I'll be hitting up south mountain all the way to the radio towers in an hour. Hopefully not a lot of people there

I am so tired... and I have to write two papers... I just want to go to sleep I was passing out on the way home from doing a side job. Just driving down the road and suddenly I decided to drive by Brail... yeah... not good but last night sure was fun!

What kind of gains have people seen with a header + tune?

As I recall from the dyno day, full exhausts with a tune were making around 180hp at the wheels, stock being between 140 and 160 on this particular dyno. so give or take around 20hp...not sure about torque.

The jdl header and full exhaust with intake and e85 tune had 186 on the maha dyno. which is about 20% less then a dynojet from what im told. A full agency power header/exhaust and intake i believe made 168.

I did 171 ish with airade, e85, test pipe and homeade magna flow exhaust.

I think the stock auto we ran was 145.

Did we ever post all the results

Hey guys, I just have a quick question. Maybe it was already answered in a different post.
But is it possible to rerout the DRL as fogs, so when my main head lights aren't on, that's all you see?

I should be picking up my BRZ tomorrow. Any upcoming autocrosses or track days near phoenix?

In my view there are other factors to consider with respect to a choosing a header besides which one makes the most HP on a dyno. The ones that make the most HP may be weaker in the mid range and do less to cure the torque dip. Everyone has to make up their mind on what their priorities are. If you are drag racing your car or spend a lot of time on a road course with long straights then getting one with the best top end numbers might be the way to go. For me personally, I rarely get to drive my car flat out and I spend little time on the street at red line where the top end HP will make a much difference. I will pick one that cures the torque dip and gives the best mid-range increase so I get that nice "Jerk me out of the corner feeling."
For top end the experts say that a 4 into 1 design is the way to go. For best torque and mid-range a 4 into 2 into 1 is the way to go. Like a lot of things, it comes down to personal preference.

Thanks for that! I could careless about top end but definitely want that TQ dip gone! 4-2-1 does that still mean Equal length?

I wouldn't assume that all 4 into 2 into are equal length. That could vary from one manufacturer to another.

Just spotted a raven or asphalt fr-s south on Palo Verde with temp tag anybody here?
