Water/Methanol Injection...

If you want to run the car hard when the ambient temperature is over 90 degrees detonation can be a factor and methanol will help.

That is an over simplification aimed at minimizing the attributes of methanol injection. That is to say it is locking the system into a one dimensional box.

If you add other variables, and this is just to add one, an actual true standalone ems, capable of more precise handling of the engine management, you will see good strides imho.

There are many more advantages to running meth that just preventing detonation. I run one on my direct injection audi rs4 to prevent carbon buildup on the valves. Carbon buildup is a well known horsepower robber in FSI engines, and can rob engines with as little as 20k miles of 50 hp or better.

I again reiterate my earlier statement for one to do their own research, and even try running one to give real world data. I am putting one on my lt-5 project, along with a ems, and between Pete and I, I can guarantee you will be updated on the results, as we have a sort of wager on the outcome of running a more modern ems on the engine.

BTW, for what it is worth, my audi rs4 is a n/a engine, and with installation of the snow methanol injection kit I picked up 18 awhp. With the additional loss through a awd platform compared with a rwd, if it was consistent (not claimed by me) between the two platforms you do the math. You should also be able to see the benefits of limiting carbon buildup.

Stop working so much and get this experiment done Rob, want to see how this turns out

From the tuning work we did on my 12-1 368 I know it did not want to take much more than stock timing without triggering retard on pump gas.

Well this is how we are going to approach it this time Bob;

I am meeting Pete on Wednesday, and he is going to help me get my engine in condition for dropping into my 71 GTO.

I am going to install this with a haltech 2000 platinum ems. I am also going to install a snow injection kit.

I will baseline it without meth, with meth, then do the port work and tune without meth, then with, and so on.

The GTO will be a great testbed for everything I want to try with this powerplant with much less difficulty.

Oh, and jerry is once again front and center helping me as well

I also think that once Pete plays with the haltech he will move to the darkside

Okay now you really have my attention, this should be most interesting

I think Cuisinartvette had this on his LT5 when he had it

I'd like it to work out! Can always use more hp.

Ok, once again I am going to put my testicles on the chopping block.

I am not calling anyone a liar, or saying they do not know what they are talking about. The vast majority of you members have a ton more experience with this powerplant, and that counts for a lot.

The above being said, a lot of individuals are stuck in a time work. They tune on 20 year old technology, and the limits that it brings. If I am wrong I get to eat crow served by Pete, but I really do not think so. Although I do not have a ton of experience with the lt5 it is still a dohc air pump.

Pete thinks he will need a week or so with my engine. I want this done well before BG so I have a car that is worthy to drive to your meet, since my son will be taking HIS ZR-1.

Pete as in ZR-1 Pete in the forum??

Yup, as in chi-town, greek guy, ky Pete

Okay, just trying to keep it straight (in my head)

Yeah I know Pete, known him for close to 12-13 years now, might even be 14..

Lost count.. Is he working his magic on your LT5 for you?
