My inlet is already opened up to a 102... but no need to drill and tap anything.

I also am only running a ported LS2 TB as Pat mentioned.

 

Where I was going is if you do have a pressure drop behind the TB, your only option is to go to a bigger TB.

How much boost are you loosing?

 

Yea I followed you. I am going from 205KPA in first gear at 4400 RPM to 196 at 6000. I can only assume it will get worse with more revs.

 

I hope you get the stuff figured out. Cause if you go to the track tomorrow you'll see me there, er more like like I'll get to see you there

 

goodluck to both of you. I heard you race for free if you wear a halloween costume

 

I'll be there!! I don't expect much tonight though... I am definitely out-flowing my intake and I have a suspicion its the elbow on the TB. Boost starts falling off early and yesterday I hit 188KPA by about 6150 RPM. I wouldn't be surprised if this thing is done making more HP at 5250... a shame considering I built and planned it to rev to 6500. Now I'm not saying HP is falling off by 5250, but I can say with confidence that its not making any more power beyond that.

 

What's the elbow made of?? are you sucking the elbow in??

if a 4 banger can do it....

 

If you got the room you could make a 4" pvc race intake like me to use at the track, its better than running no intake and sucking the hot radiator air in

 

I need to use my intake tube... thats where my meth is tapped into.

And its silicon. Entirely possible that it collapses a little.

 

Go get some **** at Home Depot to fab something for the track, keep the elbow solid. All 5"
