juxsa · **good turbo combo**

I was reading a thread on **************** where the guy was using a T04E 50trim wheel in the stock housing with a stage3 wheel in a .48 housing. He says he is building boost crazy fast on his 2.2... (its an enforcer3 turbo)

What I am wondering is how that combo would work but with a true T04E housing on a 2.5... not sure if I would use the 50trim or if I would use 46trim. Would I build boost as fast if not faster since its in a 2.5 or would the bigger compressor housing cause more delay. The head is stock and I may or may not have a ported exhaust mani...depends if I can sell my ICs.
I am building street warrior, not a dragstrip destroyer so having quick boost response is priority.

Let me know,

Thanks

who needs boost below 3k? if your racing, theres no reason for your tac to be down there.

Street use. If its a drag car a .48 would kill you but for a car that is a street warrior boost response would be crucial

Beside, what would you rather have, a car that makes power for 4k rpms or a car that makes power for 2.5k rpms? I would rather have the car with the wider powerband

eh, i dont know what im talkin about. when i need boost, i just downshift and let the turd scream to 6500. =)

On a similar note-

I need serious feedback from those who have had sucess with the 46 trim
stage 1 and/ or 2 ex wheel. I have assumed that for a 2.2 stick w race head,
the 46 trim w/ .63 hot housing, lag should not be too bad. Everyone goes 50 trim, but I don't think that's realistic w stage 2 wheel- for my car that is.
Any usefull feedback/ experience welcome.

put a two-step on it and it will make boost in neutral.

If you seriously believe a turbo Dodge that makes full boost at 2000 RPM will still be pulling hard at 6000 RPM, you're newer to the hobby than your post count indicates. Our engines just don't work like that. Look at the Mitsu turbo on a 2.5L, for example. Oh, sure, you'll get some good boost at 2000 RPM... but the power will begin to nosedive around 4000 RPM. Setting up your engine this way won't be doing any favors to your street warrior car (unless your idea of a "street war" is a race from 0-30 MPH).

To answer your question, I'd rather have a turbo Dodge that has a 2500 RPM power band--from 3500-6000 RPM, please. Using a powerband which is only 2000 RPM wide (from 3k to 5k) my 2.5L minivan manages to run 13.5 ETs. Back when I had it set up for lower RPM boost, I went slower. I decided faster was more fun.

I am not talking full boost.... thats crazy. I am taking about making 1-2 psi at 2k rpms... instead of 3k rpms..... powerband starts out a little lower.

the true t4 housing will allow the turbo to spool quicker, same with the fact it's a 2.5

**Shadow** · 03-27-2006, 07:02 PM

We trapped 125mph with a 46 trim T04e in it's original housing with a .63 A/R turbine with stock wheel. It spooled like mad, almost too fast! I would never mate a T04e to a .48 no matter what stage it was, just a waste of time and money.

juxsa · 03-27-2006, 07:49 PM

yeah... i figured out that I am going to go with a TO4E with a super50 trim and a .63 not sure if I am going to use stage 1 or stage 2 yet.... I am interested in hearing about 46 trim wheels though

89daytonaTII · 03-27-2006, 07:57 PM

what's there to hear about? It's a little smaller so it'll support a little less hp but spool a little quicker. And is still efficient in 300+hp and high boost applications.

juxsa · 03-28-2006, 05:19 AM

im interested in how much quicker they spool, what kinda spool times are people getting listing their setup. I know its a little smaller but I want to know what kind of success people are having. Do they wish they went with a 50 trim wheel?

**Shadow** · 03-28-2006, 08:37 AM

Knowing the map of a 50 trim and that it's bigger than a 57 trim (due to the taller comp wheel design) I would use a stage 3 .63 A/R turbine housing to get the full potential of that wheel. If your going to be happy with 350whp stay with the 46 trim and stock turbine .63 A/R. If your going to want 400-450whp go with the 50 trim stage 3.
