Why leaving at such a low rpm?

I was running 7.0 index and it left good there and ran pretty close . I have footbrake race all year long and .4 pro tree had a stepp learning curve for me . I rnded up #2 qualifier with a 7.0103 . First round made a 1st to 3rd shift and waited for the guy to fender me , which he did . Stupid me not only missed the shift , but forgot to arm the nitrous system. When i went to drive around I had no spray . They are are running NMRA today and have a footbrake race . Wife is pissed right now but i am ......already loaded from last night so we will see.

[hotrod 80]

Well , went a couple of rounds at NMRA/NMCA and ended up next to a dude with a 70 Mustang . He went .001 and 8 numbers over i was slower on the light and went 1 number over with a 7.08 on a 7.07 . Trailer time as i was already in hot water for testing friday night racing saturday and then sunday which was my mother-in-laws birthday . oops .

For an update . I pulled the drum / drum power assembly off and added the Mopar master cylinder . I am not real hhappy with it at this point . Seems like alot of pedal effort and not enuff travel . I will call Aerospace brakes monday and see what they say .

[Marv D]

I used their master on both my Nova and the truck,, Actually on the truck I used Jeggs version but is the exact same as the Aerospace,, possibly same supplier of the casting?? (Don't know that for sure but wow are they identical)
Anyways
Nova is Willwood 4piston disks up front and Aerospace 'race' version disks in back,, truck is stock 70 GM truck MANUAL disks up front and Willwood 4 piston disks in the rear. It took some SERIOUS bench bleeding to get all the air out so I had a solid pedal. I had kida the same issues your talking about... somewhat mushy pedal, lots of travel and what seemed to be a LOT of foot effort to get less braking than I had with the stock manual m/c.

Aerospace told me to take it off and bench bleed it again. I argued that I had but did it anyways.... then I shut up because I had really good brakes afterwards LOL

The pedal effort was still a more compared to the old big bore stock m/c. But getting the air out made a big difference, and I got used to it real quick. Now I can make the first turnout with EASE coming down from 117+ in a 3550# truck.

One issue I had with the m/c.. be SURE the caps fit correctly and are tight. I lost one of the caps in a big wheelie, slopped hydraulic fluid all over the headers and thought I had a engine fire, what a smoke fest!!! Actually I probably don't want to know how close I really was to a mid-track fire! Anyways those plastic caps arent real secure,,, just check them once in a while.

I bench bled the crap ouyt of it then put it on the truck and added hoses to it back to the resevor . The pedel is firm . I also used my vacuum pump to pull the fluid through til it was almost perfect . The fluid that was coming out had a dark tint to it like a seal was wearing out .

[hotrod 80]

Got this figured out . My pedal ratio was 4.65 to 1 . I bent the rod to square it in the hole and moved it up the pedal to create a 7 to 1 ratio . Much better .

[hotrod 80]

Hey Marv , i took some pics of it today to give an idea what is going on . Here is the underdash shot of the areospace brake rod after being cut to length and bent to fit . You can see were i took a piece of plate and cut it to fit the 4 holes from the old booster and the 2 holes and rear of the new booster . I tried to offset the master to the side . I suggest just centering it .

I couldnt get the truck on the converter at all before . At 1800 it was pushng through . I didnt have enough leg to hold it . Now i can bring it up to 2500 . I typically leave at 2200 anyway . It hits the converter harder there .

Random interior picture , but i swapped the pro stick to a pro ratchet . With the new converter it like to pull wheelies . I have been paying more attention to driving than shifting and just smacking it from 1st to 3rd . This new shifter will fix that . Working on a shift noid set up .

You will like the ratchet,, just keep yur hand off the shifter at launch,,,
I learned,, when you start leaving hard,, the hand just sorta flies back and grabs a gear for ya. Actually hate to admit this but that was when I discovered my pile would be quicker with a glide...

I dont doubt it would be quicker and tamer with a glide , but with christmas and college it will be half next season before it is in the budget . Meaning buying a good glide . I could probably get by with a stock case 1.76 , but want a good one . If a deal pops up on one ill get it and deal with the wife after the fact .

[hotrod 80]

Went to Lonestar motorsports park in sealy texas today for a gamblers race . Ended up runner up . Worst light all day was a .044 which was in the final . Good finally for the year

[hotrod 80]

Well the Summit wheels didnt work out . I finally had time to pull one of these out of the box and they are Chinese and heavy . Sent them back and ordered Billet specilties streetlites . Not much done today except swapped the passengerside rubber and driverside polly mount for solid mounts . I bought a polyurethane trans mount on the advice from my transmission guy .

[hotrod 80]

This is what i ended up going with . The summit wheels ended up being built offshore and heavy . Every pound of unsprung weight is like 3 pounds of unsprung weight . This would be like adding 100 lbs to the truck . The new wheels are 15 x 4 2.25 backspace in front and 15 x 10 rear with 5.5 backspace in rear . 165/80R15 front tires and 28 x 10.5 x 15 M/T slicks 3055 S stiff sidewall . New lugnuts and tubes . Starting out next season with fresh rubber and hoping to not change anything .

Like the new wheels bet it will look killer. Did'nt know Sealy was open anymore this year and congrats on the finish. A .044 worst of the day , thats way better than any of my best recently. Maybe should put you in my drivers seat.

This thing just kinda popped up . I heard about it the day before . Still had to go 7 rounds . Sealy is also running an IHRA 6 race series next year for there bracket program .

Thanks for the congrats , finally getting this thing to work .

[Marv D]

Yhis has been a realitively short build!!! Final product looks very Cool! Time to go kick some booty!

[hotrod 80]

Thanks , Marv . Been alot of work and many a long night . This will be my first season going in with a truck that is working already . Last year i was messing with chassis and drag radials between rounds . It would go out and spin and i would spray the difference back up after i heard throttle chops . That worked pretty good for me . I would go back to the pits and adjust and repeat the same thing . I believe i got all that worked out this year . Should only have to go out and drive , well after all the work of loading and unloading .

Looks like here it will be simialr to IHRA now with box and no box classes . Last year was a true no elctronics "footbrake" only and full on electronics class called "super pro" . It appears that this year in no box trans brakes and 2-steps will be allowed in "footbrake" . I believe it is this way in the rest of the country and other divisions . I personally dont see an advantage to a transbrake over footbraking without the delay box to move reaction around . The 2-step would ensure that you leave at the same rpm everytime . Thinking im gonna start a seperate thread on just this subject .

It's simple
MASS!!!!! I can move my thumb a lot easier, more reliably, and more consistantly than I can my big ol pfhat leg. ROTF,,

But seriously......
I don't know how much there is to this,, but there was a lonnnnnng discussion some time ago over on the bullet (geeeee go figure that YellowBullet had some HUGE thread on any topic!) ) anyways, the discussion was about Left brain / Right hand, vs Left brain Left leg. I won't pretend to remember or even understand all that was going on in that discussion,, but it 'seemed' like there were some pretty smart, knowledgable people laying out facts and figures. I can't find the thread,, might have even been long ago enough for it to have evaporated in the meltdown when Monty moved the site.

I know we have an artistic - creative - illogical - whimiscial - non conformist - irrational side of our brain (let's just call that our femmmmminin side LOL) and a side that controls logic and functional things like sub-consious muscle function breathing - heart beat - flight or flight - basically 'reactions' (you run, your muscles scream for more O2, you breathe heavy and your heart beats faster - harder without 'thinking' about making it happen. That side also controls things like reactions to the eye seeing light,, making your thumb / leg / foot react.

All I really remember out of it (obviously because it was all that applied to me and was what I wanted to hear...) Left brain, right arm-hand-thumb. That is the most common, consistant, and trainable motion.

And for some reason it shouldn't be a 'thumb' motion, it shold be a 'BODY' motion for consistancy. You don't grip the wheel and pop your thumb off the button,, it should be OPEN HAND, thumb on the button and release with a shoulder / elbow / wrist / thumb motion,,, THAT was the most 'time consistant' motion.

Also your thumb should be up in your field of view or perriferial view at least. Somewhere close to the path of the eye to the light.

I brought up "how can that be so set in stone,, we have left handed people and people who are more logical than artistic",, and vice versa.. well you know th ebullet,, I was bi*tch slapped around the forum a couple of times and basically told to shut up, listen and learn LOL.

So why a transbrake,, apparently your brain and body can be more consistant

The rest of it is just training your brain for the 'when' part!

(sorry for bad spelling and typing,, ina hurry this morning)

Good stuff . This is what i was looking for

[hotrod 80]

Weekend started out crazy . My Powerstroke had the pickup fall off in the tank . I was working nights all week , so friday morning at 5am i get home and start dropping the tank . Had it on the ground by 7:30 and went to bed . Got up around 11 and started the "hutch" and "harpoon" mods to fix Fords better idea . Finished that up about 4 pm . The Luv is still on jacks in the garage . Finished the rotor and cap install and got it back down on the ground ( somehow i galled a lug nut and stud on paas rear so i replaced them ) . Started to load the enclosed and head to the track . Got to the track at 8:30 pm . This place was packed drag cars everywhere and it was street car night on top of it . Got 2 test hits in and i was feeling really good as it went .012 & .021 off the trailer 6.95 backed with a 6.96 . Loaded everything up and loacked the trailer up and headed home .

Saturday morning . Ready to race . Have my buddies kid crawl into the truck to pull it out of the trailer and i gues he hit the linelock button with his knee . Line lock coil burns up so bad the plunger o rings melt . 2 good time trials and into first rounds . Just a note only 3 guys on transbrake as this was just announced tuesday and still may not be final when the new director of Div. 4 gets in place . First round win , second round win , but the tach quites and it's done . Fourth round i get back and i have oil drips . i clean it up and im still going . Lights are decent , but not there yet . Anyway oil down and we sit for an hour . Cold brakes and i creep in to deep and go .014 red in quarter finals , but a good fist outting . Almost 100 cars

Sunday , Got line lock kit i bought for the White Luv , my old tach off the shelf , a few odds and ends , fuel , breakfast tacos and headed out . Found passesnger side valve cover gasket broke and replaced it . swapped tachs , and replaced the entire line lock and bleed the brakes . Good to go except left knee swollen from impact with roll bar sat . Got to the lanes and over here people talking about the new transbrake rule . I index race off a brake , so what the hell . .010 first hit . Went to 11 cars and got out run due to weather change and not taking dial out . Had a good weekend and im getting things lined out .

I work with a guy that was out there racing. He drives a red mid 80's camaro with a little sbc. He was talking about how no one including him was told there was anychanges and all his paper work says super pro and footbrake are the only classes.

Glad your truck ran good. Hope to be out there with mine in the near future.

I ask the same questions . All my paperwork said footbrake or super pro . They said they didnt have time to change it . They also said they had a drivers meeting the 16th and i was working . The way i understand it is it is now box and no-box or E (box ) and NO-E

Race 3 & 4 this weekend . Also added shifnoid and MSD window switch . The window switch can be adjusted in the lanes vs. being forced to use the laptop . I had to adjust the cable and make it was not bound up . I fire a S 55 relay with the msd digital window switch which fires the solinoid . The shifter is new and i carpeted it to mak it near invisible in the cab . I still have to have door panels made and paint the inside of the doors flat black . We will see how these changes work this weekend .

[hotrod 80]

Quick update , got to 13 cars saturday and got tree'd and broke out , but got to 7 cars sunday and went .119 red in the quarters So i got some of my money back . The left lane was tricky for some reason . Alot of .100 plus reds and 60' numbers would swing like .03 for most i talked to . The truck really was trying to print slips . 6.945-6.998 ( i chopped once on the 6.99)

Shift noid was working ok saturday when i got outrun . I had the solinoid tied into the hot side of my S55 relay for the nitrous and then the power daisy chained off the shift noid hot side . This caused a voltage drop when the shifnoid "hit" causing the window switch to drop out and restart . The window switch has a start sequence that shows on and off and cylinder count before it becomes armed . Once powered down it takes a while to be re-armed . I fixed this by tieing the power from the window switch ( low amp draw ) to the Nitrous S55 and running a new power wire to the starter solinoid . The starter solinoid and the Shift noid are non coencidental loads , meaning they wont be drawing amps at the same time . I also put a fresh S55 in for the shifter just to be safe . BAM ! hits everytime . The shifter set up made the truck a tenth quicker . The MSD digital window switch and the auto meter tach read different rpms . The tach is slow . I have been shifting late due to the tach/shift light . I set the shift light 100 above the shift point and use that for something else now . 7.0 index racing this Saturday and maybe 1/8th mile footbrake at sealy sunday for $1K purse .

Your gonna like the glide (is it t turbo input or are you doing a new converter?)

Only down side is now your looking for a new shifter. Lots of good glide shifters out there in both air and solenoid.

Headed to a race in Tucson this evening myself. First points race I've made all year (so far) See if I can't clear out some of the cobb-webs and rust (in the drivers head that is LOL)
