What did sean dyno again? 275's give you good enough traction?

Traction is insane. My AGX at full pressure can't keep up. Rear end squats pretty bad on the 100 shot. I've ordered some "helper bags" as they call them. They fit inside of the spring and when you fill them with air they help keep the springs more tense. So we'll see if that will help some more.

No dyno numbers yet. But winter will be the perfect time for them.

Get some coilovers. If you look at one of the pics in my track day thread you see my car on take off. Does squat in the rear.

I wouldn't bee too shocked to see 400+ hp to be honest. I can't remeber the names right now (I think one was BJ something) did dynos with 100 shots and were in the 350/360 range. to shoot a 150 shot + meth I'd wouldn't be surprised so see 410-420 as long as the fuel pump and internals can hold up

im also gonna run meth injection..nothing beats it!
im staying n/a, no nitrous or anything! ill be running a 60/40 or 70/30 mix since im more after the meth vs water lol!
you should try a 60/40 or 70/30 mix and dyno with it...i bet there would be more power had with a higher meth mix!
meth cools the cylinders also, water just does a better job. but you get a higher octane with meth so you might be able to run more timing without knock.?? and nitrous is cooling the intake temps so water wouldnt add much there...i say run a 60/40 and add a little timing and check for knock
thats my plan anyways..

cleaner engine/better gas mileage/more aggressive tune...sh*t whats not to like! lol
sub'd for updates

also. what octane gas you running?
ill be on 91 oct. + 116 octane alchy..should equal out to around 100 oct!
ill let you know in a few im doing the math for it right now

[Kammy]

alright from what im gathering..
companys are claiming that it can boost your octane level by up to 25 points (pre-combustion...before the combustion chambers) on 100% meth.
and it could be anywhere from 20-35 points post-combustion..

reason being is what acts like a octane booster(i guess you could say) in the combustion chamber.
it doesnt add to the fuel octane, it just fights of kock which is basicly the same as adding octane...if you can understand that lol...

heres some Q&A off a meth injection sit...its about water adding octane. it might be easier to understand, instead of what i wrote.

Q: Does it add "octane" to the fuel?
A: No. Octane is a chemical, and there is none in water.

Q: Does it raise the "octane rating" of everything in the combustion chamber?
A: Yes. Octane rating is a measure of resistance to detonation. Since water injection has the effects described above (particularly, the increased resistance to detonation), water injection raises the octane rating.


i say run yourself a 60/40 or 70/30 BECAUSE water also adds conbustion chamber pressure (because its harder to combust)...so does nitrous...so to much pressure and BOOM.
whatever you decide though, will turn out great im sure

I would LOVE to get some if they weren't so damn expensive. I know I'm probably experiencing more front end LIFT and a little rear end squat. Probably why it feels so bad.

Purchased a 190lpH walboro off ebay. So fuel is ready to go. Now the internals I am worried about. Rods are prone to failure around this range. We'll just have to wait and see.

Wow, lots of stuff. I'm running 92 octane. I'm also planning to run a 60/40 mix. I will probably change that once I do some test runs and see what I need more of. Either more octane or more cooling since nitrous has a tendency to accelerate cylinder temps/pressure dramatically.

Kit has been shipped. Will be here Friday. Will probably get off work, install, clean car, then on Saturday will head up to Bill's house for the meet and show off and then since I have Sunday off will finish off whatever loose ends I still have on the install and then begin testing on Tuesday-Wednesday.

good stuff man!
only thing i would worry about is the cylinder pressure!
because waters denser it will increase your cylinder pressure a little...maybe nothing to worry about maybe osmething serious...
only your tune will tell! and go from there like you said.

i cant wait to see the finish!

Cylinder pressure goes down with meth/water injection. Water becomes a vapor inside the cylinder, it never stays in it's solidified form unless you're flooding your engine with a water hose. Lol!

[Kammy]

from what i read...i thought it would raise cylinder pressure..
your highest cylinder pressue is at peak torque! and water being denser i thought it would raise it...but what you said does make sense lol!


"As we approach high tuning levels we will experience considerable increase in cylinder pressure and temperature, but at the same time more power. Since we cannot raise the melting point of the pistons, we must find a way to control and keep the engine components from overheating. Having six times the latent heat of fuel and huge expansion rate from liquid to gas (single molecule of water – not droplets) water is the ideal substance to inject as a coolant. Having absorbed and dealt with the destructive heat, the by-product (superheated steam at x1400 volume increase) becomes an active partner in adding force to the downward pistons. Water is converting the extra heat energy for wheel power. Without water, the excessive heat must be transferred to the cooling system and lost into the atmosphere. Since the quantity of water injected is relative small compared to injecting some six times the amount of fuel to arrive at the same cooling property. To all intent and purposes, we are not advising anyone to go this far but the possibility is there and achievable. In most cases, one can venture into the extreme gently. Since water is free, it costs nothing to continue your quest for a highly efficient engine that produce far more power than the fuel dumping method."

thats from devils own..from that i get that because water raises pressure, in turn "adding force to the downward piston"

thats why i always thought of it like that! but what you said does make since and is actually right!
i just misunderstood...i think

[Leathe of Heaven]

Either way, this shit is awesome!

[ill05ser]

Please take some pix when done. Buying a kit from coolingmist after I install cattman headers and sfr manifold. Subd for update.

[TUKO]

what are you tuning with?

400whp will be cutting it close but just make sure your tune is spot on.

[tonedef]

I have been thinking of building another fuel cell for race gas and have a toggle to switch between tanks.

the cost of the 109 I would run is enough to keep me dreaming in these times, i guess shit seems to be getting better though.

I WILL hit 400 on stock internals, just need to fix clutch and make another trip to Uprev.

[SE-R Altima Driver]

Something seems familiar about this conversation?
Nice to see you have decided to do some research on meth.
Good luck Gene.
Looking forward to your experiments and experience.

[Kammy]

Leathe what kit are you running if you dont mind me asking?
