whats the least expensive way for makin about 450hp to the ground on a m6 C5? 98 or 99 model, I'm thinking cam, headers, exhaust, and cold air induction.. what do you guys think? what cam? ect??, thanks

 

You will not get 450 to the ground witout heads. I know alot of people will say trex cam but reality is , THat was only one car that made that much power with the trex cam and everybody else didnt come close. IMHO

 

w/ the proper cam and a set of stock 5.3 heads (higher compression), do you think it would be possible?

 

If not, i'd say you'd be pretty close. W/ heads, cam, full exhaust (long tubes, mid pipe, cat back) a lil tune, CAI and maybe tweeking up to some LS6 components like the MAF or TB and you'd be damn close if not a tweek over.

I think it'll be hard to get 450rwhp w/o doing some kinda head or CID work, but with the right tuning and all, you'll probably be really close.

 

lets try this for starters...

LT's w/ unrestricted flow into a borla cat back $1000
some kind of cold air induction $80
stock 5.3L heads w/ stiffer springs (compression??.. 10.6:1?) $500 (used)
chromoly pushrods $140
LS6 MAF ?
LS6 TB ?
230/230 560/560 112lsa (something like that??) $350?
bolt kit / gaskets ect.. $120
tune $120
now does the 99 C5 have the LS6 intake allready?
w/out the TB and MAF its at at least $2230, now if it would be possible to get 450hp out of 2500 bucks, that would be kick ***, and then a loly ol' 100shot would be the final step for some nice power w/ not too much money spent. any other thoughts or details I f'd up on?

 

your pricing is crazy low unless your buying all used stuff!tuning alone will cost a min of 350$ the TB is the same on all vettes as far as I know.that yr Vette will not have a Z06 intake either,but you could score one of those for around $350. Do the stuff your talking about minus the heads with a cam that has a larger ex. lift than in. for your juice and you will be over 450 on the bottle with your stock heads(you will have to upgrade springs and pushrods with any bigger than stock cam)...

have fun with the budget Rocket!

 

N20 is the only way to go, my car makes 416 with cam and headers

 

i have a set of flp long tube headers on ebay with high flow cats and x pipe

no, the whole point is to get 450 w/ OUT n2o!, the n2o comes after the inital 450 is acheived!

 

Assassin,
be ready to open your wallet if you want 450 at the rear.also that seems like a good buy on the FLP's from ITSovr4U.!!.

 

My mistake on who has the headers-sorry pdd-it is still early

 

I would say closer to $5k for everything, that is mainly NEW pricing though...

There is some kid on the corvette forum that got 460 rwhp and 440 rwtq with heads/ 230 cam, and bolt ons, but NO headers!!! It really depends on your setup and quality of stuff....... I have found out you get what you pay for within reason....

 

Geez: Heads alone is gonna be $1000 at least if you find one luckily on ebay or something for someone going from p&p stock heads to a complete new set of aftermarket heads. Then they need to be some radical heads, at least a stage II p&p on them. That FLP full exhaust for $900 is quite the deal, and I would have gotten them if I had seen them. I love my SLP long tubes, but his has the cats and x pipe and all, where mine is stock piping from the cats to the catback. That only offers maybe 5 hp more than my setup, but when you are going for what you want, every bit counts. Then when you get that exhaust, get the B&B straight tips, without the mufflers. Maybe a LSX intake with their larger 80mm billet throttle body may have to be in the works, then a heavy cam for sure with crappy idle habbits. No only 2001 and above come with the LS6 intake. So since you gotta get a new intake anyway, get the LSX which will run you $650, the cheapest I have seen them so far, compared to a $300 used LS6 intake that you will have to run down. On the intake get the Vararam for sure, with the K&N upgraded airfilter since theirs is a POS!

Now maybe you will have 450hp at the tires. This same setup I seen on Floyds Z06(Corvettes owners group here in Vegas) gave him 440hp at the tires, except that the LSX throttle bodies are not out yet, he has a ported and polished throttle body, on it now, a 2001 and up descreened MAF, which is 5 mm larger than the 2000 and earlier. The new MAF has the air intake temperature sensor in it also, so it is a pain in the *** for the rewire on that according to him. I don't know how he got that done since there are two different plugs on the 2000s and so for the MAF, and IAT sensor. Now that was dynoes here in Vegas, so his setup would have 450 at a lower altitude.

LSX intake..................$650
Stage II or III heads...$2500(depends, 10.5 to 1 or 11 to 1)
Comp cams kit.............$600
FLP's from ebay...........$900
B&B exhaust...............$300
P&P T/B.....................$150
High flow intake...........$250
Dyno tune..................$350(if your lucky)
Gaskets.....................$195(Heads, intake, water pump, timing cover, exhaust)
New Head bolts............$65(ours stretch and can only be used once)
Labor......................$1500(if you get everything done at once, and they like you!)

Total: $7210.00

Hell, C/Motorsports has a stage 5 kit installed for $6500, which does not include the LSX intake, but has everything else listed. They say that average HP to the wheels in Vegas is 400hp with this kit. I have met 2 guys so far with these setups and both got like 397 hp at the tires. Again take it to Cali, and they are at 420!

In my 2 cents, there is no cheapest method!

 

alot of the parts I wuz talkin about would be used, I make my own bends and welds for exhaust pipeing, if any muffler at all it would be Borla, I've done track testing w/ them and they trap the same mph as open LT's on a carbed sbc, but much much better bottom end, a buddy of mine owns a dyno and gets all his tunes from diablo, I perfer ls1 edit though, I've paid about 160 for complete gasket sets including new head bolts and header bolts, I have been workin on the ls1's for quite some time now so I'm no newb., some of my prices may be cheaper due to the buisness accounts I have opened up, .......

I'll bet, that useing a stock LS1 w/ an M6 and putting 3k in horsepower parts (not includeing clutch, tires, ect..), I can get 450hp n/a out of it..... this is with myself doing all the work, and not have to pass emmisions!, and it dosent matter if the parts are brand new or used (I also would have to show proof that no other extensive mods were done like pistons, stroker kit, or anything I dont have receipts for)....... if I win you pay 3k, if you win... I give you all the parts I bought + cash adding up to a total of 3k.... any takers?

 

Assassin, it is guys like you that start airlines thinking they are gonna make money. Go for it. It hasn't been done by the absolute best in the business with the best equipment. What makes you think you are better than them.....with inferior used equipment? Good luck.

 

I'm a little confused Assassin, didn't you originally post the question? Now you are the expert? Why post a question you know the answer too?

 

Sorry, I didn't know that you had connections and what not, and had the ability to port and polish your own parts and make your own exhaust, if so that is great for your behalf. Since you posted the question, and I have been studying this stuff for crazy over the last month for my application, I thought I would chime in and tell you what I have learned and seen on pricing.

I wish I had some real great hook ups, It took me a month of heavy searching to just find Z51 springs for mine for $400!

 

I posted the question to find out who also has done this, and if you look at the post date it wasnt posted yesterday, and I now have my answer, thanks for the replies, and sometimes you need a challenge to get off your *** and do something,

lol, I'm sure the best in the buisness has acheived this a long time ago, especially w/ the amount of money they have




allright, look at it like this, is it possible to get 400hp out of an ls1 w/ stock heads (lsx, headers, proper cam and tuneing, underdrive pulleys, ect. ect..), well if you can hit the 400 mark on that, I'm sure a set of stage II heads will get you an extra 50hp on top of that(there wuz a recent dyno that gained 70someting on just the heads), this is just an example that the 450 mark n/a is not out of reach, if it were 500 then i might not want to even try.

 

Hot Rod recently ran an issue of some of The Fastest LS1s out there.

Fastest Cam Only - 10.93
Fastest H/C car - 10.50
Fastest 6 speed - 9.88
Fastest N/A - 9.65
And outright fastest Ron Duke - 8.52

That cam only car (altho im sure its got some other mods besides "just a cam") put down about 410rwhp, so im sure w/ a good set of ported heads you could be close to the 450rwhp mark.

 

Yeah, 400rwhp should not be a problem with cam only plus boltons. There are a few on this list. It seems the benchmark for Heads and Cam for an LS1 right now is around 475rwhp....that is the top tuners in the country(CARTEK, LGM, Vette Docs, etc.).....fairly aggressive cams. Good luck, Bro and have fun.
