So after you install meth injection, do you have to dyno tune the car again, or is a tune not required?
Well . . . . . do you have to dyno tune again?
YUP!
Although you can actually use the Meth on a low setting till it is time to get the tune!
But in all cases such as an Air/Fuel Ratio addition it is your and your motors best interest to do a tune or do it yourself if you've got the tuner like HP Tuners or LS1 Edit!
Do you have your IAT sensor still in the MAF or did you move it? I'd think that if you placed the IAT sensor after the meth nozzle, then your computer would be tricked into thinking that your IAT's are lower. Then I'd think that you'd set your tune up to pull timing in case the meth quit working. Maybe you could tell me if I'm wrong in this line of thought because I'm just trying to learn something here.
I do agree about getting the meth though!
This is the correct way to do it!
I'm scanning my directions of installation, of my just arrived ALKY CONTROL Kit, and it is speaking of putting it before the IAT!
Hence the cold air temps to help the IAT too!
I SWEAR I WILL BE A METHANOL EXPERT WHEN I'M DONE!

Make sure you mount the pump upside down!!! I used some older directions when I installed mine. It needs to be mounted upside down.
You don't have to scan them, here's the directions that I used. These are the ones that Julio uses now too. clemsondave is right though, mount the pump upside down!

When you say upside down do you mean different from the pictures here at the link to Cajundudes instructions?
If so why?
Thanks,Matt
By mounting the pump "upside down" it helps minimize the siphoning effect and thus greatly reduces the chance of puddling inside the air-bridge/throttle body.
In a worst case scenario if excessive puddling occurred you could hydrolock your motor.

Make sure of the pump location. Mine was little too far foward and the udders soaked the pump with water. My pump froze from rust within 6 months. Julio was great. He replaced it under warranty. I don't drive my car in the rain so the water must have come from washing the car.

XLNT suggestion!
I might even make a sheild for it or something to that effect!
Thanks for the link! That is better then the printed directions I got here!
I meant that I was "scanning" with my eyes as I was reading them not scanning on the computer!
At least that is what you all thought right!?
Thanks,Matt
You're Welcome! If you follow the link back to the main directory, CajunDude has one of the Best C5 specific How-to sites that I've found..............and lots of Great pictures too!
I did think that you meant scanning the directions into your computer!
I used Cajundude's instructions. BIG help!!! However, like we have said... mount the motor upside down. I mounted it right side up and puddling in the bearings caused my motor to seize several times. Luckily, I test it before making a run. Julio took care of me and it has been perfect since I mounted it upside down.
For those that already have it, is it worth the 400 to buy, I guess 200-300 for the install, and 400 for the dyno.
$1000 for 100hp?
If my stock LS1 now is making right at 500 then with this mod it will make 600?
You probably will not see 100hp from adding meth/tune. Unless your current tune is REAL conservative. You will need to put on a smaller pulley, add the meth and have it tuned. 600hp is probably right at the very edge of safety/failure. It is also exceeding the limits of the stock fuel system even with a boost a pump. You would either be relying on the meth, or you will have to upgrade the fuel system
You could add the meth, have it tuned and bring it to apx 550rwhp.
And don't forget to move the IAT sensor so that it is after the meth nozzle.

you will not see the 100HP on Meth alone!
The scenario we ran earlier was due to the fact that he was putting on a smaller pulley and would get HP fron that and Meth injection!
I started my Methanol Kit this morning and I'll probably see about 35-40 HP @ the wheels!
Kit is $500.00+ and a re-tune is normaly about $250-$350 depending on your tuner, you can sve the money and install it yourself- it is pretty straight forward to install! Just ask I started mine!

Right, not +100 by istelf but as the original message stated he plans to add 3psi to his TTiX at the same time. That has very good chances to gain 100. My fuel pump is stock, assisted by BAP and Racetronix harness. My setup does not rely on Methanol for proper AFR or increased timing, but I do utilize the benefit of running more boost than I normally can with 92 pump gas. I'm not sure moving the IAT is critical, maybe in hotter climates but I didn't and don't have any issues.

Agreed if you live in a colder climate not a big deal to move it. I'm in Virginia. At 80 degrees outside temp, my timing was being pulled by 9+ degrees. Of course, that can be fixed by tuning OR by moving the IAT after the meth.
my tune is dead on w/o meth...so its kinda cool cause i can dial up the **** and itll fatten it up.......wouldnt want to relie on it. plus going fat on meth aint the same as gas. i dial it only enough to keep iat in control.
so this is a good mod for $1000 total, only gaining 50-75hp. I do plan on having it dyno tuned becuase the tune I got with my SC was just a mail order tune.
