does anyone have any experience with a waste gated exhaust manifold im currently building my truck for drag racing switched the 5 speed out and built a full billet 47rh in it and just got it in I have just installed a hamilton cam new valve springs and and ported the head and fire ringed it also put on the dragon fire vp I want to be able to have a a very fast lighting charger with big end capabilities so im thinking of using a tighter exhaust housing with a waste gated manifold with a 71mm compressor wheel guess my main question has anyone tried this and if so did you have to weld the the wastegate fitting to the manifold or can you buy one done and has anybody tried anything like this with any luck??
 
Works good, if you know what you're doing you can weld them in, or buy a flange cut from steel to bolt to the manifold to make the welding easier...however a 71mm isn't going to light too fast, so make sure you understand the spoolup characteristics of a big charger ;) ;)

contact chris from E.D. he has the sweet wastegate adapter flanges( i love mine) cheap too! also hear they are pretty sharp on turbos with more than off the shelf type stuff.

ED's gate plates and tubing aren't very expensive. That's the way i'd go if it were me may save you some head akes down the road.

A big stall with that charger is your friend:). Your cam and head work should help get it going though.
 
Chris and Glenn are easy to do bisness with also!!!! They get my vote!

thanks guys I def appreciate it lol its been along time in the making to save the money just want it right the first time I will give these people a call and see what they have to say I may be better off in the 66mm range but we will see what they say my stall is only good for 2,200 lol with vp I dont have many rpms left after that but I think it will manage
 
If you can only stall to 2200, I'd go with a 66 or 68 vs a 71...it takes 22-2300 rpm to light most 71's IMHO,

even with a 24 valve with a cam and head work? For reference 2100 was where my 468 would take off. Being rpm limited is a case for a smaller charger though for sure!
