Power Wedge Upgrade!!

So I went ahead and ordered one. I figured $99 shipped, what they heck...might as well. Especially since I spend that on beer every so often lol!! So anyway, the wedge looks ok. It's a nice clean easy install. It's inconspicuous. The only hiccup is that the fitting was a bit weird with the Vararam CAI. The TB pushed forward puts the rubber sleeve of the CAI right onto the engine most part of the MAF housing. So the clamp looks a bit crazy. But everything fit snug and there are no leaks so I'm ok with it. Otherwise the install went smooth.

The engine started right up and the idle is fine. I did not get to drive it yet. I have all the mods in my sig and I'm in the process of getting my custom tune updated...since it hasn't been updated since I got the cat-back and the CAI. I datalogged and had the tune re-written last week. Since then I put about 120 miles on it. So I figured I'd put the wedge on now and then drive it for about 100 or so miles and then datalog again. I don't know if I will notice anything with all the other mods and the custom tune, but I'm hoping I do...even if it's just throttle response. I will drive it in a bit and update you guys.

Any recommendations or suggestions will be considered. I know the whole back and forth debate about whether or not the wedge possibly works. Which is why I need to know for myself first hand experience. I will post again after I do a test run.

It's supposed to straighten out the throttle body since its at a slight angle. It makes for better airflow according to the manufacturer. Vararam and a few of their sellers have claimed HP increases. It can't hurt... it really hasn't been proven either.

It is basically a throttle body spacer that goes between the throttle body and the intake manifold. There has been some debate over whether or not it works. I haven't seen any evidence on either side to sway my opinion. So curiosity got the better of me and I bought one. If it works, great. If not, then at the very worst it won't harm my engine. So I can live with that. I will post some pics up after my test run.

I know some people says it helps and some say it did nothing. Hopefully it helps some. Like you said tho, $99 bucks, it's worth a shot!

I took the time to benchmark it for the community doing three pre and post dyno pulls. Average 8rwhp/rwtq gain at peak. People decided to ignore the results however

Post a link please Falundir? I must have missed that thread somehow.

Well guys, I really don't want this to turn into another debate thread. Like I said before, I bought it out of curiosity. $99 shipped is worth a shot to me. And again, there wasn't enough evidence on either side to convince me one way or another. And all the debating in the world won't convince anyone except for those like me who have the tendency to try things out. So take my words either way. But this is how I felt about the upgrade.

I drove the car and I personally think the results are positive. The car feels like it pulls harder and faster. And the throttle response is better. Would I buy it again? Absolutely! Am I happy with the results? Definitely! Would I recommend for others to try it? Yea I would! I don't know if others will feel the same way or if they will notice the differences. But I did. And no, I do not have any before/after dynos to show. I used my butt-o-meter. It was a worthwhile purchase as far as I'm concerned.

We did testing on my personal car months ago, if you do a search you will find it. MY CAR showed about 8whp 6tq if I remember correctly.
I did not touch the tune, and was Cammed/Headers/CAI at the time (Pre-SC for me)...

Not what the claim was but for 100$ not a bad $ to hp rating...

Is it a must have? no. Is it an ok addition to someone trying to maximize NA? sure. If you dont feel like searching or anyone else cannot find it I will search threw my post history for you, just let me know.

Good that you're happy with it. Do you have any means of datalogging your car? I would think the change would show up in your fuel trims.

"It's not a spacer, it's a power wedge!"

There have been several "independent" tests done... I, myself tried it out on the dyno, it's floating around some where if you do a search... IIRC is did show a gain, but I kept having problems "keeping it sealed"... It seems like every week I was trying to tighten it down because it was whistling and my fuel trims were out of wack (vacuum leak).

Yea I will datalog tomorrow night. I have the last file I datalogged with on my computer. And I have a file from a few days ago when I was monitoring my IATs. That file is still on my Predator. I will try to compare the them and see what I get.

Nice. I would expect to see your LTFTs increase if it were indeed feeding the engine more air. This really shouldn't be that hard to prove/disprove.

This could also be seen from a vacuum leak... Pay attention to this, whether it's caused from "natural causes" from the design of the power wedge, or if it's a vacuum leak. Several people have reported them.

I can see how the gasket can potentially cause an issue. It isn't a "perfect" fit and I can see how it may leak. However I feel pretty confident in using it. I will keep an eye on it. Maybe sometime next week I will go back and check the bolts and see how the gasket is holding up.

$99 for 8hp if that is even the case i'd be interested if the results were really there and could be proven! Interesting. Keep us updated on this.

still no one has posted a thread with dyno numbers. im sure the thing has some positive value and im almost positive it will improve throttle response even if there is no horsepower gains

No issues at all with mine after 4k hard miles.

No leaks no whistling.

Mine showed a 10hP gain at lethal.
From the stock ported to the ported with wedge.
