LS1 vs LS6 cam dyno graph A couple weeks ago I asked about putting an LS6 cam in an otherwise stock 99 LS1 A4 F-body, stock tuning, etc. Well, I found a 2002 LS6 cam and LS6 valvesprings used for $150, and put them in this past weekend. My GF wanted more topend power, but OEM reliability, and that is what she got. I'll probably bump up the shift points and rev limiter in a few months.
Anyway, the topend really shows what the LS6 cam can do.
BTW, as others have said, even in the A4 it idles exactly like stock. I doubt there's anybody on this board that'd know it had a cam from just standing behind it.

Re: LS1 vs LS6 cam dyno graph I think thats a damn good improvement for a factory cam swap. Is her car completely stock?
This is the first dyno I've seen from just an LS6 cam swap on a nearly stock LS1 engine.

Excellent info Jon. I don't think anyone here is crazy enough to swap a cam on a stock car, and then dyno it! She needs some headers next

Re: LS1 vs LS6 cam dyno graph
Ahem, what about adding heads & a cam to a stock car then dynoing it?

I resemble that remark! :p
Now your girl has more NA power than I do!
I'm still using factory cats, exhaust manifolds, intake, and TQ convertor, so that gain is right up my alley!
Nice info Jon thanx for posting!

Re: LS1 vs LS6 cam dyno graph The best acceleration with the Z06 engine involves shifting at ~6800 with a stick. Bump her up, up, up. I've seen a couple guys run the Z06 and only pick up .1 in the quarter with an A4. Why? If the trans shifts at 6000 in 1st gear, RPM drops to ~3200 into 2nd.

Re: LS1 vs LS6 cam dyno graph Look at the curve at <4200. You Are LOSING HP for 1/3 of time you are in gear. Now if you shift at 6800, still it drops to 3600'ish, but now you are losing power only about 1/5 the time you are accelerating.

Re: LS1 vs LS6 cam dyno graph This is why everyone ragged on the LS6 cams, because they were afraid to spin the motor. I'd venture at guess that at 6200 rpm (LS6 peak) you will be 50rwhp ahead. And that's a chitload.

Re: LS1 vs LS6 cam dyno graph It's the RPM drop between first and second gear that kills you. With 4.10's the rpm drop duration will be shorter, but it will still fall to the same RPM. You will have a great 1/8th to 1/4 time split, but a lousy 1/8th mile ET.

Re: LS1 vs LS6 cam dyno graph I will very much disagree with your 50rwhp comment, but yes, obviously a cam is only part of the puzzle for optimal performance. I figured that went without saying.

Re: LS1 vs LS6 cam dyno graph An LS6 engine vs an LS6, sure, we're talking about just the cam! The heads have something to do with it you know. Putting an LS6 cam in a stock LS1 is not going to give you 50rwhp, and that is all I was disagreeing with.
A stock A4 with stock converter, and stock everything else is not going to gain half a second in the 1/4 just from the cam alone.

Re: LS1 vs LS6 cam dyno graph I think McRat is right, on the 50hp thing. Its right there on the graph.
If you look at the 6K mark the stock is almost at 275 and the LS6 hasn't even peaked yet and is almost hitting 325.
Thats a nice sleeper cam!!
