Doug Thorley Headers!

Thanks again. Yeah, low end loss is my biggest concern to. I don't tow, but my daily driving routine doesn't get me above 3K hardly ever. I miss the simple programer and timing advances of the old days.....

OK, back on topic! 4 cylinder header info.

 

08pretaco, thats for the 2.7, correct? (assuming so, looking at the #s).

And is that against the DT short?

 

there is only one DT header for the 2.7, there arent long and short options for us.

and Lurkin:
I totally understand where you are coming from which is why I havent wasted my money on a CAI. those, if they help, only help at really high RPM's. I never get above 2.5k on my tach (unless in the desert) I will promise you this though, you get some headers (i have DT) you will not be dissapointed the low end gains were/are amazing!

 

Agree on the CAI and on catbacks. A bit at the top end, so basically sound only for an NA.... As for the header comment, are you referring to DTLTs? If so, I just can't seem to get a majority input one way or the other as far as LTs and low-end loss. Some say yes, others say no.

 

That is a nice chart. Who made that using Excel?

Anyone have the actual dyno chart printed from the dyno?

Hey i just post whats there. Their dyno of yours IIRC matches up perfectly. Regardless Gadget, I love my DT and will continue running them and I DO recommend DT header for the 2tr-fe to anyone who asks and tell them you guys are the peps to deal with

i did email them regarding the real chart but they said that was all they had.

 

Here is the DT header dyno for the 2.7 (actual Dyno).



G,

Could it be possible they are making their dyno off a manual transmission? Cause I see that DT make theirs off a Auto with would bring down power from tranny loses.
