Hello all

I have seen results posted with AFRs and stock LS6 cam but does anyone have results with AFRs and the stock LS1 cam?

I am just curious what the gains would be with AFR's milled to 11.3:1 running a stock 98-99 vette camshaft with tuning.

Would 40RWHP gain be out of the question? (AFR 205's replacing a stock LS1 head)

Any special tuning considerations?

It'd be nice to have an extra ~40 RWHP without having to worry about emissions, spring life or lifter failure.

Chris,

I think that 40 rwhp is within the realm of gains, even with stock cam. Vinci Hi Performance has done some of these swaps (AFRs with stock cam). Personally, I don't think you'd give up one ounce of reliability be swapping in a quiet LS6 cam while you're at it.

But to answer your question, stock cam will work well with the AFR 205. To get the most out of it, I'd still recommend a razor sharp tune (to keep the fuel economy as high as possible and the WOT in the lean range with good timing). Your BSFC should improve with the better efficiency of the heads so why not tune it to extract ever last hp while keeping the exhaust squeaky clean?

here's the vinci PROJECT AFR 03 corvette. the very first mod was the AFR 205 heads. made 39 rwhp still on the stock tune. the one difference between the 98-99 vs the 03 is the intake 98-99 has the LS1 intake. the 03 has the LS6 intake.

IMO, your leaving alot of potential hp on the table and your not getting your full moneys worth from AFRs. Its like buying a Mercedez s500 class but never touching all the options it came with.

Get a cam with it...its all about combination!

279/298 is the lowest dyno I have ever seen on an A4.

I would throw in a sleeper cam, but the gain from the heads is good either way.

the LS6 cam is usually worth 20+ horse over the stock cam-so I would say you would leave alot on the table and the AFR's wouln't perform as well as they do say on a LS6 due to the lack of lift and duration.

quick question...would the cam that came from an 02 vette be a ls6 or just a regular ls1?

Don't make me drive all the way to the frozen north and bitch slap you.
You know damn well that you can add a Z06 cam, 212/218, 216/220, or 220/224 on XE ramps and pick up good power, not have spring life or lifter issues, and pass emissions easily. Don't drop $2k on heads plus invest in tuning and stay with a stock 99 cam.

AFR's with an LPE GT2-3 would be a stealth street terror.

If it's not a Z06 it has an LS1 cam. It would have the LS6 intake though.

U guys have me so convinced that these AFR's are worth 35RW I'm trying to convince myself into spending 2K for them...I run a 214-222 559-566 115+4 threw shorties and an X pipe and want the best head for the $$$$$...

So far its...
AFR $2,150
TEA S1.5 $1495
Dart I can buy them cheaper than Jegs
Patriot 5.3 $1095

I need at least 30RW from the head that I run
I wanna make 370RW threw shorties and a A4 with this small cam
I would add the LSX/90 if its worth it down the road..

JS we have spoke many times and another thought just jumped into my head.
Before while we were talking I was trying to tell you my oponion of the best head for the money but something hit me just now that hasn't hit me in the past. Your goal is only 370 RWHP. The cam choice you made is more/less similar to a Z06 cam. With a LT header and good exhaust I did a A4 2002 Z28 with stock heads, yank 3500 converter, and all boltons. He made 355 RWHP using a Z06 cam only. That was with 10:1 CR. I bet that he could have made 370 by just using a stock Z06 head, and a .040 gasket.
With that being said, I almost want to say the PP,TEA's,AFR's,Darts,PRC's etc will make you achieve your goals.
IMO from talking to you I got the impression you were after HP per dollar.
If so I personially believe AFR is the worst choice based on your goals.
Go buy a set of Darts or TEA's for 1300 bucks vs 2200 for the AFR's. Then go into the for sale section and grab yourself a 90/90 combo for 1000 bucks. Now your spending almost the exact same amount but are geting more value out of your money. On the back side you can sell you stock LS6 intake and TB and make 400 or so back which would acturally make the heads, 90mm intake, and 90mm TB cheeper then just the AFR's.
Now if your goals were higher and money wasn't a huge factor AFR would be a strong choice.
I would bet 1000 bucks a set of TEA 1.5's and a fast 90/90 combo would make more power the a set of AFR's with a LS6 intake and TB.
