I would like opinions on the best cam for my A4 lunati stroker.My current cam sucks. I have all the bolt ons, LS6 intake, Stage 2 A.R.E. 2.055 heads, 1&3/4" grotts, 2800 stall,etc... I"ve heard 227/230 what lobe lift? and gross valve lift? I just got in the mail a 228/228 comp cam .588/.588 .3460/.3460.is that close enough to max hp? My goal is 600 hp at the motor (480rwhp ). Can it be done with H/C bolt on stroker? Experienced opinions would be greatly appreciated. thanx <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />

 

244/244 .610/.610 114 lsa is in my stroker and it idles smoooooth. Easily 480 RWHP.

But I'm not that experienced, I could be missing something here.

I dont have an a.r.e. super stroker.Its just the lunati 382 stroker kit.Wouldnt a 244/244 .610 be a little big? The .610 would be hard on the springs right? I have comp. 941"s in. Could they handle .610?

 

IMO, 480 RWHP from an A4 stroker is unrealistic. Yes, we've seen close to that from a LG 346 set-up, but that was a complete matched package with a pretty trick exhaust. Strokers make great TQ but don't seem to gain as much as top end HP as the big bore set-ups. The 228 cam should make pretty good power and still have decent drivability. With ARE heads, you might consider ARE's 232/236 112 cam if you want more power (and have notched pistons).

If you want more performance, going bigger than the 232/236 cam may give a small gain. Going from your PT 2800 to a bigger stall such as a Yank SS 3600 or 3800 or TCS 3800 will have a much bigger impact. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

I think 480rwhp would be difficult in an A4 as well. I am close to that number but in a 6 speed. I am running the Grand Am Cup cam: 239/251 .570/.570 l06.

 

I was thinking about 480rwhp on my a4 422ci block. I do not think that 480 is going to happen on a 382ci. Maybe 450 rwhp with an a4. I would look into the 232 237 .575 .575 114 lsa that lunati makes. It will give you a lope on the idle, but will not require the upgrade on springs. My friend uses this on a 370 ci m6, and it is a great cam. He dynoed 452 rwhp and 429 lbft torque SAE corrected.

 

Thank you guys . I have had a really hard time getting advice. So I should send the cam back, and go with the 232/237 .575 114. Do more of you think the same thing, or real close to that cam? BTW the pistons are the ones that came with the lunati rotating assembly, I dont know if they are notched or not. The car dynoed @ 339rwhp , & 350 rwt the current cam is a 205/212 .540/.540 ( thats with maft & 100 octane ) It broke my heart the builder picked the cam,with the help of rob crest from lingenfelter. It had more hp when it was just h/c, alot more!!!

 

Do you need to pass emissions?
no ->i'd go in the 230's on duration, mid 230's would work.
Do you drag race a lot?
->if not then you might want a mild combo.
What compression are your heads?

I made 472rwhp with a 422ci iron block A4. I also made 505rwtq which is a lot compared to most folks.

I think 450rwhp/ and 450-475rwtq is possible with a thumpy cam.

Sure 346ci's have made 440rwhp and more but they don't make 450rwhp by 4000 like my motor did.

I think id like to go with the big mti cam. I would be totally happy with 450 rwhp & 450 to 475 rwt. Right now im at 340 rwhp & 350 rwt. I HAVE ANOTHER QUESTION; is there any difference between a 3800 precision industries vigalante ( which i have in the car, but would have to send it back to get them to change it for free ) & a yank 3800 stall???? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

man i cant quite get that highlight the quote thing down;;; any ideas as to how to do it right? <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

 

"With ARE heads, you might consider ARE's 232/236 112 cam if you want more power (and have notched pistons)."

That's the cam that I ran in my stock engine, and that's the one I'm going to start out with in my 393 All Bore that ARE is building right now. The engine is being built to handle a huge shot of nitrous, so NA power levels will be down.

With all the bolt ons, very similar setup to what you have, I estimate power to be in the 440-450 range, NA, 750 on the spray <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

If you are NA, then I think 450 is about what you could expect. If you went with a more radical cam, you might pick up 5-8 more HP. I will be switching out cams later in the year, to see how it reacts. I'll go with the most radical one that Wade recomends. I think that the 232-236 will be better on the street though, and with a 300 shot, I'm not going to be too worried about the 5-8 HP I'm leaving on the table by not going with the bigger cam. After I switch, if the bigger cam doesn't produce significant gains on the spray, then I'll be switching back to the smaller.

You are def under cammed right now. Give ARE a call & see what they say. Good luck.

 

First thing I would do is toss those 941's, I also have a 382 with GTP SII heads with a lunati cam, specs are 237/242 .595 lift on a 112 lobe sep. I have broken 5 on the 941's, They would have been long if I wasnt here in lala land. It does make awesome power though, just havent had a chance to dyno it. Best of luck with your setup.

 

mike 2002, How did she idle with that cam??are you an a4?

 

also what springs should i use?

Unless you're talking about a small stroker being unrealistic.

You and "TXNC5" haven't read my thread titled, "ARE 436 & stuff 30-Day update).

My ARE 436 FLP IV 4L60E A4 at Norris Motorsports last month made 480 RWHP just before reaching 5,000 rpm when the factory fuel pump lost 3 psi of pressure. At that point in the run the RWHP was climbing FAST, at 5,000 rpm it was pulling 485 RWHP but then quickly dropped another 10 psi of pressure and Mike Norris aborted the run.

After I get the Racetronix fuel set-up installed I'm pretty damn sure I'll see over 500 RWHP. Best thing is the motor idles like stock with the 244/244 .610/.610 114 lsa cam, I can go bigger if I wanted to and still be streetable.

Another guy in California has an ARE 436 identical to mine except he has a 240/240 cam. He was making 453 RWHP at the 5,000 rpm mark and a total pull of 496 RWHP/505 RWTQ @ 6,300 rpm.
I'm 32 RWHP ahead at the 5,000 rpm mark.

Do you think I'll go over 500 RWHP???? I think <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
