This is a joke, right? There's no good times on a certain website? Wow.
Just because you may not understand how a turbo can flow more and yet still spool faster means nothing. For the longest time many thought the sun rotated around the earth. Made sense. But so does the science that disproves it. Garrett spent their money on a bandaid for the poor spool of a larger frame turbo called ballistic technology. Holset and Borg-Warner actually attacked the problem called efficiency, fluid dynamics and aerodynamics. A more efficient compressor takes less energy to reach a certain boost. Why? because less energy is wasted to heat (adaibatic process). This is one reason why preturbo water injection speeds spool. Work of the turbine = work of the compressor = Specific heat X Massflow X (Compressor temp out - compressor temp in). For less 'temp out' (higher efficiency), less work needs to be done by the turbine to generate a massflow. Residual mass in the intake tract, or mass that doesn't get into the motor, is boost. It takes less exhaust energy to spin the turbine which spins the compressor to maintain that boost. Since it takes less gases, you can use a smaller motor or you can use the same motor and have that boost come on at lower rpms (less exhaust energy). Same boost at lower rpms is called 'faster spool'. /ubbthreads/images/graemlins/cool.gif
There is a dynograph of an hx40 in the SMALL bep housing making
653whp. When does it see peak pwer vs. a small BB gt30r? Where does the small BB gt30r have more power than the hx40? how much more? How much power is under the curve? The gt3076r can't hold 40psi to redline. . . A gt35r can't even do that with that particular setup. The HX40 pro did. A gt35r doesn't spool as fast as a gt30r. But a holset hx40 in the bep housing does. There aren't to many gt35r turbos outputting 650+ whp without nitrous. . . none. So it achieved the results the owner wished.
Here is the compressor map of the above turbo (HXsuper40):
The above map, and the airflow rating listed before in the sam document where I got this map, shows 0.52/kg/sec. .52kg/sec X 60sec/min = 31.2kg/min . 31.2kg/min X 2.2046 lb/kg = 69lb/min. A 650whp car needs about 67-68lb/min airflow. Since the airflow is being pushed to the limit of the compressor map, where is the small bep housing choking flow on the super40?
The 8blade hx35 compressor map is here:
Here is a dynograph an 8blade hx35 in the bolton bep housing:
For a 52 lb/min compressor (per the map) to make 494whp means that the bolton housing is not a choke for the turbo and of course the turbo can really do it. So it achieved the results the owner wished.
Here is the timeslip and information about the first bolton 8blade hx35 reaching over 120mph and the 11s.
11.2@126mph. Here's his thread on the subject:
New times on the Holset HX-35. 272s, stock head/intake/header, stock tranny, only 28psi, and a granny-shift 1.9sec 60-ft. 2900-3000lb modestly lightened AWD at 126mph is what horsepower? Something close to the bolton 8blade hx35 dynograph above.
The 7blade hx35 compressor map is on the first pic in this post.
Here's
the logs of the 7blade hx35. Notice the 453.71g/sec peak. 0.45371kg/sec X 60sec/min = 27.2kg/min. 27.2kg/min X 2.2046lb/kg = 60lb/min. 0.46kg/sec is shown on the map and is stated by holset on the page above where I got the map. So it achieved the results the owner wished.
Logs of MY h1c, same turbine wheel as the the hx35, bolton housing evo3 manifold stock intake manifold, laggy fp2 cams:
H1C vs. small 16G. As you can see by the airflow logs, I have an EARLIER powerband with the h1c than the small 16g. This turbo has the same hotside that can flow enough for 500whp, And it has a 54mm inducer compressor that likes high boost. Spools to 20+ psi by 3500rpms and its 54mm inducer 8blade compressor flows a little less than the 56mm inducer 8blade hx35. The 8blade hx35 flows 52lb/min. If the h1c is 54mm in diameter, I can't see it flowing any less than 48lb/min which is 4lb/min less than the 8blade hx35. CONSERVATIVELY, this turbo flows as much as a td06 20g. I've already seen 40lb/min logs. Here is
what I paid for the setup. And another member on the dsmlink forums has already seen 42lb/min logs. He doesn't even run water injection yet. Same setup as mine save hks 272s instead of fp2s. He's limited to 22psi so far, because he's running 91octane. You can only see
his logs if you have access to the dsmlink forums. This turbo has achieved what the owner wishes: faster spool than an evo3 16g and will soon achieve more flow, over 45 lb/min.
Here's the slip of the hybrid hx35/40 in a full weight 1g awd:
TimG runs 11.3@132 mph. It achieved the results the owner wished. And matched up pretty to a FP3065 powered T/E/L with slicks and a better 60-ft.
Here's the
calculator everyone uses and proves to be more consistant than dynocharts, according to guys like Curt Brown and Kevin Kwaitkowsky.
The hx35 is NOT a big turbo. It has a 2.2" compressor inducer. The gt30r has a larger inducer and flows about the same, yet spools much slower. And a turbine wheel that is very close to te same size as a t3 stage 3 (t31). How many t3 stage 3 turbines are at 600whp? How many t3 stage 3 wheels can push 500whp and spool to full boost by 3600rpms? The hx40 turbine wheel is VERY close in size to the Ptrim turbine wheel. Good luck getting that turbine wheel to spool under 4600rpms with a turbine housing that will let it flow over 65lb/min. Is someone equating compressor cover size to spool and flow potential?
For having read through the tuners holset threads, you didn't pay much attention /ubbthreads/images/graemlins/wink.gif. All this information was in the 3rd or the 4th thread.
Every one lies on the dsmtuners holset threads and says the bolton hx40 turbo spools to 20+psi by 4100rpms with 272s. Everyone lies and says the hx35/h1c spools as fast as a 16g but flows at or more than a 50-trim. We just want out $400 total investment to match up to the big guns no matter the cost. Garrett's not overrated. Nope and neither is FP. I think you will be soon suprised to find out what compressor wheel is actually on the FPHTA88.
