Power Loss, Turning up Boost Options

[Island_Racer]

Hello,
I am wondering how i see people talking about turning up boost to 17psi on their CT20's yet no one had specified whether they changed spark plug gap nor retarded timing at all......So i turnt up my boost to 17 psi and was looking to see what happens.....sure enough i lost power on hitting my boost mark and saw leaning out on my gauges. Anyone else had this problem?

So i wanna know what plug gap the stock motor 17 psi users have
also how much to draw on the timing...if that will help

Just as a starting point. o, i doubt it is fuel.....at idle my car shows 30 psi and while driving it has maybe 35-37 psi higher than pressure (aka 5psi boost = 40-42 psi fuel....10 psi boost = 45-47 psi fuel)

Got myself a meth/water injection system to install , now ive read that pre-turbo is good (cooler charged air and increases compressor efficiency), read also pre-throttle body is good as well (cooler charged air and cooler cylinders).....noticed finally, that putting both together using a tee junction is the ultimate .....so question is, how ultimate is it, what works for one doesnt necessarily work for all, so what layout is anyone using with what kind of results??

Currently without the meth/water i have:

CT20B Turbo - 18PSI
FMIC - 20 X 6.5 X 2.5 Core Size
Emanage Blue - Pulled a lot of timing due to heat, etc

and making 260 WHP and 262 WTQ.

I wonder if i get cooling under control how much if can see 10%-15% and safer working conditions....idk

Where have you read pre-turbo is better ?
H20 will eat the turbo compressor blades if injected pre-turbo ?
Possible the H2O will collect/condense in the IC You have a BOV ?
May vent the mixture ?

Better after turbo and IC.
(on superchargers it is beneficially to inject pre-sc to help seal the rotor seals)

You are correct it will help to cool the TB.

Read Max More Boost by Corky Bell.
and more info in Forced Induction Performance Tuning

Both are not a big fan of Water/meth injection, only in cases where
you are octane limited, or limited my competition restrictions. (rally)

WI is a Very controversial subject . YMMV.

Pleasant regards;
