i dont think you would need anyof that if your going for 300-350 the rods are strong from what i read

 

hp tuners, 60lb injectors, and an extra heat exchanger are defnitely a requirement. Exhaust not so much, unless you are going for BIG power.

 

Why would we need an extra heat exchanger for a supercharger that is going to be pushing cooler air then our stock supercharger

 

cause it's still not cool enough.

 

no it doesn't have the cam sensor for the exaust cam...........i think, maybe i'm wrong

 

Then why a heat exchanger and not a meth kit you have to get a tune anyways tune the meth kit in and honestly i dont think you will need a h/e unless you go below a 2.9 pully on that becuase this is gunna push more air but cooler air so i dont see any need for something we dont need now on a 2.9 pully on a supercharger that is pushing more hot air then the tvs will with a 2.9

along with what Witt and TVS_SS are saying, if this swap requires a larger maf tube like it does for the turbo swap the low TPS MAF accuritsy(sp?) goes to **** and looses some repeatability, not the nicest thing to deal with when doing a maf tune.

another possible option that people might have to take into consideration is the cylinder sleeves.

this would only truly be needed by the people who port the heads. with the stock head limiting out at ~580CFM you physically cant flow the air needed to make 400whp, its just not there, regardless of what others may say or think, this is a fact.

so say you bump the head toward 850cfm range(putting you in area of 500+ whp) and you have the bottom end built like most do / will the one commonly over looked area is the cylinder sleeve that we owe so much of our stock horsepower ability to.

they say it needs to go rite at the 400whp area, i've seen them go a bit higher (463iirc) but once again, if you leave them stock at that power range your walking a fine line between "ok" and "i blew **** up"

so, for the high HP guys this might be another good thing to built on the list of parts to swap during your build.

 

its made for the ls4 tb, so that should be required... but stock tb might be able to handle it

 

most people are forgetting you are still limited by the same flaws of the m62.

 

CFM?

 

negative batman

 

I just compared the 1320 map to the 1200ax map today. I will say the 1320 is a bit more efficient and has a larger footprint for a bit more power output. However, the ouput volume on both seem to be correct in their size. The 1320 has a slight advantage as it is indeed a bit bigger. The 1200ax will be limited to it's 2.8" pulley whereas the 1320 will be limited to a 2.7" pulley. With that said, I'm really anxiuous to see what this badboy belts out.

 

so then what other things could possibly be a problem? This blower is supposed to run producing less heat and is able to run safely to a higher peak rpm than our current blower.(i think...) So besides how much power needs to be sacrificed to make it run, what else could be a downside?

You turbo guys never shut up! lol.

Anywho, About the "race" heads. There are two different ones available. One is a race ported L61 head, the other is GM Racing's Ported LSJ head. While the L61 head is available from GMPP dealers all over the country, you can only get the LSJ head from GM Racing Directly (www.gmtunersource.com).

 

im not turboed!

im still on a box stock m62

 

I'm talking about your arguement, not what you're personally running, lol. No worries.

 

go eat your cookies

 

cylinder sleeves assjocky.

 

Let's stay on topic here, eh?



bawawawaawawawawawa!

 

topics suck

 

**** your topic

 

I was browsing that site but didn't see where you can get more info on the gm racing ported lsj head?
