I installed the TB and did not get it retuned for a few weeks and it felt awesome. After getting the ECU reflashed for it and some other mods, it was even better.

 

Maybe someone should ask Dynoflash if adding the throttle body is cause for a retune. I know Al has been using the WORKS Aperture throttle body for quite some time now with race proven results.

 

Just wonder if it would make things dangerous.

 

I know WORKS has a different flash for the throttle body upgrade.

 

Maybe Ive never seen AL post about it but he usually if impressed with a product will mention it.

Al has from what I have seen not recommended the throttle body..

I heard from RRE guy had that throttle body and it was causing idle problems..... I was going to buy a used one untill I heard that...

But im sure if tuned right will provide some gains...

 

This is a thread Al started regarding the WORKS throttle body:

"Works throttle body - two thumbs up"

http://www.norcalevo.net/forums/view...=throttle+body

Damn, hearing all the good feedback about the WORKS Aperture makes me want to get one!

 

As I understand it, Al have been using the WORKS TB since pretty much from the beginning. That was what I was told when I first visted WORKS during late 03.

 

Adding an upgraded throttle body does not change the tuning needs of the car. It simply changes the throttle response characteristics. This means that a smaller throttle opening with the a larger throttle body will induce the engine load/boost of a larger throttle opening in with a smaller throttle body. There should be power gains associated as well as it does theoretically reduce pressure loss in the induction system. But its reasonably small since there are other, far more restrictive, components in the induction system (namely, the IC). Upgraded TBs will make a car feel different but that's not always the same thing as making more power at WOT.

I agree.. Its important to address all the restrictions in the induction system if you want to make the most of these sorts of modifications and get the best gains.. Its the net of all these changes that makes the best improvements..

 

Adding an upgraded throttle body does change the tuning needs of the EVO.
There are power gains associated as well as it does reduce the pressure differential from the intercooler plumbing entering the intake plenum.

We offer the original Aperture which is port matched to the stock intake manifold and the Aperture II (in the WRP) for those running larger, aftermarket intake manifolds.

Actually testing on my car back in the day showed a 8 whp at 330 whp levels ( upgraded fmis and pipes)

I am not sure what it would add on a stock car

So far I have squeezed 667 whp thropugh it - so it has plenty of capacity

 

How much power do you believe the Aperture provides in a stock or P2'd EVO?

EDIT: just saw your claim on your website of 10whp. Is that on a stock car?

EM@Works -

If you can show me "before and after" numbers, preferably a dyno chart, you'll certainly sell me an Aperature, and you'll probably sell them to a great number of others here who like tangible, empirical data.

 

Yes, I'd like to see this too.

 

The WORKS Aperture has been around for a while, one of their first offerings to the Evo about 2 years ago. So far everyone I know that has one says it's one of the best mods they've ever done. Props to work on another innovative product.

Hopefully I can get one for myself soon. Was gonna do the accufab with the BJ's manifold, but that's too overkill for me right now since the new turbo isnt going in for about 6 months.
