Chance off 400rwhp?
I am installing a MS3 on 113lsa, supporting mods are UD pulley, LG streets w/o cats, corsa exhaust, and stinger intake. Is it possible to make it to the 400hp mark with out the LS6 intake? I am having a hard time getting one to me be the time I need it before the dyno time. I read a few testamonies(sp?) when I searched and they varry quite a bit. Also I saw some intake comparison charts over on LS1 tech and it looks like you only get 10hp max over the LS1 intake with the LS6. Anyway what do you guys think is it possible or should I really try to be pushing hard for an intake? Thanks, Patrick

I Dyno 345 RWHP and 346 RWTQ on my 6 Speed, but I have 4.10's so it pulls like I have 420 RWTQ...

I have an M6...
a 228R (much smaller cam from TSP) LS6 intake, ud pulley, springs, harden push rods, LS6 ported oil pump, no cats, TSP LT's, factory Hpipe, corsa exhaust, ebay CAI and i think that sums it up..
Tuned i put down 386 without the ud pulley which has claims of 10rwhp gain ( so i assume i'm right around 390-395)... I've seen the MS3 (well a very similar cam) put down well over 400 untuned with all the supporting mods on an SS.
I would say if you have a stick and you don't put that down after a tune,go find a corner and cry...

Yes I am staying with stock heads. I have a MN6 with stock gears. Well lets hope I dont have to cry then. So the LS6 is really only 5-10hp even with the addition of a cam? So I guess it sounds like I should be alset then with out the new intake. Thanks guys you saved about
$350 and a huge headache trying to get one in time!

well if you look at my sig and figure the difference between parts I would guess you will make around 400. I cant see my heads being worth more than 50, so if you subtract 50 then you are at 408 with stock heads another 10 for intake puts you at 398.

God I hope I dont only get 370 if I do will not be going to that tuner ever again. I am planing on making 380-400 wich should be just about perfect for me. And if I get to used to it I may eventually go with some 3.90's. Thanks for the input fellas.

HP must be hard to make with an auto. With my heads/cam and all associated bolt-ons I just dynoed at 385 RWHP and 375 RWTQ. Of course it was 95 degrees out but boy HP figures are not easy to come by.

With heads/cams/LTs most LS1 should be at or over 400 RWHP.

I don't know my Cam specs, sorry, it's a G5X2, stock C5 heads/rear end, LS6 intake, Stinger, LG LT's w/cats, upgraded wires, other misc I cannot recall at the moment, and my numbers were 400/386 - I'd say you will not get there without the intake depending on the X2 cam specs, perhaps someone else will know.
The car was dyno'd at LG in January. I don't think I'd do anything different, the car is incredible to drive and still 32 MPG (on cruise control, don't think I ever get those numbers over here....!!) I think heads were yeah about 50 HP more and about 3-4K more $, I figured 10 grand was enough for the car and left it at that!

Speaking of revs..... I read about the fact the LS motors or at least LS1 has weak rod bolts and that limits us on our red line. What is considered to be a safe limit among the cam guys? I was thinking of having mine set to 6600 to be safe from what I have read. Although my cam choice of the MS3 can make more power higher up I dont want to risk it. Does that sound about right?

I would think it is your springs that you have to worry about. What springs do you plan on running? I have 921 comp springs and redline is 6800.

the PRC's are good, same thing as the patriots. good up to .650 lift, your cam is a 237/242 .603/.609.... your springs are fine.
far as power wise.... you should def. see close to 400. thats a pretty big cam.
there are so many variables as to why you see differences in similar setups. different heads, intake manifolds, etc will have an effect. but the tuner/tune, dyno, weather, etc. will also have an effect.
