Yea the forum is back up!
I believe the owner of the car is using 100% water, in that case I believe the injection point should be further down the pipe to allow for more evaporation, better cyclinder distribution, less left overs and even more cooler temps. Or go direct port and screw evaporation and just focus on incylinder cooling.
As for direct port injection, It requires a special jets with filters and is not easy to set up. To run any kind of methonal, will cause long term damage as the methonal will pool up on top of the valves waiting to go in the cyclinder. To see the best gains out of the set up, you would have to run 100% water and run your car on the edge. Cool if you have a race team to monitor it...
I bought a cheap UPIC from ebay so I could try many jet points, with data log lab I have notice 10- 20 HP difference in jetting locations. Closer than 6 in to the tb I would loose power, even when tuned for the difference. 12-18 in away seem to provide stable and dependable results, consistant run to run. To far (ic exit) seem to provide cooler air temps, but no timing advantage was allowed.
So when your setting up your system jet placment IS crucial along with which mixture your running, and what boost. You change any of those things and you can make a big difference.
Good Luck
