Turbo-charged

looking to run power street, here is your turbo!!

needless to say, we are very pleased with the results of the S368 from bullseye power / borg warner.


set up on the car is:
GE sleeved block
manley rods
9.5:1je pistons
STOCK GSR cylinder head
STOCK GSR cam shafts
super tech springs/retainers
engine built by John at absolute proformance


inline pro exhaust manifold
4 inch open downpipe
3 inch intercooler piping

Hondata S300
aem 5 bar
s300 boost control
pcs dash logger


here is the GT4294r dyno chart (100% duty cycle on boost control)



here is the S368 dyno chart (90% duty cycle on boost control)

the distributor on the car is showing signs of crapping out, and the tires were spinning pretty decent on this pull as well i think with out spinning the car could make in the 30's



for borg warner / bullseye power

i see us selling a lot of these for the guys running the power street class, and the K-series guys running turbo street!


should hopefully post some pictures of the set up and what not here shortly

That's badass but wasn't power street restricted to a 66.5mm maximum inducer?

Turbo-charged

looks like its kind of a grey area.. i'll have to make a phone call monday now that the rules are "offically" out---but everything we have been told up to this point has said that this turbo will be legal

TURBOCHARGER
Restricted to a single turbocharger. Turbocharger must utilize a
turbine housing inlet flange commonly referred to as a T04. The
turbine housing inlet flange may be smaller but may never exceed
the T04 dimensions in any direction.
All applications limited to a maximum 66mm (2.598 inches) where
the maximum compressor wheel diameter may not exceed
66.5mm (2.618 inches) measured at the point where the leading
edge of the compressor wheel meets the housing; the compressor
housing inducer diameter may not exceed 67.75mm (2.667 inches)
measured at the point where the leading edge of the compressor
wheel meets the housing. Compressor wheel inducer contours of
wheel may not be stepped, notched, or clipped; e.g., the contours
must be continuous features from the inducer to the wheel
exducer. All air entering the turbocharger must pass through the
turbocharger inlet. Injection of any liquid, gas, or any other
substance into the inlet or exhaust housing is prohibited.
Turbocharger compressor wheel must be constructed of cast or
billet aluminum. Exotic material wheels prohibited.

Here is a pic of the turbo and 2 of the test vehicle

holy cow, thats like three of my intercoolers put together!

how was the tune handled on each turbo? thanks for doing the comparison, posting up specs on each and pricing difference would be nice but i guess we can all look that up on our own...

The 368 is about 500 dollars cheaper, but this isn't a sale post, if you have questions just shoot me a PM

the 42 looks like a stonger powerband

What turbine housing was used on the s368?

its deceiving, the 368 graph was spinning the tires. with the boost a little lower (having traction) both power bands were pretty similar.

Turbo-charged

here is both cars at spring pressure: 0% duty cycle on boost controller. 10psi spring in the gate

twkdCD595

maybe I missed it but I see the duty cycles on the solenoid listed but can you list what psi each was pushing at those duty cycles?

for sharing info. openly like this after testing.

I'm kinda of confused... Like someone listed above... the 42R looks like a stronger powerband. Even with the Borg spinning the tires. It doesn't look like it was spinning bad till about 8,500 rpm. Other then that, 42 made 50 more at 6500rpm, around 80hp more at 7000rpm, 20more at 8,000 rpm, then the borg finally catches up a little after that... The Borg isn't really showing much usable Horsepower if whoever is only taking it to 10K. Also, the 42R made more Torque throughout the whole graph....

42R &gt; S368 in my opinion.

Be nice to see a 102mm exducer on the 71mm wheel from Garrett and compare that to the s372 and see which outperforms what.

Boost plots?

Here is an overlay of the two plots. I didn't do an A+ job, but it should be good enough.

turbodano

I would expect it to look like that with the tire spin in there. That is not a good showing of what the turbo can do.

Here is the 10 psi run over layed with no tire spin.
This shows a different story.

miller

do you have the gear ratio vs tq graph on those 30+ psi graphs?

I am not sure what info Tempest has available. I would like to see a clean pass with no tire spin and the boost turned up.

Hey Dan have you noticed the trend? It seems that when most of us are switching over to a Bullseye Turbo we all have trouble getting dyno charts due to wheelspin.........

doesnt bother me a bit

Cyber ITR

turbodano : are you saying that if there were no wheelspins the S368 will spool faster than a 4294R ???

Turbo-charged : what size throttle body used in that car ??

Um, it isn't why you think it is. It's because how the power is produced. It's a shove vs a push. A shove is an abrupt distribution of power. A push is less abrupt. This is what GT series turbos have always claimed to do.

This graph shows better spool and more power at 10 psi the trend will carry all the way up.
