Pretty stock now, looking for more power, but I enjoy the stealth factor. Was thinking slightly bigger cam, but not much, I don't want a real detectable lope. I was also thinking of adding a good set of heads for more flow too. With heads and a cam, I know everyone will tell me I need headers but I hate all the added sound of headers. I have a Corsa now and I like the sound just as it is. I go to the track and see guys running long tubes and I don't know how they can stand it. I want to keep it quiet and stealthy and stock sounding as possible.

Please give your input on cam, heads, & exhaust setups.

Thanks.

 

C'mon, if this question has been asked before, someone at least throw a link. I tried searching but the answers come back differently as the technology changes. I'm looking for something tried & true!

 

Mods and numbers in sig.

Cam doesn't sound too *obvious* at idle, but you know something's up.

Now at WOT through that GMMG, there is no doubt.

But it's what I like

 

Without a doubt, you're gonna need a good exhaust for added peformance, which includes LT's. If you don't want it to be loud, go with some Magnaflow mufflers. They're very quiet for that stealth you're looking for. As for a cam, 224 is a mild cam that makes decent power and doesn't have much of a lope.
And besides that, you really should look into getting like an Ls6 intake/tb.

 

I dont know. I get compliments on my car all the time and I have the original SLP d/d still. The idle is detectable. It isnt an old school thump but its not close to stock either. I've had people hear my car at idle for 1 minute and know somethings up with it. A tr224 is pro'lly the best street cam but a sleeper it is not. Even with factory manifolds your gonna hear it. Dont be frightened by other people who have LT's and are loud. They're loud because they want to be. A catted Y and a semi quiet catback is all you need. I'm putting down 440-450hp and 420tq with a mild 224 cam and TSP heads

 

Really? I would definitely get a catted Y-pipe since I live in a state with emissions inspection, but that and a semi quiet catback will calm the headers down, as far as noise? I'm skeptical.

 

Get a mild cam...like sais before a 224 is good. You will need some LT to take advantge of that power. Get a y-pipe and install cats in it. It wont be that loud, but it will sound really good. Or just leave it all alone and install a single front mount turbo setup...that can be pretty stealth. I can help out with it all if needed.

 

Honestly. My car is loud at WOT but not raspy and blathering. It is nice and subdued until that. You need to look closely at the cars that your talking about that are to loud with headers. FInd out what their exact setup is. My guess is you've heard them with ORY's and a Borla or GMMG or some other intended to be loud exaust. The header add quality to the sound of your exaust. The Cat back you choose makes the difference in loudness.

 

The guy who is buying my old cam is buying it because his 224 did not lope much at all... I listened to it myself, and very much agree, threre was very very little lope in that cam.

 

Which 224 cam is it? I guess there are a few out there now. I have the TR224 on a 112 lsa. Dont get me wrong I highly recommend the TR224 all the time.

 

Lope is not necessarily a product of "large cam". Amount of lope has to do with VT, with the amount of overlap in valve events, if I'm not mistaken.

You could have a cam with fast ramps and high lift and still have a seemingly stock idle. For example the CheatR cam. It's on LSK lobes IIRC, it has over 0.600" lift but has a shortish duration. The result is a cam that makes a lot of power and has great drivability and stocklike idle.

But with that cam IMO you need some strong springs to safely control the valves.

 

It's the same one you have. Maybe there are other factors that affect the lope. I dunno... It does make pretty good power though.

 

Lope is in valve events and duration. LSA really doesnt matter much. its just a by product of the valve events.

 

I suppose what I SHOULD have said is maybe there are other factors that affect how much you HEAR the lope, not affect how much lope there actually is.

 

I'm not saying its a real pronouncable lope, its a subtle lope. If someone didnt know what a lope was they might not recognize it at all I guess.
I could take a clip of it and post it somehow.

 

You can use photobucket to put a vid up. I just figured that out this morning.

 

we did a Cheater cam/Afr 205 (outta the box) and a fast90/90 and Lt's....put down 437/421 (after a tune) i believe if i remember correctly. sounded near stock too.

 

Thats nice, thats real nice

 

hell yeah it is....

that should be the text book response on how to make any LS1 break the 400/400 mark....

 

Another important item to add is that I still have the stock 3.42 rear end and don't want to change that if I don't have to. That adds to my desire to have a heads/cam setup that doesn't sacrifice low end. Just the opposite, if I could GAIN some low end, I'd be pleased.
