400 rwhp cam only

**V8MUSCLE** · 03-02-2010, 06:50 PM

Virginia speed, one of the better ls1 shops told me they would be able to easily get me to 400 rwhp with just a cam. i can understand getting 20 or 30 hp out of a cam, but 70-80+, cam only?

**Z28boy2000** · 03-02-2010, 07:31 PM

id say 400 is reachable with a full exhaust and cam relatively easily, it would have to be a big cam....IMO MS3 or such and one hell of a tune

Torquer2 cam, headers, ory, dyno tune= 400rwhp or damn close on a m6 car.

you will definitely need full bolt ons. a fast 92/92 combo should seal the deal if you land just under 400 with the ls6 intake. fast gives a good increase when you change internals, but stock bottom end it isnt a big jump unless you are on a number hunt.

wait til the 10 bolt is replaced with a quality piece. the weight will lower that number.

Definitely can. I hit 398 with my little 224/230 comp with mods in sig. Im lookin too add some heads and ported fast 92/92 and have Ed from VaSpeed tune it this april. Shootin for 440rwhp

**01ws6er** · 03-03-2010, 06:25 AM

Why so much focus on only hp? Get that torque up there too with a nice flat curve so the power is available wherever, whenever.

15 degree heads are wonderfull. Which is why these motors respond so well to a simple camshaft upgrade.

**marksls1ta** · 03-03-2010, 07:39 AM

yeah it is doable on a good tune with cam and supporting mods. Virgina Speed is a great shop also.

thanks,
Mark

which happens to be why trick flow heads are so effective. they offer 13.5 degree heads. i don't know if it is just their top of the line heads or all of their lsx heads.

**Z28Thunder** · 03-03-2010, 12:51 PM

Cam,headers and stall here, and 400 + on HP. But not really a dyno person here. All that matters is track times for me.

Ya that's an advantage for Trickflow. LS7 heads are even better at 12 degrees.

**jerri311** · 03-04-2010, 11:26 AM

400rwhp here with cam, headers and ory.

**Intrepidman** · 03-11-2010, 06:17 AM

I've been wondering one thing about these cam only #'s. How do they drive, and what are thier characteristics?

If you put in a big cam that gets you in the range of 400+hp that motor is surely going to feel a lot different than one with a much milder cam and head package making 420+hp ... or am I totally wrong?

And Performance Induction makes 11* heads

If Shawn says he can get ya 400 bank on it

I am hoping to join the 400+ rwhp club here shortly (when I get a tune). My cam is a 230/230 .612/.592 111+2 on a mail order tune. People kept saying that thing will have shitty street manners, blah blah.. Honestly, if u think this cam has bad street manners you should keep your car stock. Just my .02

"Manners" or "Driveability" are a bit subjective, what one person thinks is fine could be untolerable to someone else...but when I mentioned how a big cam 400+hp motor might feel different than a mild head/cam 400+hp motor I was thinking more along the lines of each build being fit to a different task or driving style. Just theory on my part, I haven't tried 2 such different motors, but wouldn't the hp/torque curves and other factors be very different between the two?

I didn't think dding my car with my 238/242 112 lsa cam and 3,800 stall was that bad either....just had to let it warm up alittle before you took off
