You should go lower than that.  Practice with different launch rpm's.  I can't launch over 800rpm or it goes sideways into 2nd.  Mind you I have crap tyres.

Are you holding 3rd gear or into o/d?  with 3.73 gears I would have though you could go into o/d briefly.

Mr69er, I do 13's and is older than a 90.  Can I get away without a skirt?  Don't make me spend more $$ and come down there and kick your high 12's azz!!  ;--

mrvett, there are alot of variables in getting a car down the quarter so don't consider that the be all and end all at this point (as a side note (and I am open to correction here) I hope you aren't using much more than around 4500rpm before shifting as when my top end was stock I found that didn't help).

Just check the basics like timing, compression, ignition and fuel pressure and then go from there.  With your gearing & mods and a good tune you have a fair bit more in the car as it is before you do any other mods in my opinion.

p.s. - 77CVT, I don't think any of the Ratpackians have set an ET starting with a 12 yet (not that I can talk). ;53

SC:
is it worth while trying to set up a day where we could check compressions and ignition timing
a lot of people forget the basic's  and there not hard to do
most people know how to do a comp test and timing but just dont have the equipment
the club is about helping each other well here's a chance
I can get hold of timing light, comp gauge and vacuum gauge and fuel pressure gauges
what does everone think

SC:
sorry cam for getting off the subject
its the rat packs fault
