Default Header wrap... any real benefit ???

header wrap... any real benefit ? I have a 800 hp Turbo'd street car that makes full boost at 4k rpm's... ( with a pte-76 un wraped hot parts except a turbo blanket... I want it to spool FASTER.. here's my real question... would wrapping the hot parts make full boost sooner ??? and if so... would the extra heat cause my IAT to rise effecting my intercooler's ability to cool the incoming air ??? like more turbo heat, more intake heat ?????? Is it worth it

I doubt theres much of a temperature drop from headers to turbo that would affect spool time that much. The main reason people wrap is because it cuts down the heat in the engine bay tremendously. Since that is where most of us are pulling our air from, it will help IATs.

no, it is a front mount... it's an actual ptk kit ( lt1 ) with like shorty headers... idk if in the tuning ( timing ) or what not. I love the "number" of horsepower I have but I wish I had more usable power... anything to get it to spool sooner I would be willing to try lol... I just thought a 76mm turbo would kick in better for street driving, I know it's not really all that big of a turbo

Get more cubes? Theres not really anything you can do to get spool time down. Im at full spool at about 3500 with a t70.

oh... this is a 381 cubed motor... so I guess it comes with the turbo territory...

I say wrap it. Worst case scenario you cut down on engine bay heat which is nice. I think it will spool faster with wrap. The more heat you keep in, the better it works.

You'll get much better spool with more timing and either a leaner or richer mixture at the 3500-4000 rpm area. Leaner mixture if you don't have a large cam in there and by leaner, no more than 13 to 1 AFR at low boost levels...As far as timing, I have seen guys run 30+ in the low boost area to help spool...This will make a large difference in spool if you have not already done this...I have not seen any spool difference when I have wrapped hotside...

I guess I am a bit of the black sheep in this debate. I wrapped my hotside and not only did it cut down on underhood temps but it reduced the underhood exhaust noise you typically get when you go from manifolds to headers...for me it did help with turbo spooling by a noticeable amount.
I have my timing pretty low during spool up, full boost by 2800rpms.

Full boost at 4k RPM is pretty much "ideal" for a V-8 that's driven on the street. Wrapping the hotside really will do little to change this. I personally don't understand why some want insta-spool. The car will be faster on the street if it spools a little later in the game. Traction is a good thing... Really unless you can upgrade to a billet wheel or ball bearing center section, there is little you can do if you keep your current setup. Timing is also an option, but don't expect any huge reductions in spool time from any of this stuff.

Are you running an auto or 6spd?

my old t63 precision spooled at a little over 1500rpm, it was fun, but choked the motor at 3900rpm and gas millage was pretty shitty

it is a 6 speed at the moment... might go w/ th400 someday though... I love the turbo don't get me wrong... but I miss the neck snapping torque of my old set up... now it feels alot slower up until boost but when I'm in boost it's a different world. maybe because I lowered the compression a tad I think... it's about 8.8 now... But I really shouldn't be complaining It's a good set up and I should just shut up and enjoy it

Yeah a TH400 will make that a totally different car. Throw a 2 step in that bitch, it will change your life! Dont get me wrong, I loved my six speed, but there is a point where they just don't cut it anymore.

What size is the hot side? My T6 flanged .96ar hotside 74mm spooled at 3800rpm on a log style manifold on my old 383LT1 (all wrapped also)

Also I do have a TH400 with a 3600 stall....on a 8psi spring I would see about 5-6psi by 4-4100rpm.

Id say wrap it. All of my stuff is wrapped. The more heat you can keep in the pipe and out of the engine bay, the better. Hot air is expansive. In theory it will have a greater volume and spool the turbo faster. Just my $.02.....4k rpms isnt that bad though. If you are gonna get on it just downshift? lol. sounds like a sweet ride!

I'm gonna wrap that bitch then... :-) if I can lower spool times by 200 rpm's it'll be worth it to me... when money allows i'll jump on a th400 hehehe for some dragstrip fun
