I am thinking about adding Methanol to my GT2. My engine is built and I run 68mm VTG's. My three tunes allow me to run 93 and MS109. IF I add methanol to the mix I am thinking the tunes should be 93, 93 with Meth, and MS109 with Meth. Any idea what gains (WHP and TQ) I may realize given the tunes with Meth?

EDIT: I am hoping for 900 WHP and (at least) 800 FT# on MS109+Meth.

BTW: I current put down 850 WHP and 765 FT# on MS109. Maximum TQ comes in at ~ 3500 RPM's.

 

using meth for cooling no issues. tune for max power with meth and have any kind of hiccup, clogged jet, bubble in the line failed actuator and you could be buying a new motor.

be careful and use the high end system aqua mist by howerton engineering. stay away from the cheap kits that don't use pulse technology

 

a lot.

 

Are you talking above 50 WHP and 50 FT#? As indicated, we will apply a very conservative tune with (most likely) the Howerton HFS-4 system. Is it possible to mount gauges indicating tank level and failure indication?

 

Will do! My tuner is VERY conservative and would not accept anything less than perfect (and safe). I have looked at Howerton and assume we will go that route. Thanks for the feedback.

 

its funny in the subie world and more than a few pcars meth is a normal way to get better power. in the m/b world its rarely done and considered very risky. boils down to the tuner and he has to know what he is doing

 

Based on various opinions and I am sure, that of my tuner, I did some investigation and found this...................

Failsafe and Flow Monitoring System

The DDS3 flow-monitoring safety system is the finest available in the water injection industry. It is capable of being fully integrated with any manufacturers injection system. The DDS3 uses the same flowsensor and gauge as the HFS-3 and GFS-4 systems. The unit is fully configurable for sensitivity of blockages and leaks. The control box has contacts for switching maps in the ECU(0-5v), actuating wastegate solenoids(NO/NC contacts rated at 1 amp), as well as other features.

This product includes the gauge/display, the flow sensor, level sensor and control box along with associated wiring.

For a little "bling" I like this also.........




It will light up the tank to see fluid level - tis also LED so no heat and will last a good long time.

 

i passed on a brand new howerton kit with dual led tank setup that was installed for a sema show and then removed. gal wanted 500$ and i passed.... still kicking myself for that! my .02 and another 5$ will get you a starbucks coffee but i believe they build the best system on the market

 

Take 30 minutes and read more and VERY CAREFULY... go directly to aquamist.co.uk website, yes it does have built in failsafes, a lot of them, has a gauge with everything you need. if you have an EBC make sure you wire both the ECU and EBC
buy hfs3 or hfs4... no need for v4 but the difference is small and you might want it for a DFI engine or for some more refined settings

yes will make a huge difference, especially considering your 68mm vtg arent performing to well on pump gas... expect 93+meth to be as fast as ms109 before, and ms109+meth to be faster at high speeds where you heatsoak for sure
Dont want to be rude or something, but 850whp with 68mm vtgs, really ?!! i dont think is possible unless a glory run for a short time only... go on some other dynos, like mustangs and see the difference, i bet for high 600s/low 700s if that.. if you look for another 50whp on that dyno, you still might not get there..., but you will have a happier running car especially at high speeds with meth and faster too up there, and for sure 50+ whp on pump+meth vs pump only

dont go meth route if your tuner doesnt properly support it, otherwise is a very nice mod if installed right, set up right, tuned right and of course..... maintained right (includes checking the system from time to time)

Do your homework when installing aquamist and RTFM for 5 times before anything, otherwise pay somebody who knows how to install it and set it up

good luck!

 

Thank you for the warning, I am sure my shop will take every precaution insuring the meth system is installed properly and the engine well protected.

The car is definitely a bonafide 850 WHP built by one of the more reputable shops in the US. The GT2 puts down 851 WHP and 765 FT# on MS109 with the initial torque peak at ~ 3600 RPM's. It IS a very special car with several thousand miles at this power level and no issues to date.

I am investigating the meth option but havent decided I will go there quite yet. I need to do some more research as will the builders making a final decision after consults with and receiving feedback from GIAC. I am very pleased with the performance now but with the opportunity to run 93 and put down 850 WHP it is something I must seriously consider.

 

I have a lot of experience with high HP turbo cars, and there's generally one rule that must be followed:

Don't do meth.

If you only have ****ty 91 octane, then meth can be a nice addition. If you have 93, meth will get you closer to those ms109 numbers. 109+meth won't really give you anything other than helping prolong the time until you heatsoak. But the one time you forget to refill, or the failsafe doesn't work perfectly, boom and you bend a rod and you're out 30k. If you want more power, replace the MS109 tune with Q16. That will give you as much power as the turbos can possibly flow.. and like others said, that kind of power will just be a glory run - it'd NEVER run that much power through VTGs as the heat simply won't be controllable over longer periods. 800whp or so on VTGs with proper cylinder cooling (read: E85 or Race Fuel) is about as far as I'd ever go. Want more, you just need to go alphas or GT turbos.

Edit: and I'm assuming your engine is already built. Todd and I stopped at 700whp on mine due to his experience with stock rods and higher power levels.....

 

Who built and tuned your car?

 

I didnt want to say however I am now pushed in a corner, that would be Champion. I have nothing but good to say............they are a fantastic group of guys, extremely knowledgeable and talented with a very high level of integrity, honesty, and true concern for the customer.

EDIT: Without going into details the build consisted of...............

Mahle Pistons
Carillo Rods
Custom Fuel System
Significant Head Work
High Rate Springs
3.8 Liter

 

Dont know why meth are considered "scary" by so many porsche owners, I used to have 335i and meth is something you almost do after a tune on those cars. Done right its great, especially on a DI engine like the n54.

But yes one must have a well working failsafe....

 

If you look around at most of the high-hp tuner cars (supra, evos, subaru, porsche, etc), you'll see lots of folks don't like meth. Its just adding one extra thing into a system that could fail and ruin your day. And when you can duplicate or improve on it's results with race gas, its just a personal risk/reward comparison to make. Personally, I'd rather pay for race gas or E85 in my case, vs introduce another failure point that could cause significant damage.
