is this possible?

[jonszr1]

I am sorry son you are JUST so full of yourself . I'll bet you get chapped lipps kissing your self. why can't you just do the right thing and post your dyno sheets. whats wrong with being a stand up guy. ? is that too much for you. Or just show up with your so called stk ride at the next west gathering in vegas and I will race you for what ever ya want to put up money is no object to me . I was just trying to help ypou in asking to post your dyno sheets .I had non believers when corey did my car and out of respect posted my results for all to see. Anyone can come on here and posts anything but the true measure of a man is his honesty and producing the info to back up his words. So which are you a good guy or just another POS that likes to upset good decent people/ let me know when you decide .!!!!!!!!!!!!!!!!!!!!!!!

In my opinion it's best to achieve the 500+ hp in a regular C4. It's cheaper, and easier to work on, and when it's time to sell, it's easier to sell a modded regular C4 over a ZR-1".

I posted on another forum i belong to. dometicmisfits.net
the above mentioned quote..was from a guy we call numbers guy,
he seems very knowlegable about cars...and owns quite a few it seems..but...when i posted the question to the forum there..about some upcoming mods..i have been thinking about...he anwsered with the above quote...my question is

Is this possible?? with just bolt on's? cause i have headers...and corsa exhaust..and i only have 353 rwhp...before the corsa.
when i dyno'd in may...i was wondering...whatcha think?

When I purchased my car in April 2003 topend port work had already been done and it had SW headers/no cats going through a stock exhaust. The car dynoed 377 at the wheels with this set up. Two years ago I added a B&B exhaust and RT cats. I did not dyno the car after adding the exhaust but seat of the pants feel was that it had more power. The car is currently at EES getting upgraded to a 402.

Clearly, 8388's car possesses the most RWHP for a stock set up most of us have heard of. That said, for the vast majority of our cars the only way to get near 400 RWHP is to add a ported topend to headers and exhuast, and to get substantially over that figure you're going to have to port/polish the heads as well.

As far as the LT5 being too complicated for internal mods, I disagree. To be sure, you can't run down to the local speed shop and get the car fitted with off the shelf turbos and superchargers, but there are a few very good tuners who can put some serious bite in the beast if you choose to go that route. And even though one can certainly obtain 500 RWHP for much less on an LSX engine, those engines are simply nowhere near as exotic as the LT5 and in my opinion lack a level of "sex appeal".

holy crap...ok...sam..numbers guy...is a good dude...and i'm sorry
I even started this post...i did not intend for it to become a pissing
contest...we all know that different dyno's put out different numbers,
for the same car...if Sam, says he turned...119 mph through the 1/4 mile
that right there tells me...something is different about his car..
if he had dyno figures...i'm sure he would post them...let's all take a
deep breath..here...after all...we are brothers of the beast.....right??

thats exactly what i am trying to say he fired the first one and all I asked was a simple request then he comes back with this bs last post like a smart mouth. I am sorry but I don't back down from a smart mouth. I ain't built that way. I guess it come from my years a a ranger. But good guys bdon't post smart mouth sh*t like that. i can remember the grief I got for my numbers I backed them up . that was all I was asking until the little smart mouth posted what he did .I am outa hear .This isn't fun any more

[Pete]

I believe he could be making the power.
Cam timing is worth a bunch.
Most think inside the box,with the LT5 you have to think outside the box.

Most assume there's only 5-10hp to be had from cam timing to my suprise there is 20-30RWHP just from cam timing.

Don't critisize someone,especially when you don't know yourself.

8388 love to get my hands on your heads/intake and port them,you could probably make another 60+RWHP you would have the baddest 350ci ZR1.

[jonszr1]

n o one started by criticising just wanting to see the docs on it. I do now alittle about this motor and the effects of cam timing best i have seen . is 14 hp. but 411 with no headers andno porting =-NO way.I know he has a dyno sheet if its true so why not share. whats wrong with that ??????????

I wasn't going to respond to your childish remarks, but I think I owe it to the others reading this.
#1. I was only trying to give some advise, about the capabilities of the LT-5. You took it as if I was trying to brag about my car. And in reality, I could care less what you think.
#2. I've been saying for years that all LT-5 have the same capability, those that are willing to listen with an open mind, will eventually benefit.
#3.Those that know me, know of my car and it's power, I've got nothing to prove here. I was invited here thru an email.

What exactly is involved in doing this? I.e. where are the variables to be aware of when installing or timing the cams? And do you have any suggestions as to when it might be appropriate to try and when it might not be worth cracking the motor?

In regards to your initial statement Sam (or the one Keith initially posted from you), it does seem a little bit backwards. You are saying the engine is too complicated to get into any internal stuff, that you suggest just sticking with the exhaust mods/bolt ons and leave it at that. But you are also saying cam timing is where the power difference comes from. I would think for most of us, it is a lot less complicated and there's less risk of messing something up in removing the plenum and IH's and having work done to it, than in removing the cam covers and messing around under there.

Most of us have to take the intake off now and then anyway just for maintenance of things like plug wires or fixing vacuum leaks and whatnot. But this cam timing thing is certainly intriguing.

if you're looking to get hp/$ for mods stick to another car. This isn't the car for it the costs to port anything on this car are not a great deal. Cam timing does not require pulling anything other than the hood release as far as I know. It is easier to do it without the motor in the car but it can be done with the motor in the car from what I've heard. I'll let someone else describe how to do it, I don't have that much time right now

Miscommunication aside, this has been an intriguing and informative thread. I'm no Smokey Yunick, but I'm all for finding more hp in my beast....and since I want to pull those pieces off to pc `em someday soon (if i can keep Blue) then i might as well get `em portnpolished while I'm at it. Any gains from cam timing would be icing on the cake.
