This Thread Is So You Can Post All Tricks That You Can Do To A 2nd Gen Non Turbo To Gain Hp.

Anything Will Go Here. Stay In The Subject.

 

I Have Found The Ported And Polished Throttle Body To Be The Best Mod I Have Done. I Took Off The First Set Of Butterflies All The Vacuums And Now The Car Will Not Limit At Any Rpm. BUT IT DOES RUN OUT OF FUEL ONCE IT REACHES ABOUT 11000 RPM MY THIRD GEAR GOES FOR EVER.

 

Well Iguess He's Not Talking About A Stock Port Engine Ehh?

 

He is talking about a stock ported engine.He just ported out the throttle body. Do some intake port work and it will get better.

This goes for any car,thew first best mod you can do,I would have to say is exhast,or intake.. Changing the exhast to a more free flow set up will help the engine breath alot more.

I dont think the powerband for the 6 ports are still strong up in the 11k rpm.
I want to see some dyno charts.Not sure on the 6 ports but 12A stock ports the power band dies out about 9ish and no need for any more.

 

S4 6port starts dropping off around 6800 rpm. You can feel it.

Or maybe that's where the stock air box maxes out.

 

Absolute BS. No way a stock port will make power to 11k RPMs. I don't care what throttle body mods you've done.

 

yea how did you make 11k ???

 

Bridge port

 

I call BS on that, a full bridge will reach 11k but not no stock 6port. A stock s4 stops making power at 7k anyway.

 

you can probably rev it that high and make a mess (especially with an 86 ECU... no rev limit) but it won't do you any good.
