Well if you were at the North vs. South shootout you saw the car earlier in the day sitting over a small lake of oil. The motor and blower torqued up so much on the transbrake that the oil feed fitting to the blower broke off in the head unit.

Luckily for me a number of expert folks were milling around and Intmd8 (Jim) from Speed Inc. checked around and found the fitting in one of Bob's home on wheels and an Easy-out kit. 15 minutes later Jim got up and told me it was ready to go. I topped up the oil and with the aid of KP cleaned up all the excess oil on the underside of the car.

At this point in the day it was too late for the car to run in the class, plus the car had still never seen over 4300 rpms with the FAST standalone.

After putting the car on the trans brake in the parking lot two more times I took the car to staging lanes and ran it three times.

First pass:

10.83@129? (lost the slip)
2.0
-I came out at idle and rolled into it
-shifted at 6400
-did not run out 3rd, it popped once and I coasted

10.38@129mph
1.65
-20 degrees of timing at wot
-I came out at 2000 rpms
-shifted at 6700
-lost the belt at 1000 mark

10.33@135.97
1.58
-22 degrees of timing at wot
-I came out at 2000 I tried to use the transbrake but let go before I brought the car to WOT
-shifted 1-2 at 7000, and 2-3 at 6800

So the car has a baseline.

I am getting married on Friday, but I hope to get a head start on my list of changes and tweaks by having the car moved at least once while I am gone.

Here is the list:

1) Take the car to Alston and have them make the Madman manual rack work on my car. I had them cut the rack mounts before but now the steering linkage binds. So I have the stock rack back on the car.

Have Alston redo the seat mounts. If you saw the car, the seats are too low and too far forward

2) Make the oil pressure gauge work. Yup still not working. Might put together custom gauge cluster with all Autometer guages including molding the tach in there too if I have the time and there is enough room.

3) Look into the belt/tensioner setup. Might be getting some slippage so I have been advised to look into running a smaller belt and I want to start measureing the belt tightness by using a torque wrench.

4) Run the car with softer shock settings, I had them on tight. Time to really run the car off the transbrake. My short terms goals are 9.80 and 140 mph. My longer term goal is to knock off Silver Bullet and then go for 9.50's. I may or may not upgrade to the YSi at some point. I'd rather do that then gut the car or loosen up my converter.

 

Sounds like a good goal

 

I think I can get pretty close to your mph but we're not sure how much the ET will drop with a transbrake launch could be a 9.99 or a 9.69...

 

Yea, get down to his raceweight and its all good

 

Trans-Brakes are strange. On Dad and Me's '66 Nova the trans-brake solenoid stuck two straight runs. Had to foot-brake her, 10.31@137. Replaced the 'Noid and next weekend went 9.76@141. I will tell you, the 'Brake makes it a LOT scarier. Nice runs, BTW.

 

I did two transbrake launches on the street last week at the wAREhOuSE and it was fun. I think the car is too heavy to really get crazy plus with my 2.48 first gear and 3.50 gear setup my car I think will be reasonable off the line.

From now on I will be using a torque wrench to tighten the belt and will measure my results. I plan to try 150 or 175 ft lbs the first time. I have it right now probably at less than 100 ft lbs.

 

On a well set up car with a properly set up chassis and part throttle to WOT tuning the trans brake will get you little or nothing. If your car isnt hooking and needs to shock the chassis or has a flat spot coming off of part throttle they will help but its only a crutch in that case.

If the converter needs to be loosened get it done now (or at least when the car is tuned 100%), that is the number one link between you and your 60's

Just put a mechanical oil gauge in your car somewhere, if you have a temp gauge why go through the trouble of a custom gauge panel.

Screw the rack, you can fix that over the winter - good exercise in the meantime. You drove the car so the seats cant be too bad

 

I had to drill out the front spindles a bit for the Madman rack so I want to put it back in for safety reasons. I did not try a hard launch since the stock spindle pins are now a little too small for the holes.

I don't think I have maxed out the mph of the car whatsoever so part of what I want to do is get the mph in the 140's.

 

I never much worried about mph in drag racing - sure its an indication of horsepower but getting the car down the track quick is what drag racing is about to me.

I was going to ask about the spindles, I picked up a madman rack and wasnt sure if drilling them out would lose most of the taper and make the stock tie rod ends unusable or unsafe. I dont want to ruin my spindles for 15lbs

 

I'm a mph man myself also. I would like to see 140+ also. Don't really care for ET's, since that can be had with BIG gears and BIG slicks. Takes HP for mph though....

Jose

 

Yes I had to open up the stock spindles a bit.

I might come back and immediately upgrade to the YSi and start questing for 142-145mph.

 

Bonneville is for mph

To each his own

 

At 3450 raceweight Kevin, what power do I need to make to run 9.50 assumming a high 1.3/low 1.4 short time?

One datapoint I have is a car (not LS1) that runs 9.dohs at 3250, makes like 825rwhp.

 

PSJ, our 2002 Silver car made 600-630rwhp to run 6.1 @ 111 in the 1/8, and a 9.71 @ 139 in the 1/4...at 3420 pounds. We made ~ 700rwhp, and ran a 5.9 @ 114mph, which is a 9.5 @ 142 or so. Thats all with 1.37-1.39 60's....come out hard, and you car is gonna pickup bigtime....ET and MPH. All your ET is in the first 330 feet...belive that I bet if you simply ran a 1.40 60, you car would prob run a 9.7 easy. Also......do you have a wideband on the car, so you can stay ontop of your tune going down the track?

Chris

 

Welp... there goes the car play!

Just joking... congrats!

 

If your rwhp numbers are accurate you have an easy 9.50 and down car IMO. Just have to get the 60's down. 137mph is like 600rwhp for your weight so I'm sure 140s will be there in good weather and a better tune. I would shoot for at least mid 1.3 60's, you have the power to run big mph so I wouldnt worry about that. If you dont want to restall the converter and you think its too tight hit it with a 100 shot and see

 

I spent some time going over the combination yesterday and I have come to the conclusion that I need to focus major attention on the belt/tensioner setup. When I went 136 I did not really tighten the belt as much as I hear the Renegade guys do. I will start measuring belt deflection.

I do have a FAST w/b and a datalogger Chris.
