Hey guys, I need some suggestions on a different cam for the mods that i have now. The car was built at Rapid Motorsports several years ago, but the car used to belong to capt99ws6. Its a 99 NBM WS6 A4. The reason im asking for cam choices is because i dont think that the cam that is in right now is matched to the heads and everything very good. Here are the mods. ( Ignore my sig., old car)

Engine:
ARE stage 2 heads (2.08, 1.60)- very hard to find any info on these!!
LS6 intake ported
SLP 85mm MAF
underdrive crank pulley
Hooker LT's
Hooker ORY
Magnaflow catback
Volant intake
Lunati 226/226 .560 114lsa
160* t-stat
ARE high volume oil pump
NGK TR6

Drivetrain:
Vigilante 3800
B&M trans cooler
3.23 (but would like to go with 3.73 soon)
trans is bout to go but it will be replaced with a built one soon

Suspension:
BMR subframe conn.
Spohn LCA
Nitto 555R

The car was dyno'd at 375 rwhp and 357 ft-lbs, best time was a 11.83 at 113.98

All these numbers are from like 2002 and i just feel like there are better cams out there now that will make more hp and tq that this! I would expect at least 400 rwhp with this combo, ...am i wrong??
The only thing i want to change is the cam, but i dont want to have to flycut the pistons! I know these heads are real big, but can they make more power under 7000rpms with a different cam??
Any help is appreciated!!
Thanks!!

numbers seem kinda low.I put down 417rwhp an 407rwt in an A4. here is my set up
MTI lid,Slp maf,NW 90mmtb,ported fast 90,Tr224/112cam,TSP stage 2.5 5.3L heads,hedman LT hedders,ory,dynomouth,TCI ssf 3500 stall,RPM level4 tranny,3:23 gear.
Maybe a ported fast will help,i dont know,but hope it gives you some sorta idea what you should put down

yea i thought the numbers were low too, well it will be gettin a new tune soon (even if i dont swap the cam) so we will see if those numbers are correct, Thanks

get a new tune and go from there.My cam is smaller than yours,so that may not be the problem. Hope fully someone like Pred,or pat G will comment.

For having that high of a stall and going to 3.73 gears soon, that cam is too small. Not to mention too little lift to better take advantage of ported heads. I would go with a TSP 228/228 at minimum, or any other proven bigger cam performers: torque cam, g5x series, etc. You can go big and sacrifice low end on the cam, because when you get on it or race w/ that torque converter (and soon 3.73 gears) you're skipping right through the low end rpm range anyway.

im just worried about ptv clearance with a higher lift cam because of the bigger valves
should i be?

well,

you say your only making 375 to the wheels, but you ran 11.8 @ 113, thats nothing to sneaze at and i dare say most cars making 375 dont run that fast.

The real question is what do you want from it, faster track times, or higher dyno queen numbers?

As far as selecting a cam, since you dont know much at all about the heads your gonne need to clay so you can see the ptv clearance with whatever cam you select.

yeah those numbers were with the previous owner, but i haven't had a chance to take it to the track or dyno. it needs to be tuned but i dont want to have it tuned and then decide to put a better cam in and then dish out another 450 bucks for a new tune. i dont really care bout having the high dyno numbers, i want more useable power for the street, but better track times wouldnt hurt either. i wouldnt care if it didnt hit a high peak hp or tq, as long as i could get a good number across the board, in the street rpms. will my stall let me do that?

I had ARE heads very similar to those. The heads are stone age in performance compared to a even a budget new head today. The ports are large. My experience was that I made nearly identical power to your results with almost an identical cam. What I did notice was that my power carried very well in the upper rpms. I had 1 7/8" headers which contributed to that, but the point was that I ran good times despite the lack of peak dyno power by shifting at 6800. If your dyno results show that your cam carries well in the high end, then I'd that's what I'd shoot for. Chances are the heads were milled to bring the CR up to 10.8:1, so don't go crazzy big. 230/230 111 111 would probably fit (very minimal IVO change) and take you from -2 overlap to +8, so you would gain a decent amount of power.

If you are changing springs, I'd probably look at the 231 LSK lobe for the intake and an XER on the exhaust. You'd really pick up a lot of intake area even though the duration is just 4* more.

wow! i didnt quite follow all of that! I think the biggest thing im worried about by going to a bigger cam is the ptv clearance. im not sure if the heads were milled or not, but the previous owner is supposed to be gettin me a copy of the build sheet that shows all parts installed and spec. i cant even find anything on the heads(markings) to show they are ARE. the only numbers are 231 on the passenger head, does that make any sense??? i guess my best bet will to prolly get a custom grind from patrick g so that i can get everything matched to these OLD heads!!

At least tell the man your numbers are with a locked converter

No not yet I usually work second shift 11-9.I get more personal days in late july,so i may burn a few of those days for test and tune to see what it will run.My friend gillbot puts down 400rwhp and 360rwt and runs 11.8.Im hoping to do that or better.I dont have alot of experience like he does.So wish me luck
