I think I am going to go with the headers and cam with tunning I got a little nervous with the last reply that engines have blown with that mod. don't have much $$$. to put for a new engine but if it did go would get a 427 block and start from scratch and bullet proof it. :cheers:

 

If we can help in any way, give us a call :seeya :seeya

 

If you go with Lingenfelter. They sell the Magnacharger, which also requires a new hood. The SC pushes 5# of boost and is supposed to generate about 490HP. They will do the entire package, plus warranty the work for 2 years ($200 extra).

So, in this case you will have to pay Lingenfelter $8700 plus you should get the gears, Torque converter, and tranny cooler before hand. I listed the prices for each of these earlier. So add it up. . .you are looking at some serious cash. you could go with a head/cam package for about
1/2 the price. :D

By the way, I am in the same position as you. . .I am trying to decide which mod to go with next. :D

 

yeah, but digging into the engine is alot riskier than just bolting on a supercharger. i'm with fairway on this. problems hooking? thats not really a problem as far as i'm concerned. i'll just keep buying Nittos until i can afford 345's in the rear. ;)

 

When I said, "problems hooking up", I meant that you will have all the HP but you will NOT run times like a car with that much HP should run. If you have stock gears and a stock TC you will run 1-1.5 seconds slower in the 1/4 mi. Nittos won't help with that.

Otherwise, I agree that going with the Lingenfelter package for $8500 is a great package. They will even test and tune the car. If I were going to go w/ a SC that is certainly the way I would go.

I am not sure that I agree that a head/cam job is so risky. I would have to defer to some of our excellent vendors for help on this one!

:cheers:

 

aah ... ok. i misunderstood. and you are of course correct about TC and gears. :) :cheers:

 

evil-one if I was you I would try to find someone in that area that has both setups and see and feel the one you like the most as I have cartek H/C but another CF member let me drive his S/C 99 hardtop it would have no problems blowing me away on a roll on maybe a dead stop it would be close for a couple of seconds then the S/C kicks in about 3200rpms and it pull like the :reddevil if you can just go for a ride and see how you let it.

 

What supercharger did the guy have? What kind of rwhp/rwtq numbers are you getting out of your head and cam package? Do you know what his dyno numbers were?

:confused:

 

...80mm TB, 38lb injectors, LT headers and tuning, good bang for your buck.
If you have some spare cash go foe 3.42 gears as well...

..... :reddevil ..by the way, nice name.. :reddevil .....

 

Here is the forum post to the Vette Drs "Headers and Cam" pricing

You have gotten some good advice here and a few views on costs.

The question you did not answer is your end goal. I know we rarely know today what we might want a year from now but if your short term goal conflicts with your long term goal you will pay more in the long run.

You have lot's of decisions to make. Take your time and do in the end what is right for you.

 

Hogurt my car was making 400rw and 375tq the S/C vette I drove has 520rw/460tq it is a blast to drive. :yesnod:

 

Well, that doesn't seem to be much of a fair comparison? If you wanted to compare apples to apples, for the price of a blower you should probably compare a stroker motor instead of a head/cam package. Afterall, the price will be more comparable along with the HP/TQ numbers.

At any rate, the SC's rock! I personally like the sound of the normally aspirated engines more. . .but, that is just an individual taste thing. Noone can argue with the HP results! :yesnod: :yesnod:

 

I'm just saying for about the same price you can have a S/C I will see how my new A.R.E all bore pulls against the S/C as I like the N/A too.

 

actually, i think it is a fair comparison. and heck, even the prices are similar. if you price a complete "stage 2" h/c package from MTI, you'll probably be out the door at $7000+ after you add up, heads, cam, pulley, timing chain, pushrods, dyno tuning / pcm programming, labor, etc. an ATI tuner kit, parts and labor, is going to be about $7000 too. yes, i know that you can go with cheaper parts (i.e. $999 heads), cheaper tuning, etc, but why take the risk of trashing your engine?

anyway, price is only one factor, and it varies alot depending on the parts, options, tuner, vendor, etc. heck, if you're going to compare h/c to s/c, then you should probably factor in all bore / stroker motors too, because you can find those for under $10k. :)

 

Ok, now I think we are saying the same thing. I will take your word on head and cam packages. Although since it is what I am looking at doing. . .it looks to me like I will be able to get a Lingenfelter head/cam package installed for around $4k.

My only point is that a stroker motor is probably closer in price and HP numbers and thus a better comparison. Otherwise, I agree with everything you are saying. Believe me, if I could get the financee to agree to a SC. . .oh baby!!!! I'd be all over the ATI. :yesnod: Unfortunately, if I went with a SC I would probably be without a finacee. :nopity

In my case, for about $3-4k less, I can get a head/cam package and keep the girl!!! :cool: :cheers: :cool:

:reddevil So what do you think about a head and cam package. . .with a supercharger added later??? :lol: :reddevil :lol:

 

hrm ... yeah, you can do a heads/cam package out the door for $4000 probably, but that is not going to include a replacement timing chain is it? the stock timing chains are really weak. how about a pulley too?

you got to keep in mind too that you are probably more likely to be buying a new engine or making major repairs sooner too. i don't have numbers to back me up, but based on reading this forum for almost 3 years, and talking to alot of veteran mechanics, it seems like h/c is alot more problematic. all of the tuners i have talked to have told me to do s/c or turbo, and leave the engine internals alone if at all possible.

also, if you do a h/c now, you'll probably want to switch out for a different cam for the s/c. more parts and labor to keep in mind.

 

tattooed,

I know of dozens of Vette Doctor customers who have H/C on their C5 and do not know of any that had a total engine failure! Are there ordinary repairs required like a rare spring problem? Yes, but they are few and far between. Carmen and Dennis' Warrantee usually cover this type of repair. They provide a 3year/36 month commitment on their heads and cam package.

I really think you are over blowing your comments regarding risks of H/C. I had H/C on my C5 3 years ago and made over 150 1/4 mile runs and put 10,000 miles on mine over a 18 month time span and NEVER had 1 issue!!

Evil-One,

You have to determine what is your goal and budget. Is it drag racing? If so, stay with a progressive engine build that starts with external engine bolt ons like cold air intake, headers, LS6 manifold and then go into the motor. Start with Cam, pushrods and springs and Tunning. This will cost about $3-4K (depending on what you already have installed) and get you about 380RWHP+ and into the high 11's. If you can afford it do the heads with better valves. This will give you another 20 to 30RWHP on a M6 for a total of 420+ RWHP and get you into the low 11's. You could upgrade to LS6 heads but now you are really dipping into your wallet.

If you are looking for very good dyno numbers and more power for the street, a SC maybe a good option. No one has put up good numbers on the strip yet (due to belt spillage) so that is why I am not recommending it. The Vette Doctor's are experimenting with a new belt design, which may fix this issue.

You are in PA, why don't you meet up with Edgar in NJ, He is following my incremental build example above and has done up to the cam. His car is very fast! :steering:

 

For me, longtube headers first, only because I don't have the ballz to do a H/C swap myself. But I think I have the bollas to do a Magnacharger install. ;)

 

:iagree: I am following Edgar. . .cam and heads boys! Cheaper way to go. :yesnod:

:reddevil Oh yeah, an ATI kit sure looks good too. Anyone want to install it for free? :jester

 

Thanks I am flattered :bb :lol:
