what timing are you guys using. I was 2 degrees retarded, and my 2 and 3 pistons
cracked the 1st ringlands.Not from detonation.A/F was 11.2.Im running wisecos.thanks

2 degrees retarded of what?

Post up your timing map from whatever standalone you are using. Ignition timing generally decreases with load and increases with piston speed / engine RPM due to the time it takes for the flame front to propagate. The correct timing at each load point and engine speed for your particular engine setup can only be determined by either extensive track and street datalogging with knock detection and EGT probes or with a simple 2-3 hour load-brake dynometer session.

Pistons 1 and 4 are perfect. and piston 3 closed the gap on my spark plug.So larger injectors it is.I see 1000cc are popular for my application.So which one.
RC, Precisions, or a better option?

What kind of injectors are you running now and why do you think that you need to get different ones? What kind of problems are you running into? What is the maximum duty cycle that you hit? What kind of fuel pressure are you running? Why aren't you answering our questions (whose information would help us help you)? What do you mean by "piston 3 closed the gap on my spark plug"?

It was firing on 3 cylinders.When I pulled the plugs to check it was closed not damaged.I dont no the duty cycles.I didnt hook it up to a computer.There stock injectors.I have an inline 255 and a regulator.the psi set from drag.I believe 50 psi.

Wow.

We have an FAQ. Read it. Have you ever heard of a standalone? Read these 2 sentences over ten thousand times. "Take off your Apexi AFC and throw it in the garbage. Take off your rising rate FPR and throw it in the garbage."

Get a standalone and your motor won't blow up. You don't have a timing map.


"The only thing the AFC can fine tune is how much more detonation you want." - SteveShadows

I think i maxed the injectors out.Whats the max boost for stock injectors?

Boost is irrelavant.

Please read the faq.

I'm pretty sure that every question you have EVER asked in Got Boost is answered in the FAQ. I'm not trying to be an asshole, but you need to educate yourself. If you can't educate yourself, then your only other option is to go to a shop and hand them your wallet. Its very very obvious that you haven't done this because you had a built motor and stock injectors and no standalone. You need to either do some serious research YOURSELF and learn a LOT MORE about how EFI works and how to properly turbocharge a car, or you are going to throw thousands of dollars MORE away than you already have.

For example, rough estimates for injector HP levels @ base fuel pressure are given in the FAQ. It's VERY EASY INFORMATION to find.

OK, i just did a quick search for posts by username. I have actually ALREADY TOLD YOU EXACTLY WHAT YOU NEEDED TO GET in THIS POST: http://forums.clubsi.com/ubbthreads.php/ubb/showflat/Main/112353/Number/2157175 and before that in THIS POST: http://forums.clubsi.com/ubbthreads.php/ubb/showflat/Main/105589/Number/1979450

either you are worthless troll, or you are beyond the help of what internet forums can do.

I propose a BAN.

Sounds like you got into boost before you knew anything about it. Research is key to reliable power. BTW leaning out your A/F is what causes detonation.

Too lean of an air/fuel mixture will cause lean misfires at low load and high combustion chambers at medium and high load. It can cause knocking, but detonation (uncontrolled combustion, colliding flame fronts leading to super-high peak cylinder pressures) is usually caused by too much ignition timing advance.

Interesting to learn something new every day. I always thought that detonation was caused by the leaned out mixture detonating early because the mixture couldn't resist combustion because it was to lean. Thus leading to colliding flame fronts. Makes sense though that ignition timing would cause it seeing that the piston would be in the wrong spot during ignition. I'll have to re-read my Honda Books. Sorry if I gave out incorrect information.

Toast, look into buying Corky Bell's Maxium Boost. Great book that explains alot of the theories behind turbocharging.

Purchase it on amazon, eBay or your local book store.

No worries. You are not totally incorrect in any case. No need to apologize. Check out the engine management systems book by Jeff Hartman.
