My car ET's faster if the tires spin some
Only if they just spin a little bit though. It ran 13.1 if it dead hooked and 13.0 if I didn't heat them enough and they spun just a little.
I think it makes up for my lack of a decent converter. That leads me to my next question, 2800 or 3000 stall?

Re: My car ET's faster if the tires spin some
When it hooks up, you're probably bogging the engine down too much. A higher stall is needed. A couple of hundred rpm over your peak torque would be suggested.

Re: My car ET's faster if the tires spin some
I'm going to use the same excuse everyone does for not getting a "big" converter, it's a street car.
I'm not really sure where this engine makes peak torque, I think it's somewhere around 3400-3500.

Re: My car ET's faster if the tires spin some
i would think 2500 would work for a good compromise.

I drive mine on the street with 4.56 gears and a 4,000 stall. Sucks on the highway though hehe.

Re: My car ET's faster if the tires spin some
yep, a good lockup 3200-3400 would be perfect for a street car. You have a 700r4 right?
You can adjust the lockup mph speeds for the converter too in the PROM, so it will lockup sooner when your goin up hills or something. That way the trans isnt spinning that fast and wont overheat. I did this to my 2800 stall. stock it would lockup at 40mph in overdrive and part throttle. i set it to 30mph to basically idle up hills instead of screamin at 2200-2500 rpms lol.
Transcooler is a great idea to tho.

I'll look around for some 3200-3400 ones.

Re: My car ET's faster if the tires spin some
Like all these guys said, just run a lockup, a 2500-3000rpm stall would work well with your combo. Whats your 60foot now? Just looking quickly, I'd think you're under-carbed. What rpm/mph are you trapping at. Everything in your combo looks like it should breath pretty good, and then you've got a 600cfm carb to cap it off, I'm sure that combo would support a 750cfm vacuum secondary carb, or if you were to go with a decent amount of coverter a mechanical secondary carb. Converter alone would take you into the 12's, more carb would take you even further.
oh lol in that case that works too.

You're just a better 60' away from 12's, you've got enough mph. Converter ought to do it.

I just weighed the car. It weighs 3320 with me in it(160lbs) ready to race. Nothing has been removed except the spare and jack.

The car traps 108 mph, about 5400 across the line I think, it's hard to tell.

Re: My car ET's faster if the tires spin some
just swapping to a 750 DP would get him the 12's he's after consistantly. would'nt be quite as good on gas though, since the new found power would have the right foot working overtime
get that man a good convertor to go with that carb and bow, closing in on mid 12's

Re: My car ET's faster if the tires spin some
Looks like I have to go find the 3 or 4 gaskets I need to assemble my 750 VS.
This cam is starting to get boring too.
The converter would come first though.

Re: My car ET's faster if the tires spin some
Got the 750 together and on, car feels faster for sure. I've still got a little bog to take care of but I have an idea. I'm gonna go to the friday night test and tune this week and then to an auto-x saturday.

Re: My car ET's faster if the tires spin some
12.9 at 109, ran the same number 6 times in a row tonight. On street rubber to boot! 
A couple people said they were about 1 mph slower than normal too.
