the only difference with 07 is that powertrain did the ecu calibrations not performance division. say it again armcclure: ALL lsj are the same.

no no no, im sure mine has to be different though!


one shiny rotor?

ALL LSJ's ARE THE SAME!!!
I only said maybe l61 because I knew there were a few differences... Frankly I haven't paid much attention to anything but the lsj motor and le5/lnf blocks.


If that's the case you would have much bigger problems to worry about lol

The idle dreamy though.. Yeah, fuel system is completely stock otherwise.


Yes, they are in the low 70% duty cycle on 93. Upper 90's on the blend

Is there any benefit to meth with E?

I wanna run E so bad



I know. Cool story.

They don't have E in Ohio??

They do, not near me though :/

I love running on the E.

Mainly cooling purposes. In that case you can just run straight distilled water. Some people use meth with E85 as a bandaid to give them more fuel up top if they dont have the fuel system to support it.

I tried straight h2o and it bogged just a hair at low rpm when it kicked in, like at 3k. Running a 20% mix (washer fluid) cured that.
I run it for blower cooling and the boost gain. Too many ppl discount the effect of the w/m tightening up the rotor-case tolerance. I gained 1-1.5 psi midrange spraying 7gph.

U was running straight h2o aka water in ur engine? Aint that a bad idea or did u mean pure meth?

ThexGovenor

I think the water attomizes and uses the heat from the blower to do this. Correct me if Im wrong...

InfraRedline

Good info Alan. I considered running 3gph or something small of distilled water, but I don't think it would do much for IAT's since before E85 my old 50/50 mix through a 5gph barely made any difference in intake temps.

Yes I would discount that statement. I would suspect that the meth mix is doing sfa to the "rotor-case tolerance" I would suggest you are making more power and the back pressure is increasing with the stock exhaust port as you make that power, and the pressure increases.

Think about it.

Actually John water/meth does tighten up up the rotor tolerences because it doesn't compress and creates more boost.

Ok what about putting in forged pistons, do I need to re-sleeve the cylinders?

Bluelightning

iTrader: (8)

No. But you will need to measure the sleeves to make sure they are straight. If not, you will need to bore them.

show me the data. looks good on paper. I am not seeing it. maybe I ask eaton. and ps, the water meth erodes the coating on the rotors. that much i have seen over and over.

Bluelightning

iTrader: (8)

I'm sure 100%METH or Euthanasia will chime in with the data you are wanting.

As for the coating coming off due to meth, here's some informative info
