Hmmmm...that sounds very stable. Looks like Ill have to wait for the forge Evo IX WGA as I dont know a decent welder/machinist to modify the Evo VIII forge WGA.

 

Hmmm? I don't understand this modified thing with the Forge WGA. I installed the Forge WGA at the same time as the 20G-9-6 and I had no fitment problems. It might look a little tight, but the WGA does not touch any other part of the car. The thing definitely helps spool up.

 

I don't have a way of posting the graph yet. Peak torque(boost) from 16g came in at 4k 3rd gear pull. Peak torque(boost) on 20g came in at 4750 same 3rd gear pull. I did tighten the wastegate that came with it. The first pull without touching the wastegate only boosted 19 psi. Tighten the wastegate and it boosted to 21 but dropped off to 17-18.

 

Got my reading done from a searching. Should've stayed with the stock turbo for my driving style. Race gas would've gotten me into 11's. This is 20g??? suppose to be is not what I was looking for.

 

You did not need a 20G to run 11's. It could have been done on the stock '03 or '04 turbo. It's all about combination of parts that compliment eachother.

And quite conclusively at that. Just the fact that originator of this thread bought a 'slightly used' unit should raise at least one question. After all, it isn't often that someone removes a practially new turbo because he/she is thrilled with it.


I 'upgraded' to a 6-blade 20G from a TME, and it was clearly a step in the wrong direction.

I invite anyone who reads this to furnish dyno charts that show us something a 6-blade 20G accomplished that a 16G cannot do. We've seen Buschur's 20G-9-5 do what would be impossible for a 16G, but not the cheaper 6-blade 20G. All I've personally seen from the 6-blade 20G is 16G-level performance but with less torque and slower spool at the same settings.

It's been several months since I first presented this invitation to furnish proof and we're still waiting . . .

 

Wow. My dyno sheets show just what you said. Less torque, later spool, not enough top end to even compare. I bought this turbo hoping for a step up performance but instead lost my awesome low end torque.

 

I know I didn't need it to run 11's. That wasn't my goal for the 20g turbo.

 

Can you post up the sheet? Sounds like you've got something else going on...

The spool should be pretty much identical but with slightly better tq. Power was about the same on my 6blade. I have an appt on the 14th to dyno my 5 blade so we'll see how it compares

 

Sorry to hear about your problems. What were your before and after numbers?

 

good to know My buddy has a 20g sitting in his garage I should have him read this post before he puts it in

 

In my case, the peak power of the turbo was adequate, but still only ~10whp greater than the TME it replaced. The problem I experienced was below 5000rpm, where the 20G felt like a slug as compared to the TME, same fuel, no other changes, same boost pressure, tuned to the limit.

The more data we have available, the more accurate of a picture we can paint for the benefit of forum members who contemplate this route.

 

who cares what the turbo makes an race gas. So you are saying inorder to make the most out of this turbo you need Race gas and Alky kit?? WTF ?? all of us are not richie rich to run race gas all the time. What people really want is good numbers on pump. The last time i check stock turbo with race gas and alky kit make pretty damn good number too. So what's our point ?? Either way, until somebody do a real comparison between the stock turbo vs evo 9 vs 20g 9 blade vs 20g 9 6 blade. All of this over hype on this turbo tell me it's a junk.

 

Huh, vboy? My point was that this turbo sucks. Read what I wrote again and let it sink in. why are you jumping on me about race gas and alky when I'm saying that's exactly why it's not very good, especially if the guy is just running pump gas daily. Btw, no one needs to be richie rich to run alky. It costs me an extra $4 per week to have another 20-30whp and 40-50wtq.

 

no harsh feeling. just speaking my mind. It makes nosense to buy a turbo to have more power and find out you will need race gas and alkykit. When you can do the same with stock turbo and make good power with it. but i do agreed with you about just getting evo 9 turbo, i'm thinking of it for myself

Better yet just get one of this and call it a day.
