Re: How much will it take
nice write up joe.
oh and darton MID sleeves are pretty nice. i've delt with darton for like 900.00 you send your block off and they will resleeve it for you. i got mine back in 3 weeks and never had any problems with it. it was worth it to me. i'm sending my new block to them to. but they are giving me a deal this time

Trust me, no ***** involved. Pure intellect.
Sir Harry Ricardo discovered, oh, about WW1 era, that after a certain volume of water was injected into an engine that the engine's cooling jacket was no longer used to shed heat. He took a brand new $$$$$ radial aircraft engine, dropped all the coolant out of it, and cooled it solely by water injection. Ran it in the lab for something like 200 hours of wide open operation. Upon teardown and inspection the engine turned out to have suffered completely normal wear and tear for the amount of time it had operated - still brand shiny new. OH NOES!!!!
Now, the only reason why everybody doesn't run water injection is because it's another container you have to fill. Oh, god. Pouring free water into a reservior everytime I fill up with $3/gallon 87 octane, in order to have a knock limit and engine thermal safety orders of magnitude greater than a mere $500 intercooler it took a sawzall to clear enough space to fit, is such and inconvenience. I am such a Christian martyr.
Guys, don't try to pour water at home. Leave this to experts.
I'm talking about keeping my coolant jacket AND running water injection. ***** of steel? Try total safety.
Intercooling is like an MSD - it gets the riceboys hard, accomplishes very little worth the price and effort. You meet LOTS of really nice, excited young men, with a really big intercooler. That's what it's all about, right? Just like OMG V-TECH Y0! you have to have it to get the respect of strange men you haven't fucked yet.
heheh...

Been calling BOVs, especially RFLs, Riceboy Mating Calls for some time now. Now ICs are going to be "Homo Magnets." Anytime the Riceboy hears the mating call, or sees the IC, they absolutlely positively HAVE TO BE YOUR SPESHUL NEW MALE FRIEND WITH POSSIBLE LONG TERM RELATIONSHIP.
Yup, no IC, and I think I'm routing my BOVs back into the intake ducting. I don't want speshul male friends - I just want it to really really hurt when I break it off in a built domestic or a Honduh-Tech Super Stunna. The dents + dirt + rust give the car it's trailertrash mystique... why ruin it with the over the top stuff, eh?

Mr.Davis. I'm curious about your planned manifold and wastegate setup/design? I also don't understand raising the static compression ratio when the current school of thought swings in the other direction, espicially with the use of pump gas.

Re: How much will it take
With a pump gas knock limit of ~350 whp on a 10:1 CR D-series, in traditional air-air IC fashion... pushing 300 on a 12.2:1 CR with liberal water injection isn't going to be that large of a stretch. To make really big power, at some point you HAVE to have a bigger combustion chamber, period, but I'm not there yet.
The water will keep things cooler than an air-air IC setup, so my pistons will remain strong instead of becoming soft as aluminum is wont at higher combustion chamber temps. The water will also raise knock limit considerably, preventing the pressure waves/spikes that cause softened, overheated aluminum ring lands to break.
I'm running GX pistons on the SOHC, because they fit on the ends of the LS rods with minimal ------- around. It's cheap. It's expedient. If I was made of the dollars, it would be ~9:1 CR, have a bigger turbo, and I'd be pushing for a bigger goal. As it is, I just want to overspin a .60/.63 and watch it die after 7000 miles.
