I like the small cam I have now, and don't think a 100rw shot (next year) really warrants a nitrous cam. But what else would help when looking for some extra HP? According to an chart in the exhaust forum it seems my exhaust system is already at the limits of my 370rwhp. I'm running Pacesetter LT headers and Y-pipe (catless) to a 3'' Edelbrock pipe and muffler. The car has a cut-out under the passenger seat for track use.
I'm thing of having a custom y-pipe made that has a better merge at the y with a 3 1/2" exit. From there, it would be 3 1/2" pipe to the same size cutout. The over the axle part can stay the same for street use.
Do you guys feel this will add some HP? Down the road I'd like to build something NA that would be in the 425rwhp range. If I get the chance to do this, would it help the nitrous if I had some more porting done on the exhaust ports and run bigger exhaust valves? Right now the heads have 1.57s. Sorry this wound up being such a long post, Rick.

 

Don't bother with the exhaust. If it doesn't go as quick as you want, add more nitrous.

Thanks Rich, now if you could just give my stock (30K) shortblock a pep talk, I would appreciate it.

 

Come on 30k mile stock short block you can do it, this all stock 100k+ miler went 11.00s through the iron manifolds and "Y" pipe....yeeeha 139k now...ya don't need the cam or pipes.

 

Nice, maybe I'll be close to that next year.

 

How much spray are you using? I'm looking at running around that time with a budget and would love to know how you did it!

 

20+ bottles here with 140k miles on a 150 shot

 

Is your engine completely stock? What time's do you run? I'm really thinking about running a 150 shot on a near stock LT1 and would like to know what time I could expect.

 

he has traction issues...but it has mid 11's on it
