Switching from Procharger D1SC to S480 BW Turbo ( condensed )

[Kellyo77]

Damn, you could have eaten a sandwich, as straight as it goes. Just smooth as can be. I believe she needs more boost to make it a bit more violent. lol! Make you work for that .50!

Just ask whatever about the ignition. If I don't know I can find out at work. The 7531 is what we run in all our cars. I have wired many of them. Granted we are a nitrous company, I can still find out whatever you need. More than happy to help.

The only thing I really haven't figured out is how to set the slew limiters when the tires break loose . 

It would probably be hard to explain unless I could actually watch someone do it .

Planning a trip to see Mickey any time soon ?      



But isn't traction control cheating anyways .   

[Donk]

Man, Good work on the setup.. that thing is on rails!!

Looks so SOFT in the 60'....

Hello aftermarket block in the future????

[CW25]

Have you tried the air shifter yet? I like that 9.64 run.

[RI85GT]

Wow Dave, excellent run........and video!

[PrecisionTurboMustang]

Awesome progress dave, I hope someday to have a project that could be as much fun.

[furchaser]

looks like I better start a build thread soon, I don't like to be known as a thread jacker.

I was just busting your chops , hence the lol.

Looks like we have some friendly competition down your way Dave.

He had some sort of ignition box interfeence with the air shifter, so he unhooked it and went about his business.

The 60' definitely calmed down nicely with the shocks set a bit stiffer. It'd been nice to seen if it could have handled 18psi that night, that track had it going on!

Got to give props to GM on the block, especially when compared to a 302..... I don't think you'd even get a "glory pass" out of an OE ford block like that.

Yep .   It shifted into second as soon as I let go of the trans brake .   I'm thinking it must have seen some kind of interference .

Thats the plan when its time for a rebuild .

Its been fun for sure .

Randy - how many leafs are you running in the spring packs? OE? What's the pinion angle? Once you get bars on it, I'd take it down to the two longest leafs only, and around 3-4* negative pinion angle.  PST out of Clearwater builds some great driveshafts for the money. I know of some big name 10.5 and radial guys abusing the hell out of their stuff w/o any issues. - Wish I could have stopped by to say hi, I was running around like a chicken with my head cut off helping a couple cars.

I have not checked any of that before  I am going to do that when the new shaft and yokes get here I would haft to check but I beleive it has 5 leafs I was going with caltracs after the first of the year but I am willing to do what ever can help me fore the time being I am getting Advance Driveshaft Specialess in Orlando to make me a shaft and get the yokes.I wish I could have talk to you at the track could you pm me your # thanks.

Did you talk with George ?    Get a decent deal ????

I saw the video , but I dont think this was the fast pass .

[rdakota340]

I am not sure the I thuoght there was someone in the other lane but I know something happened to them becuase I remember on the return road they were still going down the track but man did notice the wheel hop on that run  


Yea I talked to George with the yokes and drive shaft 437.$$ bucks not to bad he is making it out of 3'' tubing does your pinion yoke use the straps or the U bolts I took all the measurements last night to give him I might need you to pick up for me though if you don't mine so I can go and get it from you saturday.

[blown385]

U bolts .

No problem ......................... I know someone with a truck .

I wouldn't soften the leafs till you get the bars. They'll react better being softer(lesser leaves) but they'll be able to wrap easier(thus wheel-hop).

I have the big aftermarket u-bolts on the 'maro; it's going 1.teen 60fts, hoping for better this weekend. Check the pinion angle vs the driveshaft angle, you'll want around 4* negative angle. With leaf springs you can either put in wedged shims or cut the perches and re-weld.

^^^Thanks I will being checking everything when the shaft is done

Ive always heard you should run 3-4 degrees of negative angle on the pinion, what happens if you dont?

Hope like hell it doesn't make the perfect u-joint projectile. And  tear the ass clean off a th400 right at the bell housing.

Yea thats what I have been told they tenned to brake tranny tail shafts.

[Shagwell]

Incorrect driveline angles can cause all kinds of various gremlins/failures/damage.


Stole some more pics from N2S:







and just cause:

[blown385]

Yep .   It shifted into second as soon as I let go of the trans brake .   I'm thinking it must have seen some kind of interference .

Not interference ......................... more like ignorance .  lol

Launch light was still set on default .  (  3200rpm )   so as soon as I let go of the T-brake it must have triggered the " launch light "

Launch Light: This programs an rpm window that will illuminate the shift light when the correct rpm is reached for the holeshot. When the rpm is in this window the light will be on solid. If the rpm goes high, the light will flash. If the rpm goes low, the light turns off.



Anyway ............. I'm going to try it again .   Problem is , I need it regulated to 80psi for a quick hard shift .   If I hook up the AMS with this much pressure , I'm afraid it will use the CO2 too fast .  The AMS is always trying to reach target pressure , so it is constantly bleeding off pressure to do so . 

Any suggestions on a regulator that I can run in line on the AMS ???????

[blown385]

Stole some more pics from N2S:

Thats funny .................... I was just over there looking at them .

[slow67]

Use a 2nd regulator for the AMS to get it lower.

[mfpmax]

Thats funny .................... I was just over there looking at them .

And so was I!

[blown385]

This is the set up I came up with after talking to Sebastian at NLR .  

The switch will be used to go from track to street .   Basically when you flip the switch , it puts 12v to the T-brake button and input #2 on the AMS . It also switches from turbo pressure to CO2 pressure using a solenoid .

When the switch is in the other position it will run on stage 1 .  

When the T-brake button is pushed , it puts 12v to the tranny and the input #1 on the AMS .  




I think this is right .
