Yeah, that pass i was horsing around, and upped it from my racing 3200rpm stutter to 4400rpm to see what it'd do. i may turn the box up as high as it'll go one day with exhaust off and a small nitrous shot and go for my bumper dragger....some day LOL!!! Typically on race day it only pulls them maybe 8" or so and carried them to the tree, this pass i had that sheeot eating grin, belly rolling laugh..out loud..seriously, and a whoo hoo before she set down LMFAO!!!! you guys know how you can feel .01 +/- in your 60'...this pass was .05 so it really hit me hard/set me back in the seat. It was fun, nice part is she leaves nice and flat, driver herself right down the center of the lane and sets down nicely, everything i could've ever asked for.

Re: Nice launch picture

Damn, looks greta, i was going to launch the hell out of the new motor when the Dana 44 and T56 went in but i hear it is not a good idea on a scat 9000 crank. So, when the 408 is built 100% gorged i will really get to stretch it out and stand on the back tires.

that's not going to happen after this guy butchered my heads and installed this POS comp cam. I'm .3 away from where i was with this engine before it blew up, so there is no way i could find another .5 unless i got these heads fixed or just installed new ones with the bullet cam i had in here originally....but i have waaay too much in these 23* heads after inital purchase and then having them "fixed" to stick another grand in them to make them right right again. The cam, i dunno, i'm mulling that idea around still since they dont cost much, just trying to determine if i'm feeling that ambeitious to swap it out some afternoon...i know it'd make a world of difference, but i'm just trying to race since at least it's consistant and make the car earn some money back...spent most of last season wrenching with all the troubles i had so this thing owes me...i'm not happy at all, actually everytime i get a timeslip i get mad since it's so focking slow from where it should be, but it is what it is...just trying to enjoy driving instead of wrenching for a change....and bracket racing is'nt all about speed anyhow, even though going slow sucks ballz.

the one guy thinks if i strap the front end down, turn the 2 step up to hit the tires hard it'll pick up .2 at least since it's not wasting all the power going up, and i agree, but i also wonder about traction since i'm worried it'd throw the current set up into disarray...wont know until i try it. same with mufflers, i think this bigger sbc is moving more air than my past ones so it's possible taking them off may get me a .1-.2 increase, but open header is cheating and gay IMO, i dont like having my brain rattled everytime i fire up the car...but someday i make drop the exhaust and make a pass just to see...but my whole goal has been a docile pump gas, muffled 10.5 second street car. I'm almost there but got screwed by the guy that hogged on my heads and recommended a comp cam still cant believe i allowed that to happen, but i figured i'd give it a shot....and just like trying M/T...i was disappointed.

i know that feeling.. a couple years back, when i first got my mighty demon, it was jetted completely wrong.. the car should have been in the 11's but i was running 13.1-12.9.. after 4 runs, i stopped for the day.. came back the next month with a new tune and was still going 12.4-12.5.. then an electric water pump, gear swap and tire swap(DR's to QTP's) got me my magic number.. 11.8 right off the street through open header.. still not satisfied, did a little more tuning, hurt the motor in the process and still got to the 11.65 i'm at now.. with all the $$$ i've spent, i should be at least around 11.2.. the damn car wont even 60ft for its life.. i've recorded one 1.65 and one 1.69, the rest were 1.71 and worse..

well nice picture.. and dont forget a picture if you try for that bumper drag..

Re: Nice launch picture

What tire size and pressure? It's amazing what can happen with good track prep also.

As for tire pressure, slicks, radials, street tires etc are all the same. Start slightly low then keep increasing tire pressures until 60' times start to drop off. You want as much tire pressure as possible before it loses traction.

Didn't take you long to make that your sig picture

I hope to hang my wheels past the 60' mark this year. Kinda screws up your 60' time when you break the beams with the rear tires though.

Re: Nice launch picture

I've never been able to go over 10psi since i would go red. Once i put that big anti roll bar out back, i lost all tuning for R/T's since it popped the front end up and out of the beams, 10psi is where i needed it...not for best performance, but consistancey on my lights to stay green-i'm a no box guy remember So that's another reason i've never really looked into goin waay the other way with air, i assumed it'd make my reds redder..but suprisingly, they're not, must be the car lifting instead of going and knocking some off. This pass was a .024, run before with 10psi I was .027, not what i expected at all.

Prep was the same, when i first unloaded my car ran the exact dial it had on the window from the last track back here at home, all my incrementals were the same, all my segmented times were the same, everything like back home so i did'nt have to change anything and traction was'nt any better/worse than we're used to here.

Re: Nice launch picture

Alright, buddy got my picture from Friday's qualifying uploaded. so here is Friday, racing at 10psi like i have for years and years, look at the tire/s and see how much distortion on the tread area there is, how much deflection in the sidewalls there is...no wonder the sidewalls were shot by month's end. then the second photo is the picture from above at 15psi on saturday, it gives a day and night look at what just 5psi did for me and why i'm going to see how much more i can put in them.

friday-10psi

Saturday-15psi

IMO the two biggest myths out there are low tire pressure and big long smoky burn-outs are the secrets to traction.

Re: Nice launch picture

I have rarely seen slicks that have to have extensive burnouts to hook, but they are out there. They are usually old i think.

I could'nt agree more, with a true slick/soft compound tire, like most people say, if you see smoke, you did too big of a burnout. the medium compound like the Hoosier QTP's i used to run had a medium compound and i tried doing just the tire clean like i try with my slicks and it just did'nt work, those tires wanted a good smokie, but like these slicks i have now a simple 2 second burnout and roll out of the box is sufficiant, all the new tire compounds get tackey very quickly, and often a big burnout like ya already know, will actually make the traction worse since the tire gets gooey.

A year or so ago J. Force botched the burnout and didn't even spin the tires. He staged, hooked, ran a 4.8 and won.

Sometime in the same timeframe, T. Pedregon did a little Q & A column in National DRAGSTER for his sponsor and the question was about burnouts - his response was with street tires, you need to heat them up really well (runs counter to what you hear around here), but slicks don't need it. He went on to say the purpose of those big burnouts by the big boys was to get heat into the drivetrain (what he didn't say was to also please the crowd).

Both BFG and Hoosier told me not to do big burnouts - just turn them enough to clean them off. "The traction is in the compound," they both said.

(By the way, nice launch picture. . . )

Re: Nice launch picture

Fuel cars don't do the burnout to heat the tires. They do it to put heat in the engine and drivetrain. Tire compounds have come a long way. They do need some heat but nothing like the old tires needed. The old Firestone slicks needed a lot of heat. 1960's type burnouts for an 8" slick.

That's some real nasty sidewall distortion at 10 psi.

Re: Nice launch picture

i know my car doesn't have the power that yours does josh, but i'm running the same tire (29x9) at 18psi with good luck. if you look in my sig, you can see it's not distorting really badly, but still obviously hooking.

the car looks great too brother! i can't wait till mine does that one day

M/T full slick 29.5x9 and i used tubes since they were so soft they could'nt even hold themselves up when i took all the tape and packaging off of them, they just collapsed on themselves, plus all the guys i know running M/T have issues with air leeching through the sidewalls.

I may try doing a clean out and go once, i did that at a track down south once, cant remember what happened, had a brain fart of some sort and more less got a turn or two on the rear tire and that was it...i remember i was mad and threw away a time run since this track was new to me...oh no, it was the best 60' of the weekend, i did'nt change my routine since, well, as you racers know, it's hard to change routines since it messes up everything you've autopiloted to date, but i may give it a shot again once i get my rebuilt carb dialed back in.

Shoulda'nt be a problem, the car's never really had issues hooking up, their track prep was nothing to write home about, just as good as any other...upto that point all my incrementals were the same, my home track has phenominal prep so i have no fear at home having traction....i may tow down south and race saturday since it's supposed to be nice...if there's a track in Iowa that has iffy traction at best it's the one i may head to....all the other's are very good.

It's a junk azzed Comp Cam...wanna buy it???Once again proving Comp's junk has to be extra large and under deliver in performance.

262/266 @ .050
.666/.626 int/exh with 1.5 rockers
106LSA

the Buller cam i had before that was running 10.60's with wrong convertor's was smaller all the way around and alot more streetable....so once again reconfirming why i think Comp is yet another big corp that over advertises under delivers when compared to what else is available...but after last season's money spending spree, it's getting run as is even thoug this thing wont fall out of a tree...but it made more power on the dyno with the butchered heads and junk comp in it

Re: Nice launch picture

nice pics, you got the guy with the camera to get a good spot lol
I cant get the guy with the camera out of the covered grandstands so i wind up with side shots like this

but a friend got this when i ran at atlanta dragway for pinks all out, this track was junk, huge bald patches of shiny concrete right about where the rear tires are in that pic

I really need to talk the guy with the camera to move to a diffrent place lol

the Buller cam i had before that was running 10.60's with wrong convertor's was smaller all the way around and alot more streetable....so once again reconfirming why i think Comp is yet another big corp that over advertises under delivers when compared to what else is available...but after last season's money spending spree, it's getting run as is even thoug this thing wont fall out of a tree...but it made more power on the dyno with the butchered heads and junk comp in it
honestly i think its just too big. i dont see why that car wouldnt run 10.60's with something more in the 240's duration. just going by my gut. especially your car being as heavy as it is.

It's more of a combination issue, the old Bullet i had with the first version of this engine with out of the box heads...before jackazz hacked them up, was similar in duration, but lift was only .626/.626 if i recall-it was'nt bigger than that-and the LSC was on a 108 instead of the current 106. I know what dumb dumb want gum gum at the machine shop was thinking when he speced this on a 106, but with the rest of the combo it just is'nt the hot ticket...and i was running 10.60's with the smaller cam and wrong covnvertor...it flashed and held at 7000rpm the entire length of the track, but i never got a chance to try it with the proper convertor before the crank snout snapped off that one and dumb dumb told me he could get me more power.

I really want to call Bullet and get another cam coming, but i also just want to race, and we all know bracket racing is'nt speed sensitive so for now i think i'm just going to stick with my junk running like crap. the right cam would help, but it still does'nt fix the fact this shop ruined the heads. When we were at the world street challenge last weekend i ALMOST bought a set of AFR's since i was intending to put them on this engine, send these heads down to Kansas to get fixed/made right and then build a back up mill...but i did'nt.
----------
Took it to the crap track down south today and the 4.11 i put back in tamed it down alot, same 60's 1.465-1.469 for 3 passes and then the hour lunch down time, 4th pair out and i got to see the spectator stands when i let go of the button...kinda why i steer clear of this track since it's a POS to put it mildly...when you have the locals telling you to dial .1 soft after lunch break it speaks volumes. they do all your time runs before lunch, then shut the track down for an hour, and then call you up with no prep done to the track at all...just a cold track after sitting for an hour But dropping gear did what i wanted even wiith a 15-20mph head wind straight down the track.

Same ET as last weekend with the 4.56, Same 60's, we dropped trap rpm by 700 (was at 73-7400 and now we're down to 6600) and we picked up mph so i was pleased all the way around...the thing is still slow as heck, but it is what it is at this point/this season.

Re: Nice launch picture

I say leave the cam you have in it and put some AFR 227 eliminators on it. I bet you pick up a ton of ET. F up heads = bad performance the cam sounds close to me you have seen my cam specs and it is a comp cam it runs well. The 106 lobe sep on the 4'' stroke is the only thing I do not like on the CC cam but it works for others.

Originally i had 100% intention of buying the AFR 227's but i already had these pistons and the 227's need a 60/40 valve space piston. I called JE to see if these slugs could take the fly cutting to make them work and the guy told me, "well, there might be enough material there to do it, but the bottom line is that is a half azzed way of doing things, you should just order the correct pistons if you want to run heads with different valve spacing" I was'nt about to buy an additional set of slugs when there came with the engine and had less than 40 passes on them, so i opted for these brodix 227 100% cnc'd heads instead...which were fine out of the box, but then dumb dumb started hacking on them, supposedly he picked up low lift and overall flow numbers but ruined the flow/velocity of the heads.

I may just get some new heads this summer, new cam and store it until this winter and pull this, have it freshened and build it back to what i originally had, then get this stuff fixed and put my old 388 back together since that was a nice running docile driver/racing engine.

Re: Nice launch picture

if you have the pistons out and in your hand you can mesure the thickness of the pistons on top to see if there is enough , i know it not apart though so its a moot point. I have srp pistons and had to fly cut them due to well lets say an interference fit with the valve, the guy that did them said naturally aspirated you will never have a problem with the .180 thickness i just cant say what nitrous will do, so far it holds a 225 shot lol. moral of the story yeah the guy who sells pistons is going to want to sell pistons, finding a competent shop to fly cut in the first place is hard enough, finding one that has knowledge of how thin is too thin is another story, the guy that did mine even made the cutter with a radius so there was less cleanup work after, and even told me over the phone how to mark them so he knew where the center was, i want to say he charged 125 for reference and had them done in 1 day!

Re: Nice launch picture

Yeah, the charge to have them fly cut is minimal in the big picture. JE said there is probably enough material there depending on how large the cam lift was and duration of it was, but "as a racer i would'nt recommend it, it's just a half azzed way of doing it and setting yourself up for possible future problems" so that's what i took away from it, trying to stay away from future problems. I know plenty of guys that had their pistons fly cut to clear larger valves with no issues, but i figured after looking at flow sheets these standard spaced 100% cnc'd brodix heads flowed darn near what the afr's did, cost the same but i did'nt have to mess with cutting slugs, so it seemed like a win win. and it was first time out with original engine before that crank snapped and put me back to square one again.

I need to get away from this small block stuff and just go BBC, make alot more power for alot less money and alot less wear and tear to boot.

Re: Nice launch picture

I guess all engines have their problems, compiled with people that supposedly know what they are doing screw things up on you, hey erica enders is selling a few pro stock engines, might be cheaper than what you have spent on that unfortunate mess

Re: Nice launch picture

josh, left rear looks a little distorted still, maybe try another .5 or 1 pound of pressure and see what happens. Look at the lower portion of the tire in that launch picture, looks like the tread is still wadding up.

I need to go down in psi if i look at the tire tread, the outside edges aree still feathered like they were from earlier in the season, but i have a nice 6" wide strip in the middle that's good and clean, like a new tire. i aint touchin nothing...it's working like a champ and getting me money everytime i enter a race

Hey IHI when are you coming down to eddyville again? Are you coming over for the 4th of July Weekend? I hear you about going away from the small block, but i might go with a large by huge LSX instead because i'm trying to keep weight down

Do you know what they're paying out that weekend? i need to get my R/T problem fixed first and foremost, and keeping in tune with every other racer, that purse had better be large to justify the trip, I'll race for $1K but nothing less, and even that is iffy since round money usually sucks. Hard to go anyplace else when the home track pays $2K Saturday/Sunday and it's only 15 minutes from the house...so to answer your question, i dunno LOL!!

We're heading to Worlds of Fun at the end of june to visit relatives and take the kids to the park, and with all this dam rain this year, i have'nt pulled in a decent check yet...working in 1-3 day spurts/wk if i'm lucky is how it's been all season thus far...so pennies are tight right now. Told the wife I'm gonna hate to be the company shutting the doors since i cant make it through until it dries up LOL!! we've got about 2 months of work lined up and still bidding like mad, but if i cant do it, i cant make no monies, and to be honest racing is somewhat helping me sustain right now even if it's not winning the whole show, it's enough to profit $100-400 after everything for the race weekend is paid for.

Re: Nice launch picture

what suspension are you running in the red firebird. im building a turbo camaro and im debating between tq arm and ladder bar for a 10.5 tire or something similar.
it will be a street strip car.
im more worried about down the track traction.

Re: Nice launch picture

I'm not sure what the payout is. I also live 10-15 minutes from my home track which is AWESOME. whenever i can get my car done i might start doing some of the box/no box races try to help pay for some of the new improvements

Front-
moroso BBC trick springs
lakewood 90/10 struts
remaining all factory

Rear-
stock springs
lakewood 50/50 shocks
tubular LCA's
stock panhard
wolfe craft anti roll bar-a must IMO after having it and looking back at before
Jegster adjustable tq arm- puts alot of anti squat in the chasis so i dont know if i'd be too worried about down track traction since it drives the tires into the pavement pretty good.

The weather this year..along with gas prices is really taking a toll on everybody that has to make money with anything done outside. i know car count this yr is dismal, but when most of our racers have to tow 2-5hrs to get here, $4/gas,diesel, and most weekends they call for 30-80% chance of rain each day or at least 1 day so most guys stay home and i dont blame them a bit. We had one big day a few weekends ago, went 7 rounds to the last 3 cars but it was a bye back so no points, and then it's been crap count ever since so i got my work cut out to get back up there LOL!! not that i caare about points sincei cant buy gas with a point, but a lil sumthin at the end of the year is'nt all bad either.
