And that right there is the real problem. If it is on a dyno sheet it must be true. Not having a go at you mate, but this attitude needs to stop. It does wonders to sell products, but it does nothing for the hundreds/thousands of customers who spent their hard earned cash on a turbo expecting it to perform like a turbo making these numbers and it doesn't.

A 411whp full weight 3500lbs WRX/STi should trap at least 120mph - most HTA68 WRX's are lucky to break 105mph, and that right there says <300whp.

Why are you arguing with me?

I can't get my hta68 to respond that well, but I did just post the log 3 posts ago. I have to post in the data log thread for it to be worthwhile? What is wrong with this thread? At any rate, I don't have the specifics on tire size etc... but when I did plot it a few months ago with very conservative numbers for the values I wasn't 100% sure of it was 370+ whp. The guy that tuned it said he got 400 on the airboy. Either way you can tell by the log that decent power is being made. I am sure we can both get a pretty good idea of power when we consider boost, timing, even if the MAF wasn't scaled perfectly you tell from the log that good power is being made.

FWIW I can't seem to get much more then 18 psi (at red-line) out of my 68HTA in the summer heat, but in the winter I can hit a bit higher.

The best I did in the cold (and it gets colder, just haven't logged yet in -20F weather) was 4.74 MAFv on a KSTech 73 mm intake.

Leslie

pump gas or e85?


perhaps im lucky but i trapped 107mph at Pueblo CO, (4900ft - greasy track) Full weight STi-

NHRA's official Altitude correction factor for that track is 1.0466

so 107 x 1.0466 = 111.98 mph.


and the official correction factors link: http://www.nhra.net/tech_specs/altitude.html

I know this thread is kinda dead but ive gotta pipe in, the hta68 is a great turbo for the 2.0, Ive got a ej207 that made 326whp on only 22psi on e85 and couldve made 300whp or close to on 93 but didnt care enough because the car was going to only run on 93 in case of an emergency. I was maxing out the 65mm intake on only 22psi so I bought the ks-tech 73mm intake and got it streetuned on 24psi, dont have any new numbers, but should the tuner said it should be around 350ish-whp on a mustang. My next plans are for a external wastegate and a 8cm housing for even more top end. Anyway heres the graph for the old tune

Makes me wonder what I should do with my new hta. Its going on a fully built 2.0. Heads were ported polished gsc 272, pistons rods. I'm thinking of getting bigger hot side.

Def get a bigger hotside. You will want it with that much headwork. I'd even go so far to say you may want a bigger turbo...

I agree. That's why I posted it. However, I don't see this one random "411whp" dyno pull any different than the higher reading vf39 or 16/18/20g pulls I have seen on a dyno. I personally believe the 411whp pull on MAP's dyno is complete and utter BS. No doubt in my mind.

Not only do I have personal experience with MAP as a business (**** would be the appropriate word here, I have never experienced such horrible customer service in all respects, including sending me the wrong parts I personally called in to order), but I have also heard stories of people going to dyno shoot out days there and making astronomically higher numbers than they precisely experienced. And to think that the thread was started by an employee of MAP.... They clearly have other motives for providing huge dyno numbers.

Regardless, the 68hta is great, for stock 2.0 heads. If someone starts throwing headwork into the mix, it's not a very good turbo. A larger hotside is mandatory (from the 7cm) and I'd even go so far as to say a larger turbo is needed.

I ran the 68hta with my headwork (bc valvtrain, 272 cams), on pump it sucked donkey balls, with E85 I made 80whp more than my small 16g and spooled the same. Boom. This is a great turbo for stock heads and high octane (it needs high octane). However, with headwork I was losing all power by 6500rpm. Hence why I now have a dom 3xt-r. I wait for the power but it provides a longer rpm power band.

I agree with that statement. It took me a large top mount and meth to make mine do anything worth while. I am sort of bummed with regard to the headwork making the power suck. Guess I'll have to rethink my hybrid strategy if my 2.0 goes pop as I was thinking of doing machining and cams.

+1 for hating on the FP 68HTA (I have one)

I started with a stock '05 ej205 and a Evo3 16g. I made about 280+ whp before I spun my rod bearing.

Next I had Maxwell power rebuild my engine as a 2.1 stroker with some head work. This was a little over two years ago. I figured I would get a new turbo for the new build, so the 68HTA seemed like a good fit for my daily driver needs. I have been regretting that decision ever since then. After my new motor was broken in, I was only hitting about 290 whp on pump gas. Dom at MPS thought that there was too much restriction in the exhaust system. We tried a diffrent turbo back and broke 300 whp. Finally we ordered a 10cm hotside from Blouch, and made it to 330 whp and called it good. I think he left it at 22 lbs boost. Needless to say, I was kind of disappointed. At the time, Dom felt like we would have done much better with an 18g. At the time I called up FP and complained. There was no way that turbo could flow 47lb/min. The support guy claimed it would at 30+ lbs, but I thought that was BS and I am very doubtful it could perform as advertised even with race gas. At least I don't have to worry about breaking my 5 speed for now, but since I am keeping my car forever now, I figure I might as well get a better matching turbo for my build.

I would love to see some dyno posts of a 18g xt on a 2.1 stoker.

Here is my dyno plot from Maxwell Power's dyno.

Back from the dead. Did end up making 387/411 with the '68 on a built motor, on 92 pump. Timed a 5.4 sec 50-100 run. Since then I blew my tranny, have just had a jdm 6-speed installed, along with bigger injectors and an ETS IC. Scheduled for a retune on the 11th this month. With the colder weather can I break 400whp on pump?

We'll see. Not that it really matters anymore. The hta68 is discontinued, and when I get a little more cash put aside I'm probably going to get myself a 20g-xt. Will anyone even want to buy my old turbo at that point?

It was posted, but I stopped paying my GoDaddy extortion fee a few months back. I'll look for a place to rehost it. I think if I renew my NASIOC supporter membership I can post some pics here.

^What 20g would you recommend? Is the xt-r worth the extra money? Im at a toss up between the 18gxtr and the 20gxtr. Haven't heard too many people running the 20gxtr's on the 2.0l.
