Had a look at the new WR Rev2 production manifold today. I approve!

Some slight changes I noticed; the stiff pl's coming off the top runners have been changed a bit, welds are also cleaned up a bit more and overall product seems much more refined. I like the new emboss logo on the manifold, is a nice touch. I spotted the new nipple between the bottom two runners, I think it might be a touch larger for overall volume as well.

I didn't think this product could get any better, but I have to hand it to the guys at WR, very nice job bringing this manifold to full production with this kind of quality. It looks outstanding!

Looking forward to installing it, will be doing a full long term review w/ some dyno results in about a week.

 

Heat soak problems?

 

^^^No major issues, was able to run a full day event on a hot tarmac in scorching heat with no overheating problems. The engine did not suffer any power loss as a result.

I will say the engine bay is hotter without the heat shield on the header at the back; which means the manifold will get hot to the touch after running for a while. Might be a worthwhile investment in getting a vented hood, however is not by any means a requirement.

I have been looking into ways to get more airflow under the hood, lots of ideas on the thread I started about it. If somebody was really anal they could insulate the entire manifold, it opens up a lot of extra room and would be pretty easy to do. Here is a link to the thread, have a read through if you have time;

Just Mocking up the Thermal Guard Gasket for in-between the Manifold and Cylinder head.. Should be released very soon.. This will be a very good add on for guys who use our intake manifolds..

 

Interested!!

I installed the new Manifold today, really great work on the attention to detail. The edges have been beveled all around, emboss logo and serial have been added and fitment is great! It went on in about 15 minutes.

I noticed the velocity stacks inside the housing have been extended out about an inch as well. I think I have gained power throughout the power bandwidth, I pushed the gas down as I was merging onto the highway today and I could really feel the difference.

Dyno on the 6th Stay tuned!

 

This is mostly pointed at WRLEO but I got in on the first go around for the intake manifolds and I still DO have the CEL light is there a way to fix mine or am I expected to buy another manifold????

If you send it back in we will modify it for you.. Im sorry about the problems you have faced with our product but we will stand behind it 100% and assist you to fix the problems.. Please email chris.agloro@weapon-r.com and he will assist you in sending the manifold in and modifying it also..

 

Tagged for interest. Keep up the good work WR!!

 

IT'S DYNO DAY!

T-2.5 HOURS

 

HURRY UP ALREADY YOU ARE SELLING ME THIS PART.

 

very interested to see the results!!

 

Any results for Dyno??

 

Results thread in progress; be up in about 10 mins or so

 

Stumbled onto this old @ss thread via google....no dyno results?

 

i had dyno results but it was when i was boosted and i had upped the boost 3 psi so the IM gains were skewed. i can say, it adds good throttle response and makes the car breathe better.

 

Thanks for the reply...

I don't see a dedicated GE8 IM...but it appears that the L15A is largely unchanged between the GD and GE models. Can anyone confirm if the GD IM will fit the GE?

 

lol, this is an old thread man! I am still active on here though.

Basically I took it in for a Dyno... which didn't go well, there was something off. We found out there was still some issues with the EGR on the Rev2 version. The results were basically a throw away.

WR had another close look at the manifold, they added some channeling into the face of it which re-routed the EGR correctly and I tested out the Rev3 version on my car shortly after.

Basically the Rev3 version has been on my car now for close to a year and a half... no problems at all and there was a substantial increase in power. The Rev3 is the version that WR went into full production with, it works flawless on my car.

I tried to line up a Dyno for last spring, after scheduling the appointment 3 times, I was brushed off at the last minute by the operator. So I ended up giving up.

Hope that answers some of your questions.

The changes between the GD3 and GE8 are sweeping, everything from operation of valve timing to the new integrated exhuast manifold has been added. You need a GE8 manifold, GD3 will not fit.

 

What were your gains?
