W/M + gt2871r elim safe?
I currently have a gt2871r elim on my car boosting ~21psi. Its starting to get hot here in vegas and i wanted to add W/M injection to cool IAT and also raise the boost a couple more PSI, maybe even add timing if safe. I was wondering if this was safe on stock internals? or should i just save up and do rods first. Id rather do W/M first since it would be cheaper but i dont want to blow my motor. Also, roughly what kind of AWHP could i be making with my set up + W/M. other mods are in my sig. TIA

Now we're talkin serious power. You have pretty much 2 options. The .63/.64 A/R or the .82/.86 A/R. The .63 and .82 are T3 flanged, and the .64 and .86 are T25 flange. T3 flows better. With the .82 you will have more lag, but more topend power. You also will not have to swap out rods. With the .63 you will have much faster spool (20+psi before 4k), but you will have to swap out rods. You will need Tuning, Exhaust Manifold, Custom Intake, VR6/Ford Lightning MAF, 440cc/630cc Injectors, AFPR, MBC/EBC, Exhaust, FMIC, Clutch, New Mounts, and Walbro 255. (new fuel filter at the same time is a good idea).

But he has the 2871r Elim... Let me start by saying I am no where near an expert on turbos, so this is just my opinion:
I'm sure adding the W/M would be perfectly safe, but if you were to add more boost, and possibly timing, you may start to think about the internals. Mike-2pntZero and FasterThanUrsA4 would be able to give you a more informed answer.

Water/meth is a great option to make "race-gas like power" on pump gas. Its very beneficial in many senses, and has a few different uses. It depends on the mix of methanol and water you decide to run.
Some people choose to run a very mild mix(certain types of cold weather washer fluid) which is usually a 50/50 or less type mix. This can add decent power and cylinder cooling/cleaning, the power part really only comes in with adding more advanced timing (which means your tune will need to be changed).
Other people decide to use a very high ratio of methanol to water, or just straight meth, and they tune accordingly. Its basically like a different race gas at that point, lots of timing, lots of boost, lots of power.
Deciding whether or not you can run stock rods with w/m, depends on what kind of a setup you go with. Mike can chime in with the torque onset info of the 2871r elim because he sells them and is used to them, but I dont have any real experience with them. I know of A4's that run up to about 350awhp on stock rods, and I used to run my T3/T04 on my stock bottom end with no problems making around 320awhp. But it really depends on the torque numbers and how hard/fast it comes on.

[QUOTE=chris120391;1301111]not trying to be rude or anything but your copy and paste reply said nothing about W/M injection, it also said nothing about my elim set up. W/M injection is supposed to make it safer by reducing knock/detonation via cooler IAT's and higher octane rating, but due to the added power i was unsure if it was still safe.

I've seen W/M on a 98 aeb a4 with a stage 3 and it ran fine with now problems as far as internals. just keep up with the oild changes and make sure coolant levels are always on the up. I would not mess with the timing.
you could maybe paly around with the spring rate in your DV. Do you have a FMIC? you could benefit from that if you dont with that setup.
