Default 2.0l HTA68 Dyno & 1/4 mile "NOt a Bad Lil turbo"

So I have had the hta68 for about two months now and finally got it tuned....


The bottom line was from the vf39 it was pretty much maxed out, and a fun DD.
The top line is from the HTA68 which still has lots of room to go, This turbo was just starting to wake up at 20psi. You could hear it coming alive by 21psi, We stopped the tune at 21.5psi due to the maf sensor(set 4.6v). The car feels great it pulls hard and linear all the way to redline, when the vf39 on the 2.0l died at about 6,000rpm's.

Power mods :
HTA 68
DW 750cc
UEL headers
Invidia uppipe
Turboxs Bellmouth DP
Perrin Dual tube CBE
Perrin Inlet
Perrin SRI
Perrin EBCS
Ported and gasket match CSS tmic
Aps bypass valve
Cobb pulley
Cobb Ap(pro tuned)

So I took the car the track and it was hot and humid. Tha car preformed well for weather conditions.


It def. as 12's in its future

I have a couple more videos just havn't got them off the camera yet!

The spool looks pretty good! Not to be rude, but I would expect that trap speed to be a bit higher. I was trapping 109+ on my EvoIII with very similar mods. But the temp and the heat-soak of the TMIC could have everything to do with it

I do plan on upping the boost, just waiting till I can install exturnal wastegate, and big maf housing, with a retune. Looking for 23psi


Yeah I thought the trap speeds would be more around 107-109mph, but none the less this turbo is def. pulls hard

what the hell is all this nut hugging with this turbo? seriously. just save the cash and get a vf39.

you might be really surprised how little it "wakes up" as you can obviously see that boost is falling at redline

+1. I don't really see much difference b/t this HTA68 and an EVO3 16G. FP is really doing a disservice by not putting this turbine in a TD06 compressor housing w/an 8cm exhaust side. The turbine may have the capability to flow 47lb/min, but in a TD05 compressor housing w/7cm exhaust side it clearly does not. FP should atleast offer an 8cm option.

Will you wake up and read I had a vf39 and wanted a little bit more power. What turbo dosn't loose BOOST at redline on a 2.0l??????

I bought the hta before their were any numbers or dyno charts available. It's no dif. then you buying saab and making it STI. To each his own keep the neg. comments to yourself.

I'm not surprised at the trap speed, it's about right for the numbers. Hot weather sucks... I'm curious to see how it does at 23 pounds, as well.

Or it's tuned to lower boost at higher RPMs because the MAF sensor on his car can't scale high enough...
Since he already had a VF 39 and maxed it out, he's obviously looking for something that gives a little more on top, while still maintaining the lower RPM spooling characteristics of a VF 39, it seems to work out well for him.

Since he's just started, and hasn't even begun taking advantage of whatever top-end it will have with a bit more boost, and it's already achieving what his maxed out VF 39 was doing, so far it's a great match.

NVM the last bit of comments, why feed the fire?

I don't think he was questioning your purchase, just the gushing that some people are doing about this turbo. IMHO it is over hyped.

The graph looks descent, I like that it makes plenty of power after 6k but im not impressed with the timeslip considering a tdo4 can trap that or higher.

I personally think that those numbers are a bit higher than one would see on an Evo 16g.

nice numbers. I have two quick questions:

1. Did that HTA68 have the porting option?
2. How much room was left on the injectors? Do you happen to know IDC?

Really, even though his numbers are on a DynoJet? I am not so sure about that.

1. No, the porting was not an option when I bought the turbo

2. The injectors are at 76%

No excuses but it was over 90 degrees when the car was tuned.

Wait... WHAT??? Let me try to say what I think you're trying to say...

What i'm thinking... FP needs to offer this in yes, a td06 compressor housing, but also with the td06h (or sl2) turbine wheel as an option as well as 8cm2 turbine housing. I mean, for crying out loud, it's standard on the 20g, which flows, technically speaking, 3 lbs/min less on the compressor side. This turbocharger is being handicapped at birth.


And to the OP, nice results on the dyno, but ummm, slip... yeah. Better luck next time???

Well said. Yes, that is exactly what I am trying to say. Thanks for clarifying/correcting.

Judging by the comments on nasioc I'd say it's overhated on more than overhyped

For $900 what has this turbo done everybody wrong??

Have your tuner rescale the MAF out to 5.0v, the 4.6v limit is a factory setting easily changed. There's no need for a BigMAF on a 2.0L unless you are running a 20G or bigger on race gas.

Agreed. Rescale the maf and up the boost prior to buying new parts. You should have no problem hitting your boost target with the maf voltage rescaled.

Not boasting, and just for reference, I went 12.01 on the stock vf turbo (C16). My car makes that power now, everyday, with less boost and less timing, while carrying more power from 6500-7000 (HTA68). Its not the answer to all turbos, but if you want literally no lag (on a 2.5) and a low 12 high 11 second everyday ride, this is the turbo to get.

you need to put a disclaimer

: "low 12 to high 11: with a good driver ONLY"

IMO this turbo is not a good option if you are running a VF39 to the max like myself, the return is not enough to me to justify the price

Juan, are you saying that this turbo on e85 wouldn't make a big enough difference in power over a vf39 to make it worth buying? Maybe if you intended on doing what mikey did and going from a race tune to a pump tune, probably not, but e85 to e85, i think this turbo would walk all over a vf39.

Mikey run 12.1 on 93oct and 12.0 on C16 with the VF39, there is the same posibility that this will happen with this turbo. I live for track numbers not dyno numbers .

Thanks I'll have the maf rescaled to 5.0v, and up the booost!

I still believe that this turbo a an upgrade over the vf39, But only time, more boost, and more seat time will tell the whole story.

I can't wait to get my car back to track for a couple more passes(hopefully in better weather conditions).

But for now its off to Englishtown Road course on Monday July 27 To try and find out how my car and this turbo handle the twists and turns. I'll post pics in a new thread after the event on Monday.

I can see your logic, but this is no where's near the case. That 12.19 on pump was on a rediculous map. This pump map on the HTA is a map anyone would get walking into a dyno shop.

Im leaving a solid 50whp on the table with this turbo for now at LEAST (with good octane of course). On the shops DD dyno with 1.2 correction I dyno'd 350-360 (spot on with area dynojets BTW) For reference, SPEED posted a plot from puerto rico in which a car with the same set-up as myself made 359whp.

What im trying to say is, turned up on a dynojet 390-410 whp is attainable on 25-26 psi and a jackload of timing. I will try this once, post results, go to the track and upgrade to a 30R

OP, just FYI, your 39 setup was no where's near maxed out.

Remember, people are not understanding why there is hype behind this turbo so often. But, who has actually turned this thing up yet?? No one really.
