I think I changed my mind about liking snowperformance Kit because I looked at the alkycontrol kit and it is way nicer. The pac controler that it comes with looks top notch and you can adjust it while in you truck.The alky control kit will run about $100 more but in the long run I believe it will be worth it.

J,

I think I see where you are coming from. PSI is a measurment of restriction in the motor yes but adding more boost is still adding more air into the motor otherwise why go up to 15psi when 5psi is already showing a restriction? That's kinda what you are getting at right? More boost will almost always make more power if the IATs are kept under control and all other factors stay the same as in no major reduction of timing to compensate for the added boost or maxing out the efficiency of the compressor. There is a nice debate going on about more boost vs more timing which is quite interesting.

As for the methanol. The GN guys and Julio included usually state that the meth really helps out with boost and not really timing. Now I am able to run fairly high timing and boost with the meth on but you still end up at a point where more timing with cause KR even if you keep adding meth. I see more of the F-body guys using the Meth to try and add more timing but most seem like they are still learning how to use it so I lean more towards the guys advice who designed the kit and has been using it for a long time. Maybe the GN guys don't vary their timing as much as we do or they are already running high timing?


My thoughts on this matter are

#1 When is it more efficient to loose a bit of timing and use less meth? Reason being is that the methanol is taking up room in the combustion chamber and displacing air which is why meth injection is not recomended for N/A applications.

i'm still learning this stuff too so these are just my opinions and can be totally off base so please don't take it as gospel.

i dont think you can spray too much meth, it has oxygen in it so it really doesn't displace the air. the problem i see is if you spray more than can vaporize then the intake has to carry/distrubute a liquid wich it isn't good at. switching over to 100% meth with direct port injectors would allow insane amounts of boost.

Hmm interesting Jim. I ddin't think of it that way. Still I would think there are diminishing gains somewhere because otherwise EVERYONE and their brother would be running meth and making 1000rwhp right?

I am doing more research and popped across this article which shows a drag car making over 2000HP on an engine dyno and they talk about switching to alcohol instead of gasloine and they advantages I'll quote:

"There are definitely some differences in the tune-up of this motor compared to the old motor. The biggest one revolves around using alcohol for fuel instead of gasoline. Common theory says that it takes about twice as much alcohol as gasoline for the same horsepower; we found that this engine liked even more fuel than that. Another big difference was in ignition timing and compression ratio; we raised the compression ratio by about 2 full points and also used about 4 degrees more ignition timing at the same boost pressure with this engine versus the gasoline engine."
Quoted from this article:

I'll post up more if i actually learn something useful till then I'll shut up. LOL

Ok, found another good thread on TurboBuick.com. This one will directly relate to JSilverado's problem since with the 3.0 pulley he will be near max efficiency on his Radix.

http://www.turbobuick.com/forums/sho...hreadid=142477

Julio quote:

Lots of timing down low will get burst and make the car 330 better. Up top..pull out the timing.

Analogy.. lite the bottle rocket..keep it lit.. Low timing will keep it lit. Look at my recent runs.. all done on low timing at the top. Yet the addition of a few degree's down low yields great results..

Lastly.. this is of course if you have a turbo that can generate the boost. Example is a stock turbo.. at 23-24 PSI in top gear there is no more air to be had..solution is add timing. If you were running a 70 turbo.. you have plenty of steam left.. up the boost.

Add alcohol ..pull fuel.. add more alcohol.. pull more fuel.. keep this up.. watch it wake up when you throw some boost at it.

I have another idea to throw out there for you guys. I didn't see this kit on here, but I just got done reading about it is one of the mustang magazines that I have at my work. It is called a "Mr. Freeze" kit, and they reccomend that you run windshield washer fluid through it. They did before/after dyno's and track times, and the guy gained 91 hp, and went from a 10.18 to a 9.85 in the 1/4 mi. It is a bit different type of setup than some though, because it doesn't have a pump. It has it's own tank, and a valve that opens up when the engine goes into boost. You put it's nozzle in front of the turbo/supercharger, and the kit uses the suction in front of the turbo to pull the water/meth mix that is in the washer fluid into the intake. This also accounts for its low $169 price tag. It is at a ford website http://www.andersonfordmotorsport.com/ go to the media section at the top, and look for the April 2005 article of 5.0 Mustang and super fords "Chillin Like A Villain" It seemed like a pretty cool concept to me, but I don't know how well it would work with the STS kit because of it's rear mount location. You might be able to stick the tank under the bed, or inside the bed for that matter. I don't think that you even have to run a power source to it at all.

ahh, what the heck?

i dont think there are dimishing returns but there may be side effects when you start spraying a ton of meth. like i said distribution is important at some point, a 2nd set of injectors spraying meth would fix this. then what about cylinder wash down? will things be to dry in there even if you are only spraying at wot? some big injectors will be needed like 160's and a real big fuel line and pump. what about oil changes? will you have to change oil every few runs or is it not like that since it is only at WOT.

anyways, i am way ahead of myself here. going to just try the std alky kit and see what happens, that combined with some other stuff like hot parts an maybe some heads and a t88 will probably be more than i know what to do with and if not i dont mind running race fuel at the track.

What would be the ultimate setup would be if these Holley injectors could handle gas, N2O, AND meth...
