Predator installed

[Felix C.]

How much timing advance does the Predator add and where?

Can you monitor KR with the Predator?

Does it change RPM redline? Cooling fan turn on temp?

What does it change specifically?

i don't have one but i've looked at the predator performance tune and it added a few degrees. at 4800 RPM (~peak torque and it's a "low point") it's 20*. mine's tuned with HP Tuners and it's about 2* higher across the board

Speaking of crazy talk, instead of water how about another combustable liquid like rubbing alcohol or methanol. Put a little alcohol or methanol on your finger and blow and you'll feel the cooling effects of evaporation much more readily than water, and on top of that wouldn't it also be combustable? (Not sure what it would do to the A/F mixture, I'm no combustion expert)



Wow, really? That is a long time. I'll watch my IAT on startup and it lags but it seems to be only 5 to 10 seconds behind. And on the highway it seems to take maybe 20 to 30 seconds. I'll time it next time I'm out. If your IAT's are only 2-4 above ambient it could be I'm getting about a 5 degree heat soak. I've got to get back out and do some data collection.

Youd never want to inject alcohol into your CAI youd cause a fire . Alcohol is excellent fuel by itself but as far as injecting any combustables before the intake manifold it should never be attempted. water injection does work they used to do it to high performance aircraft engines (both piston and jet). It wouldnt work well as was previously stated however all engines are designed with water ingestion as a normal factor so a car could in effect run fine with a wetted intake filter. will it help performance ? doubtful.

My original thought was not to use water as a means to gain performance so much as it was to maintain that which we already have. That is, the water evaporation would be used to keep the IATs low enough to prevent the computer from pulling timing. As we all know, these cars a good performers, but heat soak is a major issue. If we could sufficiently reduce IATs, we could mitigate the issues associated heat soak, and subsequently eliminate the concern that we are going to have to deal with less than optimal performance on a hot summer day after having been tied up in traffic. During this thought exercise I have concluded that this is not the solution to the problem. Besides if we really want to cool the incoming air, we might as well do it right and use some funny gas.

1. I haven't played with it yet, I'll let you know.

2. Yes

3. Yes and yes

Thanks. Appreciate it greatly. I understand the benefit of a Predator and similar tuning is the ability to quickly reset programming to stock levels when needed to retain warranty.
