boost questions for boost experts...

The effect of high octane is that it slows the flame propogation and cools the combustion event. That is the reason that low compression cars slow with too high an octane in the tank, and high compression, boosted and/or juiced cars speed up... because they can apply more of the same with no fear of detonation. They do so because octane controls the burn much more effectively. That is the end of the factual discussion.
PS-
While I know that my statements regarding MY OPINION of PUREVL and Brian W may instigate, I want them to know that I respect them because they are two of the few that are trying to advance the LS1 sport. Please don't take it personally that I don't share most of your views, I still respect the effort. Thanks!

. I have gone 127 at 11.5 with street tires with the d1? Does that help? As for me being a punk running my mouth, you should really really find out who I am, theres plenty on here that know me. PM me anytime you would like to meet me when your around. I would LOVE to meet you.

As for meeting me, you are better off behind your keyboard. I am way more experienced than you'll be able to handle. That's a fact. I know that because "there are more with us, than there are with" you! Figure that out sonny.
I baited you and I knew you would react even though I said I respected what you were trying to do, because you're a "just barely post-teen" thug punk. It's what you come off as. You never saw the props, you just got caught in the OPINION. Why? Because you're a teen aged punk, and that's all you are. Grow up!

I think maybe a mod should step in on this one and put some water on this fire that might start. I realy dont see a need for this thread to take a turn. The information was good up until this point.

Not sure why that song popped into my head while reading this last page but I found it fitting.
Bryan, to get back on topic with this thread. Do you feel that he could run 16psi on pump gas and make great power or would he be better off running lower psi with more timing etc? This is if he is doing nothing fancy with the 6.0L heads and using the stock cam.

The stock cam will be the restriction with timing. If he ups the cam specs and changes a few things, then he can get away with more timing and changing the events in the chamber. But if its stock, the best bet is more boost less timing.

yes...the whole point of me slapping these 6.0L heads on the 5.3 block is because its gonna be cheap as hell...dirt cheap..next to nothing. if i can avoid it id rather not buy high flowing heads for more than i payed for my engine...a cam is a good possibility though, at least with more duration and lift than the stock truck cam. the exhaust isnt going to be very free flowing either, it will be manifolds upside down and backwards which i dont think matters much before the turbo anyways because the turbo is a huge restriction. also i will have shitty stock twin grand national intercoolers and grand national turbos, the intercoolers will be in direct airflow though. im on a mission to make the cheapest twin turboed gen III SBC ever. what are my best options?

Well there is the right way and the wrong way.....I choose not to do anything halfassed.
This is the most irritating thing you said, and it is getting old everytime I hear it. You cannot apply supra, viper, hemi or any other logic to LS1's it is not the same, and until you have proved me wrong with a LS1, or LT1 of your own, take your story somewhere else.
And I am still curious as to what email did you read where I stated that I had a flat pistons.
Unfortunately if you want to drive it on the street and get good gas mileage, and have good drivablity and then take it to the track on Saturday, you have to follow some basic engine building rules.
Supra's are nothing more than wanna be's, take your story to a tuner forum. We are not interested.

The 1st one is going to be more reliable. Where in the world did you get the idea that efficiency didnt make power. That is engine building 101.
All I am saying is in order to increase volumetric flow (is this what you mean be effeciency?) you often make trade-offs in drivability (unless you can increase displacement). Example: Driver A wants a stock idle, while driver B doesn't mind some lope and surge. Both want 600whp, and neither can afford a larger displacement motor. Driver A needs a smaller cam and more boost to achieve that goal.
Of course if you want maximum power, you would increase the engine's natural airflow and boost at the same time.
I don't disagree with your comments about folks fixating on 'boost' but I do disagree with your advocacy of pushing high hp combos with just pump gas and nothing else. Until you make a few high mph blasts and the block lives, how can you say that 822rwhp was safe on 93 pump gas?

Why?
Because you, and others, have posted more bullshit than can be safely waded through.
As for ceramic coatings, you can start a new thread about it and copy/paste my old posts into it and get owned all over again.

here is my situation
im looking to make the best power i can with stock parts mostly, because they happen to be the cheapest. i dont need 800-1000 rwhp, ill be happy with ~500 rwhp. this engine (5.3L LM7) will end up in a 2700 lb rx7 whether i turbo it or not, and should be fun either way. i was thinking about an LT1 at first because it was a little more in my price range than an LS1, but these truck engines can be had for around the same price and fwhp, with better technology and most if not all of the LS1 performance upgrades available. not to mention being able to drop the compression with cheap heads if you want.
the whole idea of me using stock heads, turbos and intercoolers from a 6.0L truck, and a grand national respectively, was to build a cost effective, powerful FI motor whether efficient or not. probably the most i would do in the way of opening up flow to the cylinders would be some home porting/polishing on the heads and throttle body and a cam.
maybe we could bring the thread back on subject talking about the best course of action with this setup would be for 500 rwhp
(like what i should do about cams)

Vortec7,
You can achieve you goal with the stuff you have stated NP. I did it in my truck using much the same combo except I had a rear mount turbo. If you can get the tune safe which it sounds like you are on the right track then no reason you can't make 500rwhp on such a small drivetrain.
I had a cam and meth injection but I am using so little meth right now it's not making a huge difference.

edit: almost forgot you had a rear mounted turbo, throttle response probably wont be the same...also, what did you calculate that your static CR was after the 6.0 heads?

I had Rick at Synergy tune it using HP Tuners I believe. The new setup will use the Speed Density progaming from HPT.
The 6.0L head dropped my CR to about 8.6-8.7 from my calculations using stock gaskets. Using Cometics I believe it might be between 8.5-8.6. Not sure about quench, I don't know much about that stuff.
I had an oversized turbo and it was in the rear so my throttle response was ok at times and at others it was kinda poor. Like just driving around town it was great and I had to be carefulk how much throttle to give because I would start seeing boost and it climbs fast once it starts. Now getting onto a freeway was a PITA! I would give it the normal amount of gas you would while entering an onramp but it would sit at 5psi and feel like I was towing a 10lb trailer. The power was fine but it would seem like it was making alot of noise to go nowhere. It pretty much only did that on onramp situtations though. Normal driving was fine or if I left the boost gauge on high so I could see more boost (at part throttle) then it would get quite fun quick fast. 
On my new motor we are going to bump it back up to about 9:1 for a lil better streetability. Since we are building a whole new motor we can pick the CR easy. On a stock motor that you don't want to tear into the 6.0L heads are a good way to go BUT the 5.3L is only 9.5:1 CR stock so you might wanna try that out and see how that works for ya if streetability is a major concern and you're only looking to make 500rwhp.

Track time is useless information for the topic of this conversation. We also need your compression Ratio for the conversation also.
