Grim Reaper

I installed a SLP Blackwing CAI, ARH headers w/ high flow cats and B&B PRT catback system. Had the car dyno'd @ 356 rwhp.

After about a year I did a head & cam package. Ran it back across the dyno @ 435 rwhp.

I personally dont see an air intake giving you 30+ hp, headers maybe but I just dont see it very likely. Also I wouldnt think it should cost more than 800 to install headers. I personally would ask for 300 if I had to do it again for someone. I figure I could do it in 8 hours by myself so Im sure a shop could do it in 6 or less.

Running here with Kooks Long tube headers, high flow cats, midpipes and Corsa Pace car exhaust. Probably picked up 30 HP at least with this setup. When you say you "...don't want a bad drone", this is the way to go for low noise at cruise and decent hp return on the investment. The choice of long tubes are not as important as the muffler when it comes to the drone.

Read the post again I probably didn't place punctuation properly and the wording may have confused you. The 33 hp is from an ad on the web site for the Halltech intake which is priced at $695.00. I am not familiar with this product. I can get long tube headers installed for $1295.00 at the shop that has done the work, tuneup and dyno work on my landspeed race truck. A tuneup is $500.00 if you have other work done and a cam change, one of their own grinds or your own choice is $2595.00 including rocker arm, vakve springs and pushrods.
Someone questioned if I wanted a ZO6 or 425 flywheel horsepower, I will drag race my car some at a 1/8 mile track and I will be satisfied with the 425 hp, I was debating on whether to trade a car that I knew had never been damaged or thrashed to death or trade it. If I traded I would be looking at a 02 to 04 and it would not make any since to trade unless for a Z06. One reason my car does not have but 20,000 mile on it was that it pretty much sat from 2005 until last fall because during that time I had a massive pulmonary embolism which I wasn't suppose to survive, then I was hospitalized for three weeks with a life threatening bout of sepsus. Then almost three years ago I had a very severe heart attack followed by three strokes within a month. I was blind, could not walk or even sit up and I had 100% memory loss. I was not suppossed to ever get any better, I was in a wheelchair until a year ago Christmas and used a walker until last July and because I was landspeed racing I practised on my balance until I could use a walking stick which I will always have to use because of Parkinson's desease and Rheumatoid Arthritis.
I have a lot of enjoyment from the forum and these threads but someone takes it a little to seriously and insuniated that I didn't know what I was doing and I have had to relearn lots of things. I have been dragracing for thirtyfive plus years and lots of the cars were what are knoe vintage Corvettes. I drove a car for a Dodge/Plymouth dealership.
When I got where I could get around I really wanted to get back into competitive motorsports and I had read in Hotrod Magazine and saw on their tv show about landspeed racing on the Maxton Mile in NC. I first ean there last sept. with my SS Silverado truck and after five runs I was very close to breaking a one mile landspeed record in my class. I was hooked, I had more work within the limits of running in production pickup done and went back in Oct. and was fortunate enough to break and set a record. I have been preparing physically and making more modifications to my truck and I leave in eleven days for Wilmington, Ohio to run the first ever Ohio Mile that will be covered by Hotrod Magazine and TV. I really hope it does not rain and there is not a strong headwind on the 28th and 29th. With the pain I have in my legs I doubt that I will ever be able to make such a trip again. That is why I am going to start working on I think maybe my fifteenth Corvette with six new Z28'S and about thirty 427, 409, GTO'S etc. mixed in between.
It would be next to impossible to break an NHRA record and no telling how much it cost and not counting the cost of the truck I have probably spent $7,000.00 landspeed racing to date and I will have the trip cost for Ohio where I hope to set at least one and maybe two records, but I am driving, caring for myself and having a hell of a lot of fun. If you make it to the end of this post I apologize for going so long but I get somewhat inflamed when someone questions whether I know what I am doing.

I should have proofed that last post before I submitted it but I was pecking away as fast as I could go. To clear up one more thing the number I used $1295.00 to install long tube headers includes the headers, gaskets, bolts etc. It is not just the labor.

American Racing 1 7/8 Headers, American Racing Off Road X pipe, Corsa Xtreme Mufflers.. Perfect IMO, its loud as HELL at WOT but on the Highway its super quiet, No Drone!!!


Also ARH's are the easiest headers I've ever installed on any vehicle. Worth the extra money for fitment!

TSP's into Z06 ti mufflers/

Dropped right in and sound great.

Can't help with the header question, but you should consider the Callaway Honker intake. I think the Honker and the Z06 titanium exhaust are the best engineered products available for the C5.

The Honker cold air intake has worked great on my car ...; a set of ZO6 mufflers is on my wish list.

garrell.770

What is the cost of the Honker intake and do you know how much hp it produces? Thanks for the post and the info. Right now I am leaning to long tube headers maybe American Racing equipment and a Corsa h-pipe and low restriction cats then maybe the Corsa extreme mufflers, this is kind of like a kid making their Christmas list.

AFE intake and Magnaflow catback on my C5. Intake and exhaust is not going to get you to 415. It's a great start but without cam and head work the only other way I know is FI.

I think you are right on with your exhaust choices.

The Honker is a real cold air intake that is certified 50 states smog legal and cost me about $500. it is very stock appearing and has a large filter area.

The Vararam is touted by many owners as the best for drag racing and it uses the C5 fog light area as duel intake ports.

They both add horsepower gains by the ram-air affect; but the gains don't show up on the stationary dyno. After tuning, my car comes up with 325 horse power at the wheels.

I checked my time slips before and after the Callaway install and the new intake was good with a .187 second loss in the quarter mile.

I have a Blackwing, Corsa X-pipe, and Borla stingers on my FRC.

I have a Vararam, Fast intake, LG Pro longtubes with catless X-pipe, B&B Route 66, and a tune on my hatchback.

I wish I knew how much power improvement these mods make. I'm sure they help, but I don't believe the ads. If you add up all the advertising claims you can make a really impressive power without opening the motor. It just doesn't work that way.

I do notice that the Borla exhaust is louder with more drone than the B&B even with headers.

Bluefire

Running a VaraRam B2, H/C, American Racing Headers, Corsa touring catback. Tuned and Mustang dyno'ed @ rwhp 420 rwtq 392.

Go Z06 and get the bypass mod done...you'll never go back to anything less.

I personally have 02 Z06 with AR LT headers, x pipe/cat delete and BB bullets. My car sounds...absolutely ridiculous. The attention factor (not that I really wanted it) went WAY up and people always just say "man, that thing sounds terrifying". I frequently go to ALMS races, and my car would fit right in out there by the sound. Totally awesome for sure, but may be too much for those not used to some noise.

My car is a 2003 and all I did was to put a 2003 ZO6 air-box, a K&N filter and I went with the Corsa 'Pace Car' cat back system. I like it while it's a tad loud at start-up but when I go on a long drive I really like the fact that it doesn't drone. I don't know. I like what I've got.

GreenDream

These are what I have. B&B Route 66.

B&B longtube headers are on my shortlist then maybe Magnaflow or Corsa cat back and x-pipe and over the axle mufflers.

jpandes

ARH 1 7/8" long-tubes, x-pipe and OEM Z06 Ti catback.

I think it dyno'd with a tune and a Vararam at around 386-390 rwhp...

415? maybe but not likely without a cam

Best Real HP of a stock motor with many bolt ons is about 380-385 RWHP with an MN6 or MN12
