New motor and Trans work (104-105mph in the 1/8).. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Super73 · 05-22-2011, 12:41 AM

I have been dealing with a few minor issues here and there and just got done with a fun day of racing in Dos Palos. This is the event where there are no clocks, 1973 and early, arm drop 1/8 mile. Traction is always a little bit of an issue because it gets breezy and it's dusty, but it sure is fun!!

If my G-tech RR is right (which it's consistantly about .1 and 1mph optamistic compared to the track), the two passes that I used on it looked like this:

Rolled in to throttle and did not have to lift
60' = 2.03
330' = 4.988
1/8 = 7.373 @ 105.25

Rolled in to throttle and had to peddle it about 60' feet out as it started to go sideways.
60' = 2.01
330' = 5.076
1/8 = 7.50x @ 104.12

Obviously I have to throw the ET out a bit do to the major traction issues, but that mph tells me it is making the power it needs to to go in to the 10's on motor. What's that old saying .1 in the 60' is .15 on the big end.. Even if it's .1 for .1, the first pass says it is there being it's gone 1.59 with out everything it had with the old motor, smaller verter and more weight (and a steeper 1st gear).

I have a few videos I'll post after I reduce their size a bit.

Very nice times! It sounds like it's starting out great!

djracer · 05-22-2011, 10:45 PM

when you make it to a better track and get the new times for your Signature?

Super73 · 05-22-2011, 11:52 PM

I am affraid it will not be before September. Truck should be getting dropped off in a few weeks for the cage, and I will be doing the summer school semester. Then we have a buch of things planned in August. Maybe I can get the truck rewired and get the N20 controller hooked up before September

djracer · 05-23-2011, 01:16 AM

what are you thinking about to control the nitrous and what type of wiring setup.

Super73 · 05-23-2011, 01:52 AM

I bought a NOS Launcher which with the single unit it will control two stages over time/percentage. It can control 4 stages with an add on and also kill the N20 based on a wideband reading (again add on needed).

From the looks of the NOS wiring diagram: http://static.summitracing.com/globa...s-15976nos.pdf it looks like the launcher grounds the noids (guessing based off a pwm).

I will run an arming switch for both stages then ground through the Launcher.
I will most likely have a relay running to the launcher as the activation from the trans brake.

I really need to draw it all up. Suggestions?

djracer · 05-23-2011, 07:46 AM

If you don't mind programming with a laptop look up the FJO progressive. I think its only like $220.00. Its easy to use and pretty cheap. My friend with the orange 67RS Camaro has one and its sweet. I have not played with these but they look like they may be made by Fjo. I used one of the older Nos units and it sucked.

Are you rewiring the entire truck?

99-LS1-SS · 05-23-2011, 08:25 AM

Wow! When you get traction out of the hole you'll pick up a lot! I bet that truck is a lot of fun to drive.

Super73 · 05-23-2011, 11:40 AM

Yes I will be rewiring the full truck. I bought a full universal harness that has 21 or 22 circuts so I can wire up the N20 off of it too (I'll use the power window/door lock circuts).

What N20 controller were you using from NOS? Sure hope this one works good..

Super73 · 05-23-2011, 11:55 AM

Here is a little video someone took on youtube.. I have finals today so I'll get mine up later.

Hopefully this works:

That was cool. Once you got off the line that power kicked in nice.

Super73 · 05-29-2011, 01:09 AM

It definately pulls harder than it did with the other motor. Wish I could have hit it out of the hole with everything it had, but that was not the case. 2nd week in september, hopefully I can..

I have 518 at the motor 284 lift cam. What converter would you suggest. Th350 trans

Not sure I am following you completely. I am assuming you make 518 hp on an engine dyno. As far as you cam specs, I'm assuming 284* duration, but at .006, .020, .050 and you are not stating lift.

Who makes the cam and what grind is it?

What RPM did you motor make peak TQ and peak HP?

*taank* · 06-05-2011, 11:20 AM

It's a comp cams extreme energy 284 hyd flat tap.
Peak hp was at 6100 if I recall
Peak torque was at 4500 if I recall
I can attach the dyno sheet later today if that would be best. It currently has a 2500 stall. But with 295 65 15 drag radials it leaves soft and won't spin hardly. It's a real fog off the line.

Super73 · 06-05-2011, 12:30 PM

Do you want max acceleration with sacrafising driving a little? Go with an 8" converter stalled to your peak TQ.

LUNATICS · 07-18-2011, 06:24 PM

awesome..im new to this forum, looking for some help with 60-66 style trucks, im setting one up to drag and play on street, was wondering if you or anyone else mind sharing info such as suspension mods

LUNATICS · 07-18-2011, 08:34 PM

i did read...lots of info in there, has anyone removed the entire front crossmember and stock suspension and install tubular control arms with coilovers , kinda like a mustang 2 setup?

softballnrd27 · 07-18-2011, 09:47 PM

New bern huh, I live in havelock and play softball in new bern. We will have to meet up one wekend.

Super73 · 07-18-2011, 09:58 PM

To answer your question, there are several guys with aftermarket fronts. DJ has a Fatman Mustang II, KP has a one off set up that he is producing and selling, others have made their own Mustang II front, and others are using aftermarket tubular arms made by Classic Performance.

LUNATICS · 07-18-2011, 10:16 PM

The softball guy..ive seen your 85 around..yeah we will have to meet up..think you got your truck from darren?

LUNATICS · 07-18-2011, 10:20 PM

Super 73..ive read alot of your posts...seems you got you sh*t togather! Way advanced for me...i had a 93 stang and let me tell you that is easy to get to hook up and goes straight...this "kp" is there away of contacting and get an idea of price? For me its all about the weight but primarily cost as well...i appreciate everyones input and advice!

Super73 · 07-19-2011, 12:07 AM

Look up kpeztruck on here. He has a thread in the racing section showing pics of his front end..
