Title: bleed valve on the line to the LDA
Post by: RabbitJockey on April 30, 2006, 06:01:18 pm

i was kind of curious what people thought about this, would it be ideal to put a boost control valve on the LDA.  turn the fuel up well above what you would want it on ur car, and then you can use the bleed valve to adjust fueling under boost externally instead of having to take the LDA apart.  would this work, or would the bleed valve just block the lda from seeing any boost until you get into higher numbers?

with a bleed valve, it will decrease the power under boost connected to the LDA.   Would be ok for fuel economy I suppose.

If your runnig a fairly extreme setup,you could use this to control the power.Would be nice for rainy days,or if you have someone else who dives the car.

not if you turn the lda up before you put the bleed valve on

I thought the FOOT was the best "boost cotrol valve". Set the LDA 'till you "break" (just starting to) smoke, both on "tip-in"  and on full boost. Keep it simple. Too much smoke, you're just wasting fuel and cooking your turbine. No smoke, ok, if your a "greenie" :roll:  or bring in some more fuel.
 Once you get it where it works best, forget about it. Up to it's limits, it'll give you the same results and keep up with any changes to make with air flow.
Like Ron Popeil says "Set it and forget it!"
