hey wuts up guys. I was at the ZdayZ tail of the dragon, which was amazing btw, and I won the raffle for a set of jet hot coated brand new crawford headers. I need to know before I install these if they will fit with either the turbonetics or aps single turbo kits. thx for any help that I can get.

 

I think you may want to just sell them, APS and TN both recommend using stock manifolds over aftermarket headers.

Nice prize though!

 

i know they both recommend stock manifolds..... but it feels like such a waste if I sell it. if it fits, id probably just install them and hope for the best ^_^

 

sell it and buy some other mods

 

Sell them..

 

stay NA or sell them... The money you get from selling them will be worth more than any gain you may or may not get from using them with those kits.

 

Just sell them if you are going single. They are also Jethot coated so you could easily get $1000 for them.

 

DONT SELL THEM. I am using crawford headers on my turbonetics stage 2 kit producing over 600whp, they are a solid mod. When I was with the stock tn kit I made 450whp @ 9psi with those headers most power for that kit. Just a little downpipe mod required.

 

Curious as Ive never seen you post this. You had to run an agressive tune to achieve 450whp @ 9psi on the TN kit. What was your timing at redline?

 

The Tune to achieve that map wasn't agressive, we went to 7100 rpms and through in a little more fuel, timing was right on at redline but the power curve dropped along 6800 somthing rpms, I dont know the exacts my tuner does but it was along those lines.

My car was perfectly healthy with that map, a bad injector caused a minor problem, but was easly fixable. Just wanted more power and went with the build.

 

I say throw them in. It's been proven time and again that better organized exhuast pulses spool turbos better, and clear the turbine with less turbulence which leads to higher enthlapy exhuast flow(had extra power and spool time yo.). The only downside to the SS manis I could see vs the cast stockers is cracking, but the coating should take care of that.

 

Didnt you use a dynopack to get those numbers? Not trashing your numbers, but dynopacks read high.

 

The headers aside from one person have never been tested for fitment but so far I haven't seen a set of headers that made any extra power over the stock ones with either ST kit. In fact all I've seen them do is lower the boost threshold

 

+1^^ I don't see any after market headers made extra power with the TN kit except for D350Z10(Crawford). I got Stillen headers in with the TN kit and no extra power were made and spool time is longer.

 

I know your pretty cool with your tuner and I know you use your UTEC-do a log and tell us what your timing looks like Im curious. "Timing was right on at redline" <----that didnt really tell me much-are you saying your using the TN flash timing map?

 

To my knowlege he never used the Turbonetics reflash when he installed his kit...

 

aftermarket headers are not recommended for the APS single turbo setup - had mine removed and put on the OEMs at install. the labor cost for installing headers would be several hundred alone - most places take about 6-10 hours to install headers.

 

Does this have a similar effect w/ superchargers? Or only turbochargers?

 

I never had the reflash with the utec tune, I am going in for another tune this week sometime and will log it and print it off, From experience and performance I can tell you first hand it is a good soild mod, the spool time is nothing it was like 200 rpms more so thats not even an excuse, I am just saying if you want stand out power go for it.

 

I think I recall that you had to have a custom downpipe made to clear the crawfords. Is that correct?
