Buckeye1647545503 Posted July 7, 2005 Report Share Posted July 7, 2005 So I have heard that wraping the DP with header wrap is good for a few ponies. Is that true? how far down makes the best results? What wrap hols up the best? Is there a spary that does the same thing ? Quote Link to comment Share on other sites More sharing options...
Brandon Posted July 7, 2005 Report Share Posted July 7, 2005 It just keeps the heat it, which keeps the exhuast pressure more stable, with a small possibility of more horsepower. Quote Link to comment Share on other sites More sharing options...
Maro Posted July 7, 2005 Report Share Posted July 7, 2005 I've heard that wrapping the uppipe and headers will give more hp. Not sure about the downpipe though.... Quote Link to comment Share on other sites More sharing options...
dragknee66 Posted July 7, 2005 Report Share Posted July 7, 2005 Well the exhaust gas is still quite hot in the DP as well. Wrap a couple feet of it and youll get some good flow. Quote Link to comment Share on other sites More sharing options...
Nate1647545505 Posted July 7, 2005 Report Share Posted July 7, 2005 Doesn't really effect HP, more of spool time; I guess that does effect HP in end all. Fluid moves faster when it is hotter. Keep the thermal heat hot and inside, it should move faster throughout the system. Wraping cast iron can crack, wrapping an aluminum may cause it to rust. There is a spray you can use over the wrap to counter that, though. I chose to go coated. Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted July 8, 2005 Report Share Posted July 8, 2005 also keeps a little more heat out of your engine bay. Quote Link to comment Share on other sites More sharing options...

villision1647545496 Posted July 9, 2005 Report Share Posted July 9, 2005 Wrapping the "header" will decrease spool up time. Physics really, keeps heat in. Since a turbo is spooled up more by egt than actual pressure (catch 22 really), the heat decrease spool up time. Why else would a little 1.3 litre like a rotary spool up a hefty Greddy T-78 by 3300 rpm's. It is becuase the EGT's on a rotary are high 800/low 900 degree's Celsius. Imo, wrapping the downpipe will only decrease the underhood temps, therefore keeping the air SLIGHTLY denser. A customer of ours actually wanted us to "wrap" everything. So we did, on the bottom side of his LIM and UIM have "blankets" adhered to them. Ty Quote Link to comment Share on other sites More sharing options...
Orion Posted July 9, 2005 Report Share Posted July 9, 2005 problem with wrapping is that the further back you go, the more likly it is that youll catch it on something while driving and rip it up. color me experienced. Quote Link to comment Share on other sites More sharing options...
