Kept the opti together for a few passes till she exploded again . I'm very happy with the way that the car runs, but I guess I need a Dynaspark or something better than the piece of **** Accel that I have. Here's my best pass...

RT .048
60' 1.625
330 4.680
1/8 7.255
MPH 95.48
1000 9.506
1/4 11.416
MPH 118.49

I can't wait to get a new opti and the car dyno tuned. I guess you can never get satisfied

 

Well at least your luck held up better than last time. Nice times. Hopefully it has even more in it after the dyno tune. Shame about the Accel, but that's not the first one that's done that.

 

Probably need to find out why your opti's are "exploding"?

 

Good times! How many RPM are you turing your engine? I'm turning over 6500 and also had some opti problems due to the RPM.

Also, what is your race weight?

the accels really dont like custom cams. my accel kept exploding also, and i finaly found the problem the accel shaft was an 1/8 longer then the stock opti. there was to much pressure on the rotor button. the first accel lasted 3 miles and the second went some where around 12-19 miles. i put the gm back in and now have about 1500 miles on it and got my money back for the accel. also make sure you have the flat hex bolts in the cam behind the opti. that was another problem of mine. i used the bolts that came with my cam and they had an 1/8 longer head. (that makes a 1/4" total)we got the bolts of an old 350 in the back and used them. and if none of that works then your cam is floating. great times by the way.

 

I'm turning it 67-6800 so far. The car weighed 3640 last year with me in it, but I lost some weight. Hopefully It's at 3590. I'll take it to a scale later this year.

 

I'm working on that Something is causing the rotor bilts to come out.

 

Thanks that some good info.

 

nice times.

 

Very nice times. Too bad on the opti failure though.

 

I just hope my Accel doesnt fail now.....

 

the way ur car is going - it will, thats why I got a MSD

 

Nice times/mph...I've never had an opti explode and I've been using the actual GM opti...But I'm not at your rpm either...Again congrats!!!

Thanks Alan, where do you shift your cam at? I don't know what is causing the rotor bolts to come out, even after loctite was added.

 

i am shifting at 7000 rpms and have no problems with the gm opti. only the accel. it really sounds like the same problem i was having.
