Wow, gone for a day or two and I have all this catching up to do....all I kept thinking while reading this was "So what, my dad can whip your dad!" A couple thoughts... - flow benches - Although they are great for any honest street motor(meaning a truely street motor), they are no the end-all. While this is an apples to oranges comparison, pro-stockers use the benches to a point, then they go by knowledge and trial/error. They have proven that the air-speed in most pro stock cylinder heads approaches/surpasses super-sonic, thus a flow bench can't truely measure them with real accuracy. - By no means does that really relate to most real-world engines, but it is just to note that racing flowbenches is just like racing dynos. The guy with the biggest/best numbers doesn't always win. - I have no qualms with doing mild port work on heads and intakes. Smooth the bowls from stock casting flash/seat edge material, put a smoother ark in the radiuses and roll the runners out to smooth entry from the intake. I don't f* with the intake port runner(other than a paper wheel), and I only open the throat/guide area on the exhaust of under-performing heads like vortecs. - Wet flow benches are considerably more accurate, but also considerably more costly, less widely used, and fairly new technology. - My vert was retardedly heavy, but that was with full GTA options, the convertible top and associated sub structure, through floor frame rails, an 8 point and harnesses, dual 2.5 exhaust, clutch can and 168 tooth steel flywheel, and a competition sound system(my HCCA 12's weighed over 40lbs each, w/o the boxes which were 1" mdf, dual batteries, dual alternators, capacitors, and amps). Many of you have probably read this from me before, but 4001#'s w/o me in it. I wonder why I broke so many T5's.... One way or the other, that's a retarded weight. Not only from a performance stand point, but from a safety stand point as well(weight multiplies momentum in the event of an accident). ......so I'm still thinking my dad can whip your dad.......

Read my dad's JCB backhoe i posted a ways back, if he cant beat ya, he'll crush ya..either way, he wins My dad in his backhoe makes chuck norris look like pee wee herman. man dad in his back hoe make vin diesel looks like he does'nt know a thing about nozzzzz.

this guys thread really went 2 sh!t
IB4L

The thread was not asking questions, just giving heads up on how he performed and expected results here in the near future, so after the koodo's it just turned into a typical drag racing thread full of all ideas, thoughts, opinions, etc...

Thank you. I would NEVER do any work on aftermarket heads though besides cleaning some flash, or like i said,some junk *** pro comp heads.

Before you jump the gun too much there's something you should know about me; I went as far as mid-level calculus in college and took some advanced physics classes where we studied air-flow characteristics. - Between the parting, lack of motivation, and lack of $, I didn't graduate, but I have a decent bit of knowledge on port work.

I still only do my own **** or very close friends, and still only do "touch-up" work. I've gone further, but not without input from a close friend who does cylinder head work for a living.

its naawwss man, get it right!

Chuck Norris should have put a patent on his name. That way any time it's used on the net he gets a penny or something; by now, the US would be asking him for a bail-out loan.

Damn it, i am clueless

I was laughing my azz off the other night the original F&F was one, scene where they first really met and were in the car together and the chinese dudes came back and shot it up, diesel looks at surfer boy as the car is burning and then yells NAAAWWWSSSS, as they both turn to run she implodes into a pretty blue fireball

^ the best part was, they really didn't loose anything......wait, maybe he had some nice sunglasses in the glove box or something?

Same here.

i also am guilty of "porting" ls heads, but my car down put 490 with a 375ci ls, so i guess it was not all that bad

****, if i picked up 40 or more cfm on a rush job, i guess i am not horrible at it.

you can get all the cfm in the world out of a set of heads and if they don't have the proper velocity the motor will make less power. That's why I pay a lot of money to have a complete competition port job on a cnc machine that makes repeatable results time after time. Besides the heads that I typically buy don't need a bowl cleanup or something simple so I leave them alone.

EXACTLY, but i dont think he understands that, in fact i'm sure he does'nt. My heads for example made ALOT more power straight out of the box, then a dumbazz thought he could massage them a bit and gain some more out of them...well, he had the ports identical, he had these 23* sbc heads flowing 335cfm @ .700, and i was .5 slower on the race track and 4mph slower, convertor flashed 1800rpm lower than it previously did...but boy oh boy, he had them moving some air

fast forward this winter, sent them in to a reputable shop to see what they could do with the heads, if they were even salvagable or just future door stops, luckily he was able to repair them, and like the guy told me, you wont have near as much flow, but they will have much better velocity. True to form, we're lost overall cfm, went from a lazy headed 335cfm to a very good 328cfm and the dyno results from a few weeks ago spoke for themself.

When i chose heads, i look at flow numbers, but in all reality i'd rahter have a lower flowing head with excellent velocity vs a big flowing lazy head, sadly most guys dont know anything about that and ole Zones seems to be one of them

wow, not a huge drop in numbers but i bet the velocity went up alot. Velocity is a nice component to have but too much also is bad. AFR loves to advertise port velocity with there high flow numbers for a small port size, and it does help make power. Just gotta be careful you dont go overboard with flow speeds

over-board with flow speeds? eh...explain justin...i didn't know that was possible...i haven't said anything the last page or two cause we're getting into a realm of understanding i just haven't quite gotten to yet. another few calc classes and some physics classes and i'm hoping to be right there with you guys, but currently, i'm still in pre-cal and trying to teach myself the stuff ya'll are talking about by just reading everything i can get my hands on on ls1tech and here...

Well, that is it. You once again proved you are not paying attention.

Read AGAIN: I ill not port on aftermarket heads. I would not chance doing any damage. I will do the minor work on stock heads. But that is it.

But whatever, keep on making up anything that makes you feel better.

So you started the thread being this great know it all on engine combinations, head and intake porting, and have now changed your tune to become somebody that is very selective in the heads you port...nice. if your going to be a chit talking tool, at least pick a side and stay true, your name is mud either way, but if you can be a consistant liar/hack at least you'd have something going for you instead of jumping all over the place with your wanna be wisdom for each particular rebuttal when you get called out.

I never made claims but mentioned i have ported and what not, so whatever almighty asshat.

this dude is too funny. i thought he was some 16 year old chiming in, but turns out he's 26????? hmm....i doubt that.

hey dude, he is entitled to his opinion, just everyone else here.
no need to pour more gas on the fire.
dont post just to bash him

Oh yea, i have more post than you

when did he say he was 26? - not that it matters, I just must have missed it.

He looked at my profile shag.

- ignorance is bliss. I don't think about that stuff.

so you have more post...that makes you smarter or more knowledgeable?????? well i've been a member longer that you! what does that mean? NOTHING. and yes back to subject. these cars are sick, and fast. yet you talk smack. i'm not talking smack, i haven't ran my car yet. and from the sounds of it, you haven't either. so i would ask question, or give constructive critique or shut up.

It was a joke...

and no...you havent.



We have pretty much squashed this and you are trying to bring it up....stop.

LMFAO!!!!!!! its only slower on the bottle than it SHOULD BE ON MOTOR!!!!! ....After how many merry-go-rounds?


Sorry I dont agree with either side for the most part...ur all a being ignorant right now...but that was funny!...and TRUE!

Once again, we have dropped our differences and someone is still bringing it up.

That's why the laughing gas got installed last year, i knew the guy ruined my heads and engine was a POS, hence why i was hot after this jackazz was proclaiming to be porting on peoples heads with no way of being able to track progress. Now the engine is making some power like it shoulda been years ago, only took getting screwed over by two machine shop before finally taking matters into my own hands to figure out how terrible they really were.

Not saying my junk is fast, plenty faster and always will be but fact of the matter a 3768lb slug that runs on pump gas and now that i got the correct convertor installed yesterday for the new 640hp/600tq sb engine should be a 10.30-.40 car pretty easily and well into the 9's on the spray, already ran a 10.59 @127 with the old convertor going directly to 6500 when i release the transbrake and 18.7% convertor slippage in crap air. When i really want to go fast fast, i'll build a pig block, when i really want to go fast fast, i'll get away from pump gas and docile street driven internal parts combo's, but until then i want a reliable engine that's easy on parts, does'nt get hot, and gets me down the track and makes me money. Make no mistake, building a bracket racing combo is 180* different than building something to go fast when consistencey does'nt matter, just a time slip to brag about. I know plenty of guys that get that one time slip and that's the last time they ever see that time, while i'm forced to zerox time slips round after round after round...if i were building/tuning for all out each pass, that would'nt happen

ran my car at the track yesterday josh...i got a LONG way to go on tuning it. oh well.

Oh buddy, i know where your coming from and dont envy you a bit, one of the reasons i have no serious interest in any forced induction stuff....just a lil too much money to sort it out and frankly, there are no shops around here that have a definate answer about dealing with it so i'm stuck N/A with a lil spray.

Good luck, just remember...mo money, mo money..throw enough of it at a problem and it will eventually go away, there will be new problems that pop up after inital one is solved, but mo money is ALWAYS the answer...ALWAYS

oh no it's N/A ls based motor in there now. lucky #9

The twin turbo stuff leaked some oil out of the turbo seals into the downpipes and a guy bought it all off me for a good deal IMO so I tossed in a 55k ls1. No one local or online runs a carb'd ls1 and can tell me their timing curves so I can start out. So I just put in 28 degrees into the laptop msd software and let it eat. Traction wasn't that great at the track rental so I spun every time out of the hole and sometimes down the track as well. Couldn't shift above 6k either or it would want to move out on me.

what kind of tire were you on?

28x12.50 ET street, set the pressure at 14psi cold and once at 13psi with no luck, didn't have time to make many runs so it is what it is. Just happy to make passes for the first time in 2 years, these slicks are from last season and got better with each pass, probably getting to fresher rubber in them after the burnouts would be my guess.

Mickey Thompson's sucks they did'nt prep the track, but the weather just flat out sucked last weekend and was far from ideal unless it was an actual race race with a bunch of good tired cars running to retain track heat...just too cold and windy to stay stickey.

What about taking your reserch down a different path, call and talk with MSD since they designed the components or even Edelbrock and get with theri tech line and have them transfer you to somebody involved with the R&D side that will have actual dyno information of what they experienced/found through development of this stand alone set up to get rid of the EFI garbage. I know before i decided to try E85 i spoke directly with Quick Fuel, APD, AED, Ohio Crankshaft picking their brains as much as i could since a few of those companies were working together/testing to find the right formula to make best use of the corn fuel. Really cleared up alot and once again shut down most of the internet BS that's littered cyberspace with theories that get misinterpreted by some as reality

Might be a situation where setting up on a chasis dyno could save you a lot of gas in track passes and you will be able to see exactly what you need to do where to optimize quickly...just dont come back with some chasis dyno numbers, throw them in the garbage since unless your convertor locks up 100%, they wont mean a daamn thing anyways LOL!!! Local forum has two guys bragging up 712rwhp at only 15psi boost....and once again goes out and run's 11's, and yet, i'm the idiot and does'nt know anything, dyno numbers are TRUE, it's mathmatically impossible to not be right. LMFAO!!!

well ls1tech has a few carb combos but those guys are all about "good enough" numbers and just keep them at 28 degrees like efi and stop tuning. MSD had no info at all, edelbrock licensed their boxes and put 36 degrees of timing in them, which everyone and their brother online states is "too much timing" and the curves are really really jacked up. I think it's more a set it and forget it thing with these guys. With all the wind I was all over the track, my first pass on the 2-3 shift I got kicked out of the groove and had to lift a few times

wow TJ, this is like the thread derailment of the year dude!! It's the first time I've been here in a week or so....holy sheeit!! How'd it go in Mobile Saturday night?

ARRRRRGGGHHH! this thread has been jacked, you're far too late.

it's all the same in these threads :P I dont know what you're talking about.
