can any one tell me the horse power and tork gain with polishing porting heads and intake?

 

5-8 WHP

 

I can see that gain in a V8, but that much of a gain in a V6 is not likely.

 

If you make the ports too big or port the wrong areas of the intake ports or combustion-chamber.. you will lose power if you are naturally aspirated. You almost always gain power if you use NOS or Turbo. Porting the Honda/Acura heads is a precision-job... every Tom, Dick and Harry can't do it.

I'd say a GOOD port-job will gain you about 15hp at the wheels give you have intake, exhaust, header and appropriate fuel-management. This port-job will cost you at least $2000.

 

Mike the moderator can chime in...

 

Don't waste your $$ unless you're going the FI route.

 

I second that...

 

FI route?

 

Forced Induction A.K.A Supercharging... turbocharging...

 

technically that should read e.g., supercharing/turbocharging
free english lesson for the day.

you can also include n2o in that as well.

 

If suck real hard...thats fi too...

 

supercharing ??? Is that the extra crispy version of superCHARGING...

 

touche :P

 

it two late for that i just finised it results were bad i will have pictures and dyno sheets soon 10.8 hp 6.5 torqe.

huh? elaborate please

 

Those #s for P&Ping the intake manifold and heads? ouch!

 

Holly crap, did you get it professionally done?!?! How could this be?? A professional Port and polish should increase airflow, which in terms give you a few more ponies.. shouldn't be a decrease.

 

i think he's saying he only got a small increase and hoped for much more

 

howd he get it done so quickly? did he just post it yesterday or the day before?

 

Okay.. well in that case, he should be happy with what he got, because supposely our cars already has somewhat of a port and polish over the none TypeS cars, so to squeeze another 10hp is quite good for a non-Force Induced car.

 

no way. here's your stock intake manifold






EXTRUDE HONED INTAKE MANIFOLD

 

we need pics and the dyno!

 

how much E&H would gain in HP 3-6 WHP!! for $600....

 

but take a forced induced car, and extrude hone the manifold and your gains will be significant compared to the 3-6whp. And you guys all complain that for 600$ you are only getting 3-6whp. Which sucks, but think, viper guys are buying headers for close to 2K and getting about the same gains. However all these things will work good in the long run when you have a full package together.

 

OK I just spoke with John on the phone. He increased hp and torque throughout the whole range. His max hp was 242, and a little over 200 pounds of torque. In certain places he had a bigger increase in hp. A lot of tuning was done with his v-afc and air/fuel controller. Although it doesnt sound like much of a gain, I personally belive this should be enough to get John into the 13s. He will post the dynos as soon as he has a chance.

i am old and need help down loading pictures and dyno sheets when i get help you guys will see .

 

Mike, I know what you're saying.. I was just pointing out the simple fact that Acura is using it as a selling point for the TypeS models. I would love to find out more from johntypes on where did he get this p&p done at, I'm very interested.

 

email them to me @ mikegcls@yahoo.com

 

Woa

 

Don't do it, it's not worth the $$$'s

 

when are you going to the track, john?

 

AS soon as the snow melts.I will post
