TDI Coast2Coast: I know this isn't the place for it, but what exactly does your methanol injection do? Is it almost acting as NOS would for a gasser? or is like a gradual injection that produces more boost pressure? Also, how would it affect engine longevity?
EDI: hmm just did a search and turned up a ton of info. surprised i haven't really seen this before.
I think it actually may be related to this thread in a way...Waiting for someone to interject some more knowledge on the subject(meth+flaps).
I'm still in process of learning myself, so some info may not be exactly correct or possibly totally wrong, but from what I have read/observed:
In short, it injects according to boost or EGT. I use in on Boost mostly, but EGT when towing, though both ways keep EGT's lower.
Using 50/50 mix-
It adds(now) much more power(the ability to burn fuel more efficiently and more of it). The traction control will activate in 3rd from a rolling start at 1,700rpm on a dry road(after unplugging IFV). Doesn't do that without the methanol. I'm pretty sure I can kick in TC from a rolling start in 6th now on a hill with meth on during wet conditions somewhat easily. If not 6th, no question 5th.
Helps steam clean the motor...depends on what mix you use as well. More water, more cleaning effect. You have to be careful going either way(more water/meth).
Too much injection of any mix can cause quenching and possibly major damage. Or having tank above nozzles and having it gravity feed
(mine is a below nozzles). You have to test carefully and not move settings too much at one time.
If you don't lug the motor and overdue it, IMO, it helps to keep things clean, lower EGT's, add power, reduce smoke. Lower EGT's can never be a bad thing IMO.
As far as longevity...I think it is all a matter of how much you use. I don't see using it carefully having any adverse effects, though that I can't say for sure. I haven't noticed any(unless it caused flapper valve to fail...which I don't think so since problem with my meth existed upon install, but was unaware).
Being that I cannot quench it with the main nozzle, I am going to go up to a #2 and see what happens. It that doesn't quench...
Going to need more suspension upgrades and something to help with torque steer(which is already tough to control when floored as well as keeping traction control from kicking in
You could also find a WWII pilot and ask him how much power it will add, especially at altitude...My uncle is an ex military pilot, not WWII, but when I told him I had put it in my car, he talked about WWII and how important it was...Very interesting actually.
