e316g vs tdo5 20g on e85

[byebyev8]

I already have a e316g on my car at 28psi it pulls real hard to redline. But I found a good deal on a 20g and I'm woundering if it would be worth it to upgrade. I know the evo3 performs just as good as a 18g but what about a 20g at high boost levels.

The problem is the td05H wheel can't flow enough to make adding the 20g compressor wheel worth while (in my eye's). Now if you where looking at a td06H 20g then yes, go for it. Right now, you might as well just buy a 20g compressor wheel and have it put onto your 16g if your thinking of swapping to a td05H 20g setup.

hmmm.... a local guy here made 511hp on my dyno a year ago on a stock block 1gb..........it was a
td05 20g.

Clipped? Which compressor housing?
Pretty impressive though for any 20g turbine option they come in

You mean turbine housing. Compressor housings make minimal difference. Yea I'd like to know if this turbine wheel is clipped or not. It will make a significant difference on whether or not the turbine can reach the flow most need to see 500 whp. . . Yes CB has made 499whp with the td05h turbine and the 7cm^2 turbine housing. . .

No, i meant compressor housing, I'm curious if it was using the tdo5h cover, but i'm doubting it. I would also like to hear the turbine housing mentioned too, obviously.
How much difference do you think the 8cm housing would make?
I'm also curious how much compression the engine has, cams, etc?
Curt was using 10:1 right? Was he using a clipped turbine?
I would almost think it would be necessary to reach those numbers on a sane motor

It was 10+ to 1 compression. I think more like 11:1 and Nathan said it was not clipped. Mike Huml came on and said that it appeared normal.

Unless you have 11:1, fp4r cams, FP race exhaust manifold, JMF race intake manifold, and the tricks CB knows; don't expect 500whp out of your td05h turbine wheel and 7cm^2 turbine housing.

 

[bastard dsm]

it was stock wheels and 7cm housing, and yes tdo5h cover.....stock 6bolt block.

 

[e85_4g63]

Hold on here, I'm getting a little confused and I think I misunderstanding some things. CB didn't make 500whp on a stock EVO III 16g on a stock bottom end. I think I have that correct. Next thing, he (Nate) stated that when CB's car made the 499whp it was on a built motor, and the turbo was ported. I don't recall any mentioning of EXACTLY what all was done to the motor (besides it being higher compression, c16, etc) or what was EXACTLY done to the turbo (besides it being a FP ported EVO III 16g).

I stated that I didn't feel that putting a td06 20g compressor wheel on a 16g (meaning a td05h turbine wheel with a 7cm^2 turbine housing, unported) would be much benefit just because that, without modification, won't push the 20g wheel to it's limits. THAT I AM AWARE OF. If your talking about clipping the wheel, porting the housing (or changing it out all together) then yes, I feel that adding the 20g wheel would be a worth while upgrade. Although the td06H compressor cover would be more efficient at that point. But to each his own, as they say. I just wanna see the dyno sheet! I'm only trying to argue respectfully!

 

[dsm-onster]

You're right it was NOT a stock block at all. I'm not sure but perhaps bastarddsm was referring to his local guy who made 500+ whp with a td05h 20g. . .

Porting yields minimal flow increase and just using the factory seal ring with an evo3 exhaust manifold will be doing the same thing as porting the turbo.

Yes, Why would you try to get 20g power out of a 16g hotside? It's just so much easier with a bigger wheel and spool isn't very bad. The price may be. The td06 20g does it a whole lot easier, it's a shame it costs so much more than other options that are just as capable and spool the same or faster.
