Hey Guys, what do I need to do to make 500-550rwhp on a c5 LS1.

 

Easy way is F/I but if your trying to go N/A you can call ECS as they have a great H/C combo that makes on average the power your looking for. IMHO I would go F/I because you have a lot more room to grow. But what it all comes down to is how deep your pockets are and what you want to do with the car. Good luck!

 

i am shooting for 500 RWHP myself.
i don't have any hard facts or first hand experience but.
you need to decide if your going to go normally aspirated or not.
if you go that way you need a good free flowing intake, full exhaust headers to tail pipe, and a big cam. plus maybe some intake manifold work. that will get you there.

or you can bolt on a blower, a super or a bottle. any of these seem to get you there with enough spare potential that if you start adding the "NA mods it gets really radical fast!

most every sports car has some sort of super or turbo so why not add one to a corvette? if you keep your foot out of it you will get better mileage than NA. but what fun is that?

i am looking more and more at dropping the 5 large on a blower and calling it good.

 

I'm new at this, whats F/I and N/A, and who is ECS.

 

F/I = Forced Induction (ie. turbocharger, supercharger)

N/A = Naturally Aspirated (ie. your stock engine)

ECS = East Coast Supercharging

 

you'll have to go with a pretty aggressive cam to get 500 Rwhp. If you're looking for 500 at the crank, that's pretty easy and well within the drivability of a daily driver. this is in an NA car, of course.

 

Your not going to get there with the stock LS1 heads either, you need a heads and cams package to get there... And to make it easier, change out the intake manifold too.

You will also need a FULL exhaust. Not to mention the Heads/Cams package must be a pretty darn aggressive one.

 

what are the really aggressive heads, cam, and intake, brands out there.

 

AFR heads, G5X3 and larger cam (LG Motorsports), FAST intake or Z06 intake, good set of LT headers and a good tune. I have Lingenfelter ported heads and intake, G5X3 cam, LT headers, tuned by LGM and a 100 hp shot of nitrous and I'm at 521 rwhp.

 

Well, I've got the G5X3 cam, ported LS6 heads, underdrive pulley, and some other goodies I don't remember, kooks headers, hi-flo cats, and Corsa catback. All work done by ECS. I've got 450 rwhp. But other than the Vararam ram air intake, I've got no extra intake work done. So there might be room for some more hp there, but I don't really know much about the mechanicals, so I couldn't tell you for sure. Best bet is to call Chris or Doug at ECS and talk to them. They definitely know their stuff.

 

 

You'll need more than a cam, ported heads, headers etc. to see 500 rwhp on a na motor. You'll need a 402.

 

And lotsa money...

 

By normally aspirated, you meant Naturally aspirated, I'm sure. With what you described for your "normally aspirated" setup you wont make 500 hp. Sorry.

A blower is another way to say supercharger, so saying you can bolt on a blower or a super... which by super I assume you mean supercharger... is a little redundant. What N/A mods are you talking about to make it "really radical fast!" per say?

When you say that "most every sports car has some sort of super or turbo so why not add one to a corvette?" Which sports care are you referring to? When I think sports cars, I think Corvette, Viper, Ferrari, Lamborghini.... Correct me if I'm wrong but all of those are naturally aspirated. I know the Lotus Exige S is supercharged, as well as for example the BMW 325i Twin Turbo and the Porsche 911 Turbo and Chyane Turbo... but the only other "sports cars" that I can think of that come with forced induction from the factory are imports, Supra's EVO's WRX's etc... The Corvette simply is not in the same league as these cars for many reasons. To say that "most" sports cars are force induction is just simply not accurate.

Now I don't know what you expect to get for "5 grand" for your "blower" but that isn't going to happen... Hate to break it to you. Unless you get a good deal on a used Procharger or Maggie... install it yourself and assuming you already have the means to tune it your self... Thats assuming you already have the supporting drive train and fuel system mods.

You prefaced your statement with "i don't have any hard facts or first hand experience but." You were correct with that statement. I know I have been a bit brutal with your comments but you need some proper information if you are considering this yourself.

To Luca... You have been given some other good advice on this thread... their are many ways to skin a cat... Personally I went the Twin Turbo route... Thats only one possibility. Check out the Forced induction/Nitrous section of the forum, lots of good information over there. Good luck with your goals, try not to chase numbers, just enjoy your car for what it is. At 500HP you are at the limit of what most of the stock drivetrain can handle, and if you have a stick, you will need a clutch that can take the power.

 

Either a really aggressive heads/cam/exhaust package and you may or may not get there or just bolt on a blower! Which route are you considering...N/A or FI? Either way it's not going to be cheap!

 

The answer (to 500+ HP) has a LOT of options.

Do you desire NA, etc. are critical.

For me: I went NA with a LPE (Lingenfelter Performance Engineering) 427.

I chose this route (after taking a number of other methods first) because of the NA capabilities - I felt that since there were less "additional" parts on the engine - I.e., S/C, turbos, etc. - there are less "things" to break.

I make 519+ RWHP, more than enough.

If I were to do it all over again - I would elect to go with the LPE package the S/O has. LPE H/C, Kooks headers, Gold Luc clutch, underpully, 4:10's, etc.

Her's makes 440 RWHP (this was done on a day the temp was 103 degrees ).

Price was 1/4 of mine (the 427).

It is much more 'friendly' to drive - the 427 is a real beast (but a lovable one) and is really too much HP for the street (I don't track her - been there - done that).

Hope this assists - do yourself a favor and determine the HP package based not on the numbers, but on what will suit your needs best.

One way to do this is contact the various Forum tuners and talk to them. I have found John Page (21st Century MC - LPE) to be a person that can assist anyone in determining his/her needs without trying to oversell the customer (his number is (972 417 7177).

 

Like I said. I have asked some questions and got some responses and this is some data I am regurgitating based on things I have read on the board. I don’t mean to spread false info.

 

Call A&A or ECS and slap on a blower and 500rwhp is a walk in the park and boost is addictive and always there when you press the go pedal

 

346 motors have made 500 rwhp before. Its not impossible.

 

are there any performance/mechanical advantages to a NA engine?
