I want to get confirmation that this is virtually impossible to do on a car with those given mods. This guy I know insists it can be done.

2001 SS M6, stock gearing with the following:

1. lid
2. TTS long tube headers
3. 224/224 .561/.561 112 LSA thunder racing cam
4. adjustable fuel pressure regulator
5. ls6 intake

Can I get some guestimates on what this combo will really make, and how much rwhp is a good estimate for this combo without the long tube headers???

In sum this guy thinks he can get 390rwhp without headers from the same cam Justin Sears used to get 398 rwhp......except this guy doesn't even have a ported TB, headers, pullies, CPU tuning, aluminum flywheel, or CF driveshaft!!!!

He thinks that the 5 mods I listed above will get him 410rwhp!!!!

He'd at least have to go open headers and inflate his rear tires to 50 PSI to even get near anything like that.

My guess? He be in the neighborhood of 370-rwhp. That's assuming a good catback exhaust too, since you don't mention one. If it's a 2001 car, the LS6 intake is a given. With a computer reprogram, TB and pullies... he'll make the 400-rwhp range... but I wonder if he'll ever make 410-rwhp on stock heads. I don't think many people have ever stood on that plateau.

If he says he made more than 370 with the mods you say he's doing... tell him you want to see the dyno sheets.

No way!! Tuning and headers is a must..

we dont have AFPR's for our cars, the fuel system is not a return-line-type.

I'm new as far as posting, but I'll take a stab at this.

With those 5 mods listed with ORY and God's willing maybe 380's rwhp. Without pullies / TB and tuning, I cant see it being any higher than that IMO.

With the above mods, but stock headers 390rwhp is out of the question. At best around 360, if you were lucky.

Supposedly there was a car that hit 415rwhp
with all boltons and a MMS 229 Cam.

With the 224 cam Its going to be hard enough to hit the 400rwhp barrier with all the boltons.

With an LS1EDIT session it JUST might be possible to get the 410rwhp barrier...

A guy on this board made 394 with a T1 grots pully LS6 intake caatback open cutout 373s I think thats it. Car is a 00Z28.

Yeah, he sounds like a fountain of knowledge. He listed 2 mods that he can't even do! (Already has ls6 intake and there's no AFPR for LS1s).

There have been several posts in the last year about cam'd LS1s reaching into the low 400rwhp range with NO head work(except springs for the cam lift requirement). The TR 224 cam is a very good cam and it is proven to reach into the 400rwhp range easily. With the right combo of intake, tuning and exhaust mods, I wouldn't bet against it.

Yes. Less rolling resistance I believe.

WS6Modder

Here's my setup:

TR 224/112LSA cam with associated upgraded valvetrain
stock heads
ASP crank pulley
FLP's with ORP's on
Cut-Out
LS6 intake
TR custom tune
PACE LS6 descreened MAF tuned with MAFT
DF Lid
ATR cat-back

Thats about it power-mod wise...lots of suspension as well...but stock driveshaft and at the time of the dyno (381/376), stock 10 bolt with 3.42's.

Ive seen the 398 with dyno tricks...thats as high as I have seen. Not saying you couldnt get over 400...but not without tricks galore IMO.

I say let this guy believe what he wants...he's the one that will be disappointed in the end. Quit your battle with him...why argue with a moron?

Keep in mind this is without headers.

id like to see this AFPR. Thats Adjustable Fuel Pressure Regulator. Yes, you can replace the stock regulator or add one in-line, but i see NO benifit for NA purposes.

Guess I should have clarified. I was referring to this point:

Sears

I did 398rwhp with stock heads and no custom tuning, stock rear/gears. My friend did 402rwhp with stock heads and the 224 thunder cam. He has the same mods as me in his SS, but no AL flywheel, no CF driveshaft, no custom tuning. So I say it is possible to reach 410rwhp with all the bolt ons, ls1 edit programming and the 224 Thunder cam. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I think a lot of it has to do with the car being "strong" from the factory. Some cars just dyno better then others mod for mod. And also how well tuned it is. He better hope he got a ringer. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Don't get to caught up on dyno numbers, it's all about what it runs at the track.

Just to hop in, My dyno is here Dyno
I think its very possible to see the numbers im looking for considering I put down those numbers with only a lid and a K&N. There was some detonation above 4600 rpm on both of the runs which leads me to believe that there is some more power I could have tapped. 1/4 mile time so far is 13.1@109 on streets using a cutout, FTRA (removed), AFPR, lid and un-tuned MAF Translator. Im going to try and get the car back into the dyno soon before it heats up and get a run with the MAFT since its somewhat tuned now (no codes anymore and feels stronger, consistently set lean codes before).... as far as track times its posting better numbers as far as bolt on LS1s go out here so I believe the Thunder 224 cam with the full valvetrain upgrade can post at least close to the 390 neighborhood and if I invest in headers at the same time I dont see why I wont hit 400. The stock manifolds on the 01+ LS1s (Z06 Manifolds) flow pretty close to that of shorty headers so just throwing on those wouldnt help me much... however I may get a set of TTS headers to accompany the cam. And even if I dont hit the predicted numbers Im sure I will be more than satisfied since there is a Z28 with the same cam out here thats tearing up all the street cars!

Edit - before verbs complains some more YES I do have a full suspension, but a full suspension hinders trap speed, not help it, so why my ET may benifit from it I bet I would see a higher trap without the suspension setup since changing the pinion angle can be a hit and miss and result in absorbing more power if set for traction instead of power... I have the suspension set up for launching and I see consistent 2.0s every launch while trapping 109+ every time through.

335+ RWHP and 109+mph trap speeds sounds like a dyno queen to me, unless your car weighs over 3800lbs with U in it.
