The 8374 is in between an HX40 and a 3788R, which is to say much smaller than an HX52

The HX52 is about the same as a 4202R and considerably bigger than the EFR9180

This is all IMO... I don't need 1,000hp turbo, nor do i want to deal with that on the street.

If those are exducer numbers then its actually smaller then HX40 because HX40 is 60/86 compressor wheel and 76/64 exhaust wheel, nevertheless its still a good turbo.
Correction, exducer on the compressor wheel and inducer on the exhaust.

To clarify, I am talking inducer, which determines how much air can get in. The 8374 is also rated almost 80lbs/min.

But to answer OP's question...

HX40's, 35r, some of the PTE's will do you good

If 83 was the inducer number of the compressor wheel and 74 was exducer of the exhaust wheel then I wouldn't call it a turbo but a monster that thing would run circles around my HX52 all day in terms of power. I think those numbers represent 83 being the exducer of the compressor wheel and 74 inducer of a turbine wheel. My guess this turbo is something bulls eye power would call, extended tip S259. This is still 500+ HP turbo and would work great on a street car.

My ETT S200sx was absolutely tapped out at 67lbs/min.

59/80 Comp, 74/64 Turbine.

Th 8374 is bigger on the comp side (62/83), which not accounting for the change in hub design makes for a 10% increase in cross section at the inlet and combined with new aero has it rated for 79lbs/min.

The Turbine wheel, which may share the 74mm major diameter as the S200sx has nearly nothing else in common with the new Gamma-Ti turbine in the EFR, outside of the fact they are both a type of turbine.

You could take 5 seconds to research that instead of guessing...

PHUNNY, are you out there? how long till you have that E-MAP sensor installed on the new FPblack?

I guess I could have and if we all did our research then maybe there would be no use for this site

I have not sent him the sensor yet, I'm still waiting for it to show up at my house, that's probably why you don't have yours either

You could just post the findings of your research instead of ruminations.. that would still give this place purpose and keep it relevant moving forward.

I know my friend, I'm just being a bit of a smart ass

I am sure out of these 7 pages OP, has found something that will work for him

Lol i have, i decided to go with the hx-40 because of its durability and power will fit my goals, also thanks to everyone who commented legit answers. Finally i must say i am disappointed in the pissing contest this turned into.

Its the internet, it always becomes a pissing match.. & hope you enjoy the HX40 from what I've read & heard its a great turbo

Oh please!! Wnats wrong with folks having a healthy debate,no harm done and I would say a bunch of good info here. You got alot more info I bet than you thought you would receive and I did as well Dissappointed

"HX40" good choice dude, you wont be disappointed. i promise. the 40 has been so faithfull to me, im switching to a 52 but will %99 more than likely hold on to my 40 and not sell it. theyre such a awesome turbo.

Lol @ this guy's posts. You hate like fp is gucci, don't be mad you can't afford it. hx turbos and fp turbos are good in there own. Considering fp is a small company compared to the industry of holset and I think there doing a pretty good job.
Anyways you talk about 2 turbos as if ther is not a grip of other turbos like the 35Rs, the 6262, the FS635, 6562's. But glad you done with it. Any turbo with about those wheel sized with the right mods and gas type will get you those numbers. Really just depends on your piggy bank.

No doubt good info did come from this as well, i guess it is to be expected to when you ask for opinions .

I really want to tell you a thing or two but I have to watch what I say, there a lot of crybabies that like to report posts and I can't afford any more warnings who said I can't afford an FP turbo, I can buy one just to use as a display in my garage but to me its not even worth for that. They are good turbos but to a certain extent. You can't have a turbo that spools as fast as FP with bolt on housing and have it make power past 8000 rpms and if it did work like that then there would be no need for other turbos that you mentioned above.

Ask anyone who knows what's they're talking about and they will tell you that bigger housing will have more top end, that's just common sense. What determines the peak HP on an engine, its the lose of efficiency to maintain the momentum. Sure that big compressor wheel on the FP black can move some air in to the engine but you have to also think about how that air will get out of the engine.

Let's say you have 30 psi of boost entering the engine, not only does it raise the compression but it also helps to drive the piston down as its taking that air. Now think about as that one piston is taking air the other is exhausting. If your drive pressure is 40 psi then there isn't much help from your boost to drive that piston up. If you were to take one piston and filled it with 30 psi on the intake side and another piston and filled it with 40 psi from the exhaust side, which piston you think would go down? That's just physics for you. If the 3rd piston wasn't firing to keep the engine spinning forward then the difference between boost and drive pressure would spin the engine backwards so to speak.

Why do we put bigger cams, bigger valves, bigger intake manifold, bigger exhaust on our engines, well its to increase how efficient the engine can take air in and move it out. So if you take a turbo that can move a lot of air in to the engine then you will also need a good exit rout for it as well.

A small exhaust housing is not only causes a restriction for the engine to move the exhaust out but also requires more drive pressure to maintain the exhaust flow required to maintain the speed and boost of a turbo. Compressor wheel like the one in FP black should have no problem maintaining 35+ psi of boost past 8000 rpms on a 2L engine but everywhere I've searched I've seen a consistent boost drop past 7000 rpms. So if its not the compressor wheel then what is it other then a small exhaust housing.

I asked Michael in one of my posts why they don't make a bolt on housing that's larger then 8cm and he never got back to me. Maybe he didn't like me pointing out the negatives on their turbos don't get me wrong, I don't think their turbos are garbage. The turbo itself is a good unit but the housing they stuff it in does not compliment their product, that's what I've seen and that's what I think.

If you think of it in terms of price, well I think its a little over priced. If they marked them at let's say $1500 maybe they wouldn't make as much money off each turbo but they would sell a lot more of them which would spread the word out a lot further. I know because we build custom houses. We put a lot more in to our houses then most and we sell them for less then most. Sure we don't make as much money off each house as we could but in the end we still make money. Customer got a good deal that he can't stop talking about which spreads the word. I can't tell you how many houses we sold just by the word of mouth.

They make the fp35 housings that are .70 AR, bigger than 8cm. So they do make other bolt on housings. Technically the DSM82 is an fp black but with larger turbine and housing.

I guess technically not bolt on 100% save for o2 housing

This thread was really helpful. The FP Black JB is on sale for $799 (+$150 for internal gate). I still think the HX40 with a .70 AR Bep housing would be better for racing, especially on a 2.3 auto. Auto's really only have 3 gears to work with in the quarter.

The 3586 HTA (maybe the dsm86) will flow the hx40 out of the water. Eapecially if the hx40 is in bolt on form.
