Part#2 Dyno for my 09 ISF but now with Sikky Headers added. Graph Inside!
Guys finally made it back to the dyno today at Rage Tek here in South Florida Dynojet 248c and below are the results.
Car: 2009 ISF 47k all stock except Sikky Headers, and Borla Catback Exhaust
All graphs SAE & Smoothing 5
Dyno run #5 is from 2 months ago when i just did the runs with exhaust and toms filter after a 20 minute cool down and was my best pass before.
Runs 8&9 are the two new ones with just sikky headers and borla exhaust back to back.
Temperatures at time of dyno were high 90s low 100s inside the shop reading off the dyno. I got on did 3 back to back runs all 410-413rwhp without cool down car was behind me to get on so didn't get the 20 minute cool down like last time figured it would have gone over 420 for sure cooled down but these are off the street drove in made the passes. Car goes into Lexus to get returned to stock for trade in on Thursday, the exhaust is sold but the Headers will be up for sale soon.

That was average peak it was 25rwhp more on top end. But it was also different days and was 20degrees hotter today vs last. I would say if it was cool like last time it would have been another 8-10rwhp with a cool down like last time but ran back to back no cool down.

No wish I did have some but I was driving the car. It was a quick in and out wasn't going to even do it but some people on the board wanted to see what would happen after the last dyno and now with the headers before I got rid of the car.

Cool. I didn't know if you had high flow cats welded in for emissions or to keep the sound down some. How does it sound? Im now considering Borla catback for my first mod. I want to add headers in the future. I know the borla system sounds good with no headers. Does it have any rasp with headers?

Sikky headers avg. around 40 on stock exhaust system. And depending on the combo of intake and exhaust you have, it's another 20, for a total of about 60. This is the understood benchmark. Op's total of 410-413 is totally consistent on a dynojet with headers and exhaust.
The total gained without intake, again tells me that intakes are good as an aesthetic add-on to the engine bay, and there is nothing wrong with that.

As for the numbers like I said I believe 100% the car would do 420+ on the same dyno with proper cool down when it's not 100 degrees but just didn't happen to be the day for cool weather or cool down between runs. When i dynod before i got 370-375 on first 3 passes then 10-15 cool down an next two passes over 390hp. Also the temp was 87-88deg vs 100
Well she will be stock as of Thursday so we will never know.
