I consider Aby to be a friend of mine, and I am by no means trying to start a war here. Aby does GREAT work, but to say you could gain 25hp from a 65mm TB is insane. Aby personally told me that his 65mm TB is good for about 5hp and that is about it. He did say the real benefit is increased throttle response.

It is my personal belief that the fairly significant gains shown on the dyno graph above are a result of tuning and not the 65mm TB. I believe the car was not optimally tuned, and James Reese did a GREAT job tuning the car and making it achieve its full potential.

Please note that I am not hating here. I am simply stating what Aby himself told me, and I don't want people running around thinking they can bolt-on a 65mm TB and gain significant power. It simply won't happen.

 

Charlie, I think Alain has that info on SoCal. He should be posting it up there, but maybe we can get it for here too

 

thanks Erik.


about the gain, to be honest, we tested on our dyno we have seen anywhere from 4-8whp on our Dyno Dynamic. But what really impress me is the throttle response. We have been selling Milspec TB since 2005.

 

On my personal dyno test in front of ~20 socalevo members a while back, charlie was one of them, i only saw an average of 5.5 whp with a 8.x max gain.

The gains experienced on the above referenced dyno chart does point out, that some engines can respond better / have the ability to take more timing then others when a tune is optimized for it's components.

Should everyone expect to receive such massive gains.... Not at all.

They will experience tremendous response gains, great for people who daily drive big turbo'd car's who hate that mushy feeling when stepping on the throttle around town or on the freeway or for all auto crossers, as the response will allow you to rotate the car through a turn; mid-corner - out, in a more predictable manner due to the increased throttle response. The engine becomes connected to your foot & any throttle input.

For any of you auto x's that want oem screws to be applied, let us know, this tb will go un-noticed externally & will slip by most tech's if they pull your uicp to inspect

I would figure ~6-10 whp throughout the rev band to be the norm...

As a lot of people see on these boards, there are some fortunate evo owners who posses a car/engine that responds well to mods...Lucky @#$%

 

this is some good info. i have not considered buying a larger TB or have the Imani ported, but i just might have to do this in the near near future.

 

PMed about a custom cat...

 

PM will be returned shortly

 

Aby, I just sent you a PM. I want this TB and I'll send you out the intake mani for porting as well. Hit me up.

 

I'm glad that we all agree that modifying the shaft for improved flow is a good thing

 

Bump for properly machined, Works-seals rebuilt, fully 65mm ported, TPS spec'd MIL.SPEC throttle body hotness

 

im almsot ready for it... when Mikey comes back from BW TA were rebuilding the car... first track test Apr. 19th, so maybe before the track test date.

Thanks Aby. I got my TB today & it looks great. Can't wait to get this thing installed.

 

Aby - I just realized I left my IACV on the TB when I sent it to you. Hope thats OK....

 

I'm sure it will be fine. Aby's like wicked smaat.

 

I sent mine with everything on it & got it back the same way.
