S/c 5.0 & E85

[rbjet]

Now that it's coming into summer and intake temps are starting to soar I'm sure people with tuned GT/GS's and no aftermarket intercooler will notice a lack of power.

I'm just curious if anyone has had their's tuned on E85 yet and if the cooling properties of the fuel had much of a benefit?

I know a cooler is obviously going to do a much better job at cooling than just the fuel but if say you did a track day in the car would E85 have much of a benefit over 98?

Good question. Coolers for these things are too much coin. Drug money!

What about water/meth injection? Its been proven time and time again as a great power adder (via timing and or boost adjustment) and knock deterant with excellent results

[rbjet]

I guess it's a viable option but is it much mucking around to set up and keep the tank topped up?

Bloosted has a GT and bruce did a 50/50 mix picked up around 20 kw and iam fairly sure did wonders for temps

But in last summers plus 40's as u would imagine it still suffered

Just like any car boosted car meth/ethanol will only do so much

The kits themselves aren't to hard to fit and come with nearly everything to fit except brackets and the bung for the nozzle (my father made it for me though). Topping up is dependant on driving style and condtions but is pretty good.

If it was still suffering then maybe switch back to a 98oct only tune and then use the water/meth with no other changes unless that's what he had done.

There are still compromises everywhere though but for the cost I think it is a viable option and can be kept for any future upgrades or even if there are other fuel or boost issues!

Theres just something I just dont like about water/meth dunno what but just dont sit well with me

[rbjet]

Is the fact that it's not a simple bolt on and leave modification? It just doesn't seem simple to me.

Ran a water/meth set up on my supercharged VR GTS back in the day. Picked up 40rwhp.

that's going back to the mid 90's ,relatively crude system by todays standard but Id say theyve progressed since then. If I owned a S/C 5.0 Id definitely look into it.

Ive been running the Snow Performance stage 2 kit for 18months if your sticking with 98octane fuel I dont think you can beat it. I was making 480rwhp on the stock engine with standard turbo and only a twin 2.5"exhaust, on 17.5psi and 38 degree intake temps. Fitted the water meth kit screwed the boost up to 19psi 2 degrees of timing and it went 511rwhp still on the unopenned engine. It ran like that for over a year with no problems, I tested the intake tems with and without meth in the same day to duplicate ambient temps and on the meth they dropped to 19degrees. I have no doubt then engine would have gone even harder before valve springs or something went, I just didnt have the time to push it harder as I wanted to get my new built bottom end it. Im still fine tuning the car without the water meth before I really see how far the new engine will go on the water meth but I will keep you posted. Im planning on going E85 shortly also and have never heard of anyone runnning it on the falcons with water/meth injection. I dont expect a huge increase in power/torque if any but I think still using a small jet it will help with intake temps/consistancy.

Also as a matter of economy, I get around 450+kms to a tank of fuel and the water meth reserviour lasts longer than a tank of fuel for the way I drive, the controller that comes with the kit I have set it to only start pumping at 10psi boost pressure, then the second dial is what you set for your max boost then the controller regulates the pump output linearly. Also when I pulled the old engine down, it was perfect with 74xxxkms on it. No bent rods, no detonation on evident on the pistons, and no Knock retard occuring in my datalogs and nothing with when listening with the knock box
