What about boost and timing during the pass ?

turn up the boost, that converter will get looser if you can launch in boost

2.02 60' its not the 3k stall holding you back.

Launching off idle? You should be a full second faster with that mph

that was off the trans brake, it would only stall up to 2500 and was not even close to being on boost yet.. there is a lot more left in it for sure.
boost was 15psi with a 11.1 afr and pulled back to 20* on 116.

I don't think your converter is the problem. I have a 3k PTC converter as well and I can get it to 4500 and possibly more on the transbrake. What kind of timing and AFR do you have when your trying to get it up on the brake? Is your power valve opening too soon? Can you make any boost on the two step? Do you have an exhaust leak or charge piping leak? I would look elsewhere before you pull the converter.

thanks chai, at this point im sure its just the tc being to tight but I talked to spec right today and they will work with to get it right.. The good part is they are close to me.

I wonder if its a carb problem? PV,going to rich to soon? It must pull up to because its got some good MPH.

ya it runs good, afr stays good but the stall being so low at 2500 ish and with 3.25 gears it takes probably 100 + down track before boost hits at around 32-3500 then its gone.. Im going to work on getting a 38-4k stall and I already have a tick cam here Im going to put in this weekend. I also have a bw475/87/1.0 coming but that wont help with lag over this ching chong on3 on it now.

I don't know Adam, that sounds more like what a Chinese quarterback would say in the huddle. have you tried adding a little Soy based bio-fuel to get it lit sooner?
I'm going to plumb mine with one of Weston's spool valves and see if I can get a little better bottom end performance out of it.

Bone stock cars with stock tires can get better than a 2.02 60', If you have tires and a stall thats any bigger than stock you have another problem.

I changed the cam yesterday.. made a really good difference. Still will only stall up to 2500 but spool up is noticeable better. And has a nice idle to boot.

Good to hear.

I'd like to see some track times with the current stall and new cam. That way you get a true comparison.

Thank you Martin.. Im used to diesel stuff where you notice changes.. well I can definitely notice a difference with your cam compared to the 02+ls6 cam I replaced. Spool is faster, only about 3psi less vacuum but well worth the idle sound I now have.
Also I doubt I will have a direct comparison from track times because of the laundry list of things to change at the track. Besides it needs a stall to work right, working on a 36-4k stall so maybe I can leave with some boost and run the low 10's I want to drive off the street and rip off, then drive home.. Also I think the cage might be going in before all this happens..
