gasoline? or just traight up use it with no gas?

 

you get an injection setup....and have a seperate resoviour

 

How much are these injection setups?

so basically like nitrous single fogger set up?

 

Alcohol/water injection systems do work at cooling down the combustion chamber, and in the event of alcohol injection carry alot of caloric value. The greater caloric value means more energy burned, more energy transfered onto the piston during the combustion event, and thus more power per pound of boost similar to race gas. The major downfall of the system is the inability to measure what level of alcohol you are injecting into the engine, as well as the uneven dispersion of the vapor. Not only do you not know if you are at a optimal level of injection, each cylinder will get a different amount of water/alcohol and make the combustion process uneven. This loads the bearings, rods, pistons, crank differently and can cause major issues if used for an extended period of time. So while the kits on the market do work, you have to think of them in a different perspective than what they are marketing them under. If you could inject the alcohol in an amount that could be calculated, and injected into each cylinder evenly the theory would work without flaw. This would require a fogger style system of injection similar to nitrous, or run a secondary set of injectors with its own fuel pump, tank and basic ems to fire the injector system.

 

Why not just run race gas when turning up the boost? That just seems soo much simpler and affective.

 

Exactly.

Are you gonna daily drive your car on race gas? I don't think so. Alcohol injection is MUCH cheaper in the long run, and is much more convenient, and helps keep combustion chambers clean by steam cleaning off carbon deposits. The pistons in my friends stock block GN with 110K miles on em look like brand new, with 11K miles of hard boosting 26 pounds daily on 93 octane + alky with a PT66.

 

Im guessing tonys timing maps were probably at 20-21. running less then that is just pointless. Most of the time. of course there are exceptions. CR and fuel are 2 factors and this car had 9:1 with 93 octane.....21 or so i think

 

No kit on the market allows for even dispersion of the alcohol into each cylinder. There are no intake manifolds on the market that can allow for even distribution (except possible the air research) of air/flow to each cylinder, so at best you are going to have different percentages into each cylinder, #1 cylinder being the worst case scenario.

 

well, no meth yet, it hasnt come in ... but we were running around on 22psi wiht 93 yesterday. ran great.. then we acidently hit about 35ish.. guage max's at 30... when the vac line on the wastegate came off... spinnin through 4th on the highway is awesome.. i wasnt logging at the time but i have the cel set as an afr warning at 12.8;1 under boost and it never came on and it pulled smooth as hell.. but we wont be doing that again. the meth should be here this week and we will go play with it friday night

 

If tuned properly you can easily have 400whp or more on pump gas even with a slightly agressive tune. Why would you need more than that? When you get to the track then turn up the boost and run some 112 or whatever. Better than risking your motor on something that may provide you with insufficient distrubution. That's just my thought. Spend the money on something else. Larger Turbo, tuning or whatever ya know.

 

bringing this thread from the dead, but I would like to know if anyone has passed the 600 whp on pump gas mark.

most I made on 92 octane pump gas from 76 station, was 575 whp and 403 wtq at 25 psi boost.

 

404 whp with 91 octane on 14 psi pt67
