Default 400 Rwhp possible?

Is 400 rwhp possible with stock heads, stock internals, headers all of the other bolt-on's and a new cam? And if yes what cam is it?

I'd probably say 400 on stock heads is kinda pushin it. not n/a anyway. I'd say the best youre going to see, is probably around 360-380 or so rwhp. I could be wrong, but thats just my assumption

How about making that kind of hp and still being emissions legal in CA?

400 RWHP + stock heads + CA legal = forced induction

I beleive the original post was for 400 rwhp with all stock internals (that means no cam!)and all bolt-ons. I think Ling_650Vette hit it on the money. Im pushing 370 rwhp with all the bolt-ons except for the Fast Toys ram air kit which I will be getting soon! I dont think it will bump me up to 400 rwhp, but I could see maybe 375 or 380 rwhp. I have never touch an internal, but Im thinking of doing a cam, and for sure Ill be at 400 rwhp! Hope that helps! By the way, I think that a M6 will have more of a chance than an A4 due to drivetrain loss.

He specificly said with a cam. I know, not stock internals technically, but he did ask.

Well with stock internals...NO! With all bolt-ons and a cam...YEAH! However..Im sure that not just any 'ole cam will work. Im sure you have to get a decent cam for it. Not only that, every car is different. Luckily, my car pulled some good numbers being internally stock. Im probably gonna go with a 224/224 with either a .561 or .581 lift on a 112 LSA. That should bump me up to 400 rwhp! By the way...I gotta get some more adjustments done to my PCM because I think there is something wrong with my air/fuel ratio causing some retard. There seems to be some power loss in 3rd and 4th around 5k rpm. Hopefully when I get it fixed that I will pull a 'lil better.

OK I guess I didn't specify when I said stock internals, which I meant stock heads and stock bottom end, my bad. I would be happy with 380 rwhp for now untill I can do a full head and cam swap.

The point I was making too is that autos aren't dyno queens. THeir hp rating is lower on a dyno cause the trannys use that hp differently. But autos can get REAL aggressive with stall, and gears <img border="0" alt="[angel]" title="" src="graemlins/gr_angel.gif" />

so 400 on an auto with stock internals i'd just say "no-can't do it". But you can cut 1.7 60' times all day long!

at 325 rwhp i can beat the 400hp m6 to 1/8 mile cause of the hole shot but he'll take me on the big end when he gets into his hi rpm's in gears 2-3

GET NITTOS AND LCA's heat the tires and HOLD ON if u got 4000 stall!

YOu can ask on ls1.coms parts wanted section for lca's I had 3 guys offer me their sets for $50

So what is the closet I can get to 400rwhp with an A4. What cam is going to get me the closet? And I will have a St-4000 also. I am also figure new spring, pushrods and possibly rocker arms.

I dyno right at mid 310s right now and cut low 1.7 60's. Question is, what do you want out of your car? Just dyno numbers? Do you want killer times?

It is entirely possible with Stage I heads (possibly Stage II) and a good "mild" cam with tuning. But that is a different issue than the original post. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
