Short video

[406shark]

I didn't have anyone at the track with me yesterday, so I don't have any action video. So today I had someone video me unloading it off the trailer.

wow that sounds sweet as hell man, whats the spec of your motor and exhaust?

[Bakas]

nice dude, gotta love those solid rollers! Mine sounds very similar but I have race mufflers. How did you do at the track?

nice dude, gotta love those solid rollers! Mine sounds very similar but I have race mufflers. How did you do at the track?

what kind of race mufflers do u have bakas?? i think i need to change my mufflers, i have some crayy mufflers that i bought at a swap meet brand new, guy said they sound like flowmasters but they def dont.

[OTHCUSTOMS]

hey 406, was that video clip even ran thru mufflers?

[406shark]

Nope, no mufflers on mine. Headman fenderwell headers with a couple of custom made turnouts installed.

The engine is a basic 355 smallblock. Check my project thread for all the specifics.

I'll post up tomorrow about my runs, I gotta get ready for work.

sound good shark sound like my old s-10, had a big roller ..280 at .050 and 680 lift..

[harleyboy]

glad to see the monster on all four wheels rolling man looks good.

[85SS]

Sounds real good Shark.

[OTHCUSTOMS]

wow 355, for sure i thought it was a 406, actually sounds somewhat like mine.

[XTEN]

NIICCEE!!!.Sounds like its ready to eat something.

[rayL]

did a couple plug wires fall off?? heh j/k bro sounds perty gud!!

[406shark]

The runs on Sunday went well. Not as quick as I'd hoped. It was very hot and humid, and the track was not the best for traction. I didn't have anyone to spot for me on the line. I was spinning off the line, but unsure how bad. My 60's were only in the 1.75 -1.80 range. I was running in the 11's all day. The times were very consistant considering it was spinning.

I attempted leaving the line anywhere from 3000 - 4500 rpm... no change in 60' times. I also ran the slicks anywhere from 11.5 - 13.5 psi... no change in 60' times. I knew the slicks were old (5 years), but was hoping for them to work better. I need to check the front brakes, they were not holding during the burnouts.
I didn't do any adjusting of the timing or carb at the track. I just wanted to get some runs under my belt with the package.

Next time I'll have someone with me to monitor for spin, and to video the launch to see what it's doing.

Hopefully the weather will be nicer as well.

Off to work...

get some new tires then see how ..was it hot at the track.track need prep maybe ..

It was upper 80's with high humidity... not the best for good et's. After talking to other racers at the track they tell of running 3-4 tenths off normal. I do know that I need new slicks, just waiting for some spare cash to show up in my wallet. I also want to make sure I get the right size tire. I'm still unsure if I want to keep the 28", or step up to a 29.5".

The plan is to run the current slicks one more time and try and determine after that what slicks to go with.

Thanks to all for the positive feedback.

Jeff

[OTHCUSTOMS]

im running a 29" tall slick, 29x12x15 to be exact, witha 456 gear, i use about 10.5lbs of air, about the front brakes, do u have a line lock? if not i would get 1, and right before you do your burn out throw in neutral give a few solid pumps on the brake and hold then put in gear and do your burn out. i thought the same thing at 1 time but after doing the few pumps its locked up nicely, also if you didnt already u may wanna switch to stainless steel brake lines. i got mine from lmctruck. with all the heat from the motor and the outside and wear and tear those rubber lines suck.

[406shark]

Yep, I run a linelock. This is the first car I've raced that had manual brakes and a linelock. I didn't think of pumping the brake pedal. I'll try that next time out. It will probably fix the problem.

I'm going to start at 12 psi, and work my way down in pressure until it hooks... or breaks something. :)


Jeff

[rayL]

line lock?? thats old school...bump through the water and mat it. If it hooks..then its ready! Admire the technique....

( Be unique, try something different)

[406shark]

I'd try it, if they would let me go past the tree on the burnout. They frown on it, to put it mildly at the track I go to. Are you running a glide? Sounds like you don't shift during your burnout.

Very nice run in the video...

Jeff

[OTHCUSTOMS]

i dont use the line lock at the line, i just use it for the burnout, i have manual brakes also, but rite b4 my burn out i pump my brakes then engage the line lock, at the line i just foot brake it, after my burn out i put in neutral and hit the gas a lil to clear out the headers, give like 2 pumps on the brake then roll up to the line, im tellin u with teh naula brakes the few lil pumps on the brakes works

I only use the linelock doing the burnout. I use the transbrake at the line.

Last weekend my routine was:

Pull into the burnout box, put shifter into 3rd gear (manual VB), push the brake pedal down, push the linelock button in, release the brake pedal, when given the go ahead I punch the throttle down and get the tires spinning (5-6000 rpm), after about 5 seconds I release the linelock button and keep into the throttle until the tires grab (didn't always grab), let off throttle and shift into neutral. Rev it once or twice to clean it out, shift into 1st gear and inch up until the pre-stage bulb lights up, then I reach up to the transbrake button and keep my finger just making contact. Slowly inch forward to just barely light the staged bulb, push in the transbrake button, release the brake pedal and bring up the rpm to about 1500, then when the top yellow comes on I put the pedal to the floor against the rev limiter. When the last yellow comes on I release the transbrake button and put my hand down on the shifter ready for the 1-2 shift.


Jeff

[OTHCUSTOMS]

ya that sounds all good, just rite b4 thery give u the go ahead for the burnout give a few pumps on the brake in neutral then hold firmly and press in the line lock fronty brakes should be very tight and have no prob holding...if u really still cant hold and your truck is pushing thru maybe u dont have enough water on the slicks or just loosing pressure in the brake lines, which like i said u should go to stainless steel lines sold at lmctruck.

1 thing though, u do your burn out in 3rd? u just leave it in 3rd? u dont shift it? i do mine in 2nd and shift to 3rd then release the line lock holdin pedal down spinning the tire up to the line. watch this video i have a good burnout on it.

http://www.youtube.com/watch?v=KiEB8vV6mMs

[406shark]

I was told that it was best to start in 3rd gear if possible, instead of shifting during the burnout. The truck has no problem spinning them quickly in 3rd gear. It doesn't need the extra gear to get them spinning.

That was a good burnout... it reminds me of my old Vette in the burnout box.

its a glide. The second i hit the gas i shove it into high gear.

I'll be damned. Starting a burnout in third. It works even with manual valve body. Sorry if it sounds like a stupid question, but thats the first I have heard of it. Also, running long tube headers, putting turnouts on the headers do you think it will achieve the same type of sound. That truck sounds awesome. Mine just loud as hell with open headers!

[406shark]

The sound has more to do with the compression and cam than anything else. If you run open headers on a basically stock engine it just sounds loud, not good.

I ran it down the track today, 12 runs, at the 1/8th mile track for a test and tune day. It ran good, but not quick. Either the guy I bought the truck from lied to me about the converter, or there's something wrong with it. The converter would only stall to 3000 rpm against the transbrake. The truck was a slug out of the hole. It was very consistant, 11 of the runs were within 7 hundreths of each other and the other run spread it out to 12 runs within 9 hundreths of a second. Just what I was looking for to bracket race with a chance of sucess.

If you go to "You Tube" and look under my screen name, 406shark, you can see the videos that were taken today. The camera work was NOT very good, but it will give you an idea. The video labeled 1st run... http://www.youtube.com/watch?v=0ModPyONdlY&feature=channel
has a hell of a burnout, I pumped up the brakes... and the linelock held, but it stuck and took a while to release. The following burnouts were without incident. I had my friends wife take 5 videos, and they are all up right now. My friend said next time he would do the video work. :)

I have to do some research and maybe buy a new converter to get the rpm up to where they need/want to be.

Cam is a crane roller .314 lift and .574 dur with 12.5 to 1 compression.

[406shark]

With your cam and compression yours should sound close to mine. What is your timing set at? What do you have your idle set at?

I have my timing locked out (currently at 35 degrees total). My truck idles right at 1200 rpm. I have fenderwell headers, and if you run them in ANY kind of dusty enviroment it kicks up a dust storm. That is why I made up some turnouts to get the exhaust out the side instead of pointing at the ground. It actually sounded a little crazier before the turnouts were installed, but it wasn't worth the dust storm that followed me around.

There was a guy at the track yesterday with a gen 2 S-10 with fenderwells. They cut the grass before the race and he had pieces of grass everywhere after firing it up. In fact he wasn't allowed to run until he drove around the pit roads for 10 minutes to get the grass cleaned out from the truck.

Jeff

[406shark]

Almost forgot...

He only recommended starting out in 3rd gear because of my manual valve body. He said the act of the transmission shifting while the tires spin can cause problems.


Jeff

[td7172]

My timing set 32 total and idle at 1200-1500. With the cam, she bounces a bit. I like the idea of starting in 3rd, easier to get to nuetral quickly to clean her out. Thanks for the info.

[chris1972]

nice sounding truck shark what was the times and 60ft...my old truck was a little slow of the line i installed a 4500 stall got better times and 60ft

[OTHCUSTOMS]

shark, u said you are leaving the line at 3000 on transbrake? def doesnt sound like it at all, this is just my opinions from watching your video, you can try it or uyou dont have to. 1st off when u go to get the tires wet in the water box id get the back tires in there n give a lil hit on the gas so the tire gets a little spin in the water ( just give a tap) so this way the entire surface gets a coat of water, in my opinion it helps spin the tire at burnout easier and get a nice warm up on it. 2nd as for that converter something has to be wrong, i dont even have a transbrake i leave totally off the footbrake and i get mine up to 3000-32000 just on footbrake alone, and it sounds louder than yours. i have a ati treemaster 3000stall 4500-5000 flash. try the same as me, do your burnout, after that clean out the exhaust in neutral, give a few pumps on the brake again then put in gear, roll up to the line you should still have decent pressure to hold the truck when applying the brake soon as u engage the 1st light for the tree to function hold the brake tighter and give some gas bringin the rpm up and ever so slightly inch up to activate the 2nd light, also tryin to give a lil more gas, see how high u can get the rpms up withoutgoing past the line. like i said im do it at 3000-3200 all on footbrake and it sounds more radical than yours. heres a short clip of me all on footbrake

http://www.youtube.com/watch?v=nJ1i189i8Os

[406shark]

Yep... something is wrong with the converter. It will only stall to 3050 rpm to be exact. It stalls at the same if on the t-brake, or foot brake. I just got back from the shop and tried a couple of different methods. The memory tach shows the same stall no matter what I do. I set the rev limiter to 2500 and tried, it only allowed it to come up to 2500. I thought maybe there was a problem with the rev limiter... no such luck.

The converter is bad. I'm going to take the truck to the chassis dyno later in the week to see where it makes its power so I can get the correct stall converter.

Everyone is telling me to just run it this year and enjoy the consistancy.

Jeff

Yeah you could do that and when some money with it. BUT you are a racer and racers always want the best they can get out of the race cars right.:naughty: Good luck with it. You will get it there.

[406shark]

nice sounding truck shark what was the times and 60ft...my old truck was a little slow of the line i installed a 4500 stall got better times and 60ft

7.502 - 7.584 for all 12 passes.

60's were 1.762 - 1.796 for all 12 passes.

The pass that I left the line at idle went the 1.796, all others were in the 1.762 - 1.779 range.

Like I said, it seems to be a consistant package at this point. I haven't even done ANY tuning of the carb, timing, tire pressures, suspension settings, etc. I'm almost scared to touch it! :)

[406shark]

That's the rub. I want to get it into the 10's, but worried that it won't be consistant after spending the time and money on it. It was built to be a bracket racer after all.


Taking it to the chassis dyno just to see what's going on with it. I'll update when I know something, probably on my project page.


Jeff

[OTHCUSTOMS]

if there is a problem with the converter u dont wanna run it like that, do u have your cam card??? did the guy u bought the truck from give u the card for the cam? if u call ati all they will ask u what u wanan use the truck for how much it weighs the specs on the cam card what size tire and gear what kind of trans and they will give u the exact converter u need, . i messed up ever so slightly i told them i do drive on the street very little which i really dont anymore, i could have gotten a bigger stall but for me sayin slight street use they said 3000 stall. but still im very happy with how my truck progressd.

[406shark]

The plan is to bring the truck down and get it weighed tomorrow. Then bring it back to the shop and pull the converter and run it down and have the converter cut open to see what's going on inside.

I'll update my build thread when I find out what is going on.
