well, pulled the dynaspark after 4500 miles (cam swap time). the unit is still has no play in the bearings, and the o ring seal(its sealed to the timing cover) kept ALL the grit and crap out of it as they said it would.

so far, so good! two thumbs up...

I would love to say more, but no news is good news! lol!

 

ouch pretty expensive stuff .

 

I've had my Dynaspark in for about 3k miles (but do not plan to pull it to check jack! ).

While the price of admission is high, it is a quality piece of work, and very well engineered. I'm pleased. I just hope it works for a very, very long time.

 

what do they cost?

 

hmmmm well after trying the LTCC and being junk i think i might have to pick one of these dynasparks up! i dont think this stock replacement opti can handle 700+ HP NEMORE i was having nemerous problems with mine blowing up after 100-300 miles of use which i think was due to my cam dowel being too long soo ive cut it down and i will see how this opti holds up! if it blows i guess ill have to spring for the dynaspark

its gotta be worth it if jordan says! thats like siskel and ebert giving two thumbs up

 

that'll happen to any opti.. dynaspark or not...

I'm happy with my stock opti, 78k miles and running strong

 

Also running a 'dynaspark'. After watching my friend blow the ever livin' $hit out of his OEM Opti at the track last weekend, I'm glad I went this route.

 

werd thats what im saying! i mean im pushing a lot of power and all and i know how high tech these optis are but 100-300 miles before they blow i think it was that dowel! like i said ill just see how long this one lasts me

 

Due to an improper installation Werd!

 

my stock one has 230,000 miles and still no problems

 

You should be proud. Are you still running the original oil and spark plugs, too?

 

actually i have only changed the plugs once, at around 150,000.

the oil is a different story though. many many oil changes

 

Jordon.... if you're still checking this thread.....

How does the interior of the optical sensor section look, compared to the stocker? Does it appear to have better sealing? Is the seal at the harness connector upgraded? Does the bearing look like it will hold up better?

Would there be any way to reduce the "cap" to a simple cover, for those of us who only need the optical sensor?

I've been using a stock vented Opti for 3 years, but only the optical sensor to feed my MoTec/LS1 coils setup, and so far it has been faultless. I also know George Baxter's supported over 1,100HP, close to 8K RPM and lasted more than 5 years with the same setup. But that car was never driven in the rain.

I'd be interested in an upgrade if the bearing looked better, and the bulk could be reduced by reducing the height of the cap.

 

Fred, I can't answer the first question. This sucker looks extremely well sealed. I'd consider it a permanent looking seal. The harness is upgraded on both ends. The bearing appears to be upgraded but I can't be certain. DynaTech put some time and money into this work of art. I have the red anodized housing. With the machine work on that nillet alum, I could just stare at it all day it is beautiful.

 

Not doubting one bit..but Ill wait until you guys make it past the OEM level (~100,000miles) before I make any decisions. No way would I spend the extra cash if the lifetime is realtively the same. Glad to hear that they are beefed up over the stockers..maybe the route for some of the Anti-Opti people that keep chewing these things up.
