[bmw335ikt]

I'm about to pull the trigger just want to see what's the better option
Brand new fp 68hta
Or
Mhi evo 3 16g rebuilt

Thanks

If you're going to "Google It For Me" then at least search the right thing, I don't care about quarter-mile times. I said show me these countless builds making 400WHP on a 16g running E85 over on EvoM, does a DSM running a 10 second 1/4 mile with a 14b make 400whp or does it weigh 2,000lbs?

Thanks for playing, now LMGTFY.

EvoM DSM 16g E85 400hp​

You'll find that there aren't countless threads that appear, there are two threads with actual DSM's in them. One is a auto 1g running E85/meth on a Evo III 16g with a charge pipe going straight to the IM (no intercooler) and the other is actually my own build thread that I posted on EvoM years back.

The point is, there aren't countless build threads on EvoM showing DSM's comparing these two turbos let alone making over the 400whp mark on the Evo III 16g. Of the thousands of DSMer's running a Evo III 16g you'd be hard pressed to find more than a few dozen making 400whp.

I see countless threads.

Guess learning how to and having done for you, are two different worlds.

OP keep reading other various threads, you will find the 16g will best fit your wants if you daily your car.

ECu flash and tuning is so hard to learn!

Nice. Lucas English can do it so can everyone else, I guess we should all expect to run 9's with these HTA68's then? You still don't get it bud, the point is there aren't countless threads on EvolutionM (a specific website) nor are there countless threads of DSMer's running 400whp+ using a 16g and E85. There aren't even more than a few threads of DSM's running north of 400whp using the HTA68...

Even the thread you linked to the car was tuned on E98, even though you Google searched E85.

There are actually quite a few Evo 9s making over 400 WHP on the stock turbo....That is actually true. I made 400 WHP on pump gas on my evo 7 w/10.5 housing @ 30 pounds of boost in Japan. However just because a twinscroll Evo can do it does not mean its apples to apples comparisons when talking about DSMs. Not only are they different platforms but also twin-scroll tech which I think is the majority of the difference. Full Race are some of the firm believers in twin-scroll technology for spool and for power. I could elaborate however I am sure others can give a better physics explanation.

I have also run the (single volute...Evo 3) 16g in my JDM Evo 3, as well as the DSM 68 HTA. What I can tell you is there is a significant difference between the two turbos. It's really not even close. Regardless of what people think, Gofer's 440WHP build is impressive in his variant of 68 HTA.

So for those internet warriors who think making 400 WHP on a DSM 16g is easy, then I suggest you go out and do it rather than talking sh*t.

Don't hold you breath. I see this BS all the time. People saying I did this or that, or my dad's grandpa's cousin made blah blah blah on a T25 @ 60,905,049 psi. Accomplished results of the few made readily available by the internet create this stigma that 400hp 16g powered cars are just commonplace.

Seldom do I ever see logs, slips, or hard evidence to back up all the lip service. I'd like to see countless logs that show airflow numbers on a 16g to support 400hp.

I am by no means a turbo expert... but why not look at compressor maps as well as compressor flow... seems to me to be the more scientific way of settling the debate... With every car being a bit different, even on "identical" setups it would be safe to assume that results can, and will vary.

It doesn't get much more scientific than a data log.

Logs are ground truth, IMO. There's no snake oil, BS, or lip service in a log...Just hard data.

Grab the fp turbo and have something to grow with is it still on sale.

 

[Liquiddetail]

Eh a log on a car is still subjective to the setup. A controlled environment where flow at a given RPM is not subjective.

 

[GST with PSI]

Why would you care about flow at a given RPM in a controlled environment when those conditions would never exist in the real world on a real car? You should be using a compressor map to select the proper turbo for your setup, and a data log to confirm that turbo is performing optimally in that setup. Most will find what a turbo is capable of on paper, and what a turbo is capable of on a real car in a given configuration will differ greatly. Data logs provide information to support the latter.

Yes I do, unfortunately. I had every bolt-on/supporting mod running my 16g on 91oct (not everyone has access to 93oct) and this is the best I could do. Stock 7-bolt s16g Dyno

It was on a s16g but as I mentioned, I ran every variant (big and Evo III) on the same setup and didn't see a change in airflow numbers or trap speeds at the track. I literally popped and swapped the CHRA's/compressor housings from each 16g into the 7cm turbine housing I left bolted up making no other changes and saw no gains. I was limited to ~21psi and very little (8* peak) timing advance because of 91 but I would expect similar results for most 16g setups running the same fuel.



Here's a my dyno printout after the HTA68 swap.

The RED line is 91oct and 21psi (peak timing was 8*)...
The BLUE line is E85 and 28psi (peak timing was 17*)...

You must be logged in to view this image or video.

Just swapping to the HTA68 and retuning the car on 91oct the car went from 260awhp to 350awhp, keeping AFR's/timing/boost the same. You can see what a increase in boost/timing advance does running E85 with at HTA68 setup and this is on the 7cm housing. Currently I'm on a 8cm BEP hotside and accurately logging over 52lbs/m on the same turbo so my butt dyno's telling me I'm ~450awhp now.


HTA68 all day for that price FP's selling them for. I wasn't aware that FP was selling these with their 18psi actuator but, if this is the case, you can pickup a used td05 12psi wga (stock on 14b/16g) for <$30 and it will bolt right on until you can get the proper supporting fuel/tuning modifications to run more boost.

Another thing to consider, if you've got $600 burning a hole in your pocket you can spend your money better elsewhere and pickup ECMLink. Which is actually the best option from the two choices you posted, you won't be able to really benefit from either turbo install at the point I'm guessing you're at in your build @bmw335ikt. Maybe look at getting ECMLink first?

Do you still have the car, was it mostly race? did the turbo setup you had cause any mechanical breakage? I was looking to upgrade turbo, I just want my 90 gsx faster but I want it to last a long time. Thanks in advance!
