Anyone get pricing for the 8374 yet? I also have a BNIB Garrett divided T4 1.06 a/r GT3582R fs.

 

does the T3 undivided exhaust housing have that snout at the end?

I'm after something that is a replacement for the HKS 3037 turbo and/or Garretts 3076.
I was looking at the 7670.
T4 is out of the question at the moment, the current turbo is a T3 single scroll.

Will this work?

 

ok here is a very quick and rough outline of these 2 graphs put ontop of each other





does that look about right?

 

As soon as pricing is finalized i will be getting an email and i will post it. Im expecting the 83-74 to be around $2,400 +/- $100.

 

the T3 housing is internally gated so its gonna have a snout.

the only housings that will work in some current kits are the TS T4 externally gated.

 

Hey Geoff,
glad I waited to upgrade my turbo setup.....

I'm interested in the best response on a built 2.0L motor.
What type of difference would I be looking at betwen 7064 with the .92 A/R and the 1.05 A/R in spool and power output? leaning towards the external WG setup due to past issues with internal WG issues I've had.

My focus is repsonse, and most usable power.

 

Divided T4 is worth the trouble. Believe it!

The divided .92 is what you want.

 

I think you'll have to wait awhile for this to happen. BW may eventually offer what you want, but in the meantime I don't know of anybody with plans to do so. I thought CBRD might do something like this, but Chad Block told me:
"Im sorry, we do not do anything with BW turbos.
You may want to check with ATP turbo, they do a lot of their own castings!"

 

Just Called Full-Race.

Pricing should be confirmed in the next couple of weeks.
Turbo's will be available in January for people that pre order and pre pay.

Cheers, Mike

 

not unless you believe the BW flows 65/lb min at .4 bar of boost

 

I'd only use the maps as a rough comparison. It's like trying to compare cars from different dynos. We're not sure how each company measures or defines compressor surge, efficiency, etc. Still interesting to see.

The bottom of his chart is wrong, but show me a 2.0L that would run down there anyway. It is slightly off up top too. The EFR 76mm would likely lay almost right over the top of the GTX76 on the right side of the graph.

Compressor flow wise, the GTX and the EFR turbos look very comparable for a given exducer size. The EFR has the wider map in almost every case. Combined with the lighter turbine and twinscroll, the EFRs might dominate a GTX turbo in powerband. I doubt they will go any faster in a drag race though.

 

Regarding the above few posts, I think that another consideration for at least some of us would be how well does the turbo perform at moderate boost levels (mid to high 20's) on straight pump gas without meth injection and without E85. Yeah some of us still don't have and may never have E85. It's always nice to know your turbo is capable of 600 hp on race gas at 36 psi of boost or whatever, but pump gas performance could be the daily reality for a lot of us.

What reminds me of this is the recent finding by Evolutionized8 that the PTE 5857 can make some good horsepower on kill mode, but it is not that great a pump gas turbo. Same conclusion about that turbo was reached by user A BomB in the SRT4 forum, a few months ago. Same prediction for the 5857 (vs the 6057) was made by Mike@AWD but I don't know that he was ever able to confirm it before the 6057 was cancelled by FP .... I mean AMS .... I mean PTE. Sorry.

 

got pricing on mine! (83-74d 1.05 t4 ts) $2k with shipping!
