FP/Buschur's new HTA GT35R turbo (HTA82)
This has been a long time in testing, but Robert@ Forced Performance and David Buschur have finally brought their HTA GT35R turbo to market. *all* this is is a standard GT35R with a custom designed compressor wheel. The wheel itself is actually *smaller* than a standard 35r, and thus it spools sooner--almost 400rpms sooner on a 2.0, and power ends up hitting the same level On a 2.3 or 2.4, this sucker would make a great street setup.

Re: FP/Buschur's new HTA GT35R turbo
finally! I know alot of people on the evo forums were waiting forever and bitching . So for the record it's a 35R with a custom compressor and a mitsu style turbine housing?

Re: FP/Buschur's new HTA GT35R turbo
Here is a very nice review by Mellon Tuning about his experience with this turbo.
http://forums.evolutionm.net/showthread.php?p=5064686
This thing makes me want to forgo my plans for OEM turbo power and go big....it makes me crazy!
Look at the torque curve some of these guys are seeing, leveling off at ~4300rpms, that is just insane! People are actually swapping out BB T67's and seeing modest power and insane torque gains!

I think Scheides loves this turbo more than Apple.

Re: FP/Buschur's new HTA GT35R turbo
First of all, I agree, stop stroking this thing and buy one already.
Second, to be honest, that HP curve is kinda ugly. Looks like a Honda VTEC curve, or a supercharger curve.

Re: FP/Buschur's new HTA GT35R turbo
I would really be surprised to see power gains over a dbb t67. maybe at a lower rpm range, but overall the t67 should make more power.

Re: FP/Buschur's new HTA GT35R turbo
The first example is right here, I expect more to follow. Please note, not insane gains OVER a 37R, but power is SIMILAR to a 37R (37R = bb T67 slizang), and torque is much higher, which is what makes this thing amazing IMHO:
http://forums.evolutionm.net/showpos...6&postcount=18
"Compared to the "37R" kit that just came off the car it's up 13 whp and 80 ft lbs of torque."
Also of note, this car had the .86 turbine housing on it, and saw no power advantage over other cars with a .68 turbine housing, but spool is ~500rpms later (torque curve levels off later).
...Sorry for saying people were seeing 'modest gains' over a T67, I meant to say modest gains over a standard 35R on par with power levels of a bbT67...

Re: FP/Buschur's new HTA GT35R turbo
Now thats a better curve. But I'd like to see a 35R and a 37R sheet overlaid on top of this sheet. We then could see the difference in spool up and hp/tq curves. Seems a bit on the laggy side, I guess that is the .86 housing.

Re: FP/Buschur's new HTA GT35R turbo
Here is a graph from 9sec9's 37R'd evo(similar mods). If you compare it to the graph above, you will notice a few points
455wtq: 37R@6150rpm HTA35R@5100rpm (1000rpms earler!)
@7000rpms: 37R has 455wtq HTA35R has 470wtq (about the same)
@7500rpms: both at ~440wtq and ~640whp
37R:
HTA35R:
edited to add in the other turbo we're comparing here...

Re: FP/Buschur's new HTA GT35R turbo
.86 and .68 A/R turbine housings on which turbo? .86 is a weird size.
The 37R that AMS sells is a little smaller than what we would normally run for a 67mm turbo, because it normally uses a little T3 .63 5-bolt exhaust housing for quicker spool.

These are buschur turbo kits, and all on the 35R, except for the one bbT67 I posted, all T3 turbine housings. I don't know specifically if they are the ford style, or what, just commenting on the dyno graphs really.
