Dyno runs of Port and Poilsh Head TIBURON!!!!!!! - Hyundai Performance Forums

2 UNIQ · 02-16-2003, 02:00 AM

I digged up an OLD Dyno run which i did three years ago when my car was an AUTO and Port and Polished my head as well as a valve job.A radius cut was done to the valves which flows and works better than a 3 or 5 angle job.I also bored my Intake manifold when i installed the bigger Shark Racing 58mm TB.The shop did the head and IM for me
What you will see in the Dyno are 3 runs in Total.One of them is my Baseline run which was at 112WHP.Keep in mind my car was an AUTO and all i had was a CAI,4-2-1 Headers and 2.25 inch exhaust.My car stock does 100WHP with my 1.8L motor.A stock Auto 2.0L Tiburon will do 104-105WHP as Batlord did this for us a while ago.
I gained excatly 10WHP and 7.4 Pounds of Torque at the wheels from Head work and the IM job.I had NO S-AFC at the time and if my car was a 5 speed or had a S-AFC my gains would of been more.
Anyways here is the link to my Dyno run

As you can see Just from the Head work alone is good to about 7WHP and the 58mm TB is good to about 2-3WHP.If your car is a 5 Speed or if i had a S-AFC the gains would of been Higher

EDIT. Use this Link. You can actually READ the dyno...

Looks nice. That's reasonable gains on a street port, especially with a TB that small. (Where I'm from we start at 58 and work our way up to 70mm.) It's too bad you don't have some flow charts.

I'll keep my opinions on the radius cut to myself. :rambo:

How much does a port and polish typically cost?

Somewhere under $1500.

Wow, that is incredibly expensive for only a 7 hp gain.:depressed:

Note that I said under $1500. The performance gains vary widely based on the quality of the P&P job.
