No power gain from Underdrive Pulley?...

And dyno charts with compensation numbers "built in" for gearbox / transmission losses are pure nonsensical - who wants to prove that a gearbox soaks up 12% or 15% or 20% of the rated engine power output, let alone adding in different daytime barometric pressure, temperature and rolling road calibration changes.

Makes perfect sense.

I wish Jake Raby was still allowed to comment on here. I'm sure he has a lot to say about this

Bummer... Jake has helped me 3-4 times both on and off this forum.

Hopefully someone will realize the value that Jake has added to all of our forum members and does the right thing.

It may not be easy, but sometimes we must think above ourselves for everyone's benefit and the continuous growth of this awesome community.

To be clear:

I was the one that made the decision to no longer post here. This was done after I helped to create a company that can be considered a rival of Pelican Parts, who of course does own this forum. I decided not to come back this this forum after that exchange, as it was the most courteous way to move forward.

The word "ban" was never stated by anyone, and it was a peaceful exchange between all parties involved.

This is the first post that I have made here since that exchange, and I felt that the air needed to be cleared before things went downhill.

"Wacko- out!"

I have a few comments to ad , I will preface that I am a Jake raby fan for many reasons . Jake does not do well with idiots and because of that comes across as brash and arrogant . To talk to him in person and to deal with him on a daily basis is quite different .
I have told Jake many times he is a nut , but I mean that as a compliment . He is 150 percent driven on taking something that is weak , abuse the heck out of it to break it and then come up with a solution. In many cases we can repair our cars because of him. No I am not a paid spokesman just a very happy customer .
I actually talked to Jake after " the ban " and I was quite surprised . I have been a long time customer and fan of pelican parts . Great forums , completive pricing it is a great combo . But by banning competition seems petty to me but it is not my forum . I can contact Jake any time and get a reply generally within hours.
There are exhausts out there that can add HP/torque but most are overated . I base this on real world data on Jake's dyno using OEM , dansk , ghl on my 3.2 and 3.6 beast . I have an under drive pulley on mine also , installed by Jake . I was never promised any HP increase but was told quicker throttle response would be a result and easier on all the ancillary belt driven parts .
Ok end of my speech but I believe this forum is now less useful than it could be because of the ban . Go falcons !!!
