my friends also brought to my attention that it may have been a spun bearing(s), too much boost, the alky (like you folks have stated above)

so.......
curious.....what is the nozzle size on your injection kit?

there is absolutely nothing wrong with meth. do good research, get a well put together kit with a good failsafe. rely on the failsafe as a safety net and not rely it to save your motor from using a high failure rate kit.

TTP-Engineering runs ALL their meth tuned Evo's over 30psi and there is no long term reliability issues as a result of this practice with proper tuning and TTP meth injection kit (or another kit of sufficient components).



TTP-Engineering does not seem to experience any of the "bad gas" situation that seem to happen so frequently elsewhere. The fuel must be specially made for our market or something. Crazy...


I would like to take this oppportunity to mirror Al's warning of danger. If your injection system and reflash tuning is not optimized for the conditions in which is safe for 30-34psi on factory turbocharger boost, then your engine health may be in grave danger.

Luckily there are meth injection systems and tuners with experience enough to run safely at these power, torque and boost levels on pump + meth injection. Its your job to choose the most competant system and tuner to insure the longevity of your motor.
TTP if you are trying to say that you have some special skill or talent to make running 30 plus psi with meth injection on pump gas safe for a STOCK BOTTOM END - then I would have to strongly disagree with you.

In the end it is for the customers to decide how much risk they want to tolerate, and which tuners and advice they wish to follow.

To clarify, my advice and suggestion is to run a moderate level of boost with alchy injection and pump gas - particularly on a kit like the SMC which has a smallish pump that only has limited flow rate.

I sell Aquamist systems which flow several times as much alchy as the SMC kit in a much more precise manner and with built in safe guards. However, even with a more adavanced system like aqua mist I still recomend moderate boost levels on pump gas with alchy.

Also, all such systems must be set up on an individualized basis with careful attention to any knock and careful data logging.

I stand by my suggestion that customers with stock bottom ends lean towards a slightly less agreesive boost level - especially on the stock turbo which really is well beyond its efficiency map at 34 psi which could only be a breif spike and a lot of intake charge temps.

At the end of the day, I do my boost levels a bit more conservative but feel more confident in the long term reliability forb the customer's engine.

detonation, too much boost. If you stay with same turbo setup, I would re-build 2.0

Al it really sounds like you are trying to blame AMS. Not only is that unprofessional but it is unfair as the engine has not been torn down. I have never seen AMS start commenting on one of your numerous threads about bad customer service, shotty tunes, or overall bad experiences with you. Just look at this thread and maybe you will begin to realize what most people who have been around really think of your tuning.

To the OP: pull the head and begin to look for the cause of failure. It sounds like your kit stopped spraying. Good luck and get it running stronger then before.

If someone plans on running 26psi. Please don't waste your money on meth injection. Spike your tank with a gal or two of 110 and have the same results without the risk.

I am curious if Al could tell me what the efficiency of the stock turbo and AIT temps are at 34psi on a 1000cc injector spraying 100% VP M3 methanol at 150psi?

If not, please move on to a subject you are well versed in.

u know what the engine blew 2 days after ams tuned it so why not look that way, its either a poor tune or the kit failed in 2 days , i go with the poor tune. not to knock ams, 394 whp on a 20g , on 91 octane(if this is correct) sounds like pushing it to beyond max, dont take it as ams messed up, this guy from ams went out to hawaii and could have done better.

I posted up my research on another topic but im sure the tune by AMS was fine, Im sure nothing wrong with the kit either. the reason why this happens is because methanol exhibits hydrophobic properties in that oxygen will bond with the water/fuel but the other parts of the meth will not. So he sent extemely lean from having all this oxygen and not fuel from the hydorphobic problem of the meth.
were you using a fresh tank of meth, no more than 1 day old. or were you using the same tank that was used at AMS?

Main Entry: hy·dro·pho·bic
Pronunciation: -'fO-bik
Function: adjective
1 : of, relating to, or suffering from hydrophobia
2 : lacking affinity for water

Main Entry: hy·dro·pho·bia
Pronunciation: "hI-dr&-'fO-bE-&
Function: noun
Etymology: Late Latin, from Greek, from hydr- + -phobia -phobia
1 : RABIES
2 : a morbid dread of water

"hygroscopic" might be the word your looking for.

If water takes the O2 out of the meth wouldn't that make the afr richer?

But please give us a link to your "research"

Actually I know that AMS did a great job on the tune and I dont blame them what so ever - they certainly know what they are doing

IF YOU ARE DRAWING THE IMPRESSION from my comments that I am blaiming AMS you are DEAD WRONG - on the contrary I am sure that AMS did everything they could to give the customer a safe and well sorted tune

MY POINT is that stock motors are not bullet proof on crap gas at 30 psi of boost - I am not pointing fingers

I deal with customers on a daily basis who want to run 30 plus psi of boost with alchy and I always have to try and take the time to share my thought process on this

I am trying to use this situation as a example of why it is that I suggest to customers to run a lower boost pressure. Running less boost gives you a greater margin of saftey and makes it a lot less likely for things like this to happen.
