im considering it

 

there should be no considering it. 100% meth on a m7 nozzle progressive setup and a 7400 rpm redline.
numbers will be lolz worthy

 

a m7 nozzle won't do diddly squat on this setup

 

Still don't understand this one myself. If you are indeed running 100% meth I guess I might be able to comprehend why, but I think a 50/50 mix would yield some better results.

 

with the better flowing shorty, i bet you can use less spray and still get your 25*

less back pressure, less prone to knock...all in due time a suppose though. one change at a time then re dyno see how much of a difference they really made.

 

how are you guys runnning your meth nozzles? Im running a 7gph nozzle and could only get about 22 degress WOT and i have full exhaust vibrant header setup catless downpipe and gmp cat back. I find it interesting that some people claim theyre running 25 degrees (im talking peak timing too)

 

Where do you get your meth from? I used to get mine from a speed shop when I was running it and they were closed one day so I got some from a different shop and I couldnt get any timing out of the car, so I went back and asked them about it and they told me its slightly diluted and was only 99 octane Just something to consider

as for the quality of meth convo above, meth has a relatively short shelf life, so if the meth was sitting at the store for a few months before being bought, it wont work as well.

 

...what happens to it? Ethanol is best aged with some liver on the side.

 

its incredibly hydrophilic. 100% gasoline has a shelf life of a few years (2-3) but E10 gasoline is only good for about 90 days. Imagine what E85 or 100% ethanol/methanol do? (its an alcohol thing, so its not specific to meth/eth) Course you can still use it, but its not very good for the car anymore (biggest performance side effect being severely decreased octane as it ages)

 

It would not be worth it with that blower. He is maxing out the efficiency of the MP90 @ 6500rpms with that pulley. If you look at his current dyno sheet you will see that the power is already dropping off.

 

im a tech and work with alot of serious race guys. I get the 5 gallon drums of straight M1 methanol VP brand so it isnt the methanol i run a 50/50 mix with distilled water. funny thing is ive run other balts saying they are running 25 degrees timing and i bust their asses

 

I rapidly sloped timing down after 6400 rpm on purpose.

All those who are spinning the tvs out to 7400 rpm are over spinning using a 2.9 or smaller pulley.
A 3" pulley peaks efficiency on a TVS 1320 by 7400 @ a s/c rpm of 16,033.xx

---------

I refill my 5 gal. meth drum w/ 100% methanol and store it off the ground for a longer shelf life. I've never had a batch of methanol ever go bad on me.

 

Ok so you have the good stuff. Also there is more to the table than peak timing so you may have them in that department

I am a fan of overspinning my blowers Gotta make them work a bit! haha

 

euthanasia contact you bout the 80s yet?

he's goin e-85

 

He hasnt directly, but come to think of it he dropped a hint in my winter project thread on RLF

 

mmm, false

 

could show you my timing in person

those figures are based on peak eff. of 16k; you have a different figure?

 

If he sloped the timing down after 6400rpms that would also be why the power is flattening out. When I set up my timing table after the initial ramp up it's the same across the board all the way to my redline. Add the new 4-1 header that will give better top end and the timing up top, I bet he'll make power up until or near 7k.

 

wont know until I throw it on the rollers

 

Indeed true. This is why I think you'll make power out to 7K with timing up top and the 4-1 header. This is my old 1200ax twinscrew dyno with a quick street tune that cleary needed more work. As you can see even with the stock cams and IIRC 21* timing up top, the car made power to 7K. Yes it made 272whp on a low rating Mustang dyno without methanol injection.

 

nice!

 

Even though people may run their TVS or M62 past its "efficiency" range, those blowers outside of their efficiency ranges, are still more efficient then the MP90 in the heart of its efficiency range. The MP90 on your car is a Gen 4 design which is less efficient and takes more power to spin then the M62 and much less efficient then the TVS.

How much?

Okay. Hold the timing and rev to 7400 then. Deal?
