300Kw Unopened 25 Club...

[joeyjoejoejuniorshabadoo]

It's almost the same power as mine made on Jez's dyno with 98ron so it must be there or thereabouts. Comparing it to a different dyno in a different state might be bit hit and miss.

i think he is referring to mine on e85 that was a good 40kw higher... so more a blanket statement about fuels and the turbo's capability

[joeyjoejoejuniorshabadoo]

that HTA result is nothing short of amazing!

makes me wish i still had my car so I could do a run on the same or similar boost and see the difference.

but I chickened out on 20psi

I'm sure Lithium would agree that the GT3073HTA would also be interesting to see wound up on an RB25 . I don't know if FP would ever consider doing a GT3071HTA but that could also have potential . I don't suppose anyone knows which compressor housings they use with the 71 and 73mm HTA wheels ? I think they use T04S 0.70 AR ones on GT3076HTA turbos .

Thinking about it they have a 68mmHTA compressor and I wonder if it could beat the GTX3067R for a razor sharp 300 WKW capable turbo .

FP do a HTA3071 (51lb/min) as well as the HTA3073 you are aware of, there are a few HTA2868s lurking around too. I most definitely do not overlook the HTA3073 at all, I had actually toiled over recommending that unit to 34GeeTeeTee when we first got to discussing upgrades for him which would give him improved response and no loss of power, but it became clear that he'd get a kick out of the extra headroom to go up to the 380-390rwkw (yep - we specifically discussed that power area prior to the tune).

The HTA3071 has a 51.2mm inducer, 71mm exducer so is a smaller compressor wheel than the GT3071R - again like the HTA3076 vs the GT3076R, so you would be looking at something that would make power somewhere between the GT3071R and GT3076R but be stupidly responsive.

[joeyjoejoejuniorshabadoo]

now THAT is something I would like to see!

[Lithium]

After talking to 34GeeTeeTee about his driving impressions the dyno plot doesn't do it any justice (which to be fair I always knew would be the case, but still).... it sounds nuts, I am sure he will make a post at some point on the matter. If what he has said to me so far is anything to go by, then the HTA3071 would be porn for the likes of DiscoPotato and yourself.

[discopotato03]

I was just looking at an American board and I think they quoted the 71HTA wheel as having same inducer and exducer sizes as the GTX71mm compressor only 7 blades rather than 11 . I think they also quoted these wheels as both having 51 pounds air flow capacity .

[Lithium]

They are wrong, the GTX is 54.1mm inducer which is almost the same as the HTA3076 (54.8). The HTA3076 would probably make the GTX3071R feel lazy, the HTA3071 would be something else methinks.

Hey guys,

just bought an r33 gts-25t.

makes 330rwkw @ 20psi and was tuned by Unigroup with a Power Fc

Has an unopened rb25det with:

Garrett Gt3582r 0.82

Generic Stainless Highmount

Turbosmart 45mm Gate

3.5" Kakimoto Mega N1 Exhaust w/ no cat

Siemens 750cc injectors & custom fuel rail

Turbosmart FPR

Warlbo 255 internal and Bosch 044 External Fuel pump + Surge Tank

Power FC

Freddy Plenum

Ace Intercooler

Planning to downsize to a Gt3076r 0.82, swap to a low mount steampipe manifold, fit a quieter exhaust + high flow cat.

Hoping to stay around the 280-300rwkw mark.

[joeyjoejoejuniorshabadoo]

just food for thought... if it's a street car you would get away with a stock manifold quite easily with that turbo. only time you will see a REAL benefit is if you run e85 and are pushing 350rwkw however then you are also probably going to need slightly bigger injectors.

[joeyjoejoejuniorshabadoo]

also look into the FP 3071 for that power

(so we can see some results )

Hahaha good old FP

Welcome to the club Bennis, when you get the car bring it around so i can have a look

[34GeeTeeTee]

Hey guys, We have started a dedicated HTA chat so for all info etc please post up in the new thread here -

[LTHLRB]

so who's making 320+kw with std head bolts and head gasket?

[Hanaldo]

Mat (34GeeTeeTee) is.

[B-rice]

Lol read the above posters sig

Edit.damn you beat me to it

[LTHLRB]

Well after reading that I wont be changing my gasket or head bolts. Will post up details when she screams on the dyno again.

[joeyjoejoejuniorshabadoo]

Yeah, mine was stock bolts etc

[WMDC35]

+1, stock series 1 @ around 340 on 98, shooting for a bit more soon

[Kris..]

mine made 320 on the dot with stock head gasket but ARP head studs
