The L67's (with the M90) do not respond well to high concentrations of methanol (even a 50/50 mix is tough to tune for) so there is no real reason to have a seperate reservoir, just use -20 washer fluid.
That is exactly the point. The issue has to do with tuning. After having shops do alky on Mustang Cobra's with Eatons, Vette's with Magnusson blowers, Mustangs with Kenne Bell, Tons of trucks all of which are GM with radix blowers.. and they all respond favorably to 100% methanol.
The L67 platform needs someone smart doing the tuning to hack the computer to allow fuel to be displaced so power can be made. I dont own one of these cars.. but I can tell you highly doubtful it is what it is.. So it gets back to tuning abilities afforded.
Perfect example is the EVO8.. why do you think they ditch the stock ecu in favor of an AEM. Its for that reason.
I have had customers have their systems tuned by professionals where power was lost.. same car taken to another tuner picks up. Difference is one picks up the phone and calls.
One part of an alky kit is getting reliable components under the hood/in-car. The next hurdle is tuning. Without both of those.. the performance will never be correct. Period. This is why I dont make kits for the SRT4 Neon.. or a 1998 Jag with a blower.. or other platforms cuase they cannot be tuned appropriately. Sorry for the ramble.. if you want to start a new thread "ideas/thoughts on tuning an L67".. no problem. We can address that.
With that said.. buy your parts and systems from those that can support your particular platform.. cuase spraying a motor without in depth knowledge of what and why is a sure way to create more harm than good.
That is if your looking for a positive result.
fett87, when you get older you'll find that you get set in your ways of doing certain things becuase it gives you a positive result. The old if it aint broke dont fix it mentallity starts to set in. And new ideas are met with resistance. The idea of running the times with a car as heavy as mine on 93 octane just a few years ago was unheard of. And I too met and still meet tons of resistance from those that stay with the C16 race gas. Still saying that alcohol injection doesnt work. I have a recipe that if followed works like a charm on a TR. Not saying it cannot be done another way... becuase Buicks have been getting sprayed since day 1. At BG this year 2SLOW (Dennis Hogan) showed me the tail lights on his car. He ran like a 10.6-10.7 using a small pressurized tank, couple NOS nozzles, couple of trico WW pumps, set of hobbs switches, etc.. while barbaric... it got the job done for his means that day. There is more to the car... just is what worked for him.
