Forced Performance Hta Turbos

That Super99 makes some hot looking graphs. Damn..

That would be fun to play with, with a little more displacement

Considering the suggested output I think a Super99 is as at home on a 2.5L as it is a 3L.

Its got a full kilo up its sleeve, not something that is as dependent on displacement as it is outright flow. If I am leaving you a little confused do a little reading on the reg changes for 2014 F1.

Someone needs to put one of those buggers on an RB and profit greatly haha

Agree'd. VERY impressive turbo that would be awesome on something with more displacement..

[cobrAA]

hey lithium, found more info from someone mounting them on a rb26.. spool the same or a tad laggier than -5s with a bit more power. Said however, the power gain wasnt worth the cost ( especially if they are bought at owen at 1100 euro/quid. Here in USA, its 600$us.. almost half price!).

I then asked FP and said they mainly sell the hta2868 to snowmobile with only 1 turbos.. dont think 1.3l is enought for a 68mm wheels, billet or not lol.

Althought tempting, I'm not really aiming for more power but better responce.. if only they had a 63mm ( maybe..) that could be very tempting. My search for an alternative to the expensive gtx is still on

I've had a flick through the website but I'm not familiar with FP's turbos. With the new 'Super' series do they have something that is roughly the size of their HTA 3582? I'm curious of how much power this could make on a 26. Just dreaming for now but I think these turbos seem very promising. I can't believe matt has been making almost 400KW from essentially a 3076 sized turbo.

No the "Super" series are just the 94 and 99, they are named that way because FP have designed their own bb core and turbine wheel combination which are specifically "BIG" hahaha.

I haven't seen any results on an RB or Dyno Dynamics dyno but at the same time have been following these things for a while - I figure the HTA3582 would be one of the most responsive mid 400rwkw capable turbos you could get, on E85.

What you mean "has" ................. Its still IS!! lolz

And loving it

[Blackkers]

THAT would make an impressive street machine. I wonder how the response would compare to say -5's. people tend to refer to those as being ancient and laggy these days but its certainly not a big power setup

[Lithium]

Which are you comparing with -5s, the HTA3582 or the HTA3076? The HTA3582 would be quite an improvement in response, the HTA3076 wouldn't be comparable at all - its a much smaller turbo for a start.

[Blackkers]

the 3582. Seeing as 5's can make low 400's on E85 I thought it would be a fair comparison.

So a highmounted HTA3582 would be more responsive and make 10-15%ish more power than the 5's?

[Lithium]

I think it probably depends on the setup, I wouldn't say that the HTA can make more

Sorry, I should have been a bit more specific. I was making the statement in regards to the graph that was posted on the previous page from what was in the post, looks like the graph was for a 2lt.

Totally agree with your statement though, I think a 2.5 - 3lt would be more than happy to run this turbo. Just the whole ~150whp at 4.5Krpm on that graph leaves a bit to be desired on a 2lt.

This is of course if it were being used as a street and weekend track racer. If it were pure circuit/drag, then obviously the lack of low down power/torque wouldn't really matter, as you'd be hard pressed to end up below 5.5 - 6Krpm +

Awesome, I think I'll have a read regardless... seems like some good info. Thanks

In a nut shell anything that will make full use of the available 103lbm is going to spend a lot of time a long way above 4k. My comments were more so in reference to anyone on SAU building an RB25 for big power. Personally I would not be too worried about an extra 500cc when talking 1000hp.

The added cubes isn't about to turn your 1000hp weapon into a purry little kitten with a 3071 Of course, this is purely academic. I can only offer you my opinion and until such time as proof is presented to suggest otherwise you should make your own determination.

[Dajae]

Totally understood. Any turbo that makes that much power isn't exactly going to be a response monster.

Haha, purry little kitten. Like it

All in all, for what it is, I think it's a very impressive piece of kit.

Taking until ~4300rpm to crack 200kw would normally be counted as not terrible for a road car, right?

Here's a dyno plot from the soft initial pump gas tune for an RB30DET running a GT4202R - the old school requirement for 1000hp, with a lairy big cast 75mm/102mm GT-series compressor and 82mm (versus 76mm) turbine.

It's a lost closer to a mild boost level GT3071R pump gas setup on an RB25 than some might guess without looking into it - a Super99 HTZ would be quite an substantial improvement over that... the GT42 turbine alone is around 8% bigger, which is quite a large difference in turbo world.

4700rpm for 200rwkws

its not bad....a few years ago some might say it was good

I'd like to overlay Piggehs RB28 -5 graph over it

but then the 4202 would look rubbish haha

[zebra]

Actually, the 4202 is such a lazy turbo on any engine

I've seen a 383 cube LS motor whose curve looks almost the same, just needed less boost

Sorry, I'm getting confused between this post and the one in the EFR thread defending a 300rpm improvement on the premise of transient response.

[Lithium]

Eyes keep freaking out looking at that lol - you are right, well I still think it's 200kw at around 4500rpm... but yeah, maybe a bad example KINDOF but that's a HUGE turbo which I am not calling a response monster at all. Just kindof shows what a few cubes can do, Piggaz' car is hardly comparable when it's one mans mission to make the most powerful responsive "RB26" block car possible haha.

Point is, look for an RB25 making 500kw @ wheels and check what power it's making at 4000-4500rpm - then bare in mind this setup ended up almost hitting 8s in a full weight R34 GTR when it went "all in". That extra 500cc makes a huge difference!

So! Exciting news people!!!

Forced performance have just announced the release of their new FP 6466TZ!!! Basically it has the same/similar wheel dimensions as the uber turbo, PTE6466 by precision but uses Forced Performances new HTZ type aero design. Same design used on the Super99..

I am personally very excited about this new turbocharger. I cant help but think that FP have shot themselves in the foot AGAIN with this new turbo. No twin-scroll housing options...
