Stage 2 Cylinder Head Kit Information

 

hmm not too bad, depending on the size of my bonus check I may pick one up. Already have a spare head, so that's no problem for me.

 

what kind of redline could we have with this setup. do you have any dyno results

 

good lookin guys.

the 10-13% increase is over the stock head flow numbers correct?

so about 60-78 extra CFM(thats 10-13% of 600CFM)

sound correct? any flow sheets for this head?

 

Redline for our springs are 7500RPM. For results on the Stage 2 head kit, read a little further down...

Close approximation 06black and in some cases you are correct. The percentage increase we list is HP. It's not feasible to list a finite horse power gain as our head kits will react differently on a vehicle with cams, with intake, with exhaust respectively. Hence a percentage increase is listed as a guideline as the increase of power in relation to your current HP standings.

We've got flow sheets for our Stage 3 head handy, would you like to see those?

 

ohhh, ok!

i figured it would be flow numbers based of a "base case" scenario car.

my mistake, as for the stge3 head results, i'm ALWAYS up for some flow numbers!

I might() have some stuff i'm gonna send to Rod next week, make sure he sends it to ya.

also, after some lookin around i would say that if any thing your power gain percentages may be a bit low, from the numbers i've seen from other sources on your big money head, its well over the max of 19% gain you say it to have.

but ****, overachieving is never a bad thing huh!

with the stg2 head, on my motor, with it being naturally more efficient (turbo vs blower, drag,ect,ect) and capable of begin supplied with a larger airflow i can see a larger then 13% gain. but this would be more specific mine and pauls application.

 

Right, its better to post a reduction and to use a percentage gain in a case-by-case basis. Albeit it is entirely possible to achieve a higher percentage gain and this has been done by other customers with this head package, albeit we are conservative in the % gain.

What "might" you have coming our way?

 

some pics and tid-bits of a few things, i find it fun to work on and with, i think you guys and rod will as well.

how bout' them flow sheets?

 

yeah as I see it, should make some nice gains coupled with a decent set of cams. What's the turn around time on these heads?

 

Pretty decent. With all thats going on in the shop at the moment, we can do 2 weeks.

This is Rod's head... Stage 2 is great.. but not this great.

 

hot air flow test FTW!!!

have you guys ever done a stock head just for some comparison.

i have 1 stock flow sheet but i'm not sure what i think about its accuracy.

i'm all for head porting, and i have some quite specific flow goals, and i know the exhaust side will be the limitation, however with that stg3 head flow sheet i see it can be done and beaten by you guys.

basically i require a minimum of 800CFM (total) head flow for my power goals plus a margin of "safety"

so aprox 200cfm per cylinder. the intake side should require minimal work to hit that number, but with out a stock sheet i'll never know how far off it is, my sheet puts its dam close to that, how ever the exhaust side, the side that truly matters will take some work.

so basically, does your stage2 head boast that flow rate?

let me know what you think.

 

man that scan was terrible, I can't believe you could read it.

and yes, hot is the only way to go for accuracy.

well, your flow rate is dictated by port size, contour, valve obstruction/lift/duration and the short radius of the runner to name a few variables... Pending the camshaft that you couple to our stage 2 head kit is not overly aggressive in duration and similar to stock, you'll have ample CFM to supply your needs of 200cfm / hole.

 

I've got cam specs that i snagged from a location i frequent between 9am and 5pm every day

I've PMd them to you, i'd like your thoughts on "overly aggressive" and the convo can become much more open that way.

thanks for all the information to date, vary nice to run across this.

 

no prob.

 

bump for this, this head will support more power then dam near any one is looking to push!

get'em while there cheep!

 

*bump*

 

just waiting on my bonus check.... damn shoulda had it this week already

 

a lot of interest on this one from our dealers... surprisingly, mostly the LE5 head!
