opti spark failing at 6500rpms - NJFBOA - Home of New Jersey's Camaros and Firebirds

10-25-2009, 07:47 PM

so as most of you know on my 6th run at the track rental i had some issues and had to be pushed onto a trailer and towed home (thanks to everyone that helped). well my opti spark failed at 6500 rpms going through the traps and this is the after math. MSD cap and rotor are on the way so i should be back at the track within a week

Awesome!

Something to look forward too!

are you sure that was the fail of the opti and not bad engine part causing it to shatter like that.

Yea like that bad engine that kept blowing trannys... oh wait...

10-25-2009, 08:42 PM

are you familiar with the LT1? theres really not anything on the engine that could cause it to fail like that

Interested to see how the MSD holds up with your car.

DAMN....... i got ripped on while i was away.
YeS , i am a ls1 nuthugger & proud of it. and.............
...........
umm........ for your information there is parts on the engine that could make the opti go bad.

1. bad water pump (not this yours cause it cracked, didn't take a s*** from coolant entering it.)

2. bad seal getting oil into opti ( not your case either)

3. beat cam bearings,beat cam, excessive play causing a high vibration in the opti causing it to shatter. (high rpm you may not feel vibration in the car.) oh wait...... its an lt1.... everything vibrates, rattles, clunks, & knocks !!!

4. could be just old opti and due to heat it came apart.

i dont know the history or the car and what is done to it. if its a stock or old opti very well could do what it did.

hey, and i rather rip my trans out 10 times than replace a outdated, ineffecient , FTL optispark anyday.

Electric water pump. NEVER heard of oil getting into the opti from the back. you have the same chassis in an LS1 car so everything vibrates, rattles, clunks, and knocks in your car too. the opti had less then 100 miles on it. well see what happens with the new cap and rotor.

BTW didnt you just blow up an LS1?

its actually a VERY accurate ignition just in a poor location

Oh yea? What happens when you go past 7k...?

S.J.SLEEPER · 10-26-2009, 12:31 AM

well we seen what happens when you go 6500 rpms. maybe the rest of the engine will come apart like the opti @ 7k

and btw (I) didn't blow up my ls1(& its not a ls1)
fpr busted diaphram causing cyinder full of fuel ='s broken rod.

I just blow up transmissions & rears due to the h.p. the almighty
(ls1) puts out.

don't get your painties in a bunch ltnone boy

10-26-2009, 12:32 AM

the PCM ****s out, not the opti. theres people that spin it to 10k with aftermarket computers

Your car run yet?

S.J.SLEEPER · 10-26-2009, 12:34 AM

on a serious note.... what brand cap & rotor was on it?
if your pulling car thast kind of r's you should be using a piece of s*** aftermarket replacement part. oem gm part or msd/accel.
not a autobone or notsoadvanced auto chinese part

LTb1ow · 10-26-2009, 12:35 AM

It was a GM unit.

yes it was a full GM unit, because it was just the rotor that went im going to throw a MSD cap and rotor on it (the metal piece is bolted to the rotor rather then using plastic rivets) and see how that works, if it happens again then i know i have a problem and ill go from there. i dont buy cheap parts

i spend too much on my car to cheap out somewhere

Edit: i know i should probably replace the whole unit but i can have it out in 10 mins (literally) so it going in and out is no big deal to me.

S.J.SLEEPER · 10-26-2009, 01:22 AM

you should check for excessive play on the camshaft before reinstallin it.

BigAls87Z28 · 10-26-2009, 01:56 AM

WHOA!! Our Ignition parts are Wells units.

sweetbmxrider · 10-26-2009, 07:13 AM

i'd like to see how the msd holds up too. kinda sucks it blew apart cause my rotor screws have red loctite on them

He is correct Opti is a great ignition system the only problem us LT1 guys have is its in the worst location possible making it a pain in the ass. If we didn't have to remove half the things in the front of the engine i'd say it would be considered pretty damn efficient
