Default Solid Rear - Take your guesses.....

GOing to be hitting Pittsburgh tommorrow night after this past weekends plans were spoiled due to no babysitter. Has replanned for Beaver on 6/7 but they just changed their schedule to a major event....not a good time to be testing your new setup out. Need some shakedown runs before blasting it FULL TILT.

So what do you think it will run? The setup should be a great A-B test of what the IRS is costing us in power. My best short time was 1.37, and the car all last year went about 1.38-1.40 depending on conditions. If she cranks off a <1.37 then I should see some nice gains at the end of the track. My normal slips show a 2.5 times improvement at the end of the track for anything gained in the 60'. In other words a 1.40 to a 1.38 would be about .06 at the end of the track.

Insanity is getting low 1.3s out of his setup, Outten was crankin out 1.28s, and some others that shared information along the line were getting 1.3s with much smaller CI motors.

I am a bit on edge about running the car after such a drastic change. On the street its beautiful to drive, and no signs of anything out of kilter, even under heavy throttle you can let go of the wheel and it goes arrow straight. My IRS used to pull a little under VERY hard throttle - this puppy just SAILS.

Instant center is set at 44" out and about 4" high. That is about 4" back from mid wheel base and maybe a little higher than some would recommend.

I feel like the night before christmas when I was a little kid.

I'm pretty sure they're talking about 60' not the reaction time.

They are; chucks88 was being funny .

Low 1.3s if nothing else breaks Are you going to make a full pass, or start out with a few launches to half track or so?

Should go low 1.30s

Be careful on that first full pass, not only on the launch and at mid track, but be ready when you let off! Some guy's get a little carried away with their settings and forget it'll act differently when you snap the throttle shut and unload everything.

Good luck Jesse and be careful,
Dave

I hear you Dave.....I was going to call you tonight, but ran out of time....just got in and have been going over the car since 4:30 this afternoon.....just making sure everything is ok and ready to go. Insane that you can spend 6 hours just checking thing on a car that you work on ALL THE TIME. Meanwhile you just jump into the family vehicle and run it without a second thought.....guess your pushing it a little further with these rides though.

Yeah I hear you about taking it easy...that is why I am going to a T&T so I can just ease into it and see what the thing is going to do. I will probably hit it hard off the line to see what it will do, then take it easy the rest of the track - maybe just easiing into it and like you said, leaving off at the end of the track and be a HAIRY feeling. I know Dads car before used to do some SCAREY stuff before running the radials. (which is what I am running now too 30x10.5 hoosier drag radials.). They are SUPER stable on his car now and should work well on mine too. I drove it tonight up the back road by the house and hammer on it a few times and I think it pulled the front end on the one Higher speeds feel stable. Another reason I think going to Keystone is a good idea, since they take SUPER SUPER good care of the track even on T&Ts.

Talk to you all later...and I will update you all with the results. I will be happy if it goes 1.3s first time out and everything runs smooth.

As for the weak link now......THERE ARE NONE! (probably driveshaft, but that has latest for YEARS and no more power is being added so I should be safe) knock on wood.

The car is CRAZY stiff now....I can jack up the rear of the car in the area where the stock jack locations are designated and the entire car lifts off the ground an equal amount on that side.

Once I get more comfortable with the TIG welder; I am going to add some bracing down off the roll bar too, not so much because I think it needs it.....just for fun

With all that power and hook, I would have to say that your underwear is going to be the weak link.

Good luck and I hope you run low 1.3x or maybe even a 1.2x

Yeah tonight as Pburgh is where we will be. Gates open at 5:30pm racing till ~10pm

crossfire...no the "wear" will be fine - I am used to big wheelstands and LOTS of power - went down the track 180ft staring at the sky on this run. When it touched down the car was going near 90MPH. You just watch the white line out the side window and make sure the line is not getting further away or closer - if its doing either then you have problems



I don't think the vette will do that sorta wheelstand - then again if she does - hopefully its straight down the track!

Jesse,

Before you get carried away on the rollbar mod get in touch with me! I just went thru NHRA & IHRA chassis cert. for 9.99 and faster a couple of months ago and there's an issue with C4s & C5s.

Even though we have a huge frame behind the driver, you can't attach the rollbar main hoop to the kicked up section of the frame under the halo! Seems like NHRA decided the picture in the rule books of a rollbar/cage must be attached to the frame BELOW the drivers seat to certify! Wheelsup had to redo his main hoop in the cage and extend it to floor level in order to be certified. Luckily when I did my car we tied the 4-link brackets into the main hoop so I was down low already.

Good luck at T&T, I'm taking the '66 out today for the first pass since breaking a rod early this year. I'm signed up for PINKS at MIR this weekend and have no idea what the car will do with a new combo in it.

Be safe,
Dave

FD,

Thanks, I'll do my best!

BTW, I'll be heading to Fla soon to scout out drag strips, I mean houses, what tracks do you go to? Where's a central location to the most tracks?

Dave,

Yeah i got your message from before regarding this......and I checked mine and its tied into the upper area Not quite sure why Leo at neverlift would have done this being they are a certified shop for such things.....

At any rate, could it just be the guy you went to was **** about this....I know I have run into a few at tech that said my car was totally illegal for the swingout bar with the inner slide, they wanted it pinned - somehow they thought a 1 5/8" tube inside another tube running up into one another 3-4" was weaker than a 1/4 pin going directly down through. that was until I pulled some others into the discussion and they set the guy straight. Also had instances they said the IRS was illegal, but were basing everything on the C3 designs.....and wouldn't you know it; first F'in run I broke both spindles! Got to show the guy up close and personal that the wheels stayed secure

Your guy might be dead on though - does the rule book show diagrams of the C4 and C5s? Or is an interpretation thing?

Oh well one more reason buying a TIG welder was a good investiment for the future...why pay someone else 2k to do the work......sounds like another winter project. Damn just wish I had the time to do everything.

and PINKS! Are you for real? I would go on the show with somoene elses car, but not one of my own. It boils down to who is the best liar. I personally would throw a switch in the car that you could activate (under the carpet or something that would cause the car to misfire real bad upon returning to the pits after a run....that way you could claim damage and get some lengths)....a way to produce smoke out the pipes would be good too......The key is to just barely take the stripe, which any bracket racer should be good at.....that and be loud and lie like a ****. THe kids and I watch the show for laughs....now I catch the wife watching it on the TIVO.....slowly buy surely I am brainwashing them ALL!

It's PINKS All Out, nobody loses their car but the winner of the 16 car shootout gets $10K! They pick a field of 16 from all the cars that enter, and run at least a group thats close to one another ET wise for a no spot, head-up race.

About the rollbar main hoop, the local guy flunked it, the chassis builder appealed to the Div. Tech. Insp., he upheld it and it went to NHRA Hq. and they upheld it! Rulebook was written for no-frame Camaro, Nova, Duster types most likely. I believe it actually started with one of the fast C5 racers at Etown (can't remember who but it was on this forum), try a search 'cause it was a big deal.
