water meth power gains 2v vortech

I have a 2v with a built short block and stock cams and heads with a v2 s trim head unit. I am thinking about adding the Snow stage 2 boost cooler with VC-50 gauge for boosted octane to make more power with my car. The car does have a tread stone FMIC and a 3.25 blower pulley. I am wondering what kind of gains i will see with this kit. I plan on getting it tuned to maximize the benefits. E85 is out of the question as it is very hard to get where i am located. The car is currently making 425 rwhp and 410 rwtq. I am wondering with this meth kit if i can get close to the 500 rwhp mark or will i have to had a smaller blower pulley or overdrive pulley to get where i want. Also if i can hear from people who have had experience with water meth, or with this kit. thanks

Meth is going to make 91+pump similar to e85. As far as how much power you gain that really depends on how effective the setup is now at keeping the intake temps down. Basically how much more timing can be thrown at it. We also don’t know your supporting mods that’s a limiting factor. If you have a 3.25 pulley put a 10% od crank pulley on it and spin it out too 6500+ that will pretty much max the impeller speed out as long as you have all the supporting mods. The blower will be giving you it’s all plus some.

Besides the intercooler there’s not much else to support cooling . The car has 60lb injectors , walbro 340lph , bbk long tubes and off road x and vortech mondo bypass .

I’d get a 10% OD crank before turning up timing with methanol kit.

I was planning on doing both the water meth and overdrive pulley at the same and getting it tuned all at once if I were going to do it

Maybe I should just scrap the whole plan and swap to On3 for power goals ?

The blower can make 800hp not sure how much you want to make. If you’re already setup with the blower upgrade to a v1ti, JT-Trim or you.

Or ysi not you gotta love iPhones

Do you know how much timing is in it? I'm guessing 16-17*. If you bump it to 21* you might see a 30rwhp gain. Definitely add a smaller pulley or OD pulley with the meth to get to 500.

Wouldn't the JT, Or Ysi be to big for my goals? Wouldn't the T trim upgrade be more beneficial for that power goal? If the S trim can make the 500 rwhp goal with meth and a pulley or OD upgrade without making the blower out Ill just keep that. But if the T Trim or other head unit is more beneficial then I will swap to that.

Its not that it’s better or worse to switch head units it’s about what your goal is. You’re talking about switching to a turbo. Youll make 600+whp with the blower you have depending how you spin it and how it’s supported. Ti trims will make 800+rwhp jt ysi will make 1000+whp with proper supporting mods etc.

You are talking about a turbo swap. Definitely not worth it for 500whp. From the cars I’ve seen and been around blowers are more practical with better street manners/power bands from 1200whp down anything over that it’s becoming a nearly dedicated track car and a turbo setup will be more practical. On our generation cars...

Blower practicality on our cars ends with f1x and ysi’s anything over that our little 4.6s don’t have the power to spin them. Then to beat a f1x or ysi you’ll need a turbo bigger than a 76mm or twins then you’ll have lag lag lag or plumbing weight and plumbing lol. So if you live in Texas get a big turbo but if you live in every other state where a 1/4 mile straight is all you have with no roads ever extending 1.5 + miles straight with no traffic like Texas has keep the blower.

Damn didn’t know an S trim was capable of close to 600 . Sounds like a upgrade for my goals is uneccessary for right now . What pulley combo or overdrive pulley should I be using then for 500 rwhp? I am assuming water meth should give me a decent pump as well , with upping the timing on the car . Also what ratio should I be running with water meth ? Is snow boost juice the most consitant I can get without mixing my own stuff ? Or do I need a higher ratio like 70/30 mix ? Or is this a question I should be asking my tuner

How many pounds of boost are you seeing with your current combination?

11 Or 12 @ redline

Depending on your redline you’re probably only spinning the blower at 43000ish. It’s a 50000+ rpm blower. If it’s a s it’ll make 700ish peak and if it’s a si you’ll see 800ish. 10 percent od crank is 7.25 throw a 3.1 pulley on the blower and run it out too 6000 you’ll be at 50600 rpm on the blower. If you want to over spin it more take the rpm out farther.

I originally thought you had a si. When you get bored upgrade to a si or a bigger blower. You should be deep in the 500’s especially with meth or e85 etc. with that s.

if you buy a od crank or new pulley do yourself a favor and buy the 8rib varieties so if you upgrade to a 8 rib setup you’re not rebuying the same items.

So 10 % OD and drop to a smaller blower pulley, and add some water meth and ill be well over my power goal? not sure if my fuel system will allow anything over 500 rwhp. I have a walbro 340 lph and 60lb injectors

The 60lb injectors can safely make 600+hp peak not whp. You sure you have a 340lph pump? Or is it a gss 340? If that’s the case I’m pretty sure it’s only 255lph.

If you do have a 340lph pump I’m pretty sure they’re capable of 700ish whp with fi.

Far as I know its a 340 lph.
