Subject: Re: My '91 on the dyno by dan0617 on 2010/6/25 17:09:27 Josh has given me excellent advice on launching over the years. He pointed me in the direction of positive camber in rear alignment, removing front sway bar, and snubber extensions on the rear. Those are my only traction mods other than tires. I doubt you need any of that yet, but once you up the converter stall you will. Quote:
This is a great starting and learning point but never yielded the results I was looking for. Quote:
This yielded me very satisfying results. Try about 20 psi in the nittos, bet you will end up at around 18. Quote:
Only had the balls to try this once, and it didn't give me any better times. I thought for sure it did, but it didn't. Felt VERY hard on my shit and I didn't want to break anything 1.5 hours from home at the dragstrip. Josh is king of putting it to the wood and worrying about damage later. Wish I could do that. I just can't. Quote: Next, back off the converter some, maybe bring the RPM to 1500 or so then wood the car to let the converter flash. This is the hardest on the car, but if the tire will take it this method will produce the best times. NEVER had the balls to try this, but I have a 2800 stall converter. Flashing a higher stall means something has to give. I now have a D44 so maybe I'll try this eventually. If you are running a stock or near stock converter this might work best for you. Quote: Edit - I just re-read my post and I come off like an expert preaching the 'right' way to do stuff. I'm not an expert, on top of that I have a 6 speed, and I have absolutely zero experience drag racing an automatic C4. The above is just how I think I would try to achieve what you are looking for, it may work well, work some, work a little, or not work at all. My disclaimer: Ditto. Only I don't have a 6 speed. Can we get an "Expert Opinion" in here? lol. Good luck at the track and keep us posted. I'm sure mid upper 12's will be yours. |
