Before and After Meth results.

[Zach Holt]

Before, slow. After, Go.

[Dan Harshey]

Dan - How much power are you making with your setup?

I made 248hp and 232ft/lb on RG dyno, i was at that time running a chipped eprom with SAFC for tuning.  Stock 6 Bolt, with balance shafts removed.  FMIC, 750cc injectors, 255HP Walbro, and the GT30-10, at around 19psi with 400ish cc's of meth post turbo.  I believe the SAFC and chipped eprom were holding the car back, i was having some issues with the chip that was burnt for the car.  
I've since changed to ECMLink, dropped in a set of cams, and put on a FP Race Manifold, i'm curious to see what it will put down now.

[Jordan Kruger]

Nice. keep me posted. Did you buy the garret brand new? Reason I ask i because I just bought the cartridge and used my original cold and hot side, And it still came to $1100   yikes. Im just curious what you paid. As for the car, Take it to RG if you ever get the chance. They ironed out my low end so the car is quite driveable and spools relatively quick now. Before that I had slight bogging problems.

[John Hartman]

Cam, do you have a check valve in line, just before the nozzle?  And do you have a solenoid or are you just activating the pump?

I find VERY little lag in my system.  It sprays within miliseconds of the boost switch activating

Jordan, thats a good deal for those turbos.  They were $1500 USD new a few years back.  I used to have a -10 and now have a -12.

If someone dosnt post a pic of a befor and after meth results from google images I wil lol :p

[kevin derhouson]

meth = good nuff said.

I gained about 40hp and 35ft/lb by having the car tuned properly for the meth.

I'm running 20psi, with a GT30-10 turbo.  Also running a fairly small nozzle, a D05 which is around 400ishcc, before the throttle body.
For a comparison, when dyno tuning we went up one nozzle size and i gained 14hp.

I'd almost consider going with the progressive kit now, but didn't have the coin at the time.
P.S. i'm also running 100% Meth

Tuning without meth is mainly for low boost <15 psi... even then you have little margin of safety.
If you can't afford the meth ...drive a stocker and leave it that way and don't complain about bogging ,hesitation, sludge buildup, going up hills or high elevation driving.

Most dyno customers are so disappointed in their results they often install the meth kit immediately.

[John Hartman]

all that said, there were good numbers produced before the masses used methanol/water 

Most of that was on race fuel tho, so if you want a fast pump gas car, you almost have to use methanol/water injection.

[Brett Haviland]

or put a 4g63 in a way lighter car then a heavy ass awd dsm!!

[John Hartman]

and spin on the hiway 

[Brett Haviland]

huh??  i dont know what your talking about

[CamWeiss]

Cam, do you have a check valve in line, just before the nozzle?  And do you have a solenoid or are you just activating the pump?

Yes to the check valve, it's correctly placed too. The boost controller activates the pump via a relay.

[John Hartman]

ahh, ok.

Get a solenoid.  Run the methanol to the solenoid from the pump.  Then solenoid out to the check valve, then the nozzle.  This way the pump keeps lots of pressure in the solenoid.  The solenoid is also much faster acting.  The pump takes a couple of seconds to build pressure, whereas the solenoid is nearly instantaneous in release.

Have whatever you use now to activate the solenoid.

[Vlad Busta]

I have my system setup the same way John describes except I don't have the check valve after the solenoid.  There's about 10" of line from my solenoid to my nozzle so I don't think that amount of liquid is gonna harm things.  I also run an accumulator right after the pump which helps keep more fluid pressurized.  My pump is powered by my fuel pump wire so the pump is active whenever my fuel pump is (car running).  My solenoid is activated view my purge valve through the ECU code.

Having the meth system setup this way helps save pump life cause it's not constantly cycling and also as John mentioned it's instant flow.

If anyone cares, I'm running a 100psi Sureflow pump with an M10 nozzle at the elbow triggered to come on at 10psi.  It seems to be working well so far.

Later, Vlad.

[John Hartman]

Vlad, its worth noting that on your system(and my old one) you are using a demand pump.  One that pressures up and shuts off till it needs more.  On many of the newer high pressure pumps, they internally bypass so they always run when they are powered up.  Running it this way would have the pump on the whole time the car is running. 

I'm sure you get this, I just thought I'd add this for new people and for future searches.
