Detonation Knock pre ignition removal reduction

[Davezj]

i have looked at other threads and there is some good info in them regarding what detonation, knock, pre ignition is,

this is a good thread for that
http://www.clubvr4.com/forum/showthr...tonation+sound

But not that much about how to get rid of it. well not much in one place.

so now you have read the above thread and know what it is, how can you get rid of it ?

there are a few ways to do it and i am sure lots of people have there prefured metheds, and i would like you to share the knowledge.

the senario is:-
1. Factory stock car mechanicals, turbo's and fueling wise, all in good condition and running perfectly.
2. Fuel cut limit raised via ecu reflash
3. After market boost control with gauge.
4. 1 piece, 2.5" straight through exhaust very small sports cat, minimal silecer
5. HKS panel filter
6. Boost set to 13psi get regular kocksum counts of 2-3 and below (repeatable results).
7. Boost set to 14psi get regular kocksum counts of 6 and below (repeatable result).
8. Knocksum count tested with a 3 gear 40-80 WOT
9. fuel is shell V-power.

tools available:-
evoscan to monitor knock.
ecuflash to do the reflash if required.
all cable required.
bench test rig to drive injectors (when i get round to building)
ultrasonic cleaning tank for injector cleaning.

i am not asking how to tune out knock with a reflash and adjusting the timing, etc will do this once everything else is set up to allow me to push the boost up. then once the boost is where i want it, i can tune out the very small amount of knock i will inevitably have with the raised boost. i need to be able to get to where i want to be first.
i want to be able to safely turn the boost up to about 18-20psi.

i would assume the following would be sensible.
i need to do/change the following as a starting point,
fuel pump change to 255lph to ensure enough fuel is available to stop lean fueling £40
fuel pressure regulator change for adjustable type to cope with higher fuel pressure from the new pump. £40
bigger intercooler 600x300x76mm to help lower the air charge temp. £80 (Not strictly necessary as we have the stock intercooler but don't know its limitations)
cleaning fuel injector, ultrasonic bath with before and after flow test, etc, (this is free to me as i will have the gear).
wide band sensor £120
boost pressure sensor loggable by evoscan (unused O2 sensor on ECU) £20

now this can be done for about £300
which is nice.

what else would be advisable to do, before turning up the boost any further.
i am not looking at spending more than £200-£400 on top of the £300 spent on the fuel pump, Pressure regulator, and intercooler, wideband,boost sensor, which i know is not a lot of money but thats the budget.

This is all theoretical at the moment and hope fully it will help other in this situaltion in future.

please keep your comments sensible and thanks for your input.
