Default Meth injection or IC spray bar

Well, I bought the SMC water/meth injection set up and I am now unsure if I want to keep it. Here are my thoughts:

I will have to relocate the battery and all that stuff so I can fit it under the hood. Also, no one in my area has much experience with meth so I am a little bit leary about getting the proper install and tune.

The intercooler spray bar will aparently add approx. 30rwhp and drastically cool down the intake charge. I have a guy who will install it for free, and we will mount the bottle behind the rear seats (and paint it) so it will look incredible.

What should I do, go with the alchy, or go with the IC spray kit (the NX one)

Any advice is appreciated

IMHO the water/meth kit would be more flexible if you have bad fuel or low octane issues. No location info so I can't guess whether you are forced to use ethanol, oxygenated, 91, etc.
Those IC - N2O coolers look waaay cool and have an awesome effect for short bursts. Only worry I would have would be running out of nitrous at a bad moment and spiking the IAT's. The water/meth could also run low but it's easier to see a change and fill it up. Bummer about the work required to install the alky kit tho...

i'm going to be running an n2o i/c sprayer, the difference is i'll be spraying inside the intercooler 30 shot should work very nice.

I hope you're not spraying INTO the intercooler. Sheetmetal bombs aren't cool. If you're going to spray, shoot it in the charge pipe and either purge into the motor or onto the intercooler.

FWIW, I'd run an intercooler and methanol.

As said.. I would just add a small shot of nitrous. Although the meth injection will be cheaper.

I would love to run a 30-50 shot, I just don't think my engine would hold up...I considered both IC sprayer and meth, but I don't have the funds right now so its one or the other.

and how would it explode? N2O nozzle on outlet of i/c before maf.

Methanol and nitrous serve 2 TOTALLY different purposes.

Nitrous is the equivalent of adding more boost. It makes more power, but you need to compensate with more octane, or less timing.

Methanol is the equivalent of adding race gas. It lets you turn up the boost and timing to make more power. You will make a lot more HP on pump gas + meth vs. pump gas + nitrous. The intercooler spray bars are worthless, I had the NX one on my car and it was a steaming pile of crap. Meth takes IAT's down 30, 40, 50 degrees. At 16 PSI on my old 76-GTS I could see sub ambient air temps. With the Ntercooler I saw like 10 degrees lower if I hosed the IC down.

I am sure the statement you can make more hp with meth than nitrous is referring to spraying the nitrous across the intercooler. See how if you spray nitrous with the boost into your engine, you will see huge drops in air temps and increase in boost pressure a bit.

And the intercooler spray bar only works if you air flow forceing through the intercooler core. Jerimie over at Procharge saw some descent temp drop, I do not remember how much but it allowed him to run less boost and run quicker.
just my 2 cents.

I'm not a fan of those sprayer bars because I think that won't do that much overall and might be useless when making a pass. If you spray during a pass won't the gas disperse too quickly?

Kurt @ W2W is using meth on his Silverado SS turbo truck. So to me, if Kurt uses it then it must have some good applications. I kind of got the sense that anything over 10psi necessitated meth or race gas (assuming you run enough timing to try to make any real power).

Thanks John....I think I would prefer the alchy, but no one here really knows much about it

Try looking over on www.turbobuick.com

They have a whole section on alchy stuff. Might help you decide what is best for you.

Personaly, I think you would be better with a methanl injection setup as aposted to the NX spray bar.

Nitrous on the intercooler or in the motor, you'll make more safe horsepower with methanol on pump gas. When I spray meth at night you can see a film of condensation build up along the charge pipe past the nozzle. Nitrous never did that for me.

or maybe stab a sharknozzle with nitrous and meth in place of the fuel.

Agreed. Check out the Buick boards and turbomustangs. Both groups have been doing alky/methanol injection a lot longer than the F-Body guys have.

Well, I have decided to keep the SMC kit (I think) and perhaps I will pick up and IC sprayer down the road. I think the car will like having and intercooler, IC sprayer, and meth inj. to cool down the intake charge
