Dan Dishon's Transmission Den / Setting Two-Step Chip vs. Converter Stall

« on: July 04, 2015, 07:21:24 AM »

Hey Dan, Happy Fourth!  What is the rule of thumb for setting a launch chip versus stall speed.  In the shake down runs on my new FED, the car picked the front wheels at the release of the t-brake, set the wheels down and then picked them up again and carried them up for 20 feet.  It did not hit the wheelie bars to set the car down initially.  Your thoughts?   thanks

For those running the D2585 on a 12" rim at race pressure, what clearance is "safe" between body panel and slick surface?

Spud Miller's Cave / Mystery Solved But Not Sure Why

« on: May 10, 2015, 04:04:42 PM »

I mentioned my dilemma on the main forum a few months back, but wanted to report on Spuds forum.  My combo is not injected, but is a 422" SBC with a HRE sheet metal intake and a dominator.  Engine ran great on the dyno, then bolted into frame and engine won't idle.  I've been chasing the problem for months, I completely changed all of the Mallory HyFire VII ignition to MSD 7AL3 to match the dyno setup (no change).  Checked and re-checked all wiring in the chassis and re-checked entire fuel system, purchased a new carburetor, nothing worked.  Today, I took off the 2" up-style zoomies and installed the exact down style collector headers (borrowed from engine builder) that were used on the dyno, presto...the engine runs like a champ...idles perfect.  Anybody have an idea why the zoomies don't work?  I forgot to mention I also have a vacuum pump system pulling 12 Hg.  The carb would never get on the idle circuit, you had to keep hitting the squirters to keep it running.

Front Engine Dragsters / You Learn Something New Everyday!

« on: May 10, 2015, 12:41:20 PM »

This forum is a great place to learn and...vent!  I finally have a chassis and engine builder I can trust and they stick to their word.  So guess what, I got stuck by the paint & body guy.  He calls me the other day to inform me my panels are done all 8 of them for my shorty body FED.  I dropped them off Dec. 29th??? and I was quoted $50 / hr plus materials.  My father owned his own body shop, I've learned a little about paint work.  I figured any body guy worth his butt, can prep and paint these panels & scoop in 20 hrs. So I figured the bill would be between $1500 and $2000, wrong....he tells me I owe him $3700....which breaksdown to $1000 materials and $2700 labor.  Granted the color is a PPG special color and the panels are painted on both sides.  He said the buffing took a long time...give me a break.  Comments please...you can make me feel better or worse..I can take it.  P.S. - this is why I gave up racing 20 years ago, I see some things never change !!!!!!!!!!

« on: February 01, 2015, 12:32:56 PM »

Guys,
Is there a "rule of thumb" for determining a starting shift point from your dyno sheet?  Some people say use and rpm a few hundred before peek torque?  Powerglide, small block chevy combo...

thanks,
John

Dan Dishon's Transmission Den / Checking and adjusting PG band

« on: January 08, 2015, 04:22:12 AM »

Dan, what is the best method to check and adjust the PG band on a freshly rebuilt glide?  I've heard some people say "use a torque" value and some people say "4 turns method"?  and how often should it be checked?

thanks,

Front Engine Dragsters / Perplexed

« on: December 26, 2014, 05:48:10 PM »

I've been struggling with a problem for a month need some help...Engine came off the dyno running great idling great.  Put it in the dragster engine won't idle clean.  Three differences: the dyno has a 7AL-2 ignition setup, collector style headers, and a different fuel system.  Engine is a 15 to 1 SBC with HFE intake and a dominator.  The dragster has a new Mallory HyFire 7C ignition and zoomie headers.  I'm starting to question whether zoomie headers may be a problem on a carbureted gas application?  or maybe the new ignition has an issue?  any thoughts???

Dan Dishon's Transmission Den / Stock Case vs Aftermarket

« on: November 01, 2014, 04:58:18 PM »

Hey Dan,
At what point do you recommend an aftermarket powerglide case. I currently have a stock case 1.76 full length glide with upgraded internals with transbrake.  My dragster weighs 1450 with me in it, the small block chevy made 725hp on the engine dyno.  Should a stock case work?

Thanks,

Dan Dishon's Transmission Den / Powerglide Vent

« on: October 21, 2014, 05:53:01 PM »

Hi Dan,
My glide is a stock case glide with upgraded internals, my question is it has the stock plastic type vent cap, I see a lot of racers have a line in this location hooked to a tank?  should I go with that setup?

Thanks,
John

Front Engine Dragsters / To Drill or Not to Drill

« on: August 21, 2014, 05:02:14 PM »

New wheels (non-bead loc) tubeless slicks.  How many screws is sufficient per side of the wheel? Eight per side?  Also, should you pre-drill wheels prior to slick mounting or would this create problems with bead sealing to inflate?
