just put a glide in my 99 trans am 408 stroker 1.76 glide pro brake, 4.10 gear 9" rearend, steve Johnson black widow plate pilled for 300hp leaving on all on it off brake converter is ptc nitrous converter is stall to 4000 on brake... this converter was in my th400 then I went to glide just was going to try it in.. with th400 if went 1.25 60ft 5.69 1/8th now went to glide it went 1.30 60ft 5.78@ 120mph with electric shifter set at 6900rpm it just doesn't leave as hard as th400 . i know the first gear is different... do you think I need a 2 step and set it 3200-3500 it will help? or just sent it to ptc to get it restalled also trans has hydraulic fluid it in....

 

Get 2step and have it restalled.

 

I think getting it restalled should be your first priority. Having the converter spot on is even more important with a glide. What does the car weigh?

 

Definetly send it out to get it restalled for the glide

 

Race weigh around 3250...it a ptc converter where is best place to get it restalled..

 

PTC. I have had them restall a couple of converters for us and they never seem to dissapoint.

 

ok then

 

Any results yet? Have a buddy with a similar setup and trying to help him decide if he wants to swap from Th400 to glide setup.

 

yes got a 2-step set at 3800 and put type f fluid in it went 1.24 60ft 5.64 121mph still going to send converter off to fti..

 

Nice.
The lower you put the 2 step the harder it will hit. (lets the motor get a run at the stall point)

 

What rpm does the converter go to on the launch and what rpm drop do you have on the shift? I sent my converter to PTC to have it tightened 800 rpms. Got it back took the launch from 70% to 50% and it stood up and broke a limiting chain. After the broken parts are fixed I'm excited to get it back out.

 

haven't look at the 1st to 2nd shift drop thats what I got to see now....i know without 2-step on brake it stall to 4000... I set 2 step at 3500 only 60ft was 1.32 1.34 then set at 3800 It went to a 1.24. 1.27 got new slicks now 1.30,1.34 think it still to tight not sure

 

got converter restalled from lane @ PTC now on break it stalls to 3900 what should I set 2 step at?

 

So the converter stalled at 4000 before and now at 3800? I was thinking it needed to be loosened. What does the rpm jump to on the nitrous and what do you shift at and what does it drop to?

 

3500 is a good middle ground starting point.
Once you get it dialed in then try 3300 and 3700 and see if it likes either one better. Every car likes something a little different just need to find out what yours likes.

 

ok will do

 

lane @ ptc said he thinks it need to be tighter. I shift at 6900 but haven't watch gear change yet...

 

are you willing to share more of the combo. It seems to run very well

 

yea its a 408 stroker ported 5.3 heads comp cams nitrous cam 1.76 powerglide PTC nitrous converter 4.10 gear induction solution black widow plate pilled for 300 off the brake super vic intake ported..hyd roller lifters ,4150 fast tb 1 7/8 long tube to 3" to MF mufflers 3300lb with me in it 28x10.5-15 stiff side wall... its nothing really special can't wait to get 235cc afr heads go solid roller and get a 2" kooks header electric water pump and a vac pump and more nitrous

 

I agree with him.

You can also drain 3-4 qts and replace it with hyd fluid (hyguard) and it will tighten it another 100-200rpm roughly.
