Timing???

[boost_92]

For those of you who have a boosted f22 what do you have your timing set at? and how many degrees should i set my boost retard at to be safe?

[blazen_accord]

rule is 2 degree for every psi of boost, but if you manually retard the timimg, then your low end will run like crap since your about 10 degree retard. This is Ignition timing if your talking about camshalf timing then leave it stock, unless you have a regrind turbo cam and an Adjustable cam gear.

get yourself an boost relate retard unit from MSD it call an BTU, it will retard related to boost and return to stock timing when you not in boost. I did not have an BTU and retard my timing only by 7 degree and blew my engine at 12psi.

Actually from what I've seen you'll want to start out with retarding timing 1 degree per pound of boost.

i totally agree, 1 degree per psi. and dont be stupid and run more than 10psi. i will gaurentee u, u will blow your piston ringlands.

so whose right.. ?
1degree per PSI
or 2degree per PSI
???
also

sorry man but u're wrong. if u want proof go search honda-tech, where their are more boosted cars than their are here or any other accord site.

2 degree is to be safe, but most go with 1 degree per psi. so unless your boosting over 8psi, 1 degree retard per psi is just fine. Manually changing the timing is turning the distrubutor(sp?) on the engine. but once you set it manually then even if your not in boost the timing is retarded meaning, slower off the line and also slower when you floor the gas.

AN electronic boost retard device will make retard only when it sense boost, so you don't lose power.. MSD BTU is one of them
