100 shot DP NOS setup soon to be used as soon as I finish breakin it in

154.1 hp and 136.1 ft/lbs of torque. What ya guys think, i was hoping for a little bit higher and i thought my peak hp would have been closer to 7500 rather than 6200. Do u think i need some headwork or a better IM, or should i be happy with that rpm range. Dont know if i wanna go higher than that rpm with nitrous and spin a rod bearing, rather take it safe, let me know what ya guys think

 

if you get a skunk2/blox type intake manifold it will bring your peak power higher up for sure.......

the LS head need some work also......you can make quite a bit more power if you have the head ported.

also make sure you have those cam dyno tuned with cam gears. the 404's right out of the box aren't to impressive until you change the cam timing around.

 

You need a port and polish and intake manifold., also the cams are meant to go to 8200. You should be able rev to 8200 with your internals.

 

What's kiling you is the stock IM and the stock head, get a p&p head, IM and some cam gears and you'll be A LOT happier.

What do you mean by breaking in your motor? Your post says Uberdata tuned. By that do you mean you "dyno tuned" it by using Uberdata set up? Or, did you just use uber data base maps.

A link i ran across on "how to break in a engine"

according to this you shouldnt even be driving it until you tuned it.

 

I used an uber base map, I have a plxm300 and datalogged it through uber to get about 12.5 - 13 at WOT. I then took it to get dynoed on a dynapack and have my cams dialed in. They said that i got the most with +2 +2 on the cams. I think the head and IM are killin me too. I also have a 2 inch crush bent exhaust thats also killin me. I found a 2.5 in mandrel bent one that im pickin up this weekend and putin a obx twin loop muffler. I think im gonna pick up a bare ls head and have it ported and match it with a blox IM so Ill have almost no downtime when I install it. Who does good headwork for a decent price around here?

 

you need vtec simple as that
