Here is the video of my car from the Fast Friday at Sunshine Dragstrip on Aug 21st. I left the tune the same as last months outing. I did change the rear springs in hope of lowering the car but it sits the same. Thanks to fat Rat 70 for giving them to me. They were a little shorter so I guess they are a bit stiffer.

On the first pass the car went to the left a bit and got a little squirrelly down track so I lifted. Lately my 60’s have been mid/low 1.4’s, my old best was a 1.40 flat and 6.25 @ 111 (which were not on the same pass)

60’ 1.385
330’ 3.963
1/8 6.248 @ 100.34

For pass 2 I had Darren (the guy with the Vega in the vid) help me adjust the anti roll bar to neutral to see if that would help it straighten out. It did

60’ 1.367
330’ 3.944
1/8th 6.146 @ 111

best pass ever ^^

Photo s from the above run




On the third hit I switched the nitrous over to the Steve Johnson tune up and solenoids. (leaner) same timing and fuel pressure. It seemed to hit harder and spun the tires and went right. It was hugging the right side and would not steer. I lifted and got back in but the car veered and I got out of the throttle again and wound up in the other lane just passed the lights. When I was going up for my next run found low air in the passenger side slick. I do not know how this happened as it’s ok now. But that explains the hairy out of shape pass. I also acquired a noise in the trans ( I think) which I had thought was a muffler coming apart previously so we put it on the trailer

60’ 1.455
330’ 4.074
1/8th 6.383 @ 98

I will be getting TRZ control arms for the front soon, not sure when they will go in. From what I see in the vid I need to tighten up the compression in the rear shocks, also I am pretty sure it’s driving through the converter as the shift light is staying on basically the whole track, though it may be something in the trans, or both.

Right now I am pretty happy with how the car is running as it’s running up to and a little better that I had expected.
Big thanks to TRZ Motorsports, Induction Solutions and Scotty Blakeny @ SPE carbs, Scotty fixed up the idle on my carb which has given me a better response and allowed me to leave at a lower RPM

Congrats on new best.

Wow, she's get'n it, Rob! Congrats.

Nice man..that sucker rips! Tell us about the combo??

[creeper72]

Congrats on the new best.
Love those 60" times - thats gettin it done !

[MadmanMark]

The car looks great and really gets moving!!! Pretty impressive speeds/times.

The slick issue seems possible. A low slick on the passenger side would drive it hard left when it left and then tire circumfrence would drive it right since the bigger tire is on the left side.

it's a 12.7 to 1 compression 049 head (ported) 468 Vic jr intake (ported) 850 carb
truck rods polished balanced ect.. factory steel crank, TRW pistons
comp flat tappet camshaft 262 270 @ .050 .630 ish lift ( I think it's too big at this point)
currently 4000 stall 9 inch ATI converter ( think it needs loosening) TH 400 trans
12 bolt rear 4:10 gears spool ect..
TRZ Motorsports rear suspension with anti roll bar

Thanks for the props folks, it's been a long time coming for sure.

How much juice? What's it un NA? That's gettin it done with 049's and a flat tappet!!

One thing I'll suggest is front end limiters. The alignment looks like it is being severely thrown off with all of the travel.

it's an .083 nitrous jet which is about 200-225 HP theoretically, so far the best run is with square jets in the plate and 6 psi FP (safe/rich)

It has been 10.66 @ 125 or 6.78 @ 101 with a different converter NA.

Thanks for the props

the TRZ control arms have limiters on them. I am not bothring with alignment ect till I change them. It currently does have some worn parts. The new arms will also improve the camber and should lower the front slightly.

pretty cool

New arms are a good idea. I found with mine if the alignment is off it was cause the car to wiggle around as one wheel or the other fights to be straight. When you get it aligned, do it with the car raised slightly to simulate the nose height going down track. When I set the limiters I crank them down until the 60' falls off and then leave it there. No reason to have anymore than the car needs. This helps at speed with aerodynamics and stability.
