I want to make my own 20g, how much for just the compressor? =p

 

Why so? Does the Evo IX comes with a 20G compressor wheel? IIRC, the compressor wheel is of the same size as the other TD05 fitted on previous generations but made of magnesium alloy.

Taken off the factory manual :

A magnesium compressor turbocharger has been introduced - a ‘world first’ for a mass production car. (GSR : option GT/RS : standard) The result is even better throttle response. Furthermore, the shape of the compressor housing has been changed, making intake smoother, and improved mid and low speed torque.

I'm thinking that the bigger 20G compressor wheel might benefit from the new shape of the Evo IX compressor housing. From the description above, the magnesium alloy compressor wheel seems to give better throttle response but its the reshaped compressor housing that gives improved mid and low speed torque.

Thoughts?

 

well... mainly because the 20g wheel is not gonna fit into the 9 housing... because the mag wheel is not the same size or shape as the previous wheels. at least not from what i saw in best motoring and the release threads that i've seen on this board. the new comp wheel is "longer" as in snout wise for one at least. and i believe the diameter of the wheel is changed as the housing inlet is also larger.

that clippet you ahve from the manual says nothing about it being the same as other wheels before.

my thots... the evo 9 turbo's wheels are fine the way they are, i thinks this time they've outdone themselves. and evo400 went and outdid themselves.

 

Well, I wouldn't assume too much if I were you. I have a Evo9 for 6mths now and from the info. being released on the 20G, I will be glad to swap out the Evo9 turbo for one. Is the Evo9 turbo better than the MR turbo? IMO, yes. Is it better than the 20G? IMHO, no. Bear in mind that what we get here is a turbo with the TiAL internals as standard. Sure it spools super fast and generates more power than the MR turbo. If that's all you want, go for it. It just ain't the magic turbo that you think it is and Mitsu sure outdone themselves with the warranty claims on this one

Have no experience with the Evo400 version so no comments but I would like to hear from them on how much boost their turbo can hold and if they are still using the magnesium compressor wheel.

 

what more magic is there than that?

 

Is there a way to port a 10.5 housing to get more topend outa this thing? Can that be an option?

 

totally... the hot side you can mix and match however you like with the tme internals and port and polish job etc etc.

 

From what I can gather based on what I've read through out these forums is that; since the 20g turbo at 20psi can do an estimated 360-380whp on a dyno (mustang dyno or dynojet?), from what I'm seeing, the psi produced from the 20g can add more hp opposed to the stock turbo 20psi to 20psi (I'm currently dyno'd at 341awhp@20psi (aemems) on a mustang dyno stock turbo)

What I want to know is when running the 20g TME/10.5 at a higher boost level like 26psi opposed to the stock turbo at 26psi which, I'm sure running the stock turbo at 26psi would require upgraded inernals (headstuds, pistons, etc); would running the 20g TME/10.5 at 26psi require these type of internal upgrades since what I'm guessing is the 20g can handle the psi 'better' than the 16g causing less stress on the engine.

In other words If I did add the 20g TME upgrade with the 10.5 hotside to my car could I hope to see 400+whp (mustang dyno) running safely on my car without upgrading internals.

*Please correct me if I'm making false assumptions my knowledge is so limited here*

 

Where are you getting your dyno numbers? From what I've read on the forums the 20G has yet to show a peak gain in WHP over the stock turbo. Take the Buschur RS. It dynoed 393 whp on the stock turbo and 94 octane on the Buschur dynojet. The car now dynoes 361 on the new Mustang Dyno and David Buschur just posted that this is equivalent to 425 dynojet -- so the car has picked up about 32 whp with the addition of a ported head, 20G, 4-5 psi and 118 leaded race gas. The head is worth an easy 20 whp at this power level. David has posted that in connection with the BR440 buildup. That leaves 12 whp of gain for the race gas and 20G. Even if the stock turbo was maxed out and couldn't make more boost, the race gas would allow a lot more timing. That would more than explain the 12 whp. What does that leave for the 20G? More power from peak to redline is the answer I think -- just like the WR turbo. From what's been posted so far, I think anyone buying a 20G with a less than maxed out stock turbo is going to be disappointed if they are looking for a significant PEAK gain.

 

i htink 400 hp on mustang dyno is quite a bit... dont think you'd even hit that with a 3071

 

My turbo does my laundry.

 

This is what the first post of the thread says this is only his guestimate though not a real dyno number that the 20g at 20psi was producing possibly 360-380 whp. So thats why I'm assuming that based on that assumption that at 26psi it would be 400+whp

 

I just ordered the TME 20G from Buschur Racing, I will have dyno results somewhere around the 15th of October when I get back from HIN Phx!!!

 

I ordered the TME 20G, ported exhaust mani and 02 housing from BR. Turbotrix is doing the install on Oct 10th so hopefully with a good tune I should see some decent gains along with the Buschur stage 2 getting installed at the same time. I hope for around 330whp @ 21psi...is that too optimistic.

Just for comparisions sake, what does stock evo8 put down on your dd?
