S&B intake & LBZ inlet elbow on 71mm Cheetah WOW

It wasn't at all optimized before. I need to get a 5 volt boost sensor from autometer that can read up to 100psi and then rescale the sensor voltage table with EFI Live. Right now my boost sensor just gets maxed out and I have to tune it through the max vane table. The timing on my hot tune seems to be about dead on - some of my other tunes in DSP still need timing pulled out - running 45% injectors I am running very low PW and have to pull back timing to make up for how much faster I'm getting the fuel delivered.

I got an LBZ mouthpiece on the way, i have an LLY intake on right now and still have my stock intake. Surely between the 2 i can get it hooked up right? I don't want to have to buy an LBZ intake just for that.

You can use your stock intake. There is NO advantage in using the LBZ intake box, as long as your fan remains off. A good CAI will benefit most people who do a lot of stop-go type racing or staging. You can watch IAT rise while you are just sitting there.

Well I said I could easily hit 12.4s with tuning and Friday night I hit 12.44 with only a couple small tweaks. Next week maybe I'll hit 12.3s. This is still on the worn out BFG ATs and no headers or up-pipes yet. Once again didn't have time to keep tweaking on the tune cause this time I was helping an LB7 customer get in the 12s on stock motor - 12.97 his second pass ever at a track, not too shabby.

How high can the stock boost sensor read? I'm guessing about 50MAP since that's what the boost sensor scaler has in the tune?

It is 3 bar, so around 45.

It is 3 bar, so around 45.

All 3 bar maps I have used could see about 45psia, so about 30psi on a boost guage. Running 0 bar would be an absolute vacume. From what I have used your first bar is used up from atmospheric pressure. Correct

38.5 psi is all mine would read max verified whith my mechanical boost guauge read 42

 

[Turbo Buick 6]

A long time ago I had a Bully Dog outlook and that would only read up to 29psi

 

[othrgrl]

The stock gauge reads to 45 psi absolute so here that is 30 psi of boost while I am seeing 50 on the gauge.
