My 93 camaro 5.3 swap 4l80e braking into the 10s ran 10.9@138mph @ bandimere speedway morrison Co, elevation 5800ft, got it dialed in to run a little better with this setup since the old tc78 gave out earlier this year, I went ahead and got the S475 billet wheel and changed the setup around, Im doing Denmah, 3rd gear mod so it helps me build boost of the line it seems to help since the week before I ran 12.6 @ 127mph without it launching on 1.5 psi of boost, with the 3rd gear it goes a little over 6psi, my question is has anyone that has done this mod experienced a drop in timing as its building boost? Cause the issue that Im having and should explain my shitty 60ft times is that timing drops really low as its trying to make boost and doesnt come back up until 20+ mph or so, I have efi live and can try and post the datalog if someone that knows can help out let me know thanks, I know once this issue is solved it should be deep into the 10s maybe lil faster since the trap speeds are pretty good.
Thanks, It was fun but I know once I get the timing issue figured out It should get a better 60ft and hopefully mid to lower 10s, hopefully someone that has had this issue will chime in
Im running a 88 Camaro back half car and im putting a 5.3 turbo motor in what all have you done to the motor
Nothing special, stock high mileage 188k engine, 799 heads ls9 gaskets and ls6 cam, the previous engine I was running I had the rings gapped this one I didnt touch the bottom end @ all.
Im doing a lc9 out of a 11 Silverado and im doin 243 heads ported turbo cam rods pistons and intake with twin pte 6062's. Im shooting for mid to low 9's with this setup and your setup gave me a lot of insight letting me know my goal is achievable

Yeah definetly your setup sounds like its going to be badass hopefully you get it figured out and everything works out
Go ahead and post your data log. My guess is that when loading up the trans, your going into cells which you typically don't get use which have some lower timing values in them. It also might be just that your getting more boost at the line, which are using lower timing cells. Not sure if you have checked for any torque management in your tune or not.

I will post it after I get home from work since I dont have my laptop with me, hopefully you can take a look and help me out thanks, Im sure that torque management is turned off but will doble check today as well.
