the b-52 turbo from the speed factor -opinions?

[deez90awd]

what do you think about the b-52 from speed factor...its supposed to flow over 52lbs/min...its also built by bullseye power...just curious about yall views or experience with this turbo.

 

[Black95TSIawd]

Well, considering its a bullzeye housing, at least you know that the hot side flows well. If you opt for the internal wastegate, its a 38mm i believe which is HUGE for an internal wastegate so you should get rock solid boost control. 52lbs/min is no joke man, i hope your ready for some power. I know a kid down south of me that used the t3 inlet and with a v-band adapter, put this turbo on a 240sx with an sr20 swap, and layed down 390whp at 24psi. Add some more boost(ie 30psi with racegas) and 450+ whp is right around the corner. Marty at SpeedFactor is an awesome guy to talk to. Just call him up if you have any specific questions.

I was sorta like you, i had a few talks with martin at the speedfactor and also one of the bullseye guys and man this turbo is real sweet, if your lookin for some serious power this turbo is a great choice and the price is just unbeatable.
the turbo spools just as fast as my 20g did and makes so much more power then my 20g did, put it this way my 20g flowed 44 lbs/min and this B-52 flows 52 lbs/min...i made easy 350awhp at 20psi with stock motor with my 20g..i can imagine what numbers im gonna put down with this B-52

I have purchased this turbo as well but I have yet to put it on. Right now it is disassembled and the housings are out getting ceramic coated.

I opted for the B-52 mainly because I am hoping that there will be a bit more lag than my T-28 to help with traction issue launching the car. My T-28 would fully spool by 3000rpms which is less than my launch RPM at the track. It was like instant full boost with serious tire spinning. I only just started drag racing so I know I have a lot to learn about FWD launching but maybe this will make things a little easier as well as giving me a LOT more power. I am also hoping that I will be able to get decent HP numbers with out extremely high boost. I really don't want to HAVE to run 30psi do get into the ideal power band. Seems like I had read that 25psi & up is where the T04E 50-trim works the best. I had read in another post that the T04B V-trim was logged at about 31 lbs/min of airflow at 15psi on DSMLink. That is the most that I ever logged out of my T-28 and that was at 24psi. Maybe the B-52 will do it at 13 or 14psi... who knows?

i picked up the turbo last week...its huge....i talked to bullseye and he said with my set up this thing should be a hell of a ride...im dropping my new motor setup in next month...i cant wait

jumping on board for results after you guys install these bad boys

 

[86MCSS]

I am also interested in results after you install and dyno tune them. I am looking into upgrading from my Evo16g sometime soon. Hope to see some numbers soon

 

[khendriksma1]

Hope to see some numbers soon

Well, unfortunately, you won't see any numbers real soon from me only because for one, it is still winter here in Michigan, two, it will probably be mid-March before I can get it installed, and three, I have to find some place that has a dyno in Grand Rapids. I hope there is one but I really haven't looked that hard yet.

What compressor is this? 60 trim?

What compressor is this? 60 trim?

No details mentioned on their website.

[khendriksma1]

I don't know exactly what it is. Here are the diameters of the inducer/exducer (I might be a couple thousandths off with the exducer).

Inducer = 2.298"
Exducer = 2.674"

I am not sure if I have figured it correctly but it seems that this is a 74-trim.
Is this the correct formula? Inducer squared divided by the square of the exducer x 100? I get 73.784237003912800447177193963108 or 74-trim for short.

If this this correct, is this trim supposed to be good? I have heard that the higher the trim number the more efficient the compressor is.

 

[jjbrasil]

I was told from bullseye it is a 60trim

 

[IPT]

IT is not a 60 trim. They are only 50 lbs/min wheels and this is a 52-53 lb/min wheel.

 

[Tallen]

Sounds like a T04B-H. Nothing special, miraculous, or up to date by any means. Slap a fancy name on it and everyone goes nuts over a turbo with 1970's technology. Lol.

What is a T04B-H? Are you thinking of the H3? it is only 50 lbs/min.



I was mistaken in my previous post the 60 trim is a 52lb/min compressor wheel
My bad.

 

[khendriksma1]

How can it be a 60-trim when the inducer/exducer numbers don't generate that figure?

Is the PTE -trim that you are using really any newer technology?

it is not a tob4-h but hey thanks for playing

We are not disclosing what wheel it is but it is not the 60trim as mentioned above. It's a wheel we have used before and it has done quite well. Everyone running this had loved it so we will stick with it.

i guess while we are at it we should throw away all the t3/t4 technology since the base for most of it is 20 something years old and came off trucks/deisel/heavy equipment

im just giving you a hard time. I really like the B-52 though, it spools nice and it packs one heck of a bite.

Just for comparison, here's the numbers off my little turbo's Compressor side::

Compressor side:
• 52 trim
• 2.17 inducer
• 3.00 exducer
• 50 lb/min compressor wheel

Anchorage huh, that is awesome, i grew up in Anchorage. I went to Turnagain Elementary school and spent the weekend fishing at Kenai and Suldatna (spelling is probably way off) and the summer swimming at Jewel and Spenard Lake

Good times.

it's not the H3 wheel folks, different diameter.

If this turbo can flow what the chart shows and can spool at a certain RPM [that pleases me] and make the kinda power im looking for and last 3-4 years I dont care if it was made in the 1950s. If it works it works and at that price im willing to wait for some dyno grapgs on what this turbo does.
