Default My first dyno

Well I finally got a chance to dyno my isf, was hoping for a higher number but oh well.
This run was with a borla catback,joez intake,toms drop in

All runs were done in 6th gear, except for the last which was done in 5th.

Don't worry about the dyno just hit the track. Numbers look a tad low but every dyno is different and looks like it was hot and humid.

Actually his numbers are not out of line with what has been posted before. Dyno runs should be run in 6th as that is the one to one ratio gear.

Seems a bit low and those runs weren't even in SAE 5 format...

Yeah I'm just hoping it was due to the humidity. Ill take another shot at it when the humidity goes down.

All dynos are different dont use a Dyno as a end all of end all measurements. A dyno is good for doing a base line measurement and when you do a mod such as exhaust or headers you can go back and measure the gains in performance off your base run. Dyno pulls are really pointless in my opinion only useful in measuring gains in mods

Was planning on going with headers soon, therefore I wanted to see the gains. However was hoping my numbers would've been higher. I am planning on going to the drag strip soon for the first time ever as well, hopefully I can break into the high 12s.

If you look at my graphic (Post #3 above) you'll see it's about 30 to 35 BHP.

I'm attaching a real old Dyno I did, just after my header install. You'll see about a 30 BHP increase with PPE headers vs stock manifolds.
