That's not the coil. It's the Optispark which is an optical distributor. They're very accurate but were never properly vented and water tends to get in and short them out. This usually happens when the water pump fails which just happens to be located directly above the optispark (doh!). Anyway, my whole point to posting this reply is that he would probably know if his opti is bad as it will cause a quite noticeable miss in the high rpms (if the car runs at all). It's probably safe to say his opti is ok.CanadaStang said:The LT1 has a tendancy to have coil issues.[it's down under the water pump, and if water or antifreeze gets on it, it can cause the spark to arc] If he hasn't had that looked at for a few miles it can rob a lot of power. If they are running right they scoot pretty good. Unfortunately, the only one I've ever raced [on many occasions]had no such issues and pulls past me by the time I get out of 2nd gear.
Sometimes without the supporting mods (ie: heads + cam) some LT1 f-bodies (excluding the 93, no maf) experienced a slight power loss when going with a 80mm TB and/or aftermarket MAF. I never heard a really good explanation for this, mostly just speculation. Although, I admit that I didn't really care that much since my 93 was speed density and didn't have a MAF *grin*.Blue97GT said:also another question....HOW does the TB and the MAF on the maro make it slower????
but anyways....I HOPE I WIN!
You are correct, I was on the phone with my G/F while I was typing that last message,[brain lapse]Allen96Cobra said:That's not the coil. It's the Optispark which is an optical distributor.

LOL, I know how that isCanadaStang said:You are correct, I was on the phone with my G/F while I was typing that last message,[brain lapse]My brother has had to change his Optispark twice now [in only 50,000 miles?!?] in his 95', the 1st time it started missing, the 2nd time he was testing it with his G-tech Comp. and noticed his times were off, we did a voltage test at the plug wires and found that the voltage was down on 3 cylinders.Once again, new Optispark.[big bucks too] No miss, just low voltage.
Oh, I meant to compliment you on your 1/4 mile times, very impressive indeedAllen96Cobra said:LOL, I know how that is. Ick, that sucks . I was pretty lucky with mine. Original opti with 120k miles on it. Also, my water pump went out at around 105k and spilled coolant all over the opti but by some miracle didn't damage it. Yet some are so sensitive to water you could almost spit on it and short the damn thing out. Glad I don't have to deal with those anymore .

Thanks! I used to go to OSW in Orlando twice a week so I had a lot of practice. I only ran 2 12.8 runs ever and that one was an even 1.60 60'. It ran pretty consistant 12.9s though. My mph was low, it would break up in the high rpms but it seemed to only do it in 3rd gear. Never did figure it out. For some reason some of the 93's ran faster for some odd reason. Just goes to show you that when racing f-bodies you gotta watch out for those autos. That 3200 stall torque converter and shift kit dropped my 1/4 mile time .5 sec!!!CanadaStang said:Oh, I meant to compliment you on your 1/4 mile times, very impressive indeed
Very impressive!! And welcome to Stangnet, always great to have people who know their tech!!!Allen96Cobra said:Thanks! I used to go to OSW in Orlando twice a week so I had a lot of practice.

We'll see how I do with a stick, lol. Lets just say that I won't be racing anyone while people are watching anytime soon.

Ya, I'm not sure why my brother had to fix his twice, could be the driving conditions [he lives on an acerage, with gravel road] the 1st was likely b/c of antifreeze leak, but not sure about the 2nd one. I'm sure there is a reason, but I don't know what it would beBlue70 said:For what it's worth the Optispark was redesigned for 95 and was vented, I had no problems with my old 95

Tune is everything!DTMach1 said:um, you forgot the most important mod...a good tune...w/out a tune you're screwed
I'll try to find it but I doubt I will. It was almost 3 years ago. However, I should (hopefully) be able to come up with one of the MANY 12.9 slips I had. I'll search around my dad's place today since I just happen to be home in Orlando for ThanksgivingcodyGT said:I would really like to see a timeslip on a LT1 with those mods running 12.8 I don't see it happening. And it isn't beacuse it's a 93.
With those mods it isn't even par with a LS1.
